Answer: in explanation
Step-by-step explanation
Sandi can perform 1/9 of the task in a day
Eva can perform 1/5 of the task in a day
Working together, they can perform
1/9 + 1/5 of the task per day
= 5/45 + 9/45 = 14/45 of the task in a day
or 45/14 days in the task = 3.2 days
So
It would take about 3.2 days to complete the task working togethe
You just have to reverse the operations
1. -48-8= -56
2. -56/3= -18.66
ANSWER = -18.66
let f=1
then
1^2+3(1)
=5
2(1)-1(5+1)(3)=19
hope this is the answer plz mark brillent thank you my friend
Answer:
∠ A = 59°, ∠ B = 48° , ∠ C = 73°
Step-by-step explanation:
The interior angles of a triangle sum to 180°
sum the 3 angles and equate to 180
x + x - 11 + 73 = 180
2x + 62 = 180 ( subtract 62 from both sides )
2x = 118 ( divide both sides by 2 )
x = 59
Then
∠ A = x = 59°
∠ B = x - 11 = 59 - 11 = 48°
∠ C = 73°
The slope of a linear regression is the rate of change of the line of the best fit
- The interpretation of the slope is that the wait time per staff is 1.62 minutes
- The slope value is realistic
The linear regression is given as:
y = -1.62x + 18
Where
- y represents the wait time
- x represents the number of staff
Using the above representations, the slope means that the wait time per staff is 1.62 minutes
Also, the slope value is realistic because time can be measured in decimals
