Well since 10 was added and the final number is 26, you first want to subtract 10 from 26:

16

And before 10 was added the number was cut in half, which means you now need to multiply by 2:

32

The original number is 32.

Amanda earned a score of 940 on a national achievement test that was normally distributed. The mean test score was 850 with a st
snow_lady [41]
<span>In math notation, we've done this: z = (X - μ) / σ = (940 - 850) / 100 = 0.90 where z is the z-score X is Vivian's score (940) µ is the mean (850) σ is the standard deviation (100) As you may know, in a normal distribution it's expected that about 68% of all observations will fall within 1 standard deviation of the mean, 95% will fall within 2 standard deviations, and 99% will fall within 3 standard deviations. 
940 lie before the first standard deviation, in which 16.5% is above it
since 940 is 0.9 from the mean and 0.1 from the first standard deviation
so above it is 17.5 % = 0.175 or about 0.18 </span>

If a current of 12 amps produces 480 volts across a resistor then how many volts does a 15 amp produce?​
LekaFEV [45]

Answer:

600 volts

Step-by-step explanation:

Given =

A = 12 ampere

V = 480 volts

A2 = 15 ampere

Solution =

R = V/I

= 480 / 12

= 40 ohms

R = V / I

V = R x I

= 40 x 15

= 600 volts
