A student is assessing the correlation between the number of workers in a factory and the number of units produced daily?
Part A: Is there any correlation between the number of workers in a factory and the number of units produced daily? Justify your answer. (4 points)
Part B: Write a function that best fits the data. (3 points)
Part C: What does the slope and y-intercept of the plot indicate? (3 points)
Answers
Answer:
a) yes, because they both increase by the same increments each time. Tis can be represented by the equation y=5x+2
b) y=5x+2
c) The y-intercept represents the amount of units there were initially and the slope represents the amount of units for every worker.

Asha owns a car-wash and is trying to decide whether or not to purchase a vending machine so customers
can buy coffee while they wait. She'll get the machine if she's convinced that more than 30% of her
customers would buy coffee. She plans on taking a random sample of n customers and asking them
whether or not they would buy coffee from the machine, and she'll then do a significance test using
a = 0.05 to see if the sample proportion who say "yes" is significantly greater than 30%.
Suppose that in reality, it is actually 33% of her customers that would buy coffee.
Which of the changes below would result in the highest power for her test?
Answers
Answer: D
Step-by-step explanation:
She uses a sample size of n=200, and 50% of all customers would actually buy coffee.
The change that would result in the highest power for her test is D. increase the significance level to α = 0.01 and use a sample size of n = 300.
What is significance level?The significance level simply means the probability of rejecting the null hypothesis when it is true.
It should be noted that the power of the test depends on 4 factors which are the sample size, standard deviation, effect size, and significance level.
In the given scenario, the larger sample size will increase the power of the test and a higher significance level will result in a higher power.
Therefore, the test is done with the largest sample size and highest significance level of 0.10

A private ship carries two types of cargo: large crates and extra-large crates. Each type of crate weighs a specific amount.
On Saturday the ship carried 400 large crates and 275 extra-large crates weighing 18,800 tons.
On Sunday, the ship carried 190 large crates and 335 extra large crates, weighing 16,100 tons.
How much does an extra-large crate weigh in tons?
F 25 tons
G 32 tons
H 30 tons
J 24 tons
Answers
Answer:
G. 32
Step-by-step explanation:
32 x 335 = 10720
16,100 - 10720 = 5380/190 = 28.3157894737
275 x 32 = 8800
18,800 - 8800 = 10,000/400 = 25 (This is the closer).
30 x 335 = 10,050
16,100 - 10,050 = 6050/190 = 31.8421052632
30 x 275 = 8250
18,800 - 8250 = 10550/400 = 26.375 (Same reason why it does't work)
25 x 335 = 8375
16,100 - 8375 = 7725/190 = 40.6578947368
25 x 275 = 6875
18,800 - 6875 = 11925/400 = 29.8125
24 x 335 = 8040
16,100 - 8040 = 8060/190 = 42.4210526316
24 x 275 = 6600
18,800 - 6600 = 12200/400 = 30.5

The operation that results in the simplified expression x⁵ + x⁴ - 5x³ - 3x² + x - 8 is; P + Q
How to Simplify Polynomials?
We are given the Polynomials as;
P(x) = x⁴ + 3x³ + 2x² - x + 2
Q(x) = (x³ + 2x² + 3)(x² - 2)
We want to find the combination of P and Q that would yield;
x⁵ + x⁴ - 5x³ - 3x² + x - 8
Let us expand Q(x) to get;
Q(x) = x⁵ + 2x⁴ + 3x² - 2x³ - 4x² - 6
Q(x) = x⁵ + 2x⁴ - 2x³ - x² - 6
Now, the combined polynomial shows us that coefficient of x⁴ is 1 and coefficient of x³ is - 5.
By inspection, we can say that the combination that would produce the required result is;
Q(x) - P(x) = x⁵ + 2x⁴ - 2x³ - x² - 6 - x⁴ - 3x³ - 2x² + x - 2
Q(x) - P(x) = x⁵ + x⁴ - 5x³ - 3x² + x - 8

Step-by-step explanation:
The radius of semicircle window, r = 40 cm
The area of semicircle is given by :

Substitute all the values in the above formula.
[tex]A=\dfrac{\pi \times 40^2}{2}\\\\A=2513.27\ cm^2[/tex]
