Hi!
As per graph and question,
a) The most challenging is:-
<u>Examination B</u>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>Reason</em> - There are few high scores and many low scores.
b) The least challenging is:-
<u>E</u><u>x</u><u>a</u><u>m</u><u>i</u><u>n</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u><u>C</u>
<em>Reason</em>- There are many high scores, few low scores and the lowest mark is not zero.
Answer:
14 and 10
Step-by-step explanation:
We have the equation x(x-4)=140. We can distribute the x to everything in the parenthesis so it's easier to work with.
x(x-4)=140
Let's move 140 to the left side, so we can solve this equation better by finding the zeros of the equation.
To find the zero, we have to find TWO values that multiply to -140 but add to -4.
(x-14)(x-10)=0
To find the zeros. make both of those parenthesis equal to zero.
x=14, 10
APY=(1+r/k)^(k)-1
R = 0.1236
K compounded twice a year 2
APY=(1+0.1236÷2)^(2)−1
APY=0.1274×100=12.74%
Answer:
k ≥ -18
Step-by-step explanation:
-8 ≥ 2/5(k-2)
-8 ≥ 2/5k - 4/5
(-8 ≥ 2/5k - 4/5) 5
-40 ≥ 2k - 4
+4 +4
-36 ≥ 2k
-36 divided by 2
2 divided by 2
-18 ≥ k
flip the greater than or equal to sign to the k.
k ≥ -18
