Find the value of z such that 0.02 of the area lies to the right of z. Round your answer to two decimal places.
The value of z-score such that 0.02 of the area lies to the right of z would be 2.06.
Given that,
0.02 of the area lies to the right of z.
Now, for the value of z such that 0.02 lies to the right of z, we can make use of the standard normal distribution table.
Since to determine the value of z such that 0.02 of the area lies to the right, we need to find the z-score associated with the cumulative probability of (1 - 0.02) = 0.98
Now for the value of 0.98 in the standard normal distribution table, we find that the corresponding z-score is 2.06.
Therefore, the value of z, rounded to two decimal places, is 2.06.

The value of z such that 0.02 of the area lies to the right of z is approximately 2.05 (rounded to two decimal places).
To find the value of z such that 0.02 of the area lies to the right of z, we need to determine the z-score associated with that probability.
Since we're looking for the area to the right of z, we can use the standard normal distribution table or a statistical calculator to find the corresponding z-score.
By searching the table or using a calculator, we can find that the z-score associated with a right-tail probability of 0.02 is approximately 2.05.

A parallelogram has a base of 9 units and a corresponding height of į units. What is its area?
Do not include units (square units) in your answer.
Answer:
[tex]Area = 9j[/tex]
Step-by-step explanation:
Given
[tex]Base = 9\ units[/tex]
[tex]Height = j\ units[/tex]
Required
Determine the area
Area of parallelogram is calculated as thus:
[tex]Area = base * Height[/tex]
Substitute values for Base and Height
[tex]Area = 9 * j[/tex]
[tex]Area = 9j[/tex]
Hence, the area of the parallelogram whose base is 9 units and height is j units, is 9j

Find the distance between (6,4) and (-6,-5) by using the distance formula
Answer:
[tex]\boxed {d = 15}[/tex]
Step-by-step explanation:
Use the Distance Formula to help determine the distance between two given points:
[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]
First point: [tex](x_{1}, y_{1})[/tex]
Second point: [tex](x_{2}, y_{2})[/tex]
-Substitute both given points:
[tex](x_{1}, y_{1}) = (6, 4)[/tex]
[tex](x_{2}, y_{2}) = (-6, -5)[/tex]
[tex]d = \sqrt{(-6 - 6)^{2} + (-5 - 4)^{2}}[/tex]
-Solve for the distance:
[tex]d = \sqrt{(-6 - 6)^{2} + (-5 - 4)^{2}}[/tex]
[tex]d = \sqrt{(-12)^{2} + (-9)^{2}}[/tex]
[tex]d = \sqrt{144 + 81}[/tex]
[tex]d = \sqrt{225}[/tex]
[tex]\boxed {d = 15}[/tex]
Therefore, the distance is [tex]15[/tex].
A swimming pool has two pipes coming into it to fill it with water. One pipe takes 16 hours to fill it. The other takes 12 hours to fill it. How many hours will it take both pipes to fill the pool?
Answer:
8 hours
Step-by-step explanation:
8 hours because half of 16 is 8 and half of 12 is 6
If it takes 6 hours to fill one half then the other 2 hours would go to the other pipe making it 8 hours
A newspaper ran a story concerning the increasing prices of mobile phones. The story stated that mobile phone prices dropped a few years ago, but now are beginning to increase in price because of added features.
• According to the story, the average price of all mobile phones a few years ago was £215.
• A large random sample of mobile phones (n = 200) was taken, and their prices recorded.
• We wish to use a hypothesis test to determine if the average price of all mobile phones is now greater than £215.
Required: Define the hypotheses, and with reference to the applicable random variable distribution, find the rejection region appropriate for this test if we are using the significance level α = 0.05.
Answer:
H0 : μ = 215
H1 : μ > 215
Rejection region :
Zstatistic > Z0.05
Step-by-step explanation:
Given that:
Average price of all mobile phones was £215
Sample size = 200
Significance level (α) = 0.05
To determine if the average price of all mobile phones is now greater than £215
The Null hypothesis (H0) :
H0 : μ = 215
Alternative hypothesis (H1) :
H1 : μ > 215
The rejection region :
|Zstatistic > Zα|
α = 0.05 ; Z0.05
Rejection region :
Zstatistic > Z0.05

Assuming you meant to put 20 - (1.27)x, it is decay. As the x increases, the y decreases, making it decay.
Consider the equation 5x + 7 = 2x + 28. Your tasks to explain the steps you would take, in
order, to solve the equation for x. Imagine that you are writing this for someone who is learning
about this process for the first time. You would be as specific as possible and write in complete
sentences.
Answer:
x=7
Step-by-step explanation:
Step 1: Put the variables and constants on the same side and change their signs so it'll look like this 5x-2x = 28 - 7, you always move the smaller number to either the left or right depending on its position in the problem.
Step 2: solve each side normally like this, 3x = 21
Step 3: to get x by itself divide 3 on both sides and you should get x=7
Here's a run through of the steps
5x+7=2x+28
-7 -7(subtract 7 from both sides
5x=2x+28-7
-2x -2x(subtract 2x from both sides)
5x-2x=28-7
3x=21
3x/3 = 21/3 (divide 3 from both sides)
x=7

zach says that the expressions 6x - 36 and 3(2x -12) are equivalent
Answer:
True
Step-by-step explanation:
When you distribute the 3, you get x(2x3)-(12x3)
2x3=6
12x3=36
so 6x-36
and that is equivalent to the first expression.
Jose gets his hair cut for $12. He gives his barber a
15% tip. How much does he give the barber for a tip?
(If you have big brain plz help me)
Answer: $3
Step-by-step explanation:
If you want to tip 15%, then the total tip amount would be $2.40 plus half of that again ($1.20), which is $3.60.
Jose gives the barber a $1.80 tip.
What is a percentage?A percentage is a ratio or number that may be expressed as a fraction of 100. Moreover, it is denoted by the sign "%."
Given information:
Jose gets his hair cut for $12.
He gives his barber a 15% tip.
To calculate the tip, we need to find 15% of the cost of the haircut.
15% can be written as a decimal as 0.15.
So, the tip amount is:
0.15 x $12 = $1.80
Therefore, Jose gives the barber a $1.80 tip.
