Step-by-step explanation:
There are 14 marbles in total, of which 5 of them are red. Therefore, the probability that the first marble she chooses is red is [tex]\frac{5}{14}[/tex].
Since she does not replace the marble, there are now 13 marbles in total, of which 4 are red (she drew one of the red marbles on her first draw). Therefore the probability of her drawing a red marble on her second draw is [tex]\frac{4}{13}[/tex], assuming she draws a red marble on the first draw.
Thus, the probability she draws a red marble on both draws is [tex]\fbox{$\mathrm{A.} \: \frac{5}{14}\cdot \frac{4}{13}$}[/tex].

Simplify the expression by combining like terms 2w+4w+8w? whats the answer
Answers
Explanation: In this expression, +2w, +4w, and +8w are called terms and the numbers in front of the variables, +2, +4, and +8 are called coefficients.
Because the variables are identical,
the three terms in this problem are called like terms.
They can be added together by adding their coefficients.
Since 2 + 4 + 8 is 14, 2w + 4w + 8w is 14w.

Answer:
The best course grade your friend can earn is 0.867 = 86.7%.
The minimum score would your friend would need on the final to earn a 75% for the course is of 0.61 = 61%.
Step-by-step explanation:
This is a weighed average problem, in which we multiply each grade by its weight.
We have that:
In 70% of the course, the friend has a grade of 81%.
In the other 30%, he will have x.
What is the best course grade your friend can earn?
This will happen if he earns 100% = 1 on the final test. So
[tex]G = 0.7*0.81 + 0.3*1 = 0.867[/tex]
The best course grade your friend can earn is 0.867 = 86.7%.
What is the minimum score would your friend would need on the final to earn a 75% for the course?
This is x, when the grade is 0.75. So
[tex]0.75 = 0.7*0.81 + 0.3x[/tex]
[tex]0.3x = 0.75 - 0.7*0.81[/tex]
[tex]x = \frac{(0.75 - 0.7*0.81)}{0.3}[/tex]
[tex]x = 0.61[/tex]
The minimum score would your friend would need on the final to earn a 75% for the course is of 0.61 = 61%.

Answers
The probability that the numbers on the broken calculators are at least 16 will be 0.9997.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
There are 30 calculators numbered 1-30 in a case. If 4 of the calculators are broken.
Then the probability that the numbers on the broken calculators are at least 16 will be
Number of ways to get a sum less than 16 = 1234, 1235, 1236, 1237, 1238, 1239, 2345, 2346 = 8
Probability = 1 – 8 / (³⁰C₄) = 1 – 8/27405 = 0.99970808246

The number of trees in a rainforest decreases each month by 0.5%. The forest currently has 2.5 billion trees. Write an expression to represent how many trees will be left in 10 years. Then, evaluate the expression.
Answers
The number of the trees that will be left after 10 years will be 2.3 billions.
What is the percent decrease?A rate of change is negative when the output decreases as the input increases or when the output increases as the input decreases.
Given that, the number of trees in a rainforest decreases each month by 0.5%. The forest currently has 2.5 billion trees.
The expression will be:
A = P(1-r)ⁿ
A = final amount
P = initial amount
r = rate
n = time
Therefore,
A = 2500000000(1-00.5)¹⁰
A = 2500000000(0.995)¹⁰
A = 2300000000
Hence, the number of the trees that will be left after 10 years will be 2.3 billions.
