Answer:

126

Step-by-step explanation:

n! / (r! (n-r)!)

In this case n = 9 and r = 4

9!/ (4! * (9-4)!)

9!/ (4! * 5!)

= 126

9! = 9x8x7x6x5x4x3x2x1

explanation:

1. What type of pattern exists in the data

the data has the horizontal pattern

2. for moving average

mse = 11.11/9

= 1.23

for exponential smoothing forecast

mse = 39.11/11

= 3.56

3. we are to calculate the forecast for next month

83+84+83/3

= 83.33

Answer

Ammmm did u just gave free points

Part 1

[tex]x = g(y), \ c \le y \le d\\\\\\x = 3+4y^2, \ 1 \le y \le 2\\\\\\\frac{dx}{dy} = 8y, \ 1 \le y \le 2\\\\\\\displaystyle A = 2\pi \int_{c}^{d}y\sqrt{1+[g'(y)]^2}dy\\\\\\\displaystyle A = 2\pi \int_{c}^{d}y\sqrt{1+\left[\frac{dx}{dy}\right]^2}dy\\\\\\\displaystyle A = 2\pi \int_{1}^{2}y\sqrt{1+(8y)^2}dy\\\\\\\displaystyle A = 2\pi \int_{1}^{2}y\sqrt{1+64y^2}dy\\\\\\\displaystyle A = 2\pi \int_{1}^{2}\sqrt{1+64y^2}*ydy\\\\\\\displaystyle A = 2\pi \int_{65}^{257}\sqrt{u}*\frac{du}{128}\\\\\\[/tex]

In the last two steps I let u = 1+64y^2, so du/dy = 128y which leads to ydy = du/128.

Note the change in the limits of integration. If y = 1, then u = 1+64y^2 = 65. If y = 2, then 1+64y^2 = 257

----------------------------

Part 2

[tex]\displaystyle A = 2\pi \int_{65}^{257}\sqrt{u}*\frac{du}{128}\\\\\\\displaystyle A = 2\pi*\frac{1}{128}\int_{65}^{257}u^{1/2}*du\\\\\\\displaystyle A = \frac{\pi}{64}\int_{65}^{257}u^{1/2}*du\\\\\\\displaystyle A = \frac{\pi}{64}\left(\frac{2}{3}u^{3/2}+C\right)\Bigg]_{65}^{257}\\\\\\\displaystyle A = \frac{\pi}{64}\left(\left(\frac{2}{3}(257)^{3/2}+C\right)-\left(\frac{2}{3}(65)^{3/2}+C\right)\right)\\\\\\\displaystyle A = \frac{\pi}{64}*\frac{2}{3}\left((257)^{3/2}-(65)^{3/2}\right)\\\\\\[/tex]

----------------------------

Part 3

[tex]\displaystyle A = \frac{\pi}{96}\left(\sqrt{257^3}-\sqrt{65^3}\right)\\\\\\\displaystyle A = \frac{\pi}{96}\left(\sqrt{257^2*257}-\sqrt{65^2*65}\right)\\\\\\\displaystyle A = \frac{\pi}{96}\left(\sqrt{257^2}*\sqrt{257}-\sqrt{65^2}*\sqrt{65}\right)\\\\\\\displaystyle A = \frac{\pi}{96}\left(257\sqrt{257}-65\sqrt{65}\right)\\\\\\[/tex]

[tex]\displaystyle A = \frac{\pi}{96}*257\sqrt{257}-\frac{\pi}{96}*65\sqrt{65}\\\\\\\displaystyle A = \frac{257\pi\sqrt{257}}{96}-\frac{65\pi\sqrt{65}}{96}\\\\\\\displaystyle A = \frac{-65\sqrt{65}\pi}{96}+\frac{257\sqrt{257}\pi}{96}\\\\\\[/tex]

Answer:

Step-by-step explanation:Basic Math. Simplify (6y-3)(6y+3). (6y−3)(6y+3) ( 6 y - 3 ) ( 6 y + 3 ). Expand (6y−3)(6y+3) ( 6 y - 3 ) ( 6 y + 3 ) using the FOIL Method

Answer:

78°

Step-by-step explanation:

Since, angles A and B are complementary.

[tex]\therefore m\angle A + m\angle B = 90\degree \\

\therefore (3x+9)\degree + (x - 11)\degree = 90\degree \\

\therefore (3x +x +9-11)\degree = 90\degree \\

\therefore (4x - 2)\degree = 90\degree \\

\therefore 4x - 2 = 90\\

4x = 90+2\\

4x = 92\\ \\ x = \frac{92}{4} \\ \\ x = 23 \\ \\ \because m\angle A = (3x+9)\degree \\ \therefore \: m\angle A = (3 \times 23+9)\degree \\ \therefore \: m\angle A = (69+9)\degree \\ \huge \red{ \boxed{ \therefore \: m\angle A = 78\degree }}[/tex]

3/4 converted into 8ths is 6/8. When you add up 6/8 + 7/8, you end up with the answer of 13/8

Hope this was helpful! (brainliest please)

Make them have common denominators:

3/4 = 6/8

so...

6/8 + 7/8 = 13/8

Answer:

Diverges

Step-by-step explanation:

The order of the numerator (2) is greater than the order of the denominator (1).  So the sequence will diverge as n approaches infinity.

Answer:

The predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes

Step-by-step explanation:

Regression Output :

Predictor                            Coefficient

Constant                             3.0979

Square root of items          2.7633

R.sq.- 96.7%

So, with this data the regression equation is,

[tex]\hat{y}=3.0979+2.7633x[/tex]

Now we are supposed to find the predicted time, in minutes, that it took to gather the items if the order has 22 items

Substitute x =22 in equation

[tex]\hat{y}=3.0979+2.7633(22)[/tex]

[tex]\hat{y}=63.8905[/tex]

Hence the predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes

Answer:

this doesnt even relate to the answer. blasphomy.

Step-by-step explanation:

Answer:

x = 10  

Step-by-step explanation:

recall that for a square with side length "L", the area of the square can be expressed as

Area = L x L

or

Area = L²

in this case we are given that Area, A = 32x

and that Side Length, L = 8√5

If we substitute these into the equation, we will get:

Area = L²

32x = (8√5)²   (using the properticals of exponents, we can re-write the right side)

32x = (8)² · (√5)²  

32x = 64 · 5

32x = 320   (divide both sides by 32)

x = 320 / 32

x = 10  

Answer:

length 36, width, 9.

Step-by-step explanation:

you are trying to find "X" and it's 4 times the size of y, the whole thing is equal to 90. it would look like this

y=4x

y(4x) + x = 90

5x=90

90/5= 18

the rest is the "y" value, 72.

divide both by 2 because rectangles have 4 sides, and you get the answer above.

Answer:

m<8 = 26°

Step-by-step explanation:

Given:

m<3 = 124°

Required:

m<8

SOLUTION:

Find m<4.

m<4 + m<3 = 180° (linear pair)

m<4 + 124° = 180°

m<4 + 124° - 124° = 180 - 124°

m<4 = 26°

Find m<8:

m<8 = m<4 (corresponding angles)

m<8 = 26° (substitution)

The variable that was defined and the corresponding inequality to depict the constraints is; r < 140 beats per minute.

We are to define a variable and write an inequality for the given question.

Now, since the variable here is the heart rate, then let us define the varibale with the term r.

Thus, the inequality that represens the given question is written as;

r < 140 beats per minute.

Answer:

Well, lets break this down.

If you try to add 26 + 26 it would be 52, which is above 48.

So, we have to find how many books he can read in one month.

All we have to do, is divide!

14 = dividend

26 = divisor

Step 1:

Start by setting it up with the divisor 26 on the left side and the dividend 14 on the right side like this:

26⟌14 Then do the rest, ill wait.

once you have a answer, that is how much he reads a month.

now multiply by 48.

Answer:

0.125

Step-by-step explanation:

to get the reciprocal of a number we divide the number by 1

in this case it would be 1 divide by 8
