For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98
What is empirical rule?Empirical rule states that for a normal distribution, 68% of the values are within one standard deviation from the mean, 95% of the values are within two standard deviation from the mean and 99.7% of the values are within three standard deviation from the mean.
For a population mean of 20.15 and a standard deviation of 3.7:
68% are within μ ± σ/√n, hence:
68% = 20.15 ± 3.7/√20 = (19.32, 20.98)
For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98

First you find the volume of one cube by doing 1/2*1/2*1/2, after this you times this number by 16 to get the volume of the whole structure
The volume of the jar is 88, it has a radius sq. of 4. What is the height of the jar? Round the answer to the nearest unit.
Answer:
The height of the jar is 1.75.
Step-by-step explanation:
Given that the volume of the jar is 88, and it has a radius of 4, to determine what is the height of the jar, the following calculations must be performed, knowing that the volume of a cylinder arises from multiplying pi by the radius squared, and multiplying that result by the height:
3.14 x 4 ^ 2 x H = 88
3.14 x 16 x H = 88
50.24 x H = 88
H = 88 / 50.24
H = 1.75
Thus, the height of the jar is 1.75.

C. Negatively skewed, and the mean is to the right of the median.
D. Positively skewed, and the mean is to the left of the median.
Please help branliest to correct answer
The given histogram is Negatively skewed, and the mean is to the right of the median.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
For a symmetric histogram, the values of the mean, median, and mode are all the same and are all located at the center of the distribution.
A negatively skewed distribution is a type of distribution in which more values are concentrated on the right side of the distribution graph while the left tail of the distribution graph is longer
The data distributed where is the mean located in relation to the median is to the right side.
Hence, the given histogram is Negatively skewed, and the mean is to the right of the median.

The price for a car in 2015 was RM 54000. This was 10% higher compared to the year 2014?
Answer:
2014 price was $49,091
Step-by-step explanation:
I'm assuming you want to solve for 2014 year price...
2015 year price is 54,000 and was 10% higher than 2014 price, meaning 2015 price is 110% of 2014 price so...
p×110%=54,000
p=54,000/1.1
p=49,090.90
what is value of x in 96-3x=6
Answer:
X= 30
Step-by-step explanation:
96-3x=6
first move all terms not containg x to the right side of the Equation
Subtract 96 from both sides of the equation.
-3x = 6 - 96
subtract 96 from 6 and u will get
-3x= -90
Then u will have to divide each term by -3 and simplify which will get u
-3x/-3 when u divide from that u should get -90/-3
Then divide x by 1 and itll equal
x= -90/-3
Then divide -90 by -3 and you will get
x= 30

Ms. Watson's recipe uses
1 cup of milk to make 12 biscuits.
How many cups of milk will be used to make 36 biscuits?
Answer:
1 cup = 12 biscuits
2 cups = 24 biscuits
3 cups = 36 biscuits
So, 3 cups make 36 biscuits.
Step-by-step explanation:
36 ÷ 12 = 3
Answer:
3 cups of milk
Step-by-step explanation:
1 cup = 12 biscuits
x cups = 36 biscuits
1/12 = x/36
cross multiply
36 = 12x
36/12 = 12x/12
3 = x
3. Find the equation of a line that passes through the x-intercept of the line 3x+ 6y = 8 and is perpendicular to the line 2x - 5y = 10.
Answer:
y = -5/2x + 20/3
Step-by-step explanation:
x-int of 3x + 6y = 8
sub 0 for y
3x + 6(0) = 8
3x = 8
x = 8/3 or 2.667
line perpendicular to 2x - 5y = 10
put into y = mx + b form
2x - 5y - 10 = 0
5y = 2x - 10
y = 2/5 x - 2
find negative reciprocal of the slope 2/5 x (for the perpendicular line)
-5/2 x
find the y-int (b)
m = -5/2 x
must pass through (8/3,0)
y = mx + b
0 = -5/2(8/3) + b
0 = -40/6 + b
b = 20/3
therefor the equation of the line is y = -5/2x + 20/3

The Sweetings are building an ornamental garden pond. They intend to lay 1m square slabs around its perimeter. If the pond is 8m by 8m, how many slabs will they need?
Answer:
32 slabs are needed
Step-by-step explanation:
If the pond is 8m by 8m, then that means each side is equal, and each side is 8m long. There are 4 sides to the perimeter of the pond. To find how many slabs you need, you need to found out how many meters long the perimeter of the pond is in total. To do so, you must multiply the length of one side of the perimeter to the number of sides there is. The length of one side of the perimeter is 8m, and the number of sides is 4, which means you must multiply 8 by 4, which equals 32.
