How do you find the maclaurin series expansion of f(x)=(1−x)^−2?

Answer:

Step-by-step explanation:

ans will be (c) 11 cm, 7 cm, 2 cm

Step-by-step explanation:

Though the sum of any two sides of a triangle should be always greater than the third side i.e.,

11 + 7 > 2

7 + 2 = 9 < 11

so, no triangle can be formed of such sides.

The hourly rate is 8 dollars because $52-$44 is $8. $44-$36 is also $8. So $36- (the amount for 2 hours) $28 is $8. so in one hour the cost to rent a bicycle is $8.

Answer:

1/16

Step-by-step explanation:

Rational Exponents can be rewritten as Radicals:

[tex](\frac{1}{8})^{\frac{4}{3}}=\sqrt[3]{\frac{1}{8}}^{4}[/tex]

Take the cube root of 1/8 = 1/2.

Raise (1/2) to the 4th power

Step-by-step explanation:

the numerator (top part) of a fractional exponent means "to the power of ...".

the denominator (bottom part) of a fractional exponent means "the ...th root".

so,

(1/8)^(4/3) means the cubic root of 1/8 to the power of 4.

these 2 operations can be done in any sequence.

it is the same if we first put 1/8 to the power of 4 and then get the cubic root, or if we first get the cubic root of 1/8 and then put that result to the power of 4.

to keep the numbers small, I prefer here to start with the cubic root :

cubic root (8) = 2, because 2³ = 8.

and so, cubic root (1/8) = 1/2

(1/2)⁴ = 1/16

that's it.

(1/8)^(4/3) = 1/16

The Unit Normal to the Surface cos(x. y) = e. z - 2 at (1,π,0) is -2 ≤ z ≤ 2.

Let F(x, y, z) = cos(x.y) − e.z + 2 .

A given surface is the same as the set of planes F(x, y, z) = 0.

Since the gradient vector ∇F( 1 , π, 0) is normal to this surface at (1, π, 0) , find this vector and normalize it to get the unit vector normal to this surface.

Differentiate:

∇F(x, y, z) = (−y sin(x y), −x sin(x y), e(z)

or

∇F(1, π, 0) = (0 , 0 , 1).

This vector is already of length 1, so this is sufficient. Alternatively, you can use the vector opposite. Therefore, the two vectors that satisfy the problem are ±k.  At problem point, the surface is flat horizontally.

The total number of adults who attended the play are 210.

Here, we are given that tickets for a play cost $ 7 for students and $ 10 for adults.

Total number of seats = 380

Box office revenue on opening night =  $ 3290

Let the number of adults be x

Then, the number of students will be = (380 - x)

thus, we can form the following equation-

10x + 7(380 - x) = 3290

10x + 2,660 - 7x = 3290

3x + 2,660 = 3290

3x = 3290 - 2660

The sum of the infinite geometric series 16 + 12 + 9 + ... is 64.

To find the sum of an infinite geometric series, you can use the formula:

sum =[tex]\frac a{(1 - r)}[/tex]

where "a" is the first term in the series and "r" is the common ratio between terms.

In this case, the first term is 16 and the common ratio is 3/4, so the sum is:

sum [tex]= \frac{16}{(1 - \frac{3}4)} =\frac{16}{(\frac{1}4)} = 64[/tex]

Therefore, the sum of the infinite geometric series 16 + 12 + 9 + ... is 64.

Note that this formula is only valid if the absolute value of the common ratio is less than 1. If the absolute value of the common ratio is 1 or greater, the series will either converge to a finite value or diverge to infinity, and the sum cannot be calculated using this formula.

By using the concept of percentage, it can be calculated that

65% people are completely satisfied with the car

What is percentage?

Suppose there is a number and the number has to be expressed as a fraction of 100. The fraction is called percentage.

For example 2% means [tex]\frac{2}{100}[/tex]. Here, 2 is expressed as a fraction of 100.

This is a word problem on percentage

Number of people who are completely satisfied with the car = 1495

Total number of people surveyed = 1495 + 210 + 595 = 2300

Percentage of people who are completely satisfied with the car = [tex]\frac{1495}{2300}\times 100[/tex]

If you have two main effects, and one main effect is significant, this means that d. The other main effect and the interaction effect may or may not be significant

A statistically significant result indicates that it is unlikely to be explained solely by chance or random factors. In other words, if there is no true effect in a research study, a statistically significant result has a very low chance of occurring.

The significance level is the threshold at which one can accept whether an event is statistically significant. Researchers use the p-value to determine statistical significance: if the p-value is less than the significance level, the result is statistically significant.

If you have two main effects and one of them is significant, the other one and the interaction effect may or may not be significant.

The probability the researcher will make a type i error 0.10

The hypothesis testing, type I error involves rejecting true null hypothesis also referred to as 'false-positive' conclusion and type II error occurs when false null hypothesis is not rejected. It is also known as 'false negative' conclusion. And they are opposite to each other.

Here we have given that suppose a researcher plans to conduct a test of hypotheses at the 5% significance level. she designs her study to have power of 0.90 at a particular alternative value of the mean

And we need to find the probability the researcher will make a type i error

While looking into the given question,

We know that,

Significance level = 5%

alternative value of the mean = 0.90

Then the probability the researcher will make a type i error is calculated as,

mean = 1 - error

0.90 = 1 - error

=> error = 0.10

The probability of getting a full house is 0.001441 or 0.14%.

When you dealt five cards from a thoroughly shuffled standard check of cards then for the probability of getting a full house we need to know the total number of full house combinations and possible cards hands.

This is calculated by taking the number of possible full house combinations (3,744) and dividing it by the total number of possible 5-card hands (2,598,960). This can be written as :

Mathematically, this can be expressed as:

P(Full House) = 3,744 / 2,598,960 = 0.001441 or 0.14%

Therefore the probability of getting a full house is 0.001441 or 0.14%

The type II error in this hypothesis test will occur when there is lack of enough evidence to conclude that less than 87% of the graduates of the academic program find full-time employment.

It is given to us that -

A certain academic program boasts that 87% of their graduates find full-time employment in their field within the first year of graduation.

The academic director wants to perform a hypothesis test to see if her concern is warranted.

We have to explain the meaning of a type II error for this type of hypothetic test.

In Hypothesis test, type II error occurs when the null hypothesis is not rejected even if it is actually false.

When performing hypothesis test, there are two factors that play an important role -

(a) The significance level of the hypothesis test

(b) The p-value obtained

In the given situation,

Null hypothesis, [tex]H_{0}[/tex]: p = the proportion is equal to 87%, i.e., 0.87

Alternative hypothesis, [tex]H_{A}[/tex]: p = the proportion has reduced than 0.87

The type II error may occur when -

the p-value is greater than the significance level

This condition will arise when there is lack of enough evidence to conclude that less than 87% of the graduates of the academic program find full-time employment.

In such situation, we cannot reject the null hypothesis because the p-value must be greater than the significance level.

Thus, the type II error in this hypothesis test will occur when there is lack of enough evidence to conclude that less than 87% of the graduates of the academic program find full-time employment.
