Answer: 3 054 in^2

Step-by-step explanation:

Sphere volume formula = 4/3 pi r^3

So... 4/3 pi 9^3

= 3 053.63 in^2

Answer:

see explanation

Step-by-step explanation:

sum the parts of the ratio, 1 + 2 + 3 = 6 parts

Divide 180° ( sum of angles in a triangle ) by 6

180° ÷ 6 = 30° ← value of 1 part of the ratio , then

2 parts = 2 × 30° = 60°

3 parts = 3 × 30° = 90°

The angles in the triangle are 30°, 60°, 90°

Then the triangle is right angled

Answer:

Step-by-step explanation:

Let missing angles be [tex]x[/tex], [tex]2x[/tex].

As the triangle is right-angled triangle.

[tex]x + 2x + {90}^{o} = {180}^{o} [/tex]

[tex]3x = {180}^{o} - {90}^{o} [/tex]

[tex]3x = {90}^{o} [/tex]

[tex]x = {30}^{o} [/tex]

[tex]2x = 30 \times 2 \\ = {60 }^{o} [/tex]

Answer:

where is the table or how?

The 95% confidence interval for the true mean purchase total for all customers is ($113, $137).

Degrees of freedom = t* = 2.0452

The t-distribution is used when the standard deviation for the population is not known, and the bounds of the confidence interval are given according to the following rule:

[tex]X \sim N(\mu, \sigma) \implies \overline{X} \sim N(\mu,\sigma/\sqrt{n} )[/tex]

The variables of the equation are:

x bar is the sample mean.

t is the critical value.

n is the sample size.

s is the standard deviation for the sample.

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 30 - 1 = 29 df, is t = 2.0452.

The confidence interval is given as follows:

125 - 2.0452 x 32/√ (30) = $113.

The upper bound of the confidence interval is given as follows:

125 + 2.0452 x 32/√  (30) = $137.

The complete question is

"A store manager wants to investigate customer spending in his store. He randomly selects 30 customers and records their purchase total. He finds the mean to be $125 and the standard deviation to be $32. Construct and interpret a 95% confidence interval for the true mean purchase total for all customers. Use this table to determine the appropriate value of t*. Enter the degrees of freedom and the value of t* (exactly as you see it written in the table). Degrees of freedom = t* ="

I'm pretty sure it is the second one because > means it won't be filled in and it means greater than so greater than 2

Answer:

The first friend has 40 coins.

Step-by-step explanation:

The statement says that the two friend have a total of 60 coins, which can be expressed as:

x+y=60 (1), where:

x is the first friend

y is the second friend

Also, the statement says that if the first friend gives 1/4 of his coins to the second friend, they will have an equal number of coins which means that if you subtract 1/4 of the coins the first friend has this would be equal to the number of coins the second friend has now, which is:

x-1/4x=y+1/4x

x-1/4x-1/4x=y

y=x-2/4x

y=x-1/2x (2)

Next, you have replace (2) in (1) and solve for x:

x+x-1/2x=60

2x-1/2x=60

3/2x=60

x=60/(3/2)

x=(60*2)/(1*3)

x=120/3

x=40

Finally, you can replace the value of x in (2) in order to find the value of y:

y=40-1/2(40)

y=40-(20)

y=20

According to this, the answer is that the first friend has 40 coins.

Answer:

equation: 28 = 2h+ h + h or you could say 28 = 4h

h= 7

Step-by-step explanation:

since both lines are the same length they equal each other.

to get h = 7 you have to solve the equation you made.

28 = 4h

28/4 = 4h/4

7 = h

Step-by-step explanation:

Answer:

y = x + 1

Step-by-step explanation:

x + y = 6

y = -x + 6

Perpendicular slope to -1 is 1

(0,1)

y - y1 = m(x - x1)

y - 1 = 1(x - 0)

y - 1 = x

y = x + 1

Standard form:

y = x + 1

-x + y = 1

Answer:

$13.20 or $2.20

Step-by-step explanation:

Since percents are decimals, we can figure out the tip by multiplying the total by the decimal percent.

11 x .20 = 2.2

Now the answer depends on what you need the answer to be. if you need the total, it's $13.20.

If you need the tip, it's $2.20.

Answer:

A

First sequence: 1, 3, 9, 27, 81

Second Sequence: 4, 12, 20, 28, 36

Step-by-step explanation:

It is not B, bc it does not multiply correctly at the #12, it is supposed to be 27 since 9 x 3 = 27. And the second sequence starts with 0 but it is supposed to start with 4.

It is not c bc it does not even multiply by 3 but adds by 3. Second sequence is technically correct but since first sequence isn't, that isn't the answer.

It is not D because it doesn't multiply correctly at #12. Second sequence is supposed to start at 4 and not 0.
