Graph the line with slope <br> 2<br> 5<br><br> and <br> y<br><br> -intercept <br> −<br> 7<br><br> .
tia_tia [17]

Answer:

See attachment

Step-by-step explanation:

We want to graph the line with slope

m =  \frac{2}{5}

and y-intercept ,

b =  - 7

The equation of this line is

y =  \frac{2}{5}x - 7

Starting at -7 on the y-axis, we run 5 units and rise 2 units right.

Then draw a line through the y intercept and the new point

The graph is shown in the attachment.

A club is making posters to raise money. The printer charges a base fee of $270 and $2 per poster for supplies. A person sells e
sesenic [268]

<u>Answer:</u>

He must sell 190 posters make a profit of $300.

<u>Explanation: </u>

Given:

Base fee= $270  

Fee for supplies= $2

Cost of poster=$5

To find:

The number of posters to be sold to get a profit of $300=?

Solution:

Let the number of posters sold be n.

Now, we know that,

profit = selling price – cost price

$ 300 = $ 5 for each poster – ( $ 270 base fee + $ 2 for each poster)

300 = 5 x n – (270 + 2 x n)  

300 = 5n – 270 – 2n  

5n – 2n = 300 + 270  

3n = 570  

n=\frac{570}{3}

n = 190

The experimental probability is the probability based on previous outcomes, that is, the number of desired outcomes divided by the number of total outcomes.

While bowling with friends, Brandy rolls a strike in 57 out of 72 frames. What is the experimental probability that brandy will roll a strike the first frame of the next game?  

Desired outcomes:

57 strikes

Total outcomes:

72 frames

Probability:

p = 57/72 = 0.7917

79.17% probability that brandy will roll a strike the first frame of the next game

Building a model of an object "to scale" means that the height of the object is ____________ to the height of the model.
Zina [86]
The height of the object is EQUAL to the height of the model. We can see this in advertising when for example cereal is being advertised and on the box is says "actual size" because the cereal is drawn to scale.
