Step-by-step explanation:
Maybe you want the value of 16/f when f=4. Put the value of f where f is and do the arithmetic.
Answer:
C
Step-by-step explanation:
This is because using the formula of area for shapes, you get this equation
A=2(wl+hl+hw)=2·(4·6+4·6+4·4)=128
Answer:
1.25 * N
Step-by-step explanation:
We have to increase N by 25%.
The first thing is to say how the percentage works in these cases, N would be our 100% and the increase would be 25% in this case, therefore, the initial value must be added (that is, N, 100%) and to that if add 25% of the initial value (that is, + 25% N).
Thus:
100% * N + 25% * N = N * (100% + 25%)
N * (125%) = 1.25 * N
So to increase N is 25% it would be 1.25 * N
Answer:
0.0455
Step-by-step explanation:
<u>The formula for calculator probability is
</u>
# of favorable outcomes / # of possible outcomes
<u>The total number of marbles in the bag: </u>
7+3+2=12
<u>Probability of the first marble being blue:</u>
3/12
<u>Probability of the second marble being blue:</u>
2/11 -- 2 because only 2 blue marbles left after drawing the first one out, 11 because after taking the first marble out, we have 11 marbles left in the bag
<u>Formula for both events happening:</u>
p(A and B) = p(A) * p(B)
In this problem,
A = first one blue
B = second one blue
<u>Probability that if two marbles are drawn out of the bag, both are blue:</u>
3/12 x 2/11 = 0.045454
<u>Rounded answer:</u>
0.0455 (or 4.55%)
Answer:
the end is 24.6 because 30-18% is equal to 24.6
