What is the length of arc AB if the radius is 14

To calculate the balance, add the outstanding deposits to the ending balance and subtract the outstanding checks.

To calculate the balance, we need to start with the ending balance and make adjustments for outstanding deposits and outstanding checks. First, add the outstanding deposits to the ending balance: 59.75 + 175.46 = 235.21. Next, subtract the outstanding checks from the previous result: 235.21 - 231.69 = 3.52. Therefore, the balance is $3.52.

The approximate value of 'x' in the diagram is 31. 64

Using the formula, tan α = opposite side/ adjacent side

Opposite side = side opposite the angle

Adjacent = the other side

IF  α  = 36°

Opposite = 23

Adjacent = x

tan 36 = 0. 727

Substitute values into the formula

tan 36° = 23/ x

0.727 = 23/ x

Make 'x' subject by cross multiplying

x * 0. 727 = 23

x = 23/ 0. 727

x = 31. 64

Thus, the approximate value of 'x' in the diagram is 31. 64

The original bill amount that Isabella owed before the late fee was $19,500.

We need to understand the relationship between the late fee and the original bill amount.

Isabella was charged a late fee of 4% of the original bill amount, and this late fee was $780.

Let's use the variable x to represent the original bill amount. Since the late fee is 4% of the original bill, we can write the equation:

[tex]0.04x = 780[/tex]

To find x, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.04:

[tex]x = \frac{780}{0.04}[/tex]

Now, we can calculate this value:

[tex]x = 19500[/tex]

Answer:

Option A. 6%

Step-by-step explanation:

250 tickets are sold at a fund raiser.

Sarah buys 15 tickets.

The probability that she will win the prize quilt = [tex]\frac{15}{250}[/tex]

                                                                              = 0.06 = 6%

The probability that Sarah will win is 6%.

To estimate the probability of getting fewer than 4 successes in a binomial distribution, we can use the normal distribution as an approximation based on the conditions np > 5 and nq > 5. By calculating the mean and standard deviation of the normal distribution, we can use a z-score to find the estimated probability. In this case, the estimated probability is approximately 0.1709.

The given question requires us to estimate the probability of getting fewer than 4 successes in a binomial distribution. To determine if we can use the normal distribution as an approximation, we need to check if both np and nq are greater than 5. In this case, np = 13 * 0.4 = 5.2 and nq = 13 * 0.6 = 7.8, so both conditions are satisfied. Thus, we can use the normal distribution as an approximation. Let's estimate P(fewer than 4) using the normal distribution.

The mean of the normal distribution is given by μ = np = 13 * 0.4 = 5.2. The standard deviation is calculated using the formula σ = √(npq), where q = 1 - p. So, q = 1 - 0.4 = 0.6. Plugging in the values, we get σ ≈ √(13 * 0.4 * 0.6) ≈ 1.789. Now, we can use the normal distribution to estimate the probability.

Using the z-score formula z = (x - μ) / σ, where x is the number of successes we want to estimate the probability for, we can find the z-score for 3.5 (less than 4). z = (3.5 - 5.2) / 1.789 ≈ -0.951. Now, we can use a standard normal distribution table or calculator to find the cumulative probability for this z-score. P(fewer than 4) = P(z < -0.951) ≈ 0.1709 (approximately). Therefore, the estimated probability of getting fewer than 4 successes in the given binomial distribution is approximately 0.1709.

Firstly, we would have to evaluate whether a normal approximation would be useful to use. However, given our conditions where `n` is 13, `p` is 0.4, `q` (the complement of `p`) is 1 - 0.4 or 0.6, we can clearly use the normal approximation to the binomial distribution because both `np` (13 * 0.4 = 5.2) and `nq` (13 * 0.6 = 7.8) are greater than 5.

For the normal approximation, we begin by calculating the mean (µ) and standard deviation (σ) of the binomial distribution. The mean of a binomial distribution is calculated as `np` hence in our case, `np` is 13 * 0.4 which is equal to 5.2. To find the standard deviation, we use the formula `sqrt(npq)`, so in our case, we have`sqrt(13 * 0.4 * 0.6)`, which is approximately 1.76635.

Now, to find the probability of getting fewer than 4, we would calculate a z-score for the value of x = 4. This helps convert the raw scores in a dataset into a standardised form, allowing us to better understand the position of individual scores in relation to the rest of the dataset. The z-score is calculated as `z = (x - µ) / σ` . With x being 4, µ is 5.2, and σ is 1.76635, our z-score will be (4 - 5.2) / 1.76635, which gives us approximately -0.67937.

Now, the last step is to find the cumulative probability associated with this z-score. In essence, the cumulative probability associated with a z-score tells you the probability that a certain observation will occur given a standard normal distribution (which is our case, as we've standardised our dataset using the z-score). Checking a z-table, or by using the cumulative distribution function for a value of z = -0.67937, the associated probability is approximately 0.24845.
So the final probability that we will get fewer than 4 is approximately 0.24845 or 24.85% when we use the normal distribution as an approximation to the binomial distribution.

Step-by-step explanation:

correct answer

The slope of the line passing through points J (0,0) and K (-2,8) is calculated using the slope formula and results in a slope of -4.

The question asks to calculate the slope of the line passing through points J (0,0) and K (-2,8). The slope of a line is found by the formula

slope = (y'' - y') / (x'' - x'), where (x', y') and (x'', y'') are the coordinates of two distinct points on the line. Substituting the given points into this formula gives us

slope = (8 - 0) / (-2 - 0) = 8 / -2 = -4.

The expression  -10 × X × 5 when X = -1 is equal to 50.

To evaluate -10 × X × 5 when X = -1, we substitute -1 for X in the expression:
