Answer: 60
Step-by-step explanation: 60 because if you do 3×20 You get 60 which is higher than 50 and lower than 100 :)
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
Answer:
y=2
Step-by-step explanation:
With the given values in the equation for a straight line (y=mx+c)
where x and y are the graph coodinates
m is the gradient
and c is the y intercept
substituting the given values into the equation gives
y=2
given that 0 multiplied by anything is 0 so the mx preportion of the equation is cancelled
The answer is 48$ hope I helped you
Answer:
<h2><u><em>57°</em></u>
</h2>
Step-by-step explanation:
You can notice that by putting ∠3 and ∠TKL together you have a flat angle.
A flat angle has 180 degrees.
so, you can say that m∠3 and m∠TKL add 180 degrees, then they are supplementary angles.
Remember: Two angles are supplementary if they add 180 degrees.
Then, as you know m∠3=123°:
m∠3 + m∠TKL=180°
123 + m∠TKL=180°
m∠TKL=180° - 123°
m∠TKL=57°
