solve for x.
2x + 15
5x - 12
Answer:
x = 9
Step-by-step explanation:
2x + 15 = 5x - 12 (since it is parallel)
15 + 12 = 5x - 2x
27 = 3x
x = 9

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.
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.

solve each function for f(1) please i need help asap
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.

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
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

TW is the midsegment of the trapezoid UVXY
=> 2TW = XY + UV
=> 2(z - 2) = 4z - 34 + z
=> 2z - 4 = 5z - 34
=> 5z - 2z = 34 - 4
=> 3z = 30
=> z = 10
Answer: z = 10

Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the Quadrilateral. Show your work. ( Please do not recopy another students answers on Brainly Or Any Other Websites. You'll be reported if you do. (Will Mark Brainliest if answered correctly.
Answer:
Shown Below.Explanation:
opposite angles in a quadrilateral sum up to 180°
total interior angles in a quadrilateral is 360°
solve for x:
x - 2 + x + 2 = 180°
2x = 180°
x = 90°
solve for each angle:
1st
x + 2
90° + 2 = 92°
2nd
x - 2
90° - 2 = 88°
3rd
x - 10
90° - 10° = 80°
4th
360° - 80° - 88° - 92° = 100°
The triangles below are similar.

y = [?]
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

Answer:
NO
Step-by-step explanation:
A scalene triangle has no sides equal. This triangle has two sides equal with 13 inches. This triangle is isosceles.
Assume that females have pulse rates that are normally distributed with a mean of 78 beats per minute and a standard deviation of 12.5 beats per minute find the probability of a pulse rate between 61 beats per minute and 72 beats per minute
Answer:
61 beats = 4.88
72 beats = 5.76
Step-by-step explanation:
Firstly,you have to divide 61 to 12.5 then you can get 4.88. After that, you must divide 72 to 12.5 then you can get 5.76. Hope this will help you!
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?
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.
