Answer:

1:3

Step-by-step explanation:

both divide by 60 so do 60 divided by 60 which is one

then 180 divided by 60 which is three

this gives you the answer

Answer:

1:3

Step-by-step explanation:

a ratio is basically the same as a fraction just in a different form. so it would be 60/180 simplified. both 60 and 180 can be divided by 60. so you would divide both numbers by 60 to get 1/3. this cannot be simplified any further. then to put it as a ratio it would just be 1:3

A 10% increase in cigarette prices has been found to result in a 4% decrease of smokers.

An increase in cigarette price will result in a decrease in the demand for cigarettes.

Since more money needs to be spent to but the same product, less consumers can be able to afford it.

Therefore, a 10% increase in cigarette prices has been found to result in a 4% decrease of smokers.

The probability that the project will take 224 days or longer is 0.1587.

This is a question on the normal probability distribution.

To expiate this, standardize the 95 days.

The standardized score is calculated by subtracting the value from the mean and dividing it by the standard deviation.

z = (x - xbar) ÷ σ

x = 224 days

xbar = mean = 214 days

σ = standard deviation = √(variance) = √100 = 10

z = (224 - 214) ÷ 10 = 1

To calculate the probability that the project will be finished in 95 days or less, P(x ≥ 224) = P(z ≥ (1))

For these probabilities, use data from the normal probability table.

P(x ≥ 224) = P(z ≥ (1)) = 1 - 0.8413 = 0.1587

Based on the given sample input and output, it appears that the `invert_dict` Python function is correctly inverting the dictionary.

The function takes a dictionary as input and produces an output where the keys and values of the input dictionary are swapped.

In the given example, the input dictionary is `{1: 10, 2: 10, 3: 20}`. After applying the `invert_dict` function, the output is `{10: [1, 2, 3], 20: [3]}`. This output indicates that the keys from the input dictionary have become values in the output, and the values from the input dictionary have become keys in the output.

Additionally, the function correctly handles duplicate values in the input dictionary by creating a list of keys associated with each unique value in the output dictionary.

Therefore, based on the provided sample input and output, it can be concluded that the `invert_dict` function is implemented correctly and successfully inverts the given dictionary.

Tyler charges $8 for an adult ticket.

It is given that Tyler charges $t for adult tickets and $5 for child tickets.

No. of tickets sold by him on Monday is 12 child tickets and 9 adult tickets.

No. of tickets sold by him on Tuesday is 20 child tickets and 4 adult tickets.

Therefore,

Tyler earned $12 X 5 + $9 X t on Monday

= $9t + $60

Tyler earned $20 X 5 + $4 X t on Tuesday

= $4t + $100

According to the problem, the earnings on both the days are same. Hence we get the linear equation as follows

9t + 60 =  4t + 100

bringing all the variables, i.e t's to LHS and constants to RHS we get

9t - 4t = 100 - 60

or, 5t = 40

Bringing 5 to RHS we get

t = 40/5

or, t = 8

Therefore, t = $8

The most likely correlation coefficient for the set of data shown is -0.872.

To determine the most likely correlation coefficient for the set of data, we need to examine the values provided: –0.872, –0.191, 0.191, and 0.872.
The correlation coefficient is a value between -1 and 1 that indicates the strength and direction of the linear relationship between two variables.
Since all the given values are positive (0.191 and 0.872) or negative (-0.191 and -0.872), we can conclude that the correlation coefficient is negative.
Out of the two negative values, -0.872 is closer to -1 than -0.191, so it is more likely the correlation coefficient for the given data set.
Therefore, the most likely correlation coefficient for the set of data shown is -0.872.

Step-by-step explanation:

20 workers finish work in 21 days.

the necessary work effort is 20×21 = 420 workdays.

the same effort is needed even if the overall time is shorter.

x workers in 15 days.

x × 15 = 420

x = 420/15 = 28 workers.

so, 28-20 = 8 additional workers are needed to finish the work in 15 days.

Answer:

logx a + logx b

Step-by-step explanation:

To find the equation of a line in slope-intercept form (y = mx + b) that passes through the points (-2, 2) and (7, -4), we first need to determine the slope (m) of the line.

The slope (m) can be calculated using the formula:

m = (y2 - y1) / (x2 - x1)

Substituting the coordinates (-2, 2) and (7, -4) into the formula, we get:

m = (-4 - 2) / (7 - (-2)) = -6 / 9 = -2/3

Now that we have the slope (m), we can use it along with one of the given points to find the y-intercept (b).

Let's use the point (-2, 2) and substitute the values into the slope-intercept form:

2 = (-2/3)(-2) + b

2 = 4/3 + b

b = 2 - 4/3

b = 2/3

Therefore, the equation of the line in slope-intercept form is:

y = (-2/3)x + 2/3

By using the formula for slope, we calculate the slope of the line passing through the given points. Substituting one of the points into the slope-intercept form equation, we solve for the y-intercept. Finally, we combine the slope and y-intercept to obtain the equation of the line in slope-intercept form, which is y = (-2/3)x + 2/3.

The given statement, "The law of diminishing marginal product helps to explain why supply curves are generally upward sloping," is false (F) because it suppose to be the law of supply, not the law of diminishing.

The statement is indeed false because it confuses the law of diminishing marginal returns with the law of supply. The law of diminishing marginal returns states that as more units of a variable input are added to a fixed input, the marginal product of the variable input will eventually decrease. This law is important in production theory but has no direct relationship with the shape of supply curves.

On the other hand, the law of supply states that as the price of a good or service increases, the quantity supplied by producers will also increase. This is due to the fact that producers are willing to produce more at higher prices in order to maximize their profits.

Therefore, the upward slope of supply curves is a result of the law of supply, not the law of diminishing marginal returns.

Answer:

It’s option A, Choi’s option A

Step-by-step explanation:

Answer:

all 3 options are true : A, B, C

Step-by-step explanation:

warning : it has come to my attention that some testing systems have an incorrect answer stored as right answer for this problem.

they say that A and C are correct.

but I am going to show you that if A and C are correct, then also B must be correct.

therefore, my given answer above is the actual correct answer (no matter what the test systems say).

originally the information about the alignment of the point F in relation to point E was missing.

therefore, I considered both options :

1. F is on the same vertical line as E.

2. F is not on the same vertical line as E.

because of optical reasons (and the - incomplete - expected correct answers of A and C confirm that) I used the 1. assumption for the provided answer :

the vertical line of EF is like a mirror between the left and the right half of the picture.

A is mirrored across the vertical line resulting in B. and vice versa.

the same for C and D.

this leads to the effect that all 3 given congruence relationships are true.

if we consider assumption 2, none of the 3 answer options could be true.

but if the assumptions are true, then all 3 options have to be true.

now, for the "why" :

remember what congruence means :

both shapes, after turning and rotating, can be laid on top of each other, and nothing "sticks out", they are covering each other perfectly.

for that to be possible, both shapes must have the same basic structure (like number of sides and vertices), both shapes must have the same side lengths and also equally sized angles.

so, when EF is a mirror, then each side is an exact copy of the other, just left/right being turned.

therefore, yes absolutely, CAD is congruent with CBD. and ACB is congruent to ADB.

but do you notice something ?

both mentioned triangles on the left side contain the side AC, and both triangles in the right side contain the side BD.

now, if the triangles are congruent, that means that each of the 3 sides must have an equally long corresponding side in the other triangle.

therefore, AC must be equal to BD.

and that means that AC is congruent to BD.

because lines have no other congruent criteria - only the lengths must be identical.
