5 + 8 + 1 + 2 + 10 = 26 (divided by) 5 = 5.2
The mean and the standard deviation of the data set is 5.2 and 3.429.
What is Arithmetic Mean?The arithmetic mean is the average of a sum of numbers that shows the centre tendency of the numbers' position. It is frequently used as a parameter in statistical distributions or as a result of an experiment or a survey to summarise the findings.
We have,
Data: {5, 8, 1, 2, 10}.
So, the mean of data
= (5+ 8 + 1 + 2 +10)/ 5
= 5.2
Then, the Value of Deviations
-0.2, 2.8, -4.2, -3.2, 4.8
So, the variance is
= (0.04 + 7.84 + 17.64 + 10.24 + 23.04) / 5
= 11.76
And, Standard deviation is
= 3.429

I need to know the answer to the question
Answer:
X=4
Step-by-step explanation:
Answer and Step-by-step explanation:
To get x, we need to put everything on the right. We start off by multiplying each side by 3.
3 × [tex](\frac{7+2x}{3} ) =[/tex] 5 × 3
7 + 2x = 15
Now, we subtract 7 from each side.
(7 + 2x) - 7 = 15 - 7
2x = 8
Finally, we divide each side by 2.
2x ÷ 2 = 8 ÷ 2
x = 4
The answer to this equation is x = 4.

Caleb a organizado en si horario personal 6,5 horas de tiempo libre al día. Como desea ser un futbolista profesional, usa 6/13 de su tiempo libre para hacer ejercicios distintos para fortalecer su cuerpo, y el resto del tiempo libre juega fulbito con sus amigos de la comunidad. ¿Cuantas horas a la semana dedica Caleb para fortalecer su cuerpo y jugar fulbito?

Linear
Exponential
Quadratic
Answer:
1. Exponential
2. Linear
Step-by-step explanation:
1. Exponential
Principal = 15000
Rate, r = 6.5% compounded annually
A = P(1 + r)^t
A = 15000(1 + 0.065)^t
A = 15000(1.065)^t
2. Linear
Let initial amount in bank = x
Amount added per week = 2
Number of weeks or period = t
A = x + 2t
