Answer 1
Answer: Given the equation: (km / 3) - 2x = 4, it is essential to isolate x to obtain the expression to solve it. This is done below:

(km / 3) - 2x = 4

Adding 2x to both sides:

(km / 3) - 2x + 2x = 4 + 2x
(km / 3) = 4 + 2x

Subtracting 4 from both sides:

(km / 3) - 4 = 4 + 2x - 4
(km / 3) - 4 = 2x

Dividing 2 from both sides:

[(km / 3) - 4] /2 = 2x /2
[(km / 3) - 4] /2 = x
x = (km / 6) - 2

Simplify if possible

75/100

Answers

(3)/(4)


(75)/(100) simplified is (3)/(4) because we can see that the greatest common divisor for both the numerator and the denomenator, is 25.

75 ÷ 25 = 3
100 ÷ 25 = 4

thus leaving us with (3)/(4)
75/100 would be 1/4 because 4 in 1/4 is how many times you multiply ? to get 100

                    so 4*?=100
25 times 4 equals 100 so now what times 4 equals 75
                     

                    so 25*?=75
25 times 3 is 75 so if that is true then your answer is 3/4-3 out of 4

Which is the volume of a cylinder with a radius of 6 feet and a height of 10 feet? (Use 3.14 for .) A. 1,129.88 cubic feet B. 1,130.40 cubic feet C. 1,130.24 cubic feet D. 1,131.00 cubic feet

Answers

Answer:

B. 1,130.40 cubic feet

Step-by-step explanation:

Volume of a cylinder is

V = pi * r^2h

We know r=6 and h =10 and use 3.14 for pi

V = 3.14 * 6^2 *10

V =3.14*36*10

V = 1130.4 ft^3

3. We will now study probability distributions that can be obtained from the data. (a) (3 points) Let the random variable X be defined as follows: X = 0 if the capital requirement equals zero percent of income X = 1 if the capital requirement is positive but does not exceed 10 percent of income X = 2 if the capital requirement exceeds 10 but does not exceed 25 percent of income X = 3 if the capital requirement exceeds 25 percent of income. Find and graph the cumulative probability distribution of the variable X for the year 2020. (b) (2 points) Using the distribution from exercise 3(a), compute P(1 ≤ X < 3). (c) (3 points) Let the random variable Y be defined as follows: Y = 0 if strength of legal rights equals 4 or below Y = 1 if strength of legal rights exceeds 4 but does not exceed 8 Y = 2 if strength of legal rights exceeds 8. Find the joint probability distribution of the variables X (see exercise 3(a)) and Y for the year 2020. (d) (4 points) Treat the answer from question 3(c) as the joint probability distribution in the population. Using that distribution, what is the correlation between X and Y ?
