Final answer:

A 66-kg person contains approximately 39.6 kilograms of water, considering that the human body is comprised of about 60% water.

Explanation:

To estimate how many kilograms of water is in a 66-kg person, biology and a general understanding of the human body composition are required. The human body is comprised of approximately 60% water. Thus, to calculate the mass of water in a 66-kg person, the following calculation is performed:

Water mass = Total body mass x Percentage of water in the body

Water mass = 66 kg x 0.60

Water mass = 39.6 kg

Therefore, a 66-kg person contains approximately 39.6 kilograms of water.

To solve the equation mn + 7p = 8 for p, subtract mn from both sides to get 7p = 8 - mn, then divide by 7 to isolate p, resulting in p = (8 - mn) / 7.

To solve the equation mn + 7p = 8 for p, we need to isolate p on one side of the equation. We can do this by performing the following steps:

Now, the variable p is isolated, and the equation shows p in terms of m and n.

The provided reference solution and the graphing technique are not directly applicable to this algebra problem, as they pertain to different cases with specific contexts such as elasticity and supply-demand curves. For the actual question at hand, we focused exclusively on algebraic manipulation to find the value of p.

Answer:

statement A, C, D, are true.

Step-by-step explanation:

We check all the statements by the rule of 72 to find which statement about doubling an investment are true.

Formula we use = [tex]\frac{72}{R}[/tex]  R = Rate of interest

Statement A :

An investment of $5,000 will double in 6 years at an annual compound interest rate of 12%.

 [tex]\frac{72}{12}[/tex] = 6 years

It will take 6 years to double the investment. This statement is true.

Statement B :

An investment of $1000 will double at an annual compound interest rate of 18% in 6 years.

[tex]\frac{72}{18}[/tex] = 4 years

It will take 4 years to double the investment. This statement is not true.

Statement C:

An investment of $350 will double in 9 years at a compound interest rate of 8%.

[tex]\frac{72}{8}[/tex] = 9 years

It will take 9 years to double the investment. This statement is true.

Statement D :

An investment of $2000 will double at a simple interest rate of 5% in 20 years.

Formula for Simple interest = (PRT)

                                           I  = (2000 × 0.05 × 20) = $2000

So the amount will be 4000 in 20 years. This statement is true.

Statement E :

An investment of  $700 will double in 12 years at a simple interest rate of 6%

Interest = ( 700 × 0.06 × 12 ) = $504

Amount after 12 years 700 + 504 = $1204. This statement is not true.

Answer: Shakira bowled 4 games.

Step-by-step explanation:

Hi, the total cost for Shakira (21) is equal to the multiplication of the price of each game of bowl  (4.75) and the number of games bowled (g), plus the cost of the shoes rental (3).

3 + 4.75 g = 21

Solving for g:

4.75 g = 21-3

4.75 g = 18

g= 18/4.75

g = 3.78 = 4 games (rounded)

Xavier's rate per hour is $11.20.

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

Given that, Xavier worked 10 hours on Monday and 15 hours on Wednesday. His total pay was 280.00

Number of hours worked on Monday = 10 hours

Number of hours worked on Tuesday = 15 hours

Total pay received by Xavier = $280

Total number of hours worked  = (10 + 15) = 25 hours

Therefore, Rate per hour = 280/25 dollars per hour

Hence, Xavier's rate per hour is $11.20.

add the 2 sets of numbers

-5 +-7 = -12

-3 +-1 = -4

 Answer is B

Trey can expect to make approximately 30 out of 75 free throw shots based on his previous success rate of 12 out of 30 shots.

To find how many free throws Trey might make out of 75 attempts, we use the proportion of his successful shots in the initial 30 attempts. Trey made 12 out of 30 shots, which is a success rate of  [tex]\( \frac{12}{30} = \frac{2}{5} \).[/tex] We can expect him to maintain this rate over 75 shots:

[tex]\[ \text{Expected shots made} = \left( \frac{2}{5} \right) \times 75 = \frac{2 \times 75}{5} = 30 \][/tex]

Therefore, Trey can expect to make approximately 30 free throws out of 75 attempts. This estimation assumes his skill level and shooting conditions remain consistent throughout the attempts.

This calculation is a basic projection and doesn't account for potential variations in Trey's performance. Factors such as fatigue, practice, and pressure can influence his actual performance. However, it provides a reasonable estimate based on his past performance.

Using this estimate, coaches or analysts can make rough predictions about Trey's potential scoring contribution from free throws in a game or practice session, helping them plan strategies accordingly.

Yes, the total price pay is proportional to the number of tickets.

In mathematics, proportionality indicates that two quantities or variables are related in a linear manner.

Since you never plan to buy the popcorn but only the movie ticket, therefore we can definitely say that there is a direct correlation between the total price and the number of tickets bought.

Since, 1 ticket = $10.50

So,

The proportion equation is:

P = 10.50 t

where P is the total price and t is the number of tickets

Hence,  the total price pay is proportional to the number of tickets.

The equation of the line will be y = ( 2 / 3 )x -2. The correct option is B.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

Given that the line in the image has the points ( 3, 0 ) and ( 0,-2). The equation of the line will be calculated by finding the slope and the y-intercept of the line.

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( -2 - 0 )/ ( 0 - 3 )

Slope = ( 2 / 3 )

y = mx + c

-2 = m 9 0 ) + c

c = - 2

The equation of the line will be written as:-

y = mx + c

y = ( 2 / 3 )x - 2

Final answer:

The median is the best measure of center for the teacher to use to evaluate the overall performance of the class on a test when the data set includes an outlier.

Explanation:

The most appropriate measure of center for the teacher to use in this situation is the median. This is because the median is the best measurement when a data set contains outliers or extreme values that could significantly skew the mean. Since the dataset contains a student score that is significantly lower due to not following instructions, the median would provide a more accurate idea of how the class as a whole performed, as it is less affected by this outlier. On the other hand, the mode might not be as informative if most of the scores are unique, and the mean would be substantially affected by the low score. The range is a measure of spread, not center, and therefore not suitable for determining the average performance.
