Which company charges less per hour?
A. Company A
B. Company B
EXPLAIN
Answers
Explanation: This is because the fee plus the amount charged per hour equals 75 for Company B but If we do this with company A it’s 90 dollars so Company B is cheaper.
Example- For 3 hours
Company A: 40x3=120 adding on the fee of $170
Company B: 50x3=150 adding on the fee of $175

Complete Question
A baseball team had $1,000 to spend on supplies. The team spent $185 on a new bat. New baseballs cost $4 each.
The inequality 185 + 4b ≤ 1,000 can be used to determine the number of new baseballs (b) that the team can
purchase. Which statement about the number of new baseballs that can be purchased is true?
A. The team can purchase 204 new baseballs.
B. The minimum number of new baseballs that can be purchased is 185.
C. The maximum number of new baseballs that can be purchased is 185.
D. The team can purchase 185 new baseballs, but this number is neither the
maximum nor the minimum.
Answer:
D. The team can purchase 185 new baseballs, but this number is neither the maximum nor the minimum.
Step-by-step explanation:
The first step would be to solve the given equation:
185 + 4b ≤ 1000
4b ≤ 1000 - 185
4b ≤ 815
Divide both sides by 4
b ≤ 203.75
The maximum amount of baseballs the team can buy is 203. This means that they can buy 203 or less than that amount.
Of all the options give, option D is the correct option because the team can purchase 185 new baseballs, but this number is neither the maximum nor the minimum.
The maximum number of ball they can buy is 203 balls and the minimum is zero.

Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
Population standard deviation (σ) = 1.36
Sample size (n) = 5
A.)Standard deviation of sampling mean (σx) = (σ/√n)
(1.36/√5)
1.36 / 2.236
= 0.608
B.) With z = 3, the control limits for the mean
chart :
Control limit = m ± zσx
Using calculator ; mean (m) of the data = 10.40
Lower control limit : 10.4 - 3(0.608) = 8.576
Upper Control limit : 10.4 + 3(0.608) = 12.224
The control limit for the range :
Average value of range(R) in the sample = 3.6
Lower Control limit : R*D3
Upper control limit: R*D4
From the range chart table :
D3 = 0 ; D4 = 2.114
Lower Control limit : R*D3 = 3.6(0) = 0
Upper control limit: R*D4 = 3.6(2.114) = 7.61

According to an article, 75% of high school seniors have a driver's license. Suppose we take a random sample of 300 high school seniors and find the proportion who have a driver's license. Find the probability that more than 77% of the sample have a driver's license. Begin by verifying that the conditions for the Central Limit Theorem for Sample Proportions have been met
Answers
Using the normal distribution and the central limit theorem, it is found that there is a 0.2119 = 21.19% probability that more than 77% of the sample have a driver's license.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].In this problem, we have that:
75% of high school seniors have a driver's license, hence p = 0.75.A sample of 300 is taken, hence n = 300.The conditions are verified because:
np = 300 x 0.75 = 225 > 10.
n(1-p) = 300 x 0.25 = 75 > 10.
The mean and the standard error are given by:
[tex]\mu = p = 0.75[/tex]
[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.75(0.25)}{300}} = 0.025[/tex]
The probability that more than 77% of the sample have a driver's license is one subtracted by the p-value of Z when X = 0.77, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{0.77 - 0.75}{0.025}[/tex]
Z = 0.8
Z = 0.8 has a p-value of 0.7881.
1 - 0.7881 = 0.2119.
0.2119 = 21.19% probability that more than 77% of the sample have a driver's license.

We have,
Let's assume that the fishing boat traveled for x hours before the cruise ship caught up.
In that time, the fishing boat covered a distance of 10x km.
During the same 10 hours, the cruise ship traveled 14 x 10 = 140 km.
Since both the fishing boat and the cruise ship covered the same distance, we can write:
10x = 140
Solving for x, we get:
x = 14

The length of a rectangle is five times its width.
If the area of the rectangle is 405cm^2, find perimeter
Answers
Answer:
108
Step-by-step explanation:
Let's say the width is x
Of the length is 5 times the width, then the length is 5x
Area = length * width
405 = x * 5x
405 = 5x^2
405/5 = 5x^2/5
81 = x^2
Take the square root of both sides
2/[81 = 2/[x^2
9 = x = width
9 × 5 = 45 = length
Perimeter = 2 × length + 2 × width
2 × 45 + 2 × 9
90 + 18 = 108
