Blizzard [7]3 years ago

Answer:

62.22%

Step-by-step explanation:

First, find how many total marbles there are:

12 + 11 + 17 + 5

= 45

Then, find how many marbles that are not blue:

12 + 11 + 5

= 28

Then, divide 28 by 45, and multiply by 100

(28/45) x 100

= 62.22% is the probability of not choosing a blue marble

What is the answer to the question
S_A_V [24]

The equation of the parallel line is y = –2x – 11.

Solution:

Given equation of the line is y = –2x – 5.

Slope of this line is (m_1) = –2

To write the equation parallel to this line and passes through (–4, –3).

<em>If two lines are parallel, then they have the same slope.</em>

\Rightarrow m_1=m_2

\Rightarrow m_2 =-2

<u>Point-slope formula:</u>

y-y_1=m(x-x_1)

Substitute the given values in the formula, we get

y-(-3)=-2(x-(-4))

y+3=-2(x+4)

y+3=-2x-8

Subtract 3 from both sides of the equation.

y+3-3=-2x-8-3

y=-2x-11

Hence the equation of the parallel line is y = –2x – 11.

11. A customer purchases a stroller and packs of diapers from a store. The table shows the total
bixtya [17]

Answer:

f(x) = 25x + 400

Step-by-step explanation:

Here, we want to find the relationship between the number of diaper packs and the total cost

From what we have in the options, we can see a linear relationship;

Since it is a linear relationship, it can be modeled using the equation;

y = mx + b

where m is the slope and b is the y-intercept

From what we have, we can identify the following parts;

where x represents number of diaper packs and f(x) or y represents total cost

The points identifiable are as follows;

(2,450) , (6,550) and (10,650)

The slope will be;

(550-450)/(6-2) = 100/4 = 25

So we have the equation partially as;

y = 25x + b

To get b, we can use any of the points

Let’s use (2,450)

Thus, we have

450 = 25(2) + b

b = 450 - 50

b = 450 - 50

b = 400

So the equation is;

y = 25x + 400

Thus;

f(x) = 25x + 400
