4. Compare/contrast the data sets below. Which data set has a range of 9, a mean of
VladimirAG [237]

Let's first find the mode of each data set.

Mode = the largest value - the smallest value.

A. 20 - 11 = 9

B. 31 - 5 = 26

C. 20 - 11 = 9

D. 15 - 6 = 9

B fails because its mode does not equal 9.

Let's find the mean of A, C, and D

The mean = the sum of all data values divided by the number of data values.

A. (11 + 11 + 13 + 15 + 20) / 5 = 14.2

C. (11 + 11 + 14 + 19 + 20) / 5 = 15

D. (6 + 10 + 14 + 15 + 15) / 5 = 12

Options A and D fail because their mean does not equal 15.

Let's find the median and mode of option C

Median = the value which falls into the middle of our data set

11, 11, 14, 19, 20 = 14

Mode = the value which appears most often

In option C, 11 appears twice and every other number appears once, therefore, 11 is the mode.

Which statement is true about the function f(x)= StartRoot x EndRoot?
Gelneren [198K]

The statement that is true is the third statement - The domain of the graph is all real numbers less than or equal to 0

<h3>Domain and Range of a Function</h3>

From the question, we are to determine the statement that is true about the given function.

The domain of a function consists of all the input values shown on the x-axis.

and

The range is the set of possible output values, which are shown on the y-axis

The given function is

f(x) = √-x

The possible input values for the given function is the set of all real numbers less than or equal to zero. That is, the domain of the function is the set of all real numbers less than or equal to zero.

The possible output value for the given function is the set of all real numbers greater than or equal to zero. That is, the range of the function is the set of all real numbers greater than or equal to zero.

Hence, the correct statement is the third statement - The domain of the graph is all real numbers less than or equal to 0

Does 0.9x+5.1x-7=2(2.5x-3) have no solution many solutions or one solution?
olganol [36]

Answer:

This equation has ONE unique solution, which is x = 1.

Step-by-step explanation:

Let's actually solve this equation, 0.9x+5.1x-7=2(2.5x-3).

Mult. all four terms by 10 to eliminate the fractions:

9x+51x-70=2(25x-30)

Perform the indicated multiplication:

9x+51x-70= 50x - 60

Combine like terms:  60x - 70 = 50x - 60  =>  10x = 10, and x = 1

This equation has ONE unique solution, which is x = 1.
