Answer:
Jayden's solution is incorrect.
Jayden divided 14 by 2 and then added 1.5
Jayden substituted the wrong value for a.
I will use 'hr' to mean hour and 'hrs' to mean hours.
<u>The airplane flies:</u>
200 miles per hr
400 miles per hr
600 miles per hr
Average speed = Total distance ÷ total time
= (200 + 400 + 600)miles ÷ 3hrs = 400miles/hr
Time = Distance ÷ Average speed
= 2000miles ÷ 400miles/hr = 5hrs
Answer:
y = -20
Step-by-step explanation:
Given that y varies directly with x it means changing x will also cause change in y
Mathematically it can be written as:
y∝x
Removing the proportionality symbol
y = kx
Given y=25 when x=5 Putting the values
Now
We have to find the value of y when x = -4
Putting x=-4
Hence,,
y = -20
Answer:
<u>23 consumer.</u>
Step-by-step explanation:
Given:
Number Of Responses for Thirsty = 49
Number Of Responses for Clean = 24
Number Of Responses for Strong Ones = 15
Number Of Responses for PowerWash = 12
So,
The total number of Responses = 49 + 24 + 15 + 12 = 100
So, the probability to prefer PowerWash = 12/100 = 0.12
For a group of 195 consumers:
prediction to prefer PowerWash paper towels = 0.12 * 195 = 23.4
So,
The number of consumers prefer PowerWash paper towels = <u>23 consumer</u>
