mrs. grady surveyed 30 students, 11 of which said they liked basketball, 16 of which said they liked hockey, and 3 of which said

Neko [114]

Out of 30 students, if you add up 11, 16, and 3, you get 30. Which means there is no remainder and there are no students that did not like either sport.

This is for Algebra 2 and I need help ASAP! 22pts if you show work and explanation

elixir [45]

Answer:

Part 41) The solutions are 3 and 1

Part 42) The solution is 2 only

Step-by-step explanation:

Part 41) we have

$\left|5x-9\right|=x+3$

step 1

Find the first solution (case positive)

$+(5x-9)=x+3$

$5x-x=3+9$

$4x=12$

$x=3$

step 2

Find the second solution (case negative)

$-(5x-9)=x+3$

$-5x+9=x+3$

$5x+x=9-3$

$6x=6$

$x=1$

therefore

The negative case was resolved incorrectly

The solutions are 3 and 1

Part 42) we have

$\left|n-7\right|=3n-1$

step 1

Find the first solution (case positive)

$+(n-7)=3n-1$

$3n-n=-7+1$

$2n=-6$

$n=-3$

<em>Verify</em>

For n=-3

substitute

$\left|-3-7\right|=3(-3)-1$

$\left|-10\right|=-9-1$

$10=-10$ ------> is not true

therefore

$n=-3$ -------> is not a solution

step 2

Find the second solution (case negative)

$-(n-7)=3n-1$

$-n+7=3n-1$

$3n+n=7+1$

$4n=8$

$n=2$

therefore

The solution is 2

A probability Qs, please help! thx!

sweet [91]

Answer:

10/13

Step-by-step explanation:

There are 52 cards in a standard deck. There are 4 queens (queen of spades, clubs, hearts, diamonds) and 36 (2 - 10 of four suites) number cards. Therefore the probability of drawing a queen or a number card is (4 + 36)/52 = 40/52 = 10/13.

Convert 3/8 into percent show the work

Kipish [7]

To get the decimal think of 3/8 as a division question -3 divided by 8

3/8=0.375

now times the decimal by 100

0.375 * 100=37.5

so the answer is going to be 37.5%
