What is the y-intercept of line x = -8?
Answer:
There is no y-intercept.
Step-by-step explanation:
x = -8 has an undefined slope which means that it will never have a y-intercept unless it is x = 0.

Nicholas Has a very large soup pot shaped like a cylinder that has a height of 20 inches and a radius of 6 inches. How much soup can Nicholas’s soup pot hold ?
Answer:
2262 in³
Step-by-step explanation:
Given that:
Height, h = 20 inches
Radius, r = 6 inches
Volume of a cylinder is given as :
V = πr²h
V = π * 6² * 20
V = π * 36 * 20
V = 2261.9467 in³
Hence, Nicholas pot can hold about 2262 in³ of soup

Answer:
m(arc)RST = 154 deg
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
x + 77 + x + 103 = 180
2x + 180 = 180
2x = 0
x = 0
m<RST = x + 77 = 0 + 77 = 77
The measure of an inscribed angle is half the measure of its subtended arc.
m<RST = (1/2)m(arc)RST
77 = (1/2)m(arc)RST
154 = m(arc)RST
m(arc)RST = 154 deg
Income East and West of the Mississippi
For a random sample of households in the US, we record annual household income, whether the location is east or west of the Mississippi River, and number of children. We are interested in determining whether there is a difference in average household income between those east of the Mississippi and those west of the Mississippi.
Incorrect answer iconYour answer is incorrect.
(a) State the null and alternative hypotheses. Your answer should be an expression composed of symbols:
Let group 1 be the households east of the Mississippi River and let group 2 be the households west of the Mississippi River.
(b) What statistic(s) from the sample would we use to estimate the difference?
Let group 1 be the households east of the Mississippi River and let group 2 be the households west of the Mississippi River.
Answer:
H0: μ1 = μ2
H1: μ1 ≠ μ2 ;
xbar1 - xbar2
Step-by-step explanation:
The Null hypothesis should state that there is no difference in average household income between those located east and west of the Mississippi
H0: μ1 = μ2
H1: μ1 ≠ μ2
Statistic from the sample that would be used to estimate difference
Statistic refers to the numerical characteristic derived from the sample.
To estimate the difference in the average household income between those located east and west of the Mississippi, we take the sample mean of the two groups
Group 1, East of Mississippi = xbar 1
Group 2, West of Mississippi River = xbar 2
xbar1 - xbar2
find the degree of the polynomial
Answer:
Step-by-step explanation:
1) 5a - 2b² + 1
Degree of the polynomial = 2
2) 4x²-3x³ + 2x + 12
-3x³ + 4x² + 2x + 12
Degree of the polynomial = 3
To find the degree of the polynomial, arrange it in descending as per the power of the variables.
The highest power of the variable is the degree of the polynomial.

Each marble bag sold by Henry's Marble Company contains 5 purple marbles for every 4 orange marbles. If a bag has 20 orange marbles, how many purple marbles does it contain?
Answer:
25
Step-by-step explanation:
If it's 5 for every 4 and the bag has 20, 4*5 = 20 and you'd have to do that to the 5 as well to get 5*5=25.
Dr. Porterfield a financial counselor guru informed Mr. Halpayne he needs $2,000,000 saved if he intends to retire with his wives (7 of them) and not be homeless in future. Calculate the present value Mr. Halpayne needs if he intends to retire in 20 years provided he invests in a financial plan that pays 5% interest compunded monthly.
9514 1404 393
Answer:
$737,289
Step-by-step explanation:
The future value of an investment P invested at rate r per year compounded monthly for t years is ...
FV = P(1 +r/12)^(12·t)
We want to find P for the given future value, so we can solve for that:
P = FV/(1 +r/12)^(12·t) = FV(1 +r/12)^(-12·t)
P = $2,000,000(1 +.05/12)^(-240) = $737,289
Mr. Halpayne needs a present value of $737,289 to support his retirement.

The number of 5p, 10p, and
20p coins in a jar are in the
ratio 7:4:3. If there are
5p coins are worth 70p
calculate the total value of
the money in the jar.
Answer:
Step-by-step explanation:
70p/5=14
14*4=56*10=560p
14*3=42*20=840p
840+560+70=1470
=1470p or (£14.70)
The total value of money in the jar is 270p.
What is addition?Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.
Given:
The number of 5p, 10p, and 20p coins in a jar are in the ratio 7:4:3.
That means,
Number of 5p coins are 5x, 10p coins are 4x and 20p coins are 3x.
And 5p coins are worth 70p.
That means, x = 70p/5p
x = 14
So,
The total worth of coins are,
= 70p + 80p + 120p
= 270p
Therefore, the worth of the coins are 270p.

Sergei's car was clocked in a quarter mile race at 146.67 miles per hour.
How many feet per second is this to the nearest hundredth if there are 5280 feet in one mile?
A. 29.33 feet per second
B. 35.99 feet per second
C. 215.12 feet per second
D. 733.35 feet per second
E. 860.48 feet per second
Answer:
C. 215.12 feet per second
Step-by-step explanation:
Sergei's car was clocked in a quarter mile race at 146.67 miles per hour.
How many feet per second is this to the nearest hundredth if there are 5280 feet in one mile?
From the above question
1 mile = 5280 feet
1 hour = 60 minutes
1 minutes = 60 seconds
1 hour = 60 × 60 seconds = 3600 seconds
We are to convert 146.67 miles per hour = feet per second
Hence:
146.67 miles /1 ft × 5280 feet/1 miles × 1 hr/3600 seconds
= 146.67 × 5280 feet/3600 seconds
= 774417.6 feet / 3600 seconds
= 215.116 feet per second.
Approximately = 215.12 feet per second

Step-by-step explanation:
I think we are using the order of PEMDAS. We replace the x with 3. If we simplify this expression this is just 3 to the power of 2 multiplied by 2 then subtracted by 7. So 3^2 = 9 then 9 x 2 = 18. Then 18 minus 7 = 11.
