Answer:

25 cents

Step-by-step explanation:

1.) Set up an equation you can solve from the wording of the question:

(2/3)*m = 50, where "m" represents the money in your pocket.

2.) Solve for that equation:

m = 50*(3/2) = 150/2 = 75, so now you know the money you have in your pocket is 75 cents

3.) Multiply the money you have in your pocket by 1/3 to find 1/3 of the money you have in your pocket:

75*(1/3) = 25

Answer:

$20.4

Step-by-step explanation:

20% of 17= 3.4

Add it to the initial $17 and you get $20.4

Answer: $20.40

Step-by-step explanation:

Since you're giving a 20% tip, your total will be 120% the price of the shampoo and cut.

17 * 120%

= 17 * 1.2

= 20.4

The total amount of money you spent at the salon and barbershop is $20.40

The trigonometric form of the complex number z = -1 - i is z = √2cis(3π/4) and the roots of √z are √2/2cis(3π/8) and √2/2cis(11π/8).

a) Trigonometric form of the complex number z = -1 - i is given by:

r = |z| = √(1²+1²) = √2θ = arctan(-1/-1) + π = 3π/4

Therefore, z = √2cis(3π/4)b)

Since, √z = (√2cis(3π/4))/2

= (√2/2)(cis(3π/4)/2), the roots of √z are given by:

√2/2cis(3π/4 + 2nπ)/2, where n = 0, 1.

Therefore, the roots are √2/2cis(3π/8) and √2/2cis(11π/8) and they are plotted as shown below:

 In summary, the trigonometric form of the complex number z = -1 - i is z = √2cis(3π/4) and the roots of √z are √2/2cis(3π/8) and √2/2cis(11π/8).

The term that describes variables that represent the characteristics or attributes of participants and cannot be manipulated is called "non-manipulated variables" or "non-experimental variables".

These variables are typically measured or observed as they naturally exist and are not intentionally changed or controlled by the researcher. Non-manipulated variables are often used in observational studies or correlational research designs where the focus is on examining relationships or associations between variables rather than establishing cause-and-effect relationships through experimental manipulation.

There are 85,860 ways the runners can finish first, second, and third in the race.

The number of ways the runners can finish first, second, and third can be calculated using the concept of permutations.

For the first position, there are 45 runners who can finish first.

For the second position, there are 44 runners left who can finish second (since one runner has already finished first).

For the third position, there are 43 runners remaining who can finish third (since two runners have already finished).

The total number of ways the runners can finish first, second, and third is given by the product of these individual possibilities:

Number of ways = 45 * 44 * 43 = 85,860

Therefore, there are 85,860 ways the runners can finish first, second, and third in the race.

Answer:

Step-by-step explanation:

The formula to approach this shall be:

( Final price - Initial price )/ Final price × 100/1 ............. 1

Hence for the snow shovels

Initial price = $241.50 for 7

Each will cost = $241.50/7

= $34.5

Final price for snow shovels

= $105.57 for 3 shovels

Each will cost = $105.57/3

= $35.19

Now considering the bags of salt

Initial price = $6.20 each

Final price = $39.06 for 6 bags

Each bag cost = $39.06/6

= $6.51

Now apply the formula in equation (1)

For snow shovels

($35.19- $34.5)/$34.5 × 100/1

= 0.69/34.5 × 100/1

= 0.02×100/1

= 2%

For bags of salt

($6.51-$6.20)/$6.20 ×100/1

0.31/6.20×100/1

0.05×100/1

= 5%

Hence from the above solution, we can now deduce that shovel increased by 2% while bags of salt went up by 5%.

Using Simpson's Rule, the cardiac output can be estimated by approximating the area under the curve formed by the dye concentration readings at two-second intervals.

Simpson's Rule is a numerical method used to approximate definite integrals by dividing the interval into subinterval and applying a weighted average of function values. In this case, we have the time (t) and dye concentration (c(t)) readings at two-second intervals.

To estimate the cardiac output, we need to find the integral of the concentration function over the given time interval. Simpson's Rule can be applied by dividing the interval into subintervals (in this case, 0-12 seconds) and using the given function values to calculate the approximate integral.

By applying Simpson's Rule to the given data, the cardiac output can be estimated by calculating the weighted average of the function values and multiplying it by the width of the subintervals.

Please note that since the table is incomplete, providing the exact calculation and result of the cardiac output is not possible without additional data.

After considering all the given data we conclude that approximate percentage of area under the curve is 10.6%, which is approximately 0.106 as a decimal or 53/500 as a fraction

In  case of standard normal distribution, the area under the curve less than 1.25 is 0.894.
Then the standard normal distribution is symmetric about the mean, the area under the curve less than -1.25 is the same as the area under the curve greater than 1.25.
Hence, the approximate percentage of the area under the curve less than -1.25 is approximately
(1 - 0.894) * 100% = 10.6%,
which is approximately 0.106 as a decimal or 53/500 as a fraction

Answer:

Log Linear Model : log y = a + bx. Slope 'b' represent % change in ice cream sale, due to unit change in temperature.

Step-by-step explanation:

Assuming a log linear regression model, with dependent variable 'y' ie Ice cream sale & independent variable 'x' ie temperature sale.

In form of regression, log y = a + bx  {a = intercept}. Here, slope b represents response of one unit change (Increase) in temperature leading to b% change (ie rise) in ice cream consumption. Slope coefficient 'b' is likely to be positive, as temperature & ice cream sale are likely to be directly related, higher temperature (hot weather) imply high ice cream sale, & vice versa less sales for lower temperature (cool weather)

Answer:

v = 9x9x0.5x5 = 202.5 ft^3

Step-by-step explanation:

1. Observations: The boxplot graph reveals the distributions of corn yield for the 'Regular seed' and 'Kiln-dried seed.'

Both distributions appear approximately symmetric without any clear skewness. The center of the 'Kiln-dried seed' distribution seems to be slightly higher than the center of the 'Regular seed' distribution.

2. 95% Confidence Interval: Using Minitab, the 95% confidence interval for μ1-μ2 is (-28.88, -9.66) pounds per acre.

3. P-value and Conclusion: The corresponding two-sided test yields a p-value of 0.003.

Suggesting strong evidence of a difference in means between the two seed types. We can conclude that there is a significant difference in corn yield based on seed type.

4. Dotplots: By comparing the dotplots of 'Regular_seed,' 'Kiln_dried_seed,' and the 'Differences,'

It can be observed that the sample of differences has less variation compared to the two individual samples. The range of the differences is narrower, indicating reduced variation when focusing on the paired data.

5. Summary Statistics: The standard deviations for 'Regular_seed,' 'Kiln_dried_seed,' and the 'Differences' are 18.37, 14.71, and 8.21 pounds per acre, respectively.

Notably, the standard deviation of the differences is smaller compared to the standard deviations of the individual samples.

6. 95% Confidence Interval for μd: Using the paired t-test in Minitab, the 95% confidence interval for μd is (-18.16, -7.38) pounds per acre.

7. Comparison of Confidence Intervals: The confidence interval for μd (paired design) is narrower than the confidence interval for μ1-μ2 (unpaired design) from part 2.

This indicates that considering the pairing reduces the variability and provides a more precise estimate.

8. P-value and Conclusion for μd: The two-sided hypothesis test for μd yields a p-value of 0.001.

Indicating strong evidence of a significant difference in means between the two seed types.

9. Comparison of P-values: The p-value from the paired design (μd) is smaller than the p-value from the unpaired design (μ1-μ2).

This suggests that the paired design is more sensitive and able to detect smaller differences. The advantage of using a paired design becomes evident as it reduces unwanted variation, increases precision, and enhances the ability to detect significant differences.
