Answer:

D - 9 students

Step-by-step explanation:

For this problem, you need to find the percentage of students left. Subtracting all the percentages you already know, you get 100 -  30 - 20 - 10 - 10, or 30. Since there are 30 students in the class, 30 percent of 30 is 9 students.

Hopefully this helps- let me know if you have any questions!

There are 5 numbers that can be used.

The first digit can be 1 of 5

The second digit can be 1 of 4

The third digit is 1 of 3

The fourth digit is 1 of 2

The fifth digit is 1 of 1

Total digits that can be created = 5 x 4 x 3 x 2 x1 = 120

Answer:

40

Step-by-step explanation:

let the unknown be y (x is used as times(multiplication) )

(y-17)x-6=-138

add /-6 to both sides

y-17x-6/-6=-138/-6

y-17=23

make y independent/add 17 to both sides

y-17+17=23+17

y=40

or in an easier way

-138/-6 =23

23+17=40

Complete Question:

Lucas is planting grass on the shaded portions of the yard. What will be the total area of covered by grass? Fill in the missing.

Part A= 12 x ? = ? ft²

Part B= 0.5 x ? x 9 = ?ft²

Part C= 0.5 x 7 x ? = ?ft²

Total Area= ?ft²

Answer:

[tex]A = 108ft^2[/tex]

[tex]B = 27ft^2[/tex]

[tex]C = 24.5ft^2[/tex]

[tex]Area = 159.50ft^2[/tex]

Step-by-step explanation:

Given

See attachment

From the attachment;

Part A is a rectangle with dimension 9ft by 12ft

So,

[tex]A = 12ft * 9ft[/tex]

[tex]A = 108ft^2[/tex]

Part B is a triangle with dimension: height = 6 and base = 9

The height is calculated as:

[tex]Height = 12ft - 6ft = 6ft[/tex]

And the base is:

[tex]Base = 18ft - 9ft = 9ft[/tex]

So, the area is:

[tex]B = 0.5 * 6ft * 9ft[/tex]

[tex]B = 27ft^2[/tex]

Part C is a triangle with dimension: height = 7 and base = 7

So, the area is:

[tex]C = 0.5 * 7 * 7ft^2[/tex]

[tex]C = 24.5ft^2[/tex]

Total Area is:

[tex]Area = A + B + C[/tex]

[tex]Area = 108ft^2 + 27ft^2 + 24.5ft^2[/tex]

[tex]Area = 159.50ft^2[/tex]

Answer:

12x + 11y = 6569 (X is adult ticket, Y is senior ticket)

Y = 2x - 21

Now to plug it in:

12x + 11(2x-21) = 6569

12x+22x-231 = 6569

34x = 6569 + 231 = 6800

34x = 6800

x = 200

y = 379

200 adult tickets were sold and 379 senior tickets were sold.

I just want to mention that the question is wrongly written!

it's meant to be  x² − 10x − 11 = 0 and not x2 − 10x − 11 = 0

and so the other equations!

Answer:

The answer is B: (x − 5)² = 36

Step-by-step explanation:

by solving the equations using the quadratic formula we found:

the solutions for x² − 10x − 11 = 0 | x = 11, -1

the solutions for A | x = 16, 4

the solutions for B | x = 11, -1

the solutions for C | x = [tex]\sqrt{21} +5[/tex], [tex]-\sqrt{21}+5[/tex]

the solutions for D | x = [tex]\sqrt{21}+10, -\sqrt{21}+10[/tex]

the given equation: x² − 10x − 11 = 0 and the equation B: (x − 5)² = 36 have the same solutions

Therfore B is the correct answer

Answer:

  9) 39.7°

  10) insufficient information

  11) 20.0 in

  12) 19.0 m

Step-by-step explanation:

These Law of Sines problems are all worked the same way. For sides a, b, and opposite angles A, B, the relevant relationship is ...

  a/sin(A) = b/sin(B)

This gives rise to formulas for angle and side:

  A = arcsin(a/b·sin(B))

  a = b·sin(A)/sin(B)

If the longest given side is not opposite the largest given angle, there may be two solutions.

_____

9) B = arcsin(8/12.5·sin(87°)) = 39.7°

10) missing a side or angle; insufficient information

11) f = (5 in)·sin(70.4°)/sin(13.6°) = 20.0 in

12) p = (22 m)·sin(59°)/sin(180°-59°-24°) = 19.0 m

Answer:

$32.80

Step-by-step explanation:

Find out how much Nancy spent on 4 violins and 2 song books.

1 violin = 87.82

4 violins = 87.82 x 4 = 351.28

1 song book = 7.96

2 song books = 7.96 x 2 = 15.92

351.28 + 15.92 = 367.20

4 x 100 dollar bills = 400 dollars

Normally after paying for an item, if you pay much more money than the actual price of the item, you'll get some money back from the cashier. That's called a change.

400 - 367.20 = 32.80

Answer: the answer is 4

Step-by-step explanation:

11 users waited more than a hour but not more than 2 hours.

A histogram is a graphical depiction of continuous or discrete data. In a histogram, the frequency is represented by the area of a bar. Frequency density, which is proportional to frequency, is plotted on the y-axis, and intervals representing the range of values are plotted on the x-axis.

From the Histogram we have

For 0 -30 minutes - 5 users wait

31- 60 minutes- 4 users wait

61- 90 minutes- 9 users wait

91- 120 minutes- 2 users wait

120- 150 - 4 users wait

So, the number of users waited more than a hour but not more than 2 hours

= 9 + 2

= 11 users

Answer:

HL  (Hypotenuse-Leg)

x = 13

Step-by-step explanation:

hypotenuse GJ is shared by both triangles.

∠H and ∠K are right angles so they are right triangles.

leg HG = leg KG

so HL theorem

x + 5 = 8

x = 13

(Right angle, hypotenuse and side theorem)

By this theorem GK = GH ,

=> x + 5 = 8

=> x = 8-5

Answer:

Hello the reference related to your question is missing attached below is the reference

answer : p ( x - y ≥ 1 ) = 0.0019

Step-by-step explanation:

Assuming 'X' and 'Y' are independent random samples

X : mean value = [tex]U_{1}[/tex] , variance = 0.4 /10 = 0.04

Y : mean value = [tex]U_{2}[/tex] , variance = 0.8/10 = 0.08

since the values are independent

V [ X - Y ] = V [ X ] + V [Y ] = 0.04 + 0.08 = 0.12

Determine the probability that the sample mean for species A exceeds the sample mean for species B by at least 1 unit

P ( x - y ≥ 1 ) = 0.0019

Answer:

The right solution is "-8.25".

Step-by-step explanation:

The given values are:

Sampled people,

n = 150

Null and alternative hypotheses will be:

[tex]H_0:p=0.53[/tex]

[tex]Ha:p\neq 0.53[/tex]

The z-statistics will be:

⇒ [tex]z=\frac{\bar{p}-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }[/tex]

On substituting the values, we get

⇒    [tex]=\frac{0.2-0.53}{\sqrt{\frac{0.53(1-0.53)}{150} } }[/tex]

⇒    [tex]=\frac{-0.33}{\sqrt{\frac{0.24}{150}} }[/tex]

⇒    [tex]=\frac{-0.33}{0.04}[/tex]

⇒    [tex]=-8.25[/tex]

Answer:

104

Step-by-step explanation:

Hey There!

So essentially what this problem is asking us to do is solve for the missing angle in a triangle

Remember all of the angles in a triangle will add up to 180

so to find the missing angle we subtract the given angles (38 and 38) from 180

180-38-38=104

so we can conclude that angle A equals 104
