So we need to figure out how much he earns. So, if he takes two passengers and he charges a flat fee of $4.00 the he already has $8.00. So now we need to figure out how much money he gets from 4.8 miles and 7.3 miles. So he charges 2.25 miles per hour. So to get the first evening we have to multiply 4.8 times 2.25 to get $ 10.80. To get the next passenger we have to multiply 7.3 times 2.25. When you multiply 7.3 by 2.25 is 16.425. So you add the totals together and get $ 13.225 or 13.22
Answer:
Option C
Step-by-step explanation:
6x² +5x + 1
6x² + 3x + 2x + 1
3x(2x + 1) + 1(2x + 1)
(3x + 1)(2x + 1)
Answer:
Step-by-step explanation:
A geometric mean is just , where n is the number of terms.
i.e. Geometric mean of 5, 6, 7: there are three values, so the mean is
Make sure your decimals line up for addition and subtraction.
73.4581
+ 2.0033
--------------------
75.4614
Rounding to the nearest thousandth
75.461
we rounded down because the ten thousandths place is a 4 so thousandths place stays as is. If it were 5 or more it would have rounded up to a 2.
Answer:
And using the probability mass function we got:
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:
And using the probability mass function we got:
