PLEASE HELP!!! 50 POINTS!!

Mathematics
1 answer:

Answer:

IV- Their Diet              DV- Blood Pressure

Step-by-step explanation:

You can always think of your IV as the variable that's gonna "change" and your DV will be "measured". So ask yourself what's being changed, and measured?

Well we can infer that blood pressure is what the researcher is measuring. We know this because his whole goal in the experiment is to see a change.  

And IV we can infer will be what's changing. I believe their diet would be what's changing.

I hope this helps! Try and use the replacement words for the IV and DV, they help a lot!!

Thanks for letting me help!!

What is the equation of the function in slope-intercept form?
Rasek [7]
To write this equation, you need use the formula y=mx+b.

m represents the slope and b represents the y intercept.

The y intercept is the point where the line touches the y axis. In this case, the y-intercept is 1.

The slope is just rise over run from one coordinate to another. The slope is 2/-1 which could be simplified as -2. The slope just means that we are going up 2 and left 1 to get to a new coordinate.

The equation is y=-2x+1

Have a good day! :)

Find the average rate of change of the function over the given interval.
Minchanka [31]

Answer:

Average rate of change = 20.2

Rate of change at the left endpoint :   f' (5) = 4t = 20

Rate of change at the right  endpoint : f' (5.1) = 4*5.1 = 20.4

Step-by-step explanation:

The average rate of change of the function

F(t) = 2t^2 - 1 ,  [ 5,5.1 ]

solution

\frac{f(5.1)-f(5)}{5.1 - 5} = \frac{2*(5.1)^2-1-(2*5^2-1)}{0.1}   = [ 2 ( 26.01 - 25 ) / 0.1 ]

= 2.02 / 0.1 = 20.2

Rate of change at the left endpoint :   f' (5) = 4t = 20

Rate of change at the right  endpoint : f' (5.1) = 4*5.1 = 20.4

victor needs 300 feet of rope.The rope he wants to buy is sold by yards.He knows that there are 3 feet in 1 yard.How many yards
barxatty [35]

We need to convert 300 feet to yards.

We know,

3 feet = 1 yard

Hence,

300 feet * 1 yard/3 feet = 300/3 = 100 yards

He should buy 100 yards

Please solve both of these with how you solved them.
Paladinen [302]

Answer:

a. (2,5)

b. (14,15.5)

Step-by-step explanation:

a.

y=4x-3

y=-2x+9

Set both equations equal to each other to solve for x.

4x-3=-2x+9

6x=12

x=2

Plug in x to solve for y.

y=4x-3

y=4(2)-3

y=8-3

y=5

(2,5)

b.

y=(5/4x)-2

y=(-1/4x)+19

Set both equations equal to each other to solve for x.

(5/4x)-2=(-1/4x)+19

4((5/4x)-2=(-1/4x)+19)

5x-8=-x+76

6x=84

x=14

Plug in x to solve for y.

y=(5/4x)-2

y=(5/4(14))-2

y=17.5-2

y=15.5

(14,15.5)
