0.4n-3(n+0.1)
0.4n-3n-0.3
-2.6n-0.3
Answer: You would share in exactly 55 squares.
Step-by-step explanation: To solve this, you need to know how to convert, divide, and multiply.
10*10=100
100/n=20
n=5
11*5=55
SO, you shade in 55 squares.
Remember, "mean" means the average of the numbers.
In order to find an average, add all the numbers together, then divide by the amount of numbers.
So:
1+5+7+9+11+16+18+20+30+35=153
Since there are 10 numbers in the sequence, divide by 10.
153/10=15.3
Answer:
the probability when the IQ is lower than 136 is 0.9641
Step-by-step explanation:
Given that
The mean is 100
The standard deviation is 20
We need to find out the probability when the IQ is lower than 136
So,
z value equivalent to 136 = (136 - 100) ÷ 20 = 1.8
Now
p (z < 1.8) = 0.9641
hence, the probability when the IQ is lower than 136 is 0.9641
