Hi there!

»»————-　★　————-««

I believe your answer is:

Scatterplot B

»»————-　★　————-««

Here’s why:

A scatterplot with a correlation coefficient of 0 would show no relationship between the variables at all. It will not form any line at any strength.
Scatterplot B best resembles this. Notice how the plots do not resemble a line; they are just 'scattered' all over.

The sum of the roots of 3x 2 + 11x - 4 = 0 is -11/3 -4/3 11/3 4/3

givi [52]

Answer:

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

$ax^2+bx+c=0$ .... (1)

Then the sum of the roots is -b/a and the product of roots is c/a.

The given equation is

$3x^2+11x-4=0$ ... (2)

From (1) and (2) we get a=3, b=11 and c=-4.

The sum of roots is

$\frac{-b}{a}=-\frac{11}{3}$

The sum of roots is $-\frac{11}{3}$ .

Therefore the correct option is 1.

How do you do number 24?

elena-14-01-66 [18.8K]

Answer: k = 4

---------------------------------------------
---------------------------------------------

Explanation:

The piecewise function is essentially two different functions joined together. In this case,

h(x) = kx if 0 <= x < 1
OR
h(x) = x+3 if 1 <= x <= 5

The value of x determines which piece we use.

The two pieces will join together to be continuous only if the y value is the same for x = 1.

Plug x = 1 into the first piece and we get
h(x) = k*x
h(1) = k*1
h(1) = k

Do the same for the second piece
h(x) = x+3
h(1) = 1+3
h(1) = 4

Set the two results (k and 4) equal to each other and we get k = 4.

The length of a rectangle is 4 centimeters more than the width.if both the width and the length were tripled,the area would be 1

Sonbull [250]

Since both the length and the width are tripled, the area will be nine times larger. To counter this, divide by nine. 108/9=12 Divide this by 2 to get one length and one width. You get 6. 1+5=6 and 1 is 4 smaller than 5, so the width of this rectangle is 1 cm and the length is 5 cm.
