"What is Limit as x approaches negative 14p(x), if it exists?"

Answer:

-1/12

Step-by-step explanation:

3/6 + (-5/6) = -2/6

-2/6 = -4/12

1/4 = 3/12

-4/12 + 3/12 = -1/12

15 is the answer.      3/5 with the denominater would be 9/15

Answer:

There is a difference of 10%

Step-by-step explanation:

In this situation, the theoretical probability, the probability of something based on logic, is 10%. This means that if the spinner was spun 10 times it would land on 1 once. However, the experimental probability, the probability determined by the results of an experiment, is 20%. This number can be found by finding how many times the spinner actually landed on 1. Out of 5 spins, the spinner landed on 1 once. So the experimental probability is 1/5, which is equal to 20%. Therefore, there is a 10% difference in the prediction and simulation.

Answer:

£9.80

Step-by-step explanation:

The calculation of the total value is given below:

Provided that that

The value of 20p coins is £2.80

So 1p = £2.80 ÷ 20

= £0.14

For 50p it would be

= £0.14 × 50

= £7

Now the total value is

= £2.80 +  £7

= £9.80

Answer:

The value of c so that (x + 1) is a factor of the polynomial p(x) = 5x^4 + 7x^3– 2x^2– 3x + c is equal to 1

Solution:

Given polynomial is as follows

Also given that (x+1) is factor of given polynomial p(x).

Need to determine value of constant c.

We will be solving above problem using factor theorem.

Factor theorem says that if ( x – a) is a factor of any polynomial f(x) , then f(a) = 0.

As in our case f(x) = p(x) and factor of p(x) is (x + 1) , which can be rewritten as (x – ( -1)) , so "a" in our case is -1 .

According to factor theorem p(-1) = 0

On substituting x = -1 , in given expression of p(x) we get

[tex]\huge\boxed{\sf Area = 127.2\ miles\²}[/tex]

Step-by-step explanation:

Given:

Radius = r = 9 miles

Degrees = 180°

Required:

Area of Sector = ?

Formula:

[tex]\sf Area \ of \ Sector = \frac{1}{2}r^2 \theta[/tex]

Solution:

Firstly convert degree into radians

Radian = [tex]\sf \frac{\pi}{180} * 180[/tex]

Radian = π

Radian = 3.14 radians

Now, Find Area of sector

Area = [tex]\frac{1}{2} (9)^2 (3.14)[/tex]

Area = (81*3.14)/2

Area = 254.5 / 2

Area = 127.2 miles²

Answer:

C. 48

Step-by-step explanation:

since it's the perimeter is 112 and the width is 8 ft you add 8 + 8 which is 16 and then you subtract it by 112 which gives you 96 then you divide 96 / 2 which gives you the answer of 48

The tree is 20 feet tall if the 6-foot tall man has a 9-foot shadow at the same time a tree standing next to him as a 30-foot shadow.

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

From the right angle triangle,

The ratio of the man height and his shadow is equal to the tree height(h) and its shadow.

6/9 = h/30

h = 20 feet

Thus, the tree is 20 feet tall if the 6-foot tall man has a 9-foot shadow at the same time a tree standing next to him as a 30-foot shadow.

You have to know how to factor polynomials.

2(5x^2-21x-54)

2(5x^2-30x+9x-54)

2(5x(x-6)+9(x-6))

2(5x+9)(x-6)

Answer:

If you know what x is then you can add it to 1 multiply that by 7 to get the answer then simplify, since you cannot simplify whole numbers you know that it is a decimal. To simplify a decimal remove the decimal point and reduce the ratio to a ratio of whole numbers. Multiply the numerator and denominator of the ratio in fraction form by a 10, 100, 1000 i.e., a power of ten to eliminate the decimal. Then the fraction is simplified to be in its lowest terms.

Answer:

B) (-3,-17) and (-5,-25)

Step-by-step explanation:

Answer:

d. 1,600.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

Based on previous research, the standard deviation of the distribution of the age at which children begin to walk is estimated to be 1.5 months.

This means that [tex]\sigma = 1.5[/tex]

Of the following, which is the smallest sample size that will result in a margin of error of 0.1 month or less for the confidence interval?

The sample size has to be n or larger. n is found when [tex]M = 0.1[/tex]. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]0.1 = 2.575\frac{1.5}{\sqrt{n}}[/tex]

[tex]0.1\sqrt{n} = 2.575*1.5[/tex]

Multiplying both sides by 10

[tex]\sqrt{n} = 2.575*15[/tex]

[tex](\sqrt{n})^2 = (2.575*15)^2[/tex]

[tex]n = 1492[/tex]

So the sample size has to be at least 1492, which means that of the possible options, the smallest sample size is 1600, given by option d.

The sample size should be at least 1492, So the possible options, the smallest sample size is 1600, option D is the correct answer

Based on previous research, the standard deviation of the distribution of the age at which children begin to walk is estimated to be 1.5 months. A random sample of children will be selected, and the age at which each child begins to walk will be recorded. A 99% confidence interval for the average age at which children begin to walk will be constructed.

The margin of error tells you how many percentages points your results will differ from the real population value.

[tex]M=z\frac{\sigma}{\sqrt{n} }[/tex]

We need to find our α level, that is the subtraction from 1 by the confidence interval for the average age divided by 2.

[tex]\alpha = \frac{1-0.99}{2}\\ =0.005[/tex]

Now, we need to find z which is 1-α

[tex]1-\alpha \\=1-0.005\\\rm z=2.575[/tex]

The margin of error M

[tex]M=z\frac{\sigma}{\sqrt{n} }[/tex]

Here, [tex]\sigma[/tex] is the standard deviation of the population.

n is the size of the sample.

So,

[tex]\rm M=z\frac{\sigma}{\sqrt{n} } \\\rm0.1=2.575\frac{1.5}{\sqrt{n} } \\\rm0.1\times\sqrt{n} =2.575\times{1.5}\\\rm\sqrt{n} =2.575\times{1.5}\\\rm(\sqrt{n} )^{2} =(2.575\times{1.5})^{2} \\\rm n=1492[/tex]

Hence, the sample size should be at least 1492, So the possible options, the smallest sample size is 1600, option D is the correct answer.
