Answer:
I got x<equal to -11 or x>equal to4
Step-by-step explanation:
x^2+15x+44=0
(x+4)(x+11)=0(Factor left side of equation)
x+4=0 or x+11=0(Set factors equal to 0)
x=−4 or x=−11
Check intervals in between critical points. (Test values in the intervals to see if they work.)
x<−11(Works in original inequality)
−11<x<−4(Doesn't work in original inequality)
x>−4(Works in original inequality)
Answer:
x<−11 or x>−4

Step-by-step explanation:
I'm using the second question as an example.
To find the Unit Rate, you have to divide the amount of money by the amount of whatever the product is
5.99/8= 0.74875
Since the question says to round it to the nearest hundredth, that means the price per unit (unit rate, or the price for one battery here) would be about $0.75. Simple, right?
A production manager at a wall clock company wants to test their new wall clocks. The designer claims they have a mean life of 16 years with a standard deviation of 5 years. If the claim is true, in a sample of 32 wall clocks, what is the probability that the mean clock life would be greater than 15.6 years

In an election for school president, the loser received 70% of the winner's votes. If 969 votes were cast, how many did each receive?
Answer:
The ans would be 291 (however we can round this off to 290 as no can partially vote as 0.1)
Step-by-step explanation:
We can easily find the loser's vote by-
70% of 969= 678.9
now, all we need to do is find the winners vote
we know that the total no. of votes= 969 & we know the no. of votes loser got
so, subtracting the losers vote from 969 would give us the remaining no. of votes (the winner's votes)....so,
969-678.9=290.1
we can round this off to 290
When someone donated 14 gallons of paint to Rosendale Elementary School, the fifth grade decided to paint a mural. They split the gallons equally among the four classes.
b. how much paint will three classes use?
c. If 4 students share a 30-square footwall equally, how many square feet of the wall will be painted by each student?
d. what fraction of the wall will each student paint?
Answer:
Step-by-step explanation:
So, first we can do 14/4 which is 3.5
Each class uses 3.5 gallons
For (B), we can do 3.5 * 3 which equals 10.5 gallons
For (C), we can do 30÷4 which is 7.5 square feet
For (D) they each paint 1/4 of the wall

Given a normal distribution with a mean of 120 and a standard deviation of 12, what percentage of values is within the interval 96 to 144
Answer:
0.9545
Step-by-step explanation:
Given that :
Mean (m) = 120
Standard deviation (s) = 12
what percentage of values is within the interval 96 to 144
P(96 < x < 144)
P(x < 96)
obtain the standardized score (Z) :
Z = (x - m) / s
Z = (96 - 120) / 12 = - 2
p(Z < - 2) = 0.02275 ( Z probability calculator)
P(x < 144)
obtain the standardized score (Z) :
Z = (x - m) / s
Z = (144 - 120) / 12 = 2
p(Z < - 2) = 0.97725 ( Z probability calculator)
p(Z < - 2) - p(Z < 2) = 0.97725 - 0.02275 = 0.9545

A wise man once said, “400 reduced by 3 times my age is 163.” What is his age? ( I need the step by step equation to solve this)
Answer: the wise man is 79
Step-by-step explanation:
400 - 3x = 163
400–163 =3x
237 = 3x or 3x = 237 or x = 79…

TS is an angle bisector. If m∠RTS=x+10 and m∠UTS=2x+5, find m∠RTU.
answer choices below
30°30 degrees
15°15 degrees
80°80 degrees
5°
Answer:
m∠RTS= 15°, m∠UTS= 15°, m∠RTU= 30°
Step-by-step explanation:
Since TS bisects RTS and UTS, that means the two angles are equal to each other. So let's find x first.
x+10=2x+5, subtract x to both sides
10=x+5, subtract 5 to both sides
x=5
Since RTU is basically RTS plus UTS, let's add the two angles together
x+10+2x+5, combine like terms
3x+15
Then we can plug in 5 for x
3(5)+15
15+15
=30
So, RTU is 30 degrees
