Answer:
0.03593
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 17,340
μ is the population mean = 15,000
σ is the population standard deviation = 1300
z score:
z = 17340 - 15000/1300
z =1.8
Probability value from Z-Table:
P(x<17340) = 0.96407
P(x >17340) = 1 - P(x<17340)
= 1 - 0.96407
= 0.03593
The probability that the life span of the monitor will be more than 17,340 hours is 0.03593

Answer and Step-by-step explanation:
[tex]5^{2} * 5^{-5} \\[/tex] is [tex]\frac{1}{125}[/tex]
This is because 5 times 5 is 25.
5 to the negative 5th is 1/3125.
Multiply these together and you get 1/125.

Arrange the expressions in ascending order of their values when x = -2.
1-x^2/1-2x
x^2-1/1-2x
2x^2+x/2
3x^2+1/2(x-1)
Step-by-step explanation:
Option (1)
[tex]\dfrac{1-x^2}{1-2x}[/tex]
Put x = -2, let the value is y such that,
[tex]y=\dfrac{1-(-2)^2}{1-2(-2)}\\\\=\dfrac{1-4}{1+4}\\\\=-0.6[/tex]
Option (2)
[tex]\dfrac{x^2-1}{1-2x}[/tex]
Put x = -2, let the value is y such that,
[tex]y=\dfrac{(-2)^2-1}{1-2(-2)}\\\\=\dfrac{4-1}{1+4}\\\\=0.6[/tex]
Option 3)
[tex]2x^2+\dfrac{x}{2}[/tex]
Put x=-2 such that,
[tex]y=2(-2)^2+\dfrac{(-2)}{2}\\\\=7[/tex]
Option (4)
[tex]3x^2+\dfrac{1}{2(x-1)}[/tex]
Put x =-2 such that,
[tex]y=3(-2)^2+\dfrac{1}{2((-2)-1)}\\\\=11.83[/tex]
Ascending values : -0.6,0.6,7,11.83
or
[tex]\dfrac{1-x^2}{1-2x}[/tex] < [tex]\dfrac{x^2-1}{1-2x}[/tex] < [tex]2x^2+\dfrac{x}{2}[/tex] < [tex]3x^2+\dfrac{1}{2(x-1)}[/tex]

Answer:
x is 2 and y is 2✓3
Step-by-step explanation:
this is because of the 30 60 90 theorem
so 1 is n
and x has to be 2n so it is 2
and y is n√3 so it's 2√3
Answer:
x = 2 , y = √3
Step-by-step explanation:
In right angled Δ, the leg against of 30° angle equals half of length of hypotenuse ⇒ x = 2 and y = √(4 - 1) = √3

Alex placed a classified ad in the local newspaper to sell his used Nissan Sentra. He plans to write a 9 line ad. The newspaper charges $17.50 for the first three lines (total) and then $8.25 for each extra line. How much will Alex pay for the ad?
Answer:
$67 total
Step-by-step explanation:
9-3= 6
6(8.25)= 49.50
49.50+17.50= $67
Answer:
$67.00
Step-by-step explanation
17.50 (first 3 lines) + 8.25 (for each of the 6 lines left)
17.50 + (8.25*6) =
17.50 + 49.50 =
67

An account is opened with an initial deposit of $700 and earns 3.3% interest compounded semi-annually. What will the account be worth in 3 years? Round your answer to the nearest cent.
Answer:
772.22
Step-by-step explanation:
A=$700(1+0.0332)2(3). Simplify using the order of operations: A=$700(1.0165)6=$700(1.103174712)≈$772.22.
Travis made a business trip of
195.5 miles. He averaged
53 mph for the first part of the trip and
58 mph for the second part. If the trip took
3.5 hours, how long did he travel at each rate?
Answer:
At 53 mph, he traveled for 1.5 hours
At 58 mph, he traveled for 2 hours
Step-by-step explanation:
Mathematically;
distance = speed * time
let the time for the first part of the trip be x hours and the second part be y hours
Total hours is 3.5
So therefore;
x + y = 3.5 ••••••••(i)
Now let’s work with the rate
53 mph for x hours = 53 * x = 53x miles
58 mph for y hours = 58 * y = 58y miles
Adding both;
53x + 58y = 195.5 miles ••••••••(ii)
We have two equations to solve simultaneously
From i, x = 3.5 - y
insert into ii
53(3.5-y) + 58y = 195.5
185.5 - 53y + 58y = 195.5
5y = 195.5-185.5
5y = 10
y = 10/5
y = 2 hours
x = 3.5 - y
x = 3.5 - 2
x = 1.5 hours

Read this excerpt from A Black Hole is NOT a Hole.
Luckily, you can visit a black hole with your imagination. Fueled by facts, you can blast off to a black hole or two and find out what might happen once you arrive.
What does the author mean?
Imagination is not helpful when studying for a science test.
Facts decrease creativity when a reader cannot experience something firsthand.
Facts allow a reader to envision what they cannot experience firsthand.
Imagination is useful when writing a research paper.

Seven out of ten people say they will vote for Mrs. Meekus . If 5,500 people vote,how many are likely to vote for Mrs.Meekus
Answer:
3,850 people are likely to vote for Mrs. Meekus.
Step-by-step explanation:
Given that Mrs. Meekus has a voting intention of 7 out of 10, that is, 70%, in the event that 5,500 people are going to vote in the elections, the voting intention for this candidate would be obtained through the following calculation:
5,500 x 0.70 = X
3,850 = X
Thus, if said voting intention is reproduced, Mrs. Meekus would be voted by 3,850 voters.
Which of the following terms best describes three points that all lie in a
straight line?
A. Collinear
B. Congruent
C. Midpoint
D.equal
Answer:
A.
Explanation:
Collinear
The required term is "collinear" which best describes three points that all lie in a straight line. which is the correct answer would be an option (A).
What are the collinear points?Collinear points are locations along a straight line that are represented by a collinear. They are always collinear since a straight line may be traced continuously between any two places. A collinear connection can exist between three or more points, but it is not required. The word required is "collinear," which best depicts three locations that are all in a straight line.
Therefore, the required term is "collinear" which best describes three points that all lie in a straight line.
Hence, the correct answer would be option (A).

20. John Navarro is a salesperson in the appliance department at Morris
Appliance, Inc. He is guaranteed a minimum salary of $185 per week, or
5.5 percent of his total sales—whichever is greater. What is his gross pay
for a week in which his total sales were $3,422?
Answer:
$373.21Step-by-step explanation:
Step one:
weekly pay = $185
commission= 5.5% of sales= 0.055
let the sale be x
and his gross pay be represented by y
hence the expression for the total/gross pay is
y=0.055x+185
Step two:
Required is the gross pay y for x=3422
substituting we have
y=0.055*3422+185
y=188.21+185
y=373.21
Hence for a sale of $3,422 made his gross pay is $373.21
Write and solve an equation to find the value of x. PLS HELP!!
Answer:
23.59 - 14.89 = x
x = 8.7
Step-by-step explanation:
To find x, you need to add all of the other sides and subtract it from the perimeter. 5.62 + 5.62 + 3.65 = 14.89.
23.59 - 14.89 = x, so x = 8.7
Answer:
8.7
Step-by-step explanation:
Add all the numbers together (5.62, 5.62, and 3.65) then take away from the result (23.59) to get answer.
