At a large university, the probability that a student takes calculus and statistics in the same semester is 0.02. The probabilit

Nina [5.8K]

Answer:

The probability that a student is taking calculus given that he or she is taking statistics is = 0.26

Step-by-step explanation:

the probability that a student is taking calculus given that he or she is taking statistics.

Let C = Calculus

S = Statistics

We solve this above Question nursing the formula;

P ( C ∪ S) = P(C) + P ( S ) - P ( C ∩ S)

From the question,

P(C) = 0.10

P( S ) = 0.18

P ( C ∩ S) = 0.02

P ( C ∪ S) = ???

P ( C ∪ S) = 0.10 + 0.18 - 0.02

= 0.28 - 0.02

= 0.26

TIMED QUESTION Which are the roots of the quadratic function f(b) = b2 – 75? Select TWO options.

Setler [38]

Answer:

$b=5\sqrt{3}$ (b = 5 StartRoot 3 EndRoot)

and

$b=-5\sqrt{3}$ (b = Negative 5 StartRoot 3 EndRoot)

Step-by-step explanation:

we have

$f(b)=b^{2}-75$

we know that

The roots of the quadratic function are the values of x when the value of the function is equal to zero

so

For f(b)=0

$b^{2}-75=0$

Solve for b

Adds 75 both sides

$b^{2}=75$

take square root both sides

$b=(+/-)\sqrt{75}$

Simplify

$b=(+/-)5\sqrt{3}$

therefore

$b=5\sqrt{3}$ (b = 5 StartRoot 3 EndRoot)

and

$b=-5\sqrt{3}$ (b = Negative 5 StartRoot 3 EndRoot)

Write an expression to represent the length is 6 feet longer than the width

Ivenika [448]

Step-by-step explanation:

Let l be the length of the room, and w be the width.

If the length is 6 feet longer than twice the width, then we can say l = 2w+6

Knowing that the formula for the perimeter of a rectangle is P = 2l+2w, and knowing that P=144 ft, we can say that 2L + 2w= 144 ft.

To find the dimensions, we plug our value for l into our perimeter equation

This gives us the following equation: 144= 2(2w+6) + 2w, which simplifies to 144=4w+12+2w, which further simplifies to 144= 6w+12

To get w on one side of the equation, we subtract 12 from each side, which gives us 132=6w

Dividing each side by 6, we determine that w= 22 ft.

Plugging this value back into our first equation we see that l= 2(22)+6

So l= 50 ft.

So, the dimensions of the room are as follows: length is 50 ft., width is 22 ft.
