Answer:
Step-by-step explanation:
1) Find the Mean of all the numbers.
3+4+5+7+10+12+15=56
56/7=8 mean is 8
Now We Calculate Standard Deviation:
S=[tex]\sqrt{(3-8)^2+(4-8)^2+(5-8)^2+(7-8)^2+(10-8)^2+(12-8)^2+(15-8)^2}[/tex]
You take each number from the problem i.e 3,4,5...
and then you subtract the mean from it and then square it.
S=[tex]\sqrt{(-5)^2+(-4)^2+(-3)^2+(-1)^2+(2)^2+(4)^2+(7)^2}[/tex]
S=[tex]\sqrt{25+16+9+1+4+16+49}[/tex]
S=[tex]\sqrt{120}[/tex]
S=[tex]\sqrt{120}/7[/tex]
7 is the amount of data units given in the problem.
120/7=17.1428571429
[tex]\sqrt{17.1428571429}[/tex] =4.1403933560541

Can someone help PLSSSSSSSSSSSSSSSSSSSSSSSSS
Answer:
Mean = sum of all observed values / sum of frequency
Mean= (1*2 +2*2 + 3*2 + 4*1 + 5*2 + 6*1) / (2+2+2+1+2+1)
Mean = 32 / 10
Mean = 3.2
4: The angles of a triangle are in the ratio 3:4:5. What is the measure of the smallest
angle?
A. 15°
B. 30°
C. 45°
D. 750
Answer:
sum of all angle = 180
given angle = 3X, 4 X AND 5 X
3 X + 4 X+ 5 X = 180
12 X = 180
X = 180/ 12
X = 15
X= 15 IS apply to given angle.
3 X= 3 ×15 = 45
4 X= 4 ×15 = 60
5 X = 5 ×15 =75
ANS; The smallest angle is 45

What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Consider the equation: x^2=-8x-7
1) Rewrite the equation by completing the square. Write it as (x+c)^2=d or (x-c)^2=d
Here the equation: x^2=-8x-7
x^2 + 8x + 7 = 0
Where a = 2, b = 8 , c = 7
(x+c)^2 = d or (x + 7)^2 = 16
(x-c)^2=d or (x - 7)^2 = 16

12. Two trains, Train A and Train B, weigh a total of 312 tons. Train A is heavier than Train B. The difference in their weights is 170 tons. Use elimination to solve the system of equations to find the weight of each train. a + b = 312 a-b= 170 a + b = 312 a - b = 170
Answer:
a = 241
b = 71
Step-by-step explanation:
a + b = 312 (#1)
a - b = 170 (#2)
(#1) + (#2) = 2a = 482.
a = 482 / 2 = 241.
b = 312 - 241 = 71.
