Answer:
(a)77.4bpm
(b)Mean of Sample 1 = 70.3 beats per minute.
Mean pulse of sample 2 = 70 beats per minute.
(c)
- The mean pulse rate of sample 1 underestimates the population mean.
- The mean pulse rate of sample 2 underestimates the population mean.
Step-by-step explanation:
(a)Population mean pulse.
The pulse of the nine students which represent the population are:
- Perpectual Bempah 64
- Megan Brooks 77
- Jeff Honeycutt 89
- Clarice Jefferson 69
- Crystal Kurtenbach 89
- Janette Lantka 65
- Kevin McCarthy 88
- Tammy Ohm 69
- Kathy Wojdya 87
The population mean pulse is approximately 77.4 beats per minute.
(b)Sample 1: {Janette,Clarice,Megan}
- Janette: 65bpm
- Clarice: 69bpm
- Megan: 77bpm
Mean of Sample 1
Sample 2: {Janette,Clarice,Megan}
- Perpetual: 64bpm
- Clarice: 69bpm
- Megan: 77bpm
Mean of Sample 2
The mean pulse of sample 1 is approximately 70.3 beats per minute.
The mean pulse of sample 2 is approximately 70 beats per minute.
(c)
- The mean pulse rate of sample 1 underestimates the population mean.
- The mean pulse rate of sample 2 underestimates the population mean.
Answer:
The number of times Seth attend in order for the benefit his father to buy the pass is 2.8 times .
Step-by-step explanation:
Given as :
The price for six month pass = $ 40
The cost of matinees with the pass = $ 1.00
The cost of matinees without pass = $ 3.50
Now, According to question
If we take matinees per day for six months so, number of matinees = 6 × 30 = 180
So, The cost of matinees for six month with pass at the rate $ 1.00 each = 180 × $ 1 + $ 40
I.e The cost of matinees for six month with pass $ 220
Now, Again
The cost of matinees for six month without pass at the rate $ 3.50 each = 180 × $ 3.50
I.e The cost of matinees for six month without pass at the rate $ 3.50 each = $ 630
So, The number of times Seth attend in order for the benefit = = 2.8
Hence The number of times Seth attend in order for the benefit his father to buy the pass is 2.8 times . Answer
Answer: 6
Step-by-step explanation:
I did it with LCM
-12(x-2) + (24x) = 4x(x-2)
using the quadratic formula, u get 6 and -1
