The probability of showing a 6 is 1/6. The other dice has to show a 1, 3 or 5. The probability for that is 3* 1/6 = 3/6 = 1/2. The resulting probability would be 1/6*1/2 = 1/12.

Bubba can mow a field in 8 hours. If Skeeter helps, they both can do it together in 3 hours. How long would it take Skeeter to m
ra1l [238]

When they work together, they do  1/3 of the job in one hour.

                   (Bubba) + (Skeeter) = 1/3 job/hour    

Subtract 'Bubba'
from each side:            Skeeter  =  (1/3 job/hour) - (Bubba)

Bubba, working alone, does  1/8 of the job in one hour.

                                      Skeeter  =  (1/3 job/hour) - (1/8 job/hour)

Can you subtract 1/8 from 1/3 ?

Before you can subtract, you'll need a common denominator.
I've got a nice one here . . .  24 .

                   1/3  =  8/24
                   1/8  =  3/24                                                         

                   Skeeter  =  (1/3 job/hour) - (1/8 job/hour)

                                  =  (8/24 job/hour) - (3/24 job/hour)

                                  =        5/24 job/hour .

Skeeter mows at the rate of  5/24 field/hour.

The other way to look at that is:     24/5 hour/field  =  4.8 hours .

Check:

         Bubba:     1/8     field per hour  =  0.125
         Skeeter:  1/4.8  field per hour  =  0.208333...     

         Together:                        (0.125 + 0.208333)

                                             =  0.333... field per hour

                                             =    3 hours/field .                  yay!

Xavier has a bag of 20 marbles. 8 are blue, 7 are red, and 5 are green. Xavier pulls out a marble, records what color it is, and
joja [24]

Answer:

0.1

Step-by-step explanation:

chance of pulling out a blue marble can be described as 8 equally probable outcomes (blue marbles) out of 20 equally probable outcomes (all marbles).

Similarly, the chance of pulling out a green marble is 5 out of 20.

In total, we have 8*5 (combinations of blue then green) outcomes out of 20*20 (any two marbles):

8*5 / (20*20) = 40 / 400 = 1/10 = 0.1

Write the if/else statement as the conditional expression that performs the same option result = x < y ? x * 5 : a b;
Semenov [28]

The conditional statement is

if x < y:

  result = x * 5

<h3>How to write the if/else statement as the conditional expression that performs the same option?</h3>

The statement is given as:

result = x < y ? x * 5

The above means that,

the variable result is assigned  x * 5 if x < y

So, the conditional statement is

if x < y:

  result = x * 5

Methods of statistics show that if a vegetarian diet had no effect on blood pressure, there would be less than 1 chance in 100 o
Andreas93 [3]

Answer: hi your question is incomplete  below is the complete question

answer:

The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.

The result has a practical significance because the large difference in mean values.

Step-by-step explanation:

Sample size = 85 followed a vegetarian diet

Period =  4 months,

Mean systolic blood pressure=  124 mmHg

Sample size = 75 followed non-vegetarian diet

Period = 4 months

Mean systolic Bp = 138 mmHg

Reasons/explanations

Given that p -value < 0.01  we will reject the null hypothesis

The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.

The result has a practical significance because the large difference in mean values.
