We are given with a rectangle whose length is 27 miles , and breadth is (3y + 1) miles and we are asked to find it's area . As , we know that , the area of a rectangle with Length and Breadth , L and B is given by Area = L × B respectively . Now , using this same formula in our question we have ;
[tex]{:\implies \quad \sf Area=27\times (3y+1)}[/tex]
[tex]{:\implies \quad \sf Area=27\times 3y + 27\times 1}[/tex]

Answer:
it's 11 and x is 12
Answer:
y = 15
Step-by-step explanation:
since the triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{y}{33}[/tex] = [tex]\frac{10}{22}[/tex] ( cross- multiply )
22y = 330 ( divide both sides by 22 )
y = 15

How much did you deposit at the end of each month into an investment account to pay 6.5% compounded monthly to have $3 million when you retire and 37 years
Answers
Answer:
$272559.70
Step-by-step explanation:
So, let's start with what we know
This problem should be solved with the formula
A = P ( 1 + r/n)^nt
The variable A is the final amount
A = 3000000
This is the amount we want to achieve
The variable P is the principle, the amount of money you put in a bank to earn interest
We have to solve for this value
The variable r is the interest rate
r = 0.065
Note: I converted the percent to a decimal, so we can use it in the formula
The variable n is the amount of times interest is compounded
n = 12
The interest is compounded monthly in a year, so 12 times
The variable t is the amount of time you have to earn the interest
t = 37
So, let's solve for the value P with the values we know
3000000 = P ( 1 + 0.065/12)^(12x37)
3000000 = P(11.0067628047)
3000000 / 11.0067628047 = P(11.0067628047) / 11.0067628047
272559.702905 = P
P = 272559.70
Note: I rounded to the nearest cent, since there isn't a value of USD lower than 1 cent.
So, there you have it, a principle of 272559.70 will get you 3000000 in 37 years given that interest is compounded monthly at 6.5% interest rate

solve each function for f(1) please i need help asap
Answers
Answer:
a. 2/3
b. [tex]\sqrt{2}[/tex]
c. 3
d. 5
e. 2
f. Undefined
Step-by-step explanation:
a. [tex]f(x)=\frac{|x-3|}{x+2}[/tex]
To find f(1), plug in 1 where every x is in the equation
[tex]f(1)=\frac{|1-3|}{1+2}=\frac{|-2|}{3}=\frac{2}{3}[/tex]
b. [tex]f(x) = \sqrt{x+1}[/tex]
[tex]f(1) = \sqrt{1+1}=\sqrt{2}[/tex]
c. [tex]f(x) = x^2+5x-3[/tex]
[tex]f(1) = (1)^2+5(1)-3=1+5-3=6-3=3[/tex]
d. [tex]f(x)=\frac{2x+3}{x}[/tex]
[tex]f(1)=\frac{2(1)+3}{1}=\frac{5}{1}=5[/tex]
e. [tex]f(x) = |2x-4|[/tex]
[tex]f(1) = |2(1)-4|=|2-4|=|-2|=2[/tex]
f. [tex]f(x)=\frac{7-2x}{x-1}[/tex]
[tex]f(1)=\frac{7-2(1)}{1-1}=\frac{5}{0}[/tex]
This equation is undefined when x=1 because 0 is the denominator of the fraction.

Employees at a hospital take the temperature of every one of its more than 1,000 patients who visit the emergency room. The body temperatures of these patients follow a normal distribution similar to this:
Suppose that the hospital takes a random sample of 16 patients and calculates the sample mean temperature for those patients.
What will be the shape of the sampling distribution of the sample mean temperature?
Answers
Answer:
Approximately Normal
Step-by-step explanation:
Since we're given a normally distributed population, the sampling distribution of the sample means will also be normally distributed, even when the sample size is small.

In the Country A legal system, a defendant is presumed innocent until proven guilty. Consider a nullhypothesis, H0, that the defendant is innocent, and an alternative hypothesis, H1, that the defendant is guilty. A jury has two possible decisions: Convict the defendant (i.e., reject the nullhypothesis) or do not convict the defendant (i.e., do not reject the null hypothesis). Explain the meaning of the risks of committing either a Type I or Type II error in this example.
Answers
Using error concepts, it is found that in this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.
What are Type I and Type II errors?Type I: Rejection of a true null hypothesis. The null hypothesis is true, but from a sample, you get enough evidence to reject.Type II: Non-rejection of a false null hypothesis. The null hypothesis is false, but from a sample, you do not get enough evidence to reject.Hence:
In this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.
