What he has left in the bank is here :
(123.17 + 34.68) - 50 = 107.8
He still has $107.8 left in the bank and he has $50 in his pocket.
I hoped I helped!
Answer:
a1) 
a2)
b1) 
b2)
c) X is more likely to be within 1 GPa of 70 GPa in the random sample of part b because of the largeness in sample size and less scattering of data
Step-by-step explanation:
Mean value, 
Standard deviation, 
a1) sample size, n = 16
Mean of the sampling distribution of the sample mean = mean value, i.e.

a2) The standard deviation of the sampling distribution of the sample mean

b1) For sample size, n = 64
Mean of the sampling distribution of the sample mean = mean value, i.e.

a2) The standard deviation of the sampling distribution of the sample mean

c) X is more likely to be within 1 GPa of 70 GPa in the random sample of part b because it has a larger sample size, hence a decrease in the variability. This makes us easily determine the position of the sample around the population mean
Answer:
$105.5 for 16 hours at $6.59 per hour
Step-by-step explanation:
form the equation given, G=h(t) + p(c)
where G=Gross pay,
h= hourly wage
t=time worked
p=percent tip
c=cost of customer meals
we determine the gross pay by first determining the independent variables
h=$4.25, t=16 hours,

if we substitute values, we arrive at

to determine the per hour gross pay we have
105.5/16
hourly gross pay,G=$6.59
Answer:
The temperature decreased by 9 °F in <u>6 days.</u>
Step-by-step explanation:
Let the number of days it takes for the temperature to decrease by 9 °F be
.
Given:
Average daily temperature decreases by
°F.
Decrease of temperature in 1 day =
= 1.5 °F.
∴ Decrease in temperature in x days is
.
Now, as per question, decrease in temperature in 'x' days is 9 °F.
Therefore, 


Therefore, the temperature decreased by 9 °F in 6 days.
