marishachu [46]

Answer:

(5.2591, 9.3531)

Step-by-step explanation:

given that the International Air Transport Association surveys business travelers to develop quality ratings for transatlantic gateway airports.

Ratings are from 1 to 10

the readings are

7 7 3 8 4 4 4 5 5 5 5 4 9 10 9 9 8 10 4 5 4 10 10 10 11 4 9 7 5 4 4 5 5 4 3 10 10 4 4 8 7 7 4 9 5 9 4 4 4 4

Mean = 7.3061

Std deviatin = 7.3100

Std error = $\frac{7.310}{\sqrt{49} } \\=1.0443$

95%,confidence interval = $7.3061 ±2.047 \\=(5.2591, 9.3531)$

Callie is comparing the costs of two options for her college education.

Ainat [17]

Answer:

Callie's comparison of two options for college education

The true statement is:

She would save $11,300 by choosing option A.

Step-by-step explanation:

Cost Analyses:

Option A: Community College + University Total Expenses

Tuition & Fees $5,800 ($2,900 x 2) + $19,000 ($9,500 x 2) = $24,800

Scholarships ($1,600) ($800 x 2) + ($20,000) ($10,000 x 2)=($21,600)

Room & Board $2,500 ($1,250 x 2) + $23,000 ($11,500 x 2) = $25,500

Work-Study + ($4,000) ($2,000 x 2) = ($4,000)

Total Cost $6,700 + $18,000 = $24,700

Option B: 4 years' University

Tuition & Fees $38,000 ($9,500 x 4)

Scholarships ($40,000) ($10,000 x 4)

Room & Board $46,000 ($11,500 x 4)

Work-Study ($8,000) ($2,000 x 4)

Total Cost $36,000

Difference between the two options = $11,300 ($36,000 - $24,700

A plastic bin contains red, yellow, and green key chains. Out of 350 key chains, 10% percent are yellow. Of the remaining key ch

Ulleksa [173]

Hello there! Thank you for asking your question here at Brainly! I will be assisting you with answering this question, and will be teaching you how to handle it on your own in the future.

We have 350 total keychains, in which 10% are yellow, 3/5 are green, and x are red. We will be solving for red, but we need to subtract 10% and 3/5 from 350.

So, let's find out how much 10% of 350 is.
Since 10% is equivalent to 1/10, we can divide 350 by 10 to find how many yellow key chains there are.
350 / 10 = 35.
There are 35 yellow key chains. We can subtract this from 350 to narrow it down.
350 - 35 = 315.

Now, let's find how much 3/5 of 350 is, and subtract it from our new number (315).

Divide 350 by 5, and then multiply that quotient by 3.
350 / 5 = 70.
70 x 3 = 210.

We have 210 green key chains. Now let's subtract that from 315. This will give us the remaining key chains - which are red.
315 - 210 = 105.

There are 105 red key chains.

I hope this helps!

Write the standard equation of a circle that passes through (-5 5) with center (-10 -5) brainly

timama [110]

Answer:

The equation of the circle is (x + 10)² + (y + 5)² = 125 in standard form

Step-by-step explanation:

* lets study the standard form of the equation of a circle

- If the coordinates of the center of the circle are(h , k) and its radius

is r, then the standard equation of the circle is:

(x - h)² + (y - k)² = r²

* Now lets solve the problem

∵ The coordinates of the center of the circle are (-10 , -5)

∵ The standard form of the equation is (x - h)² + (y - k)² = r²

∵ h , k are the coordinates of the center

∴ h = -10 , k = -5

∴ The equation of the circle = (x - -10)² + (y - -5)² = r²

∴ The equation of the circle = (x + 10)² + (y + 5)² = r²

- To find the value of the radius lets use the point (-5 , 5) to

substitute their coordinate instead of x and y in the equation

∵ The circle passes through point (-5 , 5)

∵ (x + 10)² + (y + 5)² = r²

- Use x = -5 and y = 5

∴ (-5 + 10)² + (5 + 5)² = r² ⇒ simplify

∴ (5)² + (10)² = r²

∴ 25 + 100 = r²

∴ r² = 125

* Now lets write the equation in standard form

∴ (x + 10)² + (y + 5)² = 125

* The equation of the circle is (x + 10)² + (y + 5)² = 125 in standard form
