Noise levels at 4volcanoes were measured in decibels yielding the following data:152,157,157,158Construct the 90%confidence interval for the mean noise level at such locations. Assume the population is approximately normal.Step 3 of 4:Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.

Answers

Answer:

t critical = 2.353

CI = (152.82 , 159.18)

Step-by-step explanation:

We are required to find the t critical value and also confidence interval

The sample mean is = 152+157+157+158/4

= 156

The standard deviation is 2.7

At a confidence level of 90%, we have α = 1 - 0.90 = 0.1

α/2 = 0.1/2 = 0.05.

Degree of freedom = 4-1 = 3

When we look this up in the t critical value table,

t critical = 2.353

Next we have to find the confidence interval

CI = (156 - 2.3530 x 2.7/√4 , 156 + 2.353 x 2.7/√4)

= 156-3.17655, 156+3.17655

CI = (152.82 , 159.18)

Upper bound = 159.18

Lower bound = 152.82

The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000 miles and a standard deviation of 1600 miles. What warranty should the company use if they want 94% of the tires to outlast the warranty?

Answers

Answer:

The warranty the company should use is of 57,520 mile.

Step-by-step explanation:

Let X denote the tread life of a particular brand of tire.

It is provided that, [tex]X\sim N(60,000, 1600^{2})[/tex].

Also provided that the company wants 94% of the tires to outlast the warranty.

Let x denote the warranty .

That is, P (X > x) = 0.94.

⇒ P (X < x) = 0.06

⇒ P (Z < z) = 0.06

The corresponding value of z is -1.55.

*Use a z-table.

Compute the value of x as follows:

[tex]z=\frac{X-\mu}{\sigma}\\\\-1.55=\frac{x-60000}{1600}\\\\x=60000-(1.55\times 1600)\\\\x=57520[/tex]

Thus, the warranty the company should use is of 57,520 mile.

The length of a rectangle is four times its width. Twice the perimeter of that rectangle is 160 cm. Find
the length and width of that rectangle. pls answer fast

Answers

Answer:

Step-by-step explanation:

Given twice the perimeter of rectangle =160

Let width of the rectangle=X

So length of the rectangle =4x

2(perimeter of rectangle)=160

2[2(length+width)]=160

4(4x+x)=160

5x=160/4

5x=40

X=40/8

X=5cm

So length of the rectangle =4x

=20cm

Width of the rectangle =X

=5cm.

Length = 4*5 = 20 cm

Width. = 4 cm.

given g (x)= f (x)+k. Identify a value of k that transforms f into g. Round your answer to the nearest integer.

Answers

K= 5

Step-by-step explanation:

You must count the distance between so if you look at where it lines up perfect -3,0 up to 2 the distance is 5

Answer:

k = - 5

Step-by-step explanation:

The slopes are same and y-intercepts are:

2 for f and -3 for g

Since we have:

g(x) = f(x) + k

We can find the value of k:

-3 = 2 + kk = -3 - 2k = -5

Answer is k = - 5

(04.02 LC) The graph below shows the numbers of cups of apple juice that are mixed with different numbers of cups of lemon-lime soda to make servings of apple soda: What is the ratio of the number of cups of apple juice to the number of cups of lemon-lime soda? (5 points)

Answers

Answer:

Ratio of the number of cups of apple juice to the number of cups of lemon lime soda is 6 : 1

Step-by-step explanation:

From the graph attached,

Number of cups of apple juice (A) is proportional to the number of cups of lemon lime soda (L).

A ∝ L

A = kL

Here 'k' is the proportionality constant.

k = [tex]\frac{A}{L}[/tex]

= [tex]\frac{6}{1}[/tex]

Therefore, ratio of the number of cups of apple juice to the number of cups of lemon lime soda is 6 : 1.

A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 19 feet more than the length of the shortest side. Find
the dimensions if the perimeter is 163 feet.
What is the length of the shortest side?
The length of the shortest side is

Answers

This is simple as the perimeter is given. All you have to do is make an expression and then equate it to the perimeter.

Side lengths:

Shortest Side: [tex]x[/tex]

1st side: [tex]2x[/tex] (Given that it's twice the length of the shortest of twice of [tex]x[/tex])

3rd side: [tex]x + 19[/tex] (Given that it's 19 more than the length of the shortest side or [tex]x[/tex])

Since the perimeter is just the addition of all the sides of the shape, the perimeter is going to be the addition of all the expression we made.

So the final expression is going to be: [tex]x + 2x + x + 19[/tex]

This is nothing but the perimeter so we can therefore equate it to [tex]163[/tex]

[tex]x + 2x + x + 19 = 163[/tex]

Now we solve the equation. Here it goes!:

[tex]4x + 19 = 163\\4x = 163 - 19\\4x = 144\\x = 144/4 = 36[/tex]

Therefore, [tex]x = 36[/tex]

So now we plug them into the previous expressions we made for the sides and you get:

Shortest side: [tex]36[/tex]

1st side: [tex]72[/tex]

3rd side: [tex]55[/tex]

And also, the length of the shortest side is [tex]36[/tex] as mentioned previously :D
