Which equation has a graph parallel to the graph of 9.x + 3y = -22?
Answer:
y = -3x - 8.3
Step-by-step explanation:
You need to rearrange 9x + 3y = -22 in the form y = mx+c.
9x+3y = -22
3y = -9x - 22
y = -3x - 7.3
As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.
Final answer : y = -3x - 8.3
The equation of the line having the parallel graph will be;
⇒ Y = -3x + 8
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
Given that;
The equation of line is,
⇒ 9x + 3y = - 22
Now,
Since, The general form of the equation of the line:-
⇒ y = mx + b
Where, m = slope
b = y-intercept
And, Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
For the parallel lines, the slope of the two lines is always equal.
Here, The given equation will be written as,
⇒ 9x + 3y = -22
⇒ 3y = -9x -22
⇒ y = -3x - (22/3)
Let the equation of the graph is,
⇒ Y = -3x + 8
It has slope = m = dy/dx = - 3
Therefore, the equation of the line having the parallel graph is Y = -3x + 8.

A study was commissioned to find the mean weight of the residents in certain town.
The study found the mean weight to be 187 pounds with a margin of error of 3
pounds. Which of the following is not a reasonable value for the true mean weight of
the residents of the town?
The value that is not reasonable for the true mean weight of the residents of the town is 193 pounds
Given that the mean weight is 187 pounds with a margin of error of 3 pounds, we can construct the interval as follows:
Mean weight - Margin of error = 187 - 3 = 184 pounds
Mean weight + Margin of error = 187 + 3 = 190 pounds
So, the reasonable range for the true mean weight of the residents of the town is between 184 and 190 pounds.
Now, let's evaluate the options to identify the value that falls outside this reasonable range:
A. 170 pounds - This value falls below the lower limit of the reasonable range (184 pounds). Therefore, it is not a reasonable value for the true mean weight.
B. 188 pounds - This value falls within the reasonable range of 184 to 190 pounds. It is a reasonable value.
C. 193 pounds - This value falls above the upper limit of the reasonable range (190 pounds). Therefore, it is not a reasonable value for the true mean weight.
D. 186 pounds - This value falls within the reasonable range of 184 to 190 pounds. It is a reasonable value.
E. 182 pounds - This value falls below the lower limit of the reasonable range (184 pounds). Therefore, it is not a reasonable value for the true mean weight.
From the options provided, the value that is not reasonable for the true mean weight of the residents of the town is 193 pounds.

The number of years it will take for both accounts to have the same amount of money is about 17 years
What is an exponential equation?An exponential equation is an equation of the form; y = a·bˣ, where the input variable, x is an exponent.
The equation for calculating the amount in each bank, based on the details are;
TCF Bank;
Amount invested = $1,000
Amount added each year = 100·x
The TCF Bank Equation is; y = 100·x + 1000Well Fargo Bank Equation
The percentage of the amount earned as interest each year = 6% = 0.06
The exponential equation for compound interest amount is; y = 1000·(1 + 0.06)ˣ
Therefore; y = 1000·(1.06)ˣ
The Well Fargo Bank Equation is; y = 1000·(1.06)ˣWhen the amount in the two accounts have the same amount of money, we get;
1000·(1.06)ˣ = 100·x + 1000
Therefore; (1.06)ˣ = (100·x + 1000)/1000 = 0.1·x + 1
(1.06)ˣ = 0.1·x + 1

Greg is installing a tile floor in a room that is 10 feet long by 15 feet wide. He will use 1-foot square tiles. He has two different types of tile: plain and hand-painted. Plain tiles cost $0.79 per tile. Hand-painted tiles cost $5.00 per tile. What is the maximum number of hand-painted tiles that Greg can use to keep the total cost under $200?
Answer:
The maximum number of hand-painted tiles that Greg can use to keep the total cost under $ 200 is 19.
Step-by-step explanation:
Since Greg is installing a tile floor in a room that is 10 feet long by 15 feet wide, and he will use 1-foot square tiles, and he has two different types of tile: plain and hand-painted, and plain tiles cost $ 0.79 per tile, while hand-painted tiles cost $ 5.00 per tile, to determine what is the maximum number of hand-painted tiles that Greg can use to keep the total cost under $ 200, the following calculation must be performed:
10 x 15 = 150
150 x 0.79 + 0 x 5 = 118.5
130 x 0.79 + 20 x 5 = 202.7
131 x 0.79 + 19 x 5 = 198.49
Therefore, the maximum number of hand-painted tiles that Greg can use to keep the total cost under $ 200 is 19.
How much space will a cylindrical water tank occupy if its height is 100 cm and its diameter is 30
find the volume
Answer:
volume of a cylindrical water tank = 70,650cm³
Step-by-step explanation:
volume of cylinder, V = πr²h
where π = 3.14
h = 100cm
r = ?
given is diameter = 30cm
r = d/2 = 30/2 = 15cm
substituting the values in the formula,
V = 3.14 * 15² * 100
= 3.14 * 225 * 100
= 70,650cm³
Answer:
How much space it would take up: 706.86 square centimeters of floor space and extend vertically to a height of 100 cm
Volume: 706,500 cm³
Step-by-step explanation:
How much space it would take up:
To determine the space occupied by a cylindrical water tank in a room, we need to consider its dimensions and the area it covers on the floor.
The diameter of the tank is given as 30 cm, which means the radius is half of that, 15 cm.
To calculate the space it occupies on the floor, we need to find the area of the circular base. The formula for the area of a circle is A = πr², where A is the area and r is the radius.
A = π(15 cm)²
A = π(225 cm²)
A ≈ 706.86 cm²
So, the circular base of the tank occupies approximately 706.86 square centimeters of floor space.
The height of the tank is given as 100 cm, which represents the vertical space it occupies in the room.
Therefore, the cylindrical water tank would take up 706.86 square centimeters of floor space and extend vertically to a height of 100 cm in the room.
Volume:
To calculate the volume of a cylindrical water tank, we can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height.
First, we need to find the radius by dividing the diameter by 2:
Radius = 30 cm / 2 = 15 cm
Now we can calculate the volume:
V = π(15 cm)²(100 cm)
V = 3.14 * 225 cm² * 100 cm
V = 706,500 cm³
Therefore, the cylindrical water tank will occupy a volume of 706,500 cm³ or 706.5 liters.
Answer within 2 minutes
Answer:
blue option
Step-by-step explanation:
4 times as many as the other
total of 1550 yards
x and y represent the individual players' yards rushed
y+x=1550
or
x+y=1500
and
y=4x
or
x=4y
the option we have is x+y=1500 and y=4x, which is option blue
Let x and y be the number of yards each team runned. In a way that y>x.
Combined they runned 1550 yards, so:
\(x+y=1550\)
And one of them is 4 times higher than the other, so:
\(x = 4\cdot y\)
So the system will be:
\(\begin{cases}x+y=1550 \\y = 4x \\\end{cases}\)

The average age for retirement in the US is heavily skewed left with a mean of 62 years of age and a standard deviation of 5.42 years.
Explain why you cannot use a normal model to determine the probability that a randomly chosen new retiree is less than 60 yeatrs of age.
We cannot determine the probability that a newly selected adult is older than 62 because there is not much to do with the distribution other than the sample and standard deviation and skewness of the distribution.
Most US workers retire at 64, but data show that the average age varies by state. For example, the average retirement age in Washington, DC is about 67, while many states such as Iowa, Kansas, Maryland, Vermont, and Texas have the average retirement age of 65. 61 in Alabama, Kentucky and Michigan or Alaska and West Virginia.
The average probability of retirement age has increased in recent years. In 1986, the average retirement age was 62 for men and 57 for women. From 2016, the average retirement age increased to 65 for men and 63 for women. Changes in SSI, reductions in workplace pensions, and even longer life expectancy can cause many to delay retirement for at least a few years.
Plus, with Social Security benefits averaging just $1,503 per month and declining pensions, seniors are expected to find their retirement savings and maximize their income spending. It will also cause them to postpone their holidays.

During the 2013 Major League Baseball season, the St. Louis Cardinals averaged 41,602 fans per home game. Suppose attendance during the season follows the normal probability distribution with a standard deviation of 9,440 per game. 95% of the attendance around the average is between (3,282", 22,722", 3,842",18,002"] and [69,922", 65,202", 60,482,", 79,362"] .
Answer:
About "95% of the attendance around the average is between" 22722 and 60482.
Step-by-step explanation:
The key to answering this question is the application of the 68-95-99.7 rule. It is a rule that "tells us" that data that follow a normal distribution approximately:
68% (68.27% to be more precise) of the observations are one standard deviation above and below the mean. We can express this mathematically as:\( \\ P(\mu - 1\sigma \leq X \leq \mu + 1\sigma) = 0.6827 \approx 0.68\) [1].
95% (95.45%) of the data are two standard deviations above and below the mean.\( \\ P(\mu - 2\sigma \leq X \leq \mu + 2\sigma) = 0.9545 \approx 0.95\) [2].
99.7% (99.73%) of the data are three standard deviations above and below the mean.\( \\ P(\mu - 3\sigma \leq X \leq \mu + 3\sigma) = 0.9973 \approx 99.7 \) [3].
The two parameters that characterized the normal distribution are the mean, \( \\ \mu\), and the standard deviation, \( \\ \sigma\).
In this case, we have:
\( \\ \mu = 41602\).\( \\ \sigma = 9440\).According to the 68-95-99.7 rule above explained, we know that the "95% of the attendance around the average" is two standard deviations, \( \\ \sigma\), above and below the mean, \( \\ \mu\).
Then, using [2], we have:
\( \\ P(\mu - 2\sigma \leq X \leq \mu + 2\sigma) = 0.9545 \approx 0.95\) [2].
\( \\ P(41602 - 2*9440 \leq X \leq 41602 + 2*9440) = 0.9545 \approx 0.95\).
\( \\ P(41602 - 18880 \leq X \leq 41602 + 18880) = 0.9545 \approx 0.95\).
\( \\ P(22722 \leq X \leq 60482) = 0.9545 \approx 0.95\).
Therefore, about "95% of the attendance around the average is between" 22722 and 60482.
Notice that we approximate the values using the 68-95-99.7 rule, which is a good approximation and sufficient for practical uses. However, if we want to know exactly the 95% of the attendance around the average, we can calculate it using the formula for z-score (which, roughly speaking, "tell us" the distance from the mean in standard deviations units of a normally distributed value):
\( \\ z = \frac{x - \mu}{\sigma}\) [4]
A positive value of z indicates that x is above the mean and a negative that x is below the mean.
Since the normal distribution is symmetrical around the mean, we can divide the 95% of probability in two equal parts. One above the mean, \( \\ \frac{0.95}{2} = 0.475\), and the other below the mean \( \\ \frac{0.95}{2} = 0.475\)
If we consult the cumulative standard normal table from the mean (0 to Z), the value for z, in this case, is \( \\ z = 1.96\), because for a probability of 0.475, the value of z = 1.96. Remember that the standard normal normal distribution has a \( \\ \mu = 0\) and \( \\ \sigma = 1\). That is why the interval is from 0 (mean) to the value of Z.
Therefore, solving [4] for x, for an exactly value of 95% of the attendance around the average is between:
Upper value
The value is above the mean:
\( \\ 1.96 = \frac{x - 41602}{9440}\)
\( \\ (1.96 * 9440) + 41602 = x\)
\( \\ x = (1.96 * 9440) + 41602\)
\( \\ x = 60104.40 \approx 60104\)
Lower value
The value is below the mean:
\( \\ -1.96 = \frac{x - 41602}{9440}\)
\( \\ x = (-1.96 * 9440) + 41602\)
\( \\ x = 23099.60 \approx 23100\)
Or an exactly value of 95% of the attendance around the average is between 23100 and 60104. Notice that the question gives us options using the 68-95-99.7 rule, that is, 22722 and 60482, which are also valid (with less precision).
The below graphic shows the previous result (which is very similar to that obtained using the 68-95-99.7 rule.)
