Answer: a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression
Step-by-step explanation:
for example
10 x 10 = 100
to simplify this you put a small 2 on the top right corner of the number 10
Least to greatest
1/4, 1/2, 2/3, 3/4
to check your work divide each of the fractions to see their decimals and that will determine which one is greater
Answer:
778
Step-by-step explanation:
We have the length of stay as X
X~N (9,(2.4))
The sample is given as n = 1000
P(7<x<14) is what we are trying to get
P(7-9/2.4 < x-9/2.4 < 14-9/2.4)
= P(-0.83<z<2.08)
P(z<2.08)-p(z<-0.83)
When we go to the z table,
0.981-0.0203
= 0.778
0.778x1000
= 778
So in conclusion, 778 of these guests can be expected to stay between 7 and 14 days.
Answer:
-4 and -16
Step-by-step explanation:
Let x = first number
Let y = second number
Given:
- The two numbers multiply to 64
⇒ xy = 64
Given:
- The two numbers add to -20
⇒ x + y = -20
Rewrite x + y = -20 to make x the subject:
⇒ x = -20 - y
Substitute into xy = 64 and solve for y:
⇒ (-20 - y)y = 64
⇒ -20y - y² = 64
⇒ y² + 20y + 64 = 0
⇒ (y + 4)(y + 16) = 0
⇒ y = -4, y = -16
As x + y = -20
If y = -4 then x = -16
If y = -16 then x = -4
Therefore, the two numbers are -4 and -16
