Race relations: A New York Times/CBS poll surveyed 1,027 adults nationwide about race relations in the United States. Of the sam
Montano1993 [528]

Answer:

D. We are 95% confident that the proportion of all Americans who say that race relations in this country are generally bad is between 58% and 64%.

Step-by-step explanation:

The 95% confidence interval refers that 95% of data is correct with respect of the population

Given that 95% confidence interval is (0.58, 0.64)

So based on this, the option D is correct as it shows the right thing with regard to 95% confidence interval

Therefore all the other options are incorrect as the first option is of probability, the second option is the sample, and the third option is of statement form i.e not standardized.

It is true that the product of two consecutive even integers are always one less than the square of their average.

<u>Step-by-step explanation</u>:

Let the two consecutive odd integers be 1 and 3.

  • The product of 1 and 3 is (1\times3)=3
  • The average of 1 and 3 is (1+3)/2 =4/2 = 2
  • The square of their average is (2)² = 4

∴ The product 3 is one less than the square of their average 4.

Let the two consecutive even integers be 2 and 4.

  • The product of 2 and 4 is (2\times4)=8
  • The average of 2 and 4 is (2+4)/2 =6/2 = 3
  • The square of their average is (3)² = 9

∴ The product 8 is one less than the square of their average 9.

Thus, It is true that the product of two consecutive even integers are always one less than the square of their average.

Mitch used 1 4 pounds of beef to make 3 4 liters of beef strogonoff. If Mitch's recipe is for 1 liter of beef strogonoff, how ma
iren [92.7K]

option B) 3 pounds of beef is needed to make 6 times the recipe.

<u>Step-by-step explanation</u>:

<u>step 1 </u>:

Mitch used 14 pounds of beef = 34 liters of beef strogonoff

'x' pounds of beef = 1 liter of beef strogonoff

<u>step 2</u> :

Rate = No. of pounds / No. of liters

(14 pounds / 34 liters) = (x pounds / 1 liter)

x = 14/34

x = 0.412

1 liter of beef strogonoff = 0.412 pounds of beef

<u>step 3</u> :

To make 6 times the recipe = 6 \times 0.412

                                              = 2.5 pounds of beef ( approximately 3 pounds)
