Find the coefficient of x^2 y^3 in the expansion of (-4x+y)^5. Give your answer as an integer.

Answers

Answer 1

Coefficients are the numbers in front of the variables therefore The coefficient of x^2 y^3 would be (-4)x and 1(y). Anytime there isn’t a coefficient shown in front of a variable the coefficient will always be 1. I hope this helped :)

Adults in Turkey have mean caloric intake of 3500 calories per day (Wikipedia) with a standard deviation of 500 calories. A sample of 25 Ankara University students has an average intake of 3400 calories per day. Is this enough evidence to conclude that Ankara U. students average is not 3500 calories per day? Assume the distribution is normal.
A. State the null and alternative hypotheses.
B. What is the value of the test statistic?
C. Specify the rejection region?
D. State the conclusion.

Answers

Answer:

A) Null hypothesis; H0: μ = 3500

Alternative hypothesis;Ha μ ≠ 3500

B) t = -1

C) the rejection region will be;

p-value < 0.05

D) Conclusion is that there is no sufficient evidence to support the claim that Ankara U. students average is not 3500 calories per day.

Step-by-step explanation:

We are given;

Population mean; μ = 3500

Population standard deviation; σ = 500

Sample mean; x¯ = 3400

Sample size; n = 25

We want to find enough evidence to conclude that Ankara U. students average is not 3500 calories per day.

Thus, the hypothesis is defined as;

A) Null hypothesis; H0: μ = 3500

Alternative hypothesis;Ha μ ≠ 3500

B) sample size is less than 30, thus we will use a t-test.

Formula for the test statistic is;

t = (x¯ - μ)/(σ/√n)

t = (3400 - 3500)/(500/√25)

t = -100/(500/5)

t = -1

C) since the sample is small, let's assume a significance level of 0.05.

Thus,the rejection region will be;

p-value < 0.05

D) from online p-value from t-score calculator attached using;

t = - 1; DF = 25 - 1 = 24; significance level = 0.05 and two tailed hypothesis, we have;

p-value ≈ 0.3273

This is greater than the significance value of 0.05.

Thus, we will fail to reject the null hypothesis and conclude that there is no sufficient evidence to support the claim that Ankara U. students average is not 3500 calories per day.

See attachment :D

Step-by-step explanation:

y = 2/3x + 2

This is in slope-intercept form, y = mx+b. m is the slope, 2/3, and b is the y- intercept, 2. So you know the line intersects with the y-axis at (0,2). The slope is 2/3. So you can move up two points, then over three. Because it's a positive slope, you move right. This leaves you at point (0,3). Connect a line between these two points.

The line intersects with points (-3,0) and (0,2).

Answer:

Step-by-step explanation:

Since the triangles are congruent then corresponding sides are congruent, that is

DE = AB , substitute values

6x - 7 = 11 ( add 7 to both sides )

6x = 18 ( divide both sides by 6 )

We are used to fighting in the summer. Thats when the lands to our north thaw enough for the Vikings to venture south to our lands hoping to steal our livestock and crops. Our walls, however, protect our farms. As the Norsemen try to come ashore, we fight them back with ease. Our arrows, bolts, and rock are more than enough to fend them off as they attempt to land on our beaches. They may not have what is ours, and soon they turn toward other coasts and other forts as ours are too strong for them.Then come the Britons from the south. The Britons claim to this land is admittedly greater than ours. They were here before the Romans and will probably outlast our Saxon rule, but that does not matter today. Today this land belongs to Ida the Saxon king, and we will hold it for him and his heirs. Their numbers cannot stand against our fortifications. Our steel is superior to theirs, as our swords and spears cut through their armor with ease. We have the higher ground, for Bamburg stands on a dolerite outcrop. Not only do we use the rock as our foundation, we have cut into the earth and used it to build our walls, and we launch our rocks toward our enemy as they attempt to storm the hill. With these rocks and our arrows and bolts, we cut half their army down before they even reach our battlements. Their spirit weakens as their forces are cut down, as we easily strike down those foolish enough not to break ranks and run. No man can defeat us once we lock ourselves behind these walls. We have plenty of land and cattle here. We can outlast any siege. Thanks to Lord Ida of Bernecia, we are protected.Lord Ida had us build this stronghold high above the shore, and we are invincible from attacks by land and sea, but now we must deal with airborne enemies as well.The dragons have come out of the East somewhere and bring with them fire. They attack when the sun is high. They know our bows and crossbows are worthless against them, as our arrows and bolts bounce off their thick hide. They swoop down and take our sheep in their claws and maws, returning to whereever they came from before dusk with a fifth of our provisions. The fire drives our bravest men inside as we cower with the women and children, hoping to avoid the death that the dragons bring.Aston, the ironsmith, and his fisherman brother, Aethel, claim to have a solution. They have combined their tools and designed a contraption that might bring the winged monsters out of the sky. Fishing nets with iron barbs launched from paired ballistae. The ballista is a giant crossbow left from the Roman invasions. The contraptions take three men to crank, and aiming the ballistae pairs has proven difficult, but we hope to fight when they return tomorrow.Nets are weighted down with iron spikes. As we launch the projectiles at the dragons, we hope to drop them into the sea, or at least pin them to the ground where our swords and spears can do harm. Aethel believes that dragons falling into the water will surely drown, and Aston believes that we should attack the wings of the grounded dragons so that they cannot escape our mighty warriors. But that lesson is for tomorrow when the dragons return at high noon. Tonight we plan our attack and hope our weapons prove their design.Based on the information found in the passage, which invaders attack the Saxons by land?A the VikingsB the dragonsC the BritonsD the Romans Which organelle captures sunlight and helps in food synthesis?
