Answer:
70% in favor of building a new playground
3500 (in favor) + 1500 (against it) = 5000 (total number votes)
3500 (in favor) 1500 (against it)
------------------- = 0.7 / 70% ------------------- =0.3 / 30%
5000 (total) 5000 (total)

Answer:
c. 45.34ft
Step-by-step explanation:
When leg one of the triangle is 15ft and leg two is 17 ft you would take 17^2 + 15^2 and then you find the square root of that (514) to get the hypotenuse of the triangle. After that you multiply by two to account for the 2/2 sqaure foot per each unit

A math professor notices that scores from a recent exam are normally distributed with a mean of 61 and a standard deviation of 8. Answer the following questions using integer values.
(a) What score do 25% of the students exam scores fall below?
And, the professor decides to grade on a curve. If he wants .15% of the students to get an A, what is the minimum score required.
I have tried a "calculator" I found online and the answers it provided gave me 50% credit and I don't know which answer is correct as I don't know how to do the actual calculation.
I would appreciate referral to any valid resources as it has been many, many years since I took a math class.
(b) Suppose the professor decides to grade on a curve. If the professor wants 0.15% of the students to get an A, what is the minimum score for an A?
Answer:
a) 25% of the students exam scores fall below 55.6.
b) The minimum score for an A is 84.68.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 61 and a standard deviation of 8.
This means that [tex]\mu = 61, \sigma = 8[/tex]
(a) What score do 25% of the students exam scores fall below?
Below the 25th percentile, which is X when Z has a p-value of 0.25, that is, X when Z = -0.675.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.675 = \frac{X - 61}{8}[/tex]
[tex]X - 61 = -0.675*8[/tex]
[tex]X = 55.6[/tex]
25% of the students exam scores fall below 55.6.
(b) Suppose the professor decides to grade on a curve. If the professor wants 0.15% of the students to get an A, what is the minimum score for an A?
This is the 100 - 0.15 = 99.85th percentile, which is X when Z has a p-value of 0.9985. So X when Z = 2.96.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2.96 = \frac{X - 61}{8}[/tex]
[tex]X - 61 = 2.96*8[/tex]
[tex]X = 84.68[/tex]
The minimum score for an A is 84.68.

PLEASE DONT SEND LINKS OR I WILL REPORT! Emily buys meat for a charity event in her community. Chicken costs 4 AED per kg and beef burger 3 AED per kg. How much will she spend on 3.6 kg of chicken and 2.2 kg of beef burger?
Answer:
21 AED
Step-by-step explanation:
W know the cost of each kind of meat
Chicken = 4 AED
Beef = 3 AED
We also know how much of each we will be buying
Chicken = 3.6 kg
Beef = 2.2 kg
Multiply each price of meat by its respective weight, then add the products together for you final answer.
4(3.6) + 3(2.2) = 21
Which of the following is the correct point-slope equation for the line that passes through the point (2, -5) and is parallel to the line given by y = -4x + 25?
Answer:
(-4 - (-2))/(2 - (-2)) = -2/4 = -1/2
Step-by-step explanation:
Pick either point.
y - (-4) = (-1/2)(x - 2)
y + 4 = (-1/2)x + 1
y = (-1/2)x - 3

Answer:
b
Step-by-step explanation:
Evaluate the expression for b = 7
6b + 8 – 5b
Answer:
For b = 7, the expression equals 15.
Step-by-step explanation:
6b + 8 - 5b
Substitute the variable b = 7.
6(7) + 8 - 5(7)
Multiply.

15.
Answer:
15
Step-by-step explanation:
6 × 7 = 42
5 × 7 = 35
42 + 8 - 35 = 15
Move words to the blanks to make the sentence true. Volume can be measured by counting the number of unit In a figure. cubes squares two-dimensional three-dimensional
Volume can be measured by counting the number of unit cubic in a
three-dimensional figure.
what is Volume?The amount of space occupied by a three-dimensional figure as measured in cubic units.
Volume is the three- dimensional property, its basic units is always in cube.
Volume generally told us how much capacity can handle which we express it with the help of cubic units.
Volume doesn't wok on two dimensional bodies as well as the square is used for finding the area of the figure.
Thus, Volume can be measured by counting the number of unit cubic in a
three-dimensional figure.

Neil Down is doing some remodeling and needs to cut a triangular piece of wood such that the diagonal is 10 feet long, and the sides of the triangle are in a ratio 3:4. How long should each side be?
Answer:
6 and 8
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
Given this,
(3x)² + (4x)² = 10²
9x² + 16x² = 100
25x² = 100
Divide both sides by 25
x² = 4
x = 2
Substitute this into 3x and 4x.
3x = 3 * 2 = 6
4x = 4 * 2 = 8
Thus, the answer is 6 and 8

the following box plot shows the number of years during which 20 schools have participated in an inter-school swimming meet at least how many schools have participated for 6 years or more?
A: 4
B: 5
C: 10
D: 11
Answer:
4 schools
Step-by-step explanation:
Based on the box plot you have given above, the answer would be 20% of the total schools participated for 6 years or more. This is because the part of the box plot wherein it hits 6 years and above is 20%. Thus, if there are 20 schools, then the 20% of it would be 4. In conclusion, there are 4 schools that participated for 6 years or more.
