Store A will cost $1.28
lora16 [44]3 years ago
4 0

Answer:

A: Store A will cost about $1.28 less

Step-by-step explanation:

Okay, let's find the unit rate of cost. To find that for store A, we divide 7.26 by 3, which gets us 2.42. For store B, we need to look for the first intersection. We find that at (20, 50). Let's divide 50 by 20. That gets us 2.50. Let's multiply 2.42 and 2.50 by 16. That gets us 38.72 for store A and 40 for store B. Let's subtract 38.72 from 40. That gets us 1.28. That means store A costs $1.28 less than store B. That makes our answer A.

Which best defines force?(1 point)
Strike441 [17]

Answer:

Your answer is, a push or pull applied to an object

<u>Step-by-step explanation:</u>

  • In physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
  • An impact of it high force or shock applied over a short time period when two or more bodies collide. Such a force or acceleration usually has a greater effect than a lower force applied over a proportionally longer period.

What is the value of 6(2b-4) when b =5
Sindrei [870]

Answer: The value of 6(2b-4) is 36.


Step-by-step explanation:

Given expression: 6(2b-4)

To find the value of 6(2b-4) at b= 5, we need to substitute the b=5 in the expression, we get

6(2(5)-4)\\=6(10-4).......[\text{solve parentheses}]\\=6(6)\\=6\times6=36

\\\Rightarrow6(2(5)-4)=36

Therefore, the value of  6(2b-4) is 36, when b=5.

Assume a random sample of size n is from a normal population. Assume a single sample t test is used to for hypothesis testing. T
valentinak56 [21]

Answer:

True

Step-by-step explanation:

Type I and Type II are not independent of each other - as one increases, the other decreases.

However, increases in N cause both to decrease, since sampling error is reduced.

A small sample size might lead to frequent Type II errors, i.e. it could be that your (alternative) hypotheses are right, but because your sample is so small, you fail to reject the null even though you should.

How do you figure out if one fraction is more/larger than another fraction?
SOVA2 [1]
There are several ways,
One, which is easiest, is to divide them, if the result is greater than 1, then the fraction at the numerator is larger. If the answer is less than 1, then the fraction at the denominator is larger.
Another way, is to try making both fractions have the same denominator and compare; the one with greater numerator is the larger fraction.

Hope this helps!
