As shift manager at a local fast food place, you are responsible for ensuring quality control. You do not want to weigh all the frozen hamburger patties that get delivered by your supplier to make sure they weigh four ounces on average, so you choose 100 patties at random. You calculate that the sample mean weight of patties is 2.6 ounces and the standard deviation of the weight of hamburger patties to be 0.4 ounces.

Required:
a. Test the hypothesis that the population mean weight of patties is equal to 4 ounces.
b. You are particularly concerned about the population weight being under 4 ounces, is there any reason for concern? Explain using the concept of a confidence interval.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

xbar = 2.6

Sample size, n = 100

s = 0.4

Mean, μ = 4

The test statistic :

(xbar - μ) ÷ s/sqrt(n)

(2.6 - 4) ÷ 0.4/sqrt(25)

1.4 ÷ 0.08

= −17.5

Critical tvalue for 95% confidence interval :

df = n - 1 = 25 - 1 = 24

Tcritical at 0.05/2; df

Tcritical = ±2.064

Since, Tstatistic value does not fall within the Tcritical value ±2.064, we reject the Null

Using the p value from Tstatistic calculator :

P value at t = - 17.5 at 0.05 < 0.000001

Since p value is < 0.05, we reject H0.

If x = 3x + 4 - 1 , then what does -x equal?

Answers

Answer:

-4/5 = x

Step-by-step explanation:

Answer:

3/2

Step-by-step explanation:

x = 3x + 4 - 1

we can subtract 1 from 4

x = 3x + 3

subtract 3x from both sides

-2x = 3

divide both sides by -2

x = -3/2

so -x would equal -(-3/2) = 3/2

What was the annual interest rate?

Answers

Answer:

1.2%

Step-by-step explanation:

Solving our equation

r = 10.2 / ( 425 × 2 ) = 0.012

r = 0.012

converting r decimal to a percentage

R = 0.012 * 100 = 1.2%/year

i kinda need your help.. pls help me...
I'm really not good at math pls... answer it or pls explain me how do I do this??? how can I multiply or divide this????? PLS HELP ME

Answers

When there is a negative to the power of x, it makes it a 1/x to that power. (X^-5 becomes 1/x^5)

For two x’s to a power in a fraction (x^6/x^7), you subtract the greatest x power by the least x power. So, it will become 1/x (7-6=1, the six up top disappears but you still need the x on the bottom as it did not disappear, which is where the 1 comes from)

Marianne has a scarf that is 5 inches longer than it is wide. if the area of her scarf is 84 square inches. what are the dimensions of her scarf?

Answers

Answer:

The dimensions of Marianne scarf = 12 × 7 inches

The length of the scarf =12inches

The width of the scarf = 7 inches

Step-by-step explanation:

Step(i):-

Let 'x' be the width of the scarf

Given that the length of the scarf = x+5

The area of the rectangle = length × width

Given that the area of the rectangle (scarf) = 84 square inches

Step(ii):-

length × width = 84

(x+5) × x = 84

x² + 5x - 84 =0

x² + 12 x - 7 x - 84 =0

x(x+12) -7( x+12) =0

(x-7)(x+12) =0

x -7 =0 and x+12=0

x =7 and x= -12

Step(iii):-

We have to choose x =7

The length of the scarf = x+5 = 7+5 =12inches

The width of the scarf = x = 7 inches

What is the angle of elevation from point A to point C?

Answers

Answer: b

Step-by-step explanation:

By the alternate interior angles theorem, the angle of elevation and the angle of depression have the same measure.

The measure of angle A is 32 degrees or the measure of the angle of elevation is 32 degrees option (b) 32 degrees is correct.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

It is given that:

The right-angle triangle is shown in the picture.

The right-angle triangle is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

As the two lines are parallel to each other and a transversal is intersect the parallel lines so the angle would be same as 32 degrees

The angle A = 32 degrees

Thus, the measure of the angle A is 32 degrees or the measure of the angle of elevation is 32 degrees option (b) 32 degrees is correct.
