Answer: slope is 6/1. y intercept is 11
Step-by-step explanation:
y = mx + b
the slope is the m value and the y intercept is the b value.
Mean is the average of all the paychecks, so it will be: (56.05 + 41.50 + 22.5 + 52.9 + 49.85 + 31)/ 6
The mean is: $42.30. So on average she earns $42.30 each week.
We can find the median by arranging from smallest to larges so: 22.5, 31, 41.5, 49.85, 52.9 and 56.05. Since we have an even number of entries, we will take the average of the middle two entries: (41.5 + 49.85)/2
So the median is: 45.68 (rounded to the nearest tenth)
Mode is the number that appears the most in a given set. In this set we can see, that no number is repeated. Therefore there is no mode.
6. Rotate 180 degrees from origin and shift 5 units down.
7. Scale 2x at origin and reflect across the Y axis. The sizes are different so it’s similar
Equation 2: 3m = 4 + 4n
Step 1:
−3(m) = −3(8 + 2n) [Equation 1 is multiplied by −3.]
3m = 4 + 4n [Equation 2]
Step 2:
−3m = −24 − 6n [Equation 1 in Step 1 is simplified.]
3m = 4 + 4n [Equation 2]
Step 3:
−3m + 3m = −24 − 6n + 4n [Equations in Step 2 are added.]
Step 4:
0 = −24 − 2n
Step 5:
n = −12
In which step did the student first make an error?
Step 4
Step 3
Step 2
Step 1
Answer:
Step 3
Step-by-step explanation:
Hello
the student made a mistake in the step number 3.
let´s see
in the step number 1 he multiplied by -3 in order to add this new equation with equiation 2 and then eliminate the terms with m
Step one
-3(m)=-3(8+2n)
-3m= -24 - 6 n, it is ok
in step two he simplified, he did it well.
in the step 3 he added the equations
-3m = -24-6n
3m = 4 +4n
_____________
0 = -20-2n
he did not add properly -24+4, here , he made his first mistake.
step 4 is already wrong
continuing..to find n
0= -20-2n
20=-2n
n=-10
Have a great day
Answer:
15 miles/2 hours = 7.5 miles/hour
Correct equation: d = 7.5t
Given:
Total number of patches = 39
Total number of rows = 3
To find:
The number of patches in each row.
Solution:
We have,
Total number of patches = 39
Total number of rows = 3
We need to divide the total number of patches by total number of rows to find the number of patches in each row.
Therefore, the number of patches in each row is 13.
