Answer:
D
Step-by-step explanation:
2x - 15 = 2x - 15
whatever the x we take the left and right side are the same
Answer:
You get 12$ per B and 15$ per A. Thus, the answer is A) $282
Step-by-step explanation:
4A+4B=108
Divide by 4
A+B=27
Subtract B
A = 27 - B
3A+5B=105
Substitution
3(27-B)+5B = 105
Distribute
81-3B+5B=105
Combine like terms
81+2B=105
Subtract 81
2B=24
Divide by 2
B = 12
A = 15
14(15)+6(12)=x
210+72=x
282=x

"Simplifying a complex fraction" means Simplifying a complex fraction means to rewrite the fractions in the numerator and in the denominator with common denominators.
Step-by-step explanation:
A complex fraction is one where either the numerator or the denominator or both contains common a fraction.
There are two methods to simplify a complex fraction-
First Method
- We simplify the numerator until we have one single fraction.
- Then we simplify the denominator until we have one single fraction.
then we divide by multiplying the numerator by the reciprocal of the denominator.
- The end result is simplified
Second Method
- Firstly we find a common denominator of all the fractions in the numerator and all the fractions in the denominator .
- Then we multiply the number in the numerator and denominator of the complex fraction by a common denominator found in step 1.
- The result is simplified
Answer:
FALSE
Step-by-step explanation:
A binomial distribution is a data distribution where there are only 2 possible outcomes A or B.
If probability p is assigned to outcome A, and probability q is assigned to outcome B, then q = 1 - p.
In a binomial distribution, the mean is np, where n is the size of the sample, and the skewness is
As you can see, if p is different to 0.5 a binomial distribution is always skewed, and the skewness is independent of the sample size. Moreover, the sign of the skew only depends on the sign of 1 -2p
In this problem, we could have named:
<u>Event A</u> : The interviewed answered “YES” to the question “Do you start the day with a cereal breakfast?”
<u>Event B</u>: The interviewed answered “NO” to the question “Do you start the day with a cereal breakfast?”
In this case p = 0.8 and the skewness would be negative, so the distribution would be left skewed.
Answer:
-1/4
Step-by-step explanation:
We use the formula:
plugging in we have
Therefore our slope is -1/4
