Tell whether the following binomial is a factor of the polynomial
binomial- (x+8)
Polynomial- x^5-8x^4+8x-64
Please help :)
Answer:
Given polynomial
x⁵-8x⁴+8x-64= x⁴(x-8)+8(x-8)= (x-8)(x⁴+8)
after factorization of the given polynomial we didn't get any factor (x+8) , hence the following bionomial is not the factor of the polynomial.
Find perimeter of rectangle when length = 4.6m and breadth = 360cm
Answer:
16.4 m²
Step-by-step explanation:
length = 4.6 m
breadth = 360 cm = 360 ÷ 100 = 3.6 m
Perimeter = 2*(l + b)
= 2 * ( 4.6 + 3.6)
= 2 * 8.2
= 16.4 m²

Answer:
increase = 37.38 cm²
You'd like the first way because it took less effort and less chance of a miscalculation.
Step-by-step explanation:
first way:
(just work with the difference in height)
(0.7 x 8.7 x 2) + (0.7 x 18 x 2) = 37.38 cm²
second way:
old total lateral surface area = (31 x 8.7 x 2) + (31 x 18 x 2) = 1655.4
new total lateral surface area = (31.7 x 8.7 x 2) + (31.7 x 18 x 2) = 1692.78
increase = 1692.78 - 1655.4 = 37.38 cm²

Probability -
Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail).Given,

A restaurantis planning to make changes to its menu. In order to decide which potential menu items are most popular with the city's population, the owners will conduct a survey. Which survey methods would produce a representative sample of the city's population
Answer:
Simple random sampling survey method
Step-by-step explanation:
A simple random sampling is an unbiased survey technique Hence it will represent all the parts of the city's population.
In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process
Answer:
hope i helped :)
Step-by-step explanation:
some survey methods that could produce a representative sample of the city's population could be as follows:
o panel sampling
o online surveys
o mail-in surveys
Solve this and put it an inequality.
|x - 7|=x-7
Answer:
x>=7
Step-by-step explanation:
Since the equation on the right is equal to the equation on the left that means that x has to be greater or equal to 7 to make the statement true.
Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations.

A simple random sample of size 51 has sample mean of 70.72. The population distribution is approximately normal, with population standard deviation of 16.25. Determine the correct method of finding a 95% confidence interval for the unknown population mean and compute it. z-method: (66.26, 75.18) Cannot compute: the population size is too small. t-method: (66.15, 75.29) z-method: (66.15, 75.29)
Answer:
z-method: (66.26, 75.18)
Step-by-step explanation:
We have the standard deviation for the population, which means that we use the z-distribution to solve this question.
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 - 0.95}{2} = 0.025[/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 - 0.025 = 0.975[/tex], so Z = 1.96.
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.
[tex]M = 1.96\frac{16.25}{\sqrt{51}} = 4.46[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 70.72 - 4.46 = 66.26
The upper end of the interval is the sample mean added to M. So it is 70.72 + 4.46 = 75.18
The correct answer is z-method: (66.26, 75.18)

Answer:35in.
Step-by-step explanation:
I reccomend splitting it into sections when given problems like this.
The smaller two rectangles would be 5in * 2in which is 10in then just add them together.
For the bigger one, you'd do 5-2 in order to get the missing inches which will be 3+2 once added 5in*3in is 15in.
Finally, add 15+10+10 (15=The middle rectangle and 10=the sides)
Answer:
Break it up into pieces. The answer is 35in^2
Step-by-step explanation:
I took the first rectangle you see which is 5in by 2. Multiply that and you get 10
I then took the second one and is the 5 in by 3in. Multiply those and you get 15
The last one is the exact same as the first one
Add the areas all together and you get the area of the whole shape
Hope that helps
Find the value of x. Round to the

Answer:
cos(33) = 6/X
cos(33)*6= X
X= 5.03202340767254
rounded to the nearest tenth it is 5
therefore X= 5
The value of x in the given digram using trigonometry to the nearest tenth is 7.15.
What is the value of x ?The given image is a right triangle. A right triangle is a triangle that has three sides with one of the angles measuring 90 degrees.
Given an angle and the length of the adjacent side, we are to determine the value of the hypotenuse using cos.
Cos = adjacent / hypotenuse
cos 33 = 6 /h
h = 6 / cos 33
h = 6 / 0.83867
h = 7.15
