7 0

Answer:

21 and 8, respectively

Step-by-step explanation:

7/10 of 30 is (7 x 30)/10 = 210/10 = 21

Alternatively, 7/10 = (3 x 7)/30, since 30 = 3 x 10

4/5 of 10 is (4 x 10)/5 = 40/5 = 8

Alternatively, 4/5 = (2 x 4)/10, since 10 = 2 x 5

At 2:00pm a car's speedometer reads 20mph, and at 2:10pm it reads 30mph.
Dmitry [639]

Over this 10-minute interval, the car's average acceleration is

\dfrac{30\,\mathrm{mph}-20\,\mathrm{mph}}{10\,\mathrm{min}}=\dfrac{10\,\mathrm{mph}}{\frac16\,\mathrm h}=60\dfrac{\rm mi}{\mathrm h^2}

The MVT says that at some point during this 10-minute interval, the car must have had an acceleration of 60 mi/h^2.

Five times a number increased by six equals negative two.
melamori03 [73]
To solve this question simply break down the variables and numbers one at a time.

Here the word a number can be used to describe any number so let’s call that a variable x.

Increased would be addition in mathematics.

Next put everything together.

5x + 6 = -2

5x = -8

X = -8/5.

This is the value of x

In one statistics course, students reported studying an average (mean) of 9.92 hours a week, with a standard deviation of 4.54.
quester [9]

Answer:

For the student who is studying 10 hours a week is in the 57.93th percentile.

Step-by-step explanation:

Corresponding z-score for the student who studies 10 hours a week can be calculated by the formula

z=\frac{x-M}{s} where

  • x is the hours student work in a week, which is 10,
  • M is the mean studying hour of the class, which is 9.92,
  • s is the standart deviation which is 4.54

from here we find that z=\frac{10-9.92}{4.54}≈0.2

Corresponding percentile for z=0.2 is 57.93
