Answer:

X=6 and Y=3

Step-by-step explanation:

Use SOHCAHTOA, SOH, Sin=Opposite/Hypotenuse, Therefore Sin60°=(3√3)/x ; Xsin60°=3√3 and Sin60° without using 4figuretable or calculator is √3/2, Now x=3√3 ÷√3/2 ;. therefore X=3√3×2/√3= 6. X=6 . Using Pythagoras theorem, 6²={(3√3)² +y²}. Y²= 36-27=9. Y=√9, Y=3. Therefore X=6 and Y=3.

Ksenya-84 [330]

Answer:

95% CI = ( 8.024 , 8.936 )

Step-by-step explanation:

Developing the exercise for a normal distribution then we have to calculate the degrees of freedom,

$df = n-1 = 14-1=13$

Where n, is our sample.

So in the table,

t = 2.1604

$95\% CI = (8.48 - \frac{2.1604*0.79}{\sqrt{14}} ,8.48 + \frac{2.1604*0.79}{\sqrt{14}} )$

$95\% CI = ( 8.024 , 8.936 )$

<em>**Assumptions:</em>

<em>Population is normal distributed</em>

common ratio= r= 2
last term=l= 1073741824
no. of terms in GP= 25

1073741824= a*r^n-1
1073741824= 2^24 * a
a= 1073741824/ 2^24
a=64 bacteria
