You live on a triangular piece of land with a base of 121 yards and a height of 80 yards. One acre of land is equal to 4840 square yards. Find the area of your piece of land in acres.

Step-by-step explanation:

1.

[tex]a = \frac{1}{2} b \times h \\ \frac{1}{2} \times 8 \times 7 \\ a = 4 \times 7 = 28 {cm}^{2} [/tex]

2.

[tex]a = \frac{1}{2} b \times h \\ a = \frac{1}{2} \times 10 \times 10 \\ a = 10 \times 5 = 50 {ft}^{2} [/tex]

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

9514 1404 393

Answer:

  4.41

Step-by-step explanation:

The sides of interest in this right triangle are the hypotenuse and the side adjacent to the given angle. The relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

  cos(25°) = 4/AB

Multiplying by AB and dividing by cos(25°), we get ...

  AB = 4/cos(25°)

  AB ≈ 4.41 . . . . units

Answer:

102.35

8.5 is the diameter and we need the radius which is 4.25. 4.25 ^ 3 is 76.75625 and times that by 4 gives us 307.0625 and divide that by 3 gives me 102.35 rounded to the nearest hundrenth

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.

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

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.

Answer:

For b = 7, the expression equals 15.
