Answer:

B

Step-by-step explanation:

Because there is 1000 people in total, the percentage of people in the school B with cellphones would be solved by finding 408/1000=.408. If you round .408 to the nearest hundredth, because the thousandth place is 8, it would round up to .41

Answer:

\huge\boxed{\text{(B)}\ 0.41}

Step-by-step explanation:

This table will prove to be helpful to find the probability that a student has a cell phone and is from School B.

First off, we know that a total of 1000 students were interviewed, both from School A and from School B.

We also know that 479 of those 1000 were from School B (total on the right).

Looking further into School B, we can see that 408 students from school B have a cell phone.

Therefore, we can find the probability by finding 408 / 1000.

408 \div 1000 = 0.408 \approx 0.41

Therefore, the probability that a randomly selected student is from School B <em>and</em> has a phone is 0.41, or 41%.

Hope this helped!

A sculpture is shaped like a sphere with 4 cones attached to it. Several dimensions of the sculpture, in feet, are shown in the
suter [353]

volume of the center sphere = 4/3*PI*r^3

r = 3 ( given in the picture)

 so 4/3 * 3.14 *3^3 = 113.04 cubic feet

 volume of 1 cone: pi *r^2 *h/3

r = 3 and h=3 ( given in the picture)

so 3.14 * 3^2 * 3/3 = 28.26 cubic feet

 there are 4 cones so 28.26* 4 = 113.04 cubic feet


113.04 + 113.04 = 226.08 cubic feet

 rounded to nearest cubic foot = 226 cubic feet

What is a possible value of sin(theta) when cos2(theta)=0.73?
Sindrei [870]
We use the following trigonometric identity to answer the question:
 sin^ 2 (theta) + cos^ 2 (theta) = 1
 We substitute the values:
 sin ^ 2 (theta) + 0.73 = 1
 We cleared:
 sin ^ 2 (theta) = 1-0.73
 sin ^ 2 (theta) = 0.27
 Answer:
 a possible value of sin ^ 2 (theta) is:
 
c.0.26 (nearest option)
