Answer:

1 pizza was left.

Step-by-step explanation:

If they didn't eat 1/2 of one pizza, 1/2 is left of one pizza.

If they didn't eat 2/4 of the other pizza, 2/4 is left of that other pizza/

2/4+1/2=2/4+2/4=1

Therefore, 1 pizza was left

In China, where many couples were allowed to have only one child, the probability of a baby being a boy was 0.545. Among six ran
wariber [46]

Answer: 0.9738

Step-by-step explanation:

This is solved by the probability distribution formula for random variables where probability of determining random variable X is given by

P(X=r) = nCr * p^r * q^n-r

Where n = number of sample = 6

p = probability of success = 0.545

q = 1-p = 0.455

r = possible outcome from number of sample.

If 6 random births are chosen, Probability that at least 1 of them is a girl = 1 -[probability that none of them is a girl] = 1 - [probability that all 6 kids are boys]

Probability that all 6 kids are boys = 6C6 * 0.545^6 * 0.455^0 = 0.0262

Probability that at least one is a girl = 1 - 0.0262 = 0.9738.

Is (3,7), (3,8), (3,9), (3,10) a function
pogonyaev

Answer:

(3,7), (3,8), (3,9), (3,10) is not a function.

Step-by-step explanation:

A function is defined as a relation in which each input value has only a single output value.

This means that for each x value there should be only one y  

value. If this criteria is not fulfilled then the relation cannot be called a function.

For the given set of points, we notice that for x=3, y=7,8,9,10 which shows there are many y-values o for a single x-value. This means there are many outputs for a single input. This disqualifies it to be a function.

Thus, (3,7), (3,8), (3,9), (3,10) is not a function.

What is the solution set for the given inequality if the replacement set for r is {5, 6, 7, 8, 9, 10}?
tangare [24]

Answer:

{6,7,8,9,10}

Step-by-step explanation:

Solve the inequality using inverse operations.

3r\leq 4r-6\\3r-4r\leq -6\\-r\leq -6\\r\geq 6

This solution means values equal to or larger than 6 from the set are solutions. This means 6, 7, 8, 9, and 10 are the solution set.
