Really need help on my correction if anyone know please help!!

Answers:
Question 19: 177 bpm
Question 20: 95˚F

Explanations:
Question 19:
You had the formula set up properly like this:
$R = \frac{885 \sqrt{25} }{25} = \frac{885(5)}{25} = \frac{4425}{25}$
This is where you went wrong - I don't know exactly what you did, but your division of 4425 ÷ 25 is wrong. You should have ended up with 177 which is the correct answer.
Question 20:
You had the formula set up correctly again, and merely used the wrong sign when adding 32.
$F = \frac{9(35)}{5} + 32 = \frac{315}{5} + 32$
This is where you went wrong. You subtracted 32 from 63 when you should have added it. (See red circle on your subtraction.)
63 + 32 = 95˚F

Write x^2 − 8x + 13 = 0 in the form (x −

padilas [110]

If you would like to write the equation in the above form, you can calculate this using the following steps:

x^2 - 8x + 13 = 0
(x - 4)^2 = x^2 - 8x + 16
(x - 4)^2 - 3 = 0
(x - 4)^2 = 3

The correct result would be (x - 4)^2 = 3.

A bag hold 1 blue block and 3 yellow block. How many green Blocks should be added to the bag to makr the probability of randomly

Natasha_Volkova [10]

Hello,

Since there is 1 blue block and 3 yellow blocks that would equal to 4 blocks in total. So the question is asking how many green blocks would be needed to make it 1/2. So you would be needing 4 green blocks to make the probability of randomly selecting a green block from the bag to equal 1/2.

I hope this helped you!
