1. Yes they are congruent. You translate AB to move it over to CD. Specifically, shift 2 units to the right.

2. No, they are not congruent. QR is longer than MN. Congruent segments must be the same length.

3. No, they are not congruent. At first glance, they seem to be congruent after translation and reflection. However, XY is longer than UV, and those legs should be the same length for a pair of congruent triangles to be possible.

4. Yes they are congruent. You translate triangle ABC to move it over to triangle DEF (shift 1 to the left, 3 down).

Assume that it is true that people can not tell the difference between Coke and Pepsi. If a sample of 15 people participated in

pantera1 [17]

Answer:

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they can tell the difference between Coke and pepsi, or they cannot. The probability that a person has o telling the difference between Coke and pepsi is independent from each other. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to the normal distribution if

$np \geq 10$

and

$n(1-p)\geq 10$

In this problem, we have that:

$n = 15$

First condition

$np \geq 10$

$15p \geq 10$

$p \geq \frac{10}{15}$

$p \geq \frac{2}{3}$

Second condition

$n(1-p) \geq 10$

$15(1-p) \geq 10$

$15 - 15p \geq 10$

$-15p \geq -5$

Multiplying by -1

$15p \leq 5$

$p \leq \frac{1}{3}$

p cannot be at the at the same time greather than 2/3 and lesser than 1/3. So we cannot assume that the sampling distribution of the proportion of people that correctly chose Pepsi is normal.
