Given a normal distribution with u = 75 and o = 40, if you select a sample of n = 16, a) what is the probability that the sample mean is above 95? (4 d.p.) b) What is the value, of which there is 97.5% chance that a sample mean is less than that value? (1 d.p.)
Answers
Answer:
a) 0.0228
b) 94.6
Step-by-step explanation:
The formula for calculating a z-score when you are given a random.number of samples is z = (x-μ)/σ/√n
where x is the raw score
μ is the population mean
σ is the population standard deviation
n = random number of samples
Given a normal distribution with u = 75 and o = 40, if you select a sample of n = 16,
a) what is the probability that the sample mean is above 95? (4 d.p.) b)
= x = 95
Hence:
z = 95 - 75/40/√16
= 20/40/4
= 20/10
= 2
Probability value from Z-Table:
P(x<95) = 0.97725
P(x>95) = 1 - P(x<95) = 0.02275
The probability that the sample mean is above 95 to 4 decimal places = 0.0228
b) What is the value, of which there is 97.5% chance that a sample mean is less than that value?
97.5% chance = z score for the confidence interval = 1.96
Hence:
z = (x-μ)/σ/√n
1.96 = x - 75/40/√16
1.96 = x - 75/ 40/4
1.96 = x - 75/10
Cross Multiply
1.96 × 10 = x - 75
19.6 = x - 75
x = 19.6 + 75
x = 94.6
The value, of which there is 97.5% chance that a sample mean is less than that value is 94.6

Answers
6x2 + -18x + -18 = 6
Reorder the terms:
-18 + -18x + 6x2 = 6
Solving
-18 + -18x + 6x2 = 6
Solving for variable 'x'.
Reorder the terms:
-18 + -6 + -18x + 6x2 = 6 + -6
Combine like terms: -18 + -6 = -24
-24 + -18x + 6x2 = 6 + -6
Combine like terms: 6 + -6 = 0
-24 + -18x + 6x2 = 0
Factor out the Greatest Common Factor (GCF), '6'.

Step-by-step explanation:
3.75h is $3.75 multiplied by h, the amount of hamburgers they buy. same goes for 0.5d it’s 50¢ multiplied by d, the amount of drinks they buy. then both those variables added has to equal $25.50 because that’s how much they spent total.

What is the ratio of 11 inches to 3 feet? (Change the feet to inches.) Group of answer choices
11:36
36:11
3:11
11:3
Answers
Answer:
The first option (11:36)
Step-by-step explanation:
When you convert the 3 feet to inches, you multiply by 12. There is 12 inches in each foot, so multiply 3 by 12 will result in 36.
We are comparing the 11 inches to the 3 feet (36 inches), so it would look like this:
11 : 36
(Can also be shown as 11 - 36)
1 Foot = 12 inches
3 feet x 12 = 36 inches.
Ratio = 11:36

What is slope ?Slope is the rate of change.It can also be thought of as rise over run.
According to the given question slope(m) is 1/4 and point is (-8,6).
We know equation of a line in slope intercept form is y = mx + b, where b is the y intercept.
∴ 6 = (-8)1/4 + b.

Write the equation of the line passing through the points (6,16) and (9,25).
First find the slope!
Answers
Answer:
y = 3x - 2
Step-by-step explanation:
Find the slope using rise over run (y2 - y1) / (x2 - x1), where (x1, y1 ) and (x2, y2) are points on the line.
Plug in the 2 points:
(y2 - y1) / (x2 - x1)
(25 - 16) / (9 - 6)
9 / 3
= 3
So, the slope is 3. Plug this and a point into y = mx + b to find b:
y = mx + b
16 = 3(6) + b
16 = 18 + b
-2 = b
Then, plug in b and the slope into the equation:
y = mx + b
y = 3x - 2 is the equation of the line

Step-by-step explanation:
1. For x number of cupcakes, at 4 minutes each, the time required for their decoration is 4x.
For y number of cakes, at 32 minutes each, the time required for their decoration is 32y.
The total decorating time must be less than or equal to 224 minutes:
