PLEASE HELP ME. I NEED TO ANSWER THIS ASAP. I WILL LOVE YOU FOREVER OMG. Okay so the question is - Keith is racing this little sister Pattie and has given her a 15 foot head start. She runs 5 ft/sec and he is chasing at 8ft/sec. For how long can Pattie stay ahead of Keith?

Answers

Keith runs (8 - 5) = 3 ft per sec faster than Pattie, so every second he gets 3 ft closer to her. If they do that for (15/3) = 5 seconds, he'll catch up to her.

How do u solve 4(y-3)+9-3y

Answers

if you need to find the y, and the
4(y-3)+9-3y=0, then
we use PEMDAS, parenthesis first
4y-12+9-3y=0
4y-3y-12+9=0
y-3=0 add 3 on both sides
y=3

$4(y-3)+9-3y=0 \n 4y-12+9-3y=0 \n y-3=0 \n y=3$

If a rectangle measures 20 meters by 48 meters, what is the length, in meters, of the rectangle?

The junior class has 50 students. Twenty-five students take only French, 15 take only Latin, and 10 take both. If a student is chosen at random from the class, what is the probability that the student chosen takes either French only or Latin only? 1/2 4/5 1

Answers

The answer is going to be 4/5

The answer is 4/5 because the combined probability (French only is .5, and Latin only is .3) for French only and Latin only is .8, which is equal to 4/5.

The scatterplot shows the time it takes for a new hot plate to boil various amounts of water, and one lab group’s attempt at a line of best fit. What feedback should another lab group give during a peer review of the work? The line of best fit is reasonable because it does not go through any points. The line of best fit is reasonable because it goes through the largest cluster of points. The line of best fit is not reasonable because it does not go through any points. The line of best fit is not reasonable because it has more points below it than above it.

Answers

The feedback the other lab group should give is (d) the line of best fit is not reasonable because it has more points below it than above it.

From the scattered plot (see attachment), we can see that the scattered plot has a total of 7 dots,

5 of which are below the line of best fit,
1 is on the line of best fit, and the other one is above it.

There are more points below the scattered plot, than above it.

This means that the scattered plot is not reasonable because of (d)
