Step-by-step explanation:

The probability that the two dice have the same number of spot(s) is 1/6 or 16.7%. This is because there are six possible outcomes when rolling a pair of dice: both dice having 1 spot, both dice having 2 spots, both dice having 3 spots, both dice having 4 spots, both dice having 5 spots, and both dice having 6 spots. Since the sum is less than 6, this eliminates the possibility of both dice having 6 spots. That leaves 5 possible outcomes, and each outcome has an equal probability of occurring. Therefore, the probability of both dice having the same number of spots is 1/6 or 16.7%.

Answer:

166.5 cm squared

Step-by-step explanation:

Multiply 11x11 =121

Multiply 7x6.5 =45.5 (we get the 7 because 18-11=7)

Then we add 121 and 45.5 and get 166.5

The area of this composite shape is 166.5 square cm

Composite figures are figures that has more than 1 shape. The given figure is made up of two rectangles.

The area of the shape is given as shown below;

Area = (11*11) + (7 * 6.5)
Area = 121 + 45.5

Area = 166.5 square cm

From the question, the sum of each of the geometric sequence are;

1)  31 3/4

2) 340

3) 11/16

4) -6, 12, -24

We have that;

Sn = a(1 -\(r^n\))/1 - r

Sn = 16(1 \(- (1/2)^7\))1 - 1/2

Sn = 16(1 - 1/128)/1/2

Sn = 16(127/128) * 2

Sn = 31 3/4

2) Un = a\(r^n\) -1

256 = \(4(4)^n-1\)

64 =\(4^n-1\)

\(4^3 = 4^n-1\)

n = 4

Sn= \(4(4^4 - 1)\)/4 - 1

Sn = 340

3) Since we have a5 then n = 5

Sn = 1(1 - (\(-1/2)^5\))/1 -(-1/2)

Sn = 33/32 * 2/3

The expression that represents the total price of buying g pounds of grapes, b pounds of bananas, and p pounds of pears is Total cost = $2.19g + $0.59b + $1.49p

In this case, we need to use the given prices per pound of each fruit to calculate the total cost of purchasing a certain amount of each fruit. We can do this by multiplying the price per pound by the number of pounds of each fruit we want to buy, and then adding up these values.

So, to create the expression, we can start by using the given prices to calculate the cost of each fruit:

Grapes: $2.19/pound

Bananas: $0.59/pound

Pears: $1.49/pound

Next, we can use the variables g, b, and p to represent the number of pounds of each fruit we want to buy. We then multiply each price by its respective variable to get the cost of each type of fruit:

Cost of grapes: $2.19/g x g = $2.19g

Cost of bananas: $0.59/b x b = $0.59b

Cost of pears: $1.49/p x p = $1.49p

Finally, we can add up the costs of all three types of fruit to get the total cost:

Total cost = $2.19g + $0.59b + $1.49p

Net rendering is a method of rendering a computer-generated animation or image on multiple computers over a network.

Net rendering is a method of rendering a computer-generated animation or image on multiple computers over a network. This technique allows a user to take advantage of the computing power of multiple computers to render a scene. To do this, the user would divide the scene into several parts, assigning each part to a different computer. The computers would then render each part of the scene independently, and then the results are combined into a single image. This process can significantly reduce the time required to render a scene, as the workload is distributed over multiple computers. For example, if it would normally take a single computer 10 minutes to render a scene, net rendering could reduce that time to 2 minutes.

There are different ways to approach this question, but one possible method is to conduct a one-sample t-test using the formula t = (M - μ) / (s / sqrt(n)), where M is the sample mean, μ is the population mean (null hypothesis), s is the sample standard deviation, and n is the sample size. With the given information, the t-value is (1.6 - 0) / (0.8 / sqrt(16)) = 8.

The degrees of freedom is n - 1 = 15. Using a t-table or a calculator, the p-value for a one-tailed test with 15 degrees of freedom and a t-value of 8 is much smaller than .05 (e.g., < .0005). Therefore, we can reject the null hypothesis and conclude that women find a sense of humor to be important in a long-term relationship at a .05 level of significance. The correct answer is b.

Test 2 is associated with smaller critical values. The critical values for a t-test depend on the level of significance, the degrees of freedom, and whether the test is one-tailed or two-tailed. In general, a smaller level of significance or a larger sample size leads to smaller critical values (i.e., it becomes easier to reject the null hypothesis). Since Test 2 has a larger sample size than Test 1, it is more likely to detect a significant effect (i.e., have a smaller Type II error rate), and therefore requires smaller critical values to achieve a .05 level of significance. The correct answer is b.

By using Binomial probability distribution, the mean number of adults who would have bank savings accounts is 32.

For every survey, there are only two possible outcomes.

First- they have bank savings accounts,

second- they do not.

So, by using the binomial probability distribution we can solve this problem.

Probability of exactly Y successes in ‘n’ repeated trials, with ‘p’ probability.

Probability = p

Successes repeated = n  times

The  value of the binomial distribution is:

E(Y) = n x p

In this problem, we have that:

p = 0.64

If we were to survey among 50 randomly selected adults, the mean number of adults who would have bank savings accounts is,

E(Y) when, n = 50

So,

E(Y)= n x p

Answer:

-21/3 < -1/4 < 21% < 0.75 < 4/5

Step-by-step explanation:

Answer:

b = 21

Step-by-step explanation:

If there are 5 arithmetic means between 5 and b and the last term is 25, then we can find the value of b by using the formula for the nth term of an arithmetic sequence:

a_n = a_1 + (n - 1)d

where a_n is the nth term, a_1 is the first term, n is the number of terms, and d is the common difference.

We know that there are 5 arithmetic means between 5 and b. Therefore, there are 7 terms in total (including 5 and b). We also know that the last term is 25. So we have:

a_7 = 25 a_1 = 5 n = 7

We can use these values to solve for d:

a_n = a_1 + (n - 1)d 25 = 5 + (7 - 1)d d = 4

Now that we know d, we can find b by using the formula for the fifth term:

a_5 = a_1 + (5 - 1)d a_5 = 5 + (4)(4) a_5 = 21

Therefore, b = 21.

The probability that their first child will be a phenotypically normal girl is 3/8 or 37.5%.

Lou Gehrig's disease, also known as amyotrophic lateral sclerosis (ALS), is typically considered as an autosomal recessive disease. This means that both copies of the gene responsible for the disease need to be inherited, one from each parent, in order for an individual to be affected by the disease.

Given that the woman and her husband are both carriers of the disease, they each have one copy of the mutated gene and one normal gene. The probability of passing on the mutated gene to their child is 1/2 for each parent since they are carriers.

To determine the probability of their first child being a phenotypically normal girl, we need to consider the inheritance pattern. Let's break it down:

Gender: The probability of having a girl is 1/2, as gender is determined by the combination of the father's sperm (containing either an X or a Y chromosome) and the mother's egg (containing an X chromosome).

Phenotypically normal: For the child to be phenotypically normal, they should inherit at least one normal gene from either parent. The probability of inheriting a normal gene from the mother is 1/2, and the same probability applies for inheriting a normal gene from the father.

Independence: The probability of having a girl and inheriting a normal gene are independent events, so we can multiply their individual probabilities to calculate the combined probability.

Therefore, the probability of having a phenotypically normal girl is:

Probability of being a girl × Probability of inheriting a normal gene

= (1/2) × (1/2)

= 1/4

However, we also need to consider the possibility of having a boy. The probability of having a phenotypically normal boy is also 1/4.

Adding the probabilities of having a phenotypically normal girl and a phenotypically normal boy, we get:

1/4 + 1/4 = 2/4 = 1/2        

Since the question specifically asks for the probability of having a phenotypically normal girl, we divide the probability of a phenotypically normal girl by the total probability of having a child:

(1/4) / (1/2) = 1/4 * 2/1 = 1/2 = 2/4 = 1/2

Therefore, the probability that their first child will be a phenotypically normal girl is 1/2 or 50%.

In this question, two houses have an initial value of $179,000, and the projected values are given in the tables for houses 1 and 2.

Part a:

If the absolute value of the change is always the same, it is linear.

If the rate is the same, it is exponential.

House 1:

We have that:

193,606.4 - 186,160 = 7446.4

201,350.66 - 193,606.40 = 7744.26

Let's try exponential:

\(\frac{193,606.4}{186,160} = 1.04\)

\(\frac{201,350.66}{193,606.40} = 1.04\)

For house 1, the rate of change is the same, and thus, it is exponential.

House 2:

212,000  - 201,000 = 201,000 - 190,000 = 11,000.

Absolute value of change is the same, so linear.

Thus, for house 1, an exponential function is used, as the rate of change is the same, and for house 2, as the absolute value of change is always the same, it is linear.

Part B

House a:

Exponential function, with initial value of $179,000, and exponential growth rate of 1.04 - 1 = 0.04. Thus:

\(f_a(x) = 179000(1+0.04)^x\)

\(f_a(x) = 179000(1.04)^x\)

House b:

Linear function, with initial value of $179,000, increasing by $11,000 each year. So

\(f_b(x) = 179000 + 11000x\)

Part c:

House a after 30 years:

\(f_a(30) = 179000(1.04)^30 = 580,568\)

House b after 30 years:

\(f_b(30) = 179000 + 110000(30) = 509,000\)

In 30 years, house a will have a value of $580,568, while house b will have a value of $580,568. House a will have a higher value, due to exponential growth.

To find a basis of the subspace that consists of all vectors perpendicular to both [1] [0] [0] [1] [-8] [-5] and [_] [3] [-2] [_], we first need to find the cross product of the two given vectors.

[1] [0] [0]
[1] [-8] [-5]
[_] [3] [-2]

The cross product of these three vectors is:

[0] [0] [-3]

This vector represents the normal vector to the plane that contains the two given vectors. Any vector that is perpendicular to both of the given vectors will lie in this plane and be orthogonal to this normal vector.

Thus, we can set up the following equation:

[0] [0] [-3] • [x] [y] [z] = 0

Simplifying this equation gives: -3z = 0
This tells us that z can be any value, while x and y must be zero in order for the vector to be perpendicular to both of the given vectors. Therefore, a basis for the subspace of all vectors perpendicular to both [1] [0] [0] [1] [-8] [-5] and [_] [3] [-2] [_] is:[0] [0] [1]

Explanation:

The five number summary is

in that exact order.

A five number summary of 1,2,8,20,21 means:

The IQR (interquartile range) is the distance from Q1 to Q3

IQR = Q3-Q1

IQR = 20-2

IQR = 18

The lower fence (L) is then calculated like so

L = Q1 - 1.5*IQR

L = 2 - 1.5*18

L = -25

If any values are smaller than this lower fence of -25, then they are considered small outliers. But we know that min = 1 is the smallest value. This means we do not have small outliers.

Now onto the upper fence (U)

U = Q3 + 1.5*IQR

U = 20 + 1.5*18

U = 47

If any values are larger than 47, then they are considered large outliers. But we know that max = 21 is the largest value. This means we do not have large outliers.

In summary, all of the data values are between min = 1 and max = 21, which guarantees they are definitely in the interval between L = -25 and U = 47.

This is why there are  no outliers in this data set.
