15.<br> How many values are in the data set whose histogram is shown below?
Orlov [11]

The total values in the dataset is 24 values

From the given histogram, to get the number of values in the dataset, we will have to trace each bar to the y-axis and then take the sum.

  • For the black bar, the total values of the dataset will be 11 + 2 = 13
  • For the white bar, the value of the data st will be 3
  • For the grey bar, the total values of the dataset will be 1 + 2 = 3
  • For the ask bar,  the total values of the dataset will be 2 + 3 = 5

The total values of the dataset = 13 + 3 + 3 + 5

The total values of the dataset = 24 values

Hence the total values in the dataset is 24 values

Monica runs on a treadmill at an average speed of 7.5 miles per hour for 15 minutes. If, the next day, she runs the same distanc
telo118 [61]

Answer:

Option 2: 14.06 minutes

Step-by-step explanation:

For the first scenario, we will convert the minutes into hours first to get all the quantities in same unit

So,

15 minutes = 1/4 hours = 0.25 hours

Speed = 7.5 miles per hour

Now using the speed, distance and time formula

Speed = distance/time

Speed = \frac{distance}{time}

7.5 = \frac{distance}{0.25}

7.5 * 0.25 = Distance

Distance = 1.875 miles

So the distance for 1st day is 1.875 miles.

For next day

Speed = 8 miles per hour

Distance = 1.875

So,

speed = \frac{distance}{time}

8 = \frac{1.875}{time}

time = \frac{1.875}{8}

time = 0.234375 hours

Converting the hours into minutes will give

0.234375 * 60 min =  14.0625 minutes

Rounding off to two decimals = 14.06 min

So 2nd option is correct..

The length of the hypotenuse of a right triangle is 137 units. The length of one leg of the triangle is 105. Gina wrote the foll
OLga [1]
A^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 137^2 - 105^2
b^2 = 18769 - 11025
b^2 = 7744
b = sqrt 7744
b = 88

Gina's step is not correct... the length of the unknown leg is not 7744, it is the sqrt of 7744, which is 88
