The hours 1,100 hours on Saturn is equivalent to 100 days on Earth and Mars
How to determine the number of days of 1100 hours?From the question, we have the following table of values that can be used in our computation:
Planet Length of one day (hours)
Earth 24
Mars 25
Saturn 11
Also, we have
Number of hours on Saturn = 1100
So, we can represent the table of values as a ratio
Earth : Mars : Saturn = 24 : 25 : 11
Substitute Number of hours on Saturn = 1100 in the ratio
Earth : Mars : 1100 = 24 : 25 : 11
Multiply the ratio by 100
So, we have
Earth : Mars : 1100 = 2400 : 2500 : 1100
This means that
Earth = 2400 hours
Mars = 2500 hours
Divide by 24 and 25
Earth = 100 days
Mars = 100 days
Hence, the number of days on Earth is 100 days

Round your answers to two decimal places (e.g. 98.76). (a) The probability is (b) The probability is (c) The probability is
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Probability of mutation = 2% = 0.02
Number of samples(n) = 18
nCk × (p^k) × (1 - p)^(n-k)
P = probability of success
n = number of trials
k = number of success desired
A) P(n, k) = p(18, 0) = 18C0 × 0.02^0 × 0.98^18
P(18,0) = 1 × 1 ×0.6951353 = 0.6951
0.6951 × 100% = 69.50%
B.) At most one Sample is mutated
P(x =0) + p(x = 1)
P(18,0) = 69.5%
P(18, 1) = 18C1 × 0.02^1 × 0.98^17
P(18,0) = 18 × 0.02 × 0.70932176618 = 0.25535
0.2553 × 100% = 25.5%
69.5% + 25.5% = 95.00%
C) More than half the samples are mutated
Half of samples (18 / 2) = 9
P(x> 9) : p(x = 9) + p(x = 10)... +p(x = 18)

A computer technician charges $190 for a 3-hour appointment and $370 for a 7-hour appointment. Which of these represents a linear function that models the charge for hiring the technician for x hours? A y=55x+190 B y=55x+45 C y=45x+190 D y=45x+55
Answer:
The linear function that models the charge for hiring the technician for x hours is y=45*x + 55
Step-by-step explanation:
The linear function is defined by the equation
f(x) = mx + b or y = mx + b
where m is the slope of the line and b is the y-intercept.
In this case you want to represent a linear function that models the charge for hiring the technician for x hours, that is, y represents the charge for hiring the technician and x the number of hours.
Given the coordinates of two points (x1, y1) and (x2, y2), you can determine the equation of the line first knowing the slope m by:
\(m=\frac{y2-y1}{x2-x1}\)
In this case, the points are:
(x1,y1)= (3,190)(x2,y2)= (7,370)So:
\(m=\frac{370-190}{7-3}\)
Solving:
m=45
To obtain the value of b, once you have replaced the value of m in the equation, you must substitute the values of x and y for the values of the coordinates of one of the points, and solve for b to obtain its value. In this case you replace the value of point 1:
\(y=45*x+b\)
\(190=45*3+b\)
And you get:
190= 135 + b
190 - 135= b
55= b
So, the linear function that models the charge for hiring the technician for x hours is y=45*x + 55
We want to find a linear equation that models the charge for hiring the technician for x hours.
The correct option is D, the equation is:
y = ($45/h)*x + $55
We know that a general linear equation is written as:
y = a*x + b
where a is the slope and b is the y-intercept.
If the line passes through two points (x₁, y₁) and (x₂, y₂) then the slope can be written as:
\(a = \frac{y_2 - y_1}{x_2 - x_1}\)
Here we have two points, one given by:
(3 hours, $190)
The other given by:
(7 hours, $370)
Then the slope is given by:
\(a = \frac{\$ 370 - \$ 190}{7h - 3h} = \$ 45/h\)
This means that he charges $45 per hour.
Replacing that in the general equation we get:
y = ($45/h)*x + b
To find the value of b, we use the fact that he charges $190 for 3 hours, then we can solve:
$190 = ($45/h)*3h + b
$190 = $135 + b
$190 - $135 = b = $55
Then the equation is:
y = ($45/h)*x + $55
So the correct option is D.

The values of the trigonometric functions are:
cos(x) = -7/25
sin(x) = 24/25
tan(x) = -24/7
sec(x) = -25/7
cot(x) = -7/24
We have,
We can start by using the definition of cosec(x) = 1/sin(x) to find sin(x):
csc(x) = 25/24
1/sin(x) = 25/24
sin(x) = 24/25
Now we can use the Pythagorean identity sin²(x) + cos²(x) = 1 to find cos(x):
sin^2(x) + cos^2(x) = 1
(24/25)^2 + cos^2(x) = 1
cos^2(x) = 1 - (24/25)^2
cos(x) = -7/25
(since x is in the second quadrant where cos(x) is negative)
Next, we can use the definition of tan(x) = sin(x)/cos(x) to find tan(x):
tan(x) = sin(x)/cos(x) = (24/25)/(-7/25) = -24/7
Using the reciprocal identities, we can find sec(x) and cot(x):
sec(x) = 1/cos(x) = -25/7
cot(x) = 1/tan(x) = -7/24
Therefore,
The remaining trig functions are:
cos(x) = -7/25
sin(x) = 24/25
tan(x) = -24/7
sec(x) = -25/7

(a) What is the lower limit of this 90% confidence interval?
lower limit = (2 decimal places)
(b) If 500 random samples like this were selected, and a 90% confidence interval was constructed using each sample, approximately how many of these confidence intervals would contain the population mean?
(whole number)
Step-by-step explanation:
(a) The lower limit of the 90% confidence interval can be calculated using the formula:
lower limit = sample mean - margin of error
Plugging in the given values, we have:
lower limit = 7.43 - 1.32
lower limit = 6.11 (rounded to 2 decimal places)
Therefore, the lower limit of the 90% confidence interval is approximately 6.11 hours per night.
(b) If 500 random samples like this were selected, and a 90% confidence interval was constructed using each sample, the expected number of intervals that would contain the population mean can be approximated using the margin of error as a guide.
Since the margin of error is 1.32 hours, we can expect roughly 90% of the confidence intervals to contain the true population mean. Therefore, out of 500 samples, we would expect approximately:
500 * 0.9 = 450
So, approximately 450 of these confidence intervals would contain the population mean.

The mean height of an adult giraffe is 19 feet. Suppose that the distribution is normally distributed with standard deviation 1 feet. Let X be the height of a randomly selected adult giraffe. Round all answers to 4 decimal places where possible.
a. What is the distribution of X? X - N b. What is the median giraffe height? ft. c. What is the Z-score for a giraffe that is 22 foot tall?
d. What is the probability that a randomly selected giraffe will be shorter than 18.9 feet tal?
e. What is the probability that a randomly selected giraffe will be between 18.6 and 19.5 feet tall?
f. The 80th percentile for the height of giraffes is ft.
a. The distribution of X is a normal distribution.
b. The median giraffe height is also 19 feet.
c. The Z-score for a giraffe that is 22 foot tall is 3.
d. The probability that a randomly selected giraffe will be shorter than 18.9 feet tall is less than -0.1.
f. The 80th percentile represents the value below which 80% of the data falls.
a. The distribution of X is a normal distribution (or Gaussian distribution) with a mean of 19 feet and a standard deviation of 1 foot. This can be denoted as X ~ N(19, 1).
b. The median of a normal distribution is equal to its mean.
c. To find the Z-score for a giraffe that is 22 feet tall, we can use the formula: Z = (X - μ) / σ, where X is the observed value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get Z = (22 - 19) / 1 = 3.
d. To find the probability that a randomly selected giraffe will be shorter than 18.9 feet tall, we need to calculate the area under the normal curve to the left of 18.9. This can be done using the Z-score and a standard normal distribution table or a calculator.
Alternatively, we can use the Z-score formula from the previous question. The Z-score for 18.9 feet can be calculated as Z = (18.9 - 19) / 1 = -0.1. We can then look up the corresponding probability in the standard normal distribution table or use a calculator to find the probability that Z is less than -0.1.
e. To find the probability that a randomly selected giraffe will be between 18.6 and 19.5 feet tall, we need to calculate the area under the normal curve between these two values.
Again, we can use the Z-score formula to standardize the values and then find the corresponding probabilities using a standard normal distribution table or a calculator.
f. To find the height at the 80th percentile, we can use the standard normal distribution table or a calculator to find the Z-score that corresponds to the 80th percentile.
Once we have the Z-score, we can use the formula Z = (X - μ) / σ to solve for X. Rearranging the formula, we have X = Z * σ + μ. Plugging in the values for Z (obtained from the percentile) and μ (mean) and σ (standard deviation), we can calculate the height at the 80th percentile.

Find the measure of the three missing angles in the rhombus below.
Answer:
x=67
y=67
z=113
Step-by-step explanation:
Because this is a rhombus, that means that angle 113 and z are correlating, and angle y and x correlate. This is a four-sided shape, so the total of all four angles will add up to 360.
113 and z are correlating, so z is 113.
To find the other two, we first need to find out how much angle measurement is left. To do this, we will subtract angle 113 and z from 360 (our total).
This gives us 134 degrees left.
Now, since x and y are equal to each other, that means that their measurements will be exactly half of the remainder we just found.
So taking 134 and dividing it by 2, we get our final two measurements for x and y, 67 degrees each.
Answer:
x = 67
y = 67
z = 113
Work:
There are a total of 360 degrees in a rhombus and a straight line is 180 degrees. You also know that opposite angles in a rhombus are equal.
If z is opposite 113, then z = 113.
Then to find x, 180 - 113 = 67.
If x is 67 then y is 67 since they are opposite angles.

10. The stamp duty payable on a property with a purchase price of K150,000 is K7,500.
To calculate the stamp duty payable on properties with a purchase price of K45,000 and K150,000, we need to apply the corresponding rates of stamp duty based on the given information.
Given:
Value of Property:
Up to K35,000: Stamp Duty Rate - 2%
K35,000 to K70,000: Stamp Duty Rate - 3%
K70,000 to K140,000: Stamp Duty Rate - 4%
Over K140,000: Stamp Duty Rate - 5%
9. Calculate the stamp duty payable on properties whose purchase price is K45,000:
Since the purchase price of K45,000 falls within the range of K35,000 to K70,000, the stamp duty rate applicable is 3%.
Stamp Duty Payable = Purchase Price * Stamp Duty Rate
= K45,000 * 3%
= K45,000 * 0.03
= K1,350
Therefore, the stamp duty payable on a property with a purchase price of K45,000 is K1,350.
10. Calculate the stamp duty payable on properties whose purchase price is K150,000:
Since the purchase price of K150,000 is above K140,000, the stamp duty rate applicable is 5%.
Stamp Duty Payable = Purchase Price * Stamp Duty Rate
= K150,000 * 5%
= K150,000 * 0.05
= K7,500
Therefore, the stamp duty payable on a property with a purchase price of K150,000 is K7,500.

Find an autonomous differential equation with all of the following properties:
equilibrium solutions at y=0 and y=3,

y' < 0 for -inf < y < 0 and 3 < y < inf
dy/dx = ______
dy/dx = (y-3)(y+3) is the autonomous differential equation that satisfies all of the given properties.
The autonomous differential equation that satisfies all of the given properties is dy/dx = (y-3)(y+3). This equation has two equilibrium solutions at y = 0 and y = 3, and is positive for -inf < y < 0, and negative for 0 < y < 3, and positive for 3 < y < inf.
To demonstrate this, let's consider the equation at y=-3. Since y=-3 is less than 0, the equation can be simplified to dy/dx = 6. Since 6 is positive, y' is also positive, meaning that y is increasing. Similarly, if y=3, dy/dx = 0 which is neither positive nor negative, so y remains constant. Finally, for y>3, dy/dx = -6, which is negative, so y is decreasing.
Therefore, dy/dx = (y-3)(y+3) is the autonomous differential equation that satisfies all of the given properties.

What is the perimeter of polygon LMNPQ
Answer: c for maps
Step-by-step explanation:
17.66 units is the perimeter of the polygon.
What is Perimeter?The perimeter of a two-dimensional form is the space surrounding it. It represents the total length of the shape's sides. The units used to measure the sides of the form, such as meters, centimeters, inches, or feet, determine the units used to measure the perimeter.
To find the perimeter of the polygon LMNPQ, we need to add up the lengths of all the sides.
The distance formula for finding the distance between two points \((x_1, y_1)\) and \((x_2, y_2)\) is:
\(d = \sqrt{(x_2 - x_1)^2 + (y-2 - y-1)^2)\)
Using this formula, we can find the lengths of each side of the polygon:
\(LM = \sqrt{(2 - 4)^2 + (4 - 2)^2} = \sqrt{8}\\MN = \sqrt{(5 - 2)^2 + (8 - 4)^2} = \sqrt{25}\\NP = \sqrt{(8 - 5)^2 + (4 - 8)^2}= \sqrt{25}\\PQ = \sqrt{(6 - 8)^2 + (2 - 4)^2} = \sqrt{8}\\QL = \sqrt{(4 - 6)^2 + (2 - 2)^2} = 2\)
Therefore, the perimeter of the polygon LMNPQ is:
Perimeter = LM + MN + NP + PQ + QL
= √8 + √25 + √25 + √8 + 2
≈ 2.83 + 5 + 5 + 2.83 + 2
≈ 17.66
So, the perimeter of the polygon LMNPQ is approximately 17.66 units.

Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '27' to each side of the equation.
-27 + 27 + 9v = 0 + 27
Combine like terms: -27 + 27 = 0
0 + 9v = 0 + 27
9v = 0 + 27
Combine like terms: 0 + 27 = 27
9v = 27
Divide each side by '9'.
v = 3
Simplifying
v = 3

True or False: If the discriminant is less than zero, then the graph will never cross the x-axis.
False
True
Answer:
True
Step-by-step explanation:
If the discriminant \(D=b^2-4ac < 0\), then there are two complex roots
If the discriminant \(D=b^2-4ac > 0\), then there are two real roots
If the discriminant \(D=b^2-4ac=0\), then there is only one real root
