A jelly bean factory packaged 913 special ordered bags last Tuesday. The shift manager randomly picked seven bags to count the number of jelly beans.
8, 6, 11, 15, 6, 11, 6

If the sample was representative of all the bags packaged on Tuesday, what was the mode of the number of jelly beans of all the bags?
A. 6
B. 15
C. 8
D. 11

Answers

Answer:

I think the answer is 1/5

Step-by-step explanation:

Add up the total number of jellybeans, 20 + 45 + 30 + 5 = 100.  

Divide the number of watermelon jellybeans by the total: 20/100 and reduce the fraction to 1/5.

Hope this help you! :)

Josh can long-jump 195% of his height with a running start. If Josh is 66 inches tall, how far can he long-jump?

Answers

Answer: 128.7 inches

Step-by-step explanation:

Josh's height is 66 inches.

When he jumps with a running start, he can jump as far as 195% of his height.

The length he can jump is therefore 195% multiplied by his height:

= Josh height * 195%

= 66 * 195/100

= 128.7 inches

Answer:

I am not sure but for

CAE it is 65˚

CBD it is 65˚

Step-by-step explanation:

x+40=3x-10

Move the 3x to the other side by subtracting by 3x on both sides

x-3x+40=3x-3x-10

The equation now looks like this:

-2x+40=-10

Move 40 to the other side by subtracting 40 both sides:

-2x+40-40=-10-40

-2x=-50

Divide by -2 on both sides:

-2x/-2=-50/-2

x=25

Since we found out what x is we can replace x in both CAE and CBD:

For CBD: 25+40 is 65

For CAE: 3(25)-10 is 65

Answer:

m∠CAE = 65, m∠CBD = 65

Step-by-step explanation:

Line CA is a transversal of lines AE and BD which are parallel, in this case corresponding angles are congruent. ∠CAE and ∠CBD are corresponding angles so you can make them equal to each other. x+40=3x-10 -> 2x=50 ->x=25. Now that we have x just plug it into the equations 25+40=65 which is m∠CBD. 3(25)-10=75-10=65 is m∠CAE

What is the mathematical
representation of 20P4?

Answers

the answer for 20p4 is c

The mathematical representation of 20P4 is [tex]^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]. so option C is the correct.

How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?

We can use combinations for this case,

The Total number of distinguishable things is m.

Here, Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in total of

[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]

If the order matters, then each of those choice of k distinct items would be permuted k! times,

So, total number of choices in that case would be:

[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]

This is called permutation of k items chosen out of m items (all distinct).

We have to find the mathematical representation of 20P4.

[tex]^{20}P_4[/tex]

here, m = 20

k = 4

Now substitute;

[tex]^mP_k = \dfrac{m!}{ (m-k)!}\\\\^{20}P_4 = \dfrac{20!}{ (20-4)!}\\\\^{20}P_4 = \dfrac{20!}{ (16)!}\\\\\\^{20}P_4 = \dfrac{20 \times 19 \times 18 \times 17 \times 16!}{ (16)!}\\\\\\^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]

Hence, the mathematical representation of 20P4 is [tex]^{20}P_4 = 20 \times 19 \times 18 \times 17[/tex]. so option C is the correct.

Liam and his children went into a restaurant and where they sell drinks for $2 each and tacos for $3.50 each. Liam has $30 to spend and must buy at least 9 drinks and tacos altogether. If Liam decided to buy 5 tacos, determine the maximum number of drinks that he could buy. If there are no possible solutions, submit an empty answer.

Answers

answer: the maximum number of drinks Liam can buy is 4 without over exceeding his price limit.

work:
$3.50 for 5 tacos is $17.50
9 - 5 tacos = 4 drinks
4 drinks x $2 = $8
$17.50 + $8 = $25.50 out of $30 price limit

7. (07.03) An equation is shown below: 4(2x - 5) + 15 = 11 Write the steps you will use to solve the equation and explain each step. (5 points)​

Answers

Answer:

x = 2

Step-by-step explanation:

[tex]4(2x-5)+15 = 11 => 4(2x-5) = 11 - 15 => 4(2x-5) = -4 => 2x-5 = \frac{-4}{4} => 2x-5 = -1 => 2x = -1 + 5 => 2x = 4 => x = 2[/tex]

The value of x is 2 for equation 4(2x - 5) + 15 = 11

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is 4(2x - 5) + 15 = 11

Four times of two x minus five plus fifteen equal to eleven

4(2x - 5) + 15 = 11

Apply distributive property on the LHS

8x-20+15=11

8x-5=11

Add 5 on both sides

8x=16

Divide both sides by 8

x=2

Hence, the value of x is 2 for equation 4(2x - 5) + 15 = 11

Step-by-step explanation:

4+2(8²×4²)+6+4+6+6+6+2+2​ = 4+2(64*16)+6+4+6+6+6+2+2 = 4 + 2048 + 6 * 5 + 2 = 4 + 2050 + 30 = 2080+4 = 2084​

4 + 2(8^2 * 4^2) + 6 + 4 + 6 +6 + 6 + 2 + 2
