Answer:

The probability is approximately 0.3193

Step-by-step explanation:

The question parameters;

The mass between of the pilot for which the seat was designed, [tex]\overline x[/tex] = 140 lb and 191 lb

The mean weight of the new pilots, μ = 148 lb

The standard deviation of the weights new pilots, s = 30.3 lb

a. The z-score is given as follows;

[tex]z=\dfrac{\bar{x}-\mu }{{\sigma }}[/tex]

Therefore, we have;

[tex]z_{140}=\dfrac{140-148 }{{30.3 }} \approx 0.264\overline {0264}[/tex]

The p-value = 0.60257

[tex]z_{191}=\dfrac{191-148 }{{30.3 }} \approx 1.419\overline {1419}[/tex]

The p-value = 0.9222

The probability that the mean lie between the two values = 0.9222 - 0.60257 = 0.31963

Therefore, the probability that the weight is between the 140 lb and 191 lb ≈ 0.3196

360 hoped that helped

Answer:

240

Step-by-step explanation:

600 x .6 = 360

600 - 360 = 240

Answer:

Step-by-step explanation: Given that, The sum of two numbers is 60

ie, 1st no + 2nd no = 60

Let us assume that 1st no is ‘x’

then x + 2nd no = 60

=> 2nd no = 60 - x

According to question, 3 times the number is 12 more than the other

=> 3 * 1st no = 12 + 2nd no

=> 3 * x = 12 + (60 - x)

=> 3x = 12 + 60 - x

=> 3x + x = 72

=> 4x = 72

=> x = 72 / 4

=> x = 18

So 1st no = 18

And 2nd no = 60-x = 60–18 = 42

Varification:

=> 3 * 1st no = 12 + 2nd no

=> 3 * 18 = 12 + 42

=> 54 = 54

Varified

Ans: 18 and 42

So the inequality for this is 12.5x + 35 ≥ 105

and the amount of visits they need to get to their goal is 6 visits

Step-by-step explanation:

you subtract the points they already have (35) from both sides and you'll get..

12.5x ≥ 70

then you divide 12.5 from both sides and you'll get 5.6, or 6 visits

Answer:

20inches

Step-by-step explanation:

The length of the diagonal is gotten by using the pythagoras theorem as shown;

l^2 = h^2 + w^2

l is the length of diagonal

h is the height

w is the width

l^2 - 16^2 + 12^2

l^2  = 256 + 144

l^2 = 400

l = √400

l = 20in

Hence the  length of a diagonal of this picture frame in inches is 20inches

Thec at 95% is : 738.55  [tex]\leq N\leq[/tex] 759.45

We have the following information available from the question is:

A random sample of 36 drivers use on average 749 gallons of gasoline per year

The standard deviation of the population is 32 gallons.

We have to find the 95% confidence interval.

Now, According to the question:

x(bar) = 749

[tex]\sigma =32[/tex] gallon

n = 36

Confidence interval = 95%

Interval will be:

x(bar) - EBM [tex]\leq N\leq[/tex] x(bar) + EBM

where, EBM z [tex]\frac{\sigma}{\sqrt{n} }[/tex]

z = 1.'96 (For 95%)

x(bar ) - z [tex]\frac{\sigma}{\sqrt{n} }[/tex] [tex]\leq N\leq[/tex] x(bar) + z [tex]\frac{\sigma}{\sqrt{n} }[/tex]

[tex]749 - 1.96[/tex] [tex](\frac{32}{\sqrt{36} } )\leq N\leq 749+1.96(\frac{32}{\sqrt{36} } )[/tex]

749 - 10.453  [tex]\leq N\leq[/tex] 749 + 10.453

738.55  [tex]\leq N\leq[/tex] 759.45

Answer:

8x units

Step-by-step explanation:

A rectangle has an area of 56x²y units². If the height of the rectangle is 7xy. What is the length of the rectangle.

The Area of a Rectangle is calculated with the formula

Length × Width ( Height)

Area = 56x²y square units

Height = 7xy units

Length =Area of the rectangle/Height of the rectangle

= 56x²y square units/7xy units

= 8x units

Answer:

Part A:

Variable x = change in profit per month

8x = 7200

Part B:

$900 loss per month

Step-by-step explanation:

Part A:

Within 8 months, the company loses $7200. To show a change in profit per month we have to multiply change by 8 months to equal $7200. Since we do not know what the change per month is, we can represent it as a variable. In this case, I will use x.

Variable x = change in profit per month

8x = 7200

Part B:

Solve for the expression we created in part A

8x = 7200

Isolate the variable x by dividing both sides by 8

8x ÷ 8 = 7200 ÷ 8

x = 900

$900 loss per month

The correct expression will be ( 3 + 9) = ( 87 ÷ h ) + 9. The correct option is C.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is 3 / 5 = 17²/₅ ÷ h. The expression will be solved as below,

3 / 5 = 17²/₅ ÷ h

3/5 = 87 / 5 ÷ h

h = 87 / 3

h = 29

Check option C for the value of h = 29.

3 + 9 = ( 87 / h ) = 9

3 = 87 / h

h = 87 / 3 = 29

Hence. the correct option is C.

If Jack got the one month plan for two months, he would have to pay  $39.95 twice.

Cost of jack getting the one month plan for two months =  $39.95 x 2 = $79.90

Money saved = cost of the one month plan for two months - cost of the two months plan

Answer:

The answer is c, C=1.5w + 5

Step-by-step explanation:

Let's write a general equation first,

C = mw + b, where C represents the shipping cost, w is the weight, m and b are non-zero constants.

By using the set of data in the table, what we can do is to substitute the corresponding values into our general equation. [Use any 2 set of numbers]

11 = 4w + b --(1)

17 = 8w + b --(2)

Here we got 2 equations, 2 unknown, thus we can get

w = 3/2, b = 5

The answer is c, C=1.5w + 5

[Noted that if you already got the slope(the yellow words), you can simply substitute one set of numbers into C=1.5w + b to find the value of b]
