Answer:
The answer is supplementary
Step-by-step explanation:
supplementary angles add to 180 degrees
So I’ll do question 3. So normally you see f(x)= something plus x (something like that) you see it as a function of x.
So that notation of f(-1) means the function of -1. Which means you need to sub in -1 for x.
f(x)=-5x+5
f(-1)=-5(-1)+5
Negative times a negative is a positive
f(-1)=5+5
f(-1)=10
Answer:
that would be 2% ig

Answer:
The percentage of the beams will be rejected is 1.24%
Step-by-step explanation:
Given information:
Mean, μ = 8 ft
standard deviation, σ = 4 inches
Quality requirements demand a beam to be rejected if the length is more than 10 inches
P = P (- 10/4< z < 10/4)
= P (-2.5 < z < 2.5)
= P (z < 2.5) - P(z< -2.5)
= 0.012419
The percentage of the beams will be rejected is 1.24%
Answer:
<h2> 2 trips</h2>
Step-by-step explanation:
first, we need to model an expression, the solve, say
let the total amount charged by taxi be y
and let the number of kilometers be x
y=2x+9
given that uber charges $5
then the number of taxi trips that will equal urber charge is
y=2x+9=5
5=2x+9
solving for x we have
2x+9-5=0
2x+4=0
2x=-4
x=-2
x=2 (x cannot be negative)
