Answer:

P (HHH) = 1/8

Step-by-step explanation:

We want the probability of HHH

P(HHH) = P (heads and Heads and heads)

When we have an and, we multiply the probability

P(heads 1st time) * p(heads 2nd time) * P (3rd time)

The probability of a heads is 1/2

1/2 * 1/2 * 1/2

P (HHH) = 1/8

An expression is shown

PSYCHO15rus [73]

Answer:

Step-by-step explanation:

Adding the expressions in the numerator, we get:

6·10^(-5).

Then the given fraction appears like:

6·10^(-5)

-------------

3·10^7

First, we reduce 6/3, obtaining 2:

10^(-5)

2 -------------

10^(7)

Since the bases are the same, we can rewrite these exponentials with that base (10) and single exponent 12, which is the sum of 5 and 7 and is in the denominator:

---------

10^12

This matches the second possible answer choice.

115% of what number is 120?

antiseptic1488 [7]

115% is the same as 1.15
some number = x

115% of some number is 120
1.15 of x is 120
1.15 * x = 120
$\frac{1.15*x}{1.15} = \frac{120}{1.15}$
x = 104.3478
x ≈ 104.3

Hope this helps! :)
