Answer:
12
Step-by-step explanation:
Given the data :
X : 10,8,18,17,7
The mean value of scores obtained can be obtained thus :
Mean = ΣX / n
n = sample size = 5
Mean = ΣX / n = (10+8+18+17+7) / 5
Mean = 60 / 5 = 12
Answer:
Step-by-step explanation:
Given
The given parameters show that P is a point between O and Q.
So:
Substitute values for OP, PQ and OQ
--- This is an equation

Make x the subject
22 × 35= 770
770 × 18= 13,860
13,860 × 105= 1,455,300
1,455,300 ÷ 2,000= 727.65
727.65 rounded to the nearest whole ton is 728
so the and answer is 728 tons
8 + 0.4 + 0.07 + 0.008 is your answer. But all you had to do is separate your numbers with working on the biggest number to the smallest number.
Hello,
I would be happy to help.
For Part A, you just count the number of terms, there are 3. So, it is a trinomial.
For Part B, you look at the highest exponent value, it is 2. So it is a second degree polynomial.
For Part C, you have to sub in the values for each year. You are looking for the number of years since 1930, so subtract 1930 from each year.
2020 - 1930 = 90
2030 - 1930 = 100
Then, sub in those values into the given expression to find the density.
0.005(90)^2 - 0.127(90) + 1 = 30.07
0.005(100)^2 - 0.127(100) + 1 = 38.3
Remember to use the order of operations!
Good luck,
MrEQ
