We can express an equation to find the fraction of the catering order that is sandwiches or salads by summing up the fractions of the sandwiches and the salads, in this case, the fraction of the sandwiches is 5/12 and the fraction of the salads is 2/12, then the equation looks like this:
c = 5/12 + 2/12, option B is the correct answer
Answer:
17x^2 -22x -2
Step-by-step explanation:
- 5x^2 +6x -2 +4x (3x-7)
- 5x^2 +6x -2 +12x^2 -28x
- 17x^2 +6x -2 -28x
- Answer: 17x^2 -22x -2
Just so you know when I put (^) the number after it is a exponent.
Answer:
About 300 of every 1,000 cars assembled should have one or more defects
Step-by-step explanation:
From the sample of 100 cars, we can estimate the total number of defective cars, using a rule of three.
In this question:
For each 100 cars, 30 defective.
How many defective for 1000?
100 cars - 30 defective
1000 cars - x defective
Simplifying by 100
About 300 of every 1,000 cars assembled should have one or more defects
Does this provide convincing evidence that she is less than a 47% shooter?

Step-by-step explanation:
What is convincing evidence?
A proof is sufficient evidence or a sufficient argument for the truth of a proposition. The concept applies in a variety of disciplines, with both the nature of the evidence or justification and the criteria for sufficiency being area-dependent.
2 to the 10th power is the same thing as saying 2x2x2x2x2x2x2x2x2x2 which equals 1024
