mu = 1100 = population mean
sigma = 275 = population standard deviation
x = 1400 = raw score
z = z score
z = (x-mu)/sigma
z = (1400-1100)/(275)
z = 300/275
z = 1.0909090909091 approximately
z = 1.09
Convention is to round to two decimal places so that you can use a Z table to look up the area under the curve (which helps determine probability).
The positive z score is due to Paula's raw score being above the mean.

You have put ₹ 2500 in your bank account. After some years, you observe that you have received interest and the amount now is ₹ 4100. What is the percentage of increase?
Answer:
64%
Step-by-step explanation:
The first step is to calculate the increase
= 4100-2500
= 1600
Therefore the percentage increase can be calculated as follows
= increase/original number × 100
= 1600/2500 × 100
= 0.64 × 100
= 64%
Hence the percentage increase is 64%

6. When rounded to the nearest hundredth, log, 7 =1.77. Which of the following represents the value of
log, 63 to the nearest hundredth? Hint: write 63 as a product involving 7.
Note: Consider the base of all is 3 instead of comma.
Given:
Consider the given value is [tex]\log_37=1.77[/tex].
To find:
The value of [tex]\log_363[/tex].
Solution:
Using properties of logarithm, we get
[tex]\log_363=\log_3(9\times 7)[/tex]
[tex]\log_363=\log_3(3^2\times 7)[/tex]
[tex]\log_363=\log_3(3^2)+\log_3(7)[/tex] [tex][\because \log ab=\log a+\log b][/tex]
[tex]\log_363=2+ \log_3(7)[/tex] [tex][\because \log_aa^x=x][/tex]
[tex]\log_363=2+1.77[/tex] [tex][\because \log_37=1.77][/tex]
[tex]\log_363=3.77[/tex]
Therefore, the value of [tex]\log_363[/tex] is 3.77.
Applying logarithm properties, it is found that:
[tex]\log_3{63} = 3.77[/tex]
We want to find [tex]\log_3{63}[/tex], considering that [tex]63 = 7 \times 9 = 7 \times 3^2[/tex], we have that:
[tex]\log_3{63} = \log_3{(7 \times 3^2)}[/tex]
The first property applied is:
[tex]\log{a \times b} = \log{a} + \log{b}[/tex]
Hence:
[tex]\log_3{63} = \log_3{(7 \times 3^2)} = \log_3{7} + \log_3{3^2}[/tex]
The next property is:
[tex]\log_a{a^b} = b[/tex]
Hence:
[tex]\log_3{7} + \log_3{3^2} = 1.77 + 2 = 3.77[/tex]

Elizabeth goes to a restaurant where her bill comes to $18.50. She leaves the server a 22% tip. What is the total cost of going to the restaurant?
Answer:
22.57
Step-by-step explanation:
multiply 18.50 by .22 and add it to 18.50
Answer:
Elizabeth will pay $22.57 in total at the restaurant.
Step-by-step explanation:
First, you need to find the tip, which is 22% of the bill. 22% of 18.5 is 4.07. Then you add that number to the bill and get 22.57.
Your family is having fried rice for dinner. Your mom asks you to divide the 3 bowls of rice so everyone gets an equal amount. How many servings of size 12 can you make out of the 3 bowls of rice?
Answer:
1/4 equal pieces
Step-by-step explanation:
Total number of bowls of rice = 3
We are seeking servings of size 12
Then it means we are dividing 3bowls into 12 equal pieces
= 3/12 bowls
= 1/4 equal pieces
Which means each member of the family is getting 1/4 each of the bowl of rice
Therefore, 1/4 servings of size 12 can you make out of the 3 bowls of rice

Which ordered pairs are NOT a solution of y = 2x + 1? Select all that apply. (3, 7) (3, 7) (0, 1) (0, 1) (-1, 1) (-1, 1) (-3, -5) (-3, -5) (-2, 3)
Answer:
The ordered pairs are;
(-1,1) and (-2,3)
Step-by-step explanation:
Here, we want to select which ordered pair is not a solution to the given equation
The one that will not be a solution will be a point at which if we insert the x-value into the equation, we do not get the y-value at that point
For (3,7
2(3) + 1 = 7
For 0,1
2(0) + 1 = 1
For (-1,1)
= 2(-1) + 1 = -2 + 1 = -1
This is wrong
(-3,-5)
= 2(-3) + 1 = -6 + 1 = -5
(-2,3)
= 2(-2) + 1 = -4 + 1 = -3
This is wrong also

Answer:-1
Step-by-step explanation:
the output of a function is the y value while the input is the x value.
so the question is asking what does the y value( output) have to be for the x value( input) to be zero.
since the graph is provided we can just look to see where the x values becomes zero ( the y axis is when all y values are zero)
we then can identify that the y intercept is -1

The last time Aiden played baseball, he hit the ball 35% of the times he was at bat. Based on this information, how many times will Aiden hit the ball the next time he plays baseball if he is at bat 20 times?
Answer:
the number of times will Aiden hit the ball is 7
Step-by-step explanation:
The computation of the number of times will Aiden hit the ball is shown below:
She hit 35% of the times
i.e.
= Given percentage of number of times
= 35% of 20
= 35 ÷ 100 × 20
= 0.35 × 20
= 7
Hence, the number of times will Aiden hit the ball is 7
We simply applied the above formula so that the correct value could come

Find the distance from point A(−1, 7) to the line y=3x. Round your answer to the nearest tenth.
Answer:
The distance from the point to the line is approximately 3.2 units
Step-by-step explanation:
Distance From a Point to a Line
Is the shortest distance from a given point to any point on an infinite straight line. The shortest distance occurs when the segment from the point and the line are perpendiculars.
If the line is given by the equation ax + by + c = 0, where a, b and c are real constants, the distance from the line to a point (x0,y0) is
[tex]\displaystyle d= \frac{|ax_0+by_0+c|}{\sqrt{a^2+b^2}}[/tex]
The line is given by the equation:
y=3x. We need to transform it into the specified form.
Subtracting 3x:
y - 3x = 0
Comparing with the general form of the line, we have
a=-3, b=1, c=0
The point (xo,yo) is (-1,7), thus:
[tex]\displaystyle d= \frac{|-3\cdot (-1)+1\cdot 7+0|}{\sqrt{(-3)^2+1^2}}[/tex]
[tex]\displaystyle d= \frac{|3+7|}{\sqrt{9+1}}[/tex]
[tex]\displaystyle d= \frac{|10|}{\sqrt{10}}[/tex]
[tex]\displaystyle d= \frac{10}{\sqrt{10}}[/tex]
[tex]d\approx 3.2[/tex]
The distance from the point to the line is approximately 3.2 units

Rachael earned $42 for 3 1/2 hours at her job today. How much does Rachel earn per hour ?
Answer:
$12
Step-by-step explanation:
It is given that,
Rachael earned $42 for [tex]3\dfrac{1}{2}[/tex] hours at her job today. It means,
For 7/2 hours, earning is $42
For 1 hour, we divide $42 by 7/2 as follows :

Tilly and Lilly worked together on a job. Tilly earned twice as much as Lilly, and together they earned $510. How much did each person earn? Use the 5D Process, showing all your work.
Answer:
Lilly earns $170
Tilly earns $340
Step-by-step explanation:
Given that
Tilly earned twice as much as Lilly
If Lilly's earning = x, then Tilly's earning = 2x
Total amount they both earned = $510
x + 2x = $510
3x = $510
3x / 3 = $510 /3
x = $170
Hence,
Lilly earns x = $170
Tilly earns, 2x = 2* 170 = $340

The fraction equivalent of 13/14% is 13/1400.
If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.
Any fraction can be expressed in decimal form by dividing it by its denominator. One or more digits may continue to repeat indefinitely or the result may come to a stop at some point.
So as per the question, the fraction equivalent of the given number will be
13/14% i.e 13/1400.
Now we have a rational number with us, the equivalent fraction can be obtained by multiplying similar numbers in both the numerator and denominator.
so if we multiply by 2 on both sides the fraction we get will be 26/2800.
so if we multiply by 10 on both sides the fraction we get will be 130/14000.
Hence we will get an infinite number of fractions equivalent to 13/14%.
