Which sum is equivalent to 3/5 + 1/6?
A 6/10+2/10
B 12/30+5/30
C 18/30+5/30
D 3/11+4/11
Answer:
C 18/30+5/30
Step-by-step explanation:
Fractions scare me but I try
First we need to find the sum of 3/5 and 1/6
To do that we turn the denominators into common denominators.
[tex] \frac{18}{30} + \frac{5}{30} [/tex]
then we just add
[tex] \frac{18}{30} + \frac{5}{30} = \frac{23}{30} [/tex]
hope this makes sense

The perimeter of the figure is 60
How to determine the perimeter?The side lengths are given as:
11, 22, and 27 meters
The perimeter of the triangle is the sum of its side length.
So, we have:
Perimeter = 11 + 22 + 27
Evaluate the sum
Perimeter = 60
Hence, the perimeter of the figure is 60

In a normal distribution, 68% of the data fall within how many standard
deviations of the mean?
A. Two standard deviations
B. One standard deviation
C. It cannot be determined from the given information.
D. Three standard deviations
In a normal distribution of data, 68% of the data fall within one standard deviations of the mean.
What do you mean by normally distributed data?Normally distributed data is the distribution of probability which is symmetric about the mean.
The mean of the data is the average value of the given data.The standard deviation of the data is the half of the difference of the highest value and mean of the data set.According to the empirical rule, also known as 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95% and 99.7% of the values lies within one, two or three standard deviations of the mean of the distribution.
[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma) = 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma) = 99.7\%[/tex]
Here the mean of distribution of X is [tex]\mu[/tex] and standard deviation from mean of distribution of X is [tex]\sigma[/tex].
Thus, in a normal distribution of data, 68% of the data fall within one standard deviations of the mean.

Suppose that Upper X has a discrete uniform distribution f left-parenthesis x right-parenthesis equals StartLayout left-brace1st Row 1st Column 1 divided by 3, 2nd Column x equals 1,2,3 2nd Row 1st Column 0, 2nd Column otherwise EndLayout A random sample of n equals 33 is selected from this population. Find the probability that the sample mean is greater than 2.1 but less than 2.4. Express the final answer to four decimal places (e.g. 0.9876).
Answer:
the probability that the sample mean is greater than 2.1 but less than 2.4 is 0.2444
Step-by-step explanation:
Given the data in the question;
x f(x) xp(x) x²p(x)
1 1/3 0.33333 0.33333
2 1/3 0.66667 1.33333
3 1/3 1.00000 3.0000
∑ 2.0000 4.6667
∑(xp(x)) = 2
∑(x²p(x)) = 4.6667
Variance σ² = ∑(x²) - ∑(x)² = 4.6667 - (2)² = 4.6667 - 4 = 0.6667
standard deviation σ = √variance = √0.6667 = 0.8165
Now since, n = 33 which is greater than 30, we can use normal approximation
for normal distribution z score ( x-μ)/σ
mean μ = 2
standard deviation = 0.817
sample size n = 33
standard of error σₓ = σ/√n = 0.817/√33 = 0.1422
so probability will be;
p( 2.1 < X < 2.4 ) = p(( 2.1-2)/0.1422) < x"-μ/σₓ < p(( 2.4-2)/0.1422)
= 0.70 < Z < 2.81
= 1 - ( 0.703 < Z < 2.812 )
FROM Z-SC0RE TABLE
= 1 - ( 0.25804 + 0.49752 )
= 1 - 0.75556
p( 2.1 < X < 2.4 ) = 0.2444
Therefore, the probability that the sample mean is greater than 2.1 but less than 2.4 is 0.2444

How many copies of 1 twelfth are equivalent to 3 sixths? Help!
Answer:
6/12 is equal to 3/6 ( 6 twelfths is equal to 3 sixths )
Step-by-step explanation:
multiply both sides of 3/6 by 2 to get the same denominator, doing that will get you 6/12
Answer:
6 copies
Step-by-step explanation:
Step 1: Convert 1 twelfth to an expression
1 twelfth is the same thing as 1/12
Step 2: Convert 3 sixths to an expression
3 sixths is the same thing as 3/6
Step 3: Get common denominators
The lowest common denominator between 1/12 and 3/6 is 12
[tex]\frac{1}{12}[/tex] → [tex]\frac{(1 * 1)}{(12 * 1)}[/tex] → [tex]\frac{1}{12}[/tex]
[tex]\frac{3}{6}[/tex] → [tex]\frac{(3 * 2)}{(6*2)}[/tex] → [tex]\frac{6}{12}[/tex]
Step 4: Find the amount of 1/12 there are in 6/12
In order to find out the copies, we need to add 1/12 x amount of times to get 6/12. We find that x is going to be 6. Therefore, there 6 copies.
[tex]\frac{1}{12}+\frac{1}{12}+\frac{1}{12}+\frac{1}{12}+\frac{1}{12}+\frac{1}{12} = \frac{6}{12}[/tex]
Answer: 6 copies
