The radius of a circular rug is 4 feet. What is the area?​

Answer: The minimum score a person must have to qualify for the society = 147.4

Step-by-step explanation:

Let X be the test scores.

As per given,

X is normally distributed.

Mean [tex](\mu) = 110[/tex]

[tex]\sigma=5[/tex]

[tex]$$\begin{array}{l}\quad P(z>2)=0.07 \\\therefore \quad 1-P(z<2)=0.07 \\\therefore \quad P(2<2)=1-0.07 \\\therefore \quad P(2<2)=0.93 \\\qquad \begin{aligned}P(z<1.48) &=0.93[\text { using } z- \text { -table] } . \\z=1.48 \\\text { let } z &=\frac{x-\mu}{\sigma} \\x &=\mu+2 \sigma \\x &=140+(1.48)(5) \\x &=147.4\end{aligned}\end{array}$$[/tex]

The minimum score a person must have to qualify for the society = 147.4

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

Answer:

yes. In highschool the passing grade is

80-89 (B) thats pretty much good.

70-79 (C) average

65-69 (D) passing

BELOW 65 (F) FAILING

Although A - is the highest grade you can receive on an assignment, and it's between 90% and 100% ... D - this is still a passing grade, and it's between 59% and 69% F - that pretty much a failing grade.

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

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:

Its 6 <3

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

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:

[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]

Answer:

x = ± 5

Step-by-step explanation:

Given

x² - 25 = 0 ( add 25 to both sides )

x² = 25 ( take the square root of both sides )

x = ± [tex]\sqrt{25}[/tex] = ± 5

solutions are x = - 5, x = 5

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

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:

[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]

Answer:

the triangle is an isosceles triangle

The type of triangle STR is Isosceles triangle

Since the diagonal bisect each other, the triangle STR formed has two opposite sides equal to each other and the base angle of the triangle STR are congruent.

Therefore, triangle STR is an Isosceles triangle.

Isosceles triangle have two of it sides equal to each other.

Answer:

The appropriate answer is "0.437".

Step-by-step explanation:

Given:

P(rain) = 0.14

then,

P(no-rain) = 1-P(rain)

                 = 1-0.14

                 = 0.86

P(delay) = 0.16

P(rain and on time) = 0.79

then,

By using the conditional probability, we get

⇒ [tex]P(A|B)=\frac{P(A \cap B)}{P(B)}[/tex]

or,

⇒ [tex]P(no \ rain|delay) = \frac{P(no \ rain \cap delay)}{P(delay)}[/tex]

By substituting the values, we get

⇒                             [tex]=\frac{0.07}{0.16}[/tex]

⇒                             [tex]=0.437[/tex]
