Solved below.
Step-by-step explanation:
The data is provided for the starting salary (in $1,000) at some company and years of prior working experience in the same field for randomly selected 10 employees.
(a)
The formula to compute the correlation coefficient is:
The required values are computed in the Excel sheet below.
Thus, the sample correlation coefficient r is 0.9855.
(b)
The slope of the regression line is:
Thus, the slope of the regression line is 2.132.
(c)
The y-intercept of the line is:
Thus, the y-intercept of the line is 45.418.
(d)
The equation of the sample regression line is:
(e)
Compute the predicted starting salary for a person who spent 15 years working in the same field as follows:
Thus, the predicted starting salary for a person who spent 15 years working in the same field is $77.4 K.

For 1 flavor there are 9 topping
Therefore, for 5 different flavors there will be 5*9 choices
No of choices= 5*9
=45
The total nom of code that can be used is equal to 5+3 = 8
The answer is in the image
For every 8 cars there are 7 trucks
Therefore,
Cars:Truck=8:7
Answer is B)8:7
The solution is in the following image
F=ma
where F=force
m=mass
a=acceleration
Here,
F=4300
a=3.3m/s2
m=F/a
=4300/3.3
=1303.03kg
Speed=Distance/time
Here,
distance=15m
time=1sec
speed=15/1=15m/sec
Distance=Speed*time
time=15min=15*60sec=900sec
Distance travelled in 15 min=15*900=13,500m
=13500/1000 km=13.5Km
The answer is in the image
It will provide an instant answer!
