3 0

Answer:

Yes

Step-by-step explanation:

Substitute the values.

x = 5

y = 6

y < 2x + 4

6 < 2(5) + 4

6 < 10 + 4

6 < 14

6 is indeed less than 14

Crazy boy [7]
<span>a) Explain how you would carry out a completely randomized experiment for the study
- The volunteers will be listed alphabetically and assigned a number from 1 to n. Using the random selection method, select the persons at half of the population and assign them as the treatment group getting the new medication. The remaining population will be under the current medication. Measure everyone's cholesterol level and apply the needed medication for several months. Apply the process and compare the results.

- The best design would be to block by cholesterol levels (ie, High, Moderately High, Very High)

</span> c) Can the experimental design in (b) be carried out in a double blind manner? 
Yes, everyone in each block randomly assigned to a treatment so volunteers are not aware of the medication they are receiving while administrators do not know what medication they are giving.

Need help <br><br> Pls explain
Crank

Given:

The graph of a line.

To find:

The equation of the line.

Solution:

From the given graph, it is clear that the line passes through the points (0,-2) and (-6,8). So, the equation of the line is:

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

y-(-2)=\dfrac{8-(-2)}{-6-0}(x-0)

y+2=\dfrac{10}{-6}x

y+2=-\dfrac{5}{3}x

Subtract 2 from both sides.

y=-\dfrac{5}{3}x-2

Therefore, the equation of the line is y=-\dfrac{5}{3}x-2.

Which transformations of the graph of 1x) = -4*x result in the graph of f(x) = 4x+3?
KATRIN_1 [288]

First we need to take the - signal

So the difference between the graphs y = -4x and y = 4x is that they are mirrored by the y-axis

Now we have the graph y = 4x and want the graph y = 4x + 3

We just need to move the graph y = 4x 3 units to the left

So the transformations we need is to move it 3 units to the left and to mirror it by the y-axis

Find the range of the parent function below y=x^2
marusya05 [52]

you don't show the graph, but graphing y=x^2 it is a U shaped line that starts at (0,0) and the lines go upwards on both sides of the Y axis,

 This means all real numbers above 0 and 0 will solve it

 so the range is y≥0

The percentage of people under the age of 18 was 23.5% in New York City, 25.8% in Chicago, and 26% in Los Angeles.
Hatshy [7]

Answer:

0.0158 = 1.58% probability that all of them are under 18.

Step-by-step explanation:

Probability of independent events:

If three events, A, B and C are independent, the probability of all happening is the multiplication of the probabilities of each happening, that is:

P(A \cap B \cap C) = P(A)P(B)P(C)

The percentage of people under the age of 18 was 23.5% in New York City, 25.8% in Chicago, and 26% in Los Angeles.

This means that P(A) = 0.235, P(B) = 0.258, P(C) = 0.26

If one person is selected from each city, what is the probability that all of them are under 18?

Since the three people are independent:

P(A \cap B \cap C) = 0.235*0.258*0.26 = 0.0158

0.0158 = 1.58% probability that all of them are under 18.
