Answer:

Last one

Step-by-step explanation:

Let the number be q

22 less than the number: q - 22

Is 24

q - 22 = 24

q = 24 + 22

q = 46

Answer:

Step-by-step explanation:

We need to convert these words into mathematical expressions:

- "Twenty-two less than a number"; "less than" indicates that we need to use subtraction, and since it's "twenty-two less than", we have: -22. Let's say the "number" is q. Then, we have -22 of q, which is q - 22.

- "is twenty-four"; "is" in math always means "equal", so we need an equal sign with 24 next to it: = 24

Put this altogether:

q - 22 = 24

The answer is thus D.

Answer:

´The variance is 10000

Step-by-step explanation:

The variance is defined as the square of standard deviation, consequently it is as follows:

σ^2= $100^{2}$

σ^2=10000

Answer:

37.68cm

Step-by-step explanation:

C = 2 $\pi$ r

C = circumference

$\pi$ = the constant pi (3.14)

r = radius of the circle (6cm)

d = diameter of the circle (12cm)

d = 2r

C = 2 · 3.14 · 6

C = 37.68cm

The graph below shows the distance, y, in miles, of a bird from its nest for a certain amount of time, x, in minutes:

Montano1993 [528]

Answer:

$0.2$ miles per minute represents the speed of the bird and 3 miles represents the original distance of the bird from its nest.

Step-by-step explanation:

As there is no graph mentioned here but the information are quite sufficient to answer the question.

We have points $(0,3), (5,4),(10,5)...$

From these points we can find the slope of the line .

From point slope formula $y-y_1=m(x-x_1)$

And assigning $(x,y) (0,3)$ and $(x_1,y_1) (5,4)$

$m=\frac{y_1-y}{x_1-x} =\frac{4-3}{5-0} =\frac{1}{5}=0.2$

This slope is also the speed of the bird which is $0.2\ miles\ per\ minute.$

As by plugging the values of any coordinate point we can confirm this.

Lets put $(10,5)$ , y-axis is the distance so in $10$ minutes the the distance covered by the bird must be equal to to y-axis value which is $5$ miles.
