Answer:
1600 items should not be defective
Step-by-step explanation:
To determine the number of items that are not defective, we multiply the number of items we have by the probability that they are not defective.
Not defective items = items * probability
= 2000 * 4/5
1600
Answer:
Your answer of option b is right.
Step-by-step explanation:
Given that a sinesoidal function has maximum 12 and minimum -6
Hence centre line would be average of these two.
Centre line is
i.e. f(x) = a sin (bx+c)+3
Since amplitude = 12-3 =9 we have a = 9
i.e. f(x) = 9 sin (bx+c)+3
Frequency is given as 3, period = 1/3
This gives b = 6pi
f(0) = y intercept =
9sin(c)+3 =3
This gives c=0
Hence correct equation is
Answer: 2 grams
Step-by-step explanation:
To find a residual you must take the predicted value and subtract it from the measured value.
predicted value; 15
measures value; 17
17-15=2
Answer:
−3x^2-12x+63
Step-by-step explanation:
simplify-3(x-3) you should get -3x+9.
then use foil to get (-3x+9)(x+7)
you multiply -3x with (x+7) and tou should get (-3x^2-21x)
then multiply 9 with (x+7) and you should get (9x+63)
now you should have the numbers: -3x^2, -21x, 9x, and 63.
combine like terms: add 9x to -21x and tou will get -12x.
Now place the numbers in the correct order: variables with exponents, then nirmal variables, then non variables
