Answer:
The answer is 90;
Step-by-step explanation:
since each variable has a given value, just plug the numbers into the equation.
3(6)5=90
Since there is no d in the equation, don't worry about it:)

The mean income per person in the United States is $41,500, and the distribution of incomes follows a normal distribution. A random sample of 10 residents of Wilmington, Delaware, had a mean of $47,500 with a standard deviation of $10,600. At the .01 level of significance, is that enough evidence to conclude that residents of Wilmington, Delaware, have more income than the national average?

find the attached graph
b) Liner Trend Equation
Where is the linear trend forecast in period t ,
is the intercept of the linear trend time,
is the slope of the linear trend line, t is the time period
now computing the slope and intercept

Final answer:
To find the Mean Squared Error (MSE), you can calculate the difference between the actual and predicted values, square these differences, and find their average. To forecast for a specific year, you can insert the year as the 'x' value into the simple linear regression equation.
Explanation:
The question is asking for the Mean Squared Error (MSE) for a simple linear regression model based on the enrollment data of Jefferson Community College. This involves using the y-intercept (b0) and slope (b1) values provided, and the given data points. You can calculate the MSE by taking the difference between the actual and predicted values (errors), squaring these differences, and then finding the average of these squared differences for the entire dataset.
Then, to forecast for year 10, you use the simple linear regression model equation, y = b0 + b1*x, where y represents the predicted enrollment. So, for year 10, you would insert 10 as your 'x' value into the equation, which results in the forecast value provided which is 19.283.

What is Prism?
A prism is a polyhedron in geometry made up of an n-sidedpolygon basis, a second base that is a rigidly translated copy of the first base, and n additional faces that must all be parallelograms and connect the corresponding sides of the two bases.
We have cuboidal prism which have faces ABFE and EFGH.
To find the point for intersecting we have to find a point or line which is common in both planes.
Here the point E and F are common.
But the plane EF is also common
Thus, the intersecting line is line EF.

Answers
Step-by-step explanation:
given a slope and a point that the line passes through you have 2 options
Option 1: Solve for the equation of the line so you can just use that to graph the line. In this scenario it would be y=(-5/2)x - (20/13)
Option 2: plot the given point and, based on the slope, plot the next point that it crosses. In this case the next point would be (5, 7). Then you can just draw a line using these 2 points.

Answer:
$30 is the price of the original pair of sneakers.
Step-by-step explanation:
You wanna cross multiply so you put :
18. 60
_ = _
x. 100
You multiply 18 the cost of the sneakers by 100 and then divide the product (1800) by 60 and you get $30.
MARK ME AS BRAINLIEST!
Final answer:
The issue pertains to the math topic of discovering a specific percentage of a total. In this case, the $18 John paid for the shorts upon a 60% off sale represents 40% of the original price. Solving the proportion shows us that the original price of the shorts was $45.
Explanation:
The problem is related to the concept of percentages in mathematics, which involves finding a certain percentage of a total value. Here, we know that John paid $18 for the shorts, which represents 40% of the original price because the shorts are on a 60% off sale (100% - 60% = 40%).
To find the original price, we set up a proportion and solve for the original price (symbolized here as x):
40/100 = 18/x
A cross multiplication gives us: 40*x = 1800
To solve for x, we divide both sides by 40: x = 1800/40 = $45
So, the original price of the shorts was $45 before the sale.
