Answer:

The average weight of a 3-pound human brain in ounces is approximately 48 ounces.

To find the measure of angle G in triangle FGH, we can use the fact that the sum of angles in a triangle is always 180 degrees.

First, we can find the measure of angle H using the fact that the sum of angles in a triangle is 180 degrees:

H = 180 - F - G

H = 180 - 72 - G

H = 108 - G

Next, we can use the Law of Cosines to find the length of side FG:

FG^2 = GH^2 + FH^2 - 2(GH)(FH)cos(F)

FG^2 = 8^2 + 13^2 - 2(8)(13)cos(72)

FG^2 = 169.21

FG ≈ 13.01 ft

Finally, we can use the Law of Cosines again to find the measure of angle G:

cos(G) = (FG^2 + GH^2 - FH^2) / (2(FG)(GH))

cos(G) = (169.21 + 64 - 169) / (2(8)(13))

cos(G) = 0.7686

G ≈ 40.6 degrees

Therefore, the measure of angle G in triangle FGH is approximately 40.6 degrees.

Answer: 18:21

Answer: The total number of tickets sold (student and adult) cannot exceed 110, so we can write the first inequality as:

r + y ≤ 110

The minimum amount of money needed from ticket sales is $720, so we can write the second inequality as:

4r + 9y ≥ 720

To graph the system of inequalities, we can start by plotting the two lines corresponding to r + y = 110 and 4r + 9y = 720. The solution to the system of inequalities is the area on the graph that is shared by both of the inequalities (i.e., the area above the line 4r + 9y = 720 and below the line r + y = 110).

One possible solution for the number of student tickets (r) and adult tickets (y) is (30, 80). This means that 30 student tickets and 80 adult tickets can be sold to meet the conditions and raise at least $720.

For the statement "Integer x divisible by 6" the option C is correct.

Either statements are NOT sufficient, but BOTH together are sufficient.

What is integer?

The Latin term "Integer," which implies entire or intact, is where the word "integer" first appeared. Zero, positive numbers, and negative numbers make up the particular set of numbers known as integers.

(1) x + 3 is divisible by 3

This means that x is a multiple of 3.

Hence x + 3 is a multiple of 3.

But x could be 0, 3, 6. If x = 3, x is not divisible by 6.

Otherwise it is.

So, this statement is insufficient.

(2) x + 3 is an odd number

This means that x is an even number.

X can be 6, or 10.

So, this statement is insufficient.

Together -

From (1) it is known that x is a multiple of 3.

Hence X can be 0,3,6,9,12,15,18,21,24,27,30.

From (2) it is known that x is even.

Hence X can be 0,6,12,18,24,30.

Therefore, x is divisible by 6.

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Let the percentage Tallulah have to put down in order to pay be A

Now , the equation will be

The price of the car = $ 18,500

The amount of money Tallulah can get from the bank = $ 15,725

So , the remaining amount = price of the car - amount of money Tallulah can get from the bank

Substituting the values in the equation , we get

The remaining amount = 18,500 - 15,725

The remaining amount = $ 2,775

Now , $ 2,775 = A % of price of the car

Range = 7. IQR = 4.5. Variance: 8.67, Std Dev: 2.96 when researcher organized diet groups on weight loss weighed five clients after several weeks on the program.

The range of the weight-loss scores can be calculated by subtracting the smallest value from the largest value. In this case, the range would be

13 - 6 = 7.

The inter-quartile range (IQR) is calculated as the difference between the 75th percentile and the 25th percentile of the data.

IQR: 11.25 - 6.75 = 4.5

To calculate the variance, first find the mean weight-loss score by summing all the scores and dividing by the number of clients: (13 + 12 + 6 + 9 + 9 + 10) / 6 = 9.17. Next, subtract the mean from each score and square the result for each client:

[tex](13 - 9.17)^2 = 3.69\\(12 - 9.17)^2 = 1.69\\(6 - 9.17)^2 = 16.0\\(9 - 9.17)^2 = 0.02\\(9 - 9.17)^2 = 0.02\\(10 - 9.17)^2 = 0.69[/tex]

Next, sum the squared deviations and divide by the number of clients minus one (n-1):

(3.69 + 1.69 + 16.0 + 0.02 + 0.02 + 0.69) / (6-1) = 4.83

The variance is 4.83 and the standard deviation is the square root of the variance: [tex]\sqrt{(4.83)} = 2.19.[/tex]

Answer: 6x=90

Step-by-step explanation:

We know that one angle in a right triangle is 90 degrees and the sum of all the angles is 180, so we can start by subtracting 90 from 180. We are left with 90 and now we have angle ratios which represent fractional quantities. We know that one of these quantities is 5 and the other is 1. Their sum is 6 and equals 90. So the proportion would be 6x = 90. The larger angle is 75 degrees and the smaller one is 15.

Answer: 44%

Step-by-step explanation:

100 - 49 - 7 = 44 people who preferred Soda B

44 of a 100 = 44%

Answer: 44%

Step-by-step explanation:

Since we have 100 people, each person is one percent.

49 people preferred A, so we can subtract 49 from 100.

100 - 49 = 51

7 people didn't have an opinion, so we can subtract 7 from 51.

51 - 7 = 44

That means that 44 people preferred B, which is 44%

The first six terms of the sequence are 2, 1, 3, 4, 7, and 11.

The 12th term is 199.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(1) = 2

f(2) = 1

f(n) = f(n - 1) + f(n - 2)

Now,

For n = 3,

f(3) = f(3 - 1) + f(3 - 2) = f(2) + f(1) = 1 + 2 = 3

f(4) = f(4 - 1) + f(4 - 2) = f(3) + f(2) = 3 + 1 = 4

f(5) = f(5 - 1) + f(5 - 2) = f(4) + f(3) = 4 + 3 = 7
