Answer:
greater than ............
Answer:
32 - 2.5x - 2y
Step-by-step explanation:
He bought 2.5 pounds weight of apples for x dollars a pound. Thus, cost is 2.5x.
He bought 2 bags of lettuce for y dollars each. Thus, cost is 2y
Total bill cost = 2.5x + 2y
We are told he has a coupon for $2 off his bill.
This means the amount he will pay will now be;
2.5x + 2y - 2
Gabriel has $30 to pay for the groceries.
Thus, his change will be;
30 - (2.5x + 2y - 2)
This gives;
32 - 2.5x - 2y
Step-by-step explanation:
a) D=(-1,5) E=(-3,1)
b) you do it by adding B coordinates with each other and C coordinates with each other then comparing how its related to D coordinates and E coordinates. B=2+6=8
C= -2-2= -4 D= -1+5= -4 E=-3+1= -2.
or tou can try another method which is knowing the length of each line.
Find out the value of z
Remember that
z =(x - μ)/σ
we have
μ=18
σ=5
For x=5
substitute
z=(5-18)/5
z=-2.6
Using a z-scores table
we have that
P(x ≥ 5)=0.99534
therefore
<h2>the answer is option A</h2>
