Study the following frequency distribution table.

m_a_m_a [10]

Answer:

Option C is correct.

f = 2

Step-by-step explanation:

The mean is the sum of variables divided by the number of variables

Mean = (Σfx)/(Σf)

xi | 15 | 17 | 20 | 30 | 10 + f

fi | 4 | 4 | 6 | 5 | 6

Σfx = (15×4) + (17×4) + (20×6) + (30×5) + [(10+f)×6] = 60 + 68 + 120 + 150 + 60 + 6f = (458 + 6f)

Σf = 4 + 4 + 6 + 5 + 6 = 25

Mean = 18.8

18.8 = (458+6f) ÷ 25

458 + 6f = 25 × 18.8 = 470

6f = 470 - 458 = 12

f = (12/6) = 2

Hope this Helps!!!

What is the distance between the two points (3,-3) and (6,1)

IrinaVladis [17]

Answer:

Distance between the points $(3,-3) \\\\$ and $(6,1)$ = 25

Step-by-step explanation:

The distance between two points in coordinate geometry can be find by using Distance formula.

If two points $(x_1,y_1)\\$ and $(x_2,y_2)$ are given then:

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

For points $(3,-3) \\\\$ and $(6,1)$

Distance=

$=\sqrt{(6-3)^2+(1-(-3))^2} \\\\=\sqrt{(6-3)^2+(1+3)^2} \\\\=\sqrt{3^2+4^2}\\\\=\sqrt{9+16}\\\\=\sqrt{25}\\\\=5$

The distance between the points is 25
