Find the pattern 50, 52, 56, 62, ___, ___, ___. <br> please explain your answer
bixtya [17]
50, 52, 56, 62, 70, 80, 92
Let's start left to right
50 + 2 = 52
52 + 4 = 56
56 + 6 = 62
62 + 8 = 70
70 + 10 = 80
80 + 12 = 92
As you can see, the numbers are being added by 2 each time plus 2 more every time the number's place gets higher. For example, 52 is the 2nd number, and it's being added by 4. 62 is the 4th number, and it's being added by 8.

Find the mean, variance, and standard deviation of the sample with
azamat

Mean:-

\\ \tt\hookrightarrow \dfrac{\sum x}{n}=\dfrac{210}{10}=21

Standard Deviation:-

\\ \tt\hookrightarrow \sqrt{\dfrac{\sum x^2}{n}-(\sum x/n)^2}

\\ \tt\hookrightarrow \sqrt{\dfrac{5006}{10}-(21)^2}

\\ \tt\hookrightarrow \sqrt{500.6-441}

\\ \tt\hookrightarrow \sqrt{59.6}

\\ \tt\hookrightarrow 7.72

Variance:-

\\ \tt\hookrightarrow (S. D)^2=(7.72)^2=59.6

Can I get sum more help?
tensa zangetsu [6.8K]

Answer:

184.96

Step-by-step explanation:

V = (base × height) ÷ 3

base = pi × radius^2

2 × pi × radius = circumference

2×pi×r = 29.516

÷2 ÷2

pi×r = 14.758

÷3.14 ÷3.14

r=4.7

base= 3.14 × 4.7^2

= 69.36

V = (69.36 × 8) ÷ 3 = 184.96
