We know that the volume of a cone is given by the following relation:  
V = (pi * r^2 * h)/3 
 where r is radius and h is height of the cone
  In our case, radius is diameter divide by 2: 
 V = (pi * (8/2)^2 * 10) / 3 = 167.55 cubic inches 
 So the container holds 167.55 cubic inches

Answer:

We know that the volume of a cone is given by the following relation:  

V = (pi * r^2 * h)/3

where r is radius and h is height of the cone

 In our case, radius is diameter divide by 2:

V = (pi * (8/2)^2 * 10) / 3 = 167.55 cubic inches

So the container holds 167.55 cubic inches

Answer:

The blue liquid is toxic

Step-by-step explanation:

From the calculations I have done and attached to this problem

Null hypothesis:

H0 : p1 <= p2

Alternate hypothesis:

H1 : p1 > p2

^p1 = 0.925

^p2 = 0.2250

^P = (x1 + x2)/(n1+n2)

= 0.575

After calculating, I got test statistics = 6.33 ( check attachment)

P(z > 6.33) = 0.0000

In conclusion, our pvalue has been found to be less than the level of significance 0.05 so we reject null hypothesis and accept that we have enough sample evidence that the blue liquid is more toxic in comparison to white one.

Please check attachment for calculated test statistics.

A 100-gram sample of a radioactive isotope decays at a rate of 6% every week. How much of the sample will be left one year from
Dvinal [7]

4 grams sample will be left after 1 year

Step-by-step explanation:

The decay function for percentage decay is given by:

y =a (1-r)^x

Here,

a is the initial value

r is the rate

x is the number of time periods

Given

Initial value = 100 grams

Rate = 6% = 0.06

Time = 1 year = 52 weeks

Putting the values in the formula

y = 100 (1-0.06)^{52}\\y = 100(0.94)^{52}\\y = 4.00\ grams

Hence,

4 grams sample will be left after 1 year

Keywords: Decay, percentage

We need to find the tip , so,

→ 15% of the amount paid

→ $ 125 (15/100)

→ $ 18.75

Hence, the tip is of $ 18.75
