Based on the plot, the number of practice puzzles per week that members solve if they finish the contest puzzle

in one hour is c 4

The line of best fit for the scatter plot shows that there is a positive correlation between the number of practice puzzles solved per week and the time it takes to solve a contest puzzle. This means that as the number of practice puzzles solved per week increases, the time it takes to solve a contest puzzle decreases.

If a member finishes a contest puzzle in one hour, they are on the line of best fit. This means that they solve approximately 4 practice puzzles per week.

The other options are incorrect. Option a is too high, option b is too low, and option d is not on the line of best fit.

Answer for you second question:

Using an online finance calculator, the yield to maturity (YTM) of the Ashburn Company's bond at a coupon rate of 8.9 percent paying semiannual interest and selling at 113% of par value is 7.45%.

The Yield to maturity (YTM) is the total return, expressed as an annual rate, anticipated by a bondholder on a bond if it is held until its maturity date.

The maturity date refers to the date when the principal of a fixed investment is repaid at the maturity value.

The yield to maturity can also be computed using the following formula:

YTM = [(Face value/Bond price)1/Time period]-1.

Face (par) value = $100

Bond current price = $113 ($100 x 113%)

Annual coupon rate = 8.9%

Coupon frequency = Semi-annually

Years to maturity = 15 years

Result:

Yield to maturity (YTM) = 7.45%

A quadratic function can be represented as

y = a(x - h)^2 + k

Where

Vertex = (h, k)

In this case, the vertex is the minumum

So, we have

(h, k) = (0, 5)

So, we have

y = ax^2 + 5

Using the other points, we have

a(2)^2 + 5 = 9

So, we have

a = 1

So, the function is y = x^2 + 5

Answer:

The result is \(\frac{2}{3}\).

Step-by-step explanation:

Since there is no symbol in front of the first bracket, we can straight up remove it with no consequences.

Hence, the equation we get is:

\(\frac{3}{8} + \frac{2}{3} - \frac{3}{8}\)

\(= \frac{2}{3}\)

Therefore, the result is \(\frac{2}{3}\).

Answer:

We conclude that a compact microwave oven consumes a mean of more than 250 W.

Step-by-step explanation:

We are given that an appliance manufacturer claims to have developed a compact microwave oven that consumes a mean of no more than 250 W with a population standard deviation of 15 W.

They take a sample of 20 microwave ovens and find that they consume a mean of 257.3 W.

Let \(\mu\) = mean power consumption for microwave ovens.

So, Null Hypothesis, \(H_0\) : \(\mu\) \(\leq\) 250 W     {means that a compact microwave oven consumes a mean of no more than 250 W}

Alternate Hypothesis, \(H_A\) : \(\mu\) > 250 W     {means that a compact microwave oven consumes a mean of more than 250 W}

The test statistics that would be used here One-sample z test statistics as we know about the population standard deviation;

                                T.S. =  \(\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }\)  ~ N(0,1)

where, \(\bar X\) = sample mean power consumption for ovens = 257.3 W

            σ = population standard deviation = 15 W

            n = sample of microwave ovens = 20

So, the test statistics  =  \(\frac{257.3-250}{\frac{15}{\sqrt{20} } }\)

                                      =  2.176

The value of z test statistics is 2.176.

Now, at 0.05 significance level the z table gives critical value of 1.645 for right-tailed test.

Since our test statistic is more than the critical value of t as 2.176 > 1.645, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region due to which we reject our null hypothesis.

Therefore, we conclude that a compact microwave oven consumes a mean of more than 250 W.

Hi Rosie!

To find the y-intercept and slope of the line represented by the equation -8x + 9y = 36, we can convert the equation into slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

First, we can isolate the y term on one side of the equation:

9y = 36 + 8x

Dividing both sides by 9:

y = 4 + (8/9)x

So the slope of the line is m = 8/9 and the y-intercept is b = 4.

To verify, we can plug in x = 0 and y = 4 into the original equation:

-8 * 0 + 9 * 4 = 36, which is true.

Therefore, the y-intercept of the line is 4 and the slope is 8/9.

-34b4

Step-by-step explanation:

Since the variables are the same b4, you just add the constants (-16 & -18).

The z-score of a person who scored 330 on the exam is approximately 2.7.

To find the z-score of a person who scored 330 on the exam, we can use the formula for calculating the z-score:

z = (x - μ) / σ

where:

z is the z-score

x is the raw score (330 in this case)

μ is the mean (195 in this case)

σ is the standard deviation (50 in this case)

Substituting the values into the formula, we get:

z = (330 - 195) / 50

z = 135 / 50

z = 2.7

The z-score of a person who scored 330 on the exam is 2.7.

The z-score measures the number of standard deviations a particular data point is away from the mean.

In this case, a z-score of 2.7 indicates that the person's score of 330 is 2.7 standard deviations above the mean score of 195.

The z-score is useful for comparing data points across different normal distributions or for determining the relative position of a data point within a distribution.

A positive z-score indicates a value above the mean, while a negative z-score indicates a value below the mean.

In this context, a z-score of 2.7 suggests that the person's score is relatively high compared to the average performance on the exam.
