b. n3
c. 3n
d. n + n + n

Answers

Answer 1
Answer:

  Answer:

Option (a) is correct.

n + 3 represents the given expression "the sum of 3 and n" correctly.

Step-by-step explanation:

Given : Expression "the sum of 3 and n"

We have to choose the correct option from the given options that represents the given expression "the sum of 3 and n" correctly.

Consider the given expression "the sum of 3 and n"

We know the mathematical symbol for sum is '+'

So, The sum of 3 and n is written mathematically as 3 + n

Thus,  n + 3 represents the given expression "the sum of 3 and n" correctly.

Answer 2
Answer: The answer would be A, yet if this was for homework or a test, you would write it out as "3 + n".

The weight of male Americans between the ages of 18 and 25 is normally distributed, with a mean of 164.5 lb and a standard deviation of 26 lb. One definition of obesity states that a person is obese if the z-score of his or her weight is greater than 2.What is the obesity threshold weight for a young adult American male? Round your answer to the nearest tenth.

Answers

Z- score equal to 2 means 2 standard deviations greater than the mean.
Mean + 2 z = 164.5 + 2 * 26 = 164.5 + 52 = 216.5
Answer: the obesity threshold weight  for a young adult American male is 216.5 lb.

Answers

Adding and subtracting amonomial requires having the same variables. No matter how big or small theircoefficient is, if their variables do not match, they cannot be added or subtracted.The crucial part in adding or subtracting monomials is their sign. If the signsare the same, retain the sign. If the signs are different, subtract and keepthe sign of the larger number.

3x2y + 3xy (cannot be added)
3x2y + (–12x2y) = -9x2y  
3x2y + 2x2y2 (cannot be added)
3x2y + 7xy2 (cannot be added)
3x2y + (–10x2) (cannot be added)
3x2y + 4x2y = 7x2y
3x2y + 3x3 (cannot be added)

A grocer stacks oranges in a four-sided pyramid that is 7 layers high. How many oranges are in the pile? A.504 B.840 C.140 D.120

Answers

Answer:

Option C. 140

Step-by-step explanation:

Base of a pyramid which has four triangular sides is four sided.

If pyramid contains seven layers of oranges then the layer at the bottom will have 7 oranges.

Since base is a square then other side of the square base will have the same number of oranges = 7.

Therefore number of oranges at the first layer will be = 7×7

Similarly other layers above this layer will have the same sequence

6×6, 5×5, 4×4, 3×3, 2×2, 1×1

Therefore total number of oranges = 7×7 + 6×6 + 5×5 + 4×4 + 3×3 + 2×2 + 1×1 = 49 + 36 + 25 + 16 + 9 + 4 + 1 = 140

Option C. 140 is the answer.

A grocer stacks oranges in a four-sided pyramid that is 7 layers high. Many oranges are in the pile are C.140

Further explanation

The orange is the fruit of the citrus species Citrus and sinensis in the family Rutaceae, native to China. Orange is also called sweet orange, to distinguish it from the related Citrus and aurantium, referred to as bitter orange.

The proper name of four-sided pyramid is a "tetrahedron". The tetrahedron has the extra interesting property of having all four triangular sides congruent

1st Layer: The 1st layer contains only 1 orange so it has only 1 orange

2nd layer: The 2nd layer has total 4 oranges. Calculation:   2*2=4

3rd layer: The 3rd layer has total 9 oranges. Calculation: 3 * 3 = 9

4th Layer: The 4th layer has total 16 oranges. Calculation: 4 * 4 = 16.

5th layer: The 5th layer has total 25 oranges. Calculation:  5 * 5 = 25

6th layer: The 6th layer has total 36 oranges. Calculation: 6 * 6 = 36

7th layer: The 7th layer has total 49 oranges. Calculation: 7 * 7 = 49.

Sum of all layers:

1+4+9+16+25+36+49 = 140

The correlation coefficient between two variables is 0.9. how do you describe this value?

Answers

A correlation coefficient of 0.9 shows a strong, almost perfect correlation between the two variables. A positive correlation implies that when one variable increases, the other variable increases together with it. When one variable decreases, the other variable decreases as well.
