Answer:
c*(t)-((t-2)*(t+6)*(t-4))=0
Step-by-step explanation:
ct - ((t - 2) • (t + 6) • (t - 4)) = 0
ct - (t - 2) • (t + 6) • (t - 4) = 0
3.1 ct-t3+28t-48 is not a perfect cube
ct - t3 + 28t - 48 = 0
Solve ct-t3+28t-48 = 0

jacob works part time as a cashier at a drugstore. his gross pay for the year was $8000. Based on his income level, the federal tax rate he’ll need to pay is 10%. For his state taxes, Jacob will need to pay 5% and the FICA rate is 7.65%. What is jacobs net pay for the year?
A) 1,812
B) 6,988
C) 6,188
D) 7,200
The answer will be option B. The net pay for the jacob will be equal to $6,188.
What is gross pay?The amount paid by any company to the employees without any deductions like taxes or charges is called as the gross pay.
It is given that:-
Gross pay for the year was $8000
The federal tax rate he’ll need to pay is 10%.
Jacob will need to pay 5% and the FICA rate is 7.65%
So the total deductions from the gross pay will be calculated as:-
Deductions = 8000 X 10% +8000 x 5% +8000 x 7.5%
Deductions = 800+400+612=$1812
The net pay will be = 8000-1812 =$ 6188
Hence the net pay for the jacob will be equal to $6,188.

The botanist would like to estimate the average weight of mustard seeds grown in a certain type of soil; weight of the seeds is known to follow a normal distribution. The botanist collects a random sample of 10 mustard seeds and finds that the sample average and sample standard deviation are 528 mg and 49 mg respectively. Select from the following the correct 90% confidence interval for the true average weight of mustard seeds grown in Soil Type A using the above sample data.
a. (480.1, 539.9)
b. (525.2, 534.8)
c. (479.4, 540.6)
d. (473.6, 546.4)
e. The necessary assumptions have not been satisfied and the calculation cannot be performed.
f. (469.4, 550.6)
Answer:
The correct 90% confidence interval for the true average weight of mustard seeds grown in Soil Type A using the above sample data is (499.6, 556.4).
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
T interval
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 10 - 1 = 9
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.833
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 1.833\frac{49}{\sqrt{10}} = 28.4[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 528 - 28.4 = 499.6 mg
The upper end of the interval is the sample mean added to M. So it is 528 + 28.4 = 556.4 mg
The correct 90% confidence interval for the true average weight of mustard seeds grown in Soil Type A using the above sample data is (499.6, 556.4).

Answer:
2,995 or 35,940(?)
Step-by-step explanation:
I don't exactly remember how to do this so, I'll show you two different ways I solved this
Use the formula I=P*r*t
I=Interest
P=Principal
r=rate
t=time
To solve this you'll have to...
The principal is 29,950, the rate is 5% but it'll become a decimal which is 0.05, and the time is 2
Put it into the formula form 29,950*0.05*2= 2,995 in interest
Or...
You'll use the same formula, but this time multiply 0.05 by 12 since there are 12 months in one year which is 0.6, so...
29,950*0.6*2=35,940 in interest
I hope one works!

Answer:
minimum z: 3050
Step-by-step explanation:
The attached graph shows the feasible region as a white space. The dashed lines at its edges are part of the solution set. The vertex closest to the origin is the one that minimizes z: (x, y) = (59, 32).
The minimum value of z is ...

A closed rectangle box with a volume of 16 3 ft is made from two kinds of materials. The top and bottom are made of material costing 10 cents/ 2 ft and the sides from material costing 5 cents/ 2 ft . Find the dimensions of the box so that the cost of the materials is minimized. [Hint: The cost of each side is equal to the area of the side times its unit price]
Answer:
The dimensions of the box are;
2 feet, by 2 feet, by 4 feet
Step-by-step explanation:
The given parameters are;
The volume of the closed box = 16 ft³
The material with which the top is made = The material with which the bottom is made
The cost of the material with which the top and bottom is made = 10 cents/(ft.²)
The cost of the material with which the side is made = 5 cents/(ft.²)
Let 'x', 'y', and 'z' represent the length, width, and height of the material, we have;
x·y·z = 16...(1)
The total cost of the box = 2×10×x×y + 2×5×x×z + 2×5×y×z
∴ The total cost of the box = 20·x·y + 10·x·z + 10y·z...(2)
From equation (1)
z = 16/(x·y)
Therefore, we have;
20·x·y + 10·x·z + 10y·z. = 20·x·y + 10·x·16/(x·y) + 10y·16/(x·y)
20·x·y + 160/(y) + 160/(x)
Differentiating, we get;
f'(x) = 20·y - 160/x²
f'(y) = 20·x - 160/y²
20·y - 160/x² = 0
y = 8/x²
20·x - 160/y² = 0
x = 8/y²
∴ x = 8/(8/x²)² = x⁴/8
8 = x⁴/x = x³
x = ∛8 = 2
The length, x = 2 feet
y = 8/x² = 8/2² = 2
The width, y = 2 feet
z = 16/(x·y) = 16/(2 × 2) = 4
The height of the box, z = 4 feet
Therefore, the dimensions of the box are 2 feet, by 2 feet, by 4 feet.

I have attached an image showing the triangle with angle and distance depicted in the question.
Answer:
151 miles
Step-by-step explanation:
We have to first find the unknown angle in the triangle.
Sum of angles in a triangle is 180°.
Thus, if we call angle at Norfolk A, we have;
A = 180 - (83 + 31)
A = 66°
Using sine rule, we can find the distance which we will term as a.
Thus;
a/sin 83 = 139/sin 66
a = (139 × sin 83)/sin 66
a = 137.963915/0.913545
a ≈ 151 miles

400 UCF students were randomly selected and asked if they preferred washing their hands with soap and water or using hand sanitizer. 102 said they prefer to use hand sanitizer. 400 USF students were randomly selected and asked the same question. 112 said they prefer to use hand sanitizer. You want to examine the difference in the proportion of all UCF (1) and USF (2) students who prefer to use hand sanitizer.
1. Which test should be used to determine if a difference exists between the proportion of all UCF and USF students who prefer to use hand sanitizer?
a. z test for means t test for means.
b. z test for proportions paired.
c. z test for means.
d. paired t test for means.
2. Which alternative hypothesis should be used to determine if a difference exists between the proportion of all UCF and USF students who prefer to use hand sanitizer?
A. HA : mu1 - mu2 < 0.
B. HA : mu1 - mu2 is not equal to 0.
C. HA : mu1 - mu2 > 0.
D. HA : p1 - p2 < 0.
E. HA : p1 -p2 > 0.
Answer:
1. a. z test for means and t test for means.
2. C. HA : mu1 - mu2 > 0
Step-by-step explanation:
Hypothesis testing is used in a situation where there are more than 1 alternative available. The t test is conducted in the mean which determines the t value and then this value is compared with p value to identify the situation whether to accept or reject the null hypothesis. The alternative hypothesis in this situation is is represented by mu.

441-p²=(21)²-(17)²
maths algebra
Step-by-step explanation:
hope it will help you......
Answer:
p = 17
Step-by-step explanation:
→ Expand out (21)² - (17)²
21² = 441 and 17² = 289 therefore 441 - 289 = 152
→ Plug value back into equation
441 - p² = 152
→ Minus 441 from both sides
- p² = -289
→ Square root both sides
p = 17
