There are 100 students at a college who have taken a course in calculus, 110 who have taken a course in discrete mathematics, an
vesna_86 [32]

Answer:

110 students

Step-by-step explanation:

The number of students who have only taken calculus is given by the number of students who have taken calculus minus the students who have taken both classes:

C =100 -50\\C= 50\ students

The number of students who have only taken discrete mathematics given by the number of students who have taken discrete mathematics minus the students who have taken both classes:

D =110 -50\\C= 60\ students

The number of students that have taken a course in either calculus or discrete mathematics is:

E = C+D = 50+60\\E= 110\ students

4. The diagonal of a rectangle is 13cm. The breadth is 5cm. Find it's length. *​
Citrus2011 [14]

Answer:

The length of the rectangle is

12

c

m

and the area of the rectangle is

60

c

m

2

.

Explanation:

By definition, the angles of a rectangle are right. Therefore, drawing a diagonal creates two congruent right triangles. The diagonal of the rectangle is the hypotenuse of the right triangle. The sides of the rectangle are the legs of the right triangle. We can use the Pythagorean Theorem to find the unknown side of the right triangle, which is also the unknown length of the rectangle.

Recall that the Pythagorean Theorem states that the sun of the squares of the legs of a right triangle is equal to the square of the hypotenuse.

Since the length of the side is a measured distance, the negative root is not a reasonable result. So the length of the rectangle is

The area of a rectangle is given by multiplying the width by the length.

In a multiple regression model involving 44 observations, the following estimated regression equation was obtained. Ŷ = 29 + 18x
icang [17]

Answer: D. .400

Step-by-step explanation:

Given : In a multiple regression model involving 44 observations, the following estimated regression equation was obtained.

\hat{Y}= 29 + 18x_1 + 43x_2 + 87x_3

For this model,

Regression sum of squares =SSR = 600

and Sum of squares due to error =SSE = 400.

Total sum of squares = SST= SSR+SSE

SST= 600+400=1000

The multiple coefficient of determination is given by :-

R^2=1-\dfrac{SSR}{SST}

Substitute values , we get

R^2=1-\dfrac{600}{1000}

R^2=1-0.600=0.400

Thus, the multiple coefficient of determination for the above model is R^2=0.400

Hence, the correct answer is D. .400.
