Answer:
50.2
Step-by-step explanation:
we know the d is equate 10 and 6
so r for small circle is 3 and the large circle is 5
Ac=Al-As
Ac=π5²-π3²
Ac=25π-9π
Ac=16π=16*3.14=50.24
The life of a Radio Shack record player is normally distributed with a mean of 3 years and a standard deviation of 1 years. Radio Shack guarantees its record players for 2 years.
Find the probability that a record player will last less than 2 years?
Answer:
the probability that a record player will last less than 2 years is 0.1586
Step-by-step explanation:
Given that:
A mean which is normally distributed = 3
and a standard deviation = 1
The objective is to find that a record player will last less than 2 years
Let X be the random variable
i.e
From the standard normal tables :
P(X < 2) = 0.1586
Therefore; the probability that a record player will last less than 2 years is 0.1586
The translation applied to the triangle is:
T(x, y) → (x +4, y - 5)
Sp the correct option is the first one.
<h3>Which is the rule of the translation from GHI to G''H''I''?</h3>
To analyze the translation we only need to compare the coordinates of one of the vertices.
Let's see the vertex H.
The coordinates of H are (-4, 1)
The coordinates of H'' are (0, -4)
Then the translation is defined by the difference between these coordinates:
(0, -4) - (-4, -1) = (4, -5)
Then the translation here is:
T(x, y) → (x +4, y - 5)
So the correct option is the first one.
