The rules of rounding are fairly simple. If the number to the right of the number you are rounding is greater than or equal to 5, you round up. If the number to the right is less than 5, you round down.
Let's take a look at the number 12.345.
First, round to the hundredths place. The number right before the 4 is 5, so we round up. This gives us the number 12.35.
Next, we have to round to the tenths place. The number to the right of the 3 is 5, so we round up as well. This gives us the number 12.4.
Answer: 12.4

The cost of the first light fixture is $27.
Given that, a customer returned a light fixture to the store in exchange for a $52 light fixture and three gallons of paint at $29 each.
What is an equation?
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the cost of first light fixture be x.
Now, x=52+3×29 - 112
=52+87 - 112
= 139 - 112
= 27
Therefore, the cost of the first light fixture is $27.

$29 times 3 is $87
$112-$87 = $25
52-25= 35
The customer paid $35 for the first light fixture. I think.

You already know what y is in terms of z so put it into the other equation
3(15-2z)=3 -4z
45-6z=3-4z
42=2z

explanation 1/4 is half of 1/2 so 52.5 is half of 105 and then 210 for an hour of travel
Answer:
105 at 30 min.
x at 75 min.
105 mph x 2 = 210 mph at one hour
There is still 15 min to go soooo...
210/4 = 52.5
210 + 52.5 = 262.5 mph for 75 min
Check by dividing
262.5/75=3.5
arrive late. Valerie used the random-number table to find the experimental probability that of 5
flights, at least 2 will arrive late. The digit 0 represents flights arriving early. The digits 1,2,3,
4, 5, and 6 represent flights arriving on time. The digits 7, 8, and 9 represent flights arriving
late. Find the experimental probability that of 5 flights at least 2 will arrive late.
A: 3/10
B:2/5
C: 9/20
D: 11/20
Answers
Answer:
D. 11/20
Step-by-step explanation:
7, 8, and 9 represent late flights. We want to count how many of the 20 trials have at least two of these digits. Counting, we find that 11 of the 20 have at least two of these digits.

Answer:
The probability that both of the selected marbles are red is
Step-by-step explanation:
Given
Number of red marbles = 3
Number of blue marbles = 5
Required
Probability of selecting two red marbles (without replacement).
First, we need to get the total number of marbles
Total = Red Marbles + Blue Marbles
Total = 3 + 5
Total = 8
Probability is calculated by: Number of required outcome divided by number of possible outcome.
Since there are 3 red marbles out of a total of 8 marbles;
The probability that the first marble you selected is red is 3/8
From the question, you didn't return the marble back to the container.
This means that, there are 2 red marbles and a total of 7 marbles left in the container.
So, the probability that the next marble selected is red is 2/7
Let P(R and R) represent the probability of selecting two red marbles.
This is calculated by multiplying the probability of picking the first red marble and the second red marble.
Hence,
P(R and R) =
P(R and R) = --- Reduce to lowest term
P(R and R) =
Hence, the probability that both of the selected marbles are red is
