Answer:
(c) x = 10
Step-by-step explanation:
The diagonals of a square cross at right angles, so the measure of angle KNJ is 90°.
90 = 10x -10
100 = 10x . . . . . add 10
10 = x . . . . . . . . divide by 10
The value of x is 10.
Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The mean is 
The standard deviation is
The sample size is n = 25
The combined resistance is 
Generally the sample mean is mathematically represented as

=> 
=> 
Generally the standard error of the mean is mathematically represented as

=> 
=> 
Generally the probability that a random sample of 25 of these resistors will have a combined resistance of less than 1010 ohms is mathematically represented as



From the z table the area under the normal curve to the left corresponding to 1 is


One solution because all you need to do us 2x-5y=17+6x-15=51
Answer:
Easy!
Step-by-step explanation:
All you have to do is.. Percentage = (number you want to find the percentage for ÷ total) × 100. Move the decimal point two places to the right to convert from a decimal to a percentage, and two places to the left to convert from a percentage to a decimal.
Hope this helps :)
