It is given that the sample size is 17.

So degrees of freedom is 16.

The confidence level is 80%.

Use the t table or a tool to find the critical t value as below:

The one tail t value for 80 percent confidence is 0.865 using t table.

So the critical value is 0.865.

a garden has 8 white roses and 11 red roses. one rose is plucked from the garden and then one more rose is plucked, without repl
lys-0071 [83]

Probabilities P(R/W) and P(W/R) don't have the same value

P(R/W): the probability of plucking a red rose the second time, given that for the first time white rose has been plucked

P(W/R): the probability of plucking a white rose the second time, given that for the first time red rose has been plucked

Probability:

Probability is synonymous with possibility. It is a mathematical branch that deals with the occurrence of a random event. The value ranges from zero to one. Probability has been introduced in mathematics to predict the likelihood of events occurring. Probability is defined as the degree to which something is likely to occur.

P(R/W)= p( red and white )/ P (white) and  P(W/R)=p( red and white )/ P (red)

as P(W)≠P(R)      

P(R/W)≠P(W/R)

Therefore, Probabilities P(R/W) and P(W/R) don't have the same value

A sample of marble has a volume of 6 cm3 and a density of 2.76 g/cm3. What is its mass?
Alenkasestr [34]

To solve for the mass of a substance is to simply get the product of volume and density, that is:

mass = density * volume

 

So calculating for mass:

mass = (2.76 g / cm^3) * 6 cm^3

<span>mass = 16.56 g</span>
