The table has a greater rate of change.
The rates of change are equal.
In the given problem, we have a table showing the relationship between x and y values. By comparing the change in y with the change in x, we can determine the rate of change. Looking at the table, we observe that for every increase of 1 in x, there is a corresponding increase of 1 in y. Therefore, the rate of change for this table is 1.
The slopes are equal.
The equation has a greater slope.
In problem 2, we are given a linear equation in the form y = mx + b, where m represents the slope. The given equation is y = 2x + 7, which means the slope is 2. To compare the rates of change, we compare the slopes. If the slopes are equal, the rates of change are equal. In this case, the slopes are equal to 2, so the rates of change are the same.
The function rule has a greater slope.
The slopes are equal.
In problem 3, we are told that as x increases by 1, y increases by 3. This information gives us the rate of change between x and y. The slope of a function represents the rate of change, and in this case, the slope is 3. Comparing the slopes, we find that they are equal, as both have a value of 3. Therefore, the rates of change are the same.

The formula to compute a person's body mass index is B= 703x w/h2. B represents the body mass index, is the person's weight in pounds and represents the person's height in inches.
a. Solve the formula for w.
b. Find the weight to the nearest pound of a person who is 64 inches tall and has a body mass index of 21.45.
a. The formula B = 703w/h^2 can be solved for w by rearranging the equation as w = B * h^2 / 703.
b. For a person who is 64 inches tall and has a body mass index of 21.45, the weight can be calculated by substituting the values into the formula w = B * h^2 / 703, where B is 21.45 and h is 64 inches.
a. To solve the formula B = 703w/h^2 for w, we can rearrange the equation to isolate w on one side of the equation. Multiply both sides of the equation by h^2, then divide both sides by 703. The resulting equation is w = B * h^2 / 703.
b. To find the weight of a person who is 64 inches tall and has a body mass index of 21.45, we can substitute the values into the formula w = B * h^2 / 703.

HELP ME ASAP A die is rolled 8 times and you get 4, three times. What is the experimental probability of rolling a four?
Answer:
1/2 or 50%--------------------
The experimental probability is the ratio of actual outcomes and total outcomes:
P(Ex) = 4/8 = 1/2 or 50%Given P(x)=x^3 +2x^2 +4x+8. Write P in factored form (as a product of linear factors). Be sure to write the full equation, including P(x)=.
The factored form of the polynomial P(x) = x³ + 2x² + 4x + 8 is P(x) = (x + 1)(x² + x + 7). The quadratic factor x^2 + x + 7 cannot be further factored into linear factors with real coefficients.
To factor the polynomial P(x) = x³ + 2x² + 4x + 8, we can look for potential roots by applying synthetic division or by using synthetic substitution. In this case, we can start by trying small integer values as possible roots, such as ±1, ±2, ±4, and ±8, using the Rational Root Theorem.
By synthetic substitution, we find that -1 is a root of the polynomial. Dividing P(x) by (x + 1) using long division or synthetic division, we get:
P(x) = (x + 1)(x² + x + 7)
Now, we need to factor the quadratic expression x² + x + 7. However, upon factoring this quadratic expression, we find that it cannot be factored further into linear factors with real coefficients. Therefore, the factored form of P(x) is:
P(x) = (x + 1)(x² + x + 7)
Please note that the quadratic factor x² + x + 7 does not have any real roots. Therefore, the complete factored form of P(x) is as given above.

Taylor has 18 cents in dimes and nickels in her pocket. The number of dimes is four more than the number of nickels. How many of each coin does it have?
Answer:
Explained below.
Step-by-step explanation:
The value of different types of coins are as follows:
1 penny (p) = 1 cent
1 nickel (n) = 5 cents
1 dime (d) = 10 cents
1 quarter (q) = 25 cents
It is provided that Taylor has 18 cents in dimes and nickels in her pocket.
This is not possible.
Because the sum of any number of dime and nickel coins will always be a multiple of 5.
a·d + b·n = 10a + 5b = 5 (2a + b)
The value 18 cents can be formed as follows:
8p + d = 18 cents

The side length of an equilateral triangle is 7 centimeters. Find the length of the altitude
Answer:
Step-by-step explanation:
The altitude of an equilateral triangle is basically the height of the triangle. We can find this using trigonometry, even though I'm sure there's a beautiful little formula that can find this.
If you cut an equilateral triangle in half, you get two special 30-60-90 triangles. The base of each triangle is 3.5 cm in length, and the height (not the hypotenuse!) is equal to:
\(base*\sqrt{3}\)
So basically we have 3.5(sqrt(3)), or our altitude! Wow, how easy!
\(3.5(\sqrt{3})=6.06\)

if z is a standard normal variable, find the probability that z lies between −2.41 and 0. round to four decimal places.
The probability that z lies between -2.41 and 0 is approximately 0.9911.
What is the probability of z falling within a specific range?To find the probability that a standard normal variable, z, falls within a specific range, we can use the standard normal distribution table or a statistical calculator.
In this case, we want to find the probability that z lies between -2.41 and 0. By referencing the standard normal distribution table or using a calculator, we can determine the area under the curve corresponding to this range. The resulting value represents the probability of z falling within that range.
Approximately 0.9911 is the probability that z lies between -2.41 and 0 when rounded to four decimal places. This means that there is a high likelihood (approximately 99.11%) that a randomly chosen value of z from a standard normal distribution falls within this range.

Memoryless System: A system is memoryless if its output at any time depends on the input at that time only.Causal System:A system is causal if the output of the system at any time depends on only the present and past values of the input but not on the future values of the input.
Determine whether each of the given systems is memoryless and/or causal:a) h(t) = (t + 1)u(t − 1);Here, the system is not memoryless since the output depends on the past and current inputs. This is because of the presence of a unit step function, u(t-1) in the input signal. Since the system is a linear system, it is also causal.b) h(t) = 28(t + 1);This is a linear time-invariant system. It is both causal and memoryless as the output at any time t depends only on the value of the input signal at that time. The output is a scaled version of the input signal.c) h(t) = sinc(wct);Here, sinc(x) = sin(x) / x. This system is both causal and memoryless.
The output at any time t depends only on the input signal at that time and not on future input values.d) h(t) = e^(-4t)u(t − 1);This system is both causal and memoryless. Since the output at any time t depends only on the input signal at that time, and not on future input values.e) h(t) = e^1u(−t − 1);This system is causal but not memoryless. The presence of a unit step function, u(−t-1), in the input signal indicates that the output will depend on the past and present input values. The output at any time t depends on the present and past values of the input.f) h(t) = e^(-3|t|);This is a causal and memoryless system since the output at any time t depends only on the value of the input signal at that time.g) h(t) = 38(t);This is a linear system.

seeds are often treated with fungicides to protect them in poor-draining, wet environments. a small-scale trial, involving eight treated and eight untreated seeds, was conducted prior to a large-scale experiment to explore how much fungicide to apply. the seeds were planted in wet soil, and the number of emerging plants were counted. if the solution was not effective and seven plants actually sprouted, compute the following probabilities. (round your answers to four decimal places.) (a) what is the probability that all seven plants emerged from treated seeds? (b) what is the probability that six or fewer emerged from treated seeds? (c) what is the probability that at least one emerged from untreated seeds?
(a) The probability that all seven plants emerged from treated seeds is: P(7 treated) = 8C7 / 16C7 = 1 / 128, (b) The probability that six or fewer emerged from treated seeds is: P(6 or fewer treated) = 8C6 + 8C5 + 8C4 + 8C3 + 8C2 + 8C1 = 17 / 64.
(c) The probability that at least one emerged from untreated seeds is:
P(at least 1 untreated) = 1 - P(all treated) - P(6 or fewer treated) = 46 / 64
(a) There are 8C7 = 1 ways to choose 7 treated seeds out of 8. There are 16C7 = 128 ways to choose 7 seeds out of 16. So, the probability that 7 of the 7 plants that sprouted were treated is 1/128.
(b) There are 8C6 = 28 ways to choose 6 treated seeds out of 8. There are 8C5 = 56 ways to choose 5 treated seeds out of 8. There are 8C4 = 70 ways to choose 4 treated seeds out of 8. There are 8C3 = 56 ways to choose 3 treated seeds out of 8.
There are 8C2 = 28 ways to choose 2 treated seeds out of 8. There are 8C1 = 8 ways to choose 1 treated seeds out of 8. So, the probability that 6 or fewer of the 7 plants that sprouted were treated is 17/64.
(c) The probability that all 7 plants that sprouted were treated is 1/128. The probability that 6 or fewer of the 7 plants that sprouted were treated is 17/64. So, the probability that at least one of the 7 plants that sprouted was untreated is 1 - (1/128 + 17/64) = 46/64.
