Which equation is true?

enot [183]

Lets solve all of these:-

#1

√361 = 361 · 2

?
√361 = 361 · 2
√361 = 19
361 · 2 = 722

19 ≠ 722
So this equation is not true

#2:-

√361 = 19²

?
√361 = 19²
√361= 19
19² = 19 · 19 = 361

19 ≠ 361
So this equation is not true

√361 = 361 ÷ 2

?
√361 = 361 ÷ 2
√361 = 19
361 ÷ 2 = 180.5

√361 ≠ 361 ÷ 2
So this equation is not true

√361 = √19²
√361 = 19
√19² = 19

19 = 19

SO the last one is right. Hope I helped ya!! xD

Rose writes down all of her math quiz scores. Her math scores are 98,78,84, and 96. What is the mean of her math quiz scores?

KATRIN_1 [288]

Answer:

Step-by-step explanation:

Hi, there to find the mean

you need add the numbers and count how many numbers are there and divide

In this case 98+78+84+96= 356

Now we will count

there are 4 numbers

$\frac{356}{4}$ = 89

Your mean will be 89

If you ever have trouble with mean remember this

Mean $\frac{SumofDataPoints}{NumberofDataPoints }$

well it is supposed to be:

Sum of Data Points/Number of Data Points
