Solve for y :

3y = 9 (8 - y)

3y = 72 - 9y

Which of the ratios below is equivalent to 2:1? Select all that apply.

A) 6:4
B) 8:4
C) 10:5
D) 6:12
E) 6:3

Answers

The ratios below that are equivalent to 2:1 is 8:4, 10:5 and 6:3. That is options B, C, and E.

To find the ratio of a given two quantities how many times one quantity is greater or smaller than the other.

Therefore in option B, when 8:4 is simplified by division,

8/4 = 2/1 = 2:1

Therefore, in option C, when 10:5 is simplified by division,

10/5 = 2/1 = 2:1

Therefore, in option E, when 6:3 is simplified by division, 6/3 = 2/1 = 2:1

Therefore, the ratios below that are equivalent to 2:1 is 8:4, 10:5 and 6:3.

A square and a rectangle have the same perimeter. The square has a side length of 8x units. The rectangle has a length of (4x + 10) units and a width of 14 units. What will be the perimeter of both the rectangle and square?

A. 34 units
B. 60 units
C. 64 units
D. 2 units

Answers

Answer:

the answer is d(2 units)

Answer:

C 64 units

Step-by-step explanation:

P = 2L + 2W

square

2(8x) + 2(8x) = 16x + 16x = 32x.  

rectangle

2(4x + 10) + 2(14) = 8x + 20 + 28= 8x + 48

32x = 8x + 48

-8x    -8x

24x = 48

divide both sides by 24

x = 2

P = 32(2) = 64

Consider random samples of size 50 from a population with proportion 0.35.
Find the mean and standard error of the distribution of sample proportions.
Round your answer for the mean to two decimal places, and your answer for the standard error to three decimal places.

Answers

Answer:

The mean is  [tex]\mu_{\^ p } = p = 0.35[/tex]    

The standard error  is  [tex]SE = 0.06745[/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  50  

    The population proportion is [tex]p = 0.35[/tex]

Generally given that the sample size is large enough , then the mean of the distribution is  mathematically represented as

          [tex]\mu_{\^ p } = p = 0.35[/tex]    

Generally the standard error of the distribution is mathematically represented as

        [tex]SE = \sqrt{\frac{p (1- p )}{n} }[/tex]

=>     [tex]SE = \sqrt{\frac{0.35 (1- 0.35 )}{50} }[/tex]

=>     [tex]SE = 0.06745[/tex]

One tank is filling at a rate of 3/4 gallons per2/3 mins. A second tank is filling at a rate of 5/8 gallons per 1/2 mins. Which tank is filling faster?

Answers

9514 1404 393

Answer:

  2nd tank

Step-by-step explanation:

The rate of filling, in gallons per minute, is found by dividing gallons by minutes.

Tank 1

  (3/4 gal)/(2/3 min) = (3/4)(3/2) gal/min = 9/8 gal/min

Tank 2

  (5/8 gal)/(1/2 min) = (5/8)(2/1) gal/min = 10/8 gal/min

10/8 gal/min is more than 9/8 gal/minute.

The second tank is filling faster.
