The cylindrical container shown below can be completely filled with 24 litres of water. The base area of the container is 600 cm

Virty [35]

Answer:

40cm

Step-by-step explanation:

volume of a cylinder= πr²h

V=24litres, Area=πr²=600cm², height=?

converting litres to cm³

1litre=1000cm³

24litres= 24×1000

=24000cm³

24000=600× h

h= 24000/600

= 40cm

slavikrds [6]

Answer: c. 10

Step-by-step explanation:

Given : An independent-measures research study compares three treatment conditions using a sample of n = 5 in each treatment.

For this study, the three sample means are, M1 = 1, M2 = 2, and M3 = 3.

Grand mean = $\overline{X}=\dfrac{M1+M2+M3}{3}$ [All sample have equal elements]

$=\dfrac{1+2+3}{3}=2$

For ANOVA,

$SS_{between}=n\sum(M_i-\overline{X})^2$ , where i= 1, 2 , 3

$SS_{between}=5((1-2)^2+(2-2)^2+((3-2)^2)$

$SS_{between}=5((-1)^2+(0)^2+((1)^2)= 5(1+1)=10$

Hence,the value would be obtained for $SS_{between}=10$ .

hence, the correct answer = c. 10
