Your test scores in one class are 79 and 83. What possible scores can you earn on your next test to have a test average between 81 and 87, inclusive?

Answers

Answer 1

Answer:

83 and 84

Step-by-step explanation:

these numbers will both work because if you make an equation 79+83+x=y, with 87≥y≥81, and plug in these numbers for x, the answers are around 82 which is within the range.

6.833

3.594

+1.369

11.796

round the whole number to get 12

Rounding to the first decimal place, calculate the mean for the following distribution of homicide rates in the 12 metropolitan areas with the lowest homicide rates (homicides per 100,000 population) in the U.S. in 2017.
Mesa, AZ: 4.1 Seattle, WA: 3.8 Portland, OR (tie): 3.4 New York, NY (tie): 3.4 Virginia Beach, VA: 3.3 San Jose, CA: 3.1 El Paso, TX: 2.9 Austin, TX: 2.6 San Diego, CA: 2.4 Suffolk County, Long Island, NY: 2.2 Montgomery County, MD: 2.0 Fairfax, VA: 1.7

Answers

Solution :

Given :

X = homicide rate (homicides per 100,00 population)

n = 12 = metropolitan areas

Area                          X (homicides per 100,000 population)

Mesa, AZ                   4.1

Seattle, WA               3.8

Portland, OR (tie)      3.4

New York, NY(tie)     3.4

Virginia beach, VA   3.3

San Jose, CA           3.1

EI, Paso, TX             2.6

Austin, TX                2.6

San Diago, CA         2.4

Suffolk County         2.2

Montgomery, MD    2.0

Fairfax, VA              1.7

Therefore, the mean of X = [tex]$\bar X = \frac{\sum X_i}{n}$[/tex]

                                           [tex]$=\frac{34.9}{12}$[/tex]

                                          = 2.9

Therefore, the mean of homicide rater in the 12 metropolitan areas is 2.9 homicide per 100,000 population.

What value would make the equation 8x = -72 true?

Answers

Answer:x= -9

Step-by-step explanation: You would dive both sides by 8 and -72 divided by 8 is -9

Answer:-9

Step-by-step explanation:

The answer is -9 because we are solving to get x by itself. Since 8 is being multiplied by x the opposite of multiplication is division. Divide both sides by 8 to get x by itself. -72 divided by 8 is -9 because a negative divided or multiplied by a positive is a negative. To check your work you can do 8 times -9 which equals -72.

Reflect the figure across the y- axis, then state the ordered pairs of the image.

May someone please explain how I would reflect it?

Answers

EXPLANATION:
Reflecting a figure across the y-axis basically means flipping all of the x-values of your coordinates while retaining its y-value.
In other words, flip the signs of x and keep y the exact same for each coordinate.

What is triangle?

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

Here, given that,

In ΔGHI, i = 64 inches, g = 91 inches and ∠H=134°

Now. we know that,

a sinA =b sinB =c sinC

We get,

length of h = 57.4 inch.

hence, The  length of h, to the nearest inch. is 57.4 inch.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

According to the PEMDAS rule, the operation should be performed in the order of the computation or the parentheses, whichever comes first.

The sum of three and five to the third power times five plus one will be written mathematically and will be
