Answer: 30
Step-by-step explanation:
Given :The weight of a bag of golf balls varies directly as the number of golf balls in the bag.
Let x be the number of golf balls in a bag that weighs 1,110 grams.
Then we have the following direct variation equation,
Multiply 1110 both sides , we get
Hence, there are 30 balls in the bag.
Answer:
Step-by-step explanation:
Represent Green with G
So,
Required
Determine the probability that 10 out of 16 prefer green
This question is an illustration of binomial distribution and will be solved using the following binomial distribution formula.
In this case:
-- number of people
-- those that prefer green
So, the expression becomes:
Substitute 50% for G (Express as decimal)
Apply law of indices
Solve 16C10
<em>Hence, the required probability is 0.1222</em>
You're 42. 42-21=21 and 21x2=42.
ANSWER
2x² + 7x + 5
EXPLANATION
This is a quadratic function, because it has two 'x' multiplying in different terms.
The standard form of a quadratic function is:
To transform this expression in standard form we have to apply the distributive property to multiply the terms in the parenthesis:
So for this expression a = 2, b = 7 and c = 5.
A and B
8/16 = 1/2
A=1/2
B=2/3
C=1/2
D=1
