b=3m
Step-by-step explanation:
Answer:
9 cups
Step-by-step explanation:
3/4 cups of sugar for 14 cookies
There are 168÷14 = 12 set of 14 cookies in 168
So we need 12 times 3/4 sugar
12 × 3/4 = 9 cups of sugar needed
Answer:
9
Step-by-step explanation:
ratio problem
3/4 sugar/14 cookies = x sugar/168
126 = 14x
x = 9
Answer:
x^2+10x+21
Step-by-step explanation:
Blue box: x*x=x^2
Green box: x*3=3x
Purple box: 7*x=7x
Orange box: 7*3=21
x^2+(3x+7x)+21
Combine like term
A: x^2+10x+21
Answer:
-1, 1
13, 15
Step-by-step explanation:
x and x+2 are the integers
Roots of the quadratic equation are: -1 and 13.
So the integers pairs are: -1, 1 and 13, 15
Samples are randomly selected throughout the day
Products are put into groups and all are included from several randomly selected groups
Products are put into groups and some are randomly selected from each group
Answer:
Every 10th product in the line is selected
Step-by-step explanation:
Convenience sampling also available sampling, or nearest in reach sampling.
it is a type of non-probability sampling that involves the sample being drawn from a population that is in reach or that is easily at hand.
example. A questionnaire being distributed to people met in a mall.
for the manufacturing company in question, the first 10 product in line were the first set of product the machine will produce (at hand).
it is normally use to test run the operation of the machine.
Convenience sampling in manufacturing is best described as selecting every 10th product in the line for testing. It is a simple, quick, and cost-effective way to identify potential issues.
In the context of manufacturing, convenience sampling represents a type of sampling where samples are chosen because they are readily available or easy to obtain. In the provided choice list, the best description of convenience sampling is 'Every 10th product in the line is selected'. This method is chosen for its simplicity and speed. While it may not provide a comprehensive result since it won't cover all the various different scenarios, it is a cost-effective and time-efficient way of identifying potential issues in machine operations.

Answer:
It is necessary four parameters.
Step-by-step explanation:
Since the augmented matrix of the consistent system has rank equal to three then the number of free variables is (number of unknows)-rank then there are 7-3=4 free variables. This means that are necessary four parameter to specify all solutions.
