An internet company randomly selected 50 of its customers and asked them how many hours per week they use the internet. Of those

surveyed, 28 use the internet more than 15 hours per week. Based on the data, if the company has 800 subscribers, how many use more than 15 hours per week?

Answer:

Number of person use more than 15 hours per week from 800 subscribers = 448

Step-by-step explanation:

Given:

Total number of sample = 50

Result = 28 Person use more than 15 hours per week

Find:

How many people use more than 15 hours per week

Computation:

⇒ Probability of Person use internet more than 15 hours per week = 28 / 50

⇒Probability of Person use internet more than 15 hours per week = 0.56

⇒Number of person use more than 15 hours per week from 800 subscribers = 800 × Probability of Person use internet more than 15 hours per week

⇒Number of person use more than 15 hours per week from 800 subscribers = 800 × 0.56

⇒ Number of person use more than 15 hours per week from 800 subscribers = 448

The upper-left coordinates on a rectangle are (-5, 6)(−5,6)left parenthesis, minus, 5, comma, 6, right parenthesis, and the uppe
sammy [17]

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question.

The upper-left coordinates on a rectangle are (−5,6) and the upper-right coordinates are (−2,6). The rectangle has a perimeter of 16units. Draw the rectangle on the coordinate plane below.

If the coordinates of the top of the triangle (breadth) is  (−5,6) and  (−2,6), we can calculate the breadth of the rectangle by taking the difference between the two points using the formula:

D = √(y₂-y₁)²+(x₂-x₁)²

Given x₁ = -5, y₁= 6, x₂ = -2 and y₂ = 6

D = √(6-6)²+(-2-(-5))²

D = √0²+3²

D = √9

D = 3 units

Breadth = 3 units

Given the Perimeter to be 16 units and the formula for calculating the perimeter of rectangle t be P = 2(L+B), we can get the length of the rectangle.

16 = 2(3+L)

16 = 6+2L

16-6 = 2L

2L = 10

L = 10/2

L = 5 units.

<em>Hence the length of the rectangle is 5 units and the breadth is 3 units. Find the diagram in the attachment.</em>

Kara travels at a constant speed of 72 miles per 2 hours. At this rate, how far does she travel after 6.5 hours?
dybincka [34]

Answer:

234 hours

Step-by-step explanation:

To find the miles per hour, divide 72 by 2 and that equals 36. So 36 miles every hour. So then do 36 × 6 which equals 216. So this is 216 miles in 6 hours, but you still need 0.5 of an hour, so to find how far she travels in 0.5 of an hour, divide the amount she travels in one hour by two. So 36 ÷ 2 which equals 18. So she travels 18 miles every 0.5 of an hour. Then add 18 to the 216 which equals 234.

Hope This Helps!!!

What is the 399,713 rounded to the place value of the third underlined digit of 399
maksim [4K]

The <em>correct answer</em> is:

400,000.

Explanation:

The third digit in 399 is 9. To round to this place value, we inspect the digit behind it. If the digit is 5 or greater, we round up; if it is less than 5, we round down.

The digit behind 9 is 7. Since it is greater than 5, we round up. This would ordinarily put the number up 1; however, doing that makes the 9 a 10, which in turn makes the next number 10, and the next number 4. This gives us 400,000.

How does the graph of g(x) = (x - 3)^3 + 4 compare to the parent function f(x)=x^3 ?​
masha68 [24]

Answer:

f(x) has moved:

4 units in the positive y direction i.e upwards

3 units in the positive x direction

Step-by-step explanation:

to get g(x), f(x) has undergone the following transformations

f(x) = x³

f1(x) = x³ + 4      (translation of 4 units in the positive y direction i.e upwards)

f2(x) = g(x)  = (x-3)³ + 4 (translation of 3 units in the positive x direction i.e towards the right)
