Last week      12          6             $186

Today           29        24            $554

Let the cost per pizza = x

Let the cost per cake = y

12x + 6y = 186 ... Equation 1

29x + 24y = 554 ... Equation 2

Multiply Equation 1 by 4:

48x + 24y = 744 ... Equation 3:

Subtract Equation 2 from Equation 3:

48x + 24y = 744

-

29x + 24y = 554

18x = 190

x = 10.56

= $10.56

Substitute x = $10.56 in Equation 1:

12x + 6y = 186

12(10.56) + 6y = 186

126.72 + 6y = 186

6y = 59.28

y = 9.88

= $9.88

Based on the information, it can be inferred that the correct fraction is 8/8 - 3/8 (option B).

To select the correct fraction we must perform the following procedure:

Analyze the fraction that we have as reference. Once we know its elements (numerator and denominator) we can identify any fracture that is related to it.

We analyze the options and identify the one that is related to the reference fraction. In this case the correct fraction would be 8/8 - 3/8 because we leave the same denominator and do the subtraction with the numerators.

So it would be 8 - 3 = 5. So the correct fraction is option B.

The ANOVA for each regression model shows that the overall F-test is significant, which means that at least one of the regression parameters is significant. This indicates that the regression model is useful for predicting the outcome.

The ANOVA for each regression model was conducted to determine whether the overall model is significant. To do this, an F-test was used to compare the sum of squares (SS) of the regression model versus the residual error (RSS). If the F-test is significant, then at least one of the regression parameters is significant and the model is useful for predicting the outcome. In both cases, the F-test was significant which indicates that the regression model is useful for predicting the outcome. The ANOVA also provides information about the individual parameters, such as the p-value associated with each parameter, which can be used to determine which parameters are significant. Overall, this indicates that the regression model is a useful tool for predicting the outcome and can be used to make informed decisions.

If the player wants to emphasize that his team generally scored a lot of points, it might be best to report the median.

The median and the mean are both measures of center in statistics. They help to describe where the center of the data set is located, but they are not the same thing.

The mean is calculated by adding up all the values in the data set and then dividing by the number of values. It gives a good overall picture of the average of the data set, but it is sensitive to outliers or extreme values.

On the other hand, the median is the middle value in a data set when the values are arranged in order.

To find the median, you must first arrange the values in order and then identify the middle value. If there are an even number of values, the median is the average of the two middle values.

The median is not as sensitive to outliers or extreme values as the mean, so it gives a more accurate picture of the center of the data set when there are outliers or extreme values.

The probability of drawing two orange balls, given that at least one ball is orange, is 1/5.

There are a total of 6 possible outcomes when selecting 2 balls from the urn without replacement: (O,O), (O,B), (B,O), (B,B), (O,B), (B,O).

The event that at least one of the balls selected is orange corresponds to the outcomes (O,O), (O,B), and (B,O). The probability of this event is the sum of the probabilities of the individual outcomes:

P(at least one orange) = P(O,O) + P(O,B) + P(B,O)

To calculate the individual probabilities, we can use the formula for the number of combinations of n items taken k at a time:

C(n,k) = n! / (k! (n-k)!).

The probability of each outcome is the number of ways it can occur divided by the total number of possible outcomes:

P(O,O) = C(2,2) / C(4,2)

= 2! / (2! (2!)) / (4! / (2! (2!)))

= 1/6

P(O,B) = C(2,1) * C(2,1) / C(4,2)

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

= 2/6

P(B,O) = P(O,B) = 2/6

So,

P(at least one orange) = 1/6 + 2/6 + 2/6

=> 5/6

And the probability that both balls are orange is:

P(both orange) = P(O,O) = 1/6.

So, the probability of drawing two orange balls, given that at least one ball is orange, is 1/5.

This indicates that the population variance is, with 99% confidence, between 8.53 and 9.35.

The chi-square distribution can be used to compute the population variance's 99% confidence interval estimate based on a sample standard deviation of 12 and a sample size of 10.

The confidence interval's formula is:

(s² / X²) * (n - 1) < σ² < (s² / X²) * n

Where X² is the upper percentile of the chi-square distribution with n-1 degrees of freedom, n is the sample size (10), and s² is the sample variance  (12² = 144).

Using a chi-square table with 9 degrees of freedom and a 99% level of confidence, we can determine that  X² = 16.919 As a result,

the population variance's confidence interval is:

(144 / 16.919) * (10 - 1) < σ² < (144 / 16.919) * 10

(8.53 < σ² < 9.35)

Bashir would need to invest $18,900, to the nearest hundred dollars, for the value of the account to reach $29,000 in 19 years.

Investment refers to the allocation of money or capital to an asset or a project with the expectation of generating a profit or earning an income. Investment can take many forms, including the purchase of stocks, bonds, real estate, or other financial products, as well as the financing of a business or a startup.

Investing involves risk, as the potential return on investment is not guaranteed. Investors must carefully evaluate the potential risks and returns of each investment opportunity before deciding where to allocate their capital.

Investment can be divided into two main categories: short-term and long-term. Short-term investments, such as savings accounts and money market funds, offer relatively low returns but also have lower risk. Long-term investments, such as stocks and real estate, have higher potential returns but also higher risk.

To find the amount that Bashir needs to invest to reach $29,000 in 19 years, we can use the formula for the future value of an investment:

Future Value = Principal * (1 + (Interest Rate ÷ Number of Compounding Periods))^(Number of Compounding Periods x Time in Years)

In this case, the interest rate is 5.7% compounded quarterly, so:

Interest Rate ÷ Number of Compounding Periods = 5.7 ÷ 4 = 1.425%

And the time in years is 19, so the number of compounding periods is 4 * 19 = 76.

Now, we can plug in the values into the formula:

Future Value = Principal * (1 + (1.425 ÷ 100))^(76)

Future Value = Principal * (1.01425)^76

Future Value = 29,000

Solving for Principal, we get:

Principal = 29,000 ÷ (1.01425)^76

Rounding to the nearest hundred dollars, we get:

Principal = $18,900

So, Bashir would need to invest $18,900, to the nearest hundred dollars, for the value of the account to reach $29,000 in 19 years.

You want the values of x that correspond to y-values of -2, 0, 4, 6, given the relation y = -2/3x +2.

One way to find the x-values is to read them from a graph of the equation. That is what we have done in the first attachment. This tells us the table is ...

  [tex]\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&-2\\3&0\\-3&4\\-6&6\\\cline{1-2}\end{array}[/tex]

You can solve the equation for x, then use that with the given y-values.

  y = -2/3x +2

  y -2 = -2/3x . . . . . subtract 2

  -3/2(y -2) = x . . . . . multiply by -3/2

Using the given y-values, we find the corresponding x-values to be ...

  -3/2({-2, 0, 4, 6} -2) = -3/2{-4, -2, 2, 4} = -3{-2, -1, 1, 2} = {6, 3, -3, -6}

These are the values that we obtained from the graph.

  For y = {-2, 0, 4, 6}, x = {6, 3, -3, -6}.

The car's value will exceed $10,000 during the interval of 6.97 years to  12.97 years.

To find the interval during which the car's value exceeds $10,000, we can use the following formula to calculate the value of the car after n years:

Value = $20,000 × [tex](1 - 0.15)^n[/tex]

We want to find the number of years, n, such that Value > $10,000. Rearranging the equation, we get:

n = (log(Value / $20,000)) / (log(1 - 0.15))

Substituting Value = $10,000, we find that n = approximately 6.97 years.

So, the car's value will exceed $10,000 from approximately 6.97 years after it was purchased until about 12.97 years after it was purchased.
