Is there more wood in a 60​-foot-high tree trunk with a radius of 2.2 feet or in a 50​-foot-high tree trunk with a radius of 2.6
Sladkaya [172]

Answer:

V₂=1061.85 ft³

Step-by-step explanation:

To determine where more wood is found, just find the volume of each log and see which one has the largest volume

knowing that the volume of a straight cylinder is

V=πR²h, where R=radius and h=height

V_{1}=\pi  (2.2)^{2}60= 912.31ft^{3}\\V_{2}=\pi  (2.6)^{2}50= 1061.85ft^{3}

As we can observe

V₂>V₁

.. a)
djyliett [7]

Answer:

1100

Step-by-step explanation:

price = 1500

discount= 15%

15% of 1500 = (15/100)*1500= 15*15= 225

so selling price = 1275

profit is selling price - cost price

1275 - CP = 175

CP = 1275-175= 1100

I didn't understand the calculator part of the question

Some researchers claim there is an association between taking vitamins and gaining weight. They took a random sample of people l
netineya [11]

Answer:

The probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47

Step-by-step explanation:

                                       Has Gained Weight        Has Not Gained Weight

Does not take vitamins                          52                                   19

Takes one vitamin per day                    35                                   49

Takes more than one vitamin per day 72                                    80

We are supposed to find the probability that he or she has gained weight, given that he or she takes more than one vitamin per day

A= he or she has gained weight

B=he or she takes more than one vitamin per day

P(A|B)=\frac{P(A \cap B)}{P(B)}

A \cap B = 72

B = 72+80=152

So,P(A|B)=\frac{72}{152}=0.47

So, Option C is true

Hence the probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47
