Describe the y-intercept and end behavior of the following graph

Answer:

B

Step-by-step explanation:

Marcus can expect to have red chip 20 times.

Probability denotes the possibility of the outcome of any random event. The meaning of this term is to check the extent to which any event is likely to happen.

Given that, Marcus has a bag of 10 red chips, 15 blue chips, and 5 black chips.

He did an experiment 60 times and we need to find that how many times would he expect to pick a red chip,

So,

Here the favorable outcomes = red chips (10)

Total outcomes = all the chips = 15+5+10 = 20

So, the probability of finding a red chips for the 60 times = 10/20 x 60

= 30

Hence, Marcus can expect to have red chip 20 times.

Answer:

C.

Step-by-step explanation:

Before graphing this equation we first need to isolate y on one side like so...

y + 2 = 3(x+1)   ... distribute the 3 to both values inside the parenthesis

y + 2 = 3x + 3   ... subtract 2 on both sides

y = 3x + 1

Now that we have the y variable isolated we see that the slope of the function is 3, meaning that for every 1 unit right the line needs to move 3 units up. We also have the value where the line needs to cross the y-axis and that is 1. Using this information we see that the correct graph is C.

Answer:

y = 0, -2

Step-by-step explanation:

Factor out the common term 3y.

[tex]3y( {y}^{2} + 4y + 4) = 0[/tex]

Rewrite y² + 4y + 4 in the form of a² + 2ab + b², where a = y and b = 2.

[tex]3y( {y}^{2} + 2(y)(2) + {2}^{2} ) = 0[/tex]

Use square sum: (a + b)² = a² + 2ab + b².

[tex]3y(y + 2) ^{2} = 0[/tex]

solve for y.

y = 0, -2.

therefor, the answer for this equation is 0, - 2.

Answer:

$258.75

Step-by-step explanation:

225 * 0.15

Let last weeks pay = x

This week she earned 15% more so she earned 100% + 15% more for 115% total.

Setup an equation:

115% times x = $225

115% as a decimal = 1.15

So the equation is:

1.15x = 225

Solve for x by dividing both sides by 1.15:

X = 225/1.15

X = 195.65

Last week she earned $195.65

Answer:

y diles que yo me se tu pose favorita, que te hablo mal y que eso te U-U

Step-by-step explanation:

Answer:

We know that:

Sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)

Then if we use this property in our expression:

sin(a-30)-sin(a+30)

We get:

sin(a)*cos(-30°) + sin(-30°)*cos(a) - sin(a)*cos(30°) - sin(30°)*cos(a)

Now remember that:

sin(-x) = -sin(x)

and

cos(-x) = cos(x)

Then we can rewrite our expression as:

sin(a)*cos(30°) - sin(30°)*cos(a) - sin(a)*cos(30°) - sin(30°)*cos(a)

= -2*sin(30°)*cos(a)

and sin(30°) = 0.5

Then:

-2*sin(30°)*cos(a) = -2*0.5*cos(a) = -cos(a)

So we get:

sin(a-30)-sin(a+30)= - cos(a)

Answer:

120

Step-by-step explanation:

LCM of (2^3×3×5) and (3×5) is​

The LCM of the expression will be the product of all the factors that are in both expressions

(2^3×3×5) = 2 * 2 * 2 * 3 * 5

(3 * 5) = 3 * 5

since 3 * 5 is common to both factors, we will not have to repeat it twice to get our LCM again. Hence the LCM is expressed as;

LCM = 2 * 2 * 2 * 3 * 5

LCM  = 8 * 3 *5

LCM = 24 * 5

LCM = 120

Hence the required LCM is 120

Answer:

  e(w) = -40w^2 +400w +20

Step-by-step explanation:

A graphing calculator or spreadsheet can do the quadratic regression and help you find the formula. Here earnings (e) as a function of weeks (w) can be expressed by ...

  e(w) = -40w^2 +400w +20

__

Further development

There are a couple of other ways you can go at this. One is to write equations for a, b, c using the standard form quadratic.

  aw^2 +bw +c = e

  a +b +c = 380 . . . . . . for week 1

  4a +2b +c = 660 . . . for week 2

  9a +3b +c = 860 . . . for week 3

The solution of this system of equations will give the coefficients of the quadratic. Your graphing calculator or any of several web sites can solve these equations for you.

__

Consider the differences between quadratic values for w = 1, 2, 3.

  e2 -e1 = (4a +2b +c) -(a +b +c) = 3a +b

  e3 -e2 = (9a +3b +c) -(4a +2b +c) = 5a +b

Then the second differences are ...

  (e3 -e2) -(e2 -e1) = (5a +b) -(3a +b) = 2a

In the given set of numbers, the first differences are ...

  660 -380 = 280 . . . . . . . call this d1

  860 -660 = 200

And the second difference is ...

  200 -280 = -80 . . . . . . . call this d2

From the above, we know that 2a = -80  ⇒  a = -40

and 3a +b = 280 = 3(-40) +b  ⇒  b = 400

Finally, a+b+c = 380 = -40 +400 +c  ⇒  c = 20

Then the generic solution is ...

  a = d2/2

  b = d1 -3a

  c = e1 -a -b . . . . . where e1 is the first-week's earnings

A: save $250 per month for the next 3 years

Step-by-step explanation:

Melinda has three more years in high school as stated in the question.

One year private university tuition = $22,500

Support from family = $13,500

Amount that Melinda has to pay = $22,500 - $13,500 = $9000

Number of months in three years = 3 * 12 = 36 months

If she must save $9000 in 36 months

Then $x  must be saved in 1 month

x = $9000/36

x = $250

The answer is A the y=2.25

The equation of the exponential regression that fits these data,

y = 2.25 [tex](1.75)^x[/tex]

It is a model that explains processes that increase at twice the rate. It is employed in circumstances where growth starts slowly but quickly accelerates without bounds, or decay starts quickly but slows down to zero.

The formula for expressing Exponential Regression is

y = a[tex]b^x[/tex]

We have given that,

The table below represents The closing prices of stock at TUV for the last five days

Days      Value

1           3.938

2          6.891

3          12.059

4          21.103

5          36.929

First we have to find r as

r= 6.891/ 3.938

r = 1.749

As, the standard form of Exponential function

y = a[tex]b^x[/tex]

So, y = 2.25 [tex](1.75)^x[/tex]

Step-by-step explanation:

Remark

I'm hesitant to get an exact answer. You could do that with the cos law for distance. To get an approximate answer you could use the Pythagorean Theorem.

I'll try the cos law first.

Formula

c^2 = a^2 + b^2 - 2abcos(C)

Givens

c = 24

a = 18

b = ?

Solution

24^2 = 18^2 + b^2 - 2*18*b*cos(94)

576 = 324 + b^2 - 36*b*(-0.0698)

0 = 324 - 576 + b^2 + 2.511b

0 = b^2 + 2.511 - 252

Using the quadratic formula, the roots are

b1 = 14.66

b2 = - 17.11

The second one has no meaning in the real world.

Answer

the distance is 14.66 miles from Chaplin to Asherville

Note: using the Pythagorean theorem gives 15.87 which I would count as a good approximation.

Answer:

14.7

Step-by-step explanation:

got 100% on plato

Answer:

First, assume that we have 14 seats in a row.

Let's count the total number of combinations assuming that the 14 kids are differentiable.

In the first seat, we can sit only one child, the number of options is (14)

In the second seat, we can sit another child, in this case, the number of options is 13, because one child is already seated.

For the third seat, we will have 12 options.

for the fourth seat we will have 11 options, and so on.

The total number of permutations is equal to the product between the numbers of options for each case.

Then the total number of permutations is:

P = 14*13*12*11*...*3*2*1 = 14!

Now, we need to discount the permutations of the two sets of identical triplets:

a triplet has 3 elements, then the permutations of each set of triplets is:

p = 3*2*1 = 3!

Then if we discount two sets of triplets, we need to divide by:

d = 2*(3!)

We also have 3 sets of twins, the permutations for each set of twins is:

p = 2*1 = 2!

Then if we discount the 3 sets of twins, we need to by:

q = 3*(2!)

Then the total number of different combinations will be:

[tex]P = \frac{14!}{2*(3!)*3*(2!)} = 1,210,809,600[/tex]
