[tex]w=5x^2- 2x + 3[/tex]

The area of a rectangle is defined as

[tex]A=w \times h[/tex]

Where [tex]w[/tex] is width and [tex]h[/tex] is height.

Replacing each equivalence, we have

[tex]A=2(5x^2- 2x + 3)\\A=10x^{2} -4x+6[/tex]

Answer:

114.5 in³

Step-by-step explanation:

Volume of cone:

⅓ × 3.14 × 8² × 12

= 803.84 cm³

Volume of hemisphere:

⅔ × 3.14 × 8³

= 1071.786667 cm³

Total = 803.84 + 1071.786667

= 1875.626667 cm³

1 cm = 0.393701 inches

1 cm³ = 0.393701³ inches

Volume in in³:

1875.786667/0.393701³

= 114.4579471 in³

Answer:

[tex] \frac{1}{3 } [/tex]

Step-by-step explanation:

5 which is the number of tulips divide by 15 which is the total number of flowers

(I'm not sure tho)

The experimental probability that Amelie picks a tulip next is 1/3, calculated by dividing the number of tulips (5) she has already picked by the total number of flowers picked (15).

The experimental probability that the next flower Amelie picks will be a tulip is based on her past experience of picking flowers. Since she has picked 15 flowers and 5 were tulips, we divide the number of tulips by the total number of flowers picked to get the probability of picking a tulip.

To calculate this, use the formula for experimental probability: Probability = (Number of successful outcomes) / (Total number of trials). In Amelie's case, this would be 5 tulips divided by 15 flowers, giving a probability of 1/3, or approximately 0.333.

Thus, the experimental probability of picking a tulip next is 1/3.aa

Answer:

4.11%

Step-by-step explanation:

Gain on stock a:

(21.15 × 100) × 6/100

126.9

Loss on stock b:

(14.23 × 50) × 1.5/100

10.6725

Net gain:

126.9 - 10.6725

116.2275

Total share value:

(21.15 × 100) + (14.23 × 50)

2826.5

% gain:

116.2275/2826.5 × 100

4.112064391%

your percentage gain on your 2 stock portfolio will be 4.11%.

Given,

The per share cost of stock "a" is $21.15 .

So the total cost of 100 shares of stock "a" will be,

[tex]21.15\times100=2115[/tex] dollars.

The per share cost of stock "b" is $14.23 .

So, the total cost of 50 shares of stock "b" will be,

[tex]14.23\times50=711.5[/tex] dollars.

Total investment on both the shares will be,

[tex]2115+711.5=2826.5[/tex] dollars.

Since stock "a" gained 6% today, so total gain in stock "a" will be,

[tex]\dfrac{2115\times 6 }{100}=126.9[/tex] dollars.

Now, share "b" lost 1.5% today, so total loss in stock "b" will be,

[tex]\dfrac{711.5\times1.5}{100} =10.67[/tex] dollars.

Now, overall gain in both the shares will be,

[tex]126.9-10.67=116.22[/tex] dollars.

Percentage gain will be,

[tex]\dfrac{116.22}{2826.5} \times 100\%=4.11\%[/tex]

Hence your percentage gain is 4.11%.

Answer:

mean: 3.2 standard deviation: 1.4

Step-by-step explanation:

its correct

The mean number of males selected each month is 3.2, and the standard deviation is approximately 1.4 males.

The student's question is about finding the mean and standard deviation of the number of males selected each month to have lunch with the CEO in a division of a company. Given that 40% of the employees are male, we can determine the mean number of males selected for the lunch by multiplying the percentage of males by the number of employees selected each month, this is known as the expected value, E(X) = np. Since 40% of over 200 employees are male, we assume we have at least 80 males (0.40 x 200) in the division. If 8 employees are selected at random, the mean number of males expected, μ, would be 40% of 8, or 3.2 males.

To find the standard deviation, σ, we use the formula for the standard deviation of a binomial distribution, which is σ = sqrt(np(1-p)), where p is the probability of choosing a male (0.40) and n is the total number selected (8). In this case, the standard deviation is σ = sqrt((8)(0.40)(0.60)) and rounding to the nearest tenth gives us σ ≈ 1.4.

Answer:A contractor finds that Crew A takes 5(1/2) hours to construct a retaining wall and Crew B can do the same job in 7(1/2) hours.

If Crew A and Crew B work together, how long will it take them to construct the retaining wall?

a) Let h = the time to complete the job. Write the equation you would use to solve this problem.

:

let the completed job = 1, each will do a fraction of the job which adds up to 1

h%2F5.5 + h%2F7.5 = 1

Step-by-step explanation:f means fraction 2/5.5 2/7.5

Final answer:

Together, they will complete the wall in approximately 3.34 hours (about 3 hours and 20 minutes).

Explanation:

To determine how long it will take for crew A and crew B to construct a retaining wall together, we can use the concept of rates of work. We first find the rate at which each crew can complete the job individually and then combine their rates.

Crew A takes 5.5 hours to construct the retaining wall, which means their rate of work is 1 wall per 5.5 hours or 1/5.5 walls per hour.

Crew B takes 8.5 hours, so their rate is 1 wall per 8.5 hours or 1/8.5 walls per hour.

When both crews work together, you can add their rates:

Rate of A + Rate of B = Combined Rate

1/5.5 + 1/8.5 = Combined Rate

To find the combined rate, you find a common denominator and add the fractions:

Combined Rate = (8.5 + 5.5) / (5.5 × 8.5)

Combined Rate = 14 / 46.75

The combined rate is approximately 0.2995 walls per hour. To find the total time it takes for both crews to construct the wall, you take the reciprocal of the combined rate:

Total time = 1 / Combined Rate

Total time = 1 / 0.2995

This gives us the total time of approximately 3.34 hours (or roughly 3 hours and 20 minutes) for both crews working together to construct the retaining wall.

Answer: 125,000 BTUs

Step-by-step explanation:

Hi, to answer this question we have to apply proportions:

A fuel tank has a volume of 36 gallons. When filled with biodiesel, it provides 4,500,000 BTUs

So, the proportion is:

36 gallons / 4,500,000 BTUs

For 1 gallon  

1 gallon / x BTUs

36/4,500,000 = 1/x

Solving for x:

x = 1 / (36/4,500,000)

x = 125,000 BTUs

Answer:

5/168

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome.

According to the question, if the bag contains 5 red raffle tickets, 7 blue raffle tickets and 2 green raffle tickets, the total number of ticket is given as:

5+7+2 = 14tickets

The total outcome = 14.

If Jackie selects a green ticket on her first two selections, the probability of selecting a green twice from the bag and replacing it will be 2/14×2/14 = 4/48.

Note that the total number of ticket remains complete each time she selects since the ticket was always REPLACED.

If Jackie picks a red on her third selection, the probability of picking a red will be 5/14.

The probability that she selects a green ticket on her first two selections and a red ticket on her third selection will then be:

= 4/48 × 5/14

= 1/12×5/14

= 5/168

Answer:

5/686

Step-by-step explanation:

Red raffle tickets=5

Blue raffle tickets=7

Green raffle tickets= 2

Total raffle tickets=14

Three tickets were selected randomly with replacement

Probability of selecting Green tickets on her first two selections and red tickets on her third selection =propability of selecting Green raffle tickets twice and red raffle tickets once

=2/14×2/14×5/14

=1/7×1/7×5/14

=1/49×5/14

=5/686

Note: There are two green tickets and since it is selected with replacement, the total green tickets and the total raffle tickets doesn't change.

Answer:

7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1/6

Step-by-step explanation:

7 3/4 + 1 3/4 - 3 5/6

we do not want the minus sign.

7 3/4 + 1 3/4 - 3 5/6 = 7 3/4 + 1 3/4 - 3  -   5/6

7 3/4 + 1 3/4 - 3 5/6 =  7+  3/4 + 1 +  3/4 - 3  -  5/6

7 3/4 + 1 3/4 - 3 5/6 = 7 + 1 - 3 + 3/4 + 3/4 - 5/6

7 3/4 + 1 3/4 - 3 5/6 = 5 + 3/4 + 3/4 - 5/6

7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1 - 5/6

7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1/6

To rewrite the expression 7 3/4 + 1 3/4 - 3 5/6 using addition instead of subtraction, we can change the sign of the subtraction term and find the common denominator to add the fractions.

To rewrite the expression 7 3/4 + 1 3/4 - 3 5/6 using addition instead of subtraction, we can change the subtraction to addition by changing the sign of the second term. So the expression becomes:

7 3/4 + 1 3/4 + (-3 5/6)

Now, to add fractions with different denominators, we need to find the common denominator. In this case, the common denominator is 12.

Converting all the fractions to have a denominator of 12, we get:

7 9/12 + 1 9/12 + (-3 10/12)

Adding the numerators, we have:

7 + 9 + 1 + 9 - 3 - 10 = 13

So the expression 7 3/4 + 1 3/4 - 3 5/6, using addition instead of subtraction, is equal to 13.
