Answer:

Polynomials are algebraic expressions that contain more than two terms. AN example would be: f(x) = x^3 + x^2 + x +1. This equation contains three terms, with the 3rd degree as its highest term. It also means that the graph passed three x-intercepts. This depends in the highest degree. So, the first thing you do is plot the intercepts because for sure, the graph will pass there.

Answer: The length of \(\overline{NP}\) is 10 units.

Step-by-step explanation:

We are given that,

Point O is on line segment \(\overline{NP}\) .

Then, \(\overline{NP}=\overline{NO}+\overline{OP}\)   (i)

Since we have given that OP=8 units and NO=2 units .

Now we will substitute these values in (i), we will get

\(\overline{NP}=8\ units+2\ units\\\\\Rightarrow\ \overline{NP}=10\ units\)

Hence, the length of \(\overline{NP}\) is 10 units.

The probability for a data point is less than is 0.8413.

The probability is the measure of the likelihood of an event to happen. It measures the certainty of the event.

The mean(μ)=4

Standard deviation(σ)=1

(P<5)

From the figure, standard normal distribution curve probability which we have to find P<5

It is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

P(x=4)=x-μ/σ

=4-4/1=0

P(x=4)=50%

P(x<5)=P(x=4)+P(x=1)

=50%+34.13%

=0.8413

P(x<5)=0.8413

Therefore, the probability a data point is less than 5 is 0.8413.

Answer:

He can choose by each players skill and depending on how long the game is he can sub them out throughout the game

Step-by-step explanation:

The total different possible ways can the coach choose a team of 5 if each person has an equal chance of being selected is, 8568 or C(18, 5)

A permutation can be defined as the number of ways a set can be arranged, order matters but in combination the order does not matter.

We have 18 people on a basketball team.

The coach needs to choose 5 to put into a game.

So the total different possible ways can the coach choose a team of 5 if each person has an equal chance of being selected is:

\(= \rm _{18}^{}\textrm{C}_5\)

\(= \dfrac{18!}{5!\times 13!}\)

= 8568

Thus, the total different possible ways can the coach choose a team of 5 if each person has an equal chance of being selected is, 8568 or C(18, 5)

We have established that the answer to the equation,  \(x = 24/7\) , is that the left side equals the right side.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation \(3x + 5 = 14\)  consists of the two equations  \(3x + 5\) and 14, which are separated by the 'equal' sign.

The equation is as follows:

\(\frac{1}{2}\times (x-2)+ 1+2/3x-3\)

This equation can be made simpler by first merging like terms:

\(\frac{1}{2}\times (x-2)+ 1+2/3x-3\)

\(= 1/2x + 2/3x - 4\)

\(= 7/6*x - 4\)

As a result, the equation becomes \(7/6*x - 4 = 0.\)

We can now get the value of x by multiplying both sides by 6/7 after adding 4 on both sides: \(7/6*x = 4 x = 24/7.\)

We rewrite the original equation with x = 24/7 to confirm the solution:

\(1/2*(24/7-2)+1+2/3(24/7)-3\)

\(= 1/2*(10/7)+1+16/21-3\)

\(= 5/7+1-2/3\)

\(= 6/7\)

Therefore, 6/7 demonstrates the equality.

The equation that is the same as y = 3 cos(2 (x + π/2)) - 2 is y = -3 sin (2(x + π/4)) -2

We have the original equation as;

y = 3 cos(2 (x + π/2)) - 2

The sine and cosine functions are related by the formula;

cos(θ) = sin (π/2 - θ)

Hence;

y = 3 cos(2 (x + π/2)) - 2

y = 3 cos(2x + π) - 2

When θ = 2x + π, it follows that:

cos(2x + π) = sin (π/2- (2x + π))

= sin (-2(x + π/4))

Since

sin(-θ) = -sin (θ)

Then:

sin (-2(x + π/4)) = -sin (2(x + π/4))

So

sin (2(x + π/4)) = cos(2x + π)

Finally;

y = -3 sin (2(x + π/4)) -2

Thus, standard error for this sample of tissue cells infected in a laboratory treatment is 5.33.

The standard error (SE) is a measure of how much the sample mean deviates from the population mean. It is calculated as the standard deviation of the sample divided by the square root of the sample size.

In this case, the sample size is 225, the standard deviation is 80, and the mean is 350. Therefore, the standard error can be calculated as follows:

SE = 80 / √(225)
SE = 80 / 15
SE = 5.33

The standard error for this sample of tissue cells infected in a laboratory treatment is 5.33. This means that the sample mean of 350 is likely to be within 5.33 units of the population mean.

The smaller the standard error, the more precise the estimate of the population mean. In this case, the standard error is relatively small compared to the standard deviation, which suggests that the sample mean is a relatively accurate estimate of the population mean.

However, it is important to note that the standard error only provides information about the precision of the estimate, not its accuracy. Other factors, such as sampling bias or measurement error, could still affect the accuracy of the estimate.

Raphael could finish the job in 3/2 hr = 90 min. Matilde could finish the job in 3 hr.

Let M denote for matilde

R for Raphael.

I assume they worked on the task together to finish it in 1 hr.

M does 1/M of the job per hr.

R does 1/R of the job per hr.

(1/M + 1/R) * x hr = 1 whole job completed

We are told x = 1 hr, so that's done.

We are told M's rate of work is 1/2 of R's

R's rate of work is 1/R

1/2 * 1/R = 1/2R

substitute 1/2R for 1/M

(1/2R + 1/R) * 1 hr = 1 whole job completed

solve

(R+ 2R)/ 2R^2 = 1

3R /2R^2 = 1

3R = 2R^2

2R^2 -3R = 0

R(2R-3) = 0

R = 0 or 2R = 3

However, if R could do the work in 0 hours, then his rate of work would be undefined.

Therefore, we select 2R = 3, which means R= 3/2.

R can do the whole job in 3/2 hr working alone.

M can do the whole job in 2*3/2 = 3 hr working alone.

We can check this solution to be sure it is correct.

In 1 hr, R can do 2/3 of the job.

In 1 hr, M can do 1/3 of the job

2/3+1/3 = 1.

We also can substitute in the original equation as double-check.

(1/3 + 1/(3/2))*1 = 1 ??

(1/3 + 2/3) = 1

Answer: R could finish the job in 3/2 hr = 90 min. M could finish the job in 3 hr.

The probability of landing heads exactly 11 times when a coin is tossed 20 times is option a) 0.1602

The repeated tossing of a coin follows a binomial distribution

P(X = x) = ⁿCₓ pˣ (1 - p)⁽ⁿ ⁻ ˣ⁾

where,

n = No. of times the experiment was repeated

x = random variable defining the number of "successes"

p = probability of "success"

Here

"succeess" is the event of landing a head.

n = 20

x = no. of times heads should show, i.e 11

p = probability of landing a head in a single toss

= 1/2

Hence, putting all this in the formula above we get

P(X = 11) = ²⁰C₁₁ 0.5¹¹ (1 - 0.5)⁽²⁰ ⁻ ¹¹⁾

= ²⁰C₁₁ 0.5¹¹ 0.5⁹

First, we need to find the coordinates of each vertex of triangle ABC. Let's assume that A is located at (a,b), B is located at (c,d), and C is located at (e,f). Since we know the measures of the angles, we can also determine the slopes of the lines connecting the vertices:

The slope of line AB is (d-b)/(c-a), which is equal to tan(55°).

The slope of line BC is (f-d)/(e-c), which is equal to tan(80°).

The slope of line AC is (f-b)/(e-a), which is equal to tan(55°-45°) = tan(10°).

Using these slopes, we can find the equations of the three lines and solve for the coordinates of the vertices:

Line AB: y-b = tan(55°)(x-a)

Line BC: y-d = tan(80°)(x-c)

Line AC: y-b = tan(10°)(x-a)

Solving these equations simultaneously, we get:

A = (b + (c-a)tan(55°), b + (c-a)tan(55°-45°))

B = (c + (f-d)/tan(80°), d + (f-d))

C = (e + (b-f)/tan(10°), f + (e-a)tan(10°))

Next, we need to apply the rotation and reflection to these vertices to find the corresponding vertices of triangle XYZ. The rotation by 90° counterclockwise about the origin transforms a point (x,y) into (-y,x), while the reflection across the line y=x transforms a point (x,y) into (y,x). So:

Vertex A of ABC is mapped to vertex X of XYZ: (a,b) → (-b,a) → (a,-b)

Vertex B of ABC is mapped to vertex Y of XYZ: (c,d) → (-d,c) → (c,d)

Vertex C of ABC is mapped to vertex Z of XYZ: (e,f) → (-f,e) → (e,f)

Now we need to find the measure of angle Y. Since we don't know the exact coordinates of the vertices of XYZ, we'll use the fact that the rotation by 90° counterclockwise about the origin preserves angles and the reflection across the line y=x changes the orientation of angles but not their measure. Therefore:

m∠Y = m∠ZOX, where O is the origin

m∠ZOX = 90° - m∠XOZ

m∠XOZ = m∠COA = 55° + 45° = 100°

Therefore, m∠Y = 90° - 100° = -10°, but since angles can't have negative measures, we add 360° to get m∠Y = 350°.

So the measure of angle Y in triangle XYZ is 350°.
