Answer: 80

Step-by-step explanation:

280-47=233 people who like cats or dogs

153+138=291 people who like cats, dogs, or both

statement CBA ≅ TWR is true.

The theorem that states that two triangle is congruent when there three corresponding sides are equal and all three corresponding angles are also equal.

given, triangle ABC and Triangle RWT both are right-angled.

we examined that three corresponding sides of ABC is equal to the corresponding sides of RWT and same for the three corresponding angles.

we measured, right angle A = right angle R

base length AB = base length RW

hypotenuse BC = hypotenuse WT

Side length AC = side length RT

angle C = angle T

angle B = angle W

as per the properties of congruence theorem ABC and RWT are congruent.

hence the statement CBA ≅ TWR is true.

Answer:

The data has an outlier in the 13 to 15 range and shows that a large group purchased tickets to the game.

Step-by-step explanation:

An outlier in a frequency distribution is a value or set of values that is significantly different from the rest of the data set points. There is not a strong mathematical definition for what an outlier is, one should examine the data and assess in a more or less subjective manner

Looking at the data we see that most of ticket sales fall in the range 1-10

There is nothing in the range 10-12 but then after that there is another interval 13-15 with a frequency count of 1. This interval represents an outlier - it is very much apart from the rest of the data

So statement 1 is the best choice

We can eliminate the second statement. Skewness means that the data is very asymmetrical and has a peak which is at extreme right or left. Looking at the graph we see that the data is pretty much symmetrical in the range 1 - 10

Third statement can be easily eliminated since we do have an outlier as explained

Fourth statement can also be easily eliminated. The mode of a distribution is the value  that appears the most often. When plotting a histogram this value (interval will have the bar that is tallest). Here, the mode is in the interval 4-6 with a height of 16 which is the number of times any ticket sales in the range 4-6 occur.

A bimodal distribution will have two bars which are the highest and of equal value. We usually refer to these as peaks. Here there is only one peak and such a distribution is called a unimodal distribution.

Hope that helps you :)

I got it right on my quiz

Adrian must multiply his money by 1.03 to find his total balance in a year in one step.

The following calculation must be done in order to determine what Adrian should multiply his current balance by in order to find his total balance in a year in one step, assuming that no money will be added to or subtracted from the investment. Adrian invests money in an account that offers simple interest of 3% per year.

Current balance = X

Interest = 3% = 3/100 = 0.03

Interest + principal = 1.03

1.03X = Total balance in a year

Therefore, Adrian must multiply his money by 1.03 to find his total balance in a year in one step.

The equation that represents the linear function is y =32x

What is a linear equation explain?

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

                            The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.

A linear function is represented as

                    y = mx + c

The slope is calculated as

          m = y₂ - y₁/x₂ - x₁

        m = 576 - 64/18 - 2

        m = 512/16

         m = 32

The linear equation is then calculated as

        y = 32( x - 2 ) + 64

         y = 32x - 64 + 64

          y =  32x

Hence, the equation that represents the linear function is y =32x

The total number of oranges that the trader bought is 31

A trader bought some oranges at the price of #50 each

He finds that Six of these oranges are rotten

He sells the remaining at #80

He makes a profit of #450

Therefore the number of oranges that the trader bought is

Let y represent the number of oranges that the trader bought

At a price of #50= 50x

6 oranges were rotten= x-6

Profit = 450

450= 80(x-6)-50x

450= 80x-480-50x

450= 80x-50x-480

450= 30x-480

450+480= 30x

930= 30x

x= 930/30

Answer:

3.981071706 x 10^5

Step-by-step explanation:

In standard form, a number is written as a decimal multiplied by a power of 10. To convert 398107.1706 to standard form, we can move the decimal point until we have a number between 1 and 10 and a power of 10 that will make the original number.

398107.1706 = 3.981071706 x 10^5

Answer:

The amount of money in the account at the end of 5 years is $9,841.63.

Step-by-step explanation:

The compound interest formula is A = P(1 + r/n)^(nt) where A is the final amount, P is the principal (initial deposit), r is the annual interest rate (expressed as a decimal), n is the number of times interest is compounded per year, and t is the number of years.

In this case, P = 8000, r = 0.04, n = 4 (because interest is compounded quarterly), and t = 5 (because we are trying to find the balance after 5 years).

So the formula becomes:

A = 8000(1 + 0.04/4)^(4*5)

By plugging the number into the formula we can find the final amount after 5 years

A = $9,841.63

The amount of money in the account at the end of 5 years is $10,404.69, and the interest earned is $2404.69.

To calculate the amount of money in the account at the end of 5 years, we need to use the compound interest formula: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

To calculate the amount of interest earned, we subtract the initial deposit from the final amount: interest = A - P.

b. -2

An imaginary number is a number which is obtained by finding the square root of a negative number.

The specified expression is; [tex]\frac{x+2\cdot \mathbf{i}}{1 + \mathbf{i}}[/tex]

Multiplying the numerator and the denominator by the complex conjugate of the denominator, (1 - i), we get;

[tex]\frac{x+2\cdot \mathbf{i}}{1 + \mathbf{i}}\times \frac{1 - \mathbf{i}}{1 - \mathbf{i}} =\frac{x - x \cdot \mathbf{i}+2 \cdot \mathbf{i}-2\cdot \mathbf{i}^2}{1 - \mathbf{i}^2}[/tex]

[tex]\frac{x - x \cdot \mathbf{i}+2 \cdot \mathbf{i}-2\cdot \mathbf{i}^2}{1 - \mathbf{i}^2} = \frac{x + (2 - x)\cdot \mathbf{i} + 2}{1 - (-1)} =\frac{x + (2 - x)\cdot \mathbf{i} + 2}{2}[/tex]

Where x is real, for the number to be purely an imaginary number, we get;

[tex]\dfrac{x + (2 - x)\cdot \mathbf{i} + 2}{2} = \dfrac{x +2+ (2 - x)\cdot \mathbf{i} }{2} = \dfrac{0+ (2 - x)\cdot \mathbf{i} }{2}[/tex]

[tex]\frac{0+ (2 - x)\cdot \mathbf{i} }{2} = \frac{(2 - x)\cdot \mathbf{i} }{2} = \frac{(2-x)}{2} \cdot \mathbf{i}[/tex]

Therefore, for the number to be a purely imaginary number, then; x + 2 in the numerator following the multiplication of the numerator and the denominator by the complex conjugate of 1 + i, which is 1 - i, should be 0, and we get;

x + 2 = 0

x = 0 - 2 = -2

x = -2

The value of x such that the expression (x + 2·i)/(1 + i) is a purely imaginary number is; x = -2

Time = Distance / Speed

Given that Kyle's parents travel at a constant speed of 40 km/h and the distance from their house to school is 60 km, we can substitute these values into the formula:

Time = Distance / Speed = 60 km / 40 km/h

To convert the answer from hours to minutes we have to multiply the result by 60.

Time = (60 km / 40 km/h) * 60 = 1.5 * 60 = 90 minutes
