Answer:

g (x) = 2 ^ (x + 2)

Step-by-step explanation:

For this case the transformation of f (x) is given by

g (x) = 2 ^ (x + 2)

To prove it, we must verify that equality is met by replacing the ordered pairs shown in the function g (x)

For (-2,1)

g (-2) = 2 ^ ( -2 + 2)

g(-2)=1

For (-1,2)

g (-1) = 2 ^ ( -1+ 2)

g(-1)=2

For (0,4)

g (0) = 2 ^ ( 0+ 2)

g(0)=4

A sample is chosen randomly from a population that was strongly skewed to the left. a) Describe the sampling distribution model

Nana76 [90]

Answer:

a. The sampling distribution for the sample mean will be skewed to the left centered at the average u, and standard deviation will be ∅ $/\sqrt{n}$

b. The sample distribution will be normal in shape and will be centered at the average u, . standard deviation will be ∅ $/\sqrt{n}$ 1

c. As the size of the sample increases, the sample distribution should draw near and resemble the distribution of the population

Step-by-step explanation:

A sample is chosen randomly from a population that was strongly skewed to the left. a) Describe the sampling distribution model for the sample mean if the sample size is small. b) If we make the sample larger, what happens to the sampling distribution model’s shape, center, and spread? c) As we make the sample larger, what happens to the expected distribution of the data in the sample?

The following answers will march the questions above:

a. The sampling distribution for the sample mean will be skewed to the left centered at the average u, and standard deviation will be ∅ $/\sqrt{n}$

b. The sample distribution will be normal in shape and will be centered at the average u, . standard deviation will be ∅ $/\sqrt{n}$ 1

c. As the size of the sample increases, the sample distribution should draw near and resemble the distribution of the population

John is w years old. His sister is 16 years old and his brother is twice johns age all three siblings have a total age of 31

Kisachek [45]

Answer:

Step-by-step explanation:

John's age = w

His brother's age = 2*w = 2w

His sister's age = 16 years

Total age of all siblings = 31

w + 16 + 2w = 31

w + 2w + 16 = 31

Combine like terms

3w + 16 = 31

Subtract 16 from both sides

3w = 31 - 16

3w = 15

w = 15/3

w = 5

$\boxed{\text{John's age = 5 years }}$

His brother's age = 2w

= 2*5

= 10

$\boxed{\text{John's brother's age = 10 years}}$

A carpenter can build a cabinet in three hours at this rate how long will it take for the carpenter to build 26 cabinets

Ludmilka [50]

Answer: 78 hours

Step-by-step explanation:

1 cabinet = 3 hours

26 cabinets= 78 hours

We must multiply 26 by 3 to get the total amount of hours.

26x3=78

You must scuba dive to the entrance of your room at Jules' Undersea Lodge in Key Largo, Florida. The diver is 1 foot deeper than

liubo4ka [24]

Answer:

the elevation of the entrance is -21

Step-by-step explanation:

The computation of the elevation of the entrance is shown below;

-15 = -1 + 2 ÷ 3e

e = -21

Hence, the elevation of the entrance is -21

We simply applied the above equation so that we can determine the elevation of the entrance
