Answer:

Negative Correlation

Strong Correlation

Linear

Step-by-step explanation:

The points slope downward, and downward slopes = negative

This is a strong correlation because the points are in a distinct line, not scattered.

This is Linear because it is a straight line.

-Good luck on the exam!

Determine f(9/2) for the function f(x)=3x-5

ANEK [815]

Answer:

f(9/2) = 17/2

Step-by-step explanation:

f(x) = 3x-5

let x=9/2

f(9/2) = 3*9/2 -5

f(9/2) = 27/2 - 5

get a common denominator

f(9/2) = 27/2 - 10/2

f(9/2) = 17/2

Hector is dividing students into groups for a nature hike. He wants to divide the boys and girls so that each group has the same

Zolol [24]

Answer: The students can be divided into 7 groups.

Each group will have 3 boys and 8 girls.

Step-by-step explanation:

There are 21 boys and 56 girls.

To divide them so that each group has the same number of both boys and girls.

We find GCD(21,56).

21 = 3 x 7

56 = 2 x 2 x 2 x 7

GCD (21,56) = 7

So, the students can be divided into 7 groups.

Number of girls in each group = $\dfrac{56}{7}=8$

Number of boys in each group = $\dfrac{21}{7}=3$

So, each group will have 3 boys and 8 girls.

G(x) = x - 2x^2<br><br>g(-1)

Goshia [24]

(-3).
We plug (-1) for x in g(x) and we get:
(-1) - 2(-1)^2.
To simplify, (-1)^2 turns to just 1. since a negative times a negative gives a positive.
Then, we have (-1) - 2(1) or (-1) - 2 or -1 - 2.
This is then -3

The area of the circle above is 314 units2. What is the circumference of the circle? use 3.14

aleksandrvk [35]

Answer:

$r =\sqrt{\frac{314 units^2}{3.14}} = 10 units$

And the circumference is given by this formula:

$C = 2\pi r$

And replacing the value fo r we got:

$C = 2\pi *10 units = 62.8 units$

And then the final answer would be 62.8 units for the circumference.

Step-by-step explanation:

For this case we know that the area for a circle is given by:

$A = \pi r^2$

And we know that $A = 314 units^2$

We can find the radius from the previous formula like this:

$r^2 = \frac{A}{\pi}$

$r^2 = \frac{314 units^2}{\pi}$

$r =\sqrt{\frac{314 units^2}{3.14}} = 10 units$

And the circumference is given by this formula:

$C = 2\pi r$

And replacing the value fo r we got:

$C = 2\pi *10 units = 62.8 units$

And then the final answer would be 62.8 units for the circumference.
