The answer is A) x = 9
We know this because every four sided figure has angles that measure up to 360. So we can subtract all of the angles and then use the remaining angle to solve the problem.
360 - 90 - 90 - 99 = 81.
So with the remaining angle being 81, we can solve for x.
x^2 = 81
x = +/-9
Since +9 is the only answer that makes sense in this case, x = 9.
Answer:
0.099, 0.969,0.87,8.3.1.063
Step-by-step explanation:
Let X be the left handed people in the sample of 10 people selected.
X is binomial with n=10 and p = 0.13
a) the probability that there are exactly 3 lefties in the group
=
b) the probability that there are at least 3 lefties in the group
=
Now Y number of right handers is binomial with n =10 and p = 0.87
c) the expected number of right-handers in the group.
d) the standard deviation of the number of right-handers in the group
=
Answer:
The correct options are C and D
C. A translation of 5 units up
D. A reflection about the x-axis
Step-by-step explanation:
We have been given as function of the graph:
f(x) = x²
Which is transformed into the function
g(x) = -(x-2)² + 5
Consider the graph of y = x²
To convert it into the graph of given transformed function.
First reflect the graph over x-axis, the equation becomes
y = -(x)²
Then translate the graph 2 units to the right
y = -(x - 2)²
Then translate the graph 5 units up.
y = -(x - 2)² + 5
Thus, the correct statements are C and D
