olga55 [171]

Answer:

Solution given:

angle : 80°

hypotenuse:y=?

opposite=21

we have

Sin 80= $\frac{opposite} {hypotenuse}=\frac{21}{y}$

doing crisscrossed multiplication

we get

y= $\frac{21}{Sin 80°}$

<u>y=21.32</u>

What is the mean of this data set? {14, 7, 2, 8, 3} Enter your answer as a decimal in the box.

Assoli18 [71]

The mean of the data set is 6.8.

Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean.

Given

The data set is 14, 7, 2, 8, 3.

The mean of the data set is given by;

$\rm Mean = \dfrac{Sum \ of \ all \ data}{Number \ of \ data}\\\\Mean =\dfrac{14+7+2+8+3}{5}\\\\Mean = \dfrac{34}{5}\\\\Mean=6.8$

Hence, the mean of the data set is 6.8.

= 5 + 4 - 1 + (-3)

= 5 + 4 - 1 - 3

= 5 + 4 - 4

Mac hine A pops 12,75 ounces of popcorn in 3 minutes. Machine B pops 18 ounces of popcorn in 4minutes. If each machine pops popc

Nataly [62]

yes. Machine A pops 42.5 ounces of popcorn in 10 minutes. Machine B pops 45 ounces of popcorn in 10 minutes. Add the two to get 87.5 ounces. 8 times 9 is 72 which is less than 87.5 ounces
