Answer:

Andrew is incorrect.

Step-by-step explanation:

He is incorrect because instead of multiplying 2 x 28, he should have did 2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2, which is 268,435,456.

If he wants an average of 84, he needs to get at least 93 points.

Remember that the average value between 3 values A, B, and C is:

(A + B + C)/3

Here we know that the first two scores are 76 and 83 points, let's say that the third score is x, if we want to have an average of 84 or more, then we need to solve:

(76 + 83 + x)/3 = 84

159 + x = 252

x = 252 - 159

x = 93

So he needs to get at least 93 points in the next exam.

Answer:

A 98% confidence interval for the true proportion of Americans who were satisfied with the gun control laws in 2018 is (0.213, 0.387).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.

\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)

In which

z is the zscore that has a pvalue of \(1 - \frac{\alpha}{2}\).

For this problem, we have that:

\(n = 150, \pi = 0.3\)

98% confidence level

So \(\alpha = 0.02\), z is the value of Z that has a pvalue of \(1 - \frac{0.02}{2} = 0.99\), so \(Z = 2.327\).

The lower limit of this interval is:

\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3 - 2.327\sqrt{\frac{0.3*0.7}{150}} = 0.213\)

The upper limit of this interval is:

\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3 + 2.327\sqrt{\frac{0.3*0.7}{150}} = 0.387\)

A 98% confidence interval for the true proportion of Americans who were satisfied with the gun control laws in 2018 is (0.213, 0.387).

Step-by-step explanation:

we can conclude that Probability of both Lucy and Zaki hitting the target is 0.4.

According to the statement

we have to find the probability that the both Lucy and Zaki hit the target.

So, For this purpose, we know that the

Probability is the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.

So, From the given information:

When Zaki or Lucy throw a ball at the target there are only two outcomes for each of them ( i.e Hit or miss )

Therefore :

The probability of Lucy hitting the target = 0.4/2

And

The probability of Zaki hitting the target = 0.2+0.2/2

So,

The Probability of both Lucy and Zaki hitting the target is:

P(Lucy ) + P(Zaki ) = 0.4/2 + 0.4/2

P(Lucy ) + P(Zaki ) = 0.8/2

P(Lucy ) + P(Zaki ) = 0.4

Hence,

we can conclude that Probability of both Lucy and Zaki hitting the target is 0.4.

Answer:

\(\boxed {\tt 69.08 \ centimeters}\)

Step-by-step explanation:

The circumference of a circle can be found using the following formula:

\(c= \pi d\)

where d is the diameter. We know the diameter of the circle is 22 centimeters. Substitute the value in for d.

\(d= 22 \ cm\)

\(c= \pi* 22 \ cm\)

We also know we are using 3.14 for pi. Substitute it in for pi.

\(c= 3.14 * 22 \ cm\)

Multiply.

\(c=69.08 \ cm\)

The circumference of the circle is 69.08 centimeters.

Answer:

Circumference = 69.08 cm

Step-by-step explanation:

Diameter = 22

Radius = 22/2

= 11

Circumference = 2πr

= 2 × 3.14 × 11

= 69.08 cm

The missing term when using the square root method is the discriminant. The discriminant is a number that is calculated from the coefficients of a quadratic equation.

A quadratic equation is a type of mathematical equation that can be written in the form of ax² + bx + c = 0, where a, b, and c are real numbers, a cannot equal 0. It is called a quadratic equation because it has a second-order term, which is the x² term. This type of equation has two solutions, which are referred to as the roots. These roots can be found by using the quadratic formula, which is x = -b ± √(b² - 4ac) / 2a. This equation can be used to solve a wide variety of problems, including finding the length of a side in a right triangle, calculating the area of a circle, finding the maximum or minimum of a function, and solving systems of linear equations.

The calculation of this can be done by first determining the future value of the monthly payments of $327.50

The future value of an annuity can be determined using a financial calculator, mathematical formula, or spreadsheet software. The future value of an annuity is calculated by multiplying the periodic payment amount by the future value factor,

which is based on the number of payments and the interest rate.For example, suppose we want to know the future value of a $500 end-of-month deposit into an annuity that pays 6% interest compounded monthly for five years.

The future value factor for 60 periods at 0.5 percent per month is 80.9747, which can be multiplied by the monthly deposit amount to find the future value of the annuity.500 × 80.9747 = 40,487.35

This means that a $500 end-of-month deposit into an annuity paying 6% interest compounded monthly for five years will have a future value of $40,487.35.

Therefore, to accumulate a $20,000 down payment for a home in five years, you would need to deposit $327.50 per month into the annuity.

 for 60 months using the formula and then solving for the monthly payment amount where FV = $20,000 and n = 60, r = 0.5%.FV = PMT [(1 + r)n – 1] / r$20,000 = PMT [(1 + 0.005)60 – 1] / 0.005PMT = $327.50 (rounded to the nearest cent).

Answer:

Step-by-step explanation:

Hello!

The variable of interest is

X: data speed of a particular smartphone carrier in one airport.

n= 50 airports

X[bar]= 18.39 Mbps

S= 31.86 MBps

The highest speed recorded X= 76.6 Mbps

a.

The difference between the highest speed and the mean is:

X-X[bar]= 76.6-18.39= 58.21 Mbps

b.

To calculate how many standard deviations away from the mean the highest speed is, you have to divide it by the standard deviation:

\(\frac{X-X[bar]}{S} = \frac{58.21}{31.86}= 1.82\)

c.

The standard normal distribution is tabulated. Any value of any random variable X with normal distribution can be "converted" by subtracting the variable from its mean and dividing it by its standard deviation. This is exactly what you did in items a. and b., so the Z score is

Z= 1.82

d.

-2 ≤ Z ≤ 2⇒ the calculated Z value is within both limits, so the carrier's highest data speed is not significant.

I hope this helps!

Tea is offered to every visitor as a sign of hospitality, and not offering tea would be considered impolite.

A circle is a two-dimensional shape that is defined as a set of all points in a plane that are equidistant from a fixed point called the center. The distance between the center and any point on the circle is called the radius, which is a constant value for all points on the circle.

A circle can be represented by its center point and radius or by its diameter, which is the distance across the circle passing through its center. Circles have several important properties, such as their circumference (the distance around the outside of the circle), their area (the amount of space enclosed by the circle), and their diameter (the longest distance across the circle).

Circles are used in many areas of mathematics, physics, engineering, and other sciences. They are also used in everyday life, such as in the design of round objects like wheels and in the creation of circular patterns in art and architecture.

A circle graph, also known as a pie chart, is a type of data visualization that displays data as a circular graph, divided into sectors that represent numerical proportions.

Each sector of the circle represents a percentage or proportion of the total data set, and the size of each sector is proportional to its corresponding value.

To find m EF, we need to add the percentages of participation in sports E and F:

m EF = percentage of participation in sports E + percentage of participation in sports F

m EF = 11% + 14%

In a box-and-whisker plot, the box represents the interquartile range (IQR), which includes the middle 50% of the data.

The line within the box represents the median.

The "whiskers" extend to the minimum and maximum values, excluding any outliers.

Given the information provided:

Median = 41

Q1 = 37

Q3 = 49

Largest = 55

Smallest = 35

Since Q3 represents the upper quartile and corresponds to the boundary for the upper 25% of the data, we can conclude that 25% of the employees took a break longer than 49 minutes.

Now,

The number of employees who took a break longer than 49 minutes can be estimated by calculating 25% of the total number of employees:

25% of 27 employees

= (25/100) x 27

= 6.75

Since we cannot have a fractional number of employees, we round up to the nearest whole number.

Therefore,

Approximately 7 employees took a break longer than 49 minutes.
