A teacher keeps track of the number of students that participate at least three times in an optional study session each year. He models the attendance over the last nine years with this function. n(t) = 3.53t^2 - 33.04t + 117.56 Which graph would most likely be associated with the given model?

Answer:

The LCM of 10, 5 and 3 is 30.

Answer:

Step-by-step explanation:

Since we don't know x, let's come up with our own.

Lets chose 6 for x.

Now, let's plug in 6: y = 2 * 6 - 7

Multiply: y = 12 - 7

Subtract: y = 5

So our first point is  (6, 5)

Now lets choose a second x: 5

Plug it in: y = 2 * 5 - 7

Multiply: y = 10 - 7

Subtract: y = 3

So our second point is (5, 3)

Find both of these points and your answer should look like the attached image.

I hope this helped, please mark Brainliest, thank you !!

Answer:

3 = 2(5) + b

Step-by-step explanation:

Equation for a slope is y=mx+b.

Y = Y-value on the graph

M = The slope

X = X-value on the graph

B = Y-intercept

If the coordinates are ( x, y )

Then that must mean that x = 5 and y = 3 because the numbers would replace the variables in the same order

The B-value is unknown for now but you are able to find it by solving this algebraically.

3=2(5) + b

3 = 10 + b

-10 = -10 + b

-7 = b    

Because the 10 and the -10 would cancel each other. Leaving you with only -10 on the other side.

I hope that this helps.

Answer:

[tex]f(x+h)=x^2+2xh+h^2+2x+2h[/tex]

Option D is correct option.

Step-by-step explanation:

We are given: [tex]f(x)=x^2+2x[/tex]

We need to find f(x+h)

For finding f(x+h) we need to replace x by x+h

[tex]f(x+h)=(x+h)^2+2(x+h)\\We \ know \ (a+b)^2=a^2+2ab+b^2\\f(x+h)=x^2+2xh+h^2+2x+2h[/tex]

Finding f(x+h) we get:

[tex]f(x+h)=x^2+2xh+h^2+2x+2h[/tex]

Option D is correct option.

Answer:

The answer is "Coordinates of point P= (2,5)"

Step-by-step explanation:

We are familiar with the internal division of AB by point P, i.e. 3:2, [tex]\frac{AP}{PB}= \frac{3}{2}[/tex]

Therefore, we use the internal division formula.

Points:

[tex]\to (-4,8) \ and \ (6,3)\\\\ x_1 = -4\\y_1 = 8\\x_2= 6\\y_2 =3 \\[/tex]

Formula:

[tex]\to x = \frac{(mx_2 + nx_1)}{(m + n)}\\\to y = \frac{(my_2 + ny_1)}{(m + n)}\\\\where,\\\\\to m = 3 \\ \to n = 2[/tex]

Replacing the x coordinate representations of A and B with x, we have

[tex]x = \frac{(3 \times 6 + 2 \times (-4))}{(3 + 2)}\\\\[/tex]

   [tex]= \frac{(18 - 8)}{5}\\\\ = \frac{10}{5}\\\\ = 2[/tex]

Replacing the, y coordinate representations of A and B with y, we have

[tex]y = \frac{(3 \times 3 + 2 \times 8)}{(3 + 2)}\\\\[/tex]

  [tex]= \frac{( 9 +16)}{(5)}\\\\= \frac{25}{5}\\\\=5[/tex]

The coordinates of point P= (2,5).

Answer:

Equation: x + 2 = 7/8x - 15

Solution: x = -136

Explanation:

x + 2 = 7/8x - 15

2 + 15 = 7/8x - x

17 = 7/8x - 8/8x

17 = -1/8x

17 × -8 = x

-136 = x

Answer:

500

Step-by-step explanation:

First of, multiply all of the number by 10 to remove the decimal place ( this will make it less confusing)

So 102.3 x 10= 1023

4.7 x 10 = 47

You will have to round each of the numbers to 1 significant figure (sf) :

1023 round to 1 sf will be 1000

47 rounded to 1 sf will be 50

Then multiply these numbers:

1000 x 50 = 50000

Finally divide by 100 to get back the decimal places

(You divide by 100 because you multiplied by 10 twice, 10 x 10= 100)

You get 500

Answer:

x = 9

Step-by-step explanation:

84 + (7x + 5) + (180 - (17x-1)) = 180

84 + 7x + 5 + (181 - 17x) = 180

270 + (-10x) = 180

90 = 10x

x = 9

Answer: B) The result is a prime number

==================================================

Explanation:

Replace x with 5. Then use PEMDAS to simplify.

7x+6

7*5+6

35+6

41

The expression 7x+6 is equal to 41 when x = 5.

The value 41 is prime because its factors are only 1 and 41.

Answer:

First, these angles are alternate interior angles.

[tex] 10x - 5 = 9x + 1 [/tex]

[tex] x = 6 [/tex]

Step-by-step explanation:

(10x - 5)° and (9x + 1)° are alternate interior angles. Thus, they are congruent to each other.

Thus, to find x, we will set each angle equal to the other.

[tex] 10x - 5 = 9x + 1 [/tex]

Solve for x. Collect like terms

[tex] 10x - 9x = 5 + 1 [/tex]

[tex] x = 6 [/tex]

Answer:

Y = 3/5x + 2

Step-by-step explanation:

Answer:

[tex]y=\frac{3}{5} x+2[/tex]

Answer:

The probability that X is greater than Y is 0.5754.

Step-by-step explanation:

It is provided that,

[tex]X\sim N(184.09, 39.37)\\\\Y\sim N(171.93, 50.88)[/tex]

It is also provided that X and Y are independent.

We need to compute the value of:

P (X > Y) = P (X - Y > 0)

Compute the mean and standard deviation of (X - Y) as follows:

[tex]E(X-Y)=E(X)-E(Y)=184.09-171.93=12.16\\\\SD(X-Y)=\sqrt{V(X-Y)}=\sqrt{V(X)+V(Y)}=\sqrt{39.37^{2}+50.88^{2}}=64.33[/tex]

Compute the the value of P (X > Y) as follows:

[tex]P(X>Y)=P(X-Y>0)\\\\=P(\frac{(X-Y)-E(X-Y)}{SD(X-Y)}>\frac{0-12.16}{64.33})\\\\=P(Z>-0.19)\\\\=P(Z<0.19)\\\\=0.57535\\\\\approx 0.5754[/tex]

Thus, the probability that X is greater than Y is 0.5754.

Answer:

Step-by-step explanation:

Step one:

given

number of shirts= 500

cost of all the shirts= $12000

unit cost of shirt= 12000/500

                          =$24

the selling price = $30

the profit per shirt= selling price-cost price

30-24=$6

Required

% mark up

% mark up=( profit/cost price)*100

% mark up=( 6/24)*100

% mark up=0.25*100

% mark up=25%

Hence the % mark up is 25%
