According to the given data, the operating altitude of a glider is 5000 ft. Next highest is that of an airship, at 3000 ft. Next is a sailboat (water level, or 0 ft).
Last is a submarine, 1500 feet below the surface.
{5000, 3000, 0, -1500} (answer)
Answer: (50,-20)
Step-by-step explanation:
Point B is (100,0).
Point A is (0,-40).
To find C you need the midpoint of both A and B, which means you add both coordinate x and coordinate y together to find the middle of both.
Midpoint of x coordinates:
100+0= 100
100÷2= 50
Midpoint of y coordinates:
0+(-40)= -40
-40÷2= -20
Therefore, point C is (50,-20)
Answer: C. Substitute a value of x into the equation of a regression line and solve for y
Step-by-step explanation: To predict y values using equation of the regression line, a given value of x is substituted into the equation as there are only two unknowns in the whole regression equation, which are the x value ( independent variable) and the y value (the dependent or predicted variable).
The regression equation is usually of the form:
y = mx + c (linear regression)
Where y = predicted or dependent variable
m = slope or gradient of the regression line
x = independent variable
c = intercept of the line (where it cross the y-axis)
Answer:
The mean of of the sample mean of these quality checks is 10 and the standard deviation is 0.7155.
Step-by-step explanation:
To solve this question, we use the central limit theorem.
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , the sample means with size n can be approximated to a normal distribution with mean and standard deviation
In this problem, we have that:
The mean of of the sample mean of these quality checks is 10 and the standard deviation is 0.7155.
