Answer:
1st option is True, 5% more votes for Sam than for Megan
Step-by-step explanation:
Megan, with 1/4 of vote, got 25%
Sam, with 3/10 of vote, got 30%
Alex would have received 45% of the vote
Answer: Tom's age is 40 and Bob's age is 38.
To answer this problem, you must write the 2 equations given in the directions.
They could be:
t - b = 2 and b = 3t - 82
Input the second equation into the first equation at the variable be and solve.
t - (3t - 82) = 2
t - 3t + 82 = 2
-2t + 82 = 2
-2t = -80
t = 40
So Tom is 40. And since t - b = 2, Bob must be 38.
-15/5 = -3
15/(-5) = -3
15/(-5) = -3
(-15)/(-5) = 3 (because if a negative divides a negative, it becomes positive)
The result of the given expression in simplest form is
.
The given parameters:
16÷(2+12)2
The given expression can be evaluated in the following order as shown below;
<em>add </em><em>the numbers in the </em><em>bracket</em><em>;</em>
2 + 12 = 14
<em>multiply </em><em>the numbers in the </em><em>bracket </em><em>by 2;</em>
14 x 2 = 28
<em>divide </em><em>the 16 by your result after the </em><em>multiplication</em><em>;</em>

<em>divide the </em><em>numerator </em><em>and </em><em>denominator </em><em>by their common factor which is 4;</em>

Thus, the result of the given expression in simplest form is

A bag contains 3 red marbles and 4 blue marbles. a marble is taken at random and replaced. Another marble is taken from the bag. Work out the probability that the two marbles taken from the bag are the same color.
<span>Total number of marbles in the bag is 3 + 4 = 7.<span>The problem asks for the probability of (RR) or (BB).</span>It's worthy to note we are replacing the balls after each draw, which means we always have 7 to draw from</span>Since each draw is independent, we take the product of each event for the total event probability.
P(RR) = 3/7 * 3/7 = 9/49
P(BB) = 4/7 * 4/7 = 16/49
We want to know P(RR) + P(BB)
<span>P(RR) + P(BB) = 9/49 + 16/49 = 25/49</span>
