Answer:

Yes this is a resendable prediction

Step-by-step explanation:

Applying the formula, it is found that the SP for both numbers is of 7.

The first step is finding the mean for both sets, hence:

\(M_x = \frac{4 + 0 + 1 + 3}{4} = 2\)

\(M_y = \frac{5 + 2 + 1 + 4}{4} = 3\)

Then, the SP(sum of products of deviations) is the sum of the multiplications between each value x and the mean, with each respective value of y(same index) and the mean, hence:

\(SP = (4 - 2)(5 - 3) + (0 - 2)(2 - 3) + (1 - 2)(1 - 3) + (3 - 2)(3 - 4) = 7\)

The SP for both numbers is of 7.

Answer: Minimum sample size = 110

Step-by-step explanation:

Formula to find minimum sample size :

\(n=(\dfrac{z\times s}{E})^2\) , where z = critical z-value for confidence level, s= sample standard deviation , E = margin of error

Given: E= 4 , s= 18

Critical z-value for 98% confidence = 2.327

So,  \(n=(\dfrac{2.327\times18}{4})^2\)

\(=(\dfrac{41.886}{4})^2\\\\=(10.4715)^2=109.65231225\approx110\)

Minimum sample size = 110

Answer:

\(\frac{3\pi}{4}\)

Step-by-step explanation:

Recall that co-terminal angles are angles which when drawn at standard position share a terminal side. Since we are restricted to the interval [0,2π], recognize that \(\frac{19\pi}{4}=\frac{16\pi}{4}+\frac{3\pi}{4}=4\pi+\frac{3\pi}{4}=2\pi+2\pi+\frac{3\pi}{4}=\frac{3\pi}{4}\). So, the co-terminal angle is \(\frac{3\pi}{4}\).

A randomized experiment with order, replacement, and no repetition is one in which the order of the outcomes matters, the same outcome can occur multiple times, and no outcome can occur more than once.

For example, drawing a card from a deck and then flipping a coin would be a random experiment with order, replacement, and no repetition. The order of the results is important because the outcome of the coin toss will depend on the outcome of the card draw.

The same result can occur multiple times because the same card can be drawn twice, and no result can occur more than once because the coin can only land heads or tails once.

Option(A) is the correct answer is A. 1,335 birds.

To calculate the number of birds that will be left after 20 years, we need to consider the annual decline rate of 2%.

We can use the formula for exponential decay:

N = N₀ * (1 - r/100)^t

Where:

N is the final number of birds after t years

N₀ is the initial number of birds (2,000 in this case)

r is the annual decline rate (2% or 0.02)

t is the number of years (20 in this case)

Plugging in the values, we get:

N = 2,000 * (1 - 0.02)^20

N = 2,000 * (0.98)^20

N ≈ 2,000 * 0.672749

N ≈ 1,345.498

Rounded to the nearest whole number, the number of birds that will be left after 20 years is 1,345.

The total cost of the camera with sales tax included is $793.44

The listed  price of camera = $722.95

The sales tax rate = 9.75%

The amount of tax = The listed  price of camera × (The sales tax rate / 100)

Substitute the values in the equation

The amount tax = 722.95 × (9.75 / 100)

Divide the terms first

= 722.95 × 0.0975

Multiply the terms

= $70.49

The cost of the camera including tax = The listed  price of camera + The amount tax

Substitute the values in the equation

= 722.95 + 70.49

= $793.44

Hence, the total cost of the camera with sales tax included is $793.44

The equations which represent circles that have a diameter of 12 units and a center that lies on the y-axis include the following:

(x - 0)² + (y - 3)² = 36

(x - 0)² + (y + 8)² = 36

Mathematically, the standard form of the equation of a circle is given by;

(x - h)² + (y - k)² = r²

Where:

Since the circle has a diameter of 12 units, the radius would be calculated as follows:

Radius, r = diameter/2

Radius, r = 12/2

Radius, r = 6 units.

Also, when the center of this circle lies on the y-axis, it simply means the value of h is zero (0). Therefore, the equations of these circle at points (0, 3) and (0, -8) are given by;

(x - h)² + (y - k)² = r²

(x - 0)² + (y - 3)² = 6²

(x - 0)² + (y - 3)² = 36

(x - h)² + (y - k)² = r²

(x - 0)² + (y - (-8))² = 6²

(x - 0)² + (y + 8)² = 36

Approximately 99.7% of scores lie in the shaded region.

We have,

The empirical rule, also known as the 68-95-99.7 rule, provides an estimate of the percentage of scores that lie within a certain number of standard deviations from the mean in a normal distribution.

According to this rule:

Approximately 68% of scores lie within 1 standard deviation of the mean.

Approximately 95% of scores lie within 2 standard deviations of the mean.

Approximately 99.7% of scores lie within 3 standard deviations of the mean.

Now,

In the given scenario, the shaded region represents the area between -2 and 3 standard deviations from the mean on the x-axis.

This encompasses the area within 3 standard deviations of the mean.

And,

Since 99.7% of scores lie within 3 standard deviations of the mean, we can estimate that approximately 99.7% of scores lie in the shaded region.

1) x = -17 +6y + 2z/3

2) x= -13 - 4y - 5z/6

3) x= -22 +4y + 3z/3

Step-by-step explanation:

1) 3x-6y-2z=-17

3x- 6y -2z- (-6y -2z)= - 17 - ( 6y -2z )

3x=-17+6y+2z

3x/3= -17/3 +6y/3 + 2z/3

x = -17 +6y + 2z/3

2) −6x+4y+5z=13

-6x+4y+5z- ( 4y + 5z )= 13 - ( 4y + 5z )

-6x=13-4y-5z

-6x/-6= 13/-6 - 4y/-6 - 5z/-6

x= -13 - 4y - 5z/6

3) −3x−4y−3z=22

-3x=22+4y+3z

Answer:

The quadratic equation is in the standard form: ax^2 + bx + c = 0. To use the quadratic formula to find the solutions, we need to identify the values of a, b, and c in the equation:

a is the coefficient of the x^2 term, which is -3 in this case.

b is the coefficient of the x term, which is -5 in this case.

c is the constant term, which is 9 in this case.

Therefore, the values of a, b, and c in the quadratic equation -3x^2 - 5x + 9 = 0 are:

a = -3

b = -5

c = 9

Answer:

b. What value will be exceeded 10% of the time?

c. What value will be exceeded 85% of the time?

= 19.82

d. Determine two values of which the smallest has 25% of the values below it and the largest has 25% of the values above it.

The two values are: 21.63 and 28.37

Step-by-step explanation:

We solve using the z score formula:

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

A random variable is normally distributed with a mean of 25 and a standard deviation of 5. If an observation is randomly selected from the distribution.

Required:

a. What value will be exceeded 75% of the time?

We are to find the value x

Exceeded by 75% = 100 - 75 = 25

We find the z score of 25% percentile

= -0.674

Hence:

-0.674 = x - 25/5

Cross Multiply

-0.674 × 5 = x - 25

-3.37 = x - 25

x = 25 - 3.37

x = 21.63

b. What value will be exceeded 10% of the time?

We are to find the value x

Exceeded by 90% = 100 - 90 = 10

We find the z score of 90% percentile

= 1.282

Hence:

1.282 = x - 25/5

Cross Multiply

1.282 × 5 = x - 25

6.41 = x - 25

x = 6.41 + 25

x = 31.41

c. What value will be exceeded 85% of the time?

We are to find the value x

Exceeded by 85% = 100 - 85 = 15

We find the z score of 15% percentile

= -1.036

Hence:

-1.036 = x - 25/5

Cross Multiply

-1.036 × 5 = x - 25

-5.18 = x - 25

x = 25 - 5.18

x = 19.82

d. Determine two values of which the smallest has 25% of the values below it and the largest has 25% of the values above it.

This means their z score is 25% below the mean and 25% above the mean

We are to find the value x

We find the z score of 25 % and 75% percentile

= - 0.674 and 0.674

Hence:

For -0.674

-0.674 = x - 25/5

Cross Multiply

-0.674 × 5 = x - 25

-3.37 = x - 25

x = 25 - 3.37

x = 21.63

For 0.674

0.674 = x - 25/5

Cross Multiply

0.674 × 5 = x - 25

3.37 = x - 25

x = 25 + 3.37

x = 28.37

Therefore, the two values are: 21.63 and 28.37

The correct order from least to greatest is log₂ 26, log₂ 33, log 26, eln 4, the correct option is D.

We are given that;

The logs log, 26, log, 33 and log3 26

Now,

We can simplify these expressions using the following identities:

eln x = x

log a a = 1

log a (b × c) = log a b + log a c

log a (b / c) = log a b - log a c

Using these identities and the properties of logarithms listed above, we can compare the given expressions as follows:

A. eln 4 = 4; log 26 < log 33; so we have:

4 < log 26 < log 33

B. eln 4 = 4; so we have:

log 33 < 4 < log 26 < log 26

C. eln 4 = 4; so we have

log₂ 26 < log 26 < log 33 < 4

D. eln 4 = 4; so we have:

log₂ 26 < log₂ 33 < log 26 < 4

Therefore, by logarithm the answer will be log₂ 26, log₂ 33, log 26, eln 4.
