It has been determined that 60% of the people in a certain midwest city who are responsible for preparing the evening meal have

natali 33 [55]

Answer:

Random sample, $np \geq 10$ and $n(1-p) \geq 10$ , so yes, both conditions were satisfied.

Step-by-step explanation:

60% of the people in a certain midwest city who are responsible for preparing the evening meal have no idea what they are going to prepare as late as 4PM in the afternoon.

This means that $p = 0.6$

A recent survey was conducted from 1000 of these individuals.

This means that $n = 1000$

Also, a random sample, so the first condition was satisfied.

The sample size must be large (so that at least 10 or more successes and failures).

$np = 1000*0.6 = 600 \geq 10$

$n(1-p) = 1000*0.4 = 400 \geq 10$

So yes, both conditions were met.

Suppose you construct lines L, M, and N so that L is perpendicular to M and L is parallel to N. which of the following is true.

Blizzard [7]

In the question we are given three lines L,M and N such that:

Line L is perpendicular to M

and line L is parallel to line N

so the option is (C) M is perpendicular N

Step-by-step explanation

We are given three lines L,M and N such that:

Line L is perpendicular to M
Line L is parallel to line N

We know that when one line parallel to the second line and is perpendicular to the third line then the second line is also perpendicular to the third line.

So,the answer is (C) M is perpendicular N

Lin has 4 pinecones and some acorns.

frozen [14]

Answer:

Lin has 11 acorns ⇒ answer D

He subtract 4 from 7 instead of add 4 to 7

Step-by-step explanation:

- Lin has 4 pinecones and some acorns

- She has 7 fewer pinecones than acorns

- The meaning of 7 fewer pinecones than acorns is the number of the

pinecones is less than the number of acorns by 7

∵ She has 4 pinecones

∵ She has 7 fewer pinecones than acorns

- The number of pine cones is less than the number of acorns by 7

∴ 4 = number of acorns - 7

- Add 7 to both sides

∴ 11 = number of acorns

* Lin has 11 acorns

- Tom choose answer A which is 3

- He made a mistake in the equation

- He put ⇒ number of the acorns = 7 - 4 not 7 + 4

∴ number of acorns = 3

* He subtract 4 from 7 instead of add 4 to 7
