Identify whether this will be normal distribution or skewed left or right? (Hint: find the five number summary and make a box plot)
O skewed left
O skewed right
O normal distribution
The distribution of set A is a normal distribution
The data in set A is given as:
1 3 3 2 4 0 4 3 3 5 2
Represent the dataset as a plot, as follows
0

Notice that the plot above increase from 0, then reaches a maximum at 3, and then decreases from 3 to 5
This implies that it follows a bell curve.
When a distribution follows a bell curve, such data is a normal distribution.
Hence, the distribution is a normal distribution

the perimeter of the triangle below is 38 units. Find the length of side WX. Write your answer without variables
Answer:
5.5
Step-by-step explanation:
Add each side of the triangle.
3z+z+1+4z-3 = 8z - 2
8z - 2 is equivalent to the perimeter.
Since you know the perimeter is 38 units, you can set 8z-2 to 38.
8z-2 = 38
Solve for z. Subtract 2 from each side.
8z = 36
Divide each side by 8.
z = 4.5
Now solve for side WX.
WX = z + 1
WX = 4.5 + 1
WX = 5.5

no solution
Answer:
All real numbers
Step-by-step explanation:
Answer:
C) all real numbers
Step-by-step explanation:
4(a + 3) = 12 + 4a
open the parenthesis
4*a + 3*4 = 12 + 4a
4a + 12 = 12 + 4a
subtract 4a from both sides of the equation
12 = 12
since 12 = 12 regardless of what x is the solution is all real numbers

Solve x3 = 64 over 27
Answer:
x= 4/3
Step-by-step explanation:
Answer:
Hope it helps
Step-by-step explanation:
So you want to get x by itself.
x3= [tex]\frac{64}{27}[/tex]
You could simplify
x3=2.37037037037
Then just divide 3 on both sides
x=0.79012345679
Or you can divide a fraction by a whole number and just divide the numerator and the denominator by 3.
x= [tex]\frac{21.3}{9}[/tex] or just 2.36666666667.
Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise. How much will she earn each hour after the raise?
Answer:
28.75
Step-by-step explanation:
We can do 15% of 25 which is 3.75. Add this on to 25, and get 28.75.
The amount she is earning each hour after the raise is $28.75 if Sanya currently earns $25.00 an hour at her job.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise.
The raise = 15 % of 25 = 3.75
Total after raise = 25.00 + 3.75 = $28.7
Thus, the amount she is earning each hour after the raise is $28.75 if Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise.

After 6 months of paying the subscription fee and buying 12 songs each month, Andrea will have spent a total of $67.59.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
To find the total cost of the songs,
= 12 songs × $0.80/song = $9.60
Then, the total cost of the subscription and the songs over 6 months:
= $9.99 + (6 × $9.60)
= $9.99 + $57.60
= $67.59.
So, after 6 months of paying the subscription fee and buying 12 songs each month, Andrea will have spent a total of $67.59.

Answer:
A. x ≥ -3 and x < 2, or -3 ≤ x < 2
Step-by-step explanation:
Remember solid dot means include, open dot means not include.
x ≥ -3: this means x is greater and equal (includes) -3.
x < 2: this means x is less than 2 and does not include it.
Answer:
A
Step-by-step explanation:
So on the number line you see a closed circle at -3 and an open circle at 2.
Closed circle represents it's either [tex]\leq[/tex] or [tex]\geq[/tex]. Open circle represents < or >.
So the first part has a closed circle at -3 and goes towards the right side. Since it does that, it would be [tex]x \geq -3[/tex].
The second part has an open circle at 2 and goes towards the left side. Since it does that, it would be [tex]x < 2[/tex].
To combine it together, it would get [tex]-3 \geq x < 2[/tex].
Since option A is [tex]x \geq -3[/tex] and [tex]x < 2[/tex], or [tex]-3 \geq x < 2[/tex], A would be the answer.

Show that Ajay is correct.

This says "4 Squared equals 16"

So... I looked up this question before asking BUT some people said it was wrong ???? so I wanted to get some second opinions.
Answer:
The GCF Of 9 and 12 is 3.
Step-by-step explanation: Okay so first lets multiply! 3x1 Is 3 3x2 is 6 and 3x3 is 9, 3 x 4 equals 12! Since they both can be divided by 3, Example 12 divided by 3= 4 9 divided by 3= 3, therefore they have a GCF of 3. Remember, this is the greatest factor, not Multiple.
