A police officer recorded the speeds of 100 cars in a 50-mile-per-hour zone. The results are in the box plot shown. How many cars were going between 40 and 48 miles per hour?​ I know the answer but I need to know how to do it

Answers

Answer 1

Answer: 25 cars

Step-by-step explanation:

This is a box plot and it is a useful graph for showing the minimum, maximum, median and quartile values of a data distribution.

The box you see in the middle is the Interquartile range. In other words, the first line on the box is Q1 and the line at the end of the box is Q3.

The line in the middle of the box is the median or Q2.

The distance between Q1 and the median is 25%.

The number of cars between 40 and 48 miles per hour is therefore 25% of the total.

= 100 * 25%

= 25 cars

The price of a pair of shoes increases from $65 to $81. What is the percent increase to the
nearest percent?

Answers

Answer:

Percent increase = 25%

Step-by-step explanation:

Given that:

Old price of shoes = $65

New price of shoes = $81

Difference = 81 - 65

Difference = 16

Percent increase = [tex]\frac{Difference}{Old\ price}*100[/tex]

Percent increase = [tex]\frac{16}{65}*100[/tex]

Percent increase = 0.246 * 100

Percent increase = 24.6%

Rounding off to nearest whole number

Increase = 25%

Hence,

Percent increase = 25%

Find the percent change if the original is $300 and the new cost is $1,100?

Answers

The percentage change from $300 to $1,100 is 266.67% increase

How?

1,100 - 300 ÷ 300 = 2.6667

2.6667 x 100 = 266.67%

^this is how you find the percent in change

(You could have just asked me to show my work instead of reporting me- that was a bit uncalled for)

Answer: $266.667% change

Step-by-step explanation:

(V2 - V3) (1100 - 300) 800

_______ x100 = ________ x 100 = ____ x 100= $2.66667% = $266.667%

Which speed is the fastest?

A: 4 miles in 1/3
B: 1/3 mile in 4 hours
C: 1/2 mile in 3 hours
D: 2 miles in 1 hour

Answers

1/3 of an hour is 20 minutes so 20 divided by 4 is 5 minutes per 1 mile.

1/3 of a mile is 4 hours so a full mile would be 3 times 4 which is 12 so every 12 hours is 1 mile.

1/2 a mile takes 3 hours and 2 times 3 is 6 so every 6 hours is 1 mile.

A. 5 minutes per mile

B. 12 hours per mile

C. 6 hours per mile

The correct choice is A.

An estimate of the height, H metres, of a tall building can be found
using the formula

where the building is f floors high.
A building is 85 floors high.
The real height of the building is 260m.
Work out the percentage error when estimating the height of this building using
the formula given.

Answers

Given that,

An estimate of the height, H metres, of a tall building can be found  using the formula :

H = 3f + 15

where the building is f floors high.

f = 85

The real height of the building is 260 m.

To find,

The percentage error.

Solution,

We have,

H = 3f + 15

Put f = 85 in the above formula

H = 3(85) + 15

H = 270 m

Error,

[tex]E=\dfrac{270-260}{260}\times 100\\\\=3.84\%[/tex]

So, the required error is 3.84%.

A bouquet of flowers contains a total of 24 red and white roses. The number of red roses is 4 less than three times the number of white roses.



How many of each color rose are in the bouquet?
(with preferred work)

Answers

Answer:

White roses - 7

Red roses - 17

Step-by-step explanation:

Set up proportional equations

White roses = x

Red roses = 3x - 4

Set equal to 24

x + 3x - 4 = 24

4x - 4 = 24

4x = 28

x = 7

x is white roses, so there are 7

Plug x value into red rose equation

3(7)-4

21-4 = 17 red roses

Check

17+7 = 24

two angles of an isosceles triangle are x and x+10.find two possible value of x​

Answers

Recall two important facts:

- An isosceles triangle always has two identical angles

- The interior angles always add up to 180 degrees

Armed with this info, we can set up two different equations to solve for x, depending on which angle we treat as being one of the pair of identical angles.

If we assume that the identical angles are x, then:

180 = 2x + x + 10

170 = 3x

56[tex]\frac{2}{3}[/tex] = x

Alternately, we can assume that the identical angles are x+10.  In this case:

180 = 2(x + 10) + x

180 = 2x + 20 + x

160 = 3x

53[tex]\frac{1}{3}[/tex] = x
