Click the icon to view a table of English and Metric Equivalents.
Answer: Kukui (Hawaii) has the greater average rainfall than Melchior (Antarctic Peninsula) by 8,099.2 millimetres.
Step-by-step explanation:
Given: The average rainfall amounts for two of the world's wettest places:
Kukui (Hawaii): 9,293 millimetres
Melchior (Antarctic Peninsula): 47 inches
Since 1 inch = 25.4 millimetres
∴ 47 inches = 47 × 25.4 millimetres
= 1193.8 millimetres
i.e. Melchior (Antarctic Peninsula) has 1193.8 millimetres of average rainfall.
Clearly, 9,293 millimetres> 1193.8 millimetres
So, Kukui (Hawaii) has the greater average rainfall .
Difference = 9293 - 1193.8 = 8099.2 millimetres
So Kukui (Hawaii) has the greater average rainfall than Melchior (Antarctic Peninsula) by 8,099.2 millimetres.

A church group interested in promoting volunteerism in a community chooses an SRS of 200 community addresses and
sends members to visit
these addresses during weekday working hours to inquire about the residents attitudes toward volunteer work. Sixty percent of all
respondents say that they would be willing
to donate at least an hour a week to some volunteer organization. Bias is present in this sample
design. Identify the type of bias involved and state whether you think the
sample percent obtained is higher or lower than the true population
percent.
Answer:
if the polling were done during working hours, those who work outside the home would not be included-undercoverage of the groupe. the 60% is probably higher than the true population proportion. face-to-face visits might make those at home likely to say they would volunteer.

NEED ANSWER NOW!!! Steven has one bag that contains three table tennis balls numbered 1, 2, and 3. He also has a second bag that contains four table tennis balls lettered A, B, C, and D. Suppose Steven combined the table tennis balls into one large bag instead of two individual bags. What would be the P(1, B) without replacement?
Answer:
P(1, B) = 1/12
Step-by-step explanation:
if given one group of 3 objects, in this case tennis balls labeled 1, 2, and 3. And another group of 4 objects, labeled a, b, c, and d. the combined probability would be 1/3 * 1/4 = 1/12. This is because there is a 1/3 chance of picking one particular object from a set of 3 total objects, and a 1/4 chance of picking one particular object from a set of 4 total objects.
The probability of drawing 1 numbered ball in the first attempt and then drawing B numbered ball in the second attempt is 1/42.
What is conditional probability ?Conditional probability is when occurrence of an event depends upon the occurrence of another event.In case of without replacement one event is dependent on another.
According to the given question
Steven has one bag that contains three table tennis balls numbered 1, 2, and 3. He also has a second bag that contains four table tennis balls lettered A, B, C, and D and Steven combined the table tennis balls into one large bag instead of two individual bags.
Here we don't need to find the probabilities individual bags.
So after he combined them into one large bag there are 7 balls in that large bag namely 1, 2, 3, A, B, C, D
P(1) = 1/7
with without replacement there is now 6 balls in the large bag
∴ p(B) = 1/6
So the probability of drawing 1 numbered ball in the first attempt and then B numbered ball in the second attempt is p(1)p(B)
∴P(1,B) is
= (1/7)×(1/6)
= 1/42.

A normal distribution has a mean of 186.4 and a standard deviation of 48.9. What percent of data will be greater than 235.3?
Answer:
15.9% of the data will be greater than 235.3.
Step-by-step explanation:
Use a calculator with statistical functions. In this case you'll need the cumulative normal distribution: normcdf(.
Evaluate the following: normcdf(235.3, 10000,186.4, 48.9):
We get: 0.159, or 15.9%
15.9% of the data will be greater than 235.3.
The range of value X > 284.2 of data will be greater than 235.3.
What is a z-score?A Z-Score is a statistical measurement of a score's relationship to the mean in a group of scores.
We know that the upper 2.5% of data would be 97.5% of data.
We will use a z-score formula to solve our given problem.
[tex]\rm z=\dfrac{x-\mu}{\sigma}[/tex]
Where; z = z-score,
x = Random sample score,
[tex]\mu[/tex] = Mean,
[tex]\sigma[/tex] = Standard deviation.
We will use a normal distribution table to find a z-score corresponding to 97.5% area or 0.975.
We can see from the normal distribution table that the z-score corresponding to the area of 0.975 is 1.96.
[tex]\rm 1.96=\dfrac{x-186.4}{48.9}\\\\1.96 \times 48.9 =x-186.4\\\\x = 186.4 +95.84\\\\x=282.84[/tex]
Hence, the range of value X > 284.2 of data will be greater than 235.3.

100 POINTSSSS!! I AM IN DESPERATE NEED OF HELP! so like help? i am struggling with the part where i make an equation for the blocks. i have a few more problems like this to do, so please give me a full explanation of how you solved it. thank you!!
Numbers 1 and 2 are correct.
Question 3:
We can see in each figure, the number of rows matches the figure amount. For example, figure 1 has 1 row, figure 2 has 2 rows, figure 3 has 3 rows, etc. Another thing we can see is that one block gets added to each column in every figure. If we count starting from 3 and keep adding 1 for each column, we get 22 blocks for one column. In figure 20, there will be 20 rows and 22 columns. We also have to keep in mind that they add 2 extra blocks at the top and bottom that stick out like the ones shown. In total, figure 20 will consist of 442 blocks.
Question 4:
[(2 + f) * (f)] + 2 = b
(2 + f) represents the number of blocks in each column.
(f) represents the number of blocks in each row.
2 represents the two extra blocks in each figure.
Note that f in this equation equals the number of the figure. For example, figure 3 is f = 3
We can test our equation with figure three.
[(2 + f) * (f)] + 2 = b
We have figure three so f = 3. Substitute and solve.
[(2 + 3) * (3)] + 2 = b
[5 * 3] + 2 = b
15 + 2 = b
17 = b
In the example, the number of blocks is 17. Therefore, this equation works for any figure.
Best of Luck!
Answer:
We will see that the number of rows in each figure corresponds to the figure amount. Figure 1 has one row, figure 2 has two rows, figure 3 has three rows, and so on. Another thing we can see is that in each diagram, one block is attached to each column. We get 22 blocks for one column if we count from 3 and keep adding 1 for each column. There will be 20 rows and 22 columns in Figure 20. We must also remember that they add two additional blocks at the top and bottom that protrude like the ones shown. Figure 20 will have a limit of 442 blocks.
4th question:
[(2 + f) * (f)] [(2 + f) * (f)] [(2 + f) 2 + 1 = b
The number of blocks in each column is represented by (2 + f).
The number of blocks in each row is represented by (f).

solve for x 5x-2=3x+4
Answer:
3
Step-by-step explanation:
Simplifying
5x + -2 = 3x + 4
Reorder the terms:
-2 + 5x = 3x + 4
Reorder the terms:
-2 + 5x = 4 + 3x
Solving
-2 + 5x = 4 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-2 + 5x + -3x = 4 + 3x + -3x
Combine like terms: 5x + -3x = 2x
-2 + 2x = 4 + 3x + -3x
Combine like terms: 3x + -3x = 0
-2 + 2x = 4 + 0
-2 + 2x = 4
Add '2' to each side of the equation.
-2 + 2 + 2x = 4 + 2
Combine like terms: -2 + 2 = 0
0 + 2x = 4 + 2
2x = 4 + 2
Combine like terms: 4 + 2 = 6
2x = 6
Divide each side by '2'.
x = 3
Simplifying
x = 3

If m rst= 12x-1, m rsu = 9x-15 and m ust = 53 find each measure
Answer:
x = 13
m<RST = 155°
m<RSU = 102°
Step-by-step explanation:
m<RST = (12x - 1)°
m<RSU = (9x - 15)°
m<UST = 53°
m<UST + m<RSU = m<RST (angle addition postulate)
53 + (9x - 15) = (12x - 1) (substitution)
Solve for x
53 + 9x - 15 = 12x - 1
53 - 15 + 9x = 12x - 1
38 + 9x = 12x - 1
Subtract 12x from each side
38 + 9x - 12x = 12x - 1 - 12x
38 - 3x = - 1
Subtract 38 from each side
38 - 3x - 38 = -1 - 38
-3x = -39
Divide both sides by -3
x = 13
m<RST = (12x - 1)°
Plug in the value of x
m<RST = 12(13) - 1 = 156 - 1 = 155°
m<RSU = (9x - 15)°
m<RSU = 9(13)x - 15 = 117 - 15 = 102°
The measures of each angle are:
m<RSU = 102°
m<RST = 155°
m<UST = 53°
The given parameters are:
m<RST = (12x - 1)°
m<RSU = (9x - 15)°
m<UST = 53°
Note that:
m<RST = m<RSU + m<UST
Substitute m<RST = 12x - 1, m<RSU = 9x - 15, and m<UST = 53 into the equation above in order to solve for x
m<RST = m<RSU + m<UST
12x - 1 = 9x - 15 + 53
12x - 9x = -15 + 53 + 1
3x = 39
x = 39/3
x = 13
To find the measure of <RST, substitute x = 3 into m<RST = 12x - 1
m<RST = 12(13) - 1
m<RST = 155°
To find the measure of <RSU, substitute x = 3 into m<RSU = 9x - 15
m<RSU = 9(13) - 15
m<RSU = 102°
