Answer:
See below
Step-by-step explanation:
To find the mean, you take each data point, add them together, and divide it by the number of data points.
<u>Problem 1</u>
Mean of High Temperatures = (65+67+54+52+63+69+75)/7 = 445/7 = between 63 and 64
<u>Problem 2</u>
Mean of Low Temperatures = (61+55+37+29+34+42+54)/7 = 312/7 = between 44 and 45

The answer is D,
a(n) = 4/5 + 1/6(n- 1)
just took the test :)
3x^2-6x+3=0
x^2-2x+1=0
x^2-x-x+1=0
x(x-1)-(x-1)=0
(x-1)(x-1)=0
x=1,1
so x has only one answer
so it intersects only one time
