Answer:
Option b
Step-by-step explanation:
Given that Mrs. Gomes found that 40% of students at her high school take chemistry
since each student is independent of the other, we can say
X no of students who take chemistry is binomial with p = constant proba = 0.40
n = no of trials = no of students surveyed =12
Required probability = prob atmost 4 students take chemistry
=
Substituting we get the cumulative probability
as
0.4382
round off to 0.438
Option b is correct answer
Answer:
the word similar means when to things are alike, it compares to congruent because congruent means thing are in harmony.
Things I would say are similar is a blanket and a sheet because they both provide coverage and warmth.
If I said things are similar it is because they are alike in meanings, or appearence.
I would use similar over congruent because congruent isn't a word you hear often. When you do hear it is mostly used to talk about angles and lines.

Answer:
The area of Ralph's dog pen is 2.05 times larger than the area of Ruth's dog pen.
Step-by-step explanation:
Given that the dog pen for Ruth's dog is 7 feet long and 6 / 1.3 feet wide, while her friend Ralph's dog pen is 14 feet long and 6 / 1.2 feet wide, to determine how many times larger is the area of Ralph's dog pen, the following calculation must be performed:
1/3 = 0.333
1/2 = 0.5
7 x 6.333 = X
44,333 = X
14 x 6.5 = X
91 = X
44,333 = 100
91 = X
91 x 100 / 44.333 = X
9,100 / 44,333 = X
205.26 = X
100 = 1
205.26 = X
205.26 / 100 = X
2.05 = X
Thus, the area of Ralph's dog pen is 2.05 times larger than the area of Ruth's dog pen.
