Given that (3,-1) is on the graph of f(x), find the corresponding point for the function f(3x)

Katarina [22]

Answer:

(1, -1)

Step-by-step explanation:

You have the point ...

(3, f(3)) = (3, -1)

The corresponding point on the horizontally compressed graph will be ...

(3x, f(3x)) = (3, -1)

(x, f(3x)) = (1, -1) . . . . . the first coordinate of the given point is divided by 3

Assume that adults have IQ scores that are normally distributed with a mean of 96.296.2 and a standard deviation 20.520.5. Find

Sergeeva-Olga [200]

Answer:

The first quartile of the IQ scores of adults is 82.26.

Step-by-step explanation:

The first quartile is the value that is greater than 25% of the observations and less than 75% of the observation.

The formula to compute the first quartile (Q₁) of a Normal distribution is:

$Q_{1}=\mu-0.68\sigma$

The mean and standard deviation of the IQ scores of adults are:

$\mu=96.2\\\sigma=20.5$

Compute the first quartile value as follows:

$Q_{1}=\mu-0.68\sigma=96.2-(0.68\times20.5)=82.26$

Thus, the first quartile of the IQ scores of adults is 82.26.

Please help.

yan [13]

131 3/4 ⇒ 115 5/8 ⇒ 5 2/3

Subtract 131 3/4 by 115 5/8.

131 3/4 ⇒ 131 6/8
131 6/8 - 115 5/8 = 16 1/8

Now add 16 1/8 + 5 2/3 and this will give you how much weight she lost in all.

16 1/8 ⇒ 16 3/24
5 2/3 ⇒ 5 16/24
16 3/24 + 5 16/24 = 21 19/24

Felice lost 21 19/24 pounds in all.
