Answer:

1. 3. 4. 2.

Step-by-step explanation:

All the given linear relationships are given in slope-intercept form
y = mx + b (where m is the slope and b is the y-intercept).

The slope (gradient) of the line represents the rate of change. Therefore, we need to examine the slope of each relationship, and order them accordingly.

<u>Solution</u>

From least rate of change to greatest rate of change:

1. y = 2x + 7

3. y = 3x

4. y = 4x + 6

2. y = 5x - 3

A national dental association conducted a survey to find the average (mean) amount of time dentists spend on dental fillings per

eduard

Answer:

The probability of finding a sample mean less than 18 hours is 0.0082

Step-by-step explanation:

To find the probability of finding a sample mean less than 18 hours, we need to calculate the z-score of this sample mean 18. And the probability of finding a sample mean less than 18 hours is P(z<z(18)).

Z-score can be calculated as follows:

z(18)= $\frac{X-M}{\frac{s}{\sqrt{N} } }$ where

X is the sample mean (18 hours)

M is the average hours dentists spend per week on fillings (20 hours)

s is the standard deviation (10 hours)

N is the sample size (144)

Putting the numbers, we get:

z(18)= $\frac{18-20}{\frac{10}{\sqrt{144} } }=-2.4$

Using z- table we can find that P(z<z(18)) = 0.0082

The graph of the function f(x)=4/5 sqrt x is shown.<br> What is the domain of the function?

S_A_V [24]

Answer:

All real number greater than equal to zero.

Step-by-step explanation:

The function is given by

$f(x) = \frac{4}{5}\sqrt x$

The domain is defined as the input values so that the function is well defined.

here, the values of x should be all real number and zero also.

So, the correct option is (d).

What’s the median for 28,30,30,30,30,31,31,31,31,31,31,31,31

olya-2409 [2.1K]

Answer:

Step-by-step explanation:

The median is the number that we find in the middle of the data.

So if we have a sequence of {1,2,3}

Then 2 is the median

If we have a sequence of {1,2,3,4,5}

Then 3 is the median

We look in the middle of 28,30,30,30,30,31,31,31,31,31,31,31,31

and we find 31 in the middle.

Note:

If the middle is something with 2 terms in the middle like

1,2,3,4

Then the median is the average of the two middle terms which is

(2+3)/2 = 2.5
