Answer:

True.

Step-by-step explanation:

We have been given a statement and we are asked to determine whether our given statement is true or false.

Statement:

A z-score of 1.0 corresponds to a value one standard deviation from the mean.

We know that z-score of a data set represents how many standard deviation a data point is above or below mean.

Since the z-score of a data set is 1.0, so it represents that the data is 1 standard deviation above mean.

Therefore, our given statement is true.

stich3 [128]

Answer:

√95 cm

Step-by-step explanation:

To solve, you need to use the pythagorean theorem, or a^2 + b^2 = c^2

The hypotenuse is the c and let one leg be b. You can write:

a^2 + 7^2 = 12^2

a^2 + 49 = 144

Now, you need to solve for a:

a^2 = 144 - 49

a^2 = 95

a = √95 cm, or about 9.75cm

Which graph represents the function f(x) = |x|? Image for option 1 Image for option 2 Image for option 3 Image for option 4

Lemur [1.5K]

Answer:

The correct option is 4.

Step-by-step explanation:

The given function is,

It is a modulus function and its parent function is,

In a function,

If k>1, then the graph of g(x) stretch vertically and if k<1 then the graph of g(x) compressed vertically.

Since k is , therefore the shoes the vertical compression.

put x=0 in the given function.

Put x=3.

Therefore the graph passing through (0,0) and (3,1).

So the fourth option is correct.

Hope this helps :)

7 3/10 as a percentage

Harlamova29_29 [7]

7 3/10 in percent would be $7.3 \times 100 = 730$ %

730%

percent means over 100

So... 730% = 730/100 = 7.3
