Help plz!!


Ryan worked at a local ice cream shop during the summer. The money he earned for the first six weeks is given below.

$40, $80, $38, $40, $32, $65

Ryan then earned $24 in the seventh week. How were the mean and the median affected?

The mean decreased, and the median remained the same.

The median decreased, and the mean remained the same.

The median and the mean both remained the same.

The mean and the median both decreased.

Complete question :

A survey found that women's heights are normally distributed with mean 63.6 in and standard deviation 3.7 in. The survey also found that men's heights are normally distributed with mean 69.3 in and standard deviation 3.7 in. Consider an executive jet that seats six with a doorway height of 55.7 in.

1-What percentage of adult men can fit through the door without bending?

2-) Does the door design with a height of 56.35in. appear to be adequate? Why didn't the engineers design a larger door? Choose answer below

A. The door design is inadequate, because every person needs to be able to get into the aircraft without bending. There is no reason why this should not be implemented.

B. The door design is adequate, because the majority of people will be able to fit without bending. Thus, a larger door is not needed.

C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.

D. The door design is adequate, because although many men will not be able to fit without bending, most women will be able to fit without bending. Thus, a larger door is not needed.

Answer:

A.) 0.135%

B.) C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.

C.)

Step-by-step explanation:

Percentage of adult men that can fit the door without bending :

Obtain the Zscore :

Mean height of men, m = 67.5

Standard deviation, s = 3.7

Zscore = (x - m) / s ; where x = 56.4

Zscore = (56.4 - 67.5) / 3.7

Zscore = - 11.1 / 3.7

Zscore = - 3

P(Z < - 3) = 0.0013499 (Z probability calculator)

P(Z < - 3) = 0.0013499 * 100% = 0.13499%

Answer:

[tex]\frac{9\sqrt{2} }{2}[/tex]

Step-by-step explanation:

This particular case is a sine operation.

sin(45°) = [tex]\frac{x}{9}[/tex]

9sin(45°) = x

Plug into a calculator and you get:

x = [tex]\frac{9\sqrt{2} }{2}[/tex]

Answer:

∡b = 53°

∡d = 127°

∡c = 127°

Step-by-step explanation:

in trapezoids, the two top angles are equal and the two bottom are equal

also, there are 360 degrees in any 4-sided polygon

53 + 53 + x + x = 360

2x + 106 = 360

2x = 254

x = 127

Answer:

127

Answer: 384 cm²

Step-by-step explanation:

Answer:

5 in.

Step-by-step explanation:

Given that

b1 = 12

b2 = 8

A = 50

Formula is (1/2)h(b1 + b2), on substituting

50 = 1/2 * h(12 + 8)

50 = 1/2 * h(20)

100 = 20h

h = 100/20

h = 5

The height is 5 in

Answer:

Answer:

a = 3, b = 2

[tex]y = 3\cdot 2^x[/tex]

Step-by-step explanation:

[tex]y = ab^x\\3 = ab^0\\12 = ab^2\\~\\3=ab^0=a\cdot 1 = a\\a = 3\\~\\12 = ab^2 = 3b^2\\4 = b^2\\b = 2 \vee b = -2[/tex]

but we know from the graph being defined and positive, that b cannot be -2

b = 2

The value of a is 3 and value of b is 2.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The graph is y=abˣ

The points with coordinates (0, 3) and (2, 12) lie on the graph.

We need to find the values of a and b.

The point (0, 3)

3=ab⁰

a=3

Now point (2, 12)

12=ab²

Now plug in a value as 3

12=3b²

Divide both sides by 3

12/3=b²

4=b²

b=2

Hence, the value of a is 3 and value of b is 2.

Answer:

answer is 60.48 m squared

Step-by-step explanation:

use the formula

a=1/2(b1+b2)h

a=1/2(15.8+6.6)h

a=1/2(22.4*5.4)

a=1/2(120.96)

a=120.96/2

a=60.48m

Step-by-step explanation:

you know that your line is perpendicular to the line with equation y equals 3x + 5 right whenever a line is perpendicular to another perpendicular not parallel to the line has a negative slope of the other line for example if you had a line with slope 2 x in the line perpendicular to that would have slope -1 / 2X so then you line in your question has slope -1 / 3 x by doing the Rococo of 3 and adding a negative sign to your equation sulfur looks like this y equals negative 1 / 3 x + B where is B is a constant 3 all you have to do is solve for b is a plug in the coordinate values 6 equals x minus -2 equals one in rearrange y equals -1 / 3 x + B negative two equals negative one over three 6 plus b negative two equals negative two plus be there for me easy roast F4U equation of the line is y equals -1 / 3 x

If my calculations are correct, I suppose the final answer will be 100 degrees.

If you see it, It's clearly mirrored.

The polygons name is an octagon and is not a regular polygon

Step-by-step explanation:

if you have 3/4 you divide the part, 3, by the whole, 4

3 ÷ 4 = 0.75

then multiply 0.75 by 100, 75, then add a percentage sign: 75%
