How tall is the monument?
Answer:
43.125
Step-by-step explanation:
From trigonometry;
Tan87.4 =height of monument / 25
Height of monument = 25 * Tan 87.4
= 25 * 1.525
=38.125 ft
There is an extra substention of 5ft we add that
38.125 + 5 = 43.125 ft

Answer:
The answer is 4
Step-by-step explanation:
Answer: 4
Step-by-step explanation:
A correlation coefficient a numerical measure of change of two variables, but it is often a sample from a data set. Considering there is no change between our x and y variables that align in our change, the correlation coefficient I thought it would be is 0, but answering C.4 got an 100% on the Edge Test.

Answer:
11 because 10x2=20 and the 220 divided by 20 =11
Step-by-step explanation:
Let the speed of the train going from Boston to New York = X
Let the distance from Boston to when the trains meet = Y
The distance to New York when they meet would be 220 - Y
The Boston to New York train would be: Y = (2X-10)*2
New York to Boston train would be : 220 -Y = 2X
Using substitution:
220-(2X-10)*2 = 2X
Simplify the left side:
220 - 4X+20 = 2X
Add 4x to both sides and combine like terms:
240 = 6X
Divide both sides by 6:
x = 40
Now find distance from Boston by replacing x with 40"
Y = (2(40)-10)*2
Y = 160 -20
Y = 140 miles

This scatter plot shows the data collected by measuring the amount of water in a tank every 15 minutes. What is the equation of the line of best fit?
A: y= -4/3x+120
B: 4/2x+120
C: -3/4x+60
D: -4/3x-60
E: -3/4x-120
Answer:
A: y= -4/3x+120
Step-by-step explanation:
The blue line on the plot has a y-intercept of +120, matching choices A and B only.
The line has a negative slope, matching choice A. If you count grid squares, you find the slope is -40/30 = -4/3, also matching choice A.
Answer:
A: y= -4/3x+120
A cylinder has a volume of 315 pi cubic meters and a height of 21 meters. What is the area of the base?
Answer:
The area of base is 47.1 m² or 15π m².
Step-by-step explanation:
Given that the formula of volume of cylinder is V = πr²h where πr² is the base area of cylinder so you have to substitute the following values into the formula :
[tex]v = \pi \times {r}^{2} \times h[/tex]
Let v = 315π,
Let h = 21,
[tex]315\pi = \pi {r}^{2} \times 21[/tex]
[tex]\pi {r}^{2} = 315\pi \div 21[/tex]
[tex]\pi {r}^{2} = 15\pi[/tex]
[tex]base \: area = 15\pi \: {m}^{2} [/tex]
[tex]base \: area = 47.1 \: {m}^{2} (3s.f)[/tex]

The outlier of a data set causes the _____(mean/median) to be greater than the ______(mean/median) when the outlier is in the upper part of the data set.
Answer:
Mean, Median
Step-by-step explanation:
Outliers affect the mean because it is not resistant to outliers. They will affect the sum and therefore the mean.
The solution is, Mean, Median.
i.e. The outlier of a data set causes the Mean (mean/median) to be greater than the Median (mean/median) when the outlier is in the upper part of the data set.
What is median?In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.
here, we have,
we know that,
Outliers affect the mean because it is not resistant to outliers.
They will affect the sum and therefore the mean.
so, we get,
The outlier of a data set causes the Mean (mean/median) to be greater than the Median (mean/median) when the outlier is in the upper part of the data set.
hence, The solution is, Mean, and, Median.

Y is directly proportional to x when x=600 y=10 find a formula for y in terms of x
Answer:
y = x/60
Step-by-step explanation:
y = kx
k = y / x = 10/600 = 1/60
y = x/60
[tex]y[/tex] is directly proportional to [tex]x[/tex] when [tex]x=600[/tex] and [tex]y=10[/tex] then the formula for [tex]y[/tex] in terms of [tex]x[/tex] is given as [tex]y=\frac{1}{60} x[/tex] .
What is directly proportional?We say that, [tex]y[/tex] and [tex]x[/tex] are directly proportional, if [tex]\frac{y}{x} =k[/tex] or [tex]y=kx[/tex].
So,
According to the question;
[tex]x=600[/tex]
[tex]y=10[/tex]
From the above statement;
[tex]\frac{10}{600} =k[/tex]
[tex]k = \frac{1}{60}[/tex] ,
So,
[tex]y[/tex] in terms of [tex]x[/tex] is given by,
[tex]y=\frac{1}{60} x[/tex]
Hence, we can say that [tex]y[/tex] is directly proportional to [tex]x[/tex] when [tex]x=600[/tex] and [tex]y=10[/tex] then the formula for [tex]y[/tex] in terms of [tex]x[/tex] is given as [tex]y=\frac{1}{60} x[/tex] .

The Second choose is 96/216/60

If you don't consider how the wood might be cut, or how the tray might be assembled, you can look only at the area requirements.
A tray that is 10.5 inches square will have an area of ...
(10.5 in)^2 = 110.25 in^2
That base will have a perimeter that is 4×10.5 in = 42 in. If the perimeter piece(s) are 2 inches high, the area of the sides of the tray will be ...
(42 in)(2 in) = 84 in^2
Then the total area of wood required for the proposed tray is ...
110.25 in^2 +84 in^2 = 194.25 in^2
__
The area of the wood Stephan has is ...
A = LW = (18 in)(12 in) = 216 in^2 . . . . . . more than required
__
Stephan does have enough wood to make the tray, because he has 216 square inches, which is more than he needs to make the tray, 194.25 square inches.

Phil is paid £240 per week.
Each week he saves one-quarter of his pay.
B) He is saving for a new bike that costs £349.
How many weeks does it take to save enough to buy the bike?
Phil would need to save for at least 6 weeks to have enough money to buy the bike.
Phil saves one-quarter of his pay each week, which is:
1/4 x £240 = £60
Let's assume it takes him n weeks to save enough to buy the bike. Then, the amount he saves in n weeks is:
n x £60 = £349
We can solve for n by dividing both sides by £60:
n = £349 / £60
n ≈ 5.82
Since we can't have a fraction of a week, Phil would need to save for 6 weeks to have enough money to buy the bike.

Find the range, variance, and standard deviation for the given sample data. Include appropriate units in the results. Listed below are the measured radiation absorption rates (in W/kg) corresponding to various cell phone models. If one of each model is measured for radiation and the results are used to find the measures of variation, are the results typical of the population of cell phones that are in use? 0.83 1.39 1.39 1.03 0.66 1.26 1.39 1.18 1.41 1.19 1.15
Answer:
[tex] Range =1.41-0.66 = 0.75[/tex]
[tex] \bar X = 1.171 W/Kg[/tex]
[tex] s^2 = 0.0607[/tex]
And taking the square root we got the sample deviation:
[tex] s = \sqrt{0.0607}= 0.246 W/kg[/tex]
Step-by-step explanation:
For this case we have the following datset given:
0.83 1.39 1.39 1.03 0.66 1.26 1.39 1.18 1.41 1.19 1.15
We need to find the range, and the range is defined by:
[tex] Range = Max -Min[/tex]
And replacinng we got:
[tex] Range =1.41-0.66 = 0.75[/tex]
Then we can find the sample variance, but firt we need to find the sample mean with this formula:
[tex]\bar X = \frac{\sum_{i=1}^n X_i}{n}[/tex]
And replacing we got:
[tex] \bar X = 1.171 W/Kg[/tex]
Now we can find the sample variance with this formula:
[tex] s^2 = \frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}[/tex]
And replacing we got:
[tex] s^2 = 0.0607[/tex]
And taking the square root we got the sample deviation:
[tex] s = \sqrt{0.0607}= 0.246 W/kg[/tex]
