how can you be able to find an area

Answer:

2

Step-by-step explanation:

The greatest common factor of whole numbers is the largest number that is a factor of all numbers. That is, it is the largest number that can divide all numbers.

In this case, the largest number that divide all the numbers is 2, who can divide 4, 18 and 12.

So:

[tex](4k, 18k^{4} ,12)= 2(2k,9k^{4} , 6)[/tex]

The answer is 140, you just add them up and it goes by 2.

Step-by-step explanation:

15 divided by 1.75 equals 9.

And in order to double check, we multiply 9 and 1.75 together which equals 15.75.

The probability Bill hits a higher percentage than Wilt in free throws is approximately 0.0085, or 0.85%.

To find the probability that Bill hits a higher percentage of his shots than Wilt, we can use the concept of binomial distributions.

Let's denote:

- [tex]\( W \)[/tex] as the number of successful shots Wilt makes out of 50,

- [tex]\( B \)[/tex] as the number of successful shots Bill makes out of 50.

Since Wilt makes 75% of his free throws and Bill makes 85% of his free throws, we can calculate the expected number of successful shots for each:

- For Wilt: [tex]\( E(W) = 50 \times 0.75 = 37.5 \)[/tex]

- For Bill: [tex]\( E(B) = 50 \times 0.85 = 42.5 \)[/tex]

Now, we can use the normal approximation to the binomial distribution to calculate the probability that Bill hits a higher percentage of his shots than Wilt. We'll assume that both distributions are approximately normal due to the central limit theorem.

The standard deviation for each player's distribution can be calculated as:

- For Wilt: [tex]\( \sigma_W = \sqrt{n \times p_W \times (1-p_W)} = \sqrt{50 \times 0.75 \times 0.25} \)[/tex]

- For Bill: [tex]\( \sigma_B = \sqrt{n \times p_B \times (1-p_B)} = \sqrt{50 \times 0.85 \times 0.15} \)[/tex]

Now, we can calculate the probability using a normal distribution:

[tex]\[ P(B > W) = P\left(Z > \frac{{E(B) - E(W)}}{{\sqrt{\sigma_B^2 + \sigma_W^2}}}\right) \][/tex]

Where [tex]\( Z \)[/tex] is a standard normal random variable.

Calculating:

[tex]\[ P(B > W) = P\left(Z > \frac{{42.5 - 37.5}}{{\sqrt{50 \times 0.85 \times 0.15 + 50 \times 0.75 \times 0.25}}}\right) \][/tex]

[tex]\[ P(B > W) = P(Z > 2.3717) \][/tex]

Using a standard normal distribution table or calculator, we find that  [tex]P(Z > 2.3717) \approx 0.0085 \).[/tex]

So, the probability that Bill hits a higher percentage of his shots than Wilt is approximately 0.0085, or 0.85%.

Using the simple interest formula I = PRT, it is calculated that Akule borrowed $1500 at an annual interest rate of 12% for 1.5 years to pay $270 in interest.

The subject of this question is Mathematics, specifically focusing on simple interest calculation. To find out the period of time Akule borrowed money for, we can use the simple interest formula I = PRT, where I is the interest paid, P is the principal amount borrowed, R is the annual interest rate, and T is the time in years. Akule paid $270 in interest on a $1500 loan at 12% annual simple interest. Using the formula, we solve for T as follows:

T = I / (P × R)

T = $270 / ($1500 × 0.12)

T = $270 / $180

T = 1.5 years

Therefore, Akule borrowed the money for 1.5 years.

Akule borrowed the money for 0.18 years.

To find the period of time Akule borrowed the money, we can use the formula:

Interest = Principal × Rate × Time

Given that Akule paid $270 in interest and borrowed $1500 at an annual simple interest rate of 12%, we can plug in these values into the formula:

270 = 1500 × 0.12 × Time

Simplifying the equation, we get:

0.12 × Time = 270 / 1500

Time = (270 / 1500) / 0.12

Time = 0.18 years

Hence, Akule borrowed the money for 0.18 years.

The equation of the line with a slope of 2 passing through the point (3, 9) is y = 2x + 3.

The equation of a line with slope (m) passing through a point (x₁, y₁) is given by the point-slope form:

y - y₁ = m(x - x₁)

The slope (m) is 2, and the point (x₁, y₁) is (3, 9). Plug these values into the equation:

y - 9 = 2(x - 3)

Now, you can simplify this equation:

y - 9 = 2x - 6

To isolate y, add 9 to both sides:

y = 2x - 6 + 9

y = 2x + 3

Therefore, the equation of the line with a slope of 2 passing through the point (3, 9) is y = 2x + 3.

Answer: [tex][Q - R] + [S - T]=10m+7n-14[/tex]

Step-by-step explanation:

[tex]R = 11 -2m[/tex],

[tex]S = n + 5[/tex], and

[tex]T = -m - 3n + 8[/tex]

Now  , [tex]Q-R= 7m + 3n-(11 - 2m)[/tex]

[tex]Q-R= 7m +3n-11+2m[/tex]    [ ∵ (-)(+)=(-) and (-)(-)=(+)]

[Note : when -1 is outside the parenthesis it indicates that -1 should be multiplied with each of the terms present inside the parenthesis .]

[tex]Q-R= 9m +3n-11[/tex]  [Combine like terms.]

[tex]S-T=n + 5-(-m - 3n + 8)[/tex]

[tex]S-T=n + 5+m+3n-8[/tex]    [ ∵ (-)(+)=(-) and (-)(-)=(+)]

Answer:

Let the probability of error-free transmission of a message over a communication channel is P.

Then the Probability of Retransmission  is =1-P

Now the question is Probability when no retransmission is required

                            = Probability of error free transmission in first attempt

                               =P

Now , suppose after first failure error free transmission takes place.

Since events are independent.

∵P[error free transmission after a failure ]= P[1-P]

If after two attempts error free transmission takes place

then P[ error free transmission after two failures]= P [1-P]²

So, For after n failures

P[error free transmission after n failure]=P[tex][1-p]^n[/tex]

Answer:

60 marbles

Step-by-step explanation:

Given:  24 red marbles is 40% of how many marbles

Let number of marbles be x

"24 red marbles is 40% of how many marbles"

             24 = 40% of x

solve for x

First change % to decimal

    24 = 0.40x

Division property of equality, divide by 0.04 both sides

     x = 24÷0.40

     x = 60

Hence, 40% of 60 is 24

To determine equations with no real solutions, assess for a negative discriminant or no x-intercepts in quadratic equations. Steps include identifying unknowns, choosing appropriate equations, simplifying terms, and checking for reasonableness.

To select each equation that has NO real solution, we must assess the equations provided, looking for specific characteristics that indicate the absence of real solutions. One of the hallmarks of such equations is when they represent a quadratic equation with no x-intercepts or the discriminant (b^2 - 4ac) in the quadratic formula is negative, which means the roots are complex numbers.

When working on problems like these, it's crucial to go through several steps: Identify the unknown, identify the knowns, choose an equation, eliminate terms to simplify the algebra, and then check the answer to see if it is reasonable.

Let's use an example equation: x^2 + 4 = 0. To determine if this has real solutions, we can identify the unknown (x), the knowns (coefficients of x), solve the equation or calculate the discriminant (4^2 - 4*1*-4 = 16 +16 = 32, which is positive), and confirm whether the solutions are real or not. In this case, because the discriminant is positive, this equation does have real solutions, and therefore would not be included in a list of equations with no real solutions.

The equations 2x² - 4x + 5 = -3, x² - 12x + 60 = 12, and x² + 3x + 6 = 0 have no real solutions, based on their negative discriminants.

We need to determine the discriminant (b² - 4ac) of each equation to check for real solutions. A negative discriminant indicates no real solutions.
