Answer:
The equation of the line in slope intercept form is y=1/3x+2
Step-by-step explanation:
Answer:
B
Step-by-step explanation: The answer is B because the dilation is showing that the triangle is getting bigger therefore the answer is going to be 1 or more
Answer:
slope = - 3
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (- 6, 6) and (x₂, y₂ ) = (- 3, - 3)
m = = = = - 3
Answer:
The standard deviation of the number of haunted houses in a large city is 3.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval, which is the same as the variance.
According to ghost hunters, large cities have, on average, 9 haunted houses each.
This means that
a) What is the standard deviation of the number of haunted houses in a large city?
Square root of the variance, so:
The standard deviation of the number of haunted houses in a large city is 3.
Answer:
5 cm
Step-by-step explanation:
ΔABC is equilateral, so BC = AB = 5 cm.
____
AO is the perpendicular bisector of BC and the angle bisector of angle A, so ∠OAC = ∠OAB = 30°. Then vertex angle BAC of isosceles triangle ABC is 60°, which means all angles in the triangle are 60° and the triangle is equilateral.
