Answer:

Option 3

Step-by-step explanation:

Options numbered 1 to 4, top to bottom

Plot the scores in increasing order

20, 24, 25, 27, 29, 31, 34

The first and forth options can be eliminated because the whiskers do not cover the upper end of the range correctly. First ignores 34 and last includes 35, which is not in our score list.

The second option incorrectly places the median score at 25

The third option correctly places the median score at 27, the lower quartile at 24, and the upper quartile at 31

A speedometer has a percent error of 10%. The actual speed of the car is 40 mph. Select from the drop-down menus to correctly co

rodikova [14]

Answer

The speedometer is likely to show the speed is either 36.0 mph or 44.0 mph.

To prove

Formula

$Percentage\ error = \frac{error\times 100}{Exact\ value}$

Where error = |Approx value - Exact value |

First case

As given

A speedometer has a percent error of 10%. The actual speed of the car is 40 mph.

Here

Percentage error = 10%

Exact value = 40 mph

error = - (Approx value - Exact value )

= - (Approx value - 40 )

= - Approx value + 40

Put in the formula

$10 = \frac{(-Approx\ value + 40)\times 100}{40}$

$400 = {(-Approx\ value + 40)\times 100}$

$\frac{400}{100} =-Approx\ value + 40$

$\4 =-Approx\ value + 40$

Thus

Approx value = 40 - 4

Approx value = 36 mph

Therefore Option (b) is correct .

Second Case

error = (Approx value - Exact value )

= (Approx value - 40 )

= Approx value - 40

Put in the formula

$10 = \frac{(Approx\ value - 40)\times 100}{40}$

$400 = {(Approx\ value - 40)\times 100}$

$\frac{400}{100} = Approx\ value - 40$

$\4 = Approx\ value - 40$

Thus

Approx value = 40 + 4

Approx value = 44 mph

Therefore Option (c) is correct .

Tim is building a model of a castle with small wooden cubes. So far, Tim has constructed part of a security wall of the castle,

ioda

Answer:

The length has 9 cube so the length is 9/8 or 1 1/8 ft.

the width has 4 cubes, so the width is 4/8 or 1/2 ft.

The height has 11 cubes, so the height is 11/8 or 1 3/8 ft.

So, the volume of the portion of the security wall that Tim has constructed so far is 99/128 cu ft.
