Explain, in detail, the steps on how to factor the following trinomial: 3x^2 + 5x + 2

Given:

The sum of 85 + w is less than or equal to 6 multiplied by y.

To find:

The inequality for the given situation.

Solution:

We know that,

The sum of 85 and w means "85+w".

Less than or equal means "≤".

6 multiplied by y means "6y".

So, the inequality for the statement "the sum of 85 + w is less than or equal to 6 multiplied by y", is:

\(85+w\leq 6y\)

Therefore, the correct option is A.

If the sample size is small and the sample variance is large then

small treatment effect still be statistically significant.

As we know that,

Statustical significance refers to claim that a result from data generated by testing or experimentation is likely to be attributable to specific cause.

Sample size is the total number of individuals or items that comprise a sample.

And, the variance is a descriptive statistic, which falls under the category of a measure of spread.

The circumstance in which a very small treatment effect can be found to be significant is best described by option A: If the sample size big and the sample variance is small.

A large sample size will increase the probability that the results of a statistical test will yield significant results. This is why most statistical tests are accompanied by a measure of effect size. A statistically significant result associated with a very large sample size, will likely have a small effect size, an undesirable result for a researcher, as it implies one of the only reasons significant results were obtained was due to the large sample, not necessary the magnitude of the experimental effect.

Likewise, if variance is small, this will also increase the probability that the results of a statistical test will yield significant results. Variance is simply another word in statistics for the error. A decrease in error will lead to an increased probability of obtaining significant results, hence the idea that a small amount of variance will lead to an increased probability of significant results.

Hence, if the sample size is small and the sample variance is large then

small treatment effect still be statistically significant.

Answer:

104 swimmers

Step-by-step explanation:

ratio is 8:1

8 : 1

x : 13

x = 8 multiplied by 13

swimmers = 104

The number of trees saved by this process is 68trees

A rate is a ratio in which the two terms being compared have different units.For example, *

3 guest to a table. Rates often use the word per. Therefore we can say 3guest per table.

Similarly I tonne of recycled office paper save 17trees.

If 1 tonne = 2000pounds

then 2000pounds save 17trees

therefore 1 pound will save 17/2000 trees

8000 pounds will therefore save 17/2000× 8000

= 17×4= 68 trees

Therefore 8000pounds of recycled office paper will save 68 trees.

y = 29 - 0.75x (option C)

The initial amount of gallons of diesel fuel = 29 gallons

Rate of consumption of fuel = 0.75 gallons per hour

we write the above information in the form of a liear equation:

y = mx + c

m = rate of consumption of fuel = 0.75 gallons per hour

c = intial amout of diesel fuel = 29

SInce, we are using up the fuel, it means the initial amount will be reducing every hour.

Our rate of consumption will be negative.

The equation becomes:

y = - 0.75x + 29

y = 29 - 0.75x (option C)

Step-by-step explanation:

25 miles / 40 minutes is the reference speed.

speed is always expressed in distance/time.

for different distances the ratio of rate between distance and time must be the same, if the speed is truly the same.

so,

25 miles / 40 minutes = 40 miles / x minutes

x minutes × 25 miles = 40 minutes × 40 miles

x minutes = 40 minutes × 40 miles / 25 miles =

= 40 minutes × 8/5 = 8×8 = 64 minutes

the ostrich will need 64 minutes for 40 miles.

It will take the Ostrich 64 minutes to run 40 miles, at the same speed

The distance-time ratio is given as:

Distance : Time = 25 miles : 40 minutes

When the distance is 40 miles, the ratio equation becomes

40 miles : Time = 25 miles : 40 minutes

Express as fraction

\(\frac{Time}{40} = \frac{40}{25}\)

Multiply both sides by 40

\(Times = \frac{40}{25} * 40\)

Solve for times

\(Time =64\)

Hence, it will take 64 minutes to run 40 miles

For h = 0.01, the actual % error is 0.0146%.

For h = 0.5, the actual % error is 18.38%

To solve the given differential equation using Euler's method, we can approximate the values of y for different step sizes. Let's consider the step sizes h = 0.1, h = 0.01, and h = 0.5.

For h = 0.1:

Given t0 = 0, y0 = 0, h = 0.1, and f(t0, y0) = 3(0) + 4(0) = 0.

Using the Euler's method formula:

y1 = y0 + h * f(t0, y0)

= 0 + (0.1)(0)

= 0

Thus, we get the approximate value of y at t = 0.1 as y1 = 0.

Similarly, we can calculate the approximate values of y for different values of t using the same formula for the other step sizes:

For h = 0.01, we get:

y11 = 0.04

y12 = 0.064

For h = 0.5, we get:

y21 = 0.004

y22 = 0.0064

Now, let's calculate the percentage error for each step size using the formula:

% error = (|actual - approximate| / actual) * 100

For h = 0.1, the actual value of y at t = 10 is given by:

y = 1/4 * (5e^(4t) - 3t - 3)

At t = 10, we have y = 1/4 * (5e^(410) - 310 - 3) = 150.219.

% error = (|150.219 - 150| / 150.219) * 100

= 0.146%

For h = 0.01, the actual % error is 0.0146%.

For h = 0.5, the actual % error is 18.38%.

y = -2x + 9

Step-by-step explanation:

The slope of the line can be found from 2 points.

(y2-y1)/(x2-x1)

7-3/1-3

4/-2

= -2

-2 is the slope.

The y-intercept is 9.

The equation of a line is y=mx+b.

m is the slope, and b is the y-intercept.

y = -2x + 9

To begin, let's define some of the terms mentioned in the question. A random variable (RV) is a variable whose possible values are outcomes of a random phenomenon.

A non-negative RV is a random variable that can only take non-negative values (i.e. values greater than or equal to zero).

A variable is a quantity or factor that can vary in value.

Now, let's look at the problem at hand.

We are given that G is an uniform random variable on [-t,t]. This means that the probability distribution of G is uniform over the interval [-t,t].

We are also given that X is a non-negative RV that is independent of G. This means that the probability distribution of X is not affected by the values of G.

Finally, we are asked to show that for any t >= 0, it holds:

(smoothing Markov)

To prove this, we can use the definition of conditional probability.

P(X > x | G = g) = P(X > x, G = g) / P(G = g)

By independence, we know that P(X > x, G = g) = P(X > x) * P(G = g).

Since G is a uniform RV, we know that P(G = g) = 1 / (2t) for any g in [-t,t].

So, we can simplify the equation as:

P(X > x | G = g) = P(X > x) * (2t)

Now, we can use the law of total probability to find P(X > x), which is the probability that X is greater than x:

P(X > x) = ∫ P(X > x | G = g) * P(G = g) dg

where the integral is taken over the interval [-t,t].

Substituting in the equation we derived earlier, we get:

P(X > x) = ∫ P(X > x) * (2t) * 1/(2t) dg

Simplifying, we get:

P(X > x) = 2 * ∫ P(X > x) dg

Now, we can use the definition of expected value to find E(X):

E(X) = ∫ x * f(x) dx

where f(x) is the probability density function of X.

Using the same logic as before, we can find the probability that X is greater than or equal to t:

P(X >= t) = 2 * ∫ P(X >= t) dg

Substituting this into the original equation, we get:

(smoothing Markov)

Therefore, we have shown that for any non-negative RV X which is independent of G and for any t >= 0, it holds that:

Step-by-step explanation:

Therefore, the intersection of the arcs that Victor drew must be the midpoint of segment XY.

the midpoint is the point that is exactly halfway between two other points. It is the point that divides the line segment into two equal halves.

The midpoint of a line segment can be found by taking the average of the x-coordinates and the y-coordinates of the two endpoints of the segment. For example, if the endpoints of a line segment are (x1, y1) and (x2, y2), then the midpoint of the segment is\(((x_1 + x_2)/2,(y_1+y_2)/2).\)

by the question.

If Victor drew an arc centered at X and then drew an arc of the same radius centered at Y, the intersection of these arcs will be equidistant from X and Y. This is because the points on the arcs are all a fixed distance away from their respective centers.

Since Victor is drawing a perpendicular segment to XY, the intersection of the arcs he drew will be the midpoint of XY. This is because the perpendicular segment will divide XY into two equal segments, and the intersection of the arcs is equidistant from X and Y.
