PLS ASAP I HAVE BEEN UP LATE I NEED HELP!!

Answer:

c. Fewer than 6

Step-by-step explanation:

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

In the binomial distribution, an outcome is considered unusual if it is more than 2.5 standard deviations below the mean.

Seventy-nine percent of products come off the line ready to ship to distributors.

This means that [tex]p = 0.79[/tex]

Your quality control department selects 12 products randomly from the line each hour.

This means that [tex]n = 12[/tex]

Mean:

[tex]E(X) = np = 12*0.79 = 9.48[/tex]

Standard deviation:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{12*0.79*0.21} = 1.41[/tex]

Unusual:

[tex]9.48 - 2.5*1.41 = 5.96[/tex]

So fewer than 6 is considered unusual.

Answer:

The answer is B. 9x + 22

Step-by-step explanation:

17.50x + 25

- 8.5x + 3

= 9x + 22

Answer:

$760

Step-by-step explanation:

Given data

weekly = $325

commission= 7.5%

if she sold $5,800 worth of merchandise

Her earnings will be

Week earning= base salary+ 7.5% of sales

Week earning= 325+ 7.5/100*5800

Week earning= 325+ 0.075*5800

Week earning= 325+ 435

Week earning= $760

Answer:

The answer to this question is B

Answer:

the answer for this question is 110°

Step-by-step explanation:

you have to add the angles first in this case 25 and 45

and then subtract the sum from 180.

so.... 25+45=70

        180-70=110

hope its was helpful :)  

Answer:

Step-by-step explanation:

The sum of the exterior angles of any polygon is 360 degrees and the QRST is not an exception.

Answer:

its 45

reason is 216-81 = 135 divide by 135/3=45

Answer:

2 (12a-3)

Step-by-step explanation:

do distributive property

2 x 12a = 24a

2 x -3 = -6

Answer:

2(12-3)

Step-by-step explanation:

2 x 12 =24 2 x -3=-6

Answer:

The factors: x + 2 and 3

The product: 3x + 6

Answer:

12.5 kg

Step-by-step explanation:

50 divided by 4 = 12.5

Answer: 37.5kg

Step-by-step explanation:

When you hear "of", it indicates multiplication. When you multiply by 1/4, you can also divide by 4 to get the same answer. 50/4 = 12.5kg sold

But that isnt our net sugar because thats how much he sold. Subtract that from what he has currently, and youll get the sugar he has after selling the 1/4th.

50 - 12.5 = 37.5kg

Answer:

Undefined

Step-by-step explanation:

Add 5 to both sides to get the equation x=5. X=5 is a vertical line. The slope, or change in y / change in x would be undefined since the change in x is always zero. Anything divided by zero is undefined.

Answer:

Step-by-step explanation:

Not completly sure what your looking for but it X would be any number lower then 12 (11,10,9,8,7,6,5,4,3.2,1)

Answer:

1-11

Step-by-step explanation:

its less than 12!

Answer:

The distance from point P, P(-2,4) to the given line y= 2x-2 is 1.56

Step-by-step explanation:

We need to find the distance from point P to the given line

P(-2,4) , y= 2x-2

The formula used is: [tex]Distance=\frac{|Ax_1+By_1+C|}{\sqrt{A^2+B^2} }[/tex]

Where A, B and C are points of line i.e Ax+By+C=0

and x_1 and y_1 are points of P

So, y=2x-2 in Ax+By+C=0 is:

2x-y-2=0

A=2,

B=-1

C=1

Point given is P(-2,4)

x_1=-2

y_1=4

Putting values and finding distance

[tex]Distance=\frac{|Ax_1+By_1+C|}{\sqrt{A^2+B^2} }\\Distance=\frac{|2(-2)+-1(4)+1|}{\sqrt{(-2)^2+(4)^2} }\\Distance=\frac{|-4-4+1|}{\sqrt{4+16} }\\Distance=\frac{|-7|}{\sqrt{20}}\\Distance=\frac{7}{\sqrt{20} }\\Distance=\frac{7}{4.5}\\Distance=1.56[/tex]

So,  the distance from point P, P(-2,4) to the given line y= 2x-2 is 1.56

Answer:

f(x) =11

Step-by-step explanation:

Replace x with 4

f(4) = 2(4) + 3

multiply

f(4)= 8+3

add

f(4) = 11

Answer:

Step-by-step explanation:

1. 24+9/2pi, 2. 51 3. 86. 4. 90 5. 56, all of these are done with the addition or subtraction of simple geometric formulas such as those for a rectangle,circle or triangle.

Answer:

Step-by-step explanation:

1. Rectangle + Semi-Circle

[tex]A = a*b + \frac{\pi r^{2}}{2}\\a=6, b=4, r=\frac{a}{2} = 3\\A = 24 + 4.5 \pi = 38.14 in^{2}\\[/tex]

2. Large Rectangle - Small Rectangle

[tex]A = 15 * 5 - 6*3 = 75 - 18 = 57 in^{2}\\[/tex]

3. Rectangle - Trapezoid

[tex]A = a * b - \frac{c+d}{2}h = 20*17 - 6 * \frac{6+12}{2} = 340 - 54 = 286 cm^{2}\\[/tex]

4. The composite figure is a rectangle if the triangle is moved to left and fills the missing part

[tex]A = a * b = 10 * 9 = 90 m^{2}\\[/tex]

5. Square - Triangle

A = [tex]A = a^{2} - \frac{b^{2}}{2} = 8 * 8 - \frac{4 * 4}{2} = 64 - 8 = 56 cm^{2}\\[/tex]

6. Circle - Square

[tex]A = \pi r^{2} - a^{2} = 64 \pi - 12 * 12 = 64 \pi - 144 = 57.06 m^{2}[/tex]

7. Square - Triangle

[tex]A = a^{2} - \frac{b*h}{2} = 15 * 15 - \frac{10 * 8}{2} = 225 - 40 = 185 sq.ft.[/tex]

8. Rectangle + Triangle

[tex]A = a *b + \frac{a*h}{2} = 9.5 * 9 + \frac{9.5*12}{2} = 85.5 + 57 = 142.5 in^{2}\\[/tex]

9. Triangle + Rectangle

[tex]A = \frac{a*b}{2} + c * d = \frac{12*10}{2} + 12 * 6 = 60 + 72 = 132 sq.ft.[/tex]

10. Rectangle + Quarter Circle

[tex]A = r * b + \frac{\pi r^{2}}{4} = 6 * 8 + \frac{36 \pi}{4} = 48 + 9 \pi = 76.27 in^{2}\\[/tex]

11. Square + Rectangle

[tex]A = a^{2} + b * c = 7 * 7 + 9 * 14 = 49 + 126 = 175 m^{2}[/tex]

12. Rectangle - 2 * Square

[tex]A = a * b - 2 * c^{2} = 25 * 18 - 2 * 8 * 8 = 450 - 128 = 322 sq.ft.[/tex]

13. Trapezoid

[tex]A = \frac{a+b}{2} * h = \frac{10+15}{2} * 15 = 12.5 * 15 = 187.5 sq.ft.[/tex]

14. Trapezoid - Rectangle

[tex]A = a * h - c * d = 12 * 7 - 9 * 5 = 84 - 45 = 39 in^{2}[/tex]

15. Rectangle - Triangle

[tex]A = a * b - \frac{a * b}{2} = \frac{a*b}{2} = \frac{10 * 20}{2} = 100 in^{2}[/tex]

16. Square + Trapezoid

[tex]A = a^{2} + \frac{a + b}{2} * h = 25 + \frac{5 + 9.5}{2} * 6 = 25 + 43.5 = 68.5 in^{2}[/tex]

Answer:

36

Step-by-step explanation:

well you could add 24+12 which equals 36

Answer:

A.

Step-by-step explanation:

Give the data set: 2, 4, 6, 8, 10, 12.

Find the following:

Min, Q1, Median, Q3, and Max.

Min. = 2

Q1 = 4

Median = (6+8)/2 = 7

Q3 = 10

Max = 12

Check the box plot to see which one represents these values above.

Thus:

The correct box plot would have the whisker to your left at 2, representing the min value.

The Q1 would be at represented by the beginning box the edge of the rectangular box that starts at 4.

The median would be represented by the vertical line that divides the box which would be on 7.

The Q3 would be on the end of the box which is at 10.

The max would be represented by the other whisker that goes to our right, representing 12.

The box plot is that represents this data is the box plot given in option A.

Use the given point to find the y-intercept:

The line is:

Answer:

[tex]15.394\ \text{feet}[/tex]

Step-by-step explanation:

Let [tex]x[/tex] be the length and width of the base of the prism and,

[tex]y[/tex] be the height of the prism.

Now height of the prism is 2 feet less than the length and width.

So [tex]y=x-2[/tex]

Volume of the the square prism is [tex]3174\ \text{ft}^3[/tex]

[tex]x^2y=3174[/tex]

Now we graph both the functions.

The point at which they intersect each other is [tex](15.394,13.394)[/tex]

So, the length of the prism is [tex]15.394\ \text{feet}[/tex].
