-8,5,6,|-7|,8
5,6,8,-8,|-7|​

Answers

Answer:

-8, 5, 6 , |-7|, 8

Step-by-step explanation:

We can solve the absolute functions to make it easier to determine which set is from least to greatest

-8, 8, 6, 7, 5 x

7, -8, 8, 6, 5

-8, 5, 6, 7, 8

5, 6, 8, -8, 7

Therefore the group of order integers from least to greatest is -8, 5, 6 , |-7|, 8

Which set of ordered pairs could be generated by an exponential function

Answers

The required set of ordered pairs are (0, 1), (1, 3), (2, 9), (3, 27). The correct option is (D).

What is an exponential function?

An exponential function can be represented as y = aˣ. When x = 0, y = a⁰ = 1. The range of an exponential function is from zero to infinity for a > 0.

It is clear from the given options that, only options (B) and (D) satisfies the general expression y = aˣ at x = 0.

Now, both these options can be examined one by one as follows,

Option (B),

The ordered pairs are given as (0, 1), (1, 2), (2, 5), (3, 10).

Substitute the values in the general expression y = aˣ, first two pair are satisfied for a = 2 but the remaining two are not.

Option (D),

The ordered pairs are given as (0, 1), (1, 3), (2, 9), (3, 27).

Substitute the values in the general expression y = aˣ, all the pairs are satisfied for a = 3.

Thus, the correct option is found.

Hence, the set of ordered pairs which could be generated by an exponential function are (0, 1), (1, 3), (2, 9), (3, 27).

Find the distance between the pair of parallel lines, y = -2x+1 & y = -2x+16.

Answers

Given \ the \ equations \ of \ two \ non-vertical \ parallel \ lines:\n\ny = mx+b_1\ny = mx+b_2\n\nthe \ distance \ between \ them \ can \ be \ expressed \ as : \n\nd= (|b_(1)-b_(2)|)/( √( m^2+1) )

A normal distribution has a mean of 0.40 and standard deviation of 0.028. What percentage of observations will lie between 0.372 and 0.428?

Answers

Solution:
To evaluate for P(0.372<x<0.428) we shall proceed as follows:
z-score is given by:
z=(x-μ)/σ
thus when x=0.372:
z=(0.372-0.4)/0.028
z=-1
thus
P(x<0.372)=P(z<-1)=0.1587

when x=0.428
z=(0.428-0.4)/(0.028)=1
P(x<0.428)=P(z<1)=0.8413
thus
P(0.372<x<0.428) =P(z<1)-P(z<-1)=0.8413-0.1587=0.6826

Final answer:

To find the percentage of observations between two values in a normal distribution, we can convert the values to z-scores and use a z-table to find the corresponding areas. In this case, the percentage of observations between 0.372 and 0.428 is 68.26%.

Explanation:

To find the percentage of observations that will lie between 0.372 and 0.428 in a normal distribution with a mean of 0.40 and standard deviation of 0.028, we need to find the area under the curve between these two values.

Using a standard normal distribution table or z-table, we can convert the values to z-scores by subtracting the mean and dividing by the standard deviation. The z-score for 0.372 is (0.372 - 0.40) / 0.028 = -1, and the z-score for 0.428 is (0.428 - 0.40) / 0.028 = 1.

By looking up the corresponding area for these z-scores in the z-table, we find that the area to the left of -1 is 0.1587 and the area to the left of 1 is 0.8413. To find the percentage between -1 and 1, we subtract the smaller area from the larger area: 0.8413 - 0.1587 = 0.6826 or 68.26%.
