Pls help me with this questions​
bazaltina [42]

Step-by-step explanation:

6a

Sn = n/2 [2a + (n-1) d]

(2Sn)/ n = 2a + (n - 1) d

2a + (n-1) d = (2Sn)/n

(n-1) d = (2Sn - 2a)/n

d =  \frac{2sn \:  - 2a}{(n(n - 1))}

d =  \frac{2(sn - a)}{ {n}^{2}  - n}

6b

d =  \frac{2(56 - 25)}{ {32}^{2}  - 32}

d = ¹/16

7a.

E = (mv²)/2 + mgh

E = m( v²/2 + gh)

E/m = v²/2 + gh

E/m - gh = v²/2

2(E/m - gh) = v²

so

v =   \sqrt{2( \frac{e}{m}  - gh)}

7b.

v =   \sqrt{2( \frac{4900}{20}  - 9.8 \times 15)}

v = 14 m/s

An experiment has a single factor with eight groups and five values in each group. a. How many degrees of freedom are there in d
pishuonlain [190]

Answer:

A) 7

B) 32

C) 39

Step-by-step explanation:

Degree of freedom is a means of checking how many values that are free to vary, while using a statistical method.

a) since the experiment has a single factor with eight critical values. Therefore;

C - F = degree of freedom among the group variation

8 - 1 = 7

b) The degree of freedom can be calculated, if the number of data; Therefore, number of data is;

N = 8 × 5 = 40

Then the degree of freedom in determining within group variation,

N - C Therefore;

40 - 8 = 32

C) The degree of freedom in determining the total variation is,

N - 1

40 - 1 = 39
