Write a y=mx+b equation that has a slope of -1/7. Passes through the point (-2, 4)

The probability that x is greater than 77. 5 is 0.039828

Given,

Mean, μ = 80

Standard deviation, σ = 25

We have to find z score corresponding to 77.5

z = (x-μ) / σ

   \(=\frac{77.5-80}{25} \\= 0.1\)

Now we have to find P value from Z table:

P(x<77.5) = 0.46017

P(x>77.5) = 1 - P(x<77.5) = 0.53983

P(77.5<x<80) = 0.5 - P(x<77.5) = 0.039828

The probability of x greater than 77.5 is 0.039828

The cost of the bike is $40 and that accessories is $6.65

A word problem is a few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

Let the cost of the accessories be x, therefore, the cost of the bike is 6x,

According to the equation,

6x × x = 266

6x² = 266

x² = 44.33

x = 6.65

Therefore, the cost of the bike is = 6 × 6.65 = 39.94 ≈ 40

Hence, the cost of the bike is $40 and that accessories is $6.65

The equation for the slant asymptote of the given function is y = 2x - 4.

Option (B) is correct.

What is the slant asymptote of the function?

A slant asymptote of a function is a line that the function approaches, but never touches or crosses. It is a type of asymptote that occurs when the degree of the numerator of a rational function (a function that can be written as the ratio of two polynomials) is greater than the degree of the denominator.

To determine the equation for the slant asymptote of a rational function (a function that can be written as the ratio of two polynomials), we need to look at the degree (the highest power of x) of the numerator and the degree of the denominator.

The function g(x) = (2x^2 + 4x + 6) / (x + 4)

The degree of the numerator is 2 and the degree of the denominator is 1, since the x^2 is the highest power of x in numerator and x is the highest power of x in denominator.

Since the degree of the numerator is greater than the degree of the denominator, the slant asymptote will have the same degree as the numerator, which is 2.

To find the equation of the slant asymptote, we divide the numerator by the denominator using the long division method and get

2x + 2 - (x + 2)/(x + 4)

The equation of the slant asymptote will be the result of the long division, which is 2x - 4

Hence, the equation for the slant asymptote of the given function is y = 2x - 4

By knowing the circumference of the base of the cone, we see that the radius is 4 centimeters.

Notice that in the first figure, the length of the arc AB is L = 8π cm.

Then, that arc will be the bottom part of the cone. Then we can see that the circumference of the base of the cone will be equal to the length of the arc.

And remember that for a circle of radius R (like the base of the cone), the circumference is:

C = 2πR.

Then we will get:

8π cm = C =  2πR

( 8π cm)/ 2π = R

4cm = R

250 ml is equivalent to 8.4535 ounces, making it a simple conversion to remember. Keep in mind that when converting between ounces and milliliters, it is important to use accurate conversion factors to ensure that your measurements are accurate.

Ounces and milliliters (ml) are both units of measurement for volume. Ounces are commonly used in the United States and some other countries, while milliliters are widely used in the metric system.

One important thing to remember is that 1 ounce equals 29.5735 milliliters.

To convert 250 ml to ounces, we divide 250 by 29.5735. Therefore, 250 ml is approximately equal to 8.4535 ounces. Understanding the conversion between ounces and milliliters is important, especially in the field of cooking, baking, and medicine.

The values of a and b for the probability density function are a = 56 and b = 216.

According to the given information, the mean daily spending by Americans earning over $90,000 per year was $136 per day, and the probability density function is given by f(x) = 0.00625 for a ≤ x ≤ b.

To find the values of a and b for the probability density function, we can use the formula for the mean of a uniform distribution:

mean = (a + b)/2

Substituting the given mean value of $136 into the formula, we get:

136 = (a + b)/2

Multiplying both sides of the equation by 2, we get:

272 = a + b

Rearranging the equation, we get:

b = 272 - a

Now, we can use the formula for the area under the probability density function, which is equal to 1:

∫_a^b f(x) dx = 1

Substituting the given probability density function and the value of b into the formula, we get:

∫_a^(272-a) 0.00625 dx = 1

Simplifying the integral, we get:

0.00625(272 - 2a) = 1

Dividing both sides of the equation by 0.00625, we get:

272 - 2a = 160

Rearranging the equation, we get:

2a = 112

Dividing both sides of the equation by 2, we get:

a = 56

Substituting the value of a back into the equation for b, we get:

b = 272 - 56 = 216

Answer:

$61.82

Step-by-step explanation:

2(9.99) + 3(12.60) = $57.78

Now that we know the total, let's find out how much is 7% of the total.

57.78 * 0.07 = approx. 4.04

Now, add that value to the total:

57.78 + 4.04 = $61.82

Answer:

$61.82

Step-by-step explanation:

$9.99 x 2 = $19.98

$12.60 x 3 = $37.80

$19.98 + $37.80 = $57.78

$57.78 x 7 = 404.46

404.46 divided by 100 = 4.0446

$57.78 + $4.04 = $61.82

What is perimeter?

A closed path which encompasses, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter. A circle's or an ellipse's circumference is referred to as its perimeter. There are numerous uses in real life for perimeter calculations. The measurement of the fence needed to completely enclose a yard as well as garden is called the perimeter.

The hypotenuse of a triangle must be longer than the other sides.

Answer:

Step-by-step explanation:

Sum of 3 angles of a triangle= 180

3x-2+x+11+4x+3= 180

Separate x terms from constants

3x+x+4x-2+11+3= 180  

8x+12= 180

8x= 180-12

8x= 168

x= 168/8

x= 21

Put the value of x in angles:

3x-2=3(21)-2= 63-2= 61

x+11= 21+11= 32

4x+3= 4(21)+3= 84+3= 87

If you want to check whether your answer is right or wrong, you can cross-check by adding the 3 angles

Answer:

To solve this problem, let's break it down step by step.

1. Find the difference in height between the highest and lowest point of the handle:

The difference in height is 9 feet - 4 feet = 5 feet.

2. Calculate the circumference of the flywheel:

The circumference of a circle can be found using the formula C = πd, where C is the circumference and d is the diameter.

The diameter is given as 5 feet, so the circumference is C = π(5) = 5π feet.

3. Determine the vertical distance covered by the handle in one revolution of the flywheel:

Since the handle is attached to the edge of the flywheel, it moves in a circular path as the flywheel rotates.

The circumference of the flywheel represents the distance covered by the handle in one revolution.

Therefore, the vertical distance covered is also 5π feet.

4. Calculate the speed of the handle:

The wheel makes a complete turn every 2 seconds, which means it completes one revolution in 2 seconds.

Therefore, the speed of the handle is the vertical distance covered (5π feet) divided by the time taken (2 seconds):

Speed = (5π feet) / (2 seconds) = (5/2)π feet per second.

The probability mass function for this problem is f(x) = C(20, x) * (0.65)^x * (0.35)^(20-x). The parameters for this binomial distribution are n=20 (number of trials) and p=0.65 (probability of success).

Based on the given information, x follows a binomial distribution since each passenger either belongs to the frequent rider club or not, with a fixed probability of 0.65 for success (being a member of the club) and 0.35 for failure (not being a member). The probability mass function (f(x)) for this distribution can be written as f(x) = (20 choose x) * 0.65^x * 0.35^(20-x), where (20 choose x) represents the number of ways x passengers can be chosen from a total of 20 passengers. The parameters for this distribution are n = 20 (the total number of passengers) and p = 0.65 (the probability of success).
Hi! Based on your question, the variable X follows a binomial distribution since it represents the number of successes (frequent rider club members) out of a fixed number of independent Bernoulli trials (20 passengers). The probability mass function (f(x)) for a binomial distribution is given by:
f(x) = C(n, x) * p^x * (1-p)^(n-x)
where:
- C(n, x) represents the number of combinations of n items taken x at a time (n choose x)
- n is the number of trials (20 passengers in this case)
- x is the number of successes (number of frequent rider club members)
- p is the probability of success (0.65 for a passenger being part of the frequent rider club)
- (1-p) is the probability of failure (0.35 for a passenger not being part of the frequent rider club)
