Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a standard deviation of 1300 hours and a mean life span of 15,000 hours. If a monitor is selected at random, find the probability that the life span of the monitor will be more than 17,340 hours.
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

According to the National Center for Health Statistics, in 1990, 28% of babies in the United States were born to parents who were not married. Throughout the 1990s, this increased by approximately 0.6% per year. If this trend continues, in which year will 31% of babies be born out of wedlock?
Answer:
The year is [tex]b = 1995[/tex]
Step-by-step explanation:
From the question we are told that
The percentage of the number of babies born out of wedlock in 1990 is k = 28%
The percentage by which the number increase per year is i = 0.6%
The percentage of of the number of babies born out of wedlock considered is a = 31%
Generally the difference in between the percentage in 1990 and the percentage considered is
[tex]d = a - k[/tex]
=> [tex]d = 31 - 28[/tex]
=> [tex]d = 3\%[/tex]
Generally the number of year require for the percentage to be equal to 31% is mathematically represented as
[tex]n = \frac{3\%}{0.6\%}[/tex]
=> [tex]n = 5\ years[/tex]
Generally the year which the considered percentage will be attained is
[tex]b = 1990 + n[/tex]
=> [tex]b = 1990 + 5[/tex]
=> [tex]b = 1995[/tex]

In a really exciting part of the book, the student read 18 pages in
one sitting. For how many minutes did she read?
Answer:
the student read for 36 minutes
Step-by-step explanation:
so for each night minutes read is going to represent the minutes read and y is going to represent the pages read. This means that 18 should be substituted in for y.
18=1/2x
so to solve you are going to divide both sides by 1/2
36=x

Answer: 4 1/2
Step-by-step explanation:
The absolute value of a given number is [tex]4\frac{1}{2}[/tex].
What is an absolute value?The absolute value of a number is defined as its magnitude irrespective of the sign of the number. To find the absolute value of a real number, we consider only the number and remove the sign. It can only be a non-negative value.
The given number is [tex]-4\frac{1}{2}[/tex].
So, absolute value of a number is
|[tex]-4\frac{1}{2}[/tex]|= [tex]4\frac{1}{2}[/tex]
Hence, the absolute value of a given number is [tex]4\frac{1}{2}[/tex].

A slow pitch softball diamond is actually a square 61 ft on a side. How far is it from home to second base?
Answer:
This would be the same as an isosceles right triangle. It would be 61ft x (square root of 2) = ~86.3ft
This is rounded of course...
The distance from from home to second base is 86.26 ft.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Given that, a slow pitch softball diamond is actually a square 61 ft on a side.
A slow-pitch softball diamond is actually a square shape.
The side length of the square is 61 ft
Here ABCD is square. The length of the side is AB=BC=CD=DA=60 feet.
Consider the distance between home base to second base is the hypotenuse if we draw a right triangle using the diagonal across the square and two sides of the square.
Let us assume the diagonal distance from home to second base BD=x.
Let us find the distance from home base to second base by using Pythagorean Theorem:
Now, x²=61²+61²
x²=3721+3721
x²=7442
x=√7442
x=86.26 ft
Therefore, the distance from from home to second base is 86.26 ft.

What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
Point B(-4, - 6) is given lies on the third quadrant.

But if we reflect point B(-4, - 6) along the origin it would be B'(4, 6).

Find the difference between 3 1/12 and 2 1/6. Leave your answer as a proper fraction or mixed number.
Answer:
[tex]\frac{8}{6}=1\frac{1}{3}[/tex]
Step-by-step explanation:
[tex]3\frac{1}{2}-2\frac{1}{6}[/tex] Fractions cannot be added or subtracted unless they have the same denominator (bottom number)
[tex]\frac{7}{2}-\frac{13}{6}[/tex] Change to an improper fraction. Multiply the denominator times the whole number (number on the side) then add to the numerator (top number) and place over the the denominator (3*2+1=7→[tex]\frac{7}{2}[/tex])
[tex](\frac{7}{2}*\frac{3}{3})[/tex] - [tex]\frac{13}{6}[/tex] In order to give both fractions the same denominator, find the least common denominator (LCD = one number that both denominators will divide evenly into) LCD = 6. Then multiply the top and bottom by a number that gives the LCD. We only need to multiply the first fraction top and bottom by 3.
[tex]\frac{21}{6} - \frac{13}{6} = \frac{8}{6}[/tex] This is an improper fraction because the numerator is larger than the denominator. To make a mixed number divide the numerator by the denominator and simplify.
[tex]\frac{8}{6} = 1\frac{2}{6} = 1\frac{1}{3}[/tex] [tex](\frac{2}{6} \frac{divided by}{divided by}\frac{2}{2} = \frac{1}{3})[/tex]

A marketing consultant is hired by a major restaurant chain wishing to investigate the preferences and spending patterns of lunch customers. The CEO of the chain hypothesized that the average customer spends at least $13.50 on lunch. A survey of 25 customers sampled at one of the restaurants found the average lunch bill per customer to be x¯= $14.50. Based on previous surveys, the restaurant informs the marketing manager that the standard deviation is ???? = $3.50. To address the CEO’s conjecture, the marketing manager decides to carry out a test of hypothesis. The null hypothesis is given by H0 : ???? = 13.50. The hypothesis test is set up to provide the marketing manager with:
a. proof that the null hypothesis is true.
b. evidence against the null hypothesis in favor of the alternative.
c. evidence against the alternative hypothesis in favor of the null hypothesis.
d. evidence in favor of the null hypothesis.
Answer:
t = 1.399<1.710 ( from tabulated value)
we will accepted the null hypothesis
the marketing manager decides to carry out a test of hypothesis
H 0 : μ = 13.50
Step-by-step explanation:
Step1 :-
Given sample size 'n' = 25 customers
The CEO of the chain hypothesized that the average customer spends at least $13.50 on lunch.
therefore the population mean 'μ' = $13.50
A survey of 25 customers sampled at one of the restaurants found the average lunch bill per customer to be ¯ x = $ 14.50
sample mean ¯ x = $ 14.50
the restaurant informs the marketing manager that the standard deviation is σ = $ 3.50
Population standard deviation σ = $ 3.50
Step 2:-
we will use' t' test because of given small sample size is n=25
Null hypothesis: H₀ : μ= $ 13.50
Alternative hypothesis :H₁:μ ≠ $ 13.50
Degrees of freedom γ = n-1 = 25-1 =24
The test statistic 't' is
substitute all values , we get
t = 1.399
This is calculated value t = 1.399
The tabulated value of t are 5% level with 24 degrees of freedom
t = 1.710
Step 3:-
t = 1.399<1.710
Since calculated value < The tabulated value of t are 5% level with 24 degrees of freedom.
we will accepted the null hypothesis
the marketing manager decides to carry out a test of hypothesis
Write an

Answer:
Slope=2.
Step-by-step explanation:
Slope=y1-y2/x1-x2
Where
X1,y1,=(-5, -11) X2,y2=(6,11).
Slope=-11-11/-5-6
=-22/-11
=22/11
=2
Slope is 2
Answer:
2
Step-by-step explanation:
Here,
x₁ = (- 5) and x₂ = 6
y₁ = (- 11) and y₂ = 11
Now,
Slope
= y₁ - y₂ ÷ x₁ - x₂
= (- 11) - ( 11) ÷ (- 5) - ( 6 )
= - 11 - 11 ÷ - 5 - 6
= - 22 ÷ - 11
= 2 ÷ 1 = 2
Thus, Slope is 2
