Substitute each value in:

x < 3

y > 1

5 < 3

2 > 1

0 < 3

0 > 1

2 < 3

0 > 1

The number of lattes sold daily by two coffee shops is shown in the table.

Gre4nikov [31]

Answer:

The correct option is B.

Step-by-step explanation:

The number of lattes sold daily by two coffee shops is shown in the table.

The data set for shop A is

55, 52, 56, 48, 57, 30, 45, 41

Arrange the data in ascending order.

30, 41, 45, 48, 52, 55, 56, 57

Mean of shop A is

$Mean=\frac{\sum x}{n}=\frac{30+41+45+48+52+55+56+57}{8}=48$

$Median=\frac{(\frac{n}{2})th+(\frac{n}{2}+1)th}{2}=\frac{48+52}{2}=50$

The data set for shop B is

45, 42, 57, 48, 11, 10, 46, 43

Arrange the data in ascending order.

10, 11, 42, 43, 45, 46, 48, 57

Mean of shop A is

$Mean=\frac{\sum x}{n}=\frac{10+11+42+43+45+46+48+57}{8}=37.75$

$Median=\frac{(\frac{n}{2})th+(\frac{n}{2}+1)th}{2}=\frac{43+45}{2}=44$

Both data distribution are not symmetric, so it is better to describe the centers of distribution in terms of median for both coffee shops. Therefore the correct option is B.

Which of the following functions is graphed below

Gnoma [55]

Remark

A function is defined as 1 y value per x value. The y values can be the same for 2 x values, but the x values must have just 1 value associated with it. I am describing a vertical line test for a function. This is a function.

A 1 to 1 function means that the function obeys the horizontal line test. That means that for every x there is only 1 y value.

This graph is both a function and a 1 to 1 function. So the answer is A.

None of the other answers are this complete and one of them is wrong.

B is wrong. It is a 1 to 1 function.

C is wrong. The graph is a function.

D is wrong. No y values are duplicated.

The sum of two numbers is equal to 70. Which of the following functions can be use to find the product of the two numbers if one

Temka [501]

Let x=number 1 let y=number2
there sum is equal to 70
then

number1+number2=70

substituting

x+y=70

y=70-x
let there product will be p
p=xy
substituting
p=x(70-x)
which is choice c
