Zach just got a grade of 93 on a report. However, because he turned it in late, his teacher is going to deduct 15 points. What will Zach's final score on the report be?​

Answer:

2

Step-by-step explanation:

2 x 1250 = 2500

the perfect square for 2500 is 50:

\(\sqrt{2500} = 50\)

The appropriate distribution to use in this case is the discrete probability distribution since the number of missed days of employees at the shoe store is limited to specific values with associated probabilities.

In a discrete probability distribution, the random variable can only take on specific, separate values with associated probabilities. In this scenario, the number of missed days of employees at the shoe store can only take values from 0 to 10, which are distinct and separate values.

To construct the discrete probability distribution, we need to know the probabilities associated with each possible number of missed days. These probabilities will determine the likelihood of each outcome occurring. The sum of all probabilities should be equal to 1, as it represents the total probability of all possible outcomes.

Once we have the probabilities for each possible number of missed days, we can plot the distribution and analyze the likelihood of different outcomes. The distribution will provide insights into the frequency and probability of various levels of employee absenteeism at the shoe store.

Sine is the ratio of the length of the side opposite to the angle to the hypotenuse of the right triangle.

Answer:

The dotted line is 4.9

Step-by-step explanation:

The lower triangle is a right triangle so we can use the Pythagorean theorem

a^2+b^2 = c^2

where a and b are the legs and c is the hypotenuse

2^2 + 4^2 = c^2

4+16 = c^2

20 =c^2

Taking the square root of each side

sqrt(20) = c

The upper rectangle has a length of sqrt(20) and a height of 2

We can use the  Pythagorean theorem

a^2+b^2 = c^2

where a and b are the legs and c is the hypotenuse  to find the  diagonal

2^2 + (sqrt(20))^2 = c^2

4+20 = c^2

24 = c^2

Taking the square root of each side

sqrt(24) = c

4.898979486=c

Rounding to the nearest tenth

4.9 =c

The remainder when the original number is divided by 130 is 0 using Chinese Remainder Theorem.

To solve this problem, we need to use the Chinese Remainder Theorem. Since the number has a remainder of 3 when divided by 10 and a remainder of 3 when divided by 13, we can write it as:

x ≡ 3 (mod 10)
x ≡ 3 (mod 13)

To find the solution, we can use the following steps:

Step 1: Find a solution to each congruence.

For the first congruence, we can see that x = 13k + 3 is a solution, where k is an integer. This is because any number of the form 13k + 3 will leave a remainder of 3 when divided by 10.

For the second congruence, we can use the same method and find that x = 10m + 3 is a solution, where m is an integer.

Step 2: Combine the solutions using the Chinese Remainder Theorem.

To combine the solutions, we need to find a number that satisfies both congruences. One way to do this is to use the equation:

x = aM(y)(b) + bM(x)(a)

where a = 10, b = 13, M(a) = 13, and M(b) = 10. Plugging in these values, we get:

x = 10(13)(y) + 13(10)(x)

Simplifying this equation, we get:

x = 130y + 130x - 130x + 130y

x = 260y

So any number of the form 260y will satisfy both congruences.

Step 3: Find the remainder when divided by 130.

To find the remainder when divided by 130, we can simply take the remainder of 260y when divided by 130. Since 260 is a multiple of 130, we know that the remainder will be 0. Therefore, the remainder when the original number is divided by 130 is 0.

Answer:

C, I got it right

Step-by-step explanation:

The two major types of series are the arithmetic series and the geometric series. The arithmetic series is characterized by common difference, while the geometric series has common ratio between two successive terms.

The sum of the given series is:

\(\lim_{n \to \infty} \frac{1}{3}(1 - \frac{1}{4}^n )\)

The given series is a geometric series. So, we first calculate the common ratio (r) using:

\(r = T_2 \div T_1\)

From the series, we have:

\(T_1 = \frac{1}{4}\)

\(T_2 = \frac{1}{16}\)

So, the equation becomes

\(r = \frac{1}{16} \div \frac{1}{4}\)

Rewrite as product

\(r = \frac{1}{16} * \frac{4}{1}\)

\(r = \frac{1}{4}\)

The formula to calculate the sum of a geometric series of is:

\(S_n = \frac{a(1 - r^n )}{1-r}\)

Where

\(a = T_1 =\frac{1}{4}\) -- the first term

\(S_n = \frac{\frac{1}{4}(1 - \frac{1}{4}^n )}{1-\frac{1}{4}}\)

Simplify the denominator

\(S_n = \frac{\frac{1}{4}(1 - \frac{1}{4}^n )}{\frac{3}{4}}\)

Divide 1/4 by 3/4

\(S_n = \frac{1}{3}(1 - \frac{1}{4}^n )\)

We can conclude that, the sum of the series is:

\(S_n = \lim_{n \to \infty} \frac{1}{3}(1 - \frac{1}{4}^n )\)

Simple interest and compound interest are the two methods for calculating interest. Simple interest is computed on a loan's principle, or initial loan amount. Compound interest is sometimes referred to as "interest on interest" since it is computed using both the principal and the accrued interest from prior periods.

Formula for Monthly Compound Interest. 12 times a year are used to compute interest that is compounded monthly., Formula for Quarterly Compounding. Four times a year are used to compute interest that is compounded quarterly., Formula for Daily Compound Interest., Formula for Annual Compound Interest.

To find the 59th term of an arithmetic sequence, we can use the formula:

a_n = a_1 + (n - 1) * d

where a_n represents the nth term of the sequence, a_1 is the first term, n is the position of the term in the sequence, and d is the common difference between consecutive terms.

In the given sequence, the first term (a_1) is 26, and the common difference (d) is -9 (subtracting 9 from each term to get to the next term).

Now we can substitute these values into the formula to find the 59th term:

a_59 = 26 + (59 - 1) * (-9)

= 26 + 58 * (-9)

= 26 - 522

Approximately 58.33% of the workers in the group are making over $25 an hour. The percentage was obtained by finding the area under the uniform distribution curve above the value of $25.

Since the hourly wages of the workers are uniformly distributed on the interval [20, 32], the probability density function is constant on this interval. The area under the probability density function between any two points a and b gives the probability that a randomly chosen worker's wage will be between a and b. Therefore, the probability that a worker's wage is above $25 is given by the area under the probability density function from 25 to 32, which is (32-25)/(32-20) = 7/12 or approximately 58.33%. Thus, approximately 58.33% of the workers are making over $25 an hour.

The formula for the volume of a cone is:

V = (1/3)πr²h

where r is the radius of the base, h is the height of the cone, and π is pi.

In this case, the slant height is given as 17 cm, which we can use with the radius to find the height of the cone using the Pythagorean theorem:

h² = s² - r²

h² = 17² - 8²

h² = 225

h = 15

Now that we have the height, we can plug in the values for r and h into the formula for the volume:

V = (1/3)π(8²)(15)

V = (1/3)π(64)(15)

V = (1/3)(960π)

V = 320π

Therefore, the volume of the cone is 320π cubic cm. Answer: 320π.

Step-by-step explanation:

In the equation y = $7.20x + $790, "y" represents the total cost. An equation is a mathematical statement that shows the relationship between two or more variables. In this equation, there are two variables - "x" and "y". The variable "x" represents the number of units produced or sold, while "y" represents the total cost.

The coefficient of "x" in the equation, which is 7.20, represents the variable cost per unit. This means that for each unit produced or sold, there is an additional cost of $7.20. The constant term, which is $790, represents the total fixed costs. Fixed costs are those costs that do not vary with the number of units produced or sold.To find the total cost of producing or selling a certain number of units, we can plug in the value of "x" into the equation and solve for "y". For example, if we want to find the total cost of producing 100 units, we can substitute x=100 into the equation:
y = $7.20(100) + $790
y = $720 + $790
y = $1510
Therefore, the total cost of producing 100 units is $1510. In summary, "y" represents the total cost in the given equation, which is determined by both fixed and variable costs.
In the equation y = $7.20x + $790, "y" represents option C: total costs. This equation has two components: "$7.20x" represents the variable costs per unit, where x is the number of units, and "$790" represents the total fixed costs. By adding these two components together, you get the total costs (y) for producing x units.

G = 3D - 2

substitute

4D - 2 = 46

4D = 46

D = 11.5

plug in D to either equation

G + (11.5) = 44

G = 32.5
