Answer:

D is (-3,-7)

E is (4,-7)

F is (4,0)

G is (-3,0)

Step-by-step explanation:

basically translation to the right is addition to the x axis which is the first number in (-7,0) the x axis would be the -7 translation to the left would be subtracting the x axis.

Answer:

D' = (-7,-3)

E' = (4,-7)

F' = (0,4)

G' = (-3,0)

Sorry if these are wrong! They might be flipped around... I'm not sure because I'm not very good at these

18 is ( blank ) % of 30

meriva

Make an equation.

'is' is an equal sign

The blank can be 'x'

'of' = multiplication

18 = x * 30

Multiply:

18 = 30x

Divide 30 to both sides:

x = 0.6

Multiply by 100:

0.6 * 100 = 60%

1. find the area of the two triangles, including the shaded section. the formula for this is a=1/2bh

the height and base are both 24 inches. this is because you add the 10 from the side of the square to the 14 that is given

so:

a=1/2(24)(24)
a=(12)(24)
a=288 sq. inches

since there are two triangles, you would multiply the area by 2

a=2(288)
a=576 sq. inches

now, since you only need the unshaded section, you have to take away the shaded section, which is a square. to do this, you must calculate the area of the square and take it away from the area of both triangles.

a=576-(lw)
a=576- (10)(10)
a=576-100
a=476 sq. inches

that is your answer

Can someone help with this please?

Norma-Jean [14]

Answer:

n=11

Step-by-step explanation:

By inspection,we see that an output is obtained by subtracting 3 from an input and the next consecutive output will follow a pattern of a difference of odd numbers that is 9+5=14

so n=14 and 14-3=11

If Greg Mills is paid 12¢ per unit and produces 170, 165, 149, 157, and 181 units in the 5 days of one week, what is his pay?

Leya [2.2K]

get the total units made:

170 + 165 + 149 + 157 + 181 = 822 units.

Multiply by pay:

822 x 0.12 = $98.64

A textbook company states that the average time a student needs to take a quiz from its book is 30 minutes with a standard devia

faltersainse [42]

Answer:

We conclude that her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company states.

Step-by-step explanation:

We are given;

Population mean; μ = 30 minutes

Population standard deviation; σ = 3 minutes

Sample size; n = 10

Sample mean; x¯ = 25

Significance level = 5% = 0.05

Let's define the hypotheses;

Null hypothesis; H0: μ = 30

Alternative hypothesis: Ha: μ ≠ 30

Let's find the test statistic;

z = (x¯ - μ)/(σ/√n)

z = (25 - 30)/(3/√10)

z = -5.27

From online p-value from z-score calculator attached using, z = -5.27, significance level = 0.05, two tailed hypothesis, we have;

p < 0.00001

This is less than the significance level, and so we will reject the null hypothesis and conclude that Her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated.
