Write the equivalent of the fraction using a denominator of 52. 2/13

Answer:

0.225

Step-by-step explanation:

5 + 7 + 8 = 20 crayons.

we want 4 blue crayons from 15 draws. p(blue) = 5/20.

p(4 from 15 draws) = 0.225

The correct option of system of equations that can be used to find the temperature at which the degrees Celsius and the degrees Fahrenheit would be equivalent is the option;

5·F - 9·C = 160

F - C = 0

A system of equation, is a set of equation that have common variables.

The equation for conversion of the temperature in degrees Celsius to the temperature in degrees Fahrenheit is; 9·C = 5·F - 160

When the temperature in degrees Celsius is equivalent to the temperature in degrees Fahrenheit, we get;

F = C

Therefore;

F - C = 0

Similarly, from the specified equation, we get;

9·C = 5·F - 160

5·F - 9·C = 160

The system of equation that would give the temperature where the degrees Celsius and degrees Fahrenheit are equivalent is therefore;

5·F - 9·C = 160

F - C = 0

(Which yields a temperature of 40°)

To obtain 15 gallons of 24% alcohol, you would need to mix 14 gallons of 25% alcohol and 1 gallon of 10% alcohol.

To determine the amounts of 25% alcohol and 10% alcohol needed to obtain 15 gallons of 24% alcohol, we can set up an equation based on the principle of the mixture:

Let x represent the number of gallons of 25% alcohol.

Let y represent the number of gallons of 10% alcohol.

The equation can be set up as follows:

0.25x + 0.10y = 0.24  (15)

0.25x + 0.10y = 3.6

To solve this equation, we need another equation. Since we know that the total volume of the mixture is 15 gallons, we can add a second equation:

x + y = 15

Now we have a system of equations:

0.25x + 0.10y = 3.6

x + y = 15

Now, solving

x = 15 - y

Substituting this value of x into the first equation:

0.25(15 - y) + 0.10y = 3.6

3.75 - 0.25y + 0.10y = 3.6

-0.15y = -0.15

y = 1

and, x + 1 = 15

x = 14

Therefore, to obtain 15 gallons of 24% alcohol, you would need to mix 14 gallons of 25% alcohol and 1 gallon of 10% alcohol.

(b) His total amount to repay the loan is 50,895.6.

(c) The amount of interest he will pay is 10,395.6.

The Goran's monthly payment, is calculated using the following formula;

P = r(PV) / (1 - (1 + r)⁻ⁿ)

where;

r = 6.7% / 12 = 0.00558

PV = 40,500

n = 7 years x 12 months/year = 84 months

P = 0.00558(40,500) / (1 - (1 + 0.00558)⁻⁸⁴)

P  = 605.9

Total amount = 84 x 605.9 = 50,895.6

To solve the inequality 2x < 12, we need to isolate x on one side of the inequality sign. We can do this by dividing both sides by 2:

2x < 12

x < 6

Therefore, the solution to the inequality is x < 6. This means that all values of x that are less than 6 satisfy the inequality. We can represent this graphically on a number line:

<=======()------6-------------->

The open circle () indicates that x cannot be equal to 6, but can be any value less than 6. The arrow indicates that the inequality is true for all values of x to the left of the open circle.

In summary, the solution to the inequality 2x < 12 is x < 6.

The probability of getting 14 successes out of 19 trials with a probability of success of 0.8 is approximately 0.0572.

Using the binomial probability formula, we have:

P(X=14) = (n choose x) * pˣ . (1-p)⁽ⁿ⁻ˣ⁾

Plugging in the values, we get:

P(X=14) = (19 choose 14) x 0.8¹⁴ x 0.2⁵

P(X=14) ≈ 0.0572

Let's evaluate the inequality for each point:

1. Point (1, -1):

92 + 3(-1) < 6

92 - 3 < 6

89 < 6

The inequality is not true for this point.

2. Point (2, -2):

92 + 3(-2) < 6

92 - 6 < 6

86 < 6

The inequality is not true for this point.

3. Point (1, 1):

a)  Note that the the probability that on a given day, no machines break down is 0.3487

b) the probability that all printing   requirements on a particular day will be met is 0.2323

a) To find the probability that no machines break down, we can use the binomial distribution with

n = 10 (number of machines) and

p = 0.1 (probability of a machine breaking down).

The probability of no breakdowns  is

P(X = 0), where X is the number of breakdowns.

Using the binomial distribution formula: P(X = k) = (n choose k) * [tex]p^{k}[/tex] * (1 - p)[tex]^{n-k}[/tex]

P(X = 0) = (10 choose 0) * 0.1⁰ * 0.9¹⁰ = 0.3487

So it is right to stay that  the probability that on a given day, no machines break down is 0.3487

(b)

P(8 or more machines are functioning) = P(X = 8) + P(X = 9) + P(X = 10)

P(X = 8) = (10 choose 8) * 0.1⁸ *   0.9² = 0.1937

P(X = 9) = (10 choose 9) * 0.1⁹ * 0.9¹ = 0.0386

P(X = 10) = (10 choose 10) * 0.1¹⁰ * 0.9⁰ = 0.0000001

P(8 or more machines are functioning) = 0.1937 + 0.0386 + 0.0000001 = 0.2323

Hence, the probability that all printing requirements on a particular day will be met is 0.2323 or approximately 23.23%.

c. The interest that would accrue at Bank B is $201.82.

d. Kathy would owe $4776.82 at Bank B.

e. Kathy would save $1213.03 by using Bank B.

a. The annual interest at Bank A is 21.99%. The simple interest for 18 months can be calculated as:

I = Prt = 4500 x 0.2199 x (18/12) = $1484.32.

Therefore, the interest that would accrue at Bank A is $1484.32.

b. The total amount that Kathy would owe at Bank A is the sum of the principal and interest:

Total = Principal + Interest = $4500 + $1484.32. = $5984.32.

Therefore, Kathy would owe $5984.32 at Bank A.

c. The annual interest rate at Bank B is 2.99%, but there is also a one-time service fee of $75. The interest for 18 months can be calculated as:

I = Prt = 4500 x 0.0299 x (18/12) = $201.82.

Therefore, the interest that would accrue at Bank B is $201.82.

d. The total amount that Kathy would owe at Bank B is the sum of the principal, interest, and service fee:

Total = Principal + Interest + Service fee = $4500 + $201.82 + $75 = $4776.82

Therefore, Kathy would owe $4776.82 at Bank B.

e. By using Bank B, Kathy would save the difference between the total amount owed at Bank A and the total amount owed at Bank B:

Savings = Total at Bank A - Total at Bank B = $5989.85 - $4776.82 = $1213.03.

The standard deviation of this sample of shopping time is equal to 50.

In order to calculate the standard deviation of this sample of shopping time, we would have to first determine the mean of the data set.

Mathematically, the mean for these data sets would be calculated by using this formula:

Mean = [F(x)]/n

For the total sum of data, we have:

F(x) = 42 + 27 + 22 + 37 + 32

F(x) = 132.1.

Mean = 160/5

Mean = 32

Now, we can calculate the standard deviation by using this formula:

Standard deviation, S = √(1/n × ∑(xi - u₁)²)

Standard deviation, S = √(1/5 × ∑(42 - 32)² + 1/5 × ∑(27 - 32)² + 1/6 × ∑(22 - 32)² + 1/5 × ∑(37 - 32)² + 1/5 × ∑(32 - 32)²
