Slope intercept form is
where
is the slope
and
is the y-intercept
they give us that the slope is 2
so our
then to find
, we temporarily plug in the point they gave us for x and y
so
and solve for
3 = 2 + b
1 = b
so our
put this together and we get
as our answer
Since the problem is quite vague because the number of
choice per question is not written here. I’ll just put for 4 choices and 5
choices each.
To compute for the 5 choices each:
Mean = np = 20 (1/5) = 4
Standard deviation = sqrt(npq) = sqrt (4*(4/5) = 1.79
To compute for the 4 choices each:
Mean = np = 20 (1/4) = 5
Standard deviation = sqrt(npq) = sqrt (5*(4/5) = 2
Answer:
a. it will have more spread
for prepworks users :)
Answer: 120 cm²
Step-by-step explanation:
Let's start by finding the area of one triangle
The formula for finding the area of a triangle is 
Where
A is the area
h is the height (5 for this)
and b is the base (4 for this)
Let's sub in our values and solve.
Since there are 12 triangles in the shape we must multiply our area for one triangle by 12 to find the total area of the shape
12×10=120
88.23%
Simply plug 15/17 into you calculator
and it will give you a decimal, in this case it should be .88235294...
simply move the decimal back to placements and you should have
88.235294... thats still a lot of numbers so just reduce it to 2 places after the decimal and add a percent sign
88.23%
and your done :) this works for any similar problems
I hope this helps
