keeping in mind that complex roots never come all by their lonesome, their sister is always with them, namely the conjugate, so if we know that there's a complex root of -2i or namely 0 - 2i, its conjugate is also there too, namely 0 + 2i, or just 2i, so then

\(\begin{cases} x=3\implies &x-3=0\\ x=-2i\implies &x+2i=0\\ x=2i\implies &x-2i=0 \end{cases}\qquad \implies (x-3)(x+2i)(x-2i)=\stackrel{0}{y} \\\\[-0.35em] ~\dotfill\\\\ \underset{\textit{difference of squares}}{(x+2i)(x-2i)}\implies [(x)^2-(2i)^2] \\\\\\\ [x^2-(4i^2)]\implies [x^2-[4(-1)]] \implies x^2+4 \\\\[-0.35em] ~\dotfill\\\\ (x-3)(x^2+4)=y\implies x^3-3x^2+4x-12=y\)

The z-score for P(? ≤ z ≤ ?) = 0.60 is approximately 0.25.

The z-score for P(z ≥ ?) = 0.30 is approximately -0.52.

How to find the Z score

P(Z ≤ z) = 0.60

We can use a standard normal distribution table or a calculator to find that the z-score corresponding to a cumulative probability of 0.60 is approximately 0.25.

Therefore, the z-score for P(? ≤ z ≤ ?) = 0.60 is approximately 0.25.

For the second question:

We want to find the z-score such that the area under the standard normal distribution curve to the right of z is 0.30. In other words:

P(Z ≥ z) = 0.30

Using a standard normal distribution table or calculator, we can find that the z-score corresponding to a cumulative probability of 0.30 is approximately -0.52 (since we want the area to the right of z, we take the negative of the z-score).

Therefore, the z-score for P(z ≥ ?) = 0.30 is approximately -0.52.

Step-by-step explanation:

Using the principle of counting ,

Total 648 , three-digit positive numbers are there such that all three digits are different and the first digit is not zero.

Counting principle: If an event occurs m times and another event occurs n times, the total number of occurrences of the event is m × n.

Let the three-digit number be abc.

Since, 3-digit numbers cannot have a 0, in the hundreds place i.e., c place. The first left most digit (a) can be any number from 1 to 9. Hundreds place can be entered in 9 ways. The 10ᵗʰ digit (i.e., b ) can contain a zero, but can not use the digit on 100ᵗʰ place(i.e., a ).So, there is also 9 ways to enter 10ᵗʰ digit. Similarly, the ones place( i.e., c) can contain zero digits, but the 100ᵗʰ and 10ᵗʰ placed digits cannot. So, there are 8 ways to fill the ones place.

Then, according to counting principles, the total possible three digit number is 9×9×8 = 648

Answer:

Hey just search up an algebraic calculator I finished my homework with it lol

Step-by-step explanation:

The dimensions of the college basketball court with a perimeter of 96 meters are:

The dimensions of a rectangular perimeter, like a basketball court, are the two sides (length and width).

The perimeter of a rectangle measures the four sides, that is, the two long sides and two wide sides.

The perimeter is given by the perimeter equation, P = 2(a+b).

The perimeter of the basketball court = 96 meters

The perimeter = 2(Length + Width)

2(Length + Width) = 96 meters

Length = 14 meters more than the width

The total difference of the two lengths = 28 meters (14 x 2)

Width = 17 meters (96 - 28)/2

Length = 31 meters (17 + 14)

Check:

Perimeter = 2(Length + Width)

96 meters = 2(31 + 17)

96 = 62 + 34

96 = 96

Thus, the college basketball court with a perimeter of 96 meters has the following dimensions: 31 meters in length and 17 meters in width.

Data given to us is as follows:

Standard Deviation, S = 8.5

Sample mean, m = 212.79

Sample size, n = 42

Significance level, a = 0.05

(a)This is a one tailed hypothesis test, specifically, this is a right tailed hypothesis test, because here the population mean is checked to be greater than the value 210.

(b)The hypotheses are:

H0: =\mu 210

Ha: \mu > 210

Standard error is calculated as:

SE = S/(n^0.5) = 8.5/(42^0.5) = 1.31

Calculate the z-statistic:

z = (m-210)/SE = (212.79-210)/1.31 = 2.129

The corresponding p-value for this z-value is:

p = 0.016

Since p < a. we have to reject the null hypothesis.

So, the new mean is significantly greater, as hypothesised.

(c)In this case:

Standard error is calculated as:

SE = S/(n^0.5) = 8.5/(20^0.5) = 1.9

Calculate the z-statistic:

z = (m-210)/SE = (212.79-210)/1.9 = 1.468

The corresponding p-value for this z-value is:

p = 0.071

Since p > a. we can't reject the null hypothesis.

So, the new mean is not significantly greater, as hypothesised.

(d)As sample size increases, the standard error of the mean also increases, which decreases the chances of the data obtained as being significant.

(e)Data given to us is as follows:

Standard Deviation, S = 1

Sample mean, m = 58.03

Sample size, n = 58

Significance level, a = 0.01

The hypotheses are:

H0: \mu = 58

Ha: \mu \neq 58

Standard error is calculated as:

SE = S/(n^0.5) = 1/(58^0.5) = 0.131

Calculate the z-statistic:

z = (m-58)/SE = (58.03-58)/0.131 = 0.229

The corresponding p-value for this two tailed test using this z-value is:

p = 0.81

Since p > a. we can't reject the null hypothesis.

So, the observed mean is not significantly different from the expected mean of 58.

The nth Taylor polynomial for the function f(x) = 1/x^2, centered at c = 5, and with n = 4, is given by T4(x) = 0.04 - 0.008(x - 5) + 0.0016(x - 5)^2 - 0.00032(x - 5)^3 + 0.000064(x - 5)^4.

To find the nth Taylor polynomial for a function centered at c, we need to find the coefficients of the polynomial by taking the derivatives of the function at the point c.

In this case, we have the function f(x) = 1/x^2 and we want to find the 4th degree Taylor polynomial centered at c = 5.

The general formula for the nth degree Taylor polynomial is given by:

Tn(x) = f(c) + f'(c)(x - c) + (f''(c)/2!)(x - c)^2 + ... + (f^n(c)/n!)(x - c)^n

Let's calculate the derivatives of f(x) = 1/x^2:

f'(x) = -2/x^3

f''(x) = 6/x^4

f'''(x) = -24/x^5

f''''(x) = 120/x^6

Now, let's substitute the values into the general formula:

T4(x) = f(5) + f'(5)(x - 5) + (f''(5)/2!)(x - 5)^2 + (f'''(5)/3!)(x - 5)^3 + (f''''(5)/4!)(x - 5)^4

Plugging in the values, we get:

T4(x) = 1/5^2 + (-2/5^3)(x - 5) + (6/5^4)/2!(x - 5)^2 + (-24/5^5)/3!(x - 5)^3 + (120/5^6)/4!(x - 5)^4

Simplifying the expression, we obtain the final result:

T4(x) = 0.04 - 0.008(x - 5) + 0.0016(x - 5)^2 - 0.00032(x - 5)^3 + 0.000064(x - 5)^4

Answer

- A suitable two-dimensional figure that can be used to model this frame is a rectangle.

- Perimeter of the rectangular frame = 203.2 cm

- Area of the rectangular frame = 2476.6 cm²

Explanation

A suitable two-dimensional figure that can be used to model this frame is a rectangle because a rectangle is the figure that has four sides with a pair of two equal sides.

The perimeter of a rectangle is given as

Perimeter = 2 (L + W)

where

L = Length of the rectangle = 61 cm

W = Width of the rectangle = 40.6 cm

Perimeter = 2 (L + W)

= 2 (61 + 40.6)

= 2 (101.6)

= 203.2 cm

The area of a rectangle is given as

Area = L × W

L = Length of the rectangle = 61 cm

W = Width of the rectangle = 40.6 cm

Area = L × W

= 61 × 40.6

= 2476.6 cm²

. The force and acceleration according the problem is directed along a horizontal surface, and we can omit the vector sign in Newton's law. The force we know F=45NF=45N, thus we should deduce the acceleration. The problem does not specify the initial speed at which time began to count, so for the first time interval, we may write the kinematics equation in the form

H0 says that the population means are equal.

In the context of a hypothesis test for the difference of means between two independent populations (x1 and x2), the null hypothesis (H0) states the following about the relationship between the two population means:
H0 says that the population means are equal.
In other words, the null hypothesis assumes that there is no significant difference between the means of the two populations. The alternative hypothesis would then state that the population means are different. Remember that hypothesis testing is a process to determine whether there is enough evidence to reject the null hypothesis in favor of the alternative hypothesis.
