A 1st degree function can be written in two ways:
F(X) = AX + B
or
Y = AX + B
note that F(X) = Y
So, looking at the alternatives in the question, only Y = 7X/3 - 8 is equivalent to Y = AX + B, where:
A = 7/3
B = - 8
then
<em>a function of the 1st degree</em>
answer:
<h2>Y = (7/3)X - 8</h2>
Answer:
<h2>See the explanation.</h2>Step-by-step explanation:
3 or less than 3 tires among the 10 tires should be blemished.
There are some possibilities.
1000 tires are blemished, (5000 - 1000) = 4000 tires are not blemished.
From the 5000 tires, 10 tires can be chosen in ways.
Possibility 1: <u>3 tires are blemished.</u>
Total 10 tires can be chosen with 3 blemished tires in ways.
Possibility 2: <u>2 tires are blemished.</u>
Total 10 tires can be chosen with 2 blemished tires in ways.
Possibility 3: <u>1 tires are blemished.</u>
Total 10 tires can be chosen with 1 blemished tires in ways.
Possibility 4: <u>No tires are blemished.</u>
Total 10 tires can be chosen with no blemished tires in ways.
Hence, the required probability is .
