sin 60 sin 80

---------- = ---------------

7 x

Using cross products

x sin 60 = 7 sin 80

x = 7 sin 80 / sin 60

x=7.96010

To the nearest hundredth

x = 7.96

Yuliya22 [10]

Answer:

88/345 which is 0.2551

Step-by-step explanation:

Since we are picking 2 athletes randomly and without replacement.

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

Probability of basketball player (this is after 1 volleyball player has already been picked). We have 45 players left. = 22/45

probability of picking one volleyball player and one basketball player

p(volleyball player and basketball player)

(12/23) x (22/45)

= 88/345

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:

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
