For the data set 7,5,10,11,12, the mean,x,is 9. What is the standard deviation
Answer:
It is 2.91547 You could round if you want.
Step-by-step explanation:
Answer: 2.61
Step-by-step explanation:
Given data (x) : 7,5,10,11,12
Mean of the data : [tex]\overline{x}=9[/tex]
Number of data values : n= 5
Now, [tex]\sum (x-\overline{x})^2=(7-9)^2+(5-9)^2+(10-9)^2+(11-9)^2+(12-9)^2[/tex]
i.e. [tex]\sum (x-\overline{x})^2=34[/tex]
Now, the standard deviation for this data is given by :-
[tex]\sigma=\sqrt{\dfrac{\sum (x-\overline{x})^2}{n}}\\\\\sigma=\sqrt{\dfrac{34}{5}}=2.60768096208\approx2.61[/tex]
Express 120% as a fraction in simplest form
Answer:
6/5
Step-by-step explanation:
120% turns into 120/100 and from there you simply
To convert 120% to a fraction in its simplest form, write it as 120/100 and then simplify the fraction by dividing both the numerator and the denominator by their greatest common factor, which is 20. This results in 6/5.
Explanation:To express 120% as a fraction in simplest form, you first write the value of the percent as a fraction with a denominator of 100. This is essentially how you convert percentages into fractions. This means that 120% becomes 120/100.
Next, you need to simplify this fraction. To simplify a fraction, you find the greatest common factor of both the numerator and the denominator and then divide each by that number. In this case, the greatest common factor is 20, so you divide both 120 and 100 by 20.
Doing so, the fraction becomes 6/5. Therefore, 120% can be expressed as the fraction 6/5 in simplest form.

find the area of the parallelogram
28 square units
14 square units
24 square units
48 square units
the answer is to your question is 48
Answer:
48 square units
Step-by-step explanation:
to find areas of unusual figures, we divide the section into more easy figures to find its area, in this case we can divide the parallelogram into two triangles, drawing a line from point D to point B
then we will have two triangles whose area is easier to find,let´s see the AB-BD-DA triangle
[tex]A=\frac{b*h}{2}[/tex]
b= 6 units (from -6 to zero)
h=8 units ( from -4 to 4)
[tex]A=\frac{6*8}{2} =24[/tex] square units
the area of the triangle DC-CB-BD is the same,
it's the same triangle but turned up, so we have a total area
At=24 square units* 2= 48 square units

Ruben worked in a union motorcycle factory for 20 years before returning to school to become a paramedic instead. He is 45 now. He has a pension from his previous employer, which would pay him $1500/month after his retirement at 65. Assuming he will live to 80 (which is slightly higher than the life expectancy for an American man) he would earn $270000 over 15 years. The company has stopped offering pensions and wants to buy out his pension today. Should Ruben accept a buyout offer of $125,000? Assume that he could invest the money at an interest rate of 3% with a monthly compounding.

The base of a triangle is 3 inches shorter than its height. The area of the triangle is 77 square inches. Find the base and the height
Explain Step-by-step please
I need the work
Answer:
The base is [tex]11\ in[/tex] and the height is [tex]14\ in[/tex]
Step-by-step explanation:
we know that
The area of the triangle is equal to
[tex]A=\frac{1}{2}(b)(h)[/tex]
where
b is the base of triangle
h is the height of triangle
In this problem
[tex]b=h-3[/tex] ----> equation A
[tex]A=77\ in^{2}[/tex]
so
[tex]77=\frac{1}{2}(b)(h)[/tex]
[tex]154=(b)(h)[/tex] -----> equation B
Substitute equation A in equation B
[tex]154=(h-3)(h)[/tex]
[tex]h^{2}-3h-154=0[/tex]
Solve the quadratic equation by graphing
The solution is [tex]h=14\ in[/tex]

Find the surface area 12cm 15cm 14cm 14cm
Answer:
1288
Step-by-step explanation:
Triangles on the top have surface area 15*14/2 there are four of them so multiply by four to get 420.
The rectangular sections all have area 12*14 except for the base. There are four of these equal sections, so the combined area is 672.
Lastly, the base has area 14*14, which is 196.
Summing all of these we get 1288
97) If the average of 3a and 4b is less than 50 and a is twice b, what

a) 8
b) 9
c)10
d)11
The average of [tex]3a[/tex] and [tex]2b[/tex] satisfies
[tex]\dfrac{3a+4b}2<50[/tex]
Then
[tex]a=2b\implies\dfrac{3(2b)+4b}2=5b<50\implies b<10[/tex]
[tex]a=2b[/tex], so if [tex]a[/tex] must be an integer, then the largest integer value it can take on is 19 if [tex]b[/tex] can be a rational number (in which case [tex]b=9.5[/tex]) or 18 if [tex]b[/tex] must also be an integer.
Given that none of the provided answer choices lists 18 or 19, I'd bet there's a typo and you're supposed to find the maximum integer value of [tex]b[/tex], in which case the answer would be B as the largest integer value would be 9.

-0.75-(-2/5)+0.4+(-3/4)
-0.75-(-2/5)+0.4+(-3/4) = -0.7 simplified, how I got this answer can be found below in 16 steps.
1 - First thing we want to do is remove the parentheses.
-0.75 - (-2/5) + 0.4 - 3/4
2 - Then we simplify, multiply -1 by -1.
-0.75 + 1 (2/5) + 0.4 - 3/4
3 - Then multiply 2/5 by 1.
-0.75 + 2/5 + 0.4 - 3/4
4 - Then we want to write - 0.75/1 as a fraction with a common denominator, we do this by multiplying by 5/5.
-0.75/1 * 5/5 + 2/5 + 0.4 - 3/4
5 - Then we write each expression with a common denominator of 5, we multiply each one by a factor of one.
-0.75 * 5/1*5 + 2/5 + 0.4 - 3/4
6 - Then we multiply 5 by 1.
-0.75 * 5 / 5 + 2/5 + 0.4 - 3/4
7 - Then we combine the numerators over the common denominator.
-0.75*5+2/5+0.4-3/4
8 - We multiply -0.75 by 5.
-3.75 + 2/5 + 0.4 - 3/4
9 - Then we add -3.75 and 2.
-1.75/5+0.4-3/4
10 - And then we divide -1.75 by 5.
-0.35 + 0.4 - 3/4
11 - Then add -0.35 and 0.4.
0.05 - 3/4
12 - We then write 0.05/1 as a fraction with a common denominator, we do this via multiplying it by 4/4.
0.05/1 * 4/4 - 3/4
13 - Then we write each expression with a common denominator of 4, through multiplying each by a factor of 1.
0.05 * 4/4 - 3/4
14 - We combine the numerators over the common denominator.
0.05 * 4 - 3 / 4
15 - We simplify.
-2.8 / 4
16 - Then we divide -2.8 / 4
The final answer is -0.7
Circle Y has a center at (2,3) and a radius of 4. Circle Z has a center at (2,−3) and a radius of 10. What is the scale factor of all radii of circle Y to all radii of circle Z?
Final answer:
The scale factor of all radii of circle Y to all radii of circle Z is 0.4.
Explanation:
To find the scale factor of all radii of circle Y to all radii of circle Z, we can compare their radii.
Circle Y:
Center: (2,3)
Radius: 4
Circle Z:
Center: (2,-3)
Radius: 10
The scale factor is determined by comparing the radii of the two circles. The radius of circle Y is 4 and the radius of circle Z is 10. To find the scale factor, we divide the radius of circle Y by the radius of circle Z: 4/10 = 0.4.
Therefore, the scale factor of all radii of circle Y to all radii of circle Z is 0.4.

Is 1+4(3x-10)-12x equivalent to -9 ?
After distributing the multiplication and combining like terms, the expression 1+4(3x-10)-12x simplifies to -39, which proves it is not equivalent to -9.
To determine if the expression 1+4(3x-10)-12x is equivalent to -9, we need to simplify the expression first. Let's do that step by step:
Distribute the 4 into the parentheses: 1 + 4*3x - 4*10 - 12x.Simplify the multiplication: 1 + 12x - 40 - 12x.Combine like terms: The 12x and -12x cancel each other out, leaving 1 - 40.Simplify the remaining expression: -39.After simplifying the expression, we end up with -39, which is not equivalent to -9. Therefore, the given expression 1+4(3x-10)-12x is not equivalent to -9.
