Hello, hows your day going?

A telemarketer has 4 hours a day to call people for a survey. It takes 3 seconds to dial the number and each call takes 2 minute

The telemarketer can make 117 calls per day

Solution:

Given that a telemarketer has 4 hours a day to call people for a survey

It takes 3 seconds to dial the number and each call takes 2 minutes

To find: Number of calls made in 1 day

From given statement,

Total number of hours = 4 hours

Convert 4 hours to minutes

1 hour = 60 minutes

4 hours = 4 x 60 = 240 minutes

Time taken to dial the number = 3 seconds

Convert 3 seconds to minutes

Use the following conversion factor

$1 \text{ second } = \frac{1}{60} \text{ minute }$

$3 \text{ second } = 3 \times \frac{1}{60} \text{ minute } = 0.05 \text{ minute }$

Thus,

Time taken to dial the number = 0.05 minute

Time taken for call = 2 minutes

Total number of time = 240 minutes

Let "x" be the number of calls made per day

Total number of time = x(Time taken to dial the number + Time taken for call)

Therefore, we get

240 minutes = x(0.05 minute + 2 minute)

240 = x(2.05)

2.05x = 240

$x = \frac{240}{2.05}$

x = 117

Thus 117 calls can be per day

Find the value of z?

lorasvet [3.4K]

Answer:

110°

Step-by-step explanation:

I forgot the correct terminology but it's like co-interior angles add up to 180°, so z = 110°

Write an equation in point-slope form of the line that passes through the points

Aleksandr-060686 [28]

Hello!

Step-by-step explanation:

Slope: $\frac{Y^2-Y^1}{X^2-X^1}=\frac{rise}{run}$

$\frac{(-2)-(-4)=-2+4=2}{3-2=1}=\frac{2}{1}=2$

Answer: 2

Slope is 2.

Hope this helps!

Thanks!

2. Cameron worked 8 hours at the coffee shop. He earned the same amount in tips and wages each hour. At the end of his shift, Ca

Elden [556K]

Answer:

$\$12$

Step-by-step explanation:

Let money earned in tips every hour is $x$

Money earned in wages every hour is $y$

Number of hours in the shift is 8

Money earned in 8 hours in tips is $32

$8x=32\\\Rightarrow x=\dfrac{32}{8}\\\Rightarrow x=4$

Money earned in 8 hours in wages is $64

$8y=64\\\Rightarrow y=\dfrac{64}{8}\\\Rightarrow y=8$

Money earned each hour is $x+y=4+8=\$12$ .

For the line = 36.5 + .48x, how do you interpret the value .48?rnrm.gif A. It's the amount of change in y when x increases by on

Xelga [282]

Answer:

A. It's the amount of change in y when x increases by one unit

Step-by-step explanation:

For this case we have the following linear model adjusted:

$\hat y = 36.5 +0.48 x$

Where y is the dependent variable, x the independent variable, 36.5 represent the intercept and 0.48 the slope.

We can analyze one by one the options to select the most appropiate.

A. It's the amount of change in y when x increases by one unit

True, for this case the slope is defined as:

$m =0.48 \frac{\Delta y}{\Delta x}$

And is defined as the amount of change in y when x increase 1 unit.

B. It's the value of y when x = 0

False the value of y when x=0 is y= 36.5+0.48(0) = 36.5

C. It's the value of x when y = 0

False, when y=0 we have this:

$0=36.5 +0.48 x$

$x= -\frac{36.5}{0.48}=-76.04$

D. It's the mean of the distribution for the response variable (y) around the explanatory variable (x)

False, the value 0.48 represent the slope obtained from an estimation of least squares and not represent the mean for the response variable y.

E. It's the amount of change in x when y increases by one unit.

False, is defined inverse as: the amount of change in y when x increase 1 unit.
