Answer:

The correct answer is D) 2/11

Step-by-step explanation:

In order to find this, we must write out all the combinations of rolls that have a 4 in them.

4-1

4-2

4-3

4-4

4-5

4-6

1-4

2-4

3-4

5-4

6-4

There are 11 total options here. Now we need to find how many add up to 6. Only 2-4 and 4-2 add up to 6. So we know 2 out of 11 add up to 6.

In the function y=1/2x^2 , what effect does the number 1/2 have on the graph, as compared to the graph of the function y=x^2 ?

Masja [62]

Answer:

D isn't the correct answer. It's "It shrinks the graph vertically to 1/2 its original height."

Step-by-step explanation:

I'm not sure why though this is right because I graphed it, and I don't see how that could be the right answer.

Find the perimeter of triangle CDE. Round to the nearest tenth.

nevsk [136]

Here's how you do it: you find all the distances between the three points and add them together to calculate the perimeter of the triangle. To calculate for the distance between two points, the formula is

d = √[(x2 - x1)² + (y2 - y1)²]

So, just take two points, assign x1 and x2 with corresponding y1 and y2, then you get the answer.

Points: D(1,4), E(3,-2), C(-3,1)

After substituting the answers would be:
DE = 6.3 units
CE = 6.7 units
CD = 5 units

Perimeter = 6.3 + 6.7 + 5
Perimeter = 18 units

There are 7 gallons of black paint available to motorola. If 5/9 gallons is used each run, How many runs can we paint?

nadya68 [22]

There are 7 gallons of black paint available to motorola. If 5/9 gallons is used each run. To find the amount of runs you can paint, you have to divide the total by the amount for each run.

$7 \div \frac{5}{9}$

When dividing fractions, you have to keep, change, and flip.

$Keep\ 7 \\ Change\ \div\ to\ \times \\ Flip \frac{5}{9} = \frac{9}{5}$

Your new equation is:

$7 \times \frac{9}{5}$

Multiply:

$7 \times \frac{9}{5} = \frac{63}{5} = 12 \frac{3}{5}$

You can paint $12 \frac{3}{5}$ or $12.6$ runs.

Nana76 [90]

Answer:

For the shape of the distribution of the sample proportion to be approximately normal, it is required that np (1 -p ) greater than or equals 10.

Suppose the proportion of a population that has a certain characteristic is 0.35. The mean of the sampling distribution of ModifyingAbove p with caret from this population is mu Subscript ModifyingAbove p with caretequals0.35.

Step-by-step explanation:

Normal distribution is the shape data takes as a symmetrical bell shaped curve. Normal approximation can only be taken when np or np(1-p) greater than 10.
