During the 14 days 2,744 people Visited a new store. The same number of people Visited the store each day. About how many people
Pie
You just said that "the same number of people visited each day",
so there's no "about" about it.  It has to be an exact number.

Each day,  (2744)/(14) = 196 people visited.

A company manufactures cell phones. In August, a random sample of 125 cell phones was inspected, and 3 phones were found to be d
german

Answer:

192

Step-by-step explanation:

To find how many phones are expected to be defective, we need to represent the values in a fraction.

\dfrac{x}{8000}=\dfrac{3}{125}

x = number of defective phones

Now we can solve this using algebra.

To get the value of x we need to multiply both sides by 8000 to leave x alone.

x=\dfrac{3}{125}(8000)

x=0.024(8000)

x=192

So around 192 cell phones are expected to be defective out of 8000 phones.

The equations of two functions are y=-21x+9 and y=24x+8 which function is changing more quickly? Explain
antoniya [11.8K]

Given:

The equations are

y=-21x+9

y=24x+8

To find:

Which function is changing more quickly.

Solution:

The slope intercept form of a line is

y=mx+b

Where m is slope and b is y-intercept.

On comparing y=-21x+9 with the slope intercept form, we get

m_1=-21

|m_1|=|-21|

|m_1|=21

On comparing y=24x+8 with the slope intercept form, we get

m_2=24

|m_2|=24

Since, |m_1|, it means the absolute rate of change of second function is greater than the first function.

Therefore, the second function is changing more quickly.
