Answer:

77

Step-by-step explanation:

13 x 77 = 1001 which is 1 more than enough, so the answer would be 77.

Answer:

77 boxes

Step-by-step explanation:

Hello there! Let's solve this problem together:

First, we will review our numbers.

13 girls have to sell 1,000 boxes.

Now, we will do the math.

We will solve this problem by dividing.

We will keep multiply by one until we reach 1000 or more.

They have to each sell at least 77 boxes.

Best of Luck!

Answer:

y =1/3x+20

Step-by-step explanation:

He starts 20 minutes late so we need to add 20 minutes to the time

He travels 3 times faster so he takes 1/3 of the normal time x

y =1/3x+20

Answer:

A) y = 1/3x + 20

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:

6

Step-by-step explanation:

Graphically, this is a very easy question to cheat through.  I'll show the easiest way to solve.

First, add the four squares that make up the square in the center of the quadrilateral.  Now, notice that the two triangles left on the ends are exactly the same size.  So if you put them together, the cover up two more squares.  Which gives you 2 + 4 =6.

Or the mathematical way which is to find the area of the square as 2 * 2 = 4

and the area of one triangle as 1/2 * 2 * 1 = 1 ad the other triangle is the same.  So add all three 4 + 1 + 1 = 6

Answer:

4 4/27 sq inches

Step-by-step explanation:

the area is 2⅔ × 1 5/9 = 8/3 × 14/9

= 112/27 = 4 4/27

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:

c

Step-by-step explanation:

0 is at 3 so its +3

the difference between y's is -2 and between x's is 1 so -2/1 is -2 as you slope

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:

30.8 degrees

Step-by-step explanation:

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

x= [tex]cos^{-1}[/tex][tex]\frac{8.5}{9.9}[/tex]

= 30.8 degrees (nearest tenth of a degree)

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:

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:

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

FREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

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]

Answer:

4z+12

hope this helps

have a good day :)

Step-by-step explanation:

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:

[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:

[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]
