Anthony has been training for the helpful pups charity race. the first week he trained, he ran 4 days and took the same two routes each day. he ran 1.5 miles around his neighborhood before school and a longer route at the park after school. by the end of the week, anthony had run a total of 28 miles. how many miles did anthony run each day after school?

If three pencils, each measuring one foot in length, are laid end to end touching, the total distance covered by the row would be 3 feet.

Since each pencil is 1 foot long, when three pencils are laid end to end, they form a row that is 3 feet long. The key information here is that the pencils are touching, which means there are no gaps between them. Therefore, the row would extend for a total distance of 3 feet.

In this scenario, the correct answer is option a, 3 ft. The row would not extend beyond 3 feet because there are only three pencils, each measuring one foot in length. If there were more pencils or if they were not touching end to end, the total distance covered by the row would be different. However, based on the given information, the row formed by the three one-foot-long pencils would have a length of 3 feet.

Answer:

5)m=11/10

6)m=-17/2

7)m=18.13

8)m=-26/9

BTW The M is an EXAMPLE

Step-by-step explanation:

the 90% confidence interval for p - um is (-0.816, 2.916), which can be rounded to (-0.82, 2.92). The closest option to this interval is (c) (-5.084, 7.284).

The point estimate for the difference in mean annual return is:

a - m = 7.3 - 6.2 = 1.1

To find the margin of error for a 90% confidence interval, we use the t-distribution with 16 degrees of freedom (conservative df) and a 5% significance level (90% confidence level):

t* = 1.745

The margin of error is then:

ME = t* * sqrt[(s1^2/n1) + (s2^2/n2)]

= 1.745 * sqrt[(0.093^2/17) + (0.124^2/17)]

= 0.916

The 90% confidence interval is:

(a - m) ± ME

1.1 ± 0.916

Thus, the 90% confidence interval for p - um is (-0.816, 2.916), which can be rounded to (-0.82, 2.92). The closest option to this interval is (c) (-5.084, 7.284).

Given:

The given statement is "A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle."

To find:

Whether the given statement in true or false.

Solution:

Area of circle is

\(A=\pi r^2\)

Where, r is the radius of the circle.

Let \(r_1\) be the radius of the original circle. So, the area of the circle is

\(A_1=\pi (r_1)^2\)

The circle is dilated by a scale factor of 1.5 to create a new circle. So, the radius of the new circle is:

\(r_2=1.5r_1\)

The area of the new circle is

\(A_2=\pi (r_2)^2\)

\(A_2=\pi (1.5r_1)^2\)

\(A_2=2.25\pi (r_1)^2\)

\(A_2=2.25A_1\)

The area of the new circle is 2.25 times the area of the original circle.

Therefore, the given statement is false.

Sam Soon's weight will become less than 58 kg after 37.33 days. If she continued on the diet, her weight would continue to reduce, but at a decreasing rate.

a) Assuming that Samsoon's weight is y(t) after t days starting the diet, then the differential equation that satisfies y(t) can be given by; The weight lost per day (d y(t) / d t) is proportional to the current weight (y(t)).

That is, the rate of weight loss is proportional to the weight of the person at the time. Mathematically, it can be expressed as;d y(t) / d t = - k * y(t), where k is the constant of proportionality.

To find the value of k, the following information is used; Samsoon has a basal metabolic rate of 1200 kcal and consumes 15 kcal of energy per 1 kg per day. It is said that 1 kg of fat is converted into 9000 kcal of energy.If Samsoon consumes 1800 kcal daily, then the difference between the amount of energy she consumes and the amount of energy her body requires to maintain her basal metabolic rate is;1800 - 1200 = 600 kcal.

Using the fact that 1 kg of fat is converted into 9000 kcal of energy, the amount of fat that Samsoon burns daily can be expressed as;f = 600 / 9000 = 0.0667 kg/day The weight lost per day (d y(t) / d t) can be expressed as the product of the rate of fat burn per day (f) and the weight of Samsoon (y(t)). That is;d y(t) / d t = - f * y(t) = - 0.0667 * y(t)

Thus, the differential equation that satisfies y(t) can be expressed as;d y(t) / d t = - 0.0667 * y(t)The solution of the differential equation is;y(t) = y(0) * e^(-0.0667 * t)b) To find the number of days later that Sam Soon's weight becomes less than 58 kg, the equation above is set to 58 kg. That is;58 = 64 * e^(-0.0667 * t)ln(58/64) = -0.0667tln(58/64) / -0.0667 = t= 37.33 days

(a)Samsoon's weight is denoted by y(t) after t days starting the diet.The differential equation that satisfies y(t) can be calculated by using the given information;Basal metabolic rate = 1200 kcal

Consumes 15 kcal of energy per 1 kg per day

Thus,Total calories consumed by Samsoon per day = Basal metabolic rate + Calories consumed per kg per day * Weight

= 1200 kcal + 15 kcal/kg/day * 64 kg

= 1200 + 960

= 2160 kcal/day

The amount of energy converted by 1 kg of fat = 9000 kcal/day

Thus, the total weight loss per day can be calculated as follows:difference in calories per day / calories converted by 1 kg fat

= (2160 - 1800) / 9000

= 0.004 kg per day

Thus, the differential equation that satisfies y(t) is dy/dt = -0.004 y

The solution can be obtained by using the method of separation of variables;dy/dt = -0.004

ydy/y = -0.004 dt

Integrating both sides, we get;

ln|y| = -0.004 t + C

Where C is a constant obtained by applying the initial condition y(0) = 64 kg.Using this initial condition;

ln|y| = -0.004 t + ln|64|ln|y|

= ln|64| - 0.004 t|y|

= 64 e^(-0.004 t)(b)

Sam Soon' s weight will become less than 58 kg when;64 e^(-0.004 t) < 58e^(-0.004 t) < 58 / 64e^(-0.004 t) < 0.90625t > (ln 0.90625) / (-0.004)t > 67.02

Thus, it will take more than 67 days for Sam Soon's weight to become less than 58 kg.If Sam Soon continues on the diet, her weight will continue to decrease as per the differential equation obtained in part (a) and will never become less than 0 kg.

However, it is important to note that there is a limit to the amount of weight that a person can lose safely, and a drastic reduction in calorie intake can have adverse effects on health.

In order to calculate the time it will take for Andrew to settle the loan, we can use the formula for compound interest. So, it will take Andrew approximately 5.22 years to settle the loan.

The formula is given as A = P(1 + r/n)^(nt), Where: A = the final amount, P = the principal (initial amount borrowed), R = the annual interest rate, N = the number of times the interest is compounded in a year, T = the time in years.

We know that Andrew borrowed R200 000 from a bank at an annual interest rate of 5.25% compounded quarterly and that he will make repayments of R6 000 at the end of every 3 months.

Since the first repayment will be made 3 months from now, we can consider that the initial loan repayment is made at time t = 0. This means that we need to calculate the value of t when the total amount repaid is equal to the initial amount borrowed.

Using the formula for compound interest: A = P(1 + r/n)^(nt), We can calculate the quarterly interest rate:r = (5.25/100)/4 = 0.013125We also know that the quarterly repayment amount is R6 000, so the amount borrowed minus the first repayment is the present value of the loan: P = R200 000 - R6 000 = R194 000

We can now substitute these values into the formula and solve for t: R194 000(1 + 0.013125/4)^(4t) = R200 000(1 + 0.013125/4)^(4t-1) + R6 000(1 + 0.013125/4)^(4t-2) + R6 000(1 + 0.013125/4)^(4t-3) + R6 000(1 + 0.013125/4)^(4t)

Rearranging the terms gives us: R194 000(1 + 0.013125/4)^(4t) - R6 000(1 + 0.013125/4)^(4t-1) - R6 000(1 + 0.013125/4)^(4t-2) - R6 000(1 + 0.013125/4)^(4t-3) - R200 000(1 + 0.013125/4)^(4t) = 0

Using trial and error, we can solve this equation to find that t = 5.22 years (rounded to 2 decimal places). Therefore, it will take Andrew approximately 5.22 years to settle the loan.

For tail probability the value of z that should be used to calculate a confidence interval with a 98% confidence level is Option C: 2.326.

What is probability?

Probability is a fundamental concept in statistics and mathematics that helps to measure the likelihood or chance of an event occurring. It provides a way to quantify uncertain events or situations and make informed decisions based on that information. The probability of an event can range from 0 to 1, with 0 indicating impossibility and 1 representing certainty.

To calculate the z-value for a 98% confidence level, we need to find the area in the standard normal distribution table that corresponds to a tail probability of (1-0.98)/2 = 0.01 on each side.

Looking at the standard normal distribution table, the z-value for a tail probability of 0.01 is 2.326.

Therefore, the value of z that should be used to calculate a confidence interval with a 98% confidence level is 2.326.

To determine the number of hex digits required to represent decimal numbers up to 1,999, we need to find the largest decimal number within that range and convert it to hexadecimal representation.

The largest decimal number within the range is 1,999. To convert it to hexadecimal, we divide it by 16 repeatedly until the quotient is 0, and then concatenate the remainders in reverse order.

1,999 divided by 16 gives a quotient of 124 and a remainder of 15 (F in hexadecimal representation).

124 divided by 16 gives a quotient of 7 and a remainder of 12 (C in hexadecimal representation).

7 divided by 16 gives a quotient of 0 and a remainder of 7 (7 in hexadecimal representation).

Thus, 1,999 in hexadecimal representation is 7CF. It requires three hex digits (7, C, F) to represent 1,999.

To calculate the number of bits required, we need to know the number of bits in one hex digit. Since each hex digit represents 4 bits, three hex digits would represent 3 * 4 = 12 bits.

Therefore, to represent decimal numbers up to 1,999, three hex digits are required, and it would take 12 bits.

The recursive formula for Lindsey's scores is aₙ = aₙ₋₁ \(\times\) r, and the explicit formula is aₙ \(= 67 \times r^{(n-1).\)

To find the recursive and explicit formulas for the given geometric sequence, let's analyze the pattern of Lindsey's scores.

From the given information, we can observe that Lindsey's scores are increasing at the same rate.

This suggests that the scores form a geometric sequence, where each term is obtained by multiplying the previous term by a common ratio.

Let's denote the first term as a₁ = 67 and the common ratio as r.

Recursive Formula:

In a geometric sequence, the recursive formula is used to find each term based on the previous term. In this case, we can write the recursive formula as:

aₙ = aₙ₋₁ \(\times\) r

For Lindsey's scores, the recursive formula would be:

aₙ = aₙ₋₁ \(\times\) r

Explicit Formula:

The explicit formula is used to directly calculate any term of a geometric sequence without the need to calculate the previous terms.

The explicit formula for a geometric sequence is:

aₙ = a₁ \(\times r^{(n-1)\)

For Lindsey's scores, the explicit formula would be:

aₙ \(= 67 \times r^{(n-1)\)

In both formulas, 'aₙ' represents the nth term of the sequence, 'aₙ₋₁' represents the previous term, 'a₁' represents the first term, 'r' represents the common ratio, and 'n' represents the term number.
