The original price was $75.

$75 - 20% = $60.

$60 + 10% = $ 66.

75 - 66 = 9.

9 / 75 × 100 = 12%.

The correct answer is C

Answer: 12%

It is important to note that the coupon is applied first THEN the fee is applied.

First, we find the percent of the price that will be paid after the coupon is applied when converted to a decimal.
100%-20%= 80%= 0.8

Now, we multiple this decimal by the original price.
75(0.8)= 60

Then, we find the percent of the price that will be paid after the fee is added when converted to a decimal.
100%+10%= 110%= 1.1

Once we found the decimal we multiply it by the price after the coupon is applied.
60(1.1)=66

66 is 88% of 75, the original price or 100%.

Subtract new price from original value.
100%-88%= 12%

If you have any questions feel free to ask. :)

Which scale factors produce an expansion under a dilation of the original image?

alina1380 [7]

Answer: The correct options are (A) 8 and (D) 7.

Step-by-step explanation: We are given to select the correct scale factors that produces an expansion under a dilation of the original image.

The SCALE FACTOR of a dilation is defined as follows:

$\textup{Scale factor}=\dfrac{\textup{length of a side of the dilated image}}{\textup{length of the corresponding side of the original image}}.$

The dilation will be an expansion is the scale factor is greater than 1 (> 1),

and it will be a reduction if the scale factor is less than 1 (< 1).

Option (A) is

Scale factor = 8.

Since 8 > 1, so the scale factor of the dilation is greater than 1. This implies that the dilation is an expansion.

Option (B) is

Scale factor = 0.7.

Since 0.7 < 1, so the scale factor of the dilation is less than 1. This implies that the dilation is a reduction.

Option (C) is

Scale factor = 0.8.

Since 0.8 < 1, so the scale factor of the dilation is less than 1. This implies that the dilation is a reduction.

Option (D) is

Scale factor = 7.

Since 8 > 1, so the scale factor of the dilation is greater than 1. This implies that the dilation is an expansion.

Thus, the correct options are (A) 8 and (D) 7.

In a survey conducted by the marketing agency 11mark, 241 of 1000 adults 19 years of age or older confessed to bringing and usin

Ann [662]

Answer: kindly check explanation

Step-by-step explanation:

A) The sample is a fraction of the total population used in the study.

The sample is 1000 19 years of age or older U.S adult.

The population : all U.S adults aged 19 or older.

B.) Confession about bringing cell phone to the bathroom and it is a qualitative variable

C.) point estimate (p) :

Total number of sample = 1000

Number who confessed to bring cellphone = 241

p = 241/ 1000

= 241/1000 = 0.241

D.) The point estimate was deduced from the sample information and not the population. Random selection because selection is unbiased.

E.) 95% confidence interval (CI)

95% CI = (1 - 0.95) = 0.05

For a two-tailed test : 0.05 / 2 = 0.025

Z - score = 1.96

Error : (√[p(1 - p) / n])*z

1.96 * √0.241(1-0.241)/1000

1.96* √0.000182919

1.96 * 0.0135247

= 0.0265085

Boundary :

(0.241 - 0.0265085), (0.241 + 0.0265085)

(0.2144915, 0.2675085)

F) The sample can be said to be representative of the total population since the sampling was performed and participants were chosen at random.
