Answer:
<em>2.5%</em><em> of the snakes are longer than 16.6 in</em>
Step-by-step explanation:
The Z score is,
here,
X = raw score = 16.6
μ = mean = 15
σ = standard deviation = 0.8
So,
Z-score is the measurement of how many standard deviation away the data is from the mean. Hence, the value 16.6 is 2 standard deviations right to the mean.
Approximately 95% of the data falls within two standard deviations of the mean. (between the mean-2 times the standard deviation, and the mean+2 times the standard deviation)
So the 5% of data are left in the remaining space. As we have to find the amount of snakes which are longer than 16.6 in i.e we have to find the area to the right of 16.6.
The remaining 5% of amount is divided in two equal parts.
Therefore, 
of the snakes are longer than 16.6 in
Replace x and y in the equation with the given point and solve:
-4(-3) - 10(2) = 12 -20 = -8
-8 is not less than -9
(-3,2) is not a solution.
The equation that describes the which gives the area of the pen, A, as a function of x, the length of fence parallel to the barn is A = 130x - x²
<h3>How to find area of a rectangle?</h3>
The pen is rectangular. Therefore,
area of a rectangle = lw
where
Therefore,
perimeter = 2w + l
perimeter = 2w + x
130 = 2w + x
130 - x = 2w
w = 65 - 1/ 2 x
A = xw
A = x(65 - 1/ 2 x)
A = 65x - 1 / 2 x²
Therefore, the function that represents A, the area of the pen is as follows:
A = 130x - x²

To get the average you need to add all the numbers together and divide by the match number. So, 98+25+105+62+65=355. 355/5=71, therefore the average is 71
Answer:
(x + 4)
Step-by-step explanation:
x - 2 = 0, so x = 2
x - 4 = 0, so x = 4
x - 6 = 0, so x = 6
