Whats 2 + 6? If the 2 is really a 7?

Answer: 134 tickets.

Step-by-step explanation:

Since we have 14 packs of 9 tickets, we can say it is 14 groups of 9. Which means we multiply. So 9 times 14 equals 126. But Ivan found 8 more tickets on the groud which means we add. so 126 plus 8 equals 134. The answer is 134 tickets.

Answer:

Step-by-step explanation:

multiply # of packs by # of tickets in each pack then add 8

14 x 9 = 126 + 8 = 134

The area under the standard normal distribution curve between z = 1 and z = 1.73 is 0.1169 (rounded to three decimal places).

To find the area under the standard normal distribution curve between the z-scores of 1 and 1.73, we need to calculate the cumulative probability or area under the curve.

Using a standard normal distribution table or a calculator, we can find the corresponding probabilities for each z-score.

For z = 1:

The cumulative probability or area to the left of z = 1 is approximately 0.8413.

For z = 1.73:

The cumulative probability or area to the left of z = 1.73 is approximately 0.9582.

To find the area between the two z-scores, we subtract the cumulative probability of the lower z-score from the cumulative probability of the higher z-score.

Area = 0.9582 - 0.8413 = 0.1169

Therefore, the area under the standard normal distribution curve between z = 1 and z = 1.73 is 0.1169 (rounded to three decimal places).

Answer: x = 16

Step-by-step explanation:

Supplementary means when the two angles are added together they equal 180 degrees.

(6x+8) + (4x+12) = 180

10x + 20 = 180

10x = 160

X = 16

Answer:

1. True

2. HGK

3. 17⁰

Step-by-step explanation:

1. All angles in a triangle need to add up to 180. The right angle is a given 90⁰ so the other two angles need to add up to 90⁰ to equal 180⁰. Angle C corresponds to Angle K so Angle H corresponds to Angle E. So add Angle C and H together and it sums up to 90⁰ so it is true.

2. HGK; you match it up with the markings inside the triangle

3. Same logic with number 1 but you subtract 90 from 73 to find Angle K.

Answer:

The material cost for December = $356,000

Step-by-step explanation:

The manufacturing overhead is the sum of the indirect costs that come from the manufacturing process except labor and materials

Hence, whereby the cost per liter = $0.47, we have;

Total volume produced = 4.0 million liters

Manufacturing overhead = $1,435,000

Total cost = Cost per liter × Total volume produced

∴ Total cost = 4 × 10⁶ × $0.47 = $1,880,000

Hence the cost of labor + materials = Total cost - Manufacturing overhead

the cost of labor + materials = $1,880,000 - $1,435,000 = $445,000

Labor cost = 25% material cost = 0.25 × material cost

∴ 0.25 × material cost + material cost = $445,000

1.25 × material cost = $445,000

material cost = $445,000/1.25 = $356,000

Which gives labor cost = 0.25 × $356,000 = $89,000

The material cost for December = $356,000.

The hypotheses for the test are H₀: σ₁² = σ₂² and H₁: σ₁² ≠ σ₂². This is a two-tailed test to assess if there is a difference in the standard deviations of sound levels between the areas designated as "casualty doors" and operating theaters. The claim being investigated is whether or not there is a difference in the standard deviations.

The hypotheses for the test are:

H₀: σ₁² = σ₂² (There is no difference in the standard deviations of the sound levels between the areas designated as "casualty doors" and operating theaters.)

H₁: σ₁² ≠ σ₂² (There is a difference in the standard deviations of the sound levels between the areas designated as "casualty doors" and operating theaters.)

This hypothesis test is a two-tailed test because the alternative hypothesis is not specifying a direction of difference.

To substantiate the claim that there is a difference in the standard deviations, we will conduct a two-sample F-test at a significance level of 0.10, comparing the variances of the two groups.

The probability that the student makes it to the second class before it starts is very close to 0.

To find the probability that the student makes it to the second class before it starts, we can use the concept of linear combinations of random variables and the properties of normal distributions.

Let's define the random variable X as the total time it takes for the student to transition from the end of the first class to the start of the second class. Since X is a linear combination of independent normally distributed random variables (X1, X2, X3), we can use their means and variances to calculate the mean and variance of X.

The mean of X is the sum of the means of X1, X2, and X3:

μX = μ1 + μ2 + μ3 = 9:02 + 9:15 + 10 = 28:17 minutes.

The variance of X is the sum of the variances of X1, X2, and X3:

σX^2 = σ1^2 + σ2^2 + σ3^2 = (2.5)^2 + (3)^2 + (2.5)^2 = 15.25 minutes^2.

Now, we need to calculate the probability that X is less than or equal to 0, meaning the student arrives before the second lecture starts. Since X follows a normal distribution, we can standardize the variable and calculate the probability using the standard normal distribution table.

Z = (0 - μX) / σX = (0 - 28:17) / √15.25 ≈ -9.43.

Using the standard normal distribution table or a calculator, we can find the probability corresponding to Z = -9.43. The probability is essentially 0, as the value is significantly far in the left tail of the standard normal distribution.

Therefore, the probability that the student makes it to the second class before it starts is very close to 0.

According to given,

p = 0.12 (success)

q = 1 - 0.12

  = 0.88 (failure)

x = 7

By applying binomial probability distribution we get -

P(x) = nCx.p^x.q^(n-x)

⇒ P(x=7) = nC7.(0.12)^7.(0.88)^(n-7)

Also given,

Probability of 7 successful trials = 0.77

Thus,

nC7.(0.12)^7.(0.88)^(n-7) = 0.77

⇒ n!/(7! (n-7)!).(0.12)^7.(0.88)^(n-7) = 0.77

⇒ n!/(7! (n-7)!).(0.88)^n = 0.77 * (0.88/0.12)^7

⇒ n!/(7! (n-7)!).(0.88)^n = 878214.711

⇒ n = 130

Thus, the number of calls needed to ensure that there is a probability of at least 0.77 of obtaining 7 or more successful calls is 130.

Thus, the p-value is greater than 0.10 (the significance level α), indicating that there is not enough evidence to support the alternative hypothesis.

To find the p-value, we need to calculate the test statistic and compare it to the critical value.

Given:

Sample 1: sample size (n1) = 22, variance (\(s_{1}^2\))

= 8, mean (x1(bar))

= 51

Sample 2: sample size (n2) = 20, variance (\(s_{2}^2)\)

= 11, mean (x2(bar))

= 50.5

To calculate the test statistic, we can use the formula for the difference in means:

t = (x1(bar) - x2(bar)) / √((\(s_{1}^2\)/n1) + (\(s_{2}^2\)/n2))

Substituting the given values:

t = (51 - 50.5) / √((8/22) + (11/20))

  = 0.5 / √(0.3636 + 0.55)

  = 0.5 / √0.9136

  ≈ 0.53

Now we need to find the degrees of freedom. For independent samples with equal variance, the degrees of freedom (df) can be calculated using the formula:

df = n1 + n2 - 2

Substituting the given values:

df = 22 + 20 - 2

  = 40

With α = 0.10, the critical value for a one-tailed test (upper tail) with 40 degrees of freedom is 1.684.

Now, we can determine the p-value. Since the alternative hypothesis is μ1 - μ2 > 0, we are conducting an upper-tailed test.

The p-value is the probability of obtaining a test statistic as extreme as the one observed (t = 0.53) under the null hypothesis.

By comparing the test statistic to the critical value, we can determine the conclusion:

Since the test statistic (0.53) is less than the critical value (1.684), we fail to reject the null hypothesis.

Therefore, the conclusion is: "We don't have enough evidence to conclude that the difference in means is > 0; therefore, H0 is not rejected."

Answer:

The remainder will be 3.

Step-by-step explanation:

We can use the Polynomial Remainder Theorem. According to the PRT, if we have a polynomial P(x) divided by a binomial in the form (x - a), then the remainder will be given by P(a).

Our polynomial P(x) is given by the graph, and we are dividing it by the binomial (x + 1).

We can rewrite the binomial as (x - (-1)).

Therefore, a = -1.

Then the remainder will be P(-1).

Looking at the graph, we can see that P(-1) = 3.

Thus, the remainder when P(x) is divided by (x + 1) is 3.

On comparison of the dotted red line with the solid blue line, it is apparent that the x-coordinates do not change, yet the y-coordinates are negatives of each other.

This suggests a reflection in the x-axis.

(Note: If the function was reflected in the y-axis, the y-coordinates would not change, yet the x-coordinates would be negatives of each other).

Mapping rule for reflection in the x-axis:
