You roll a die 4 times. What is the probability of rolling a 3 on all 4 times?
A.1/216
B.1/6
C.4/6
D.1/1296

Answer:

Step-by-step explanation:

Given,

Volume = 5600 sq.ft

Length = 35 ft

Width = 8 ft

Therefore,

By the problem,

[tex]height = \frac{volume}{length \times width} [/tex]

[tex] = > h = \frac{5600}{35 \times 8} ft[/tex]

=> h = 20 ft (Ans)

Answer:

r = 100 km/hr is the average speed of the car.

Step-by-step explanation:

The formula which relates distance d, time t, and speed or rate of travel r is:

d = rt.

We're given that the distance traveled d = 50 km and the time t traveled = 30 minutes = 1/2 hr. Substituting this given information into the distance-rate-time formula for d and t to find r, we get:

50 km = r(1/2 hr)

Now, dividing both sides by 1/2 hr, we have:

50 km/(1/2 hr) = [r(1/2 hr)]/(1/2 hr)

50 km/(1/2 hr) = r[(1/2 hr)/(1/2 hr)]

[50 km/(1/2)] km/hr = r[(1/2 hr)/(1/2 hr)]

50(2/1) km/hr = r[1]

100 km/hr = r[1]

r = 100 km/hr is the average speed of the car.

Answer:

The correct answer is C. 47 3/4 oz.

Step-by-step explanation:

Since Ricki caught ten fish, and the weights of the fish were 3 2/4 oz one of them, 4 1/4 oz three of them, 4 3/4 oz two of them, and 5 2/4 oz four of them To determine their total weight, the following calculation must be performed:

3 2/4 + (4 1/4 x 3) + (4 3/4 x 2) + (5 2/4 x 4) = X

3 2/4 + 12 3/4 + 9 2/4 + 22 = X

46 7/4 = X

47 3/4 = X

Therefore, the total weight of the fish was 47 3/4 oz.

Answer:

V = 20.64573mm^3

Step-by-step explanation:

a = 15/5 = 3

h = 4

V = (5/12) tan(54) h a^2

V = (5/12) tan(54) (4) (3)^2

V = 20.64573

Answer: C. Step 3

Step-by-step explanation:

Since we are informed that Ty tried to evaluate the expression step by step. The expression given is:

8x2x3

Step 1: =8x(2x3)

Step 2: =8x6

Step 3: =42

From the above, we can see that both step 1 and step 2 are correct but step 3 is wrong because 8 × 6 isn't equal to 42 but rather 48.

8 × 6 = 48 and not 42.

Therefore Ty's mistake is step 3.

Answer:

Volume of beach ball = 4176.2 inch³ (Approx.)

Step-by-step explanation:

Given:

Diameter of beach ball = 20 inches

Find:

Volume of beach ball

Computation:

Radius of beach ball = Diameter / 2

Radius of beach ball = 20 / 2

Radius of beach ball = 10 inches

We know that beach ball is a sphere shape

So,

Volume of beach ball = Volume of sphere

Volume of sphere = [4/3][π][r³]

Volume of beach ball = [4/3][π][r³]

Volume of beach ball = [4/3][22/7][10³]

Volume of beach ball = [1.33][3.14][1,000]

Volume of beach ball = 4176.2 inch³ (Approx.)

Answer:

The probability that the sample mean would be at least $39000 is of 0.8665 = 86.65%.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean $39725 and standard deviation $7320.

This means that [tex]\mu = 39725, \sigma = 7320[/tex]

Sample of 125

This means that [tex]n = 125, s = \frac{7320}{\sqrt{125}}[/tex]

The probability that the sample mean would be at least $39000 is about?

This is 1 subtracted by the pvalue of Z when X = 39000. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{39000 - 39725}{\frac{7320}{\sqrt{125}}}[/tex]

[tex]Z = -1.11[/tex]

[tex]Z = -1.11[/tex] has a pvalue of 0.1335

1 - 0.1335 = 0.8665

The probability that the sample mean would be at least $39000 is of 0.8665 = 86.65%.

Answer:

2249 / 540000

Step-by-step explanation:

Jobs arrival time = 8 jobs per hour

Service takes 3 minutes on average

Frame size = 5 second

capacity of each frame = 3 jobs

Determine the transition probability matrix for number of jobs in system

First step : find probability of job arrival

= 8 / ( 5 * 3600)

=  8 / 18000 =  1 / 2250

next : determine probability of service

= ( 3 * 5 )/ 3600

= 15 / 3600 = 1/240

Finally the transition probability matrix ( p10 )= { 1, 0}

=  probability of service(1 - probability of arrival)

 = 1/ 240 * ( 1 - 1 / 2250 )

= 1 / 240 * ( 2249 / 2250 )

= 2249 / 540000

m(arc FE) = 166°

Step-by-step explanation:

By theorem of intersecting chords and tangent of a circle,

Measure of the angle formed by a chord and tangent intersecting on the circle measure the half of the intercepted arc.

m(∠GFE) = [tex]\frac{1}{2}\text{m (arc} FE)[/tex]

83° = [tex]\frac{1}{2}\text{m (arc} FE)[/tex]

m(arc FE) = 166°

Answer:

Step-by-step explanation:

Random samples on both cases  and

p∧o proportion of bags packaged on the old machine that are damaged

p∧n sample proportion of bags packaged on the new machine that are damaged

p∧c  =  ( p∧o + p∧n ) / (nO + nN )  

p∧o = 15 %      p∧o =  0,15         nO = 150

p∧o *  nO = 0,15 *150          p∧o *  nO = 22,5

p∧n  = 8 %      p∧n  = 0,08     nN = 200

p∧n*nN  = 0,08 * 200     p∧n*nN  = 16

Both  p∧n*nN  and   p∧o *  nO    are bigger than 5

Therefore both samples are big enough for the approximation of the binomial distribution to normal distribution

Answer is A

Answer:

= 2808.6%

"Percent" means "per 100" or "over 100". So, to convert 28.086 to percent we rewrite 28.086 in terms of "per 100" or over 100.

Multiply 28.086 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.

28.086/1×100/100=2808.6100

2808.6/100 is 2808.6 over 100 and means 2808.6 per 100. 2808.6 "per 100" means 2808.6 "percent" or 2808.6%

Therefore, we have shown that

28.086 = 2808.6%

Multiply by 100 and add the percent sign %

28.086 × 100 becomes 2808.6%

Move the decimal point 2 places to the right and add the percent sign %

28.086 becomes 2808.6%

I have to go so I cant finish 4 and 5 but I hope this helped

Step-by-step explanation:

1) this is based just on the results so we don't have to do any probability tree or anything. there are 25 groups overall and 19 of those 25 groups contain at least one senior. this is 76% and is over 2 thirds so it is likely

2) again this is based just on the results so we don't have to do any probability tree or anything. there are 25 groups overall and 5 of those 25 groups contain at least 2 freshmen. this is 20% and is under 1 third so it is unlikely

3)again this is based just on the results so we don't have to do any probability tree or anything. there are 25 groups overall and 2 of those 25 groups contain four students from the same grade level. this is 8% and so is  unlikely.
