Answer:

x = 44.5

Step-by-step explanation:

The angles defined by x will be supplementary when the lines m and n are parallel.

(x +4) +(3x -2) = 180

4x +2 = 180

4x = 178

x = 44.5 . . . . will make m and n parallel

Amalia and Alec are studying the growth of a plant over time. They measure the height of the plant at the end of each week for s

EleoNora [17]

After 7 weeks the plant will 11.25 units tall if the equation for the best-fit line to be y = 2.5 + 1.25x.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

$\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\rm c = \dfrac{\sum y -m \sum x}{n}$

We have a line of best fit:

y = 2.5 + 1.25x

Plug x = 7 weeks

y = 2.5 + 1.25(7)

y = 11.25 units

Thus, after 7 weeks the plant will 11.25 units tall if the equation for the best-fit line to be y = 2.5 + 1.25x.

Find the sum of the A.P:8,-3,-2,-7,-12....up to n terms

Ira Lisetskai [31]

Answer:

$\frac{21n}{2} -\frac{5n^{2} }{2}$

Step-by-step explanation:

given ap series : 8,3,-2,-7,-12....up to n terms

[the second term should be +3 or else it wont form AP series]

first term in the series: 8

common difference : 3-8 = -5

total terms : n

the formula for sum of n terms in an ap = $\frac{n}{2} [2a+(n-1)d]$

a: first term

d: common difference

n : total terms

by substituting value in the above formula,

sum of the A.P: $\frac{n}{2} [2(8)+(n-1)-5]$

$\frac{n}{2} [16+(n-1)(-5)]$

$\frac{n}{2} [16+-5n+5]$

$\frac{n}{2} [21+-5n]$

= $\frac{21n}{2} -\frac{5n^{2} }{2}$
