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!

(2x - 5) (5x - 10)
Use FOIL
10x² - 20x - 25x + 50

10x²  - 45x + 50
 

5( 2x² - 9x + 10)

     2x           -5 
      x             -2

5(2x - 5)(x -2)

make each equal to 0
2x - 5 = 0
x - 2 = 0

2x - 5 = 0                        x - 2 = 0
2x - 5 (+5) = 0                x - 2 (+2) = 0 (+2)
2x = 5                             x  = 2
x = 5/2

x = 5/2 , 2

hope this helps

Gradient of a straight line that is perpendicular to y = 4x + 2
lana66690 [7]
If a line's slope is \frac{a}{b}, the slope of the perpendicular line is -\frac{b}{a}
in this case, the given line has a slope 4, which is 4/1, so the perpendicular line has a slope/gradient -\frac{1}{4}
