Answer:
11/18
Step-by-step explanation:
The desired probability is the sum of ...
... (probability of choosing a coin) × (p(heads) on that coin)
Since the coins are chosen at random, we assume the probability of choosing a given coin is 1/3. Then ...
... p(heads) = (1/3)·(1/2) + (1/3)·1 + (1/3)·(1/3) = 1/6 + 1/3 + 1/9 = (3 +6 + 2)/18
... p(heads) = 11/18
Answer:
see the explanation
Step-by-step explanation:
we know that
If the absolute value of the scale factor is less than 1, then the dilation produces a contraction of the original image
If the absolute value of the scale factor is greater than 1, then the dilation produces an expansion of the original image
so
<u><em>Verify each value</em></u>
1) -4


therefore
The dilation produces an expansion of the original image
2) 0.25


therefore
The dilation produces a contraction of the original image
3) -2/3


therefore
The dilation produces a contraction of the original image
4) 2.3


therefore
The dilation produces an expansion of the original image
Answer:
35/100
Step-by-step explanation:
it would be 7/20 because both the numerator and denominator are divisible by the number 5.
Step-by-step explanation:
The function is as follows :

We need to find the zeroes of the function in the simplest radical form.The zero of the above function is given by :

Here,
b = 5
a = 1
c = 5
So,

Hence, the correct option is (c).
Answer:
Both of them are Non-Proportional since none are touching 0. I'm not sure if you're looking for Proportionality.
