Answers

Answer:

36miles

Step-by-step explanation:

Given parameters:

Rate  = 12mph

Time  = 3hr

Unknown:

Distance = ?

Solution:

The given rate amount is the speed. Speed is the distance divided by the time.

It is mathematically expressed as:

         Speed  = [tex]\frac{distance}{time}[/tex]  

    Distance  = Speed x time

    Distance  = 12 x 3  = 36miles

Find the value of X, then find AB and DC.
(opposite sides are congruent)
AB= 3x+8
DC= x+12

Answers

Answer:

X=2, AB=14, DC=14

Step-by-step explanation:

3x+8=x+12

Subtract x from both sides

2x+8=12

Subtract 8 from both sides

2x=4

Divide by 2 on the sides

Answer: x=2

Then replace the x's with (2) and multiply

3(2)+8 and (2)+12

Answer:

Both AB and DC are equal to 14.

Suppose you draw 8 cards out of a well-shuffled deck of 52 cards, and one-by-one with re-placement, consider X as the number of spades that you obtain. Which is the distribution of X?

Answers

Answer:

It is a Binomial experiment with n = 8 and p = 0.25

Step-by-step explanation:

It is given that we draw 8 cards out of the well shuffled deck of 52 cards one by one replacement.

Given :

[tex]$n=8$[/tex]

P (getting a spade) = [tex]$\frac{13}{52}$[/tex]

                               = 0.25

As in the question, we are sampling with the replacement, so the probability of getting a spade in each draw remains the same and the all the draws are independent.

Therefore it is a Binomial experiment with n = 8 and P = 0.25

19 + 11 - 12² ÷ 3 (12 - 9) · 11)) - 7 =


Use PEMDAS for this.

Also it's a made up question

Answers

PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

First, subtract the numbers in the parentheses, then multiply by 11.

(12 - 9) = (3)

3 x 11 = 33

19 + 11 - 12^2 ÷ 3(33) - 7

Now, just multiply 33 by 3, and then square 12 (12 x 12).

19 + 11 - 144 ÷ 99 - 7

Now, you can divide 144 by 99, this is an infinite number, so..

144 ÷ 99 = 1.455

19 + 11 - 1.455 - 7

Finally add, then subtract.

30 - 1.455 - 7

28.545 - 7

The final answer is 21.545.
