A number cube is rolled. What is the probability that a number greater than 4 will be rolled?

The probability that a student will take no more than 40 minutes to complete tee examination is 0.00.

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Given:

The length of time it takes students to complete a statistics examination is uniformly distributed and varies between 40 and 60 minutes.

We have to find the probability that a student will take no more than 40 minutes to complete the examination.

As the time required to complete the statistics examination is uniformly distributed and varies between 40 and 60 minutes so no any student will take less than 40 minutes to complete the examination.

P(X ≤ 40) = 0   where 40 ≤ x ≤ 60

Hence, the probability that a student will take no more than 40 minutes to complete tee examination is 0.00.

What is the t - test?

When the population standard deviation is unknown, the student's t-test in statistics is a method for testing assumptions about the mean of a small sample taken from a population with a normally distributed sample size.

The independent samples t-test examines whether the two distinct values are different from one another when comparing two means, one of which is calculated from one set of scores and the other of which is calculated from another set of scores.

A two-sample t-test should be used to compare two independent means. The variances for both samples must be equal according to the test's premise.

Welch's test for unequal variances should be used if they are not.

Increase the probability of rejecting the null hypothesis and the size of the effect measurements.

Hence, Increase the likelihood of rejecting the null hypothesis and increase measures of effect size.

The test for breast cancer is not effective at identifying women who have breast cancer.

What is probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

It is given that, out of 2000 women, 16 are known to have breast cancer.

But, through the test, the women who do not have breast cancer are also testing positive and the women who have breast cancer are also testing negative.

So, the test for breast cancer is not effective at identifying women who have breast cancer.

Answer: You can watch 14 vines.

Step-by-step explanation: 1 2/5 is equal to 1 4/10

1 4/10 is equal to 14/10

So the amount of vines you could watch is 14 in 1 minute and 24 seconds.

The equation in slope-intercept form is found as; y = -x/2 + 5/2.

For the stated question.

Two point are-

(x1, y1) = (3,1)

(x2, y2) = (1,2)

Thus,

slope m = (y2 -y1)/(x2 - x1)

m = (2 - 1)/(1 - 3)

m = -1/2

Equation of line;

y - y1 = m(x - x1)

y - 1 = (-1/2)(x - 3)

y = -x/2 + 5/2

a)The 7-year growth factor for the amount on the loan is $4285.71 b)  7-year percentage change for the amount is 6.25% c) 1-year growth factor for the amount $612.244 and d) 1-year percent change for the amount is 0.894%.

a)We know very well that growth factor is ratio of difference of principal amount and loan amount to the time taken, or

Growth factor=(Final loan amount-Initial loan amount)/Total time

=>Growth factor=(78,000-48,000)/7

=>Growth factor=30,000/7=$4285.71

b)To find the percentage change in amount, we need to use initial loan amount and the difference between two amounts, or

 percentage change=((78000-48000)/48000)×100

=>percentage change=[(30000)/48000)]×100

=>percentage change=300/48=6.25%

c)Now, we have already find the growth factor for 7 years, we need to find growth rate in 1 year. So, we use unitary method to find it

=>In 7 years growth factor is=$4285.71

  ∴In 1 years growth factor is=$4285.71/7=$612.244

d)In 7 years percentage change for the given amount is =6.25%

∴In 1 year percentage change for the given amount=6.25/7=0.894%

If the mean of the five values is equals to 64 then the sum of x values i.e., ∑x is 320.

Arithmetic mean:

Arithmetic mean is simply called mean or average. To calculate the arithmetic mean of a set of values, we need to add all the values and then divide the sum by the number of values in the set.

X-bar = ( a₁ + a₂ + -----+ aₙ )/n

Here, there are n items in the set, and each item is represented by one of the a's.

We have given that,

Mean of 5 values , X-bar = 64 , n = 5

we have to calculate the sum of x i.e ∑x

Using Arithmetic mean formula,

sum of x , ∑x = X-bar × n , where x is five values

The binomial probability is defined as the probability of exactly x successes on n repeated trials, with p probability.

The formula for binomial probability distribution is;

P(X = x) = nCx * p^(x) * (1 - p)^(n - x)

Where;

P(X = x) = binomial probability

x = number of times for a specific outcome within n trials

nCx = number of combinations

p = probability of success on a single trial

q = probability of failure on a single trial

n = number of trials

1) We are given;

p = 15% = 0.15

n = 10

Thus;

P(X = 2) = 10C2 * 0.15^(2) * (1 - 0.15)^(10 - 2)

P(X = 2) = 0.2759

2) Probability that more than 2 have used their phones to access the Internet is;

P(X ≥ 8) = P(X = 8) + P(X = 9) + P(X = 10)

Using binomial probability calculator, we have;

P(X ≥ 8) = 0.00001

4) Probability that no more than 5 have used their phones to access the Internet is;

The triangle has lengths of 59 feet, 66 feet, and 79 feet.

Let us represent the length of the shortest side of the triangle with x feet, and that of the other shorter side with y feet

The longest side will be (2x - 39) feet

The length of the other shorter side will give us the equation;

y + x = 2x - 39 + 46

so that by subtracting x from both sides, we have

y = 2x - x + 46 - 39

y = (x + 7) feet

From the question,

x + x + 7 + 2x - 39 = 204 feet {which is the perimeter of the triangle}

4x - 32 = 204 {collect like terms}

4x = 203 + 32

4x = 236

x = 236/4

x = 59 feet

Therefore, as the length of the shortest side of the triangle is 48 feet,
