Find the indicated z score. The graph depicts the standard normal distribution with
mean 0 and standard deviation 1.
The indicated z score is
(Round to two decimal places as needed.)
Z 0
0.8289
Using the normal distribution, it is found that the indicated z-score is Z = 1.08. A normal distribution with a mean of zero and a standard deviation of one is known as the standard normal distribution.
What is meant by standard normal distribution?A normal distribution with a mean of zero and a standard deviation of one is known as the standard normal distribution. The standard normal distribution is centered at zero, and the standard deviation indicates how much a specific measurement deviates from the mean.
While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.
The z-score of a measure X in a normal distribution with mean and standard deviation is given by:
z = (x-μ)/σ,
It counts the number of standard deviations the value deviates from the mean.
We look at the z-score table after determining the z-score to determine the p-value, which is the percentile of X.
We want Z in this problem to have a p-value of 0.8599, thus Z = 1.08.
The complete question is,

Write the following comparison as a ratio reduced to lowest terms.
114 hours to 13 days
The ratio of 114 hours to 13 days is 19:52.
How to calculate the ratio?It should be noted that ratio is simply used to show the comparison between two things that are illustrated.
In this case, we want to calculate the ratio of 114 hours to 13 days. It should be noted that 24 hours make one day. Therefore, 13 days will be:
= 13 × 24 = 312 hours.
The ratio of 114 hours to 13 days will be:

Applying the relations given, considering equivalent angles, the trigonometric measures for the angles are given as follows:
sin(240º) = -sqrt(3)/2.cos(225º) = -sqrt(2)/2.tan(225º) = 1.How to find the sine of 240º?The sine of 240º can be written as follows:
sin(240º) = sin(180º + 60º).
Applying the first relation given on the second line, we have that:
sin(180º + 60º) = -sin(60º)
It is known that sin(60º) = sqrt(3)/2, hence the sine of 240º is given as follows:
sin(240º) = -sin(60º) = -sqrt(3)/2.
How to find the cosine of 225º?The cosine of 225º can be written as follows:
cos(225º) = cos(180º + 45º).
Applying the second relation given on the second line, we have that:
cos(180º + 45º) = -cos(45º)
It is known that cos(45º) = sqrt(2)/2, hence:
cos(225º) = -cos(45º) = -sqrt(2)/2.
How to find the tangent of 225º?The tangent of 225º can be written as follows:
tan(225º) = tan (180º + 45º).
Applying the third relation given on the second line, we have that:
tan(180º + 45º) = tan(45º)
It is known that tan(45º) = 1, hence:
tan(225º) = tan(45º) = 1.

please help 4. What is the loan payment on a fixed-rate/fixed-term mortgage loan of $100,000 at 8% for 30 years? (LO 7-3).
the loan payment on a fixed term mortgage loan of $100,000 at 8% for 30 years will be $ 340,000.
Principal amount = $ 100,000
Interest rate = 8 %
Time period = 30 years.
Now, the interest is simple interest as it is a fixed rate/ fixed term mortgage.
So, the interest will be:
Simple interest = p r t / 100
SI = 100,000 × 8 × 30 / 100
SI = $ 240,000
Amount will be:
A = $100,000 + $ 240,000
A = $ 340,000

Grant orders a $55 bouquet of flowers to be delivered to his sister. He pays the bill plus a 6.5% sales tax and a 15% tip on the total cost including tax. He also pays a $10 delivery fee that is charged after the tax and tip. How much change does he receive to the nearest cent, if he pays the delivery driver with a $100 bill?
The change that Grant received to the nearest cent after giving the delivery driver with a $100 bill is $ 32.6.
This is a question of percentages.
Given that:-
Price of bouquet of flowers = $ 55
Sales tax % = 6.5 %
Tip % = 15 %
Delivery fee= $10
We have to find the change that Grant received to the nearest cent after giving the delivery driver with a $100 bill.
Sales tax = (6.5/100)*55 = $3.575
$55 + $3.575 = $58.575
Tip = (15/100)*58.575 = $ 8.78625
Total money paid by Grant = 55 + 3.575 + 8.78625 = $ 67.36125 ≈ $ 67.4

Book valueGiven data:
Cost = $26,000
Useful life = 5 years
Salvage value = $3,200
First step is to calculate the depreciation expenses:
Particular Amount
Cost $26,000
Less: Salvage value ($3,200)
Net cost (a) $22,800
Useful life (b) 5
Depreciation expenses (a/b) $4,560

Total number of jerseys he have now is 32 jerseys.
A coach has 12 jerseys in beginning. Now, he buys 2 sets of jerseys.
Each set of jerseys have 10 jerseys.
2 set of jerseys have 20 jerseys.
Using unitary method this can also be written as,
1 set ----------------> 10 jerseys
2set ----------------> 20 jerseys
So, total of 20 jerseys are present in 2 sets of jerseys.
Total number of jerseys he have now = 12 jerseys + jerseys in two sets
Total number of jerseys he have now = 12 jerseys + 20 jerseys = 32 jerseys
So we can write, he have total of 32 jerseys now.

This is called conditional probability and is given by
[tex]P(A|B)=\frac{P(A\: and\: B)}{P(B)}[/tex]This means that the probability of event A given that event B has occurred.
For the given case, it becomes
[tex]P(Cookies|Coffee)=\frac{P(Cookies\: \: and\: \: Coffee)}{P(Coffee)}[/tex]The probability P(Cookies and Coffee) is the intersection of the column "Cookies" and the row "Coffee" divided by the grand total.
[tex]P(Cookies\: \: and\: \: Coffee)=\frac{5}{33}[/tex]The probability P(Coffee) is the row total of the row "Coffee" divided by the grand total.
[tex]P(Coffee)=\frac{20}{33}[/tex]Finally, the conditional probability is
[tex]P(Cookies|Coffee)=\frac{P(Cookies\: \: and\: \: Coffee)}{P(Coffee)}=\frac{\frac{5}{33}}{\frac{20}{33}}=\frac{5}{33}\cdot\frac{33}{20}=\frac{5}{20}=\frac{1}{4}=0.25[/tex]Therefore, the probability that it contains cookies given that it contains coffee is 0.25
2. Find two ordered pairs that make the equation – 2x + y = 8 true. Show all work.
Answer:
(0, 8) and (-4, 0)
Step-by-step explanation:
Equation is -2x + y = 8
Manipulate this equation so that it becomes a slope-intercept form of equation
To do this:
Add 2x on both sides
-2x + 2x + y = 2x + 8
y = 2x + 8
Once we have this, 2 points which definitely lie on the line are its x and y intercepts
This is the equation of a line with slope = 2 and x-intercept = 8
x-intercept is y-value when x = 0
We can check by plugging in 0 for x in y = 2x + 8
=> y = 2(0) + 8 = 8
=> Point(0, 8) is one of the ordered pairs
Similarly we can find the x-intercept by setting y = 0 and solving for x
Setting y = 0 in y = 2x + 8
=> 0 = 2x + 8
Switch sides
2x + 8 = 0
Subtract 8 from both sides
2x + 8 - 8 = 0 - 8
2x = -8
Divide both sides by 2
=> 2x/2 = -8/2
x = -4
So (-4, 0) is another point on the line
Two ordered pairs are therefore
(0, 8) and (-4, 0)
The attached graph shows you that it is indeed so
