Answer:
a) x+3=19
Step-by-step explanation:
a)
x is the age of Ronald , Collin is three years older than Ronald , so if we add up x(Ronald's age) and 3(the difference between both of their ages), we would get Collin's age(19) . That is the explanation for this equation.
b)
x+3=19
x=19-3
x=16
thus , x is 16 , in other words , Ronald's age is 16.

Answer:
e = 10Step-by-step explanation:
In this question we are provided with an equation that is 9e + 4 = -5e + 14 + 13e . And we are asked to find the value of e .
Solution : -
\( \longrightarrow \qquad \: 9e + 4 = {-5e} + 14 + { 13e}\)
Step 1 : As there are like terms in right side . So we are solving them and get :
\( \longrightarrow \qquad \: 9e + 4 = 14 + 8e\)
Step 2 : Subtracting 4 on both sides :
\( \longrightarrow \qquad \: 9e + \cancel{4 }- \cancel{4 }= 14 + 8e - 4\)
Now , cancelling 4 with -4 and subtracting 4 from 14 :
\(\longrightarrow \qquad \: 9e = 10 + 8e\)
Step 3 : Subtracting 8e on both sides :
\( \longrightarrow \qquad \: {9e } - {8e } =10 + \cancel{ 8e} - \cancel{ 8e}\)
On further calculating , we get :
\(\longrightarrow \qquad \: \underline{\boxed{\bold{ \frak{{e = 10}}}}}\)
Therefore , value of e is equal to 10.Verifying : -
We are verifying our answer by substituting value of e in given equation. So ,
9e + 4 = -5e + 14 + 13e9 (10) + 4 = -5 (10) + 14 + 13 (10)90 + 4 = -50 + 14 + 13094 = -50 + 14494 = 94L.H.S = R.H.SHence, Verified.Therefore, our value for e is correct .

Answers
If the standard deviation of a set of data is 6, then the value of variance is 36
The formula for determining variance is variance = √Standard deviation
Variance of a set of data is equal to square of the standard deviation.
If the standard deviation of a set of data is 6 then we get variance by putting the value of standard deviation in the formula
variance = √Standard deviation
Take square root on both sides
Standard deviation² = 6²
Standard deviation= 36
Hence, standard deviation of a set of data is 6, then the value of variance is 36

The probability that the sum of the two dice is 10 is 1/20 or 0.05.
What is the probability?The probability that the sum of the two dice is 10 is determined as follows:
Outcomes:
Ten-sided die outcomes: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Four-sided die outcomes: 1, 2, 3, 4
The possible sums of 10:
(1, 9)
(2, 8)
(3, 7)
(4, 6)
(5, 5)
For the ten-sided die, there are 10 possible outcomes, so the probability of each outcome is 1/10.
For the four-sided die, there are 4 possible outcomes, so the probability of each outcome is 1/4.
The probability of each pair
(1/10) * (1/10) = 1/100
(1/10) * (1/10) = 1/100
(1/10) * (1/10) = 1/100
(1/10) * (1/10) = 1/100
(1/10) * (1/10) = 1/100
The probability of the sum of 10 will be:

projectile is launched straight up in the air. Its height (in feet) t seconds after launch is given by the function ft)162+432t + 4. Find its average velocity from 1.2 seconds to 13 seconds. Its average velocity is feet per second. If necessary, round to two decimal places.
Answers
The average velocity of the projectile from 1.2 seconds to 13 seconds is approximately 419.40 feet per second.
To find the average velocity of the projectile, we need to calculate the change in height over the given time interval and divide it by the duration. The height of the projectile at time t is given by the function f(t) = 162 + 432t + 4.
First, we need to find the height at the initial time, t = 1.2 seconds, by substituting t = 1.2 into the function: f(1.2) = 162 + 432(1.2) + 4 = 622.4 feet.
Next, we find the height at the final time, t = 13 seconds, using the same process: f(13) = 162 + 432(13) + 4 = 5882 feet.
The change in height over the time interval from 1.2 seconds to 13 seconds is the difference between the final and initial heights: 5882 - 622.4 = 5259.6 feet.
To calculate the average velocity, we divide the change in height by the duration: 5259.6 / (13 - 1.2) = 419.40 feet per second.
Therefore, the average velocity of the projectile from 1.2 seconds to 13 seconds is approximately 419.40 feet per second.

Calculate the area and circumference of a circle with diameter 8cm
Tell me if the photo below is the answer for this question
Answers
Answer: approximately 25.13 centimeters.
Step-by-step explanation: If the diameter of a circle is 8cm, then the radius is half of that, which is 4cm. We can use this information to calculate the area and circumference of the circle as follows:
Area of circle = π * r^2
= π * 4^2
= π * 16
= 16π
≈ 50.27 cm^2 (rounded to two decimal places)
Circumference of circle = 2π * r
= 2π * 4
= 8π
≈ 25.13 cm (rounded to two decimal places)
Therefore, the area of the circle is approximately 50.27 square centimeters and the circumference is approximately 25.13 centimeters.

Answers
If the marginal propensity to consume(mpc) = 4/5 then the government purchases multiplier is 5. Therefore, the answer is (d) 5.
What is the marginal propensity to consume(mpc)?The marginal propensity to consume (MPC) is the fraction of each additional unit of income that is spent on consumption. In other words, it is the change in consumption that results from a one-unit change in income.
What is a government purchase multiplier?The government purchases multiplier is a measure of the impact that changes in government purchases of goods and services have on the overall economy. It is the ratio of the change in the equilibrium level of real GDP to the change in government purchases.
According to the given informationThe government purchases multiplier (K) is calculated using the formula:
K = 1 / (1 - MPC)
where MPC represents the marginal propensity to consume.
In this case, the MPC is given as 4/5, so we can substitute this value into the formula:
K = 1 / (1 - 4/5)
= 1 / (1/5)
= 5

Let A, B and C are events in a sample space while A and B are disjoint events. We know P ( A ) = 2 P ( B ) , P ( C | A ) = 2 / 7 , P ( C | B ) = 4 / 7. What is P ( C | ( A ∪ B ) ) ?
Answers
Answer: P ( C | ( A ∪ B ) ) = 8 / 21
Since A and B are disjoint events, we can use the formula:
P ( A ∪ B ) = P ( A ) + P ( B )
And we are given that P ( A ) = 2 P ( B ), so we can substitute this into the formula:
P ( A ∪ B ) = 2 P ( B ) + P ( B ) = 3 P ( B )
Now, we can use the formula for conditional probability:
P ( C | ( A ∪ B ) ) = P ( C ∩ ( A ∪ B ) ) / P ( A ∪ B )
We can expand the numerator using the distributive property:
P ( C ∩ ( A ∪ B ) ) = P ( ( C ∩ A ) ∪ ( C ∩ B ) )
And we can use the formula for conditional probability to rewrite this:
P ( ( C ∩ A ) ∪ ( C ∩ B ) ) = P ( C | A ) P ( A ) + P ( C | B ) P ( B )
Substituting in the given values:
P ( ( C ∩ A ) ∪ ( C ∩ B ) ) = ( 2 / 7 ) ( 2 P ( B ) ) + ( 4 / 7 ) ( P ( B ) ) = ( 8 / 7 ) P ( B )
Now we can substitute this back into the formula for P ( C | ( A ∪ B ) ):
P ( C | ( A ∪ B ) ) = ( 8 / 7 ) P ( B ) / ( 3 P ( B ) ) = 8 / 21
So the answer is:
P ( C | ( A ∪ B ) ) = 8 / 21

The following linear regression model can be used to predict ticket sales at a popular water park.
Ticket sales per hour = -631.25 + 11.25(current temperature in degrees F).
In this context, does the intercept have a reasonable interpretation?
Answers
No, at 0°F the ticket sales would be -631.25 and it is not reasonable (or possible) to have negative ticket sales in a linear regression model for predicting ticket sales.
In the statistics, the concept of regression analysis is useful for creating a predictive model that predicts the value of a target or dependent variable using all the controlling independent or explanatory variables. Depending on the number of independent variables, regression can be called simple regression or multiple regression. We have a linear regression model that predicts ticket sales for popular water parks.
The regression line equion in this model is written as -631.25 + 11.25 (current temperature in degree F). Comparing above equation with y = a + bx, here, the interaction in the equation above means that hourly ticket sales will be -631.25 when the current temperature (in degrees Fahrenheit) is 0. This does not make sense because hourly ticket sales can be at least 0 but never a negative number. So, it is not reasonable interpretation.

how many 2/3 cups can go into 9 cups
Answers
Hello there! :D
Today we're gonna learn some math, whoopie!
Alright, so we want to know how many 2/3 cups can go into 9 cups!
Firstly, I want to turn 9 cups into a fraction with the denominator of 3.
Let me do it all fancy for you:
\(9=\frac{x}{3}\)
We know we want the denominator to be three, now we just need to do the opposite action (multiplication) to the other side to find what "x" is!
\(9*3= \frac{x}{3}*3\)
If you have trouble understanding that step, let me know!
\(x=27\)
Enter that into the fraction and we have:
\(\frac{27}{3}\)
Notice that 27 is not an even number!
Now, we can the numerator of 27/3s and divide it by the numerator of 2/3s.
\(27/2=13.5\)
This is not a whole answer, but the question is asking how many 2/3 cups can go into nine cups. Half of a 2/3 cup does not equal a 2/3 cup, so the answer would be 13 cups.
I hope this helps you can you have a wonderful day,
Kai xx
The number of 2/3 cups that can go into 9 cups is \(13\frac{1}{2}\)
Total number of cups = 9
The number of 2/3 cups we can get from 9 cups = x
To get the number of 2/3 cups in 9 cups, we will divide 9 by 2/3
Number of 2/3 cups in 9 cups = 9 ÷ 2/3
Number of cups in 9 cups = 9 x 3/2
x = 27/2
x = 13.5
The number of 2/3 cups that can go into 9 cups is \(13\frac{1}{2}\)
