Estimation :
20/0.05 = 400
Answer: Choice A
y = (-3/4)(x + 4) + 6
=====================================================
Let's go through the answer choices
- Choice A is something we'll come back to
- Choice B is false because the line does not go uphill as we move from left to right. The graphed line has a negative slope, which contradicts what choice B is saying.
- Choice C is false for similar reasons as choice B. The slope should be negative.
- Choice D has a negative slope, but the y intercept is wrong. The y intercept should be 3. So choice D is false as well.
We've eliminated choices B through D.
Choice A must be the answer through process of elimination.
------------
Here's an alternative method:
If we started at a point like (0,3) and move to (4,0), note how the slope is -3/4
This is because we've moved down 3 units and to the right 4 units.
m = slope = rise/run = -3/4
We can also use the slope formula m = (y2-y1)/(x2-x1) to see this.
Then we pick on a point that is on the diagonal line. It could be any point really, but the point your teacher used for choice A is (x1,y1) = (-4,6)
So,
y - y1 = m(x - x1)
y - 6 = (-3/4)(x - (-4))
y - 6 = (-3/4)(x + 4)
y = (-3/4)(x + 4) + 6
Answer:
254
Step-by-step explanation:
the angle is 254
This is material out of the lesson of basic mathematics of compound probability.
To solve this problem, we first must count the number of outcomes (n) for this experiment. There are 2 rows of 4, so there are 8 outcomes. Now we must find what exactly the answer is looking for.
The answer is looking for the answer to the compound probability statement; P( A then B then A). If you look at the table of outcomes (results), there is one result that matches ABA. So, find the number of specific outcomes from the set of events and divide it by the total number of outcomes.
Solution:
1/8= 0.125
Answer:
<A = right angle
<B = acute angle
<C = obtuse angle
<D = acute angle
Step-by-step explanation:
Right angle = 90 degrees
Acute angle = less than 90 degrees
Obtuse angle = more than 90 degrees
