Christina is making a necklace using beads. She has 20 red, 14 blue, 10 purple, 28 green, and 8 yellow beads. She randomly chooses a bead to start the necklace. What is the probability of Christina choosing a purple bead?

Answer:

2(8x+3y)*squared*

Answer:

Step-by-step explanation:

First answer A. Answer A is not even correct. Parallel are two or more lines that NEVER cross

Answer B is also not correct. Line segments are a line of specific length. These are two LINES. You can tell by the arrows on the edge of each line.

Both C and D can be correct. But the answer would be D. Here is why

Intersecting lines are two or more lines that cross. Yes these lines are crossing by perpendicular lines also cross. The difference is, intersecting lines can cross at any angle. Perpendicular lines have to cross at 90 degrees making 4 right corners.

Given:

[tex]x=-\dfrac{8}{9},\ y=-\dfrac{3}{5}[/tex]

To verify:

[tex]x+y=y+x[/tex]

Solution:

We need to verify,

[tex]x+y=y+x[/tex]

Taking left hand side, we get

[tex]LHS=x+y[/tex]

After substituting the values, we get

[tex]LHS=-\dfrac{8}{9}+\left(-\dfrac{3}{5}\right)[/tex]

[tex]LHS=-\dfrac{8}{9}-\dfrac{3}{5}[/tex]

[tex]LHS=\dfrac{-40-27}{45}[/tex]

[tex]LHS=\dfrac{-67}{45}[/tex]

Now,

Taking right hand side, we get

[tex]RHS=y+x[/tex]

After substituting the values, we get

[tex]RHS=-\dfrac{3}{5}+\left(-\dfrac{8}{9}\right)[/tex]

[tex]RHS=-\dfrac{3}{5}-\dfrac{8}{9}[/tex]

[tex]RHS=\dfrac{-27-40}{45}[/tex]

[tex]RHS=\dfrac{-67}{45}[/tex]

Clearly,

[tex]LHS=RHS[/tex]

Hence verified.

Answer:

Future Value= 8,927

Step-by-step explanation:

Giving the following information:

Present Value (PV)= 7,700

Growth rate (g)= 3%

Number of periods (n)= 5 years

To calculate the future value (FV) of the population after 5 years, we need to use the following formula:

FV= PV*(1 + g)^n

FV= 7,700*(1.03^5)

FV= 8,927

Given:

The function is:

[tex]y=-(2x-4)(x-2)[/tex]

To find:

The x-intercepts and zeros of the given function.

Solution:

We have,

[tex]y=-(2x-4)(x-2)[/tex]

For x-intercepts, [tex]y=0[/tex].

[tex]-(2x-4)(x-2)=0[/tex]

[tex](2x-4)(x-2)=0[/tex]

Using zero product property, we get

[tex](2x-4)=0[/tex] and [tex](x-2)=0[/tex]

[tex]2x=4[/tex] and [tex]x=2[/tex]

[tex]x=\dfrac{4}{2}[/tex] and [tex]x=2[/tex]

[tex]x=2[/tex] and [tex]x=2[/tex]

The given function has two equal zeroes or x-intercept, i.e., [tex]x=2[/tex].

Therefore, the zeroes are 2 and 2.

Note: All options are incorrect.

Answer:

B- y=[tex]\frac{1}{4}[/tex]x-2

Step-by-step explanation:

To look at the slope you can count over four and then up one and its at the next point.

Also, the place on the y-axis is at -2

So, b makes the most since :)

Answer:

Song =$1.50 Album =$12.99

Step-by-step explanation:

Lets assume Individual songs = x

albums=y

6x + y = 21.99-------- y= 21.99- 6x

4x + 3y= 44.97

Replace y in the second equation

4x+ 3(21.99-6x) = 44.97

4x +65.97- 18x = 44.97

14x= 21

x = 1.50

y= 21.99- (6*1.50)

= 12.99

Answer:

Probability(Not red) = 11 / 15

Step-by-step explanation:

Given:

Outcomes;

Red = 8

Blue = 7

Green = 9

Yellow = 6

Find:

Probability(Not red)

Computation:

Probability(Not red) = 1 - Probability(red)

Probability(Not red) = 1 - [Number of red/ Total]

Probability(Not red) = 1 - [8/(8+7+9+6)]

Probability(Not red) = 1 - [8/30]

Probability(Not red) = 1 - [4/15]

By taking LCM

Probability(Not red) = (15 - 4) / 15

Probability(Not red) = 11 / 15

Answer: $300 per month (assumed)

Step-by-step explanation:

As figures are lacking in this question, I will use assumed figures and you can use it as a reference.

Assume Penelope had been tutoring for 60 hours a month and her hourly rate was $10 originally.

If she reduces this time to half, the amount of hours she begins to tutor is:

= 60 hours / 2

= 30 hours

At a rate of $10 an hour, her monthly income becomes:

= 10 * 30

= $300 per month

Answer:

y = 3x + 1

Step-by-step explanation:

the slope of the line of the given equation can bé find in this way: -a/b, where a is the number that multiplies x and b is the number that multiplies y

m = -3/-1 = 3

two parallel lines have the same slope, so also the line that we are a searching has m=3

now we can use this formula

y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the given point

y-(-2) = 3 (x-(-1)

y+2 = 3x + 3

y = 3x + 3-2

y = 3x + 1

Answer:
