Answer:
b. $1 in price is associated with a decrease of $8,000 in sales
Step-by-step explanation:
Linear function:
A linear function has the following format:
In which m is the slope, which represents by how much y changes when x changes by 1.
ŷ = 50,000 − 8x
This means that 
, in thousands of dollars, so when the price x increases by 1, the sales will be decrease by $8,000, and thus, the correct answer is given by option b.
Answer:
458
Step-by-step explanation:
21*21.8 = 457.8
Answer:
0.648
No, that is not an unusually low number of correct guesses.
Step-by-step explanation:
Suppose you take a 15 question True or False quiz and you guess on every problem. You only get 3 correct. Then
- correct;
- o\incorrect.
The probability of getting 3 or fewer correct guesses is
Using the criteria that a number 3 is unusually low if P(3 or fewer) ≤ 0.05, we can state that 3 is not an unusually low number of correct guesses.
the slope-intercept form is y= 4x−2
Answer:
Points scored in a basketball game vary directly with shots taken.
This means that this question can be solved
by proportions, using a rule of three.
How many would she have scored if she takes 60 shots?
Using a rule of three:
50 points - 40 shots
x points - 60 shots
Applying cross multiplication:
4x = 50 × 60
Divide from both sides
x = 50 × 1.25 = 75
Answer is 75
Step-by-step explanation:
Here is a easier explanation if you didn't understand clearly:
It asked for how many 60 shots would score.
You would look at the first time he scored which is 50 and took 40 shots. Divide them
50 ÷ 40 = 1.25 or 1.5
So now you know each point scores 1.25 or 1.5
Now you multiply 1.25 or 1.5 with how many shots to see how much was scored and in this case 60 shots.
60 × 1.25 or 60 × 1.5
& They both end up equaling just the same, 75.
Hope it made sense :)
