Answer:

70 cds in 2022

Step-by-step explanation:

each year number of dvds being sold is decreasing by 15. In 2010, it was 250. 5 years later, it was 175.

250-175=75.

75/5=15.

15x7=105.

175-105=70.

in 2010 it was 250 and 250+150=400.

in 2000, it was y=400-15x

The roots of the equation x^2+bx+c=0 are −4 and 2. Find b.

Answers

first, love the killua profile picture ! i love hunterxhunter i am currently on season 5, episode 44 or 45 aka 119 or 120 but anyways,

answer:

b = 2

step-by-step explanation:

because its roots are -4 and 2,

and a = 1 [The coefficient of [tex]x^2[/tex]] we know that [tex]x^2 + bx + c = (x - (-4)) (x-2)=(x+4)(x-2) = 0.[/tex]

using the distributive property we get,

[tex]x^2 + 2x - 8 = 0.[/tex]

by equating coefficients (common strategy for partial fractions and undetermined coefficient method of solving ODE), we get b = 2 and c = -8 ( solved c just for fun guess :) ) .

Answers

The correct answer is A

Answer: A. -40

Step-by-step explanation:

-4 x -2 equals 8, 8 times -5 equals -40

Any negative number times another negative number equal a positive number. That number would be 8, but then you multiply 8 which is a possitive number by -5 which is a negative number you would get a negative number again (-40). Is it a trick question or something?

Answers

The second one - but you rewrote it wrong

The equation that represents the graph is g(x) = |x + 4| - 10.

The correct option is B.

What is transformation on the graphs?

Let the functions f(x) and g(x) be two real functions.

And g (x) = f (x) + k, where k is real numbers.

The function can be sketched by shifting f (x), k units vertically.

The direction of shift can be found by the value of k:

if k > 0, the base graph shifts k units up, and

if k < 0, the base graph shifts k units down.

The function provided by the basic function f(x) and the constant

g(x) = f(x - k),

may be drawn by horizontally moving the f(x) k unit coordinates.

The shift's direction depends on the value of k. Specifically,

The base graph moves k units to the right if k > 0, and

The base graph moves k units to the left if k < 0.

Since the graph of the parent function is g(x) = |x|, the transformed graph is obtained by shifting it 4 units to the left and 10 units down. This can be achieved by applying the following transformations to the parent function:

Shift 4 units to the left: g(x + 4) = |x + 4|

Shift 10 units down: g(x + 4) - 10 = |x + 4| - 10

Therefore, the equation for the transformed function is g(x + 4) - 10 = |x + 4| - 10.

Suppose that 20% of the subscribers of a cable television company watch the shopping channel at least once a week. The cable company is trying to decide whether to replace this channel with a new local station. A survey of 100 subscribers will be undertaken. The cable company has decided to keep the shopping channel if the sample proportion is greater than 0.27. What is the approximate probability that the cable company will keep the shopping channel, even though the true proportion who watch it is only 0.20

Answers

Answer:

There is approximately 4% chance that the cable company will keep the shopping channel, even though the true proportion who watch it is only 0.20.

Step-by-step explanation:

The random variable X can be defined as the number of subscribers of a cable television company who watch the shopping channel at least once a week.

X follows a Binomial distribution with parameters n = 100 and p = 0.20.

But the sample selected is too large and the probability of success is close to 0.50.

So a Normal approximation to binomial can be applied to approximate the distribution of X if the following conditions are satisfied:

1. np ≥ 10

2. n(1 - p) ≥ 10

Check the conditions as follows:

 [tex]np=100\times 0.20=20>10\\\\n(1-p)=100\times 0.80=80>10[/tex]

Thus, a Normal approximation to binomial can be applied.

[tex]\hat p\sim N(p,\frac{p(1-p)}{n})[/tex]

Compute the approximate probability that the cable company will keep the shopping channel, even though the true proportion who watch it is only 0.20 as follows:

[tex]P(\hat p>0.27)=P(\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}>\frac{0.27-0.20}{\sqrt{\frac{0.20(1-0.20}{100}}})[/tex]

                   [tex]=P(Z>1.75)\\=1-P(Z<1.75)\\=1-0.95994\\=0.04006\\\approx 0.04[/tex]

Thus, there is approximately 4% chance that the cable company will keep the shopping channel, even though the true proportion who watch it is only 0.20.

How do you do this question?

Answers

You're very close. The answers you've selected are correct, but there's one third series that's also alternating. Choice C is also an answer due to the [tex](-1)^n[/tex] term.

Any alternating series is in the form [tex]\displaystyle \sum (-1)^n*a_n[/tex] or [tex]\displaystyle \sum (-1)^{n+1}*a_n[/tex] where [tex]a_n[/tex] is any sequence.

Choice E comes close, but the 2n being the exponent means that we don't have alternating signs (positive, negative, positive negative, etc). Why is this? Well notice how 2n is even regardless of what integer n we pick. Raising any negative number to an even power results in a positive value.

Eg: (-7)^2 = 49 and (-3)^4 = 81

This means that all of the terms of sequence E are going to be positive. The terms do not bounce back and forth between positive and negative.

Put another way, [tex](-1)^{2n} = \left((-1)^2\right)^n = 1^n = 1[/tex]

So [tex]\displaystyle \sum_{n=0}^{\infty} (-1)^{2n}\frac{1}{n+3} = \sum_{n=0}^{\infty} \frac{1}{n+3}[/tex]

And it's why choice E is not one of the answers.

Answers

Answer:

{x | x ≤ 6}

Step-by-step explanation:

Given

y = √(6 - x)

Required

Determine the domain

We start by setting 6 - x to ≥ 0.

i.e.

6 - x ≥ 0

Add x to both sides

6 - x + x ≥ 0 + x

6 ≥ x

This can be rewritten as

x ≤ 6

Using set builder, the above van be represented as: {x | x ≤ 6}

Ian walks down a sloped path. After 6 minutes, he is 3 m above street level. Write the equation in slope-intercept form of the line that represents Ian’s height above street level, y, over time x, if he knows the path is parallel to another path with equation y = -2/3x + 12

Answers

Answer:

y=-2/3x+7

Step-by-step explanation:

Since you know the path is parallel to the equation y+-2/3x+12, you already know the slope is -2/3.

It says y is the height above street level, so that is 3. The problem says x is time, which is 6, so all you have to solve for is the y intercept.

3 (y, or the height above street level) = (-2/3) 6 (x, or time) + b (unknown y intercept)

3 = -4 + b

7 = b

So, y = -2/3x + 7

2) Since angles AEC and DEB are congruent, set them up also to equal each other, then solve. : 6x + 20 = 10x. Now solve for x

3) Since AEC and DEB are congruent, they have the exact same angle measurement. Because of this, you are able to set the two equations equal to each other, then solve for x.

Answers

Answer:

Ellen sold 42 cans and they sold 114 cans lastweek (both Ellen and Jordan)

Step-by-step explanation:

The oroginal ratio is 7:12 for every 12 cans ellen collects Jordan collects 7 so inorder to find the number of cans Ellen sold you have to figure out what 7 was multiplied by to get 42, and that would be 6. Then you multiply 12 by 6 and get 72 so ELlen sold 72 cans.

Now the new ratio is 42:72 when you add them together you get 114 so they sold (together) 114 cans last week.

Write a 2-3 sentence summary about Egypt's background:please help, I've been reading sentences over and over again and i can't grasp onto it. it would be very much appreciated... Background: The regularity and richness of the annual Nile River flood, coupled with semi-isolation provided by deserts to the east and west, allowed for the development of one of the world's great civilizations. A unified kingdom arose circa 3200 B.C., and a series of dynasties ruled in Egypt for the next three millennia. The last native dynasty fell to the Persians in 341 B.C., who in turn were replaced by the Greeks, Romans, and Byzantines. It was the Arabs who introduced Islam and the Arabic language in the 7th century and who ruled for the next six centuries. A local military caste, the Mamluks took control about 1250 and continued to govern after the conquest of Egypt by the Ottoman Turks in 1517. Completion of the Suez Canal in 1869 elevated Egypt as an important world transportation hub. Ostensibly to protect its investments, Britain seized control of Egypt's government in 1882, but nominal allegiance to the Ottoman Empire continued until 1914. Partially independent from the UK in 1922, Egypt acquired full sovereignty from Britain in 1952. The completion of the Aswan High Dam in 1971 and the resultant Lake Nasser have reaffirmed the time-honored place of the Nile River in the agriculture and ecology of Egypt. A rapidly growing population (the largest in the Arab world), limited arable land, and dependence on the Nile all continue to overtax resources and stress society. The government has struggled to meet the demands of Egypt's fast-growing population as it implements far-reaching economic reforms, including the reduction of select subsidies, large-scale infrastructure projects, energy cooperation, and foreign direct investment appeals.Inspired by the 2010 Tunisian revolution, Egyptian opposition groups led demonstrations and labor strikes countrywide, culminating in President Hosni MUBARAK's ouster in 2011. Egypt's military assumed national leadership until a new legislature was in place in early 2012; later that same year, Muhammad MURSI won the presidential election. Following protests throughout the spring of 2013 against MURSI's government and the Muslim Brotherhood, the Egyptian Armed Forces intervened and removed MURSI from power in July 2013 and replaced him with interim president Adly MANSOUR. Simultaneously, the government began enacting laws to limit freedoms of assembly and expression. In January 2014, voters approved a new constitution by referendum and in May 2014 elected former defense minister Abdelfattah ELSISI president. Egypt elected a new legislature in December 2015, its first Hose of Representatives since 2012. ELSISI was reelected to a second four-year term in March 2018. In April 2019, Egypt approved via national referendum a set of constitutional amendments extending ELSISIs term in office through 2024 and possibly through 2030 if re-elected for a third term. The amendments would also allow future presidents up to two consecutive six-year terms in office, re-establish an upper legislative house, allow for one or more vice presidents, establish a 25% quota for female legislators, reaffirm the militarys role as guardian of Egypt, and expand presidential authority to appoint the heads of judicial councils.
