Answer:

y = 1/2x + 7

Step-by-step explanation:

Parallel lines have the same slope.

Therefore the new equation will have a slope(m) = 1/2

Substitute m = 1/2 and point (-2, 6) into y = mx + b to solve for "b"

y = mx + b

6 = 1/2(-2) + b

6 = -1 + b

7 = b

The new equation: y = mx + b

y = 1/2x + 7

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

Pete grabbed 18 mixed nuts, StartFraction 2 Over 9 EndFraction of which were almonds. Which equation shows how to determine the

djverab [1.8K]

Answer:

18 times StartFraction 2 Over 9 EndFraction = 4

Amount of almonds = 18 × [2/9]

Amount of almonds = 4 almonds

Step-by-step explanation:

Given:

Number of mixed nuts = 18

Probability of almonds = 2/9

Find:

Amount of almonds

Computation:

Amount of almonds = Number of mixed nuts × Probability of almonds

Amount of almonds = 18 × [2/9]

Amount of almonds = 36 / 4

Amount of almonds = 4 almonds

What is the 4th term in a geometric sequence for which a1=15 and r=1/3

Hitman42 [59]

Geometric goes liket his
$a_n=a_1(r)^{n-1}$
given
a1=15
r=1/3
find a4 or 4th term

$a_4=15( \frac{1}{3} )^{4-1}$
$a_4=15( \frac{1}{3} )^{3}$
$a_4=15 (\frac{1}{27})$
$a_4=\frac{15}{27}$
$a_4=\frac{5}{9}$
4th term is 5/9
