The estimate errors in the adjacent side and the hypothenuse are ≅ ±0.29 cm and ≅ ±0.145 cm respectively. The percentage errors in the adjacent side and hypothenuse are 2.009% & 0.502%.

Hypothenuse y₁ = 25/sin x = 25cosec x

Adjacent y₂ = 25/tan x = 25cot x

Opposite angle is 60° = π/3

Possible error, dx ≅ ±0.5° = 0.5 × π/180 = ±π/360

Differentiating y₁ = 25cosec x

dy₁ = -25(cosec x · cot x)dx

dy₁ = -25(cosec (π/3) · cot (π/3))×±π/360

= -25(2/√3)(1/√3)(±π/360)

= ≅ ±0.145 cm

Similarly

dy₂ = -25 cosec²x .dx

dy₂ = -25 cosec²(π/3) .×±π/360

= -25(2/√3)²×±π/360

≅ ±0.29 cm

So the errors in the hypothenuse = ±0.145 cm

Error in the adjacent side = ±0.29 cm

Percentage error in the adjacent side = 0.29/(25/√3) = 2.009 %

A dependent variable is precisely what it sounds like, just like an independent variable. It is something on which other elements depend.

A test score, for instance, may be a dependent variable because it could vary based on a number of variables, including how much you studied, how much sleep you got the night before the test, and even how hungry you were. Typically, when attempting to establish a connection between two variables, the goal is to determine what causes the dependant variable to vary in the manner that it does.

Many people struggle to recall which variable is the independent variable and which variable is the dependent variable.

The probability of there is one faulty light is 0.60%, There are two faulty lights is 0.12% and There is at least one faulty light is 0.60%.

The likelihood that an event will occur is measured by probability. It is difficult to make a complete prediction for many events. By using it, we are only able to forecast the likelihood of an event, or how likely it is, to occur. Between 0 and 1, where 1 denotes a certain event and 0 denotes an impossibility, is the range of probability. For students in class 10, probability is a crucial subject because it clarifies all of the fundamental ideas. In a sample space, there is a probability of 1 for each event.

Answer: The building is in the form of a cylinder surmounted by a cone. To find the outer surface area of the building, we need to find the total surface area of the cylinder and the cone and add them together.

The total surface area of the cylinder = 2πr^2 + 2πrh = 2π(7^2) + 2π(7)(24) = 2π(49) + 2π(168) = 98π + 336π = 434π square meters

The total surface area of the cone = πr^2 + πr√(r^2 + h^2) = π(7^2) + π(7)(√(7^2 + 24^2)) = 49π + 49π(√(625)) = 49π + 49π(25) = 49π + 1225π = 1274π square meters

The outer surface area of the building is the sum of the total surface area of the cylinder and the cone, which is 434π + 1274π = 1708π square meters.

Answer:

A. No, because (-1) and (-1, -2) have the same input value.

Step-by-step explanation:

So what exactly is a function? It's very similar to a relation where there is input and for each input we have some output and sometimes multiple. The difference is in a function there is only one output for each input. Now the outputs of two different inputs can be the same, such that the input 2 and 3 will both output 4 or any value, but we cannot have an input such as 2 outputting 3 and 4 since we can only have one output for each input.

In the table given, the input "-1" outputs "2" and -2" which means the table  does not represent a function.

This makes "A" the correct answer to whether it's a function or not and explanation.

We can be 90% confident that the interval [76.4, 79.3] contains the true mean monthly percentage of on-time departures. This means that we are highly confident that the true mean monthly percentage of on-time departures lies within this interval.

To find the 90% confidence interval, we first need to calculate the margin of error. To calculate this, we need to use the standard error, which is calculated by dividing the standard deviation by the square root of the sample size. The standard deviation for the given data is 2.2 and the sample size is 72 (6 years × 12 months). So, the standard error is calculated as 2.2/√72 = 0.44. The margin of error is then calculated by multiplying the standard error by the critical value for 90% confidence, which is 1.645. The margin of error is therefore 0.44 × 1.645 = 0.72. The confidence interval is then calculated by adding and subtracting the margin of error from the sample mean. The sample mean is 77.8, so the 90% confidence interval is 77.8 ± 0.72, or [76.4, 79.3]. This means that we are highly confident that the true mean monthly percentage of on-time departures lies within this interval.

How the transformations below affect length, angles or both?

The degree and the leading coefficient of a polynomial function determine the end behavior of the graph.

When referring to a function, "end behaviour" refers to the character of the value as the function parameter becomes closer to +∞ and -∞.

In the given table for f(x), we see that for every value of x, function f(x) is decreasing.

f(-2) = 48

f(0) = 12

f(2) = 3

f(3) = 1.5

In other words as the value of x increases, f(x) is approaching towards 0.

Now we take another function g(x) =

Now we plug in the values of x to get the values of g(x)

g(-1) =2^-1-5  

    = 1-10/2

    = -9/2

    = -4.5

g(0) =  2^0-5

     = 1 - 5 = -4

g(2) = 2^2-5

     = 4 - 5 = -1

g(3) = 2^3-5

     = 8 - 5= 3

Now we find that g(x) is increasing with the values of x.

Now we take third function h(x).

By analyzing the given graph we find

h(-4) = 2

h(0) = 3

h(1) = 5

So when we are increasing the value of x function h(x) is increasing.

Finally we conclude by the options given that f(x) is the only function which tends to 0 with the increase in the values of x.

Let A and B be two countable sets. Then there exists a bijective function f from A to B.

Since f is onto, for every element b in B, there exists a unique element a in A such that f(a)=b. This implies that the number of elements in B is equal to the number of elements in A, i.e. B is also countable.

Formally, if A = {a1, a2, ..., an}, then B = {f(a1), f(a2), ..., f(an)}. Since f is onto, B has n elements, which implies that B is countable.

Let A be a countable set and let B be a set with an onto function f from A to B. Since A is countable, it can be written as an infinite sequence of distinct elements an, where n is a natural number. To show that B is also countable, we can construct a one-to-one correspondence between the elements of A and B. We can do this by assigning bi to the element ai in A, for each i. Thus, we can write B as an infinite sequence of distinct elements bn, where n is a natural number. Therefore, B is countable.

The most obvious concern is those who chose to respond to the survey may have different eating habits from those who did not respond.

One of the major worries when conducting a survey is that people who choose to reply can differ from those who choose not to. The term for this is nonresponse bias. The representativeness of the sample may be impacted by the traits, opinions, or actions of respondents that differ from those of non-respondents.

In this given case, the chef issued a survey to 1000 families, but only 150 of them responded, or 15% of the households. It's probable that those who are very interested in food or cooking will respond to the poll more frequently than others who aren't. Due to the possibility that the eating patterns of individuals who replied may not be typical of the total population, this could cause the sample to be skewed. Thus, the chef would need to consider the nonresponse bias when interpreting the results of the survey.
