Hi! Can someone please help me with these two questions??!! Thank you so much!

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

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. :)

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

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.

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.

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

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.

Answer:

C-7.4

Step-by-step explanation:

just took the test EDG2020

The nth term of an arithmetic sequence is a +(n-1)d. The missing term of the arithmetic sequence is 7.4

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
