Answer I think it's 24/1 because if you solve the equation it's 24.
Step-by-step explanation:
Let

denote the number of minutes spent brushing his teeth, and let

be the mean and

the standard deviation for this distribution.

The z-score corresponding to this probability is approximately

, which means

Next, (note the sign change)

The corresponding z-score is approximately

, so you have

Solving the two equations for

and

, you'll find that the mean is approximately

and the standard deviation is approximately

.
Answer:
#1. 8.27
#2. 36
#3. 22
#4. 7.25
Step-by-step explanation:
#1: 60÷11=5.45 ----> 5.45×16=<u>87.27</u> <This is a non-terminating decimal>
#2: 60÷5= 12 ----> 12×3= <u>36</u>

#3: Games- 35 Won- 14 Lost- 21
In 1 Game Manchester won = 14/35 = 2/5 games in 54 Game Manchester won = 54 x 2/5 games
= 108 / 5
= 21.6
<u>= 22</u>
<u></u>
#4: 6 : 91 ⇒ n : 110
6(110) ⇒ 91(n)
660 ⇒ 91n
660/91 ⇒ n
<u>7.25=n</u>

Step-by-step explanation:
The y coordinate of the vertex is -5.
Answer:
A fair six-sized die is rolled. Find the probability of getting at least a 4.
There are 6 outcomes and three of them are 4, 5 or 6, so the probability of greater than or equal to 4 is 3/6=½.
