Answer:
B is the answer
Step-by-step explanation:
take two of the points to plug in and test
point one, when x is 3 y is 9
y=2/3 (3) +7
y=6/3 +7
y= 2 + 7
y=9
test the next point
(9,13)
y=2/3 (9) + 7
y=18/3 +7
y= 6 +7
y=13
Answer:
P=-6
Step-by-step explanation:
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.
Since you have two numbers that have a (x) at the ends of them, you add those first then add seven which will end up being 9x+7
50% should be the present increase :)
