(a)The amount of soil he had last week
(b) p/2+4=28
(c) 12 because
(d) 12
Answer:
I think it should be
Step-by-step explanation:
When the question said area of the cube, I think it was supposed to be surface area, which would where a is the length of one edge. Given that the length of one edge is 2x, we would plug in 2x to the equation to get which would become .
<em>9 - 4(2p - 1) =45</em>
<em>5(2p - 1) = 45</em>
<em>10p - 5 = 45</em>
<em>10p = 45 + 5</em>
<em>10p = 50</em>
<em>p = 50/10</em>
<em>p =5 (ans)</em>
Answer:
Choice B
The mathematical model that best fits the data is a polynomial of order 2 as shown on the attachment.
The predicted global mean temperature in 2015 is; 412.24
Step-by-step explanation:
The first step is to obtain a scatter plot of the data and then fit a trend line. A quadratic polynomial fits the data well considering the large value of the coefficient of determination of 0.9984.
To determine the global mean temperature in 2015 we substitute x with 14 in the quadratic model;
y = 0.4643(14)^2 + 0.7976 (14) + 310.07
= 412.24
Answer:
C.
Step-by-step explanation:
Adding to the x value makes a point go appear more right. Subtracting some from the y value makes a point go appear down.
