Answer:

80

Step-by-step explanation:

So if 50 tablets are made and 2 are defective then it’s 50:2. That means for every 50 tablets are made 2 are defective. And since 50 goes into 2000 40 times, you would multiply 40 x 2 to get 80, the number defective tablets

Answer:Convenience sampling

Step-by-step explanation:

This type of sample refers to convenience sampling or grab sampling or accidental sampling.

Convenience sampling is a non-probability type sampling that  includes the population which is nearby or available in your zone.

This type of sampling is handy when you need to know about a particular data in less time .Although the result may be somewhat biased because of a certain type of population may exist close to you.This method is most useful for Pilot testing.

SOMEBODY HELP ME WITH THESE PLEASE! I really need the help like NOW PLS!

93. g(n) = n - 4
f(n) = 2n^2 - 5n

then g(n) +f(n) = (n-4) + (2n^2 - 5n)
                                = n - 4 + 2n^2 - 5n
                                = 2n^2 -5n + n - 4
                                = 2n^2 - 4n -4


95. f(n) = -n+3
      g(n) = n^3 + 3n
Then f(n) . g(n) = (-n+3) . (n^3 + 3n)
                                 = -n^4 + 3n^3 - 3n^2 + 9n
 

97. f(x) = 3x+1
g(x) = 2x
For finding f(g(x)) we will plugin value of g(x) in place of x in f(x).
f(g(x)) = 3*(2x) + 1
                  = 6x + 1


99. f(n) = n - 3
g(n) = 2n^2 - 3n

g(-7) = 2*(-7)^2 - 3 * (-7) = 2* 49 + 21 = 98 + 21 = 119
f(g(-7)) = 119 - 3 = 116

Vlada [557]
As the equation is already given, we can just substitute the corresponding values in it!
Volume = 6 x 2 x 8
= 96 in3
So the answer is C. :)

What the answer to the question
Rzqust [24]

Answer:

Step-by-step explanation:

Remark

Begin by omitting all the pqrs bases that are raised the 0 power. Anything to the zero power = 1.

Multiply what is left.

Solution

Group One: p^-1

Group Two: p^-1 q^-3 s^-1

Group Three: q^-1r^-2s^-1

From groups 1 and 2 p is p^-2

From groups 2 and 3 q is q^-4

From groups  3 r is r^-2

From groups 2 and 3 s is s^-2

Notice that when the powers are - when the power is in the numerator, those powers become positive when they switch to the denominator.

Answer

\frac{1}{p^2 q^4 r^2 s^2}
