Answer:

Average employee [Mean] = 43.6

Step-by-step explanation:

Given:

Interval   Number of employee

25-35                      20

35-45                      7

45-55                      8

55-65                     15

Total                       50

Find:

Average employee [Mean]

Computation:

Interval     X[u+l]/2 Number of employee   fx

25-35         30           20                              600

35-45         40             7                              280

45-55         50            8                              400

55-65         60            15                             900

Total                           50                            2,180

Average employee [Mean] = Sum of fx / Sum of x

Average employee [Mean] = 2,180 / 50

Average employee [Mean] = 43.6

R varies inversely as v2 if r=120 when v=1 ,find r when v=10
makvit [3.9K]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ r = k/v^2

Substitute the values in:

120 = k/1^2

Multiply both sides by 1^2 to find k

k = 120

Substitute new values in:

r = 120/10^2

Solve:

r = 1.2

Write the equation of a circle with a center at (-1,2) and a radius of 7
Sever21 [200]

Answer:

(x+1)^2+(y-2)^2=49

Step-by-step explanation:

The standard form for the equation of a circle is (x-h)^2+(y-k)^2=r^2 where  r  is the radius, and the center is (h, k).

(h, k) = (-1, 2),  r = 7

(x-(-1))^2+(y-2)^2=7^2\\\\(x+1)^2+(y-2)^2=49
