Using a calculator, the equation for the line of best fit where x represents the month and y represents the time is given by:

a. y = −1.74x + 46.6

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (x,y) are given as follows, from the given table:

(1, 46), (2, 42), (3,40), (4, 41), (5, 38), (6,36).

Hence, inserting these points in the calculator, the equation for the line of best fit where x represents the month and y represents the time is given by:

a. y = −1.74x + 46.6

The human population of the earth can be modeled by p(T)=3.1(1.016)^t , where T represents the number of year since 1963 , and p

Mkey [24]

Answer:

See below

Step-by-step explanation:

<u>Given function:</u>

p(t)=3.1(1.016)^t

<u>The base of the growth rate is:</u>

1.016 = 1 + 0.016

It represent a 1.6% of growth per year.

Increasing

<u>p(55) = 7.42 means:</u>

55 years after 1963, in the year 2018, the population of Earth is 7.42 billions

Help I dont know how to write the equation. I know its y=xb or y=x+b <br>

34kurt

Answer:

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

linear equation
PEMDAS

<h3>given:</h3>

b=-2

<h3>let's solve:</h3>

the slope of the line is 1

and linear equation slope intercept form:

y=mx+b

therefore our equation is

y=x+(-2)
y=x-2

Help me please. Find the measures of CAD and DAE

VladimirAG [237]

well, we know the "sum" of both angles is 90°, notice the rectangle in the corner, so we can say that the angles are simply complementary angles, thus

$\left( \cfrac{3}{2}x+20 \right)+2x=90\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{2}}{2\left( \cfrac{3}{2}x+20 + 2x \right)=2(90)} \\\\\\ 3x+40+4x=180\implies 7x+40=180\implies 7x=140\implies x=\cfrac{140}{7} \\\\\\ x = 20~\hfill \stackrel{\measuredangle CAD}{\cfrac{3}{2}20+20\implies 50}\qquad\qquad \stackrel{\measuredangle DAE}{2(20)\implies 40}$

Three angles are complementary. Two of the angles are equivalent. If the third angle is 10 degrees, what must be the measurement

kompoz [17]

if three angles are complementary, then they all ad up to 90 degrees. if the third angle is 10 degrees, then there are multiple answers for the other angles. one could be 35 degrees and 45 degrees.
