Some algae contains up to 50% oil by weight. How much oil is in a 7.3-ounce sample of this type of algae?This would help if you could solve anyone.

Answers

Answer 1

Answer:

Answer: 3.65

Step-by-step explanation:

This question is asking basically what is 50% or 1/2 of 7.3.

Let's expand the number 7.3

Then, we end up getting 7.30.

We have to find 1/2 of 7.30.

$(1)/(2)$ of 7.30 = $3.65$

Hope this helps you!

WILL GIVE MOST BRAINIESTWhich of the following functions best describes this graph?
A. y (x + 4) (x + 5)

Answers

Answer:

D. y =

Step-by-step explanation:

The solutions to this graph (meaning when y equals 0 or when the graph crosses the x-axis) are 4 and 5.

The only answer choice that has the solutions 4 and 5 when you factor it out is D.

Here's the proof:

$x^(2) -9x + 20$

Factors of 20: - 5 & -4

Sums that add up to -9: -5 + (-4)

$x^(2) -4x-5x+20$

(factor the first two terms and the last two terms separately)

$(x^(2)-4x)(-5x+20)$

$x(x-4) -5(x-4)$

(x - 5) (x - 4)

Let S = {a, b, c). Find the following:a) the number of reflexive relations on S

b)the number of reflexive and symmetric relations on S

Answers

Answer:

The number of reflexive relations on S is 64.

The number of reflexive and symmetric relations on S is 8.

Step-by-step explanation:

Consider the provided set S = {a, b, c}.

The number of elements in the provided set is 3.

Part (a) the number of reflexive relations on S

To calculate the number of reflexive relation on S we can use the formula as shown:

Total number of Reflexive Relations on a set: $2^(n(n-1))$ .

Where, n is the number of elements.

In the provided set we have 3 elements, so substitute the value of n in the above formula:

$2^(3(3-1))$

$2^(3(2))$

$2^(6)$

$64$

Hence, the number of reflexive relations on S is 64.

Part(b) The number of reflexive and symmetric relations on S.

To calculate the number of reflexive and symmetric relation on S we can use the formula as shown:

Total number of Reflexive and symmetric Relations on a set: $2^{(n(n-1))/(2)}$ .

Where, n is the number of elements.

In the provided set we have 3 elements, so substitute the value of n in the above formula:

$2^{(3(3-1))/(2)}$

$2^{(3(2))/(2)}$

$2^{(6)/(2)}$

$2^(3)$

$8$

Hence, the number of reflexive and symmetric relations on S is 8.

HOME Realty claims that it can sell a detached, residential house faster than any other realty company. With the aim of examining HOME's claim, you sample 20 customers who sold a detached, residential house through HOME and record the selling times (in days) of the houses. Your data are summarized below:Selling Time Frequency
0 10 3
10 20 4
20 30 6
30 40 4
40 50 3

Find the proportion of selling times in the sample that are less than 20 days claims that it can sell a detached, residential house faster than any other realty company.

Answers

Answer:

0.35

Step-by-step explanation:

Given the data:

Selling Time___ Frequency

0 10____________3

10 20__________ 4

20 30__________ 6

30 40__________ 4

40 50__________ 3

Proportion of selling time in sample above that are less Than 20 days :

Taking the sum of the frequency :

Hence, total frequency = (3 + 4 + 6 + 4 + 3) = 20

Selling time which is less Than 20 days :

(0 - 10) = 3

(10 - 20) = 4

Total = (3 + 4) = 7

Proportion = selling time less Than 20 days / total frequency

= 7 / 20

= 0.35

One question in the survey asked how much time per year the children spent in volunteer activities. The sample mean was 14.76 hours and the sample standard deviation was 16.54 hours.Required:a. Based on the reported sample mean and sample standard deviation, explain why it is not reasonable to think that the distribution of volunteer times for the population of South Korean middle school students is approximately normal. b. The sample size was not given in the paper, but the sample size was described as large. Suppose that the sample size was 500. Explain why it is reasonable to use a one-sample t confidence interval to estimate the population mean even though the population distribution is not approximately normal. c. Calculate and interpret a confidence interval for the mean number of hours spent in volunteer activities per year for South Korean middle school children.
