Answer:
Positive 8
Step-by-step explanation:
Since they're both negative numbers and it went from -9 to -1, you had to have added a positive number to get a lesser negative number. To put it simply, if you were to subtract 8 from 9, you'd get 1.
Answer:
644ft^2
Step-by-step explanation:
Area of triangle=1/2bh
Area of square=l*l
so we have;
4 triangles with a base of 14ft and height of 16ft and 1 square with l=14ft
AreaTriangle=1/2(14ft)(16ft)=112ft*4=448ft^2
AreaSquare=14ft*14ft=196ft^2
Area Total=448ft+196ft=644ft^2
Answer:

Step-by-step explanation:
so first we need to find the height so by splitting the isosceles triangle into two right-angled triangles and then applying Pythagoras' Theorem to one of them.





We now know the height of the triangle and can use this to go back and find the area of the isosceles triangle.
area of triangle =
x base x height
area of triangle =
x 10 x 12
area of triangle = 60
Answer:
the 0,2 does beautiful as it comes
Answer:
e) 0.14
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a driver does not have a valid driver's license.
B is the probability that a driver does not have insurance.
We have that:

In which a is the probability that a driver does not have a valid driver's license but has insurance and
is the probability that a driver does not have any of these things.
By the same logic, we have that:

We start finding these values from the intersection.
4% have neither
This means that 
6% of all drivers have no insurance
This means that
. So



12% of all drivers do not have a valid driver’s license
This means that 
So



The probability that a randomly selected driver either fails to have a valid license or fails to have insurance is about

So the correct answer is:
e) 0.14
