Neporo4naja [7]

Complete question :

Carly purchased 9 1/2 pints of ice cream for a party. If each guest will be served exactly 3/5 pint of ice cream, what is the greatest number of gusts that Carly can serve

Answer:

15 guests

Step-by-step explanation:

Given that:

Total pints of icecream = 9 1/2

Fraction of ice cream pints per guest = 3/5 pints

Number of guest that can be served :

Total pints / fraction per guest

9 1/2 ÷ 3/5

19/2 * 5/3

95 / 6

= 15.8 guest

Hence, greatest Number of guest that can be served = 15

What is the meaning of a composite number?
zaharov [31]
Composite number is a positive integer that can be formed by multiplying together two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.[1][2] Every positive integer is composite, prime, or the unit 1, so the composite numbers are exactly the numbers that are not prime and not a unit.

For example, the integer 14 is a composite number because it is the product of the two smaller integers 2 × 7. Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself

The probability that a data communications system will have high selectivity is 0.72, and the probability that it will have high
34kurt

Let us assume that even F represents fidelity and event S represents selectivity.

We have been given the probabilities:

P(S) = 0.72, P(F) = 0.59 and P(S\cap F)=0.33

We need to find the conditional probability that a system with high fidelity will also have high selectivity. We know the conditional probability formula:

P(\frac{S}{F})=\frac{P(S\cup F)}{P(F)}

Upon substituting the given values, we get:

P(\frac{S}{F})=\frac{0.33}{0.59}

P(\frac{S}{F})=\frac{33}{59}=0.56
