Answer:
Please rate as brainliest.
Step-by-step explanation:
The Moon exerts its force of gravity; since it's smaller and lighter than Earth, we would discover we weigh around a sixth of our weight on Earth if we could weigh ourselves on it. One could ask why the Moon doesn't fall on Earth as an apple from the tree.
Answer:
The parameters of this exponential distribution is
=
.
Step-by-step explanation:
We are given that the random variable X is known to be exponentially distributed and let X be the time it takes for a person to choose a birthday gift, where X has an average value of 27 minutes.
<u><em>So, X = time it takes for a person to choose a birthday gift</em></u>
The probability distribution function of exponential distribution is given by;
where,
= parameter of distribution.
Now, the mean of exponential distribution is =
which is given to us as average value of 27 minutes that means
.
So, X ~ Exp(
) .
Therefore, the parameter of this exponential distribution is
.
Yes, because 1+3 is 4*2 is 8, and and on the other side 1+1 is 2*5 is 10 the 10-2 is 8 so 8=8
Answer:
x = 7
Step-by-step explanation:
Because the points are collinear:
AB + BC = AC
We'll plug in the expressions in terms of x.
(-1 + 2x) + (11) = (3x + 3)
And solve for x. Combine like terms on the left
2x + 10 = 3x + 3
Subtract 3 on both sides
2x + 7 = 3x
Subtract 2x on both sides
7 = x
