Question 5 (1 point)
If y varies jointly as x and z and y = 18 when x = 2 and z = 3, find y when x is 5 and z is 6.

Answers

Answer 1

Answer:

y = 90

Step-by-step explanation:

If y varies jointly as x and z, then;

y = kxz

If y = 18 when x = 2 and z = 3

18 = k(2)(3)

18 = 6k

k = 18/6

k = 3

To get y when x = 5 and z = 6

y = kxz

y = 3(5)(6)

y = 15*6

y = 90

Hence the value of y is 90

Three sixth-grade classes raised $25.50, $49.75,
and $37.25 for their classroom libraries. They agreed to
share the money raised equally. What is each class’s equal share?

Answers

Answer:

$37.50

Step-by-step explanation:

They are asking you to find the average and to do that you have to add all the numbers together in a given set then divide that total by the amount of numbers in that set to get your average.

Answer:

The answer is, 37.50

Step-by-step explanation:

Definition of spread out and share:

In statistics, spread refers to a data set's variability, or how the data is spread out and differs from the mean.

The range, quartiles, deciles, and percentiles; the five-number summary; standard deviation, and variance are all examples of spread measures.

According, to the question:

Adding the all the value, 25.50, 49.75,and 37.25

= 25.50+49.75+37.25

= 112.5

To get your average, divide the sum by the number of numbers in the set.

= 112.5/3

= 37.50

The equal share of the class is 37.50.

A bridge connecting two cities separated by a lake has a length of 5927.261 yd. use the table of facts to find the length of the bridge in miles. Round your answer to the nearest tenth.

Answers

Answer:

the length of the bridge in miles is 3.37 miles

Step-by-step explanation:

The computation of the length of the bridge in miles is shown below:

Given that

The length is 5927.261 yard

As we know that

1760 yard = 1 mile

So 1 yard = 1 ÷ 1760 mile

For 5927.261 yard, the miles would be

= 5927.261 ÷ 1760

= 3.37 miles

Hence, the length of the bridge in miles is 3.37 miles
