I just took the quiz, the answer is A: Critical values=0.312; there is sufficient evidence to support a claim of a linear correlation between before-and-after weights.
The sequence is geometric because the units are changing the same amount each time. Hope this helps!
Answer: x= 18
Step-by-step explanation:
90+25+3x+11= 180
126+3x=180
3x= 54
x= 18
3(18)+11
65
Answer:
A) y = 8.63 x
B) $224.38
Step-by-step explanation:
The the average monthly cost = (147.98+152.17+165.63)/3 = $155.26
So, For 18 employees the average monthly cost = $155.26
Let the equation that can be used to estimate y, the average monthly cost, in dollars, to buy lunch for x employees. ⇒ y = mx
For x = 18 , y = $155.26
So, m = y/x = $155.26/18 ≈ $8.63
∴ y = 8.63 x
To find the total cost for 26 employees.
∴ x = 26
∴ y = 8.63 * 26 = 224.38
The total cost of a monthly lunch for 26 employees = $224.38
Answer:
90 cents or $0.90
Step-by-step explanation:
To find the answer, we need to find UNIT RATE
In this equation, to find unit rate, divide $4.50 (4.5) by 5 to get your answer
When we do this, we get an answer of…
90 cents!
