A rival chocolate company is larger. They have 11 times as many workers.
How many workers are employed at the chocolate company?
Solve on paper. Then check your answer on Zearn.
The number of workers employed at the chocolate company or check the answer on Zearn.
To solve this problem, we'll first set up an equation to represent the given information and then solve it. Let's denote the number of workers at the rival chocolate company as x.
According to the problem, the rival chocolate company has 11 times as many workers as the other company. This can be expressed as:
x = 11 * (number of workers at the other company)
Since the number of workers at the other company is not given, we can use a variable to represent it. Let's use y to represent the number of workers at the other company.
Now we can substitute this into the equation and solve for x:
x = 11 * y
To find the value of x, we need more information about the number of workers at the other company. Without that information, we cannot determine the exact number of workers employed at the chocolate company or solve the equation.
Therefore, without additional data, we cannot determine the number of workers employed at the chocolate company or check the answer on Zearn.

Describe the difference between null vs alternative hypothesis
Statistical hypothesis testing employs the null and alternate hypotheses.
The alternative hypothesis of a test expresses the prediction of an effect or relationship based on your study, while the null hypothesis of the test does not yet predict an effect or an association between the variables.
A statement that there is no relationship between two variables is called a null hypothesis. Another hypothesis is that the two variables are statistically correlated.
Alternative unilateral (directional) or the bilateral (non-directional) hypotheses are also possible. Simple, complex, true, and false are the four main categories of null hypotheses. If the p-value is greater than the statistical significance level, null hypothesis is preferred.

Solve for x. Round to the nearest tenth, if necessary.
Answer:
x = 25.540 degrees
Step-by-step explanation:
When computing the value of x, there are various ways to solve with given information.
The easiest way is to set up the equation: cos(20 degrees) = 24/x
Cosine is adjacent over the hypotenuse.
Multiplying x on both sides, and dividing by cos(20 degrees), we are left with x = 24/cos(20 degrees).Solving for it in a calculator, we are left with 25.540 degrees.Find the exact value of sin П/6.
The exact value of sin(π/6) is 1/2.
To find the exact value of sin(π/6), we can use the unit circle or the trigonometric identity for the sine function. In the unit circle, π/6 corresponds to an angle of 30 degrees, which lies in the first quadrant.
At this angle, the y-coordinate of the corresponding point on the unit circle is 1/2. Since sin(θ) represents the ratio of the opposite side to the hypotenuse in a right triangle, for an angle of 30 degrees, sin(π/6) is equal to 1/2.
Alternatively, we can use the trigonometric identity sin(θ) = cos(π/2 - θ). Applying this identity, we have sin(π/6) = cos(π/2 - π/6) = cos(π/3). Now, π/3 corresponds to an angle of 60 degrees, which lies in the first quadrant.
At this angle, the x-coordinate of the corresponding point on the unit circle is 1/2. Therefore, cos(π/3) = 1/2. Substituting this value back into sin(π/6) = cos(π/3), we get sin(π/6) = 1/2.
In both approaches, we find that the exact value of sin(π/6) is 1/2, indicating that the sine function of π/6 radians is equal to 1/2.

The results of a two-tailed hypothesis test are reported as follows: t(21) = 2.38, p < .05. What was the statistical decision and how big was the samp
The statistical decision based on the reported results of the hypothesis test is that the null hypothesis was rejected at the α = .05 significance level.
The t-value reported is 2.38, and the degrees of freedom are 21. This suggests that the test was likely a t-test with an independent samples design, where the sample size was n = 22 (since df = n - 1).
The p-value reported is less than .05, which indicates that the probability of obtaining the observed results, or results more extreme, under the assumption that the null hypothesis is true, is less than .05. Therefore, the null hypothesis is rejected at the .05 significance level in favor of the alternative hypothesis.
In conclusion, the statistical decision is that there is sufficient evidence to suggest that the population means are not equal, and the sample size was 22. However, we do not have information about the direction of the effect (i.e., whether the difference was positive or negative).

The population N(t) (in millions) of a country t years after 1980 may be approximated by the formula N(t) = 217e0.0102t.When will the population be twice what it was in 1980? (Round your answer to one decimal place.)
The population of the country will be twice what it was in 1980 approximately 67.8 years after 1980, which would be around 2047.
To find out when the population will be twice what it was in 1980, we need to set up an equation and solve for t.
Let's first determine the population in 1980:
N(0) = 217e0.0102(0) = 217
So, the population in 1980 was 217 million.
Now, we want to find out when the population will be twice that amount:
2(217) = 434
We can set up an equation:
434 = 217e0.0102t
Divide both sides by 217:
2 = e0.0102t
Take the natural logarithm of both sides:
ln(2) = 0.0102t
Solve for t:
t = ln(2)/0.0102
t ≈ 67.8
Therefore, the population of the country will be twice what it was in 1980 approximately 67.8 years after 1980, which would be around 2047.

As more trials are conducted, the experimental and theoretical probabilities should get
As more trials are conducted, the experimental and theoretical probabilities should approach each other and become more similar.
The theoretical probability is the expected probability of an event occurring based on mathematical calculations, while the experimental probability is based on actual results from a set of trials or experiments.
In an ideal situation, if the trials are conducted correctly and enough data is gathered, the experimental probability should approach the theoretical probability. This means that the observed results are becoming more consistent with the expected outcomes, and the sample size is becoming large enough to be statistically significant.
However, it's important to note that there may be factors that can affect the outcomes of the trials, such as random variation, bias, or external influences. So, it's important to take these factors into account when interpreting the results of the trials and comparing them to the theoretical probabilities.

If a is uniformly distributed over [−13,21], what is the probability that the roots of the equation x^2+ax+a+48=0 are both real?
The probability that the roots of the equation x^2+ax+a+48=0 are both real is 1/2.
For the roots of the quadratic equation to be real, the discriminant (b^2-4ac) must be greater than or equal to 0. In this case, b=0, a=a, and c=a+48. So we have:
0^2-4(a)(a+48) ≥ 0
Simplifying, we get:
a^2+48a ≤ 0
a(a+48) ≤ 0
The roots will be real if a is either negative or zero. The total range of a is 21 - (-13) = 34. Therefore, the probability of a being negative or zero is:
P(a ≤ 0) = (13+21)/34 = 1/2.

A graph shows the horizontal axis numbered 15 to 48. The vertical axis is numbered 1 to 5. The graph shows an upward trend from 1 to 30 then a downward trend from 30 to 45.
A graph shows the horizontal axis numbered 12 to 56. The vertical axis is numbered 2 to 8. The graph shows an upward trend from 1 to 32 then a downward trend from 32 to 56.
A graph shows the horizontal axis numbered 15 to 54. The vertical axis is numbered 1 to 5. The graph shows an upward trend from 1 to 24, a downward trend from 24 to 27, an upward trend from 27 to 30, a downward trend from 30 to 39, an upward trend from 39 to 45, a downward trend from 45 to 48, then an upward trend from 48 to 51.
To determine which set of data most likely has a mean closest to 29.5, we need to analyze the shape and position of the histograms in relation to the value 29.5.
Looking at the histograms described:
The first histogram ranges from 9 to 48, and the upward trend starts from 1 and ends at 33, followed by a downward trend. This histogram suggests that there may be values lower than 29.5, which would bring the mean below 29.5.
The second histogram ranges from 15 to 48, with an upward trend from 1 to 30 and then a downward trend. Similar to the first histogram, it suggests the possibility of values lower than 29.5, indicating a mean below 29.5.
The third histogram ranges from 12 to 56, and the upward trend starts from 1 and ends at 32, followed by a downward trend. This histogram covers a wider range but still suggests the possibility of values below 29.5, indicating a mean below 29.5.
The fourth histogram ranges from 15 to 54 and exhibits multiple trends. While it has fluctuations, it covers a wider range and includes both upward and downward trends. This histogram suggests the possibility of values above and below 29.5, potentially resulting in a mean closer to 29.5.
Based on the descriptions, the fourth histogram, with its more varied trends and wider range, is most likely to have a mean closest to 29.5.

Answer:
y = - 3x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = (- 3, 1) and (x₂, y₂ ) = (0, - 8)
m = \(\frac{-8-1}{0+3}\) = \(\frac{-9}{3}\) = - 3

Find an equation of the line L. L is perpendicular to y=-2x. points (3,-6)
Answer:
Step-by-step explanation:
If L is perpendicular to the line y = -2x, then the slope of L is the negative reciprocal of -2. So the slope of L is 1/2.
Now we know that the line L goes through the point (3,-6), so we can use the point-slope form of a linear equation to find the equation of L.
The point-slope form of a linear equation is: y - y1 = m(x - x1)
where (x1, y1) is a point on the line, and m is the slope of the line.
Here, (x1, y1) = (3, -6) and the slope of the line is m = 1/2, so the equation is:
y - (-6) = (1/2)(x - 3)
Simplifying this gives us the final equation of the line L:
y = (1/2)x - 3
