Answer:

no the first is -7 and the 2nd is 7

Answer:

No

Step-by-step explanation:

The absolute value makes anything in it positive. So I-7I is 7. But if there is a negative sign OUTSIDE of the absolute value, then it is negative.

-I-7I is -7

I-(-7)I is 7

Answer:

D (Alicia did 5 more jumping jacks per minute than Melissa.)

Step-by-step explanation:

Alicia's rate is 30 jumping jacks per minute. You can use the formula m=(y2-y1)/(x2-x1) to find the slope/rate. The two points in the table you can use are (1,30) and (2,60). You can plug those coordinates into the slope formula. (60-30)/(2-1)=30/1= 30 jumping jacks per minute.  To find the rate of change/slope for Melissa, you can use the same formula m=(y2-y1)/(x2-x1). The two points you could plug in are (0,0), and (4,100). (100-0)/(4-0)=100/4=25. Melissa does 25 jumping jacks per minute.

The linear regression equation that represents this set of data is given as follows:

y = 1.05x - 10.43.

The estimated homework grade for a student with a test grade of 31 is given as follows:

39.46.

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator.

The points for this problem are given as follows:

(58, 52), (75, 66), (66, 68), (85, 74), (53, 38), (74, 65), (78, 76).

Inserting these points into a calculator, the equation is given as follows:

y = 1.05x - 10.43.

The estimated homework grade for a student with a test grade of 31 is x when y = 31, hence:

31 = 1.05x - 10.43

x = 41.43/1.05

x = 39.46.

How do you figure out if a shape is similar or not using rectangle diagnols?

Assuming that diagnols = diagonal, it is not possible to define a similarity relationship without measuring at least one side.

Answer: 1/9

Step-by-step explanation: We can start the problem by using the concept of unit rate.

We know that the gardener spread 2/3 of a bag of mulch over his 6 vegetable beds. To find the amount of mulch per bed, we can divide the total amount of mulch by the number of beds.

So, the unit rate of mulch per bed is (2/3) / 6 = 1/9 of a bag of mulch.

So, the gardener put 1/9 of a bag of mulch on each vegetable bed.

Answer: 1/9

Step-by-step explanation:

If it was one bag, it would have been 1÷6 and the answer would have been 1/6 for each vegetable bed.

So if we do the same with 2/3, this is (2/3)/6. Let’s try this:

=\(\frac{2}{3}\)÷\(\frac{6}{1}\)
=\(\frac{2}{3}\)×\(\frac{1}{6}\)

=\(\frac{2}{19}\)

=\(\frac{1}{9}\)

Therefore, the gardener put 1/9th of the bag of mulch on each vegetable bed.

Answer:

B; C

Step-by-step explanation:

V = (4/3)*pi*(r^3)

pi = 3.14, r = 4.5

so V = (4/3)(3.14)(4.5^3) which is choice B

Answer:

The volume (V) of a cone can be calculated using the formula: V = (1/3)πr^2h, where r is the radius and h is the height.

Substituting the given values, we get:

V = (1/3) x 3.14 x 9^2 x 16

Calculating this expression gives us:

V = 1810.08 cubic inches

Rounding to the nearest hundredth gives us:

V ≈ 1810.08 cubic inches (rounded to two decimal places)

Therefore, the volume of the cone is approximately 1810.08 cubic inches.

Answer:

1363.04

Step-by-step explanation:

V = (1/3) * 3.14 * 9^2 * 16

Simplifying:

V ≈ 1363.04 cubic inches
