Answer:
−9⋅(5j+k) = -45j -9k.
Step-by-step explanation:
Given : −9⋅(5j+k)
To find : distributive property.
Solution : −9⋅(5j+k)
By distributive property a( b +c ) = a*b + a*c.
Then −9⋅(5j+k) = -9 *5j + (-9 *k)
−9⋅(5j+k) = -45j -9k.
Therefore, −9⋅(5j+k) = -45j -9k.
Answer and explanation:
1. It is commonly referred to as the arithmetic average: the mean measure of central tendency is also referred to as the arithmetic mean or arithmetic average or just average.
It is algebraically defined (that is, there is an equation you can use to calculate its value): the mean can be represented by the algebraic equation
a1+a2+a3...ai/n
2. There can be more than one median where there are an even number of data points and not odd number, in which the two middle number are divided by 2
It can be found when there are undetermined scores: median can be found with undetermined scores
3. It corresponds to an actual score in the data: the mode is an actual value in the data that appears more frequently than other values
There can be more than one: there can be more than one mode(bimodal,trimodal,multimodal) where 2 or more values appear the same number of times
Answer:
2x2-3x-5=0
Step-by-step explanation:
(2x2 - 3x) - 5 = 0
When solving this equation, you get the answer as -43.5.
To solve, we simply need to collect like-terms and then rearrange to get x on one side and numbers on the other:
(8x - 20) - 16 = 10x + 51
8x - 36 = 10x + 51
- 8x
-36 = 2x + 51
- 51
-87 = 2x
÷ 2
-43.5 = x

Answer:
B
Step-by-step explanation
115000 = 0.96p
115000 = p - 0.04p
I think It's B if the = sign in the beginning is a - sign
