Answer:

1.07^(-2)

Step-by-step explanation:

First, figure out what 10 to the fourth power is. This will give us 10,000.

Now, divide 107 by 10,000. That gives us 0.0107. Now put this in exponential.

In expoential, we get 1.07^(-2)

For a line with a slope a and a known point (h, k), the point-slope form is:

y = a*(x - h) + k

A general linear equation can be written in slope-intercept form as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we know that a line passes through a point (h, k), then the point-slope form of that line is:

y = a*(x - h) + k

Notice that particularly, the y-intercept can be written as (0, b), then the slope-intercept form is also a point-slope:

y = a*(x - 0) + b

y = a*x + b

In statistics, the risk of making an error is referred to as a significance level. A significance level represents the probability of making a Type I error, which occurs when a null hypothesis is rejected even though it is true.

The most common significance level used in statistical analyses is 0.05 or 5%. This means that there is a 5% chance of rejecting a true null hypothesis.

In general, the choice of significance level depends on the specific application and context of the statistical analysis.

The 5% significance level is commonly used in scientific research, particularly in the fields of medicine and psychology.

The choice of this level is based on a balance between the risk of making a Type I error and the risk of making a Type II error, which occurs when a null hypothesis is not rejected even though it is false.

A Type II error is often more serious than a Type I error since it may lead to incorrect conclusions about the relationship between variables or the effectiveness of a treatment or intervention.

A 5% significance level provides a reasonable balance between these two types of errors. However, in some situations, a higher or lower significance level may be more appropriate.

For example, in a clinical trial where the consequences of a Type II error are severe, a lower significance level may be used to reduce the risk of this type of error.

The diameter of the circle is 4.2 units    

The set of circles that have the same radius and same size are known as Congruent circles. In other words, the circles which have the same radius same are known as Congurents circles

Here we have

Circles P and Q are congruent and m∠O = 90°. and RQ = 5

From the data, Circles P and Q are congruent  

Hence, the Radius of Circles P and Q are the same

=> PR = RQ

=> PQ = PR + RQ = 5 + 5  [ Since RQ = 5 = PR ]

=> PQ = 10 ---- (1)

Since, PR = RQ the center, 'O' will be at the same distance from P and Q

=> QO = PO --- (2)

Given that m∠O = 90°  

This implies PQO is an isolated right triangle  

As we know in a right triangle    

=> Hypotenuse² = side² + side²  

=> PQ² = QO² + PO²    

=> (10)² = 2QO²    [ from (1) ]

=> 100 = 2 QO²

=> QO² = 50

=> QO = √50 = 5√2

=> QO = 7.07

From the figure,

The radius of the circle = OQ - Radius of circle Q  

= 7.07 - 5 = 2.1  

Hence, the diameter of the circle = 2 × 2.1 = 4.2

Therefore,

The diameter of the circle is 4.2 units

Derrick will receive total of $340 from all of his deductions

To create a histogram for these values using four classes, we must first determine the class width, which is determined as the data range divided by the number of classes. The data range is 151 - 58 = 93, which is the difference between the biggest and smallest numbers. The breadth of the class is 93/4 = 23.25. We'll round it up to 24 because we can't have a fractional class width.

Then, for each of the four classes, we'll start with the smallest number (58) and add the class width (24) again until we reach the maximum value (151). The lowest class boundaries for the four classes are as follows:

Class 1: 58

Class 2: 82

Class 3: 106

Class 4: 130

We'll determine the upper class limit for each lower class limit by adding the class width (24) - 1. The upper class restrictions are as follows:

Class 1: 81

Class 2: 105

Class 3: 129

Class 4: 153

Finally, we'll tally the amount of deductions made in each class and utilise that data to create the histogram. Each class has the following number of deductions:

Class 1: 1 (58)

Class 2: 3 (97, 98, 101)

Class 3: 3 (103, 127, 144)

Class 4: 3 (144, 151, 65)

We can compute the total amount Derrick will earn from all of his deductions now that we know the number of deductions in each class. He will earn $25 for each deduction of less than $130, and $45 for each deduction of $130 or more.

Derrick will receive the following total from all of his deductions:

$25 * 1 (for the single deduction of less than $130) + $45 * 7 (for the seven deductions of $130 or over) = $25 + $315 = $340

The four angles, one in each quadrant, with a common reference angle of with 285° are: 15°, 165°, 195°, 345°

A common reference angle is an angle that is shared by multiple angles in different quadrants when measured from the x-axis. The reference angle for an angle measured in degrees can be found by subtracting the nearest multiple of 90 degrees that is less than the angle.

For the angle 285°, the nearest multiple of 90 degrees that is less than it is 270°. Therefore, the reference angle for 285° is 285° - 270° = 15°.

Using this reference angle, we can find an angle in each quadrant with a common reference angle with 285° as follows:

Answer:

C

Step-by-step explanation:

The radius is 7, but in the standard form for a circle, the radius is squared which means that the answer is NOT A and B.

So now you have only two choices, C and D both of which have the radius shown as 49 which is 7 squared.

The center is at (5,-1)

that means that x will be written as (x - 5)

And y will be written as (y + 1)

Note: the signs of the center always change to the opposite of what they were.

The answer is (x - 5)^2 + (y  + 1)^2 = 49

Answer:

\( \hat p=\frac{0.56137+0.60529}{2}= 0.58333\)

The critical value for 95% of confidence is \(z_{\alpha/2}=1.96\)

And since we know the total and the proportion is defined as:

\( \hat p=\frac{X}{n}\)

If we solve for X (number of people who say yes) we got:

\( X= 0.58333* 504= 293.998 \approx 294\)

And the best answer would be:

294

Step-by-step explanation:

We know that the confidence interval for the proportion is given by:

\( \hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}\)

The margin of error for the proportion interval is given by this formula:  

\( ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}\)    (a)  

The margin of error can be calculated with this formula:

\( ME=\frac{0.60529- 0.56137}{2}= 0.02196\)

And the estimation for the true proportion is:

\( \hat p=\frac{0.56137+0.60529}{2}= 0.58333\)

The critical value for 95% of confidence is \(z_{\alpha/2}=1.96\)

And since we know the total and the proportion is defined as:

\( \hat p=\frac{X}{n}\)

If we solve for X (number of people who say yes) we got:

The percentage of boys in the class and also the standard deviation of heights of all the students in the class are 78% and 9 cm respectively

Percentage of the boys in the class deals with a ratio of the boys to the number of students in the class

The given parameters that will help us to get the percentage are

Mean height of the class = 152 cm

Mean height of the boys = 158 cm

The standard deviation of the boys = 5 cm

Mean height of the girls = 148 cm

Standard deviation of the girls = 4 cm

(1) The percentage of boys in the class is

Total mean height = 158 +148 = 306

Percentage = 158/306 * 100 = 51.6%

Then the  percentages 51.6/100 * 152 = 78%

(2) The total standard deviation of all the students

Boys + girls = 5+4 = 9 cm

Therefore, the percentage of boys in the class and also the standard deviation of heights of all the students in the class are 78 students and 9 cm respectively

Answer:

0.8418

Step-by-step explanation:

We have p = 0.36

Sample size = 200

We have to find the standard error of proportion

= √p(1-p)/n

= √0.36(1-0.36)/200

= 0.034

P(0.30<p^0.40)

= 0.30-0.36/0.034 = -1.76,

0.40-0.36/0.034 = 1.18

P(-1.76<z<1.18)

When we go to the standard normal distribution table

P(z<1.18) = 0.8810

P(z<-1.76) = 0.0392

0.8810 - 0.0392

= 0.8418

This is the probability of the sample proportion being between 0.30 and 0.40
