The probability that at least 40 rolls are necessary is 4/15.

What is probability?

Probability shows the likelihood of an event happening.  it can be calculated by dividing the number of outcomes of an event by the total number of possible outcomes or sample space. Probability is equal to '1' when the event is certain to occur. i.e P =1. It is less than '1' when it is not likely to occur. i.e P< 1

Probability P=no. outcomes/total no. of the possible outcomes

From the question;

No of out comes=40

No. of total possible outcome=150

Therefore probability P= 40/150

The radius of the cone is 10√(3/πh) inches when the volume of the cone is 100 cubic inches.

According to the question,

We have the following information:

Volume of cone = 100 cubic inches

We know that the following formula is used to find the volume of cone:

Volume of cone = π[tex]r^{2}h/3[/tex] where r is the radius of the cone and h is the height of the cone

π[tex]r^{2}h/3[/tex] = 100

Now, using the cross multiplication method:

π[tex]r^{2}[/tex]h = 100*3

Dividing both sides of the equation by πh:

[tex]r^{2}[/tex] = 300/πh

r = 10√(3/πh) inches

We can also solve it further by putting the value of π.

Hence, the radius of the cone is 10√(3/πh) inches when the volume of the cone is 100 cubic inches.

The compound interest is quaterly then answer is $266,022.2639 and when it is in continuously then answer is $275,579.4095

Quarterly compounding is what?

Compounding quarterly is the term used to describe the amount of interest that is earned on a quarterly basis on a savings account or investment where the interest is also reinvested. As most banks offer interest income on the deposits, which compounds quarterly, this information is useful in computing the fixed deposit income. It can also be used to figure out any revenue from money market instruments or other financial products that pay quarterly income.

What Does Constant Compounding Mean?

If compound interest is calculated and reinvested into the balance of an account across an essentially unlimited number of periods, continuous compounding is the mathematical limit that compound interest can reach. While this is not attainable in practice, the concept of continually compounded interest is crucial in finance. Given that most interest is compounded on a monthly, quarterly, or semiannual basis, this is an extreme example of compounding.

Both function in item I is decreasing, and the function in item II is increasing.

What is function?

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.

What is domain?

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

What is range?

The difference between the lowest and highest values in a list or set is known as the range. Put all the numbers in order before determining the range. The lowest number should then be subtracted from the highest. The range of the list is provided in the response.

1) As shown in the I that the function is in 3rd quadrant so thats why it decreases.

The price of one pear is $0.85

Cramer's rule is one of the useful methods used for solving a system of equations. In this method, the values of the variables in the system are to be calculated using the determinants of matrices. Thus, Cramer's rule is also known as the determinant method.

Given that: John buys 7 apples and 4 pears for $7.25 and at the same prices, Hayley buys 5 apples and 9 pears for $10.40

We will use this given information to form equations in matrices form. Let a and p represent the prices of one apple and one pear respectively.

The equation is:

7a + 4p = 7.25

5a + 9p = 10.40

The matrix formed is:

[tex]C=\left[\begin {array}{ccc}7&4\\5&9\end{array}\right][/tex] ,   [tex]b=\left[\begin {array}{ccc}7.25\\10.40\end{array}\right][/tex]

Find the determinants,

D =  (7 x 9) - (5 x 4) = 43

Da =  (7.25 x 9) - (10.40 x 4) = 23.65

Dp =  (7 x 10.40) - (5 x 7.25) = 36.55

a = Da/D = 23.65/43 = 0.55

p = Dp/D = 36.55/43 = 0.85

Answer: dont be rude

Step-by-step explanation:

Using the z-distribution to test the hypothesis, it is found that:

1. You would not like to continue the game, as in each trial you are losing.

2. The p-value is of 0.0023.

3. The low p-value means that there is enough evidence to conclude that the coin is biased.

At the null hypothesis, it is tested if there is not enough evidence that the coin is biased, that is, the proportion of heads is of 0.5, hence:

[tex]H_0: p = 0.5[/tex]

At the alternative hypothesis, it is tested if there is enough evidence that the coin is biased, that is, it has a proportion of heads lower than 0.5, hence:

[tex]H_1: p_1 < 0.5[/tex]

The test statistic is given by the equation as follows:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which the variables are listed and explained as follows:

The values of these parameters are given as follows:

[tex]\overline{p} = \frac{0}{8} = 0, n = 8, p = 0.5[/tex]

Hence the test statistic is:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0 - 0.5}{\sqrt{\frac{0.5(0.5)}{8}}}[/tex]

z = -2.83.

Using a z-distribution calculator, and considering a left-tailed test, as we are testing if the proportion is less than a value, with z = -2.83, the p-value is of 0.0023.

Since this p-value is less than the standard significance level of 0.05, it means that there is enough evidence to conclude that the coin is biased towards tails.

Answer:

  B

Step-by-step explanation:

You want to know the 15% down payment, the mortgage amount, the value of 1 point, and the total interest cost for a 6.5% 30 year loan on a $210,000 home.

The answer choices all have the down payment as $31,500 and the loan value as $178,500. A "point" is one percent of the loan value (not the home value), so ...

  1 point = 0.01 × $178,500 = $1785 . . . . . . eliminates choices A and C

The difference between choices B and D is in the value of the interest paid. Your experience with 30-year loans in this interest rate range tells you that the interest paid is between 1 and 2 times the loan value. That is, the chice $227,667 is more likely correct than the choice $406,167.

Comparing these two numbers, we see they differ by 178,500, which is the value of the loan. That is, we can guess that 406,167 is the total amount repaid, not just the interest.

Answer choice B is the only one that makes sense.

If you like, you can work the problem.

  down payment = 15% × $210,000 = $31,500

  loan amount = $210,000 -31,500 = $178,500

  one point = 0.01 × $178,500 = $1785

The monthly payment is found using the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

  A = 178500(0.065/12)/(1 -(1 +0.065/12)^(-12·30)) ≈ 1128.24

The monthly payment amount is about $1128.

So, the total repaid is 360 payments of $1128.24, or $406,167.

The interest paid is this amount less the principal:

  interest paid = $406,167 -178,500 = $227,667
