ANSWER PLSSS THANK YOUUUUU

Answer:

Step-by-step explanation:

I plugged in the values to a calculator

The coordinates of the function y = x are related in that for every input value of x, there is a corresponding output value of y. This creates a set of ordered pairs (x,y), where the x-coordinate represents the input value and the y-coordinate represents the output value.

ii. Not all functions have inverse relations. For a function to have an inverse relation, it must be a one-to-one function, which means that each input value maps to a unique output value. If the function is not one-to-one, then multiple input values may map to the same output value, making it impossible to find a unique inverse for the function.

iii. If a function is one-to-one, then its inverse relation will also be a function. The inverse function is defined as the reflection of the original function across the line y = x, and since the line y = x passes the vertical line test, the inverse function will also pass the vertical line test and be a function.

iv. Two functions that are their own inverses are y = -x and y = 1/x.

For y = -x, the inverse function is obtained by switching the x and y variables: x = -y, which can be rewritten as y = -x. Therefore, y = -x is its own inverse.

For y = 1/x, the inverse function is obtained by switching the x and y variables and solving for y: x = 1/y, which can be rewritten as y = 1/x. Therefore, y = 1/x is also its own inverse.

v. A function is its own inverse if its inverse function is identical to the original function, which means that applying the function twice in succession results in the same input value. This can be expressed mathematically as f(f(x)) = x, where f(x) is the function and x is the input value. In other words, the composition of the function with itself results in the identity function.

If two variables are correlated, a change in one must directly produce a change in the other. (False)

Correlation is a statistical measure that indicates the extent to which two or more variables fluctuate together. It is a value between -1 and 1 that represents the strength of the relationship between two variables.

False. If two variables are correlated, a change in one may or may not directly produce a change in the other. Correlation means that there is a relationship between two variables, but it does not necessarily mean that one causes the other. It's possible for two variables to be correlated without any causal relationship between them.

Answer:

x = 61°

Step-by-step explanation:

Since the lower left angle equals to 90°, the other angle on the right must also equal 90°.  Subtract 29 from 90° to get 61° as your x value and as your final angle answer.

Answer:

61°

Step-by-step explanation:

The dotted angke is a right angle which is 90° so,

We can solve for x using algebra

Minimal sedation is characterized by c) less than 50% N2O in the first stage of the continuum.

Minimal sedation is defined as a state in which the patient is able to respond normally to verbal commands, breathe on their own and maintain stable blood pressure and heart rate. It is achieved by administering a small dose of a sedative or anxiolytic medication.

Minimal sedation is a light form of sedation that allows the patient to remain conscious and responsive throughout the procedure, and it helps the patient to relax and reduce anxiety.

It is considered a safer option than deeper forms of sedation as the patient remains able to breathe on their own, which reduces the risk of complications. This level of sedation is often used in procedures such as dental work, minor skin procedures, and diagnostic tests.

Sample = 102 nests
Failed nests = 64

Proportion of failed nests = p = 64/102 = 0.6275

95% interval is given as:

p ± z x √ ( p( 1-p /n))

Note that

z = z-score related to 95% = 1.96

so

0.6275 ± 1.96 x (√(0.6275 (1-0.6275) /102) )

0.6275  ±  0.09382660216

Full Question:

One difficulty in measuring the nesting success of birds is that the researchers must count the number of eggs in the nest, which is disturbing to the parents. Even though the researcher does not harm the birds, the flight of the bird might alert predators to the presence of a nest. To see if researcher activity might degrade nesting success, the nest survival of 102 nests that had their eggs counted, was recorded. Sixty-four of the nests failed (i.e. the parent abandoned the nest.)

a) Construct and interpret a 95% confidence interval for the proportion of nest failures in the population I

b) The usual nest failure rate of these birds is 29%. Based on the confidence interval from part (a), is this consistent with the theory that the researcher's activity affects nesting success? Justify your answer with an appropriate statistical

Answer:

Below.

Step-by-step explanation:

The cosine is also negative in Quadrant III.

sin^2 O + cos^2 O = 1

cos^2 O = 1 - sin^2 O

= 1 - (-sqrt(6)/4)^2

= 1 -  (6/16)

=  16/16 - 6 /16

= 10/16

So cos O = -sqrt(10/16)

= -sqrt(10)/4.

-6(4 + 5v) - 3 = -57

Use distributive properties

-24 -30V -3 = -57

Combine like terms

-27 -30v = -57

Add 27 to both sides

-30v = -30

Divide both sides by -30

V=1

Answer:

v = 1

Step-by-step explanation:

-6(4 + 5v) - 3 = -57

Add 3 to each side

-6(4 + 5v) - 3+3 = -57+3

-6(4 + 5v)  = -54  

Divide by -6 on each side

-6(4 + 5v)  / -6 = -54/-6

4+5v = 9

Subtract 4 from each side

4+5v-4 = 9-4

5v = 5

Divide each side by 5

5v/5 = 5/5

v =1

a) The probability that at least 879 actually did vote is given as follows:

P(X≥879​) = 0.0244.

b) The result suggests that there is enough evidence to consider that the proportion is greater than 69%, as the probability is less than 0.05.

The z-score of a measure X of a variable that has mean symbolized by \(\mu\) and standard deviation symbolized by \(\sigma\) is obtained by the rule presented as follows:

\(Z = \frac{X - \mu}{\sigma}\)

The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with \(\mu = np, \sigma = \sqrt{np(1-p)}\).

The parameters of the binomial distribution for this problem are given as follows:

n = 1227, p = 0.69.

Hence the mean and the standard deviation are given as follows:

The probability that at least 879 people voted, using continuity correction, is one subtracted by the p-value of Z when X = 878.5, hence:

Z = (878.5 - 846.63)/16.2

Z = 1.97

Z = 1.97 has a p-value of 0.9756.

1 - 9756 = 0.0244 = 2.44%.

(continuity correction is used because the binomial distribution is discrete, while the normal distribution is continuous).

Answer:

Step-by-step explanation:

Answer:

x + y + z = 28,000

0.035x + 0.0425y + 0.0475z = 1160

z = 0.75x

Step-by-step explanation:

Let x = amount invested at 3.5%.

Let y = amount invested at 4.25%.

Let z = amount invested at 4.75%.

The total amount is $28,000.

Equation 1:

x + y + z = 28,000

The total interest is $1,160.

Equation 2:

0.035x + 0.0425y + 0.0475z = 1160

"The amount of money in the 4.75% account was 75% of the

amount of money in the 3.5% account."

Equation 3:

z = 0.75x

The system of equations is:

x + y + z = 28,000

0.035x + 0.0425y + 0.0475z = 1160

z = 0.75x

Answer:

x = 7

Step-by-step explanation:

From the above question, we are told that:

∠A and ∠B vertical angles.

It is important to note that vertical angles are equal to each other

Hence:

∠A = ∠B

From the question,

∠A = (5x−2)°

∠B = (3x+12)°

Hence:

(5x−2)°= (3x+12)°

5x - 2 = 3x + 12

Collect like terms

5x - 3x = 12 +2

2x = 14

x = 14/2

x = 7

Answer:

Step-by-step explanation:

The number that is not equal to the others is d.

a. 0.84% is equal to 0.0084 in decimal form.

b. (0.21)(0.04) is equal to 0.0084.

c. 8.4 * \(10^-^2\) is equal to 0.084. This is the same as 8.4 divided by 100, which is 0.084.

d. This is the number that is not equal to the others. We don't have the value of d.

e. 21/25 * \(10^-^2\) is equal to 0.0084. When we divide 21 by 25 and multiply the result by \(10^-^2\), we get 0.0084.

To summarize, all of the given numbers (a, b, c, and e) are equal to 0.0084 except for d, which doesn't have a specified value. Therefore, d is the number that is not equal to the others.

\(3x^{2} -16x -12\)        Find two numbers that multiply to -36 and add up to get -16

                           -18 and 2 works out.

\(3x^{2}\) - 18x +2x - 12     Now group it  

(3\(x^{2}\) -18x) ( 2x - 12)   factor it out

3x( x -6)  2(x-6)       factor out x-6

(x-6)(3x+2)

The answer is b=18. To solve, multiply 6 by 3 to get 18. This is called doing the inverse operation. Since the equation is a division equation, we would have to multiply in order to find the missing variable.
