Answer: 40 degrees

Step-by-step explanation:

A triangle's angles will always add up to 180 degrees. You would solve this problem by either adding up the two angles you already have and then subtracting that answer from 180, or you can do 180-60-80 = 40

The third angle would be 40°

This is because all angles of a triangle add up to 180°

If we know two sides we can figure out the third by adding up the two sides we know and subtracting them from 180°

The final answer when subtracting is 40°

Have a great day!

What is the third quartile, Q3, of the following distribution?

GREYUIT [131]

Answer:

The third quartile is:

$Q_3=29$

Step-by-step explanation:

First organize the data from lowest to highest

4, 5, 10, 12, 14, 16, 18, 20, 21, 21, 22, 22, 24, 26, 29, 29, 33, 34, 43, 44

Notice that we have a quantity of n = 20 data

Use the following formula to calculate the third quartile $Q_3$

For a set of n data organized in the form:

$x_1, x_2, x_3, ..., x_n$

The third quartile is $Q_3$ :

$Q_3=x_{\frac{3}{4}(n+1)}$

With n=20

$Q_3=x_{\frac{3}{4}(20+1)}$

$Q_3=x_{15.75}$

The third quartile is between $x_{15}=29$ and $x_{16}=29$

Then

$Q_3 =x_{15} + 0.75*(x_{16}- x_{15})$

$Q_3 =29 + 0.75*(29- 29)\\\\Q_3 =29$

Answer:

a) 200 yards

Step-by-step explanation:

Difference in the distance = 50 yards

Difference in speed = 8 - 6 = 2 y/s

Time to cover the gap is:

50/2 = 25 seconds

Sandra will run the distance:

25*8 = 200 yards
