Try this option (it is not the only way):
1. if to use for consecutive odd numbers: n; n+2; n+4 and n+6), then it is possible to write their sum in equation: n+n+2+n+4+n+6=40.
2. if to solve this equation: n=7 it means that 7 - the 1st number of the given sequence.
Using n=7 the 2d number of this sequence is n+2=9.
answer: 9.
Answer:
Since the shirt costs $43.76, and you paid the cashier $50.76; the change you will get back will be $7.
Step-by-step explanation:
$43.76-$50.76 =$7
Answer:
b. 42 people
Step-by-step explanation:
For each foreigner living in the U.S., there are only two possible outcomes. Either they are naturalized citizens, or they are not. The probability of a foreigner living in the U.S. not being a naturalized citizen is independent from other foreigners living in the U.S. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
"approximately 60% of foreign-born people who live in the U.S. are not naturalized citizens"
This means that
70 foreign-born people who live in the U.S
This means that
How many people would you expect to get that are not naturalized citizens?
So the correct answer is:
b. 42 people
Answer:
The factored difference is:
Step-by-step explanation:
Difference in non factored form:
To find the difference in non-factored form, we subtract the common terms. So
Greatest common factor:
Of the exponents: Between and , it is the one with the lowest exponent, so x.
Between 14, 20 and 10:
14 - 20 - 10|2
7 - 10 - 5
So 2
The gcf is 2x, which means that the factored expression is:
The factored difference is:
