X • (x-5) Add up the last 2 terms, pulling out common factors : 1 • (x-5) Step-5 : Add up the ... Step 2 :Theory - Roots of a product ... In other words, we are going to solve as many equations as there are terms in the product
I hope this help
We know that
sin 64°= cos (x)
64° and x-------> are complementary angles
64°+x=90°
then
x=90-64----------> 26°
so
sin 64°=cos 26°
the answer is
x=26°
Answer:
The chance that there will be exactly 2 heads among the first five tosses and exactly 4 heads among the last 5 tosses is P=0.0488.
Step-by-step explanation:
To solve this problem we divide the tossing in two: the first 5 tosses and the last 5 tosses.
Both heads and tails have an individual probability p=0.5.
Then, both group of five tosses have the same binomial distribution: n=5, p=0.5.
The probability that k heads are in the sample is:

Then, the probability that exactly 2 heads are among the first five tosses can be calculated as:

For the last five tosses, the probability that are exactly 4 heads is:

Then, the probability that there will be exactly 2 heads among the first five tosses and exactly 4 heads among the last 5 tosses can be calculated multypling the probabilities of these two independent events:

Answer:
A= 335.5 units squared
Step-by-step explanation:
B. 17.16 represents a credit of $17.16; "credits" mean that you're receiving something, so it's added. A is incorrect because it shows the money being taken away and that isn't what a credit does. C and D aren't even the same amount of money in the question, so they aren't your answer either.
