The partial pressure of O2 at the elevation of Mount Saint Elias (z = 5.489 km ASL) is 1.927 mb and the percentage of O2 at this height with respect to sea level O2 is 9%.

The partial pressure of oxygen (O2) at any given height can be calculated using the following formula:

Partial pressure of O2 at height = (percentage of O2 at height/100) × partial pressure of O2 at sea level

Given,

Sea level pressure = 1000 mb

Partial pressure of O2 at sea level = 0.21 × 1000 = 210 mb

1. For cruising altitude of a jet (z = 9.5 km ASL):

Using the 50% reduction rule, the sea level pressure at this height can be calculated as:

sea level pressure × (1 - 0.12 × z/1000) = 1000 × (1 - 0.12 × 9.5) = 820 mb

Now, the partial pressure of O2 at this height can be calculated as:

Partial pressure of O2 at height = (0.21 × 820)/100 = 1.722 mb

The percentage of O2 at this height with respect to the sea level O2 is given by:

Percentage of O2 at height = (1.722/210) × 100 = 8%

Therefore, the partial pressure of O2 at a cruising altitude of a jet (z = 9.5 km ASL) is 1.722 mb and the percentage of O2 at this height with respect to sea level O2 is 8%.

2. For the elevation of Mount Saint Elias (z = 5.489 km ASL):

Using the 50% reduction rule, the sea level pressure at this height can be calculated as:

sea level pressure × (1 - 0.12 × z/1000) = 1000 × (1 - 0.12 × 5.489) = 917 mb

Now, the partial pressure of O2 at this height can be calculated as:

Partial pressure of O2 at height = (0.21 × 917)/100 = 1.927 mb

The percentage of O2 at this height with respect to the sea level O2 is given by:

Percentage of O2 at height = (1.927/210) × 100 = 9%

approximately 23 child tickets were sold on Saturday at the movie theater.

To find the number of child tickets sold at the movie theater on Saturday, we can follow these steps:

1. Let's assume the number of child tickets sold is "x". Since the child admission is $5.60, the total revenue from child tickets would be 5.60x dollars.
2. Given that three times as many adult tickets were sold, the number of adult tickets sold would be 3x. Since the adult admission is $8.90, the total revenue from adult tickets would be 8.90 * 3x dollars, which can be simplified to 26.70x dollars.
3. The total sales for the day is given as $742.90. Therefore, the sum of the revenues from child and adult tickets should equal $742.90:
  5.60x + 26.70x = 742.90
4. Combining like terms, we get:
  32.30x = 742.90
5. To isolate x, the number of child tickets sold, we divide both sides of the equation by 32.30:
  x = 742.90 / 32.30
6. Evaluating the division, we find that x is approximately equal to 23.0078.
7. Since we can't sell a fraction of a ticket, we round down to the nearest whole number. Therefore, approximately 23 child tickets were sold on Saturday at the movie theater.

Answer:

a) two parallel lines

Step-by-step explanation:

Two parallel lines have the same slope

Let's take a concrete example:
y = 2x + 4        (slope =2, y-intercept = 4)
y = 2x + 10      (slope = 2, y-intercept = 10)

Lines are parallel to each other

If you try to solve this equation you get

2x + 4 = 2x + 10

Subtracting 2x on both sides gives you  the identity 4 = 10 (a contradiction)

This means the 2 line equations are inconsistent

The difference between the volume of the sphere and the volume of the cone is approximately 838.81 cubic inches.

The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius. Thus, for a sphere with a radius of 6 inches, the volume is:

V_sphere = (4/3)π(6³) = 904.78 cubic inches

The volume of a cone is given by the formula V = (1/3)πr\(^{2h}\), where r is the radius and h is the height. Thus, for a cone with a radius of 3 inches and a height of 7 inches, the volume is:

V_cone = (1/3)π(3²)(7) = 65.97 cubic inches

Therefore, the difference between the volume of the sphere and the volume of the cone is:

V_sphere - V_cone = 904.78 - 65.97 = 838.81 cubic inches

Hence, the difference between the volume of the sphere and the volume of the cone is approximately 838.81 cubic inches.

0.529 is the probability that a student does not have a college degree.

From the information given, we know that:

The formula for conditional probability:

P(A|B) = P(A and B) / P(B)

Let A be the event of not having a college degree, and B be the event of being married. We want to find P(A).

Using these values, we can calculate:

P(college degree and B) = (1/2) * (400/850) = 0.235

P(A and B) = 310/850 - 0.235 = 0.07

Finally, we can calculate P(A) using the formula for total probability:

P(A) = 1 - P(college degree)

= 1 - (400/850)

= 0.529

Therefore, the probability that a student does not have a college degree is 0.529.

The domain and the range of the radical function f(x) = √(x - 5) + 10 are x ≥ 5 and y ≥ 10, respectively.

In this problem we must determine the domain and range of a radical function of the form:

f(x) = √(a · x - b) + c

Where a, b, c are real coefficients.

The domain of the function is the set of x-values such that f(x) exists. The range is the set of values of f(x). Regarding the radical function, the expression have the following features:

a · x - b ≥ 0

a · x ≥ b

If a ≥ 0, then:

x ≥ b / a

But if a < 0, then:

x ≤ b / a

And range is every value of f(x) such that x ≥ b / a for a ≥ 0 or x ≤ b / a for a < 0. If we know that a = 1, b = 5 and c = 10, then the domain and range of the radical function:

Step-by-step explanation:

The 99% confidence interval for the true average lifetime of individuals suffering from blood cancer is (1102.85, 1280.35) days.

a) Yes, a confidence interval for the true average lifetime can be calculated without assuming anything about the nature of the lifetime distribution. This is because the given information states that a normal probability plot of the data exhibits a reasonably linear pattern. In such cases, the Central Limit Theorem can be applied, which allows us to estimate the population mean and construct a confidence interval even when the underlying distribution is unknown or non-normal.

b) To calculate a confidence interval with a 99% confidence level for the true average lifetime, we can use the sample mean (1191.6) and the sample standard deviation (506.6) provided. With the given sample size and assuming a normal distribution, we can use the t-distribution for constructing the interval.

Using the t-distribution with n-1 degrees of freedom (where n is the sample size), and considering the sample mean and standard deviation, the confidence interval can be calculated as follows:

CI = sample mean ± (t-value) * (sample standard deviation / sqrt(sample size))

Plugging in the values:

CI = 1191.6 ± (t-value) * (506.6 / sqrt(43))

To determine the t-value for a 99% confidence level with 43 degrees of freedom, we can consult the t-table or use statistical software. Assuming a two-tailed test, the t-value would be approximately 2.704.

Substituting the values:

CI = 1191.6 ± (2.704) * (506.6 / sqrt(43))

Calculating the interval:

CI = 1191.6 ± 88.75

Therefore, the 99% confidence interval for the true average lifetime is (1102.85, 1280.35).

Interpretation: We are 99% confident that the true average lifetime for individuals suffering from blood cancer falls within the range of 1102.85 to 1280.35 days.

Note: complementary angles are two angles whose sum is 90⁰

Answer:

52 degrees

Step-by-step explanation:

Complementary angles have a sum of 90. This means when added they will equal 90. So to solve had the 2 expressions and set them equal to 90.

This looks like, \((2x+18)+(6x-8)=90\). Then, isolate the variable and solve.

2x +18 +6x -8 =90

8x +10 =90

8x = 80

x=10

Finally, plug 10 in for x in the expression for angle b. This equals 52 degrees.
