A set of data is normally distributed with a mean of 455 and a standard deviation of 25. What percent of the data is in the interval 405–455?
a.
47.5%
c.
68.3%
b.
49.85%
d.
34.15%

Answers

Answer:

a. 47.5%

Step-by-step explanation:

1. Find the z-score for 405: 405-455/25 = -2

2. Find the z-score for 455: 455-455/25 = 0

3. Using technology or a chart, find the percentage that corresponds with the z-scores: -2 = 0.0228 or 2.28%, AND 0 = 0.5000 or 50%

4. Find the difference between the percentages by subtracting them: 50% - 2.28% = 47.72%

5. Most of the time, the answers aren't exact, so since 47.72% is closest to 47.5%, I would say that's the answer.

17. You sell large and small pictures at a fair. You sell a total of 16 pictures and made a total of
$350. If large pictures sell for $25 and small pictures sell for $20. How many of each did you
sell?

Answers

Make a system of equation
Let L be large pictures
Let S be small pictures
You know they add to 16 pictures
You know each cost

(L + S = 16) * 25
25L + 20S = 350
25L + 25S = 400
Subtract (elimination method)
-5S = -50, S = 10
L + 10 = 16, L = 6

Solution: 10 small pictures
6 large pictures

It is said that if you are with someone else, you do not have to outrun the wolf, you just
have to outrun the other person.
Suppose that a wolf can run 15 m/s, you can run 10 m/s and your friend can run 5 m/s.
You start 15 meters away from the wolf and your friend starts 20 meters, away from the
wolf.
Set up three equations and then answer using your perfered method
(table/graphing/theory): Who gets caught first and when (in seconds)?

Answers

Answer:

The three equations:

y = 15x, wolfy = 10x + 15, youy = 5x + 20, friend

Compare the equations with wolf and you and with wolf and your friend:

15x = 10x + 155x = 15x = 3 seconds

It will take 3 seconds before you are caught by the wolf

15x = 5x + 2010x = 20x = 2 seconds

It will take 2 seconds before your friend is caught by the wolf, he will be caught a second before you.

The diagram below shows Cameron's budgeted expenses for a trip he is planning. O $46.08 O 580 O $1,200 O $4,608 CLEAR ALL Cameron has budgeted $240 for meals during his full trip. What is the total budget for the trip?
A $46.08
B $80
C $1,200
D $4,608​

Answers

Answer:

C $1,200

Step-by-step explanation:

The computation of the total budget fro the trip is as follows:

Since it is given that the budgeted amount for meals is $240 i.e. equivalent to 20%

By this information we can easily compute other budgeted expenses

For Lodging

= $240 × 0.32 ÷ 0.20

= $384

For transportation

= $240 × 0.36 ÷ 0.20

=   $432

For Gifts

= $240 × 0.12 ÷ 0.20

= $144

Now the total budget for the trip is

= $384 + $240 + $432 + $144

= $1,200

Answer:

Step-by-step explanation:

The 155° angle in the piece that is left if the piece of cake with a 25° angle is eaten option (A) is correct.

What is a circle?

It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).

We have half of a circular cake is left after a party.

A piece of cake with a 25° angle is eaten.

We know the circle is a complete revolution of lines that joins from a fixed point to point at a certain distance; makes an angle 0f 360°

half of a circular cake with an angle = 360°/2  ⇒ 180°

25° angle piece eaten, then the remaining left portion:

= 180° - 25°

= 155°

Thus, the 155° angle in the piece that is left if the piece of cake with a 25° angle is eaten.

x = 18

Step-by-step explanation:

Answer:

x = 18

Step-by-step explanation:

Supplementary angles = 180°

110° + ( 3x + 16° ) = 180

110° + 3x + 16 ° = 180

126° + 3x = 180

3x = 180 - 126

3x = 54°

x = 54/3

Estimate the perimeter and the area of the shaded figure

Show how you got your answer

Answers

Answer:

Perimeter = 16 feet

Total Surface Area = 24 sq ft.

Step-by-step explanation:

Let's assume that each square is equal to 1 foot. Using this we can estimate the perimeter and area as the following. For perimeter, we simply add all the squares distances surrounding the shaded object.

Perimeter = 16 feet (4 feet for the top and bottom and 2 feet every diagonal)

For the area, we need to calculate the area of the square in the middle and then the area of the two triangles.

Square = L * W

Square = 4 * 4

Square = 16 sq ft

Triangle = 0.5 * Base * Height

Triangle = 0.5 * 4 * 2

Triangle = 4 sq ft

Both triangles = 4 sq ft * 2 = 8 sq ft.

Now we add both area totals:

Total Surface Area = 16 + 8

Total Surface Area = 24 sq ft.

To the nearest tenth of a centimeter, how tall is a cylinder with a radius of 8.4 cm and volume of 3119.5 cm3. Give the approximate answer rounded to 2 decimal places.

Thank you!

Answers

Answer:

r=8.4cm

v=3119.5cmcube

volume of a cylinder

=pie r square height

pie=22/7

22/7×8.4×8.4×h=3119.5cm cube

221.76cmsquareh=3119.5cm cube

___________________________

221.76cm square(both sides)

h=14.07cm

The height of the cylinder is h =  14.09 cm

Given data:

To find the height of the cylinder,  the formula for the volume of a cylinder: V = πr²h, where V is the volume, r is the radius, and h is the height.

Given that the radius is 8.4 cm and the volume is 3119.5 cm³, substitute these values into the formula and solve for h.

3119.5 cm³ = π(8.4 cm)²h

To isolate h, divide both sides of the equation by π(8.4 cm)²:

h = 3119.5 cm³ / (π(8.4 cm)²)

Now, calculate the approximate value of h as:

h ≈ 3119.5 / (π * 8.4²)

≈ 3119.5 / (3.14 * 70.56)

≈ 3119.5 / 221.1264

≈ 14.0989 cm

Hence , the height is 14.09 cm
