To determine the effect their salespersons have on purchases, a department store polled 700 shoppers regarding whether or not th

Soloha48 [4]

Answer:

a) p = 352/700 = 0.5029

b) p = 348/700 = 0.4971

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

There are 700 shoppers.

151 + 201 = 352 were happy with the service received.

133 + 215 = 348 were not happy with the service received.

(a) A shopper was happy with the service received.

352 happy out of 700

p = 352/700 = 0.5029

(b) A shopper was unhappy with the service received.

348 unhappy out of 700

p = 348/700 = 0.4971

Express log2 6 + log2 7 as a single logarithm. A. log2 42 B. log2 √ 42 C. log2 7/6 D. log2 6/7

never [62]

Answer:

A. $\log _2\left(6\right)+\log _2\left(7\right)=\log _2\left(42\right)$

Step-by-step explanation:

To express $\log _2\left(6\right)+\log _2\left(7\right)$ as a single logarithm you must apply the log rule:

$\log _c\left(a\right)+\log _c\left(b\right)=\log _c\left(ab\right)$

So,

$\log _2\left(6\right)+\log _2\left(7\right)=\log _2\left(6\cdot \:7\right)$

Multiply the numbers: $6\cdot \:7=42$

$\log _2\left(6\right)+\log _2\left(7\right)=\log _2\left(42\right)$

What is the measure of angle x?

arsen [322]

Answer:

x° = 83°

Step-by-step explanation:

All angles in a triangle (any kind of triangle: right, isosceles, equilateral etc.) add up to 180 degrees.

So, if we are given the ABC triangle, then:

angle A + angle B + angle C = 180°

In this particular case, we are given values of two angles, so using the previous relation, we can write:

x° + 44° + 53° = 180°

Now, it's easy to find x°:

x° = 180° - 44° - 53°

x° = 83°

The heights of students in a class are normally distributed with mean 55 inches and standard deviation 5 inches. Use the Empiric

maks197457 [2]

Answer: c)[50,60]

Step-by-step explanation:

The Empirical rule says that , About 68% of the population lies with the one standard deviation from the mean (For normally distribution).

We are given that , The heights of students in a class are normally distributed with mean 55 inches and standard deviation 5 inches.

Then by Empirical rule, about 68% of the heights of students lies between one standard deviation from mean.

i.e. about 68% of the heights of students lies between $\text{Mean}\pm\text{Standard deviation}$

i.e. about 68% of the heights of students lies between $55\pm5$

Here, $55\pm5=(55-5, 55+5)=(50,60)$

i.e. The required interval that contains the middle 68% of the heights. = [50,60]

Hence, the correct answer is c) (50,60)
