Answer:
60 of 24 dollars each and 50 of 25 dollars
Step-by-step explanation:
x= 24 dollars
110 shares, total x at 24 dollars each
110-x at 25 dollars each
24x+25 (110-x)=2690
24x+ 2750 - 25x= 2690
-1x= -60
x= 60
24 multiplied by 60 =1440
2690-1440 =1250
1250 / 25 = 50

Answer:
The 95% confidence interval for the population mean daily protein intake is between 69.97g and 84.03g.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 77 - 7.03 = 69.97g.
The upper end of the interval is the sample mean added to M. So it is 77 + 7.03 = 84.03g.
The 95% confidence interval for the population mean daily protein intake is between 69.97g and 84.03g.
Answer:
Q. 2)Perimeter =2(l+b)
So,
2(8x-8 +8x)=80cm(Given in Question)
= 2*16x-8=80cm
16x- 8= 80 divided by 2,
16x=40+8=48
x=48 divided by 16
X=3
Q.1) Perimeter=2(l+b)
2(2x+8 +4x)=76cm(Given in Question)
2* 6x +8=76
6x+8= 76 divided by 2, 38
6x= 38-8, 30
x= 30 divided by 6 = 5
X=5
