Answer:

y = -1

x = 6

Step-by-step explanation:

y = -x + 5

2x + y = 11

then:

2x + (-x+5) = 11

2x - x + 5 = 11

x + 5 = 11

x = 11 - 5

x = 6

y = -x + 5

y = -6 + 5

y = -1

Check:

2x + y = 11

2*6 + (-1) = 11

12 - 1 = 11

a storybook is sold at a discount of 20%. If the discount is $3, what is the selling price of the storybook

Neporo4naja [7]

Answer:

Step-by-step explanation: the discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.

We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.

0.2x = 3

Divide both sides by 0.2.

x = 3/0.2

x = 15

The regular price is $15.

The histogram shows the distribution of heights, in inches, of 100 adult men.

pishuonlain [190]

Based on the histogram, the interquartile rangle of the distribution is 5 inches.

<h3>What is the interquartile range?</h3>

The interquartile range is the difference between the third quartile of a data set and the first quartile of the data set.

First quartile = 1/4 x ( n + 1)

= 101 / 4 = 25.25

25.25 on the histogram is 66

Third quartile = 3/4 x (n + 1)

303 / 4 = 75.75

75.75 on the histogram is 71

Interquartile range = 71 - 66 = 5

A nationwide poll asked a random sample of US adults the question, “Are you in favor of making Election Day a federal holiday?”

forsale [732]

Answer: point estimate = 0.67 and Margin of error = 0.03 .

Step-by-step explanation:

For confidence interval,

Lower limit = point estimate - margin of error

Upper limit = point estimate + margin of error

Given confidence interval: (0.64, 0.70)

i.e. Lower limit = 0.64

Upper limit = 0.70

i.e. point estimate - margin of error= 0.64 (i)

point estimate + margin of error= 0.70 (ii)

Adding (i) and (ii) , we get

2( point estimate) = 1.34

⇒ point estimate = 0.67

Eliminate (i) from (ii) , we get

2( Margin of error ) = 0.06

⇒ Margin of error = 0.03

Hence, point estimate = 0.67 and Margin of error = 0.03 .
