Answer:

Step-by-step explanation:

Given

(6 + h² - j) ÷ 2 , substitute h = 6 and j = 4 into the parenthesis

= (6 + 6² - 4) ÷ 2

= (6 + 36 - 4) ÷ 2

= 38 ÷ 2

= 19

A tournament is being run between two teams, A and B. This is a 2- tournament meaning that the first team to win 2 games is the

natta225 [31]

Answer:

Step-by-step explanation:

For first game PA = 1/3

For second game PA = 1/3 ( If A is not lost in first game )

= 2/5 (If A is lost in first game )

For conclusion of game in three matches :

If A wins , the probability is

PA , PB , PA = 1/3 X 2/3 X 3/5 = 6/45

PB , PA , PA = 2/3 X 3/5 X 1/3 = 6/45

If B wins

PA, PB, PB = 1/3 X 2/3 X 2/5 = 4/ 45

PB, PA , PB = 2/3 X 3/5 X 2/3 = 4 / 15

Total probability of conclusion of game in 3 matches

= 6/45 +6/45 + 4/45 +4/15 = 28/45

b )

For the game concluding in 2 matches , the probability are as follows

PA,PA = 1/3 X 1/3 = 1/9

PBPB = 2/3 X 2/5 = 4 / 15

Total probability

= 1/9 + 4/15 = 17/45

So PA = 1/9 / 17/45

= 5/17

Anna has saved $37 of her allowance. She needs $50 to register for a skateboard

bulgar [2K]

Answer:

She has $37 out of $50, which can be written as a fraction, 37/50.

In order to be written as a decimal, then we need something like 1/10, which is 0.1, or 5/100, which is .05.

So, 37/50 = ?/100

The easiest way for me to do this problem is to look at our denominators. 50 x 2 = 100, right? This means we need to multiply 37 x 2 to get the missing numerator. 37 x 2 = 74.

Now, how do we write 74/100 as a decimal? .74

Write the fraction as the sum of two fractions with the same denominator

grandymaker [24]

1/4 + 1/4 = 1/2

I got 1/2 because if you add 1/4 and 1/4 you'd get 2/4, and when you simplify 2/4 you'd get 1/2.
