Answer:

Step-by-step explanation:

You want points A(-4, 0), B(0, -1) and C(-3, -3) reflected across the y-axis and translated left 5 and up 2.

The reflection across the y-axis changes the sign of the x-coordinate:

  (x, y) ⇒ (-x, y)

The translation adds the translation vector to the reflected coordinates.

  (x, y) ⇒ (x -5, y +2) . . . . . . translation (by itself)

Then the result of both transformations is ...

  (x, y) ⇒ (-x -5, y +2)

Answer:

\(0 \leq p < 6\)

Step-by-step explanation:

Given

\(t = 6.95p + 29.95\)

\(Amount = 70\)

Required

Determine the domain

First, we need to solve for p

Substitute 70 for t in \(t = 6.95p + 29.95\)

\(70 = 6.95p + 29.95\)

Collect Like Terms

\(6.95p = 70 - 29.95\)

\(6.95p = 40.05\)

Solve for p

\(p = 40.05/6.95\)

\(p = 5.76\)

This implies that Larry can not invite up to 6 people.

Hence, the domain can be represented as: \(0 \leq p < 6\)

In the proportion (5x + 1):3 = (2x + 2):7, the value of x is -1/29.

In the proportion (6x):(4x) = 7, there is no value of x that satisfies the proportion.

To find the value of x in the given proportions, let's solve them one by one:

(5x + 1) : 3 = (2x + 2) : 7

To solve this proportion, we can cross-multiply:

7(5x + 1) = 3(2x + 2)

35x + 7 = 6x + 6

Subtracting 6x from both sides and subtracting 7 from both sides:

35x - 6x = 6 - 7

29x = -1

Dividing both sides by 29:

x = -1/29

Therefore, the value of x in the first proportion is -1/29.

(6x) : (4x) = 7

To solve this proportion, we can simplify the left side:

6x / 4x = 7

Dividing both sides by 2x:

3/2 = 7

This equation is not true, as 3/2 is not equal to 7.

Therefore, there is no value of x that satisfies the second proportion.

In summary, the value of x in the proportion (5x + 1) : 3 = (2x + 2) : 7 is -1/29, and there is no value of x that satisfies the proportion (6x) : (4x) = 7.

It has been a good while since I have done this type of work so I am deeply sorry if I am wrong.

The experimental probability of rolling an odd number is around  683.3333%, which is 58.3333% more than the theoretical probability.

Again I am deeply sorry if I am wrong, have a good rest of your day!

The experimental probability of rolling an odd number is 60%, which is 10% more than the theoretical probability.

The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

A special 8-sided die is marked with the numbers 1 to 8.

It is rolled 20 times with these outcomes:

{3 4 5 2 7 1 3 7 2 6 2 1 7 3 6 1 8 3 5 6}

The experimental probability of rolling an odd number is :

⇒ 12/20

⇒ 0.6

The percentage of experimental probability = 0.6 × 100 = 60%

Theoretical probability as:

⇒ 4/8 × 100 = 50%

Difference between experimental and theoretical probability

⇒ 60 - 50 = 10%

Hence, the experimental probability of rolling an odd number is 60%, which is 10% more than the theoretical probability.

We substitute -1+1/6y for x in the second equation (bottom equation) in order to solve the system by the substitution method.

The given system of equations are 2x-1/3y = -2...(1)

3x+y=1...(2)

We solve this system of equations by using substitution method.

Let us solve for x in equation to substitute it in equation (2).

2x=-2+1/3y

Divide both sides of equation by 2.

x=-1+1/6y

Check the picture below.

so the parabolic path of the object is more or less like the one shown below in the picture, now this object has an initial of 1240 ft, as it gets thrown from the ski lift, so from 0 seconds is already higher than 1000 feet.

\(h=-16t^2+32t+1240\hspace{5em}\stackrel{\textit{a height of 1000 ft}}{1000=-16t^2+32t+1240} \\\\\\ 0=-16t^2+32t+240\implies 16t^2-32t-240=0\implies 16(t^2-2t-15)=0 \\\\\\ t^2-2t-15=0\implies (t-5)(t+3)=0\implies t= \begin{cases} ~~ 5 ~~ \textit{\LARGE \checkmark}\\ -3 ~~ \bigotimes \end{cases}\)

now, since the seconds can't be negative, thus the negative valid answer in this case is not applicable, so we can't use it.

Answer: 12 Minuets

Step-by-step explanation:

(a) The closed form for ∑2 is 2.

(b) The closed form expression for ∑3 is 24.

(c) The closed form for the sum ∑n = 0(― 1)² ― 1 is n(1 - n) / 2.

(d) The value of -3 matches the manual computation of the four terms.

Our closed form solution is correct.

To find the closed form for ∑2, we can use the formula for the sum of the first n terms of an arithmetic series:

∑2 = n(a + l) / 2

In this case, a = 2 (the first term) and l = 2 (the last term) since we are summing a series of 2's.

We also know that there is only one term, so n = 1.

Substituting these values into the formula, we have:

∑2 = 1(2 + 2) / 2

= 4 / 2

= 2

The formula for the sum of the first n terms of an arithmetic series is:

∑n = n(a + l) / 2

In this case, we have a = 3 (the first term), l = 13 (the last term), and n = 3 (the number of terms).

Substituting these values into the formula, we get:

∑3 = 3(3 + 13) / 2

= 3(16) / 2

= 48 / 2

= 24

The formula we developed in class is:

∑n = n(a + a + (n - 1)d) / 2

In this case, we have a = 0 (the first term) and d = -1 (the common difference).

Substituting these values into the formula, we get:

∑n = n(0 + 0 + (n - 1)(-1)) / 2

= n(0 - n + 1) / 2

= n(1 - n) / 2

To test the closed form solution for ∑3 = 0(― 1)² ― 1, we substitute n = 3 into the closed form expression we derived in part (c):

∑3 = 3(1 - 3) / 2

= 3(-2) / 2

= -6 / 2

= -3

Now, let's manually compute the sum of the first four terms of ∑3 = 0(― 1)² ― 1:

0(― 1)² ― 1 + 1(― 1)² ― 1 + 2(― 1)² ― 1 + 3(― 1)² ― 1

= 0 - 1 - 2 - 3

= -6

Answer:    \(-\frac{240}{289}\)

=========================================================

Explanation:

Use the pythagorean trig identity \(\sin^2(\theta)+\cos^2(\theta) = 1\) and plug in the fact that \(\cos(\theta) = \frac{8}{17}\\\\\)

Isolating sine leads to \(\sin(\theta) = -\frac{15}{17}\\\\\). I'm skipping the steps here, but let me know if you need to see them.

The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.

Therefore,

\(\sin(2\theta) = 2\sin(\theta)\cos(\theta)\\\\\sin(2\theta) = 2*\left(-\frac{15}{17}\right)*\left(\frac{8}{17}\right)\\\\\sin(2\theta) = -\frac{240}{289}\\\\\)

95% confidence interval is wider than 90% confidence interval.

Given as that unknown mean and a known variance.

let's suppose parameter for mean as µ and

for standard deviation σ.

we have sample of size n  as x1,x2,x3,x4.......xn.

Confidence means what degree of assurance do we desire that the interval estimate contains the  populace mean µ.

The likelihood that the interval falls within the level of confidence c

The population parameter is contained in estimate.

If the level of confidence is 90%, this means that we are 90%

confident that the interval contains the population mean, µ

The corresponding z-scores for 90% confidence interval are ± 1.645.

If the level of confidence is 95%, this means that we are 95%

confident that the interval contains the population mean, µ

The corresponding z-scores for 95% confidence interval are ± 1.96.

So In comparison to a 95% Confidence Interval, a 90% Confidence Interval would be narrower. This happens because the reliability of an interval containing the actual mean declines as the confidence interval's precision rises (i.e., CI width decreases) (less of a range to possibly cover the mean). Consider the case of 100% confidence; the interval must contain all possible values in order to guarantee that the mean is captured with 100% certainty.
