Answer:
x = 22
y = 35
Step-by-step explanation:
Because its an isosceles triangle, you know the base angles are equal so:
Solving:
subtract 2x from both sides
add 11 to both sides
Next, find the angle measures of the two base angles:
To find y, you know that the interior angles of the whole triangle add up to 180, so you have
solving,
subtract 110 from both sides
divide both sides by 2
Answer:
221
Step-by-step explanation:
2 - 1 + 5 · 4 · 11 = 2 - 1 + 20 · 11 = 2 - 1 + 220
2 - 1 + 220 = 1 + 220
The decimal .53 has the 3 in the hundredths place, so the fraction that this was originally is
. When you divide 53 by 100 on your calculator, you will get backk .53
3) This is definitely a positive association, but the question is - is it linear?
Since a somewhat straight line can be drawn through the points, it is linear.
<span>
Answer: positive linear association </span>
4) Find the slope using the formula
m = 43 - 48/ 4 - 2 = -5/2 = -2.5
Negative association, but is it linear? Lets find out
Oh no! It seems that their is not a pattern in the association, so its nonlinear!
Answer: Negative nonlinear association5) <span>
m = 80 - 66/ 5 - 3
m = 14/2
m = 7
Positive! But is it linear??
Let us draw a graph this time.
I know my graph is messy, but can you see the nonlinear-ness? It doesnt form a straight line!
Answer: Positive nonlinear association </span><span>Hope this helped. :) </span>
