The mean temperature for the first 4 days in January was -6°C.
The mean temperature for the first 5 days in January was -5°C.
What was the temperature on the 5th day?

To answer the question, we need more information about the sample. Assuming that the sample consists of people who are interested in health and fitness, we can make some assumptions.

If a random person from the sample does not exercise, there is a higher probability that they do not follow a healthy diet as well. However, this is not a guarantee as there may be other reasons for not exercising such as health issues or lack of time. Without knowing the specifics of the sample, we cannot accurately determine the probability that the person does not diet. However, we can say that the likelihood of the person not following a healthy diet is higher if they do not exercise. In summary, the probability that a random person from the sample does not diet given that they do not exercise cannot be determined without further information about the sample.

Answer:

a negative slope

Step-by-step explanation:

In question 16, a 98% confidence interval was computed based on a sample of 41 Veterans' Day celebrations. If the confidence level were decreased to 90%, the margin of error would decrease, and the width of the confidence interval would also decrease.

This is because a lower confidence level requires a smaller range of values to be included in the interval, resulting in a narrower range of possible values. However, it's important to note that decreasing the confidence level also increases the risk of the interval not capturing the true population parameter.

1. Margin of Error: The margin of error is affected by the confidence level because it is directly related to the critical value (or Z-score) associated with the chosen confidence level. As the confidence level decreases, the critical value also decreases. This will result in a smaller margin of error.

2. Confidence Interval: The confidence interval is calculated by adding and subtracting the margin of error from the sample mean. Since the margin of error is smaller when the confidence level is decreased to 90%, the width of the confidence interval will also become narrower.

In summary, decreasing the confidence level from 98% to 90% will result in a smaller margin of error and a narrower confidence interval for the sample of 41 Veterans Day celebrations.

The exercise involves finding the product C = AB, where matrix A is given by [2 9] and matrix B is given by [3 6 1]. We need to perform the matrix multiplication to obtain the resulting matrix C.

Let's calculate the matrix product C = AB step by step:

Matrix A has dimensions 2x1, and matrix B has dimensions 1x3. To perform the multiplication, the number of columns in A must match the number of rows in B.

In this case, both matrices satisfy this condition, so the product C = AB is defined.

Calculating AB:

AB = [23 + 912 26 + 94 21 + 95]

[103 + 612 106 + 64 101 + 65]

Simplifying the calculations:

AB = [6 + 108 12 + 36 2 + 45]

[30 + 72 60 + 24 10 + 30]

AB = [114 48 47]

[102 84 40]

Therefore, the product C = AB is:

C = [114 48 47]

[102 84 40]

In summary, the matrix product C = AB, where A = [2 9] and B = [3 6 1], is given by:

C = [114 48 47]

The statement "the domain of an exponential function is all real numbers" is generally true. An exponential function is a mathematical function of the form f(x) = a^x, where a is a positive constant and x can be any real number.

Since x can be any real number, the domain of an exponential function is all real numbers. This means that you can input any real number into an exponential function and get a valid output.

However, there are some special cases where the domain of an exponential function is restricted. For example, if the base a of the exponential function is negative, the domain of the function is limited to even integer values of x, because negative numbers raised to non-integer powers are not defined in the real number system.

In addition, if the function has other operations or transformations applied to it, such as addition or multiplication, the domain of the function may be restricted by these operations.

Overall, while the domain of an exponential function is typically all real numbers, it's important to consider any special cases or restrictions that may apply to a specific function.

Answer:

Greatest prime factor of \(nt\) is 7.

Step-by-step explanation:

Given that

Two positive integers are \(n\) and \(t\).

(1) Greatest Common Factor or HCF of \(n\) and \(t\) is 5.

(2) Least Common Multiple or LCM of \(n\) and \(t\) is 105.

To find:

The greatest prime factor of the product \(nt\) = ?

Solution:

First of all, let us learn about a property of HCF and LCM of two numbers.

The product of two numbers \(p\) and \(q\) is equal to the product of their HCF and LCM.

\(p \times q =LCM\times HCF\)

Using this property for the given numbers:

\(n\times t =5\times 105\\OR\\nt =5\times105\)

Now, let us make prime factors of \(5 \times 105\) to find the greatest of the prime factors.

\(5\times 105 = 5\times 5 \times 21 =5\times 5 \times 3 \times \bold{7}\)

So, the prime factors of \(5 \times 105\) are 5, 5, 3 and 7.

Greatest prime factor of \(nt\) is 7.

Answer:

it is a statistical measure of the relationship between two variables that indicates the extent to which the variables change together in the same or opposite direction. Correlation does not imply causation, meaning that a correlation between two variables does not necessarily mean that one variable causes the other.

Based on this definition, the correct answer is b. Increasing values of X go with either increasing or decreasing values of Y. A correlation exists between two variables when both variables increase or decrease together. This statement captures the idea that correlation can be positive or negative, and that it reflects a linear relationship between two variables.

Step-by-step explanation:

a is wrong because it only describes positive correlation, not negative correlation.

c is wrong because it confuses correlation with consistency. Correlation does not require that higher values of X always go with higher or lower values of Y, only that they tend to do so on average.

d and f are wrong because they assume causation from correlation, which is a logical fallacy.

e is wrong because it contradicts itself. It says that increasing values of X go with increasing values of Y, which is positive correlation, but then it says that a correlation exists when both variables decrease together, which is negative correlation.

If X is correlated with Y, it implies a predictive statistical relationship between X and Y. This correlation can be positive or negative implying respective increase or decrease in values of both variables. But, this correlation doesn't prove causation.

If X is correlated with Y, it indicates a statistical relationship between the two variables, X and Y. This relationship can be positive or negative. If it is a positive correlation, as X increases, Y will also increase and similarly, as X decreases, Y will also decrease. Contrarily, in a negative correlation, as X increases, Y decreases and vice versa. However, it is important to understand that correlation does not imply causation. That is, if X and Y are correlated, it does not necessarily mean that changes in X cause changes in Y or vice versa. It only means that they move in a predictable manner relative to each other.

Step-by-step explanation:

The slope would be 4 (because in y=mx+b form, m = slope)

The y-intercept would be zero (0,0) since b = y-intercept, and there is no b in this equation.

From (0,0) you would rise four to get (0,4) and go over to the right one (1,4)

The area of a circle is equal to pi times the square of its Radius

Step-by-step explanation:

Answer:

Pie, Diameter, Circle

Step-by-step explanation:

According to the given information, the distance traveled by an object is directly proportional to the amount of time spent traveling. If an object travels for 6 hours and covers a distance of 933 miles, we can determine the distance it would cover in 9 hours and covers a distance of 1399.5 miles.

To solve this problem, we can set up a proportion based on the given information. Let's assume that "x" represents the distance traveled in 9 hours.

According to the problem, we know that the distance traveled is directly proportional to the amount of time spent traveling. Mathematically, this can be expressed as:

Distance / Time = Constant

Using the values provided, we can set up the proportion as follows:

933 miles / 6 hours = x miles / 9 hours

Now, we can cross-multiply and solve for "x":

(933 miles) * (9 hours) = (6 hours) * (x miles)

8397 miles = 6x

Dividing both sides of the equation by 6, we get:

x = 8397 miles / 6

x ≈ 1399.5 miles

Therefore, the object would travel approximately 1399.5 miles when traveling for 9 hours (rounded to the nearest hundredth).

The equation that we need to solve and the solution is:

A = 11.7mi/3 = 3.9 mi

We conclude that he needs to ride an average of 3.9 miles per day.

Here we know that Carter wants to ride his bicycle 28.7 miles this week, and he has already ridden 17 miles, so the distance left is:

D = 28.7 mi - 17mi = 11.7mi

Now, if he has 3 days to complete that distance, then the average distance that he needs to travel each day is given by the quotient:

A = 11.7mi/3 = 3.9 mi

So that is the equation that we need to solve and the solution, we conclude that he needs to ride an average of 3.9 miles per day.

Step-by-step explanation:

The products written in scientific notation are:

a) \(5.88*10^9\)

b) \(15*10^{12}\\\)

c) \(8.4*10^{-10}\)

d) \(42*10^{-7}\)

The first product we need to solve is:

\((4.2*10^6)*(1.4*10^3)\)

We can reorder that product into the one below:

\((4.2*1.4)*(10^6*10^3)\)

The exponents in the right side are added, so we get:

\((4.2*1.4)*(10^6*10^3) = 5.88*10^{3 + 6} = 5.88*10^9\)

Now let's do the same in the others.

b)

\((5*10^5)*(3*10^7)\\= 5*3*10^{5 + 7}\\= 15*10^{12}\\\)

Now we need to write the first number between 0 and 10, then we can rewrite this as:

\(1.5*10^{13}\)

c) Again doing the same thing.

\((4*10^{-3})*(2.1*10^{-7}})\\= 4*2.1*10^{-3 - 7}\\= 8.4*10^{-10}\)

d) Finally, this last product is:

\((6*10^{-2})*(7*10^{-5}})\\= 6*7*10^{-2 - 5}\\= 42*10^{-7}\)

Again we need to have a number between 0 and 10, so we can rewrite this as:
