The population of coyotes in the northwestern portion of Alabama is given by the formula p (t )equals (t squared plus 100 )ln (t plus 2 ), where t represents the time in years since 2000 (the year 2000 corresponds to t equals 0 ). Find the rate of change of the coyote population in 2002 (tequals2).
Answer:
The rate of change of the Coyote population in 2002 is 32
Step-by-step explanation:
Given the formula for the population of a Coyotes in the Northwestern portion of Alabama, we are to calculate rate of change of the Coyote population in the year 2002 where t = 2
The formula is given as;
P(t) = (t^2 + 100) ln (t + 2)
The rate of change refers to the first integral of the formula;
Thus we need to calculate this by the use of product formula;
The first differential of t^2 + 100 is 2t
while that of ln(t + 2) is 1/(t + 2)
P’(t) = 2t(ln (t+2)) + (t^2 + 100) (1/t+2)
Now, we substitute 2 for the value of t here.
P’(2) = 2(2)( ln (2 + 2) + (2^2 + 100)(1/(2+2))
P’(2) = 4 ln 4 + 104(1/4)
P’(2) = 4ln 4 + 26
P’(2) = 5.55 + 26 = 31.55 which is approximately 32

What is a rational and irrational number?A Rational Number is a number of the form p/q, p & q are integers, and q ≠ 0. An irrational number is all real numbers except rational numbers i.e. it is a non-repeating and non-terminating decimal number or it can not be expressed in a ratio of two integers.
Further, natural numbers can be rational numbers. Also, all repeating and terminating decimals are rational.
The difference between a rational number and an irrational number is always an irrational number. For example:
2 - √3 is always an irrational number where 2 is rational and √3 is an irrational number.
Hence addition and subtraction of rational and irrational numbers is always an irrational number.

Answer:
Option (2)
Step-by-step explanation:
Option (1).
Time taken by Tina to walk = 56 minutes
Time taken by her sister to walk the same distance = x minutes
If both the sisters take the same time to walk, then
x = 56 minutes
Option (2).
Let the height of Tina = x inches
and the height of her brother = 56 inches
if Tina is shorter than her brother then,
x < 56 inches
Option (3).
Tina's dog weighed two months ago = 56 pounds
If the dog gained the weight in two months then weight before 2 months will be less than the present weight.
Let the weight of her dog is x pounds now,
x > 56 pounds
Option (4).

How many percent is the change in the price, if:The price was $160 and now it is $40?
Answer:
75% reduction
Step-by-step explanation:
The price dropped by $120. As a percentage of the original price, that is ...
-$120/$160 × 100% = -75%
The price changed by -75%.
Answer:
75% decrease.
Step-by-step explanation:
The original price is $160 and we went to $40.
That means the price got reduced by $120 in the process.
$120/$160 = 0.75 = 75%.
So in other words, we lost 75% of the price ($120) and got left with 25% of the price ($40).

Eric's average income for the first 4 months of the year is $1,450.25, what must be his average income for the remaining 8 months so that his average income for the year is $1,780.75?
Answer:
Average income for the remaining 8 months = $2,111.25
Step-by-step explanation:
Given:
Average income of 4 months = $1,420.25
Annual average income = $1,780.75
Find:
Average income of 8 months
Computation:
⇒ Annual average income = [Average income of 4 months + Average income of 8 months] / 2
⇒ $1,780.75 = [$1,420.25 + Average income of 8 months] / 2
⇒ $3,561.5 = $1,420.25 + Average income of 8 months
⇒ Average income of 8 months = $3,561.5 - $1,420.25
Average income of 8 months = $2,111.25

If your target number of calories is 1200 per day to lose weight, but you are consuming 1100 calories per day, then your target is what percent of the calories you are consuming?
Answer:
109.090909....%(goes on indefinitely)
Step-by-step explanation:
If you are only consuming 1100, and your goal is 1200, as a percentage your target is 1200/1100 of what you are consuming. That simplifies to 12/11, which would mean as a percentage, your target is 109.0909090909...% of what you are consuming.

A machine in the student lounge dispenses coffee. The average cup of coffee is supposed to contain 7.0 ounces. A random sample of seven cups of coffee from this machine show the average content to be 7.4 ounces with a standard deviation of 0.70 ounce. Do you think that the machine has slipped out of adjustment and that the average amount of coffee per cup is different from 7 ounces
Answer:
[tex]t=\frac{7.4-7}{\frac{0.7}{\sqrt{7}}}=1.512[/tex]
The degrees of freedom are
[tex]df=n-1=7-1=6[/tex]
And the p value for this case is:
[tex]p_v =2*P(t_{(6)}>1.512)=0.181[/tex]
The p value is a higher value and using a significance levels of 5% or 10% we see that the p value is higher than the significance level and then we FAIL to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is different from 7 ounces.
Step-by-step explanation:
Information provided
[tex]\bar X=7.4[/tex] represent the sample mean
[tex]s=0.7[/tex] represent the sample standard deviation
[tex]n=7[/tex] sample size
[tex]\mu_o 7[/tex] represent the value to verify
t would represent the statistic
[tex]p_v[/tex] represent the p value
System of hypothesis
We want to verify if the average amount of coffee per cup is different from 7 ounces, the system of hypothesis would be:
Null hypothesis:[tex]\mu = 7[/tex]
Alternative hypothesis:[tex]\mu \neq 7[/tex]
The statistic is given by:
[tex]t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}[/tex] (1)
Replacing the info given we got:
[tex]t=\frac{7.4-7}{\frac{0.7}{\sqrt{7}}}=1.512[/tex]
The degrees of freedom are
[tex]df=n-1=7-1=6[/tex]
And the p value for this case is:
[tex]p_v =2*P(t_{(6)}>1.512)=0.181[/tex]
The p value is a higher value and using a significance levels of 5% or 10% we see that the p value is higher than the significance level and then we FAIL to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is different from 7 ounces.

4. Automobile policies are separated into two groups: low-risk and high-risk. Actuary Rahul examines low-risk policies, continuing until a policy with a claim is found and then stopping. Actuary Toby follows the same procedure with high-risk policies. Each low-risk policy has a 10% probability of having a claim. Each high-risk policy has a 20% probability of having a claim. The claim statuses of polices are mutually independent. Calculate the probability that Actuary Rahul examines fewer policies than Actuary Toby.
Answer:
Step-by-step explanation:
for n ∈ N
Since Actuary Rahul examines low-risk policies, continuing until a policy with a claim is found and then stopping.
∴ the probability that Actuary Rahul examines exactly n policies
[tex](0.9)^{n-1}.(0.1)---(1)[/tex]
the probability that Actuary Toby examines more than exactly n policies

Given that policies are actually independent
∴ the probability that the event (1) and (2) happens simultaneously is
[tex](0.9)^{n-1}*(0.1)*(0.8)^n[/tex]
∴ the probability that Actuary Rahul examines fewer policies than Actuary Toby
[tex]\sum ^\infty _{n=1} (0.9)^{n-1}*(0.1)*(0.8)^n\\\\=(\frac{0.1}{0.9} \sum ^\infty _{n=1}(0.72)^n\\\\=\frac{1}{9} (\frac{0.72}{0.28} )\\\\=\frac{2}{7} \\\\=0.2857[/tex]
