james sets off from home on a bike.The graph journey.
a)what is james' average speed on his outward journey

Answer:

D. [tex]\sqrt{3}[/tex] ; 2

Hope this helps!

Step-by-step explanation:

(a) The probability of having at least 10 defective chips is approximately 0.9131. (b) The probability of having between 15 and 20 defective chips is approximately 0.4135.

First, we need to find the mean (μ) and standard deviation (σ) for the binomial distribution.
μ = np = 500 * 0.03 = 15
σ = sqrt(np(1-p)) = sqrt(15*0.97) ≈ 3.66

(a) To find the probability of at least 10 defective chips, we'll calculate the Z-score and use a Z-table:

Z = (X - μ) / σ = (10 - 15) / 3.66 ≈ -1.36

P(X ≥ 10) = 1 - P(X ≤ 10) = 1 - 0.0869 = 0.9131

So, the probability of having at least 10 defective chips is approximately 0.9131

(b) To find the probability of between 15 and 20 defective chips (inclusive), we'll calculate the Z-scores and use a Z-table:

Z1 = (15 - 15) / 3.66 ≈ 0

Z2 = (20 - 15) / 3.66 ≈ 1.36

P(15 ≤ X ≤ 20) = P(Z1 ≤ Z ≤ Z2) = P(0 ≤ Z ≤ 1.36) = 0.4135

So, the probability of having between 15 and 20 defective chips is approximately 0.4135.

AB thus has a 12 unit length as the triangle ABE is a right triangle with hypotenuse AE and legs AB and 5 in length.

A closed triangle is a two-dimensional geometric shape having three straight edges and three angles. The shorter of a triangle's two sides is known as the hypotenuse, while its long sides are known as the triangle's legs. The longest side's opposing angle is referred to as the greatest or "opposite" angle in triangles. Angles are given names based on where they are in relation to the sides. An essential component of geometry is the study of triangles, and there are numerous varieties with distinctive characteristics. An equilateral triangle, on the other hand, has three equal edges and 3 equal angles that are each 60 degrees in length. A right triangle, for instance, has one angle that is 90 degrees in length.

Answer:

To solve this equation for the coefficient of the x term, we need to first simplify the equation by solving for x. 5x^2 + 3x - 2 = x/3 Multiplying both sides by 3 to eliminate the fraction, we get: 15x^2 + 9x - 6 = x Bringing all terms to one side: 15x^2 + 8x - 6 = 0 Now, we can use the quadratic formula to solve for x: x = [-b ± √(b^2 - 4ac)] / 2a where a = 15, b = 8, and c = -6 x = [-8 ± √(8^2 - 4(15)(-6))] / 2(15) x = [-8 ±

a. The time at which the population is at a maximum is 25 hours. b. The maximum population is 1,182,500.

A polynomial function of degree 2 is a quadratic function, while one of degree 1 is a linear function. The formula for a quadratic function is f(x) = ax² + bx + c, where a, b, and c are constants and an is not equal to 0. A parabola, a U-shaped curve, is the graph of a quadratic function. Depending on the sign of the leading coefficient, the function's minimum or maximum value is located at the parabola's vertex.

a) The highest value of the population function, which is a quadratic function with a negative leading coefficient, occurs near the parabola's vertex.

Thus, t = -b/2a.

Substituting the values  a = -1698, b = 85,000, and c = 10,000 we have:

t = -85000 / 2(-1698) = 25

Therefore, the time at which the population is at a maximum is 25 hours.

b) To determine the maximum population we substitute the value of t = 25.

p(25) = -1698(25)² + 85,000(25) + 10,000 = 1,182,500

Therefore, the maximum population is 1,182,500.

A nurse should empty a Hemovac wound suction device when it is half full to ensure proper functioning and prevent discomfort or injury to the patient due to the device becoming too heavy.

The rationale for a nurse to empty a Hemovac wound suction device when it is half full is to ensure the device is functioning correctly and to prevent it from becoming too heavy and potentially causing discomfort or injury to the patient.

When a Hemovac wound suction device is half full, it may start to lose suction, which can result in less efficient drainage of fluid from the wound site. By emptying the device, the nurse can ensure that the device is functioning correctly and that the suction pressure is maintained.

Additionally, allowing the device to become too full can make it heavy and uncomfortable for the patient, potentially causing discomfort or injury to the wound site. Therefore, emptying the device when it is half full can help prevent these complications and ensure that the patient remains comfortable throughout the healing process.

Tone's new monthly payment is 16.16% higher than his old monthly payment To solve the problem, we need to use the formula for the monthly payment of a mortgage loan:

monthly payment = (loan amount x monthly interest rate) / (1 - (1 + monthly interest rate)^(-n))

where:

loan amount = the amount of the loan

monthly interest rate = the annual interest rate divided by 12

n = the total number of payments (in months)

Let's first find the loan amount at the beginning of the mortgage. We know that Tone paid $9.99 per thousand, so we can set up a proportion:

$9.99 / 1000 = monthly payment / loan amount

Solving for the loan amount, we get:

loan amount = monthly payment / ($9.99 / 1000) = $1000 * (monthly payment / $9.99)

Substituting the given values, we get:

loan amount = $1000 * (monthly payment / $9.99) = $55,000

This means that Tone borrowed $55,000 at the beginning of the mortgage.

Now, let's find the old monthly payment. We know that Tone had a 10.5% adjustable rate mortgage for 30 years, which means he made 12 x 30 = 360 monthly payments. We can use the formula above to solve for the monthly payment:

monthly interest rate = 10.5% / 12 = 0.00875

n = 360

monthly payment = ($[tex]55,000 x 0.00875) / (1 - (1 + 0.00875)^(-360)[/tex]) = $512.47

Therefore, Tone's old monthly payment was $512.47.

Next, let's find the new monthly payment. We know that Tone will renew his mortgage at 12.5% interest rate, which means the new monthly interest rate is:

monthly interest rate = 12.5% / 12 = 0.01042

We also know that Tone will pay $10.68 per thousand, so we can set up a new proportion:

$10.68 / 1000 = new monthly payment / loan amount

Solving for the new monthly payment, we get:

new monthly payment = $10.68 / ($1000 / $55,000) = $595.40

Therefore, Tone's new monthly payment is $595.40.

Finally, let's find the percent increase in the new monthly payment compared to the old monthly payment. We can use the percent change formula:  

percent increase = ((new value - old value) / old value) x 100%

Substituting the given values, we get:

percent increase = (($595.40 - $512.47) / $512.47) x 100% = 16.16%

Therefore, Tone's new monthly payment is 16.16% higher than his old monthly payment

Based on the given data, there are a total of 13 packets and 5 of them are spicy. Therefore, the probability that the next packet Cooper pulls out of the box will be spicy is 5/13 or approximately 0.385 (rounded to three decimal places).

To calculate the probability of the next packet being spicy, we need to know how many packets of each flavor are in the box. Assuming that Cooper doesn't put back the packets he has pulled out, we can count the number of spicy packets and divide it by the total number of packets he pulled out.

In this case, out of the 13 packets he pulled out, 5 were spicy. Therefore, the probability of the next packet being spicy is 5/13, or approximately 0.38, or 38%. However, if the box is refilled with packets of different flavors, this probability may not hold.

The value of f(11) for the recursive rule and an explicit rule is 149.

An arithmetic sequence is a set of integers where each term is created by multiplying the preceding term by a fixed amount (referred to as the common difference). The nth term is often indicated by an, while the first term of the series is typically marked by a1. The following formula is used to determine the nth term in an arithmetic sequence:

a = a1 + (n-1)d

where d is the common distinction. In mathematics and other disciplines, arithmetic sequences are frequently employed to represent circumstances in which the pace or degree of change remains constant.

The recursive and explicit rule for the arithmetic sequence is given as:

an = a1 + (n-1)d

From the given graph f(1) = 19 and common difference = 32 - 19 = 13

The recursive rule is:

f(n) = f(n-1) + 13

The explicit rule is:

f(n) = 19 + 13(n-1)

Now, f(11) is calculated as:

f(11) = 19 + 13(11-1) = 19 + 130 = 149

Hence, the value of f(11) for the recursive rule and an explicit rule is 149.

What is exponential ?

Exponential refers to a mathematical function where the variable is in the exponent. Exponential functions have the general form:

[tex]f(x) = a^{x}[/tex]

here "a" is a constant called the base, and "x" is the variable. When the base "a" is a positive number greater than 1, the function grows exponentially as "x" increases. When the base "a" is a number between 0 and 1, the function decays exponentially as "x" increases.

We can start by using the formula for exponential decay:

[tex]N(t) = N0 * (1 - r)^{t}[/tex]

where N(t) is the population after t years, N0 is the initial population, r is the annual rate of decay (as a decimal), and t is the time in years.

We are given that the initial population is 670, so N0 = 670. After 4 years, the population has reduced to 557, so N(4) = 557. We can plug these values into the formula and solve for r:

[tex]557 = 670 * (1 - r)^{4}[/tex]

[tex](557/670)^{1/4} = 1 - r[/tex]

[tex]0.947 = 1 - r[/tex]

Since the rectangle is made up of 2 congruent trapezoids, we can find the length and width of the rectangle by combining the lengths and widths of the trapezoids.

First, let's find the length of the rectangle:

The length of each trapezoid is the average of its bases:

length = (11 + 8) / 2 = 9.5

Since the trapezoids are congruent, the length of the rectangle is twice the length of a trapezoid:

length of rectangle = 2 * 9.5 = 19

Next, let's find the width of the rectangle:

The height of the trapezoids is the same as the height of the rectangle:

height = 6

The width of the rectangle is the same as the width of a trapezoid. To find the width of a trapezoid, we need to use the Pythagorean theorem, since the trapezoid has a height of 6 and bases of 11 and 8:

width = sqrt(6^2 + ((11-8)/2)^2) = sqrt(36 + 0.75) = sqrt(36.75)

So, the width of the rectangle is:

width = sqrt(36.75)

Finally, let's find the area of the rectangle:

area = length * width = 19 * sqrt(36.75) ≈ 87.83

Therefore, the length of the rectangle is 19 units, the width is approximately 6.07 units, and the area is approximately 87.83 square units.

The volume of the solid generated by the revolution is 33.5 cubic units.

It is given that, the diameter of the semi-circle is 4 and it is rotated to one full rotation around its diameter.

A solid generated when a semicircle is being rotated about its diameter is called a "SPHERE".

Therefore, the volume of the solid generated by the revolution is the volume of the sphere.

The formula for the volume of the sphere is given by,

Volume of sphere = (4/3)πr³

where r is the radius and π has the default value of 3.14

Here, the given diameter is 4.

To find the radius = diameter/2

radius = 4/2 = 2.

Now, to calculate the volume of the sphere substitute r=2 and π=3.14

volume of the sphere = (4/3)×3.14×2³

⇒ (4/3)×3.14×8

⇒ 100.48 / 3
