Answer:

126 was removed.

Step-by-step explanation:

The total before division took place was

Total = mean * 14

mean = 49

Total = 49 * 14

Total = 685

Now you subtract x from the total

685 - x

And divide by 13 [one number is missing]

(685 - x)/13

and the result = 43

(685 - x ) / 13 = 43                Multiply both sides by 13

685 - x  = 43 * 13

685 - x = 559                       Subtract 685 from both sides

- x = - 126                             Multiply by - 1

x = 126

An integer is chosen between 0 and 100. What is the probability that it is divisible by 7?
IgorC [24]
Assuming 0 and 100 are included in the possible choices:

There are \left\lfloor\dfrac{101}7\right\rfloor=14 multiples of 7 between 0 and 100, so there is a \dfrac{14}{101}\approx0.1386 probability of choosing a multiple of 7.

Mel slides down waterslide A, and Victor slides down waterslide B. After 2 seconds, Mel was 50 feet in the air, and after 5 seco
s2008m [1.1K]

Answer:

Mel was descending at 5 feet per second and Victor was descending at 3.33 feet per second, thus Mel was descending faster.

Since after 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air, while after 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air, to determine who was descending at a faster average rate and what is Mel's rate of change, the following calculations must be performed:

You must subtract the difference between the two times for each person, and check which is the highest rate between the two.

Mel =

(50 - 35) / (5 - 2) = X

15/3 = X

5 = X

Victor =

(60 - 50) / (4 - 1) = X

10/3 = X

3.33 = X

Therefore, Mel was descending at 5 feet per second and Victor was descending at 3.33 feet per second, thus Mel was descending faster.
