Naddik [55]

Answer:

C. II only

Step-by-step explanation:

Basically all you need do is plug these answers in and if the complete the inequality to make a true statement.

Yes i know no body want to do that but that whats need to be done lol.

once i plug 7 12/7+8 = 12.83

12.83>20

is incorrect

so we need continue

7*2.5+8>20

7*2.5= 17.5

17.5+8= 25.5

25.5>20

this a true statement

so we know 2.5 is an answer

now we need plug in -3

7*-3= -21

-21 +8 = -13

-13>20

this is incorrect

By convention, the independent variable is arrayed along the ____ in a scattergram. regression line calibration line vertical ax

babunello [35]

Answer:

Horizontal axis

Step-by-step explanation:

By convention, the independent variables is arrayed along the Horizontal axis (abscissa) in a scattergram.

The stcattergram has two dimensions

The X (independent) variable is arrayed along the horizontal axis.
The Y(dependent) variable is arrayed along the vertical axis.
Each dot scattergram is case in data set.
The dot is placed at the intersection cases scores on X and Y.

Can you help me with this.

Ugo [173]

Answer:

1. x = 2

y = 1

2. x = 3 or 6 (Mistake or typo in problem)

3. y = 13

4. x = 7

y = 15

5. x = 4

Step-by-step explanation:

1. 6x - 3 = x + 7, 5x = 10, x = 2

3y + 2 = y + 4, 2y = 2, y = 1

2. There is most likely a typo. Either 8x = 24 and x = 3 or 2x + 10 = 3x + 4 and x = 6

3. 5y -3 = 2y + 36, 3y = 39, y = 13

4. 8y + 11 + 3y + 4 = 180, 11y + 15 = 180, 11y = 165, y = 15

7x = 3y + 4 = 49, x = 7

5. 7x - 10 = 4x + 2, 3x = 12, x = 4

The distribution of the diameters of a particular variety of oranges is approximately normal with a standard deviation of 0.3 in

In-s [12.5K]

Answer:

The correct answer is C.

Step-by-step explanation:

$67^{th}$ percentile is represented as the value of probability in the norma distribution.

We look for a z-value with a left-tail of 0.67.

z=0.44

where,

$z=\frac{x-M}{SD}$

M: mean

SD: standar deviation

x=z×SD+M=0.44×0.3+M=M+0.132

The diameter of an orange at the 67^th percentile is 0.132 inch above the mean.

Write a function, ???? ,in terms of another function, ????, such that the graph of ???? is a vertical shrink of the graph ???? b

Liula [17]

Answer:

See explanation below.

Step-by-step explanation:

Let's assume that we have an original function $f(x)$ and let's suppose that we have a constant $c>0$ and if we define this new function:

$h(x) = c f(x)$

We see that if c>1 the dunction would be vertically stretched by c units.

And if $0$ we see that we will have a vertically shrinking by a factor of c units

So for example we can use the following function:

$f(x) = x^2$

For this case our constant is c=0.75 and we can define the new function like this:

$h(x) = 0.75x^2$

We will see if we plot the two figures that we have a vertical shrinking of 0.75 units.
