Explanation:
This is because the value -16 is closest to 0, which represents sea level.
I recommend drawing out a vertical number line. Positive numbers are above 0, to indicate elevations above sea level. Negative numbers represent elevations below sea level.
The diagram is shown below. The diagram is not to scale because the red tickmarks shouldn't be equally spaced out; however, the order is correct, and that's all we need to worry about.
Note how -16 is the highest of the four choices, which makes it the closest to sea level. Also note how as you move further down, the negative values get larger in absolute value. It might be helpful to think of a thermometer.

11(9 + 6) will be the greatest common factor and the distributive property to rewrite this sum as 99 + 66.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
Given that,
⇒ 99 + 66
The highest common factor among both is 15
⇒ 11(9 + 6)
Hence " 11(9 + 6) will be the greatest common factor and the distributive property to rewrite this sum as 99 + 66".

Nathan has $40 in a savings account. The interest rate is 5% per year and is not
compounded. How much interest will he earn in 1 year?
Use the formulai = prt, where / is the interest earned, p is the principal (starting amount),
is the interest rate expressed as a decimal, and is the time in years.

Answers
Money with Nathan in his savings account = $40
Rate of interest per annum = 5%
We know that :
[tex]\color{hotpink}\tt \: simple \: interest \color{plum}= \frac{principal \times rate \times time}{100} [/tex]
In this case :
Principal = $40
Rate = 5%
Time = 1 year
Simple interest he will earn in 1 year :
[tex] =\tt \frac{40 \times 5 \times 1}{100} [/tex]
[tex] = \tt \frac{200}{100} [/tex]
[tex]\color{plum} =\tt\$ \: 2[/tex]
Amount = Principal + Interest
Amount Nathan has to pay at the end of one year :
[tex] = \tt40 + 2[/tex]
[tex]\color{plum} =\tt \$42[/tex]
Thus, at the end of 1 year Nathan has to pay $42.
Therefore, simple interest Nathan will earn in 1 year = $2

3. Jalen is a lifeguard at a public swimming pool and is planning to string
flags across both diagonals of the rectangular pool. He knows the
dimensions of the pool are 50 meters by 25 meters.
What value represents the length of flag string Jalen will need to reach
across the diagonals of the pool?
Answers
Answer:
[tex]Flag = 55.90m[/tex]
Step-by-step explanation:
Given
[tex]Length = 50m[/tex]
[tex]Width = 25m[/tex]
Required
Determine the length of the flag
Because the flag crosses through opposite diagonals of the pool. Its length is the length of the diagonal of the pool.
This is calculated using Pythagoras theorem.
[tex]Flag^2 = Length^2 + Width^2[/tex]
Substitute values for Length and Width
[tex]Flag^2 = 50^2 + 25^2[/tex]
[tex]Flag^2 = 2500 + 625[/tex]
[tex]Flag^2 = 3125[/tex]
Take positive square root of both sides
[tex]Flag = \sqrt{3125[/tex]
[tex]Flag = 55.90m[/tex]
Hence, the length of the flag is approximately 55.90m

A study was conducted to determine whether there were significant differences between medical students admitted through special programs (such as retention incentive and guaranteed placement programs) and medical students admitted through the regular admissions criteria. It was found that the graduation rate was 92.4% for the medical students admitted through special programs.
Required:
a. If 12 of the students from the special programs are randomly selected, find the probability that at least 11 of them graduated.
b. If 12 of the students from the special programs are randomly selected, find the probability that exactly 9 of them graduated.
c. Would it be unusual to randomly select 12 students from the special programs and get exactly 9 that graduate?
Answers
Answer:
a) 0.7696 = 76.96% probability that at least 11 of them graduated.
b) 0.0474 = 4.74% probability that exactly 9 of them graduated.
c) Since 9 is less than 2.5 standard deviations from the mean, it would not be unusual.
Step-by-step explanation:
For each student, there are only two possible outcomes. Either they graduated, or they did not. Each student is independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Unusual outcome:
An outcome in the binomial distribution is unusual if it is more than 2.5 standard deviations from the mean.
92.4% for the medical students admitted through special programs.
This means that [tex]p = 0.924[/tex]
a. If 12 of the students from the special programs are randomly selected, find the probability that at least 11 of them graduated.
This is [tex]P(X \geq 11)[/tex] when [tex]n = 12[/tex]. So
[tex]P(X \geq 11) = P(X = 11) + P(X = 12)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 11) = C_{12,11}.(0.924)^{11}.(0.076)^{1} = 0.3823[/tex]
[tex]P(X = 12) = C_{12,12}.(0.924)^{12}.(0.076)^{0} = 0.3873[/tex]
[tex]P(X \geq 11) = P(X = 11) + P(X = 12) = 0.3823 + 0.3873 = 0.7696[/tex]
0.7696 = 76.96% probability that at least 11 of them graduated.
b. If 12 of the students from the special programs are randomly selected, find the probability that exactly 9 of them graduated.
This is P(X = 9). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 9) = C_{12,9}.(0.924)^{9}.(0.076)^{3} = 0.0474[/tex]
0.0474 = 4.74% probability that exactly 9 of them graduated.
c. Would it be unusual to randomly select 12 students from the special programs and get exactly 9 that graduate?
The mean number of students expected to graduate is:
[tex]E(X) = np = 12*0.924 = 11.09[/tex]
The standard deviation is
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{12*0.924*0.076} = 0.92[/tex]
11.09 - 2.5*0.92 = 8.79
This means that anything below 8.79 is unusual, so, since 9 is less than 2.5 standard deviations from the mean, it would not be unusual.

-3eˣx²-11eˣx-6eˣ
Step-by-step explanation:
I'm going to go by the picture and not what you wrote in your title.
To find the derivative of this we have to apply the product rule
(a*b)'=
a'*b+a*b'
We plug in our numbers and get
(-3x²+x-2)'*eˣ+(-3x²+x-2)*eˣ'
Now we can evaluate the derivatives and simplify
(-3x²+x-2)'= -6x+1
eˣ'=eˣ
which means we have
(-6x+1)*eˣ+(-3x²+x-2)*eˣ
Simplify
-6xeˣ+eˣ-3x²eˣ+xeˣ-2eˣ
Combine like terms
-3x²eˣ-5xeˣ-eˣ
Now we just need to find the derivative of this
We can apply the same product rule as we did before
(-3x²eˣ)'
Let's start by factoring out the -3 to get
-3(x²eˣ)'
which is equal to
-3(x²eˣ'+x²'eˣ)
Compute this and get
-3(x²eˣ+2xeˣ)= -3x²eˣ-6xeˣ
Now let's find the derivative of the second part
(-5xeˣ)'
-5(x'eˣ+xeˣ')
-5(eˣ+xeˣ)
-5eˣ-5xeˣ
Which means we have
(-3x²eˣ-6xeˣ)+(-5eˣ-5xeˣ)-eˣ
Combine like terms and get
-3eˣx²-11eˣx-6eˣ

What is the probability of drawing an even numbered card from a standard deck of shuffled cards?
A) 20/52
B) 25/52
C) 30/52
D) 35/52
Answers
Answer:
Prob = 20/52
Step-by-step explanation:
There are 5 even number cards per suit: 2, 4, 6, 8, and 10.
and there are 4 suits in a deck, so the total of the even number card events is 5 * 4 = 20
Given that the deck has 52 cards total, then the probability of drawing an even numbered card is the number of successes (20) divided the number of total cards (52) This gives:
Prob = 20/52
which agrees with answer A) in your list.
