Answer:

−12

Step-by-step explanation:

8 - 5 = -3

-3 x 4 = -12

Answer:

−12

Step-by-step explanation:

8−(5)(4) = -12

Yes, the information could be estimated using a single linear model.

So remember that if a line passes through two points (x₁, y₁) and (x₂, y₂) the slope of that line can be written as:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Here we have 3 points:

(12, 4)

(18, 7)

(36, 15)

Where the first value represents the number of months and the second the number of games sold in thousands.

From these we can form 3 pairs and make 3 slopes, then we can take the mean slope:

[tex]\frac{7 - 4}{18 - 12} = 0.5\\\\\frac{15 - 7}{36 - 18} = 0.44\\ \\\frac{15 - 4}{36 - 12} = 0.46[/tex]

So the mean slope is:

s = (0.5 + 0.44 + 0.46)/3 = 0.467

y = 0.467*x + b

To find the mean value of b, we evaluate the function in the 3 points, and then we take the mean for b.

y  - 0.467*x = b

for each point we have:

4  - 0.467*12 = b = -1.6

7 - 0.467*18 = b = -1.4

15 - 0.467*36 =  -1.8

Taking the mean we get:

(-1.6 - 1.4 - 1.8)/3 = -1.6

So a line that models this can be:

y = 0.467*x - 1.6

to test the line, we can evaluate it in x = 36, we will get:

y = 0.467*36 - 1.6 = 15.212

Comparing, with the actual value, which is 15, we get a percentual error of:

100%*(15.212 - 15)/15 = 1.4%

As you can see, the percentual error with this line is really small, which means that the line is a really good estimation for the relation between the number of months and the number of games sold.

Step-by-step explanation:

Step-by-step explanation:

A factor of a number is any amount that divides into that number exactly , leaving no remainder. Example : 2 is a factor of 12 because 2 goes into 12 six times ( 2 × 6 = 12 ) . This means that 6 is also a factor of 12.

Answer:

5/6 or 0.83 (the 3 is repeated)

Step-by-step explanation:

To reduce this fraction, simply divide the numerator and denominator by 2 (the GCF). So, 1012 = 10÷212÷2 = 5/6. Thus, 1012 is equivalent to 5/6 in the reduced form.

Answer:

The cost after discount would be 11 dollars 73 cents.

Step-by-step explanation:

Given that:

Discount on loyalty card = 8%

Cost of items bought = $12.75

Discount on items = 8% of 12.75

Discount on items = [tex]\frac{8}{100}*12.75[/tex]

Discount on items = 0.08 * 12.75 = $1.02

Total after discount = 12.75 - 1.02 = $11.73

Hence,

The cost after discount would be 11 dollars 73 cents.

Answer:

Area of composite figure = 216 cm²

Hence, option A is correct.

Step-by-step explanation:

The composite figure consists of two figures.

1) Rectangle

2) Right-angled Triangle

We need to determine the area of the composite figure, so we need to find the area of an individual figure.

Determining the area of the rectangle:

Given

Length l = 14 cm

Width w = 12 cm

Using the formula to determine the area of the rectangle:

A = wl

substituting  l = 14 and w = 12

A = (12)(14)

A = 168 cm²

Determining the area of the right-triangle:

Given

Base b = 8 cm

Height h = 12 cm

Using the formula to determine the area of the right-triangle:

A = 1/2 × b × h

A = 1/2 × 8 × 12

A = 4 × 12

A = 48 cm²

Thus, the area of the figure is:

Area of composite figure = Rectangle Area +  Right-triangle Area

                                            = 168 cm² +  48 cm²

                                            = 216 cm²

Therefore,

Area of composite figure = 216 cm²

Hence, option A is correct.
