Answer:
x= 45 degree
Step-by-step explanation:
as this is a right angle triangle and a line is bisecting angle 90 degree from the mid point so angle is 90/2 = 45 degree .

To test the durability of cell phone screens, phones are dropped from a height of 1 meter until they break. A random sample of 40 phones was selected from each of two manufacturers. The phones in the samples were dropped until the screens broke. The difference in the mean number of drops was recorded and used to construct the 90 percent confidence interval (0.46,1.82)
to estimate the population difference in means.
Consider the sampling procedure taking place repeatedly. Each time samples are selected, the phones are dropped and the statistics are used to construct a 90 percent confidence interval for the difference in means. Which of the following statements is a correct interpretation of the interval?
Answer:
See below.
Step-by-step explanation:
I see there are no answer choices you've provided, but in order to interpret a confidence interval correctly, you might say something like "We are 90% confident that the true difference in the mean number of drops is contained within the interval".

Answer:
3150 ft³Step-by-step explanation:
Since this is a rectangular prism, we need to do length × width × height to find the volume. Now despite the shape being tilted at an angle, nothing is different.
So we can see that the length is 25, the width is 18 and the height is 7
Rewrite the formula for volume replacing variables
25 × 18 × 7
Now solve.
25 × 18 = 450
450 × 7 = 3150
Now before we finalize our answer, there are two more things we need to do.
We need to add the measurement unit which is feet or ft
We also need to add ³ since it is volume
Add both of these to the end
3150 ft³ is your final answer
The area of a rectangular field is 99m2. The length of one side is
11m. The farmer needs to know its perimeter to work out how
much fencing will be needed? Help
Answer:
40 m
Step-by-step explanation:
The length of another side
= 99÷11
= 9 m
The perimeter of the field
= 9×2 + 11×2
= 40 m
Answer:
40 m
Step-by-step explanation:
Hi there!
What we know:
The field is rectangularA = 99 m²Length of one side = 11 m1) Find the length of the other side
Plug all the given information into the area formula for a rectangle:
[tex]A=lw[/tex] where A is the area, l is the length and w is the width
[tex]99=11w[/tex]
Divide both sides by 11 to isolate w
[tex]\frac{99}{11} = \frac{11w}{11} \\9=w[/tex]
Therefore, the width of the field is 9 m.
2) Find the perimeter of the field
[tex]P=2(l+w)[/tex] where l is the length and w is the width
Plug in the length (11 m) and the width (9 m)
[tex]P=2(11+9)\\P=2(20)\\P=40[/tex]
Therefore, the perimeter of the field is 40 m.
I hope this helps!

What’s the growth factor of f(x)=500(1+.12)^x
Answer:
12%
Step-by-step explanation:
For every value of x, the initial value is increased by 1+0.12 = 100% + 12%.
meaning we are adding 12% for every value of x
Given f(x) = 1/3(9 + x), what is the value of f(-12)?

14. height = volume/ ( length x width)
Height = 224/ ( 2x8)
Height = 224/16
Height = 14 inches.
15. height = volume/ area of the top(circle)
Area of top = pix r^2 = 3.14 x 4 = 12.56 square inches.
Height = 62.8/12.56 = 5 inches
16. Volume/ height = area of top(circle)
169.56/ 6 = 28.26 square inches
Area = pi x r^2
28.26 = 3.14 x r^2
Divide both sides by 3.14
R^2 = 28.26/3.14 = 9
Take the square root of both sides
R = sqrt(9)
R = 3
Radius = 3 inches

North carolina has 12 less electoral votes than florida. Write and solve a subtraction equation if the total number of votes for both states is 64
Step-by-step explanation:
Given
North Carolina has 12 fewer electoral votes than Florida
The total number of votes is 64
Suppose Florida receives [tex]x[/tex] votes
thus, votes received by North Carolina is [tex]y[/tex]
So, we can write
[tex]\Rightarrow x-y=12\quad \ldots(i)[/tex]
[tex]\Rightarrow x+y=64\quad \ldots(ii)[/tex]
Solving the above equations we get
[tex]x=38,y=26[/tex]

A car with an initial cost of $33,000 is decreasing in value at a rate of 7% each year. Write the exponential decay function to determine when the value of the car will be $15,000 to the nearest year
Answer:
n= 11.65 years
Step-by-step explanation:
Giving the following information:
Present Value (PV)= $33,000
Future Value (FV)= $15,000
Decrease rate (d)= 7%
To calculate the number of years it will take to reach $15,000; we need to use the following formula:
n= ln(FV/PV) / ln(1+d)
n= ln(15,000/33,000) / ln(1.07)
n= 11.65 years
