The error that was made is found in; C: Step 3 and it can be corrected by Setting the width greater than.

When trying to construct a line tangent to circle O at a point say P, the steps are as follows;

Step 1; Draw a line from the center through P and beyond the circle.

Step 2; With the compass on P, draw an arc each side of P, creating Q and R.

Step 3; With the compass on Q, set its width to a setting greater than QP.

Step 4; Make an arc in a random location using Q as center with distance less than QR but greater than QP.

Step 5; Without changing the compass width, repeat step 4 for point R, creating point S.

Step 6; Draw a line through P and S.

Step 7; PS is the line tangent to circle O at point P

Looking at the steps and comparing to the question, it is clear that the error was in step 3 where they made the compass on Q equal to QP rather than greater than QP.

Answer:

[tex]\sf \cos ^2\left(x\right)[/tex]

Explanation:

[tex]\sf \sin \left(x\right)\csc \left(x\right)+\cos \left(\frac{3\pi }{2}-x\right)\sin \left(x\right)[/tex]

[tex]\sf \sin \left(x\right)\csc \left(x\right)+\left(-\sin \left(x\right)\right)\sin \left(x\right)[/tex]

[tex]\sf \sin \left(x\right)\csc \left(x\right)-\sin ^2\left(x\right)[/tex]

[tex]\sf \cos ^2\left(x\right)[/tex]

Answer:

[tex]\cos^2(\theta)[/tex]

Step-by-step explanation:

Identities used:

[tex]\csc(\theta)=\dfrac{1}{\sin(\theta)}[/tex]

[tex]\cos(\frac{3 \pi}{2}-\theta)=\cos(\frac{3 \pi}{2})\cos(\theta)+\sin(\frac{3 \pi}{2})\sin(\theta)[/tex]

[tex]\textsf{As }\cos(\frac{3 \pi}{2})=0\textsf{ and }\sin(\frac{3 \pi}{2})=-1[/tex]

[tex]\implies \cos(\frac{3 \pi}{2}-\theta)=0 \times\cos(\theta)+-1\times\sin(\theta)=-\sin(\theta)[/tex]

[tex]\sin^2(\theta)+\cos^2(\theta)=1 \implies \cos^2(\theta)=1-\sin^2(\theta)[/tex]

Therefore,

[tex]\sin(\theta) \times \csc(\theta)+\cos(\frac{3 \pi}{2}-\theta)\times\sin(\theta)[/tex]

[tex]=\sin(\theta) \times\dfrac{1}{\sin(\theta)}-\sin(\theta)\times\sin(\theta)[/tex]

[tex]=1-\sin^2(\theta)[/tex]

[tex]= \cos^2(\theta)[/tex]

Using the normal distribution and the central limit theorem, it is found that there is a 0.2033 = 20.33% probability that Becky’s proportion of poses held for over a minute is greater than Carla’s.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

For each sample, we have that:

[tex]p_B = 0.29, s_B = \sqrt{\frac{0.29(0.71)}{50}} = 0.046[/tex]

[tex]p_C = 0.35, s_C = \sqrt{\frac{0.35(0.65)}{50}} = 0.057[/tex]

For the distribution of the difference of the proportions of Becky and Carla, we have that:

[tex]\mu = p_B - p_C = 0.29 - 0.35 = 0.06[/tex]

[tex]s = \sqrt{s_B^2 + s_C^2} = \sqrt{0.046^2 + 0.057^2} = 0.073[/tex]

The probability that Becky’s proportion of poses held for over a minute is greater than Carla’s is the probability that the subtraction is above 0, that is, 1 subtracted by the p-value of Z when X = 0, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0 + 0.06}{0.073}[/tex]

[tex]Z = 0.82[/tex]

[tex]Z = 0.82[/tex] has a p-value of 0.7967.

1 - 0.7967 = 0.2033.

0.2033 = 20.33% probability that Becky’s proportion of poses held for over a minute is greater than Carla’s.

The equation that best represents this relationship is y = 8x

The standard linear equation is expressed as y = mx + b

writing the given information in a coordinate form (x, y) will give (18, 144) and (22, 176)

Determine the slope "m"

Slope = 176-144/22-18
Slope = 32/4
Slope = 8

Detremine the y-intercept

144 = 8(18) + b

b = 144 - 144
b = 0
Hence the equation that best represents this relationship is y = 8x

It can be deduced that the probability of having 4 or more correct guesses will be 0.0296.

From the given information, the null hypothesis is p = 1/7 and the alternate hypothesis is p>1/7. In this case, the mind reader gets a 4 out of 9 chances.

In order to test the hypothesis, simulations for 10000 cases were run with a probability of the correct answer being 1/7.

In this case, the p-value is the probability of correct answers that are greater than 4, assuming the null hypothesis is true. Here the p-value is 0.0296.

Also, the significance level to reject the hypothesis is less than 0.01. Since p > 0.01, we then fail to reject the hypothesis. Therefore the null hypothesis stands and Joao is not a mind reader.

Answer:

m = - 2 , c = 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, 8 ) and (x₂, y₂ ) = (3, 0 )

m = [tex]\frac{0-8}{3-(-1)}[/tex] = [tex]\frac{-8}{3+1}[/tex] = [tex]\frac{-8}{4}[/tex] = - 2 , then

y = - 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

using (3, 0 )

0 = - 6 + c ⇒ c = 0 + 6 = 6

99/1=99

Step-by-step explanation:

The largest possible quotient that has a 1-digit divisor and 2-digit dividend will be 99.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Division means the separation of something into different parts, sharing of something among different people, places, etc.

The smallest one-digit number is 1 and the largest two digits number is 99. Then the largest possible quotient will be given as,

⇒ 99 / 1

⇒ 99

The largest possible quotient that has a 1-digit divisor and 2-digit dividend will be 99.
