Answer:
I attached a pic
Step-by-step explanation:
Hope it helps you!!!
x^2 in the function that you typed is x * x ( x multiplied by x). It represents a second degree because there are only 2 "x"s multiplied together. If there were 3 "x"s multiplied together, we would have x^3. Since the highest exponent in this function is 2 (in x^2), we call this function a 2nd degree polynomial.
Answer:
The variance of the temperatures of the 10 day period must be at least zero.
Step-by-step explanation:
The variance is the expectation of the squared deviation of a random variable from its mean. It measures how far a set of numbers are spread out from their average value.
Its unit of measure corresponding to the square of the unit of measure of the variable. In this case, the variance of the temperatures is expressed in (°C)². The variance has a minimum value of 0.
Since the variance is squared, it will always have values greater than zero.
(-24,-2)(-15,-8)
slope = ( - 8 - (-2) / (-15 - (-24) = (-8 + 2) / (-15 + 24) = -6/9 = - 2/3
y = mx + b
slope(m) = -2/3
use any of ur points (-24,-2)...x = -24 and y = -2
now we sub and find b, the y int.
-2 = -2/3(-24) + b
-2 = 16 + b
-2 - 16 = b
-18 = b
so ur equation is : y = -2/3x - 18
now in y = mx + b form, the y int is in the b position
y = mx + b
y = -2/3x - 18
so ur y intercept is -18 or (0,-18) <=====
to find the x int, sub in 0 for y and solve for x
y = -2/3x - 18
0 = -2/3x - 18
2/3x = -18
x = -18 * 3/2
x = - 54/2 = -27....and ur x intercept is -27 or (-27,0) <===
