what is the probability that a randomly selected adult american uses social media, given the individual is 18–34 years of age?

Answer:

D. He answers the same number of questions correctly in both rounds and the same number of questions incorrectly in both rounds​.

Step-by-step explanation:

In the first equation he earns 5 points and loses 3 points. The value of one question is 5 points, and the value of losing one question is 3 points. The same goes for the second equation except the fact that its 10 points and 4 points lost instead.

According to the given measurement, the total amount of intake is 621.0435 ml

Here we have given the following measurements they are listed as follows:

=> 1/2 cup of orange juice,

=> 2/3 glass of milk, full cup of lemonade,

=> full glass of water,

=> 1 popsicle (3 ounces) and

=> 4 ounces ice chips.

Here we also know that

1 cup = 8 oz

1 glass = 6 oz

And as per the Si measurements,

1 oz = 29.5735 ml.

To order to calculate the total amount of intake we have to sum all the given measurements, then we get,

=> 1/2(8) + 2/3(6) + 6 + 3 + 4

When we simplify this one then we get,

=> 4 + 4 + 6 + 3 + 4 = 21

Now, we have to convert ounce into milliliter, for that we have multiply 29.5735 with the total measurement, then we get,

=> 21 x 29.5735 = 621.0435 ml

Explicit rule used is: f(n) = f(1) + (n - 1)d

Step-by-step explanation:

We are told he currently does 14 push ups per day.

Now, he wants to increase the push ups by 2 per day.

Now, the first term in the sequence of push ups is 14 while the constant difference is 2.

Now, the explicit rule to be used here is arithmetic progression whereby;

f(n) = f(1) + (n - 1)d

Where;

f(1) is first number in the sequence

d is constant difference

n is number of days

Thus, plugging in our values from the question, we have;

f(n) = 14 + (n - 1)2

f(n) = 14 + 2n - 2

f(n) = 2n + 12

This tallies with the linear function given in the question.

Thus; the explicit rule used here is;

f(n) = f(1) + (n - 1)d

Answer:

The population of the town of 2020 is approximately 6847

Step-by-step explanation:

The given population of the small town is 2002, P₀ = 10,800

The annual percentage decrease in the population, r = 2.5%

The date at which the new population,'P', is required = 2020

Therefore;

The number of years over which the population changes, 't', is given as follows;

t = 2020 - 2002 = 18

The number of years over which the population changes, t = 18 years

Given that the population is decreasing, we get;

The general formula for exponential decay is given as follows;

\(P = P_0 \cdot (1 - r)^t\)

Therefore, the population, 'P', of the town of 2020 which is in t = 18 years, is given as follows;

\(P = 10,800 \times(1 - 0.025)^{18} = 6847.10263915\)

Given that the population is given in whole numbers, we round down to the nearest whole number population of people as follows;

The population of the town of 2020, P ≈ 6847.

The function rule representing the situation is C = 5.77g, where C is the total cost and g is the weight of ham in grams.

The function rule C = 5.77g represents the relationship between the total cost (C) and the weight of ham (g) in grams. In this situation, each gram of ham costs $5.77, so the total cost is obtained by multiplying the cost per gram ($5.77) by the weight of ham (g).

The equation C = 5.77g follows a linear relationship, where the cost (C) is directly proportional to the weight of ham (g). This means that as the weight of ham increases, the total cost also increases proportionally. For example, if we have 100 grams of ham, the total cost would be calculated as 5.77 * 100 = $577.

By using this function rule, we can easily determine the total cost of any given weight of ham. It provides a straightforward way to calculate the cost without needing to perform complex calculations or look up individual prices for different quantities. This equation can be useful in various situations, such as meal planning, budgeting, or determining the cost for commercial purposes.

The x1 value you find will be the x-coordinate of the object "arrow."

The position of any point in three-dimensional space can be represented by three Cartesian coordinates, the distance from the point to the three coordinate planes. In general, n Cartesian coordinates represent points of an arbitrary n in n-dimensional Euclidean space. These coordinates are signed at the distance from the point to n fixed hyperplanes perpendicular to each other.

To find the x-coordinate (x1) of the object "arrow," follow these steps:

1. Identify the object "arrow" on your graph or diagram.
2. Locate the point where the object's base (or tip) touches the x-axis.
3. Read the x-coordinate (x1) value at this point.

The x1 value you find will be the x-coordinate of the object "arrow."

Answer: Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number's sign: if it's positive, it's equal to the number: |9|=9. If the number is negative, then the absolute value is its opposite: |-9|=9.

Step-by-step explanation:

This is because the F-statistic for omitting BDR and Age from the regression is 0.08, which is less than the critical value for the test using the F-distribution table.

To test if the coefficients on BDR and Age are statistically different from zero, we compare the F-statistic with the critical value from the F-distribution table. The F-statistic is a measure of the overall significance of the regression model when certain variables are omitted.

In this case, the F-statistic is given as 0.08. To determine if the coefficients are statistically different from zero at the 5% level, we compare this value with the critical value from the F-distribution table. The critical value represents the threshold beyond which we reject the null hypothesis.

Based on the statement provided, it states that 0.08 is "less than the critical value." Since the F-statistic is smaller than the critical value, we can conclude that the coefficients on BDR and Age are not jointly significant at the 5% level. In other words, we fail to reject the null hypothesis that the coefficients are equal to zero.

The use of the phrase "jointly significant" implies that the significance of the coefficients is considered together, rather than individually. The test assesses the overall impact of BDR and Age on the regression model, rather than their individual effects. Since the F-statistic falls below the critical value, we do not have sufficient evidence to conclude that BDR and Age have a significant impact on the model.

Step-by-step explanation:

Let ABC be an isosceles triangle with sides AC and BC of equal length.                

We need to prove that the medians AD and BE are of equal length.

Consider the triangles ADC and BEC.

They have two congruent sides that include congruent angles.

Indeed, AC = BC by the condition, because the triangle ABC is isosceles.

Since the lateral sides AC and BC are of equal length, their halves EC

and DC are of equal length too: EC = DC.

Finally, the angle ECD is the common angle.

Thus, the triangles ADC and BEC are congruent, in accordance to the

postulate P1 (SAS) (see the lesson Congruence tests for triangles of the

topic Triangles in the section Geometry in this site).

Hence, the medians AD and BE are of equal length as the corresponding sides

of these triangles.

The proof is completed.

The limit, if it exists, or show that the limit does not exist is to be found using the function Lim(x,y,z) → (0,0,0) xy+yz+xz / x²+y²+z².

The given function can be simplified as shown below: xy+yz+xz / x²+y²+z²= x(y+z)/x²+y²+z²+ y(x+z)/x²+y²+z²+ z(x+y)/x²+y²+z²

Now, we'll use the squeeze theorem to find the limit:

0 ≤ |x(y+z)/x²+y²+z²| ≤ |x|/√(x²+y²+z²) (since |y+z| ≤ |y|+|z| ≤ √(y²+z²+2yz))

Similarly, 0 ≤ |y(x+z)/x²+y²+z²| ≤ |y|/√(x²+y²+z²) and 0 ≤ |z(x+y)/x²+y²+z²| ≤ |z|/√(x²+y²+z²)

So, we have: 0 ≤ |xy+yz+xz|/x²+y²+z² ≤ (√(x²+y²+z²)/√(x²+y²+z²)) (|x|+|y|+|z|)0 ≤ |xy+yz+xz|/x²+y²+z² ≤ (|x|+|y|+|z|)

And now we'll apply the squeeze theorem.

Let L = lim(x,y,z) → (0,0,0) xy+yz+xz / x²+y²+z²

Thus,0 ≤ |xy+yz+xz|/x²+y²+z² ≤ (|x|+|y|+|z|) → 0 as (x,y,z) → (0,0,0)

Therefore, by squeeze theorem, lim(x,y,z) → (0,0,0) xy+yz+xz / x²+y²+z² = 0

Hence, the given limit exists and is equal to 0.

The total amount reported in the cash flows from investing activities section of the statement of cash flows would be a gain of $12,000.

The cash flows from investing activities section of the statement of cash flows captures the cash transactions related to the purchase or sale of long-term assets, such as property, plant, and equipment. When an office equipment is sold for cash, the cash received from the sale is recorded as an inflow in the investing activities section.

In this scenario, a gain of $12,000 is incurred from the sale of office equipment with a book value of $110,000. The gain represents the excess of the cash received from the sale over the book value of the equipment. Since the gain is considered a positive cash flow, it would be included as an inflow in the cash flows from investing activities section.

Therefore, the total amount reported in the cash flows from investing activities section would be the gain of $12,000, indicating a positive cash inflow resulting from the sale of the office equipment.

1. To find the volume of the zone 1 cone, you need to subtract the smaller cone from the larger cone. The larger cone can be visualized as an entire cone, and the smaller cone as a cone that has been cut off from the top.

2. Given the radii and heights of the cones are, r1 = 4, r2 = 2, h = 12To find the volume of the zone 1 cone, Volume of cone = 1/3πr1²h1/3 × 3.14 × 4² × 6= 100.48 cubic units We now need to find the volume of the smaller cone and then subtract it from the volume of the larger cone. The height of the smaller cone is 6 units and its radius is 2 units. So, the volume of the smaller cone = 1/3 π (2)² (6)1/3 × 3.14 × 4 × 2= 16.74 cubic units Now, the volume of zone 1 cone can be found by subtracting the volume of the smaller cone from the volume of the larger cone.= 100.48 – 16.74= 83.74 cubic units

3. To find the volume of the zone 2 cone, we just need to use the formula of the volume of the cone. Volume of cone = 1/3πr²h

4. Given the radii and heights of the cones are, r1 = 4, r2 = 2, h = 12To find the volume of the zone 2 cone, we first find the volume of the entire cone. Volume of cone = 1/3πr²h1/3 × 3.14 × 4² × 12= 201.06 cubic units Now we find the volume of the smaller cone (zone 1).Volume of smaller cone = 1/3 πr²h1/3 × 3.14 × 2² × 6= 16.74 cubic units The volume of the zone 2 cone can be found by subtracting the volume of the smaller cone from the volume of the larger cone.= 201.06 – 16.74= 184.32 cubic units

5. To find the number of mosquitoes in zone 2 than in zone 1, we need to use the ratio of the volumes of zone 2 cone and zone 1 cone. Volume of cone = 1/3πr²hNumber of mosquitoes ∝ Volume of cone Since the height is the same for both cones, we can use the ratio of the radii to find the ratio of their volumes. Ratio of volumes = (Volume of zone 2 cone)/(Volume of zone 1 cone)= 184.32/83.74= 2.2So, there are 2.2 times more mosquitoes in zone 2 than there are in zone 1.
