Find the approx. slope of the regression line through the given 5 points.  As x increases from 9 to 45 (a change of +36), y increases from 5 to 25, or 20.
                                                                                     20         5
Thus, the slope of the regression line is approx. m = ------ = -----
                                                                                     36         9
We need to continue, to find the equation of this regression line.

Since the slope is 5/9 and one point on the line is (25,12), the equation of the line is:

y-12 = (5/9)(x-25).

Now let x = 80 and calculate y:      y = 12 + (5/9)(55) = 12 = 42.6

When the # of apples is 80, the weight of the apples is approx. 43 lb.

Sorry for being late but it’s go up 1 and right 9. ( you can remember this in the way that 1 is going up and 9 is going right, if it’s negative it would be -1 going down and -9 going left) hope this helps!

What is the value of x
disa [49]

Answer:

x = 15 degrees

Step-by-step explanation:

This is a right angle, since we know that a right angle contains 90 degrees, we can form an equation.

30+4x=90

Now, we solve for x.

-30+30+ 4x = -30+90

4x=60

\frac{4x}{4}=\frac{90}{4}

x=15

I need help with this

Answer:

A) (-8, -16)

B) (0, 48)

C) (-4, 0), (-12, 0)

Step-by-step explanation:

A) the vertex is the minimum y value.

extremes of a function we get by using the first derivation and solving it for y' = 0.

y = x² + 16x + 48

y' = 2x + 16 = 0

2x = -16

x = -8

so, the vertex is at x=-8.

the y value is (-8)² + 16(-8) + 48 = 64 - 128 + 48 = -16

B) is totally simple. it is f(0) or x=0. so, y is 48.

C) is the solution of the equation for y = 0.

the solution for such a quadratic equation is

x = (-b ± sqrt(b² - 4ac)) / (2a)

in our case here

a=1

b=16

c=48

x = (-16 ± sqrt(16² - 4×48)) / 2 = (-16 ± sqrt(256-192)) / 2 =

= (-16 ± sqrt(64)) / 2 = (-16 ± 8) / 2 = (-8 ± 4)

x1 = -8 + 4 = -4

x2 = -8 - 4 = -12

so the x- intercepts are (-4, 0), (-12, 0)

Solve the questions for x?<br><br> 1/2 X + 5 = 18
rodikova [14]

Answer:x = 6.5

Step-by-step explanation: Subtract 5 from both sides and you get 1/2x=13 then isolate the x by dividing both sides by 1/2 to get x=6.5.

How many yards are in 2 millimeters
AleksandrR [38]
In 1 millimeter, there are 0.00109361
So in 2 mm, there are 2 × 0.00109361 = 0.00218722 yards

or do proportions:
\frac{1mm}{0.00109361yd} = \frac{2}{y}

Cross multiply:

2 × 0.00109361 = y
0.00218711 = y 

0.00218722 yards are in 2 millimeters.
