Answer:
Option A, x ≥ -2
Step-by-step explanation:
<u>Since the line is not dotted, that means that -2 is included. Also, since the darkened part is toward positive infinity, that means that it is ≥.</u>
<u />
So, it is <em>x ≥ -2</em>
Answer: Option A, x ≥ -2
Answer:
<BAC=19
Step-by-step explanation:
<AOB=<DOC=142
<BAC=<ABD
2<BAC=180-142
2<BAC=38
<BAC=38/2
<BAC=19
Answer:
Yes
Step-by-step explanation:
First, we need to find how many cars out of the entire fleet fail the test
4/32 = x/150
Cross multiply to find x
32x = 150(4)
32x = 600
32x/32 = 600/32
x = 18.75
I'll round it to 19. So 19 out of 150 cars fail the test. Find the percentage of this and compare it to the 30% estimate
19 /150 = 0.127
0.127(100) = 12.7%
12.7% is obviously lower than 30% so yes it is strong evidence the percentage of the fleet out of compliance is different from their initial thought
