Answer:
$0 < p ≤ $25
Step-by-step explanation:
We know that coach Rivas can spend up to $750 on 30 swimsuits.
This means that the maximum cost that the coach can afford to pay is $750, then if the cost for the 30 swimsuits is C, we have the inequality:
C ≤ $750
Now, if each swimsuit costs p, then 30 of them costs 30 times p, then the cost of the swimsuits is:
C = 30*p
Then we have the inequality:
30*p ≤ $750.
To find the possible values of p, we just need to isolate p in one side of the inequality.
So we can divide both sides by 30 to get:
(30*p)/30 ≤ $750/30
p ≤ $25
And we also should add the restriction:
$0 < p ≤ $25
Because a swimsuit can not cost 0 dollars or less than that.
Then the inequality that represents the possible values of p is:
$0 < p ≤ $25
In this case the two equations<span> describe lines that intersect at one particular point. Clearly this point is on both lines, and therefore its coordinates (x, y) will satisfy the </span>equation<span> of either line. Thus the pair (x, y) is the one and only </span>solution to the system of equations<span>.</span>
Answer:
(A) Binomial
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they are left-handed, or they are not. This is the first condition for the random variable X being binomial.
The selections are independent, that is, the probability of a person being left handed is independent from other people. This is the second condition for the random variable X being binomial.
Since both conditions(only two outcomes, independent trials) are satisfied, the random variable X is binomial.
So the correct answer is:
(A) Binomial
I would so go with B I'm not sure if that's the correct answer though but that's what I would go with
Answer: b=y+3/x
Step-by-step explanation:
bx-3=y
bx-3+3=y+3
bx=y+3
bx/x=y+3/x
