5(3x-7) = 20

15x-35 = 20

15x = 55

x = 3.666666

so 6(3.666666) -8 = 13.99999 round to 14

5(3x-7)=20
15x-35=20
15x=55
x=3 2/3

6(3 2/3)-8
22-8=14
so the answer is 6x-8=14

The following dataset represents the number of registered students for 60 college courses, sorted and arranged in rows of 5. Wha

Temka [501]

Answer:

Step-by-step explanation:

There are 60 data altogether.

Therefore, n=60

50th percentile = 50%*(n+1)

=50/100*(60+1)

=30.5

This implies that the 50th percentile is between the 30th and 31st data

30th data= 57 ; 31st data = 57

since they are the same figure, 50th percentage = 57

Each of the following integrals represents the volume of either a hemisphere or a cone, and the variable of integration measures

iris [78.8K]

Answer:

1. cone

radius, height = 2, 10

volume = 13.33

2. hemisphere

radius= 14

volume = 1829.33

Step-by-step explanation:

The region described has a radius r=2−y/5, therefore, the volume is a cone

radius, height = 2, 10

volume =

$\int\limits^{10}_0 {\pi ( 2-\frac{y}{5} )^2} \, dy \\=$

= 13.33

2. The region ∫14 0 π(196 - h^2) dh has a radius 196 - h^2, so the volume is a hemisphere

radius = 14

volume

= $\int\limits^{14}_0 {\pi (196 - h^{2} )} \, dh$

= $\pi (196h- \frac{h^3}{3}) |^{14}_0$

=1829.33
