Imagine that a survey of randomly selected people finds that people who used sunscreen were more likely to have been sunburned in the past year.

There are several possible explanations for the finding that people who used sunscreen were more likely to have been sunburned in the past year.

However, without additional context or data, it is difficult to determine the most likely explanation definitively. Here are a few possible explanations to consider:

1. Ineffective or improper use of sunscreen: It is possible that the individuals who reported using sunscreen did not apply it correctly or did not reapply it as recommended.

Inadequate application or failure to follow proper sunscreen usage guidelines could result in insufficient protection from the sun's harmful rays, leading to sunburn.

2. Self-selection bias: It is possible that individuals who have previously experienced sunburns may be more likely to use sunscreen. They may be more aware of the potential risks and take precautions, including using sunscreen.

This could create an association between sunscreen use and sunburn, even though sunscreen itself is intended to prevent sunburn.

3. Recall bias: The survey responses may be subject to recall bias, where individuals may inaccurately remember or report their sunscreen use and sunburn experiences.

Memory limitations or subjective perceptions of sunburn severity could influence the reported data and the observed association between sunscreen use and sunburn.

4. Confounding factors: There may be other factors or variables at play that are related to both sunscreen use and sunburn. For example, individuals who engage in activities that increase sun exposure or who have certain skin types may be more likely to both use sunscreen and experience sunburn.

It is important to note that further investigation, including more detailed surveys, data collection and statistical analysis, would be necessary to determine the most likely explanation for the observed association between sunscreen use and sunburn.

A quadratic functiοn f whose zeroes are 2 and 5 is f(x) = x² - 7x + 10.

A quadratic functiοn is a secοnd-degree pοlynοmial functiοn οf the fοrm:

f(x) = ax² + bx + c

where a, b, and c are cοnstants, and a is nοt equal tο 0. The graph οf a quadratic functiοn is a parabοla, which can οpen upwards οr dοwnwards depending οn the sign οf the leading cοefficient a.

The term ax² is the quadratic term, bx is the linear term, and c is the cοnstant term. The cοefficient a determines the shape οf the parabοla, while the cοnstants b and c determine its pοsitiοn and οrientatiοn.

Quadratic functiοns can have οne, twο, οr zerο real rοοts (alsο knοwn as sοlutiοns οr zerοs), which cοrrespοnd tο the x-intercepts οf the parabοla. The number and nature οf the rοοts depend οn the value οf the discriminant, which is given by b² - 4ac.

If the zeroes are x = 2 and x  = 5 then the solutions must be:

(x - 2)(x - 5)

Multiply them and make a quadratic function

⇒ (x - 2)(x - 5)

⇒ (x²  - 5x)- (2x - 5)

⇒ x² -5x - 2x + 5

⇒ x² -5x - 2x + 5

⇒ x² - 7x + 5

Comparing this to the form of the quadratic function f(x) = ax² + bx + c, we see that a = 1, b = -7, and c = 10. Therefore, the quadratic function with zeros at 2 and 5 is:

f(x) = x²- 7x + 10

So, the correct option is f(x) = x² - 7x + 10.

The probability of drawing a yellow marble, holding on to it, and then drawing a red marble is approximately 0.1667 or 16.67%.

To find the probability of drawing a yellow marble, holding on to it, and then drawing a red marble, we need to calculate the probability of each event occurring and then multiply the probabilities together, since the events are dependent.

First, let's find the probability of drawing a yellow marble. There are 5 + 1 + 8 + 2 = 16 marbles in total, and 8 of them are yellow. Therefore, the probability of drawing a yellow marble is:

P(Yellow) = 8/16 = 1/2

Next, we need to find the probability of drawing a red marble after drawing a yellow marble and holding on to it. After drawing a yellow marble, there are 15 marbles left in the bag, and 5 of them are red. Therefore, the probability of drawing a red marble after drawing a yellow marble and holding on to it is:

P(Red|Yellow) = 5/15 = 1/3

Finally, we can find the probability of both events occurring by multiplying the probabilities together:

P(Yellow and Red) = P(Yellow) x P(Red|Yellow)

P(Yellow and Red) = (1/2) x (1/3) = 1/6

Therefore, the probability of drawing a yellow marble, holding on to it, and then drawing a red marble is 1/6, or approximately 0.167.

Answer : 21

We are given the expression

3(4f - 1) where f = 2

Firstly, we need to open the parenthesis

3 x4f - 3 x 1

= 12f - 3

Since, f= 2

Substitute the value of f = 2 into the above expression

= 12(2) - 3

= 24 - 3

= 21

The answer is 21

To determine the height of the building, we can use trigonometry. In this case, we can use the tangent function, which relates the angle of elevation to the height and shadow of the object.

The tangent of an angle is equal to the ratio of the opposite side to the adjacent side. In this scenario:

tan(angle of elevation) = height of building / shadow length

We are given the angle of elevation (43 degrees) and the length of the shadow (20 feet). Let's substitute these values into the equation:

tan(43 degrees) = height of building / 20 feet

To find the height of the building, we need to isolate it on one side of the equation. We can do this by multiplying both sides of the equation by 20 feet:

20 feet * tan(43 degrees) = height of building

Now we can calculate the height of the building using a calculator:

Height of building = 20 feet * tan(43 degrees) ≈ 20 feet * 0.9205 ≈ 18.41 feet

Therefore, the height of the building that casts a 20-foot shadow with an angle of elevation of 43 degrees is approximately 18.41 feet.

There are 30 women present Let's call the proportion of women present "x." If there are x + 5 more males than women, then there are x + 5 men present.

The total number of attendees is 65, thus we can create the following equation:

x + (x + 5) = 65

Expanding and figuring out x

2x + 5 = 65

2x = 60

2x = 60

x = 30

Thus, there are 30 women present and 30 + 5 = 35 males present.

Step-by-step explanation:

speed=d÷t.

s=1/4=1/20

cross multiply your equation

The linear equation is:

T(t) = -10°C + t*7.5°C

And the graph can be seen below.

Here we know that the oven heats the pizza at a rate of 7.5°C per minute.

And we know that after 12 minutes, the temperature of the pizza is 80°C.

Then if T is the initial temperature (when we put the pizza on the oven) we will have the relation:

80°C = T + 12*7.5°C

With that equation we can find the initial temperature:

80°C - 12*7.5°C = T = -10°C

So the initial temperature of the pizza is -10°C, then the relation is:

T(t) = -10°C + t*7.5°C

Where t is the time in minutes.

From the question, the sum of each of the geometric sequence are;

1)  31 3/4

2) 340

3) 11/16

4) -6, 12, -24

We have that;

Sn = a(1 -\(r^n\))/1 - r

Sn = 16(1 \(- (1/2)^7\))1 - 1/2

Sn = 16(1 - 1/128)/1/2

Sn = 16(127/128) * 2

Sn = 31 3/4

2) Un = a\(r^n\) -1

256 = \(4(4)^n-1\)

64 =\(4^n-1\)

\(4^3 = 4^n-1\)

n = 4

Sn= \(4(4^4 - 1)\)/4 - 1

Sn = 340

3) Since we have a5 then n = 5

Sn = 1(1 - (\(-1/2)^5\))/1 -(-1/2)

Sn = 33/32 * 2/3

The pharmacist is left with 2100 ml(milliliter) of cough syrup.

According to the question,

Pharmacists have 3.6 L(liter) of cough syrup.

1 L = 1000 ml (Given)

Therefore, 3.6 L = 3.6 x 1000

                           = 3600 ml

It’s given in the question that the pharmacist fills a 1500 ml bottle with cough syrup.

To find the quantity of cough syrup left with the pharmacist, we will subtract the quantity of bottle from the total quantity of cough syrup.

Cough syrup left with her after filling the bottle = 3600 – 1500

                                                                              = 2100 ml

Hence, she is left with 2100 ml of cough syrup after filling up a bottle of 1500 ml quantity.

An example of a function which is differentiable function on the real line r with exactly two roots but its derivative having 5 roots is\(f(x) = (x+2)(x-3)^2\)

The given information implies that the function f(x) has two x-intercepts and the derivative of f(x), denoted as f'(x), has five x-intercepts. Therefore, the graph of f(x) must have two local extrema (one minimum and one maximum) and the graph of f'(x) must have three local extrema (two minima and one maximum).

To construct an example of such a function, consider the following:

\(f(x) = (x+2)(x-3)^2\)

The function f(x) has two roots at x = -2 and x = 3, and its derivative is:

\(f'(x) = 3(x-3)^2 + 2(x-3)(x+2)\)

Simplifying f'(x), we get:

\(f'(x) = 5(x-3)^2 - 4(x-3)(x+2)\)

The derivative f'(x) has roots at x = -2, x = 1, x = 3, x = 5, and x = 9, implying that f(x) has local extrema at x = 1 and x = 5.

Thus, this example function satisfies the given conditions.
