Answer: D. 0.981
Step-by-step explanation:
Step 1: For the given data table on x^2
We square all values given to us
Step 2: we repeat Same for Y^2 table too.
Step 3: XY table we multiply x and y
Step 4: we make a summation of them all
Step 5: we input our summer value into our formula.
Step 6 : we arrive at our answer which is 0.981
Answer:
The cost of each juice boxes is $ 2
The cost of each hot dogs is $ 1 .
Step-by-step explanation:
Given as :
The amount which Bill pays for 3 juice boxes and 2 hot dogs = $ 8
The amount which Sarah pays for 2 juice boxes and 1 hot dogs = $ 5
Let The cost of each juice boxes = $ j
And The cost of each hot dogs = $ h
Now, According to question
3 j + 2 h = 8 .........A
2 j + 1 h = 5 ..........B
Now, solving the equations
2 × ( 2 j + 1 h ) = 2 × 5
or, 4 j + 2 h = 10
I.e ( 4 j + 2 h ) - ( 3 j + 2 h ) = 10 - 8
Or, ( 4 j - 3 j ) + ( 2 j - 2 h ) = 2
Or, j + 0 = 2
∴ j = 2
So , The cost of each juice boxes = j = $ 2
Now, Put the value of j in Eq A
I.e 3 × 2 + 2 h = 8
Or, 6 + 2 h = 8
Or. 2 h = 8 - 6
or, 2 h = 2
∴ h = = 1
So, The cost of each hot dogs = h = $ 1
Hence The cost of each juice boxes is $ 2
And The cost of each hot dogs is $ 1 . Answer
Answer:
At least 1.72 miles per day.
Step-by-step explanation:
Given: Goal of running is at least 50 miles in a month.
Andrea have already run 7 miles.
Days left in the month is 25.
As given, Andrea have already run 7 miles.
∴ Andrea need to run this month=
Days remaining this month is 25.
Now, finding miles need to run each day to meet her goal.
Miles need to run each day=
⇒ Miles need to run each day=
∴ Andrea need to run at least 1.72 miles to meet her goal this month.
