Answer:

0.722

Step-by-step explanation:

First of all add up the sections 1 to 8 to make sure they add to 360

They do actually.

Total    360

This is an area question. Every time you spin the spinner, it must come to an area labeled 1 to 8.

You could do this by setting up a ratio of each section and subtract the section for 3 and 7.  That's the long way.

The shorter way is to add up the degrees for 3 and 7 and subtract them from the total (360)

Area 3 + area 7 = 30o + 70o = 100 degrees.

So the probability of landing in 3 or 7 is 100 / 360 = 0.278 (rounded)

The probability of Not landing on 3 or 7 is 1 - 0.278 = 0.722

Answer:

82/55

Step-by-step explanation:

11/12 * 12/121 - -6/5 * 70/60 = 1/11 + 14/10 = 1/11 + 7/5 = 5/55 + 77/55 = 82/55

The required solution of the given expression is 82/55.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve, For example, simplifying an algebraic expression might involve combining like terms, factoring, or using the distributive property

The given expression is,

= 11/12*12/121- -6/5*70/60

Simplify the above expression,
= 11/121+ 70/50

= 1/11 + 7/5

The common denominator between the two fractions is 55, so

= 5 + 77 / 55
= 82 / 55

Thus, the required solution of the given expression is 82/55.

Answer:

5x+4y = 24

Step-by-step explanation:

We know the y intercept = 6

We can find the slope

(0,6) and (4,1)

m = ( y2-y1)/(x2-x1) = ( 1-6)/(4-0) = -5/4

The slope intercept form is y = mx+b where m is the slope and b is the y intercept

y = -5/4x+6

Multiply each side by 4

4y = -5x+24

Add 5x to each side

5x+4y = 24

The standard form of a line is

Ax +By = C  where A,B C are integers and A > 0

gradient or slope=y2 -y1

x2 - x1

so for A, p is x1 and 3 is y1..

For B, 6 is x2 and p is y2

2= p - 3

6 - p

2 ( 6 - p) = p - 3

12 - 2p = p - 3

-2p + p = -3 - 12

-p = - 15

p = 15

Answer:

216

Step-by-step explanation:

Correct on Edge

The solution is: 216,  is missing number in the table of values below.

An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.

Given :

x = 0 ,1 ,2 ,3 , 4

y = 1 ,6 ,36 ,? , 1296

As we can see that values of y :

y = 6^0 = 1

y = 6^1 = 6

y = 6^2 = 36

y = 6^3 = 1296

so y =216 , is the solution

so, we get, the values of y is exponent of 6 as the values of x, respectively.

The equation can be given for solving the question is y = 6^x

By putting given values of x we are getting values of y .

So for x =3 we are getting y = 216

Hence, 216,  is missing number in the table of values below.

Answer:

30.8 degrees

Step-by-step explanation:

cosx = [tex]\frac{8.5}{9.9}[/tex]

Answer:

[tex]P(0.0014 < x < 0.0026) = 0.86639[/tex]

Step-by-step explanation:

Given

[tex]\mu = 0.002[/tex]

[tex]\sigma = 0.0004[/tex]

Required

[tex]P(0.0014 < x < 0.0026)[/tex]

First, calculate the z score

[tex]z = \frac{x - \mu}{\sigma}[/tex]

For x = 0.0014

[tex]z = \frac{0.0014 - 0.002}{0.0004}[/tex]

[tex]z = \frac{-0.0006}{0.0004}[/tex]

[tex]z = -1.5[/tex]

For x = 0.0026

[tex]z = \frac{0.0026 - 0.002}{0.0004}[/tex]

[tex]z = \frac{0.0006}{0.0004}[/tex]

[tex]z = 1.5[/tex]

So, we have:

[tex]P(0.0014 < x < 0.0026) = P(-1.5<z<1.5)[/tex]

From z probability table, we have:

[tex]P(-1.5<z<1.5) = 0.86639[/tex]

Hence:

[tex]P(0.0014 < x < 0.0026) = 0.86639[/tex]

Step-by-step explanation:

When testing a number of triples to see if they are Pythagorean triples, it can be convenient to let a spreadsheet do the math. The attachment shows us the triple at lower left (30, 72, 78) is a Pythagorean triple. That is, the sum of the squares of the smaller two numbers is the square of the larger, so they can form a right triangle.

Answer:

[tex]P(-3\% < x < 3\%) = 0.901[/tex]

Step-by-step explanation:

Given

[tex]p = 21\%[/tex]

[tex]n = 498[/tex]

Required

[tex]P(-3\% < x < 3\%)[/tex]

First, we calculate the z score

[tex]z = \sqrt{p * (1 - p)/n}[/tex]

[tex]z = \sqrt{21\% * (1 - 21\%)/498}[/tex]

[tex]z = \sqrt{21\% * (79\%)/498}[/tex]

[tex]z = \sqrt{0.1659/498}[/tex]

[tex]z = \sqrt{0.000333}[/tex]

[tex]z = 0.0182[/tex]

So:

[tex]P(-3\% < x < 3\%) = P(-3\%/0.0182 < z <3\%/0.0182)[/tex]

[tex]P(-3\% < x < 3\%) = P(1.648 < z <1.648)[/tex]

From z probability, we have:

[tex]P(-3\% < x < 3\%) = 0.901[/tex]

Three-week moving average forecast

[tex]\begin{array}{ccc}{Week} & {Time\ Series\ Value} & {Forecast} & {1} & {18} & { } & 2 & {13} & { } & {3} & {16} & { } & {4} & {11} & {15.67 } & 5 & {17} & {13.33 } & {6} & {14} & {14.67 } \ \end{array}[/tex]

[tex]MSE = 11.90[/tex]

Step-by-step explanation:

Given

[tex]\begin{array}{ccccccc}{Month} & {1} & {2} & {3} & {4} & {5}& {6} & {Value} & {18} & {13} & {16} & {11} & {17} & {14} \ \end{array}[/tex]

Solving (a): Three-week moving average forecast

This is calculated as:

[tex]F_{t+1} = \frac{\sum recent\ k\ data}{k}[/tex]

Since it is three-week, we start from t = 3

For t = 3; we consider months 1, 2 and 3

[tex]F_{3+1} = \frac{18 + 13 + 16}{3}[/tex]

[tex]F_{4} = \frac{47}{3}=15.67[/tex]

For t = 4; we consider months 2, 3 and 4

[tex]F_{4+1} = \frac{13 + 16+11}{3}[/tex]

[tex]F_{5} = \frac{40}{3}=13.33[/tex]

For t = 5; we consider months 3, 4 and 5

[tex]F_{5+1} = \frac{16+11+17}{3}[/tex]

[tex]F_{6} = \frac{44}{3}=14.67[/tex]

So, the forecast are:

[tex]F_{4} =15.67[/tex]

[tex]F_{5} = 13.33[/tex]

[tex]F_{6} = 14.67[/tex]

[tex]\begin{array}{ccc}{Week} & {Time\ Series\ Value} & {Forecast} & {1} & {18} & { } & 2 & {13} & { } & {3} & {16} & { } & {4} & {11} & {15.67 } & 5 & {17} & {13.33 } & {6} & {14} & {14.67 } \ \end{array}[/tex]

Solving (b): MSE

To do this, we simply calculate the square of the forecast error

The forecast error (E) is:

[tex]E = Time\ Series\ Value - Forecast[/tex]

So, we have:

Forecast error                                                     The square

[tex]E_4 = 11 - 15.67 = -4.67[/tex]                                       [tex]E_4^2 =21.81[/tex]

[tex]E_5 = 17 - 13.33 = 3.67[/tex]                                          [tex]E_5^2 = 13.45[/tex]

[tex]E_6 = 14 - 14.67 = -0.67[/tex]                                       [tex]E_6^2 = 0.45[/tex]

[tex]MSE = \frac{E_4^2 + E_5^2 + E_6^2}{3}[/tex]

[tex]MSE = \frac{21.81 + 13.45 + 0.45}{3}[/tex]

[tex]MSE = \frac{35.71}{3}[/tex]

[tex]MSE = 11.90[/tex]

Answer:

V=27/2 units^3

Step-by-step explanation:

The volume of a rectangular prism is l*w*h

V=l*w*h

We are already given the w*h, which is 27/5 units^2.

Now all we need to do is multiply that with the length, 5/2 units. So,

V=(5/2 units) * (27/5 units^2)

V=27/2 units^3
