Answer:
The p-value for this test is 0.013.
Step-by-step explanation:
To solve this question, we need a t-distribution calculator.
We have that:
t-statistic, so the t-distribution is used.
We need to find the p-value of the t-distribution with t = -2.56, 61 - 1 = 60 degrees of freedom, in a two-tailed hypothesis test.
With the help of a calculator, this p-value is of 0.013.

If a $100 per month annuity was offering an annual 4.8% interest compounded monthly, how much money would be in the account after two years? Round your answer to the nearest cent, and do not include a dollar sign in your answer.
Answer:
109.6
Step-by-step explanation:
100+100×(4.8%×2)=100+ 100×9.6%=100+9.6=109.6
Answer:
The money account after two years will be 110.054
Step-by-step explanation:
Compound interest formula[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
A = final amount = required to know
P = initial principal balance = $100
r = interest rate = 4.8%=4.8/100 because compounded monthly
n = number of times interest applied per time period = 12
t = number of time periods elapsed = 2
[tex]A = P(1 + \frac{4.8}{1200})^{24}[/tex]
[tex]A= 100(1+0.004)^{24}[/tex]
A= [tex]110.054[/tex]
Thus, The money account after two years will be 110.054

Step-by-step explanation:
Given that,
X(seconds) 0 1 2 3 4
Y (feet) 0 1 4 9 16
We need to find the average rate of change between 1 seconds and 4 second.
X = 4-1 = 3 seconds
Y = 16 - 1 = 15 feet
We know that,

If the edges of a rectangular prism are increased by a scale factor of 3, how will the volume change
O A. The new volume is 3 times the old volume,
B. The new volume is 9 more than the old volume.
O C. The new volume is 9 times the old volume,
D. The new volume is 27 more than the old volume,
O E. The new volume is 27 times the old volume,
9514 1404 393
Answer:
E. The new volume is 27 times the old volume
Step-by-step explanation:
If L, W, and H are the original length, width, and height, then the original volume is ...
V = LWH
The volume after the scale factor is applied is ...
V' = L'W'H' = (3L)(3W)(3H) = 27LWH = 27V
The new volume is 27 times the old volume.

a =

Answer:
a = 28 / √2
Step-by-step explanation:
Isosceles triangle therefor a = b
use pythagorean theorem
a² + a² = c²
2a² = 28²
a² = 28² / 2
Take the square root of both sides
a = 28 / √2
Answer:
a = [tex]\frac{28}{\sqrt{2} }[/tex]
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{a}{28}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
a × [tex]\sqrt{2}[/tex] = 28 ( divide both sides by [tex]\sqrt{2}[/tex] )
a = [tex]\frac{28}{\sqrt{2} }[/tex]

O1/4
Since the expression is equal to "c" hence the value of c in the equation is 1/4

Simplify the exponent
2‐⁴ = 1/2⁴ = 1/16
2² = 4
Substitute
2‐⁴• 2² = 1/16 * 4
2‐⁴ • 2² = 1/4

Find the value of x by using the exterior angle theorem.
Answer:
The first choice (12)
Step-by-step explanation:
i'm not 100% what the theory is but here is how I did it:
the angle D and 115% are supplementary which means they add up to 180.
115+x=180
x=65
so now that you know all the angle measures, you also know that all angles of a triangle add up to 180.
65+3x+19+5x=180
combine like terms:
8x+84=180
subtract 84 from both sides:
8x=96
divide by 8 on both sides
x=12

A blueprint shows an apartment with an area of 15 inches. If the blueprint's scale is 1 inch : 8 feet, what will the actual square footage be?
Pleas help, TYSM ;)
The actual square footage of the apartment based on the blueprint's scale would be 960 square foot.
What is the area of the actual apartment?
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
Scale of the drawing = original dimensions / dimensions of the scale drawing
The area of the building = length x width
Area of actual building = 15 x (length x 8) + (width x 8) = 960
