What is the solution set of –|x| = –8?
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
Country Financial, a financial services company, uses surveys of adults age and older to determine if personal financial fitness is changing over time (USA Today, April 4, 2012).

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

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."

write the expression in radical form. 2 4/5
Answer:
[tex]\sqrt[5]{2^4}[/tex]
Step-by-step explanation:
Maybe you want 2^(4/5) in radical form.
The denominator of the fractional power is the index of the root. Either the inside or the outside can be raised to the power of the numerator.
[tex]2^{\frac{4}{5}}=\boxed{\sqrt[5]{2^4}=(\sqrt[5]{2})^4}[/tex]
__
In many cases, it is preferred to keep the power inside the radical symbol.

The ratio of lions to giraffes living in the grasslands was 13 to 2. If there
were 52 lions, how many giraffes lived in the grasslands?
Answer:
8 giraffes
Step-by-step explanation:
52/13 = 4
4 x 2 = 8
Answer:
8 giraffes
Step-by-step explanation:
You can make ratios like this:
13/2=52/?
There is something called the butterfly method where you would multiply the numbers that are diagonal (i.e. 2*52), and divide by what number is left (104/13), and that would give you the answer of the missing number (8).

Step-by-step explanation:Because a positive cancels the negative so it leaves them with a positive
Answer:
Subtracting a negative number from a positive number—when you see the subtraction (minus) sign followed by a negative sign, turn the two signs into a plus sign. Thus, instead of subtracting a negative, you're adding a positive, so you have a simple addition problem.

Which expression us equivalent to this polynomial expression?
(2a - 3b) (2a^2 + 6b^2) + ( 6a^2b + 12ab^2 - 7b^3)
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

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)
What is the Slope of Perpendicular Lines?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)

What is an equation of the line that passes through the point (-1,4) and is parallel
to the line x + y = 4?
Answer:
y = -x + 3
Step-by-step explanation:
Solve x + y = 4 for y
You'll get y= -x+4
The parallel line has the same slope so use this in the point given to find the y intercept. y = -x +3
Write 1.64 as a mixed number in lowest terms.
Answer:
[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
