How do i calculate the first quartile and the third quartile??? <br> !!!please help!!!
diamong [38]

Answer: The Median: 78, The First Quartile: 63, and The Third Quartile: 99

Step-by-step explanation: Ok, so let's put the data set from least to greatest....

(63, 63, 76,) (77, 79,) (84, 99, 99)

First Quartile              Third Quartile

First, let's find the median, since you made a little mistake...

77 + 79 = 156

156 ÷ 2 = 78

The median is 78!

Now, let's determine the first quartile and the third quartile.

For the the first quartile/third quartile it'll be the middle number, if it's even we'll do the same extra step just like we'll do for the median. In this case it's not even therefore...

First Quartile: 63

Third Quartile: 99

I hope this helps!

I need help plzzzzzzzzzzzzzzzzzzzzzzzz

We can find the value of x through a proportion. Since these two triangles are similar, their sides are in proportion.

4 is to 12 as 5 is to x
Remember to say 12, not 8! 8 is only part of the whole side. We can also simplify 4 is to 12 to 1 is to 3.

1/3 = 5/x
Cross multiply
x = 15
Hope this helps!

Frances solves the inequality 5g≥ 35. She says that 7 is a solution to the inequality. Is Frances correct? Explain
AlekseyPX

Answer:

<u>Step 1:  Divide both sides by 5</u>

<u />5g / 5 \geq  35 / 5

g \geq  7

So... the line underneath the > means that 7 is included.  Therefore, Frances is correct.
