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
Solve the radical equation.
PLEASE HELPPPP
Please help!! Will mark brainilest ☺️
Answer:
B
Step-by-step explanation:
Because there's no change in x so it has to be a straight line going through the y-axis.
Also for A and C, they don't even touch y = 2 so you can easily cross those out.

Can someone explain thoroughly how I am meant to solve this?
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

Which size bottle of ketchup is the best deal with the lowest unit price?
Prices for Different Sizes of Bottles of Ketchup
Size Bottle
Price
10 oz.
$2.50
14 oz.
$2.80
16 oz.
$4.00
18 oz.
$5.40
Answer:
14oz for $2.80
Step-by-step explanation:
Well to determine the unit prices you must divide the price by whatever the weight is. As so:
10oz: 2.5/10=0.25
14oz: 2.8/14=0.20
16oz: 4/16=0.25
18oz: 5.4/18=0.30
So your answer is 14oz for $2.80
Answer: I’m pretty sure ur answer would be 14 oz. :)

The nth term of an arithmetic sequence is a +(n-1)d. The missing term of the arithmetic sequence is 7.4
How to calculate the nth term of an arithmetic sequence?The nth term of an arithmetic sequence is expressed according to the formula as shown:
Tn = a + (n -1)d
where:
a is the first term = 2
d is the common difference = 3.8 -2 = 1.8
Required
Fourth term (n = 4)
Substitute
T4 = 2 + (4 -1)(1.8)
T4 = 2+3(1.8)
T4 = 7.4
Hence the missing term of the arithmetic sequence is 7.4

A store clerk tells you that if you use a 10% off coupon the $30 jacket you want will only cost $20. What mistake has she made? What is the true cost of the jacket?
Answer: The true cost of the jacket is $27 dollars.
Step-by-step explanation: To find the cost of the jacket after the discount just do 30 X .1 to get 3. Then take 3 and subtract it from 30. The mistake the clerk made was he probably just saw 10% and did 30-10=20. The clerk might have brain damage because this is like 5th grade math.

Gas prices are expected to rise 5% each week for the next six weeks. Kevin spent $52.50 to fill his tank this week.
Which of the following represents the total amount Kevin can expect to spend to fill his tank over the next three
weeks, if he fills his tank once a week?
$52.50 + $55.13 + $57.76
$52.50 - $55.13 + $57.88
$55.13 + $57.76 - $60.39
$55.13 - $57.88 + $60.78
Answer:
D. $55.13 - $57.88 + $60.78
Step-by-step explanation:
52.50 x 1.05= 55.125 = 55.13
55.13 x 1.05= 57.88125 = 57.88
You can already eliminate a, b, and c because they don't match, so the answer is D.
The total amount is 55.13+57.88+60.78. Therefore, option D is the correct answer.
Given that, gas prices are expected to rise 5% each week for the next six weeks. Kevin spent $52.50 to fill his tank this week.
What is the percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100.
Now, in the first week 105% of 52.50
52.50 x 1.05= 55.125 = 55.13
In the second week 105% of 55.13
55.13 x 1.05= 57.88125 = 57.88
In the third week 105% of 57.88
57.88x 1.05= 60.775=60.78
So the total amount=55.13+57.88+60.78
Therefore, option D is the correct answer.
