The health of the bear population in yellowstone national park is monitored by periodic measurements. a sample of 54 bears has a mean weight of 182.9 lb. assuming the standard deviation is known to be 121.8lb find a 99% confidence intreval estimate

Answers

Answer 1
Answer: The 99% confidence interval will be found as follows:
x_bar +/- z(σ/√n)
where
z- z-score
σ-sigma
n=sample size
thus from the information given we shall have:
182.9+/-2.58(121.8/√54)
=182.9+/-42.7632
=225.6632 or 140.1368

Julio's dad owns a restaurant. He bought 9 dozen potatoes to make french fries. He needs 7 potatoes for a large order of fries. How many large orders of fires will he be able to make?I multiplied 9x12=108
then divided 108/7
I got 15 with 3 left over. Is this right?

Answers

Answer:

  yes, your math is correct

  15 large orders of fries can be made

Step-by-step explanation:

There are two questions here: one in the question you're trying to answer, and one that you have asked about your math. Hence, there are two answers here.

__

9 dozen divided by 7 is ...

  9·12/7 = 15 3/7

Julio's dad will be able to make 15 large orders of fries.

Three students were given the expression shown and were asked to take a common factor out of two of the terms. Use the drop-down menus to complete the statements about whether each student's answer is an equivalent expression. Then choose an expression that is equivalent.

Answer:

Step-by-step explanation:

Given: 4 - 9x +21

Factorizing this expression, we have;

              4 -3(3x - 7)

i. Chang's expression: 4 - 3(3x + 7)

This is not an equivalent expression, because by expansion of the bracket, the expression gives: 4 -9x -21

ii. Benjamin's expression: 4 + 3(3x + 7)

This is not an equivalent expression, because by expansion of the bracket, the expression gives: 4 +9x +21

iii. Habib's expression: 4 + 12x

This is not an equivalent expression, because the expression is not related to the given question

Comparing the three student's answers with the appropriate expression, none of the student's is an equivalent expression.

This expression that is  equivalent to the given question is;

            4 -3(3x - 7) = 4 -9x + 21
