Answer:
Step-by-step explanation:
z score= x - mean/standard deviation
1.20= x -100/15
18= x -100
118=x
z score= x - mean/standard deviation
0.5=x-73/4
2=x-73
75= x
Answer:
20 hours
Step-by-step explanation:
10*8*4=320 (volume of the pool)
320/16=20 hours
1st Convert into a top heavy fraction or improper fraction
<h3>
like for example 3 1/2 so you times the 3 by 2 which is 6 and add that one so it will be 7/2</h3><h3>
lets say your adding that to 2 1/2 you convert that which is 5/2 </h3><h3>
5/2 and 7/2 have the same denominator so you add 5 and 7=12 12/2 and 2 goes into 12 6x so it is just 6 </h3><h3>
THIS IS AN EXAMPLE</h3><h3>
TO REGROUP THEM </h3><h3>
Lets say its </h3><h2>21/4</h2><h3>YOU DIVIDE 21 BY 4 WHICH IS 5 WITH AN REMAINDER OF 1 SO YOU DO THAT 5 AS A BIG NUMBER AND THAT ONE GES ABOVE THE FOR LIKE 5

</h3><h3>SO I TRIED :)</h3>
Answer: x = ± 1.68
Step-by-step explanation:
7x^4 = 56
x^4 = 56/7
x^4 = 8
Let a = x²
(x²)² = 8
(a)² = 8
a = ± √8
Now,
a = -√8
x² = -√8 has no real solution.
Taking +√8
a = √8
x² = √8
x = ± √(√8))
x = ± 1.68
