The probability of tossing a coin of getting head is 1/2 because there are two faces in the coin one of them is head

P(h) = 1/2

Since there are two coins will tossing together, then the probability of each coin getting a head is 1/2

We need to getting head in both, then we will multiply the two of them

P(h\text{ and h) =}\frac{1}{2}\times\frac{1}{2}=\frac{1}{4}

Then the probability is 1/4

Which of the following theorems cannot be used to prove two lines are<br> parallel?
mariarad [96]

Answer:

Option H

Step-by-step explanation:

Option F

If two lines are cut by a transversal so that a pair of corresponding angles are congruent, then the lines are parallel.

True.

Option G

If two lines are cut by a transversal so that a pair of alternate exterior angles are congruent, then the lines are parallel.

True

Option H

If two line are cut by a transversal so that a pair of vertical angles are congruent, then the lines are parallel.

Since, vertical angles don't prove the lines cut by a transversal are parallel.

So the statement is False.

Option J

If two lines are are cut by a transversal so that a pair of same side interior angles are supplementary, then the lines are parallel.

True.

Simplify the expression.<br> 16n−16
Alex787 [66]

Answer:

16(n-1)

Step-by-step explanation:

16(n-1) is the simplest form of 16n-16 because you cannot backtrack any farther. To get to 16n-16, you must have 16(n-1) first. When you distribute, you will have 16n and -16. Put those into an equation, you get 16n-16 which is what you have originally.

For what values of​ a, m, and b does the function​ f(x) satisfy the hypotheses of the mean value theorem on the interval [0 comm
igomit [66]

Answer:

a = -5

b = -1

m = -1

Step-by-step explanation:

Piecewise function:

f(x)= -5, x=0

f(x)= −x^2+3x+a, 0<x<2

f(x)= mx + b 2≤x≤3

The mean value theorem is applicable if f(x) is continuous on the entire closed interval [0;3] and differentiable on the entire closed interval [0;3].

To satisfied that at x = 0 :

−x^2+3x+a = -5

Then, a = -5

 

Derivative of −x^2+3x-5 is -2x + 3 and derivative of mx + b is m, at x = 2:

-2(2) + 3 = m

-1 = m

Replacing the functions at x = 2 :

−x^2+3x-5 = -x + b

−(2)^2+3*2-5 = -2 + b

-3 + 2 = b

-1 = b
