Answer:
8%
Step-by-step explanation:
new length = 110% x 30 = 33cm
new width = 105% x 20 = 21cm
new perimeter = 2(33 + 21) = 108cm
old perimeter = 2(30 + 20) = 100cm
percentage increase = 8/100 x 100% = 8%

B. Not a function because both (3,6) (4,6) have the same y making them not a function
Answer:
1. re-arrange numbers in order.
37, 38, 43, 45, 57, 57, 58
THE MEDIAN IS 45
2. To find Mean, add up all the numbers then divide by how many numbers there are.
when added together, it is 335
335 / 7
47.857
THE MEAN IS 47.857

<u>Factorizes:</u>
⇒ a² + 8a + 16 = 0.
<u>As we know that,</u>
Factorizes the equation into middle term splits, we get.
⇒ a² + 4a + 4a + 16 = 0.
⇒ a(a + 4) + 4(a + 4) = 0.
⇒ (a + 4)(a + 4) = 0.
⇒ (a + 4)² = 0.
⇒a=<u>-</u><u>4</u><u>.</u>

Answer:
The probability that the product of 2 numbers that Drake rolls is less than =
Step-by-step explanation:
Drake rolls two fair number cubes i.e. 6 sided die. He then multiplies the numbers shown on each die. The result of the all possible products are shown in the given table. The given table is missing a 1 in the first row. The complete first row will be:
1 2 3 4 5 6
The total number of possible outcomes are 36. We have to find the probability that product of two numbers that Drake rolled is less than 10. For this, first we need to count the number of outcomes that are less than 10. From the table we can see that the number of possible outcomes that are less than 10 are = 17
Probability is defined as the ratio of favorable outcomes to the total number of outcomes. Here, total outcomes are 36 and favorable outcomes are 17.
So,
The probability that the product of 2 numbers that Drake rolls is less than =
