Tail winds push the plane along much faster.
A plane traveling at the rate of 300 miles per
hour and having a tail wind of 40 miles per
hour actually makes a speed of 340 miles per
hour.
Ilow far is it from Newfoundland to Iceland,
if the trip was made in 4 hours and the plane
had an average speed of 500 miles per hour
with a tail wind of 30 miles per hour?

Answer:

[tex]90y^4-120y-360y^3+30y^2 = 30y((y - 4)(3y^2+1))[/tex]

Step-by-step explanation:

Given

[tex]90y^4-120y-360y^3+30y^2[/tex]

Required

Simplify

[tex]90y^4-120y-360y^3+30y^2[/tex]

Factor out 30y

[tex]90y^4-120y-360y^3+30y^2 = 30y(3y^3 - 4 - 12y^2 + y)[/tex]

Reorder the expression

[tex]90y^4-120y-360y^3+30y^2 = 30y(3y^3 - 12y^2 +y - 4 )[/tex]

Factorize

[tex]90y^4-120y-360y^3+30y^2 = 30y(3y^2(y - 4) +(y - 4) )[/tex]

Combine the factors

[tex]90y^4-120y-360y^3+30y^2 = 30y((3y^2+1)(y - 4))[/tex]

Rewrite as:

[tex]90y^4-120y-360y^3+30y^2 = 30y((y - 4)(3y^2+1))[/tex]

Step-by-step explanation:

Answer:

[tex]Brown = 2400[/tex]

[tex]Feliz = 3384[/tex]

[tex]Undecided = 216[/tex]

Step-by-step explanation:

Given

[tex]N = 6000[/tex] -- population

[tex]n = 250[/tex] -- sample

From the sample, the proportions are:

[tex]B = 100[/tex] -- Brown

[tex]F=141[/tex] -- Feliz

[tex]U = 9[/tex] -- undecided

Required

Describe the actual population

The actual is calculated using:

[tex]Actual = \frac{p}{n} * N[/tex]

So, for Brown

[tex]Brown = \frac{100}{250} *6000[/tex]

[tex]Brown = \frac{100*6000}{250}[/tex]

[tex]Brown = \frac{600000}{250}[/tex]

[tex]Brown = 2400[/tex]

For Feliz

[tex]Feliz = \frac{141}{250} * 6000[/tex]

[tex]Feliz = \frac{141* 6000}{250}[/tex]

[tex]Feliz = \frac{846000}{250}[/tex]

[tex]Feliz = 3384[/tex]

For undecided

[tex]Undecided = \frac{9}{250}*6000[/tex]

[tex]Undecided = \frac{9*6000}{250}[/tex]

[tex]Undecided = \frac{54000}{250}[/tex]

[tex]Undecided = 216[/tex]

A dot plot, also known as a strip plot or dot chart, is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis. These types of charts are used to graphically depict certain data trends or groupings.

According to the given data

The total number of students in Gina's after-school program is 15 students.

Now,

The number of students who have 4 or more siblings is = 3+1 = 4

Answer:

0.15% of the students spent more than 557 on textbooks in a semester

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 473

Standard deviation = 28

According to the standard deviation rule, almost 0.15% of the students spent more than what amount of money on textbooks in a semester?

99.7% of the measures are within 3 standard deviations of the mean, so 100 - 99.7% = 0.3% are more than 3 standard deviations from the mean.

The normal distribution is symmetric, which means that 0.3%/2 = 0.15% spend less than 3 standard deviations below the mean, and 0.15% spend more than 3 standard deviations above the mean.

473 + 3*28 = 473 + 84 = 557

0.15% of the students spent more than 557 on textbooks in a semester

Answer:

145

Step-by-step explanation:

Each triangular side is 30ft

bottom is a 5*5 so it 25ft

30*4(#of sides)=120

120+25(bottom)=145

Answer:

I will give you the easy explanation here, go down there though to get a more complexed explanation and answer. Seeing it is a triangle, you can not multiply the 12 by 5. You have to multiply it by 2.5 because it dips in (because it's a triangle). Now you multiply the 5x5 to get 25. Now we have 25 for the base and 30 for each side. 30x4 to represent each side and add 25 for the base to get 145 as the final answer.

Step-by-step explanation:

Ok, they made this really easy with the 5's. You multiply the 5 by the 5 to get 25 in which the 12 there is about half of that, that made things really easy. Since the 12 goes to the middle that means that we can take what is from the middle to the side removing the half there getting you -2. Therefore, 12-2=10. Meaning the center is 10.

Answer:

[tex]y=-7x-2[/tex]

Step-by-step explanation:

We can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

Let (-1, 5) be (x₁, y₁) and our slope m is -7. By substitution:

[tex]y-(5)=-7(x-(-1))[/tex]

Distribute:

[tex]y-5=- 7 x - 7[/tex]

Adding 5 to both sides gives us our equation:

[tex]y=-7x-2[/tex]

Answer:

25

Step-by-step explanation:

i think you mean +10x

but (x+a)^2 = x^2 + 2ax + a^2

2ax = 10x

ax = 5x

a = 5

so (x+5)^2 = x^2+10x+25

Answer:

Around 300 Miles

Step-by-step explanation:

Nots sure of the exact number. If 28% of the trip is 101 miles then 50% would be around 210 miles.

So the entire trip as a whole should be near 300 miles.
