Find the missing side length.
Assume that all intersecting sides meet at right angles.
Be sure to include the correct unit in your answer.
?
Answer:
9ft
Step-by-step explanation:
14 ft (top) - 5ft (bottom) = missing side (which is 9ft)
Answer:
9ft
Step-by-step explanation:
suppose that the side of 7ft was dragged to the right till it meets the side of 4ft
and the unknown side was dragged downwards till it meets the side of 5ft
Then, also considering that all angles are right angles, this structure becomes a square.
So the answer is 14ft - 5ft = 9ft

To the nearest foot, what amount of fencing is needed to surround the perimeter of the flower bed? 17 feet 33 feet 40 feet 50 feet.
We have two flower beds in this example, the first has a perimeter of 100 feet, and the second has a perimeter of 180 feet
The total is 280 feet
Perimeter of RectangleGiven Data
Dimension of the first flower bed
Length = 17 feet
Width = 33 feet
Perimeter = 2L + 2W
Perimeter = 2*17 + 2*33
Perimeter = 34 + 66
Perimeter = 100 feet
Dimension of the second flower bed
Length = 40 feet
Width = 50 feet
Perimeter = 2L + 2W
Perimeter = 2*40 + 2*50
Perimeter = 80 + 100
Perimeter = 180 feet
The total length will be 100+180 = 280 feet

Brianna is going to invest in an account paying an interest rate of 5.2% compounded continuously. How much would Brianna need to invest, to the nearest dollar, for the value of the account to reach $134,000 in 6 years?
Your answer would be 98086.
The value of money Brianna need to invest is,
⇒ P = $99,259
What is Simple interest?A quick and easy method of calculating the interest charge on a loan is called a Simple interest.
Given that;
Brianna is going to invest in an account paying an interest rate of 5.2% compounded continuously.
Here, We have;
Final amount (A) = $134,000
Time (n) = 6 years
Rate (r) = 5.2%
We know that;
⇒ Amount = P (1 + r)ⁿ
Substitute the values we get;
⇒ 134,000 = P (1 + 0.052)⁶
⇒ 134,000 = P (1.052)⁶
⇒ P = 134,000 / 1.35
⇒ P = $99,259
Thus, The value of money Brianna need to invest is,
⇒ P = $99,259

The posted speed limit along Elm Street is 25 mph. Homeowners living on Elm Street claim that the
average speed of automobiles traveling on Elm Street is greater than the posted limit of 25 mph and plan to
investigate their claim by measuring the speed of 20 randomly selected cars. If the data support the claim,
the residents plan to ask the city council for more police patrol along Elm Street. Here are the speeds (in
mph) of the 20 cars:
26. 2 22. 9 28. 8 29. 0 24. 8
24. 7 24. 0 24. 4 25. 2 31. 1
25. 6 21. 6 27. 4 25. 6 26. 4
23. 7 28. 2 24. 1 26. 7 26. 8
(a) Is there convincing evidence at the a = 0. 05 significance level that the true mean speed of all cars
traveling on Elm Street is more than 25 mph?
(b) Referring to your conclusion, what type of error may have been made? Describe the error in the
context of this study
The sample of the speeds of 20 cars and at a 0.05 confidence level, we
have;
(a) There is not enough convincing evidence to suggest that the true mean speed of all cars travelling on Elm Street is more than 25 mph
(b) Type II error
What are the process to test the hypothesis?(a) Based on the given data, using MS Excel, we have;
The sample size, n = 20
The mean, [tex]\overline x[/tex] = 25.86
The standard deviation of the sample, s = 2.284
The null hypothesis, H₀; [tex]\overline x[/tex] = 25 mph
Alternative hypothesis, Hₐ; [tex]\overline x[/tex] > 25 mph
Given that the sample size is less than 30, the t-test is used, and the t-score is found as follows;
[tex]t= \mathbf{\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}}[/tex]
Which gives;
[tex]t=\dfrac{25.86-25 }{\dfrac{2.284}{\sqrt{20}}} \approx \mathbf{1.684}[/tex]
Using a graphing calculator, we have;
The probability ≈ 0.054
The critical-t ≈ 1.729
Given that the probability is larger than the significance level, we fail to
reject the null hypothesis.
There is not enough convincing statistical evidence to conclude that the
true mean of all cars travelling on Elm Street is more than 25 mph.
(b) The type of error is Type II error, given that there is a possibility that
the null hypothesis is failed to be rejected when it is actually false.
Given that the sample size is less than 30, it may be insufficient for the
Central Limit Theorem to be in effect.

The graph of an exponential model in the form y = a ⋅ bx passes through the points (3, 5) and (4, 10). Which point is also on the graph?
Answer:
The answer is D
Step-by-step explanation:
First, find a and b from the given points.
y = abx
5 = ab3
10 = ab4
b = 10/5 = 2
5 = a(23)
a = 5/8
y = (5/8) 2x
Test the choices:
x = 2 ⇒ y = 5/2
This rules out (a) and (b).
x = 5 ⇒ y = 20

Triangle OPQ is similar to triangle RST. Find the measure of side ST. Round your answer to the nearest tenth if necessary
Given that triangles OPQ and RST are similar triangles, the measure of side ST is: 75.3.
What are Similar Triangles?The ratio of the corresponding sides of two similar triangles are always equal, meaning the sides are proportional to each other.
Given:
OP = 17ST = 31PQ = 7Since Triangle OPQ is similar to triangle RST, therefore:
RS/OP = ST/PQ
