Answer:

Step-by-step explanation:
so you want to start by using y=mx+b
step one: find the slope (remember m is the slope in this)
m= 
m= 
m= 
m= - 
step two: insert the value we found for m into the equation and take one of the given points and insert the x and y into the equation (im using (0,5)) and solve for b.
y=mx+b
5= -4/3(0)+b
5=b
step three: rewrite y=mx+b with the values we found for m and for b

Jade is twice as old as y (Sara).
The expression would be 2y.
If you multiply y (Sara's age), then you would get Jade's age.
Answer:
{2,3,5,6,8}
Step-by-step explanation:
U={1,2,3,4,5,6,7,8}
A{3,4,5,6}
B{1,4,8}
C{2,3,4,5,6}
We are to find
{A' n B} U {A' n C'}
={3,5,6,8}. U. {2}
= {2,3,5,6,8}
Answer:
The number of ways to select a sample of 2 computer chips so that at least one of the chips is defective is 33 ways.
Step-by-step explanation:
The box contains 13 computer chips. Of these 13 chips 3 are defective and 10 are good.
A quality control inspector samples 2 computer chips.
The number of ways to select at least 1 defective chip is:
n (At least 1 defective chip) = n (1 defective chip) + n (2 defective chips)
The number of ways to select 1 defective chip is:
ways.
The number of ways to select 2 defective chips is:
ways.
n (At least 1 defective chip) = n (1 defective chip) + n (2 defective chips)
= 30 + 3
= 33
Thus, the number of ways to select a sample of 2 computer chips so that at least one of the chips is defective is 33 ways.
6+7+3 =16
7+9+7 =23
9+6+7=22
6+8+1=15
