Need help with part c
Artyom0805 [142]
First understand that this is a linear graph. Find 2 points on the graph. We can use (0,1) and (3,-3).

Look at how much the x increases, in this case the x value increases by 0+3, so 3.

Then see how much the y value increases (make sure to evaluate them in the same order) 1 + (-3) = -2.

So you know that the y value decreases by 2 units for every 3 unit increase in x. Therefore the slope is y=(-2/3)x

Then figure out what you add to the end. The y intercept is (0,1), so add 1 to the end of y=(-2/3)x to move it up.

Your resulting eq is y=(-2/3)x+1

There are 1500 students in a school. 65% are girls. How many girls are there in the school?
bonufazy [111]

Answer:

975 girls

Step-by-step explanation:

To find 65% of 1500, multiply 1500 by .65 (to convert percentages to decimals, just move a decimal point over two spaces).

1500*.65=975

You can check that this answer is right with logic. Most of the students will be girls (more than 50%) and 975 makes up most of 1500.

Someone else asked this same question a while ago, and you can find their explanation here brainly.com/question/969975
