Answer:

  with respect to transversal n, angles 2 and 10 are "corresponding" angles

Step-by-step explanation:

Angles 2 and 10 are at different intersections. The line common to those intersections is the transversal, line n.

The transversal is line n.

The two angles are on the same side of the transversal, and are on the same side of the line crossing the transversal. Hence, they are "corresponding" angles.

Angles 2 and 10 are "corresponding angles."

Answer:

D. 4a³ + 24ab² - 25b³

Step-by-step explanation:

Simplify the given polynomial expression to find its equivalent as follows:

(2a - 3b)(2a² + 6b²) + (6a²b + 12ab² - 7b³)

2a(2a² + 6b²) -3b(2a² + 6b²) + (6a²b + 12ab² - 7b³)

4a³ + 12ab² - 6a²b - 18b³ + 6a²b + 12ab² - 7b³

Collect like terms

4a³ - 6a²b + 6a²b + 12ab² + 12ab² - 18b³ - 7b³

4a³ + 24ab² - 25b³

Therefore, 4a³ + 24ab² - 25b³ is equivalent to the polynomial expression, (2a - 3b)(2a² + 6b²) + (6a²b + 12ab² - 7b³).

Answer:A- 4a³+24ab²-25b³

Answer:

x = 8 or x = -8

Step-by-step explanation:

Solve for x over the integers:

-abs(x) = -8

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides by -1:

abs(x) = 8

Hint: | Eliminate the absolute value.

Split the equation into two possible cases:

Answer: x = 8 or x = -8

The ordered pairs of the points on a line that is perpedicular to a line with a slope of -4/5 are:

A. (–2, 0) and (2, 5)

E. (2, –1) and (10, 9)

The slopes of the lines that are perpendicular to each other are negative reciprocal to each other, that is, is the slope of one is 4, the slope of the other would be -1/4.

Slope = change in y/change in x

Slope of the line that lie between (–2, 0) and (2, 5):

Slope = (5 - 0)/(2 - (-2)) = 5/4

Slope of the line that lie between (2, –1) and (10, 9):

Slope = (9 -(-1))/(10 - 2) = 10/8 = 5/4

The negative reciprocal of -4/5 is 5/4.

Therefore, the ordered pairs of the points on a line that is perpedicular to a line with a slope of -4/5 are:

A. (–2, 0) and (2, 5)

E. (2, –1) and (10, 9)

Complete question is;

Country Financial, a financial services company, uses surveys of adults age 18 and older to determine if personal financial fitness is changing over time (USA Today, April 4, 2012). In February of 2012, a sample of 1000 adults showed 410 indicating that their financial security was more than fair. In February of 2010, a sample of 900 adults showed 315 indicating that their financial security was more than fair. What is the p value?

Answer:

p-value = 0.006934

Step-by-step explanation:

First of let's define the hypotheses.

Null hypothesis: H0: p1 - p2 = 0

Alternative hypothesis: Ha: p1 - p2 ≠ 0

We are given;

Number of people in 2012 that indicated their financial security was more than fair; x1 = 410

Number of people in 2010 that indicated their financial security was more than fair; x2 = 315

Sample in 2012; n1 = 1000

Sample in 2010; n2 = 900

proportion of people in 2012 that indicated their financial security was more than fair; p1 = x1/n1 = 410/1000 = 0.41

proportion of people in 2010 that indicated their financial security was more than fair; p2 = x2/n2 = 315/900 = 0.35

Now, let's find the z - score with the formula;

z = (p1 - p2)/√[(p1(1 - p1) × (1/n1)) + (p2(1 - p2) × (1/n2))]

Thus;

z = (0.410 - 0.35)/√[(0.41(1 - 0.41) × (1/1000)) + (0.35(1 - 0.35) × (1/900))]

z = 0.06/√0.00049467778

z ≈ 2.7

From online p-value calculator attached using z-value = 2.7; two tailed distribution; significance level = 0.05;

We have; p-value = 0.006934

[tex]1\frac{16}{25}[/tex]

Step-by-step explanation:

So we have the decimal:

[tex]1.64[/tex]

We can rewrite this as:

[tex]=1+0.64[/tex]

0.64 is the same as 64/100. So:

[tex]=1+\frac{64}{100}[/tex]

We can divide both layers by 4. This gives us:

[tex]=1+\frac{64/4}{100/4}[/tex]

Divide:

[tex]=1+\frac{16}{25}[/tex]

So, as a mixed fraction, this is:

[tex]1\frac{16}{25}[/tex]

And we're done!

Answer:

1 16/25

Step-by-step explanation:

You write 1.64 as 1 64/100

Then you simplify it to 1 16/25

11/20

Step-by-step explanation:

3/20 + 2/5 = 11/20

Answer:

v in (-oo:+oo)

1.13/64 = (11/8)*v // - (11/8)*v

1.13/64-((11/8)*v) = 0

(-11/8)*v+1.13/64 = 0

0.01765625-11/8*v = 0 // - 0.01765625

-11/8*v = -0.01765625 // : -11/8

v = -0.01765625/(-11/8)

v = 0.01284091

v = 0.01284091

Step-by-step explanation:

1 13/64 = 11/8x

Rewrite the left side as an improper fraction:

77/64 = 11/8x

Divide both sides by 11/8

77/11 = 7

64/8 = 8

X = 7/8
