Answer:
1) -3/2
Step-by-step explanation:
The common ratio is the amount you multiply by to get to the next number in the sequence. To calculate this you will need to divide the term by its preceding term.
For example (3/4) / (-1/2)
When dividing by fractions you should apply KCF (Keep Change Flip), so you will end up with (3/4) x (-2/1) = -3/2
Check this by doing the next term (-9/8) / (3/4)
When dividing by fractions you should apply KCF (Keep Change Flip), so you will end up with (-9/8) x (4/3) = -3/2

Answer:
36
Step-by-step explanation:
its a square so all sides are equal so do 6 times 6
Answer: 36 cm squared
Step-by-step explanation:
first, we know squares have all equal sides, which means the square has 6cm for each side
we then multiply the base x height which equals 36
finally, since we are finding area, we put a “squared” symbol, or the word “squared”
A cylinder has a base radius of 8ft and a height of 17ft. What is its volume in cubic ft, to the nearest tenths place?
Answers
Answer:
Step-by-step explanation:
Volume = πr²h = π·8²·17 = 1088π ≅ 3,418.1 ft³
Since this cylinder has a radius of 8 feet, its volume is equal to 3,418.5 cubic feet.
Given the following data:
Radius of cylinder = 8 feet.
Height of cylinder = 17 feet.
How to calculate the volume?Mathematically, the volume of a cylinder is given by this formula:
V = πr²h
Where:
h is the height.r is the radius.Substituting the given parameters into the formula, we have;
V = 3.142 × 8² × 17
V = 3.142 × 64 × 17
V = 3,418.5 cubic ft.

Consider random samples of size 80 drawn from population A with proportion 0.48 and random samples of size 66 drawn from population B with proportion 0.13 . (a) Find the standard error of the distribution of differences in sample proportions, . Round your answer for the standard error to three decimal places. standard error
Answers
Answer:
Standard error = 0.070
Step-by-step explanation:
Formula for the standard error of the distribution of differences in sample proportions is;
σ_(A - B) = √((p_a^(1 - p_a^)/n_a) + (p_b^(1 - p_b^)/n_b))
We are given;
p_a^ = 0.48
n_a = 80
p_b^ = 0.13
n_b = 66
Thus;
σ_(A - B) = √((0.48(1 - 0.48)/80) + (0.14(1 - 0.13)/66))
σ_(A - B) = √0.00496545455
σ_(A - B) = 0.070

Anthony buys a guitar for $80. What is the final price he pays after an 8% sales tax?
Answers
Answer:
$86.4
Step-by-step explanation:
You already know that Anthony spent $80 on a guitar and has to pay 8% sales tax so you have to find 8% of $80 and add it to $80 because that is how much he has to pay. 8% of 80=6.4. 6.4+80=86.4 so that is how you get your answer.

3. explain what test will be used and why?
Answers
Answer:
1. H0: u = 500
2. H1: u <500
3. One sample t test
Step-by-step explanation:
1. The null hypothesis in this question would be
H0: u = 500
2. The alternative hypothesis would be
H1: u < 500
3. The test that we are going to be using is the one sample t test. This test is used to test hypothesis. It would make a comparison of h0 to the mean of the sample. Now we are using this here because the sample standard deviation was given
An equilateral triangle has a side length of 1.4x + 2 inches

a side length of 0.5x + 2 inches. The perimeters are equal. What is the side length
of the triangle? What is the side length of the hexagon? Show your work.
op
SOLUTION
Answers
Answer:
The Perimeter of an equilateral triangle = 1.4x+2+1.4x+2+1.4x+2
= 4.2x+6
The Perimeter of a regular hexagon = 0.5x+2+0.5x+2+0.5x+2+0.5x+2+0.5x+2+0.5x+2
= 3x+12
Given that the perimeters are equal
4.2x+6 = 3x+12
4.2x - 3x = 12-6
1.2x = 6
x = 6/1.2
x=5
The side length of the triangle = 1.4x+2
= 1.4 (5) +2
= 9 inches
The side length of hexagon = 0.5x+2
= 0.5(5) +2
= 4.5inches
