Answer: B. False
Step-by-step explanation: Because you do
4x - 3 = 19
+3 +3 =4x = 22
You divide 4x divide by 4 and you get x
Then you divide 22 by 4 and get 5.5
So the answer is X = 5.5
5.50 x 3.87 equals 21.285. 21.285 rounded to the nearest cent is $21 dollars and 3 cents.
Answer:
Option D, 15 and 10
Step-by-step explanation:
<u>Step 1: Convert the words into an expression</u>
A number is 5 less than 2 times another number. Their sum is 25.
<em>2x - 5 = 25</em>
<em />
<u>Step 2: Solve for x</u>
2x - 5 + 5 = 25 + 5
2x / 2 = 30 / 2
<em>x = 15</em>

Answer: Option D, 15 and 10
Answer:
Binomial distribution,
n = 36 independent events,
p = 0.5 probability of success and of failure, as 1-p = p.
Mean of binomial distribution is np=18.
Variance is np(1-p)=9
Standard deviation is sqrt(variance)=3.
