Answer:

Hence, option 3 is correct.

Step-by-step explanation:

Given,

Side of a square = 8 units

Also,

The shaded triangles base = Height of the triangle = Side of the square = 8 units.

(Sides of a square are always same)

Hence, area of the shaded triangle will be,

[tex] = \frac{1}{2} . \: base \: . \: height[/tex]

[tex] = \frac{1}{2} . \: 8 \: . \: 8 \: (ans)[/tex]

Answer:

1 [tex]\frac{3}{4}[/tex] cups

Step-by-step explanation:

Convert the numbers to decimals, then subtract the amount needed from the amount in the juice container:

4.25 - 2.5

= 1.75

This is equivalent to the fraction 1[tex]\frac{3}{4}[/tex]

So, after Yupin makes the punch, there will be 1[tex]\frac{3}{4}[/tex] cups of guava juice left in the container

Answer:

Step-by-step explanation:

The interest rate is about 7% per year.

Simple interest is the amount of interest charged on a specific principal amount at a specific interest rate. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.

We can use the formula for simple interest to find the annual interest rate:

I = P * r * t

where I is the interest, P is the principal (the amount borrowed or invested), r is the annual interest rate as a decimal, and t is the time in years.

Plugging in the given values, we have:

164.50 = 940 * r * 2.5

Dividing both sides by 940 * 2.5, we get:

r = 164.50 / (940 * 2.5)

r ≈ 0.07

Multiplying by 100 to convert to a percentage, we get:

r ≈ 7%

Therefore, the annual interest rate is approximately 7%.

Answer:A) the answer is 0.28 in meters or 28 in cm

B) the anwser is 0.48 in meters and 48 in cm

Step-by-step explanation:

P=8+6+8+6 = 26cm

A=8x6=48

Answer:

1. the company C used 10 drivers2.      6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10  (6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4  = 16/10 = 1 6/103. The groups that had the most deliveries where group A and B4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4

Step-by-step explanation:

The mean absolute deviation of company C's data is 2.

A dot plot, also known as a strip plot or dot chart, is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis. These types of charts are used to graphically depict certain data trends or groupings.

The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.

Number of drivers used by company C in its sample = 10

Mean absolute deviation for company C's data = 2

Company B has the greatest mean number of deliveries.

The mean deliveries of company B is 4 times MAD of company A.

We are given the sum of each point from the mean. It is 20.

Mean absolute deviation of company C  = 20/10 = 2.

Mean A = 6

Mean B = 14

Mean B - Mean A = 8 = 4×2 = 4 times MAD (since MAD =2 for both companies).

Therefore, the mean absolute deviation of company C's data is 2.

Answer:

No, they are not equivalent

Step-by-step explanation:

[tex]\frac{-2}{3}(12b - 6 + 9b - 18) = \frac{-2}{3}(12b + 9b - 6 - 18)\\\\=\frac{-2}{3}(21b - 24)\\\\ = \frac{-2}{3}*21b -24*\frac{-2}{3}\\\\= -2*7b + 8*2\\\\= 2( -7b + 8)[/tex]

Answer:

This is NOT equivalent to 2b(b + 8).

Step-by-step explanation:

Start with -2/3(12b - 6 + 9b - 18).  Simplify this.  First, combine the like terms inside the set of parentheses:

(-2/3)(21b - 24)

Simplify this by applying the distributation property of multiplication:

-14b + 16

Finally, factor out 2:  2(-7b + 8)

This is NOT equivalent to 2b(b + 8).
