<span>C would be correct. Statistics and measures taken from raw data help the researcher understand whether or not they have a hypothesis that has held up under testing. Continual support for the hypothesis (and others of the like) can move the concept closer to the category of "theory" or "law," the gold standard in science research.</span>

According to the "January theory," if the stock market is up for the month of January, it will be up for the year. If it is down

Answer:

The required probability is 0.031918.

Step-by-step explanation:

Consider the provided information.

It is given that According to an article in The Wall Street Journal, this theory held for 22 out of the last 34 years.

Therefore n=34

The probability it is either up or down is 0.5.

Thus the value of p =0.5 and q = 0.5

Now calculate the probability

Let X is the number of years that theory held.

X has a binomial distribution with n=34 and p=0.5

$P(X=22)=\binom{34}{22}(0.5)^{22}(0.5)^{12}\\P(X=22)=\frac{34!}{22!\times 12!}(0.5)^{22}(0.5)^{12}\\P(X=22)=548354040\times 5.8207660913\times 10^{11}\\P(X=22)=0.0319184060208\\P(X=22)\approx0.031918$

Hence, the required probability is 0.031918.

∠A=5x+20

kogti [31]

Answer:

m∠A= 110°

Step-by-step explanation:

∠A+∠B=180°

5x+20+9x-92=180°

14x=180+92-20

14x/14=252/14

x=18

m∠A=5x+20

= 5(18)+20

=90+20

m∠A=110

hope it helps...

have a great day!!
