Using cross products

x sin 60 = 7 sin 80

x = 7 sin 80 / sin 60

x=7.96010

Since we are picking 2 athletes randomly and without replacement.

Probability of 1 volleyball player = 24/46 = 12/23

Probability of basketball player (<u>this</u><u> </u><u>is</u><u> </u><u>aft</u><u>er</u><u> </u><u>1</u><u> </u><u>vol</u><u>ley</u><u>ball</u><u> </u><u>play</u><u>er</u><u> </u><u>has</u><u> </u><u>alr</u><u>eady</u><u> </u><u>be</u><u>en</u><u> </u><u>picked</u><u>)</u><u>.</u><u> </u><u>We</u><u> </u><u>hav</u><u>e</u><u> </u><u>4</u><u>5</u><u> </u><u>players</u><u> </u><u>left</u><u>.</u><u> </u><u>=</u><u> </u><u>2</u><u>2</u><u>/</u><u>4</u><u>5</u>

The average of 10 numbers is 85. If the numbers 70 and 76 are removed from the set of numbers, what is the average of the remain
Alexeev081 [22]

Answer:

88

Step-by-step explanation:

From the question:

The average of 10 numbers is 85.

We have to find the total sum for the 10 numbers

Hence: 10 × 85 = 850

If the numbers 70 and 76 are removed from the set of numbers.

This means 10 number is reduced by 2

= 10 - 2 = 8

The total sum of the 8 numbers is

= 850 - (70 + 76)

= 850 - 146

= 704

The average of the remaining numbers is calculated as:

Sum of the 8 numbers/8

= 704/8

= 88.

Therefore, the sum of the remaining numbers is 88
