3+8x-2y-x+1+4y
Combine all like terms and
7x+4+2y is your answer
Answer:
i am not so sure but I think its 10x = 33
Answer:
Step-by-step explanation:
Given that the weights for a population of North American raccoons have a bell-shaped frequency curve with a mean of about 12 pounds and a standard deviation of about 2.5 pounds
Since bell shaped is given we can assume that this follows a normal distribution symmetrical about the mean.
To find 95% two values we can use Z critical value for 95%
i.e. ±1.96
95% will lie between 12±1.96(2.5)
= 12±4.9
=(7.1, 16.9)
For the 1st one i believe its Y=6
And the second one is Y=1
Radius = 11 / 2 = 5.5
A = π * 5.5 * 5.5
A = 30.25 <span>π

3025 / 100 <span>π mm^2</span>
