Answer:

\(Probability = 0.068\)

Step-by-step explanation:

Let P(S) represent the probability that stock market will go up in a day

Given

\(P(S) = 51\%\)

Required

Determine the probability that stock will go up 4 consecutive days

Start by converting P(S) from percentage to decimal

\(P(S) = 51\%\)

\(P(S) = \frac{51}{100}\)

\(P(S) = 0.51\)

The above expression represents the probability in a day;

For 4 days; we have:

\(Probability = P(S) * P(S) * P(S) * P(S)\)

\(Probability = (P(S))^4\)

Substitute 0.51 for P(S)

\(Probability = (0.51)^4\)

\(Probability = 0.06765201\)

\(Probability = 0.068\) -- Approximated

Hence, the probability that stock will rise for 4 consecutive days is 0.068

By using the definition of supplementary angles and the fact that the sum of the interior angles of a triangle always gives 180°, we will see that X° = 136°.

First, notice that we have two isosceles triangles. By looking at the top angle, we can see that the interior angle of the top triangle and the angle of 101° are supplementary, then the measure of that angle is:

M = 180°  -101° = 79°

Remember that the sum of the interior angles of a triangle is always equal to 180°, then for the top triangle we can write:

a + 79° + 79° = 180°

a = 180° - 2*79° = 22°

Where a si the angle of the bottom vertex, where the two triangles intersect.

Then the top angle of the bottom triangle also measures 22°.

Now, the two angles of the base of the bottom triangle measure 22°, and using again that the sum of the interior angles must give 180°, we will get:

22° + 22° + x° = 180°

x° = 180° - 2*22° = 136°

In this way, we conclude that the measure of angle X° is 136°.

The Answer:

Width = 6

Step-by-step explanation:

Let width be w

(w + 8 x 6) (w-6) = 0

w = 6

The value of the "trigonometric-expressions' are :

(a) tan(5π/2) is undefined,

(b) sec(315°) is √2.

Part(a) : The expression "tan(5π/2)" is undefined because the tangent function is undefined at odd multiples of π/2, which includes 5π/2.

Part(b) : To find the value of sec(315°), we use the identity: sec(θ) = 1/cos(θ),

First, we convert 315° to radians:

Which is : 315° = (7π/4) radians;

Next, we find the value of cos(7π/4):

⇒ cos(7π/4) = cos(π/4) = (√2)/2;

Finally, we substitute in the identity for sec(θ);

So, Sec(7π/4) = 1/cos(7π/4) = 1/[(√2)/2] = √2.

Therefore, value of sec(315°) is √2.

The appropriate hypotheses for this test are: H0: There is no difference in the distribution of responses. Ha: There is a difference in the distribution of responses.

The chosen hypotheses are based on the objective of the investigation, which is to determine if there is convincing evidence that the distribution of responses about eating the potato salad differs between employees who are sick and those who are not sick.

The null hypothesis (H0) assumes that there is no difference in the distribution of responses about eating the potato salad between the sick and non-sick employees. This means that the proportion of employees who ate the potato salad would be the same in both groups, and any observed difference in the distribution of responses is due to random chance or factors unrelated to being sick or not sick.

On the other hand, the alternative hypothesis (Ha) proposes that there is a difference in the distribution of responses about eating the potato salad between the sick and non-sick employees. This suggests that the proportion of employees who ate the potato salad would be significantly different in the two groups, indicating a possible association between consuming the potato salad and getting sick.

By formulating these hypotheses, the investigation aims to evaluate whether the data provides convincing evidence to reject the null hypothesis in favor of the alternative hypothesis, indicating a meaningful relationship between eating the potato salad and falling sick.

Therefore, the correct answer is:

H0: There is no difference in the distribution of responses about eating the potato salad among those who are and are not sick.

Ha: There is a difference in the distribution of responses about eating the potato salad among those who are and are not sick.

Step-by-step explanation:

An exponential equation in the form \(y=a(b)^x\) that can model the amount of caffeine, y, in Kendall's body x hours after drinking the coffee is

The amount of caffeine that will be in Kendall's body after 12 hours is 18 milligrams.

In Mathematics, an exponential function can be modeled by using the following mathematical equation:

f(x) = a(b)^x

Where:

Since Kendall drank a cup of coffee that had 95 milligrams of caffeine which is decreasing at a rate of 5% per day, this ultimately implies that the relationship is geometric and the rate of change (decay rate) is given by:

Rate of change (decay rate) = 100 - 13 = 87% = 0.87.

By substituting the parameters into the exponential equation, we have the following;

\(f(x) = 95(0.87)^x\)

When x = 12, we have;

\(f(12) = 95(0.87)^{12}\)

f(12) = 17.86 ≈ 18 milligrams.

The least number of units, x, that should be produced in order for the average total cost per unit to be $7 or less is 600 units.

Total cost = 1200 + 5x

Average total cost per unit = $7

Average total cost = Total cost / number of units

7 = (1200 + 5x) / x

cross product

7 × x = 1200 + 5x

7x = 1200 + 5x

7x - 5x = 1200

2x = 1200

x = 1200/2

x = 600 units

By taking the addition of the values in the table and overestimating a little bit, the correct option is B: $60.00

Here we have the following table of average costs:

Assuming you eat these 3 per day, the total cost in food per day is the sum of all the values in the table.

It gives:

Total cost: $12.98 + $18.95 + $26.58 = $48.51

Notice that these are average costs, so you should budget a little bit over that just in case, then the correct option is $60, which is the first option over the average total cost.

The point (-√2,1) can also be represented as (√3, 5.18) in polar coordinates.

To find the polar coordinates of the rectangular coordinates (-√2,1), we can use the following formulas:

r = √(x² + y²)

θ = tan^⁻1(y/x)

Plugging in the given values of (-√2,1), we get:

r = √((-√2)² + 1²) = √(2 + 1) = √3

θ = tan^⁻1(1/(-√2)) ≈ 2.0344 radians

Note that since the point (-√2,1) is in the second quadrant, we need to add π to the value of θ obtained from the inverse tangent in order to obtain an angle in the interval [0,2π). Thus, we have:

θ ≈ 2.0344 + π ≈ 5.1779 radians

Rounding to 2 decimal places as needed, we get the polar coordinates of (-√2,1) as (r,θ) ≈ (√3, 5.18).

The way to properly subtract and add mixed numbers or fractions with different denominators (The number at the bottom) is to try and transform them so that they have the same denominator. I'll do B since I personally believe that it's the most challenging.

For the transformation, the denominator of the transformed fractions should ideally be the lowest common multiple (LCM) of the two original denominators of the two fractions because it'll create a smaller number for a denominator and won't require simplification later. To guarantee a common denominator, we'll take the both of the fractions and multiply their numerator (The number at the top) and their denominator by the denominator of the other fraction.

Answer:

8848 meters

Step-by-step explanation:

\(1 \: cm = 0.01\:m\\884800 = x \: m\\\\x = 884800\times 0.01\\\\x = 8848\:meters\)

Answer:

The meter is the international system unit of length, here there are some conversions:

So we know 100 cm are equal to 1 meter and we have to pass the 884800 centimeters to meters.

If 1 meter is equal to 100 centimeters, to pass from meters to centimeters we multiply by 100 and from centimeters to meters we divide by 100.

In this case, we need to pass from cm to m, so we divide by 100 the altitude:

884800/100 = 8848 meters

Answer:

\(\begin{cases}y=-5x+1\\y=5x-4 \end{cases}\)

Step-by-step explanation:

Slope-intercept form of a linear equation:

\(\boxed{y=mx+b}\)

where:

Slope formula

\(\boxed{\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}}\)

Equation 1

Define two points on the line:

Substitute the defined points into the slope formula:

\(\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1-6}{0-(-1)}=-5\)

From inspection of the graph, the line crosses the y-axis at y = 1 and so the y-intercept is 1.

Substitute the found slope and y-intercept into the slope-intercept formula to create an equation for the line:

\(y=-5x+1\)

Equation 2

Define two points on the line:

Substitute the defined points into the slope formula:

\(\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-4-1}{0-1}=5\)

From inspection of the graph, the line crosses the y-axis at y = -4 and so the y-intercept is -4.

Substitute the found slope and y-intercept into the slope-intercept formula to create an equation for the line:

\(y=5x-4\)

Conclusion

Therefore, the system of linear equations shown by the graph is:

\(\begin{cases}y=-5x+1\\y=5x-4 \end{cases}\)
