Answer:

a₂₀ = 77

Step-by-step explanation:

There is a common difference between consecutive terms , that is

5 - 1 = 9 - 5 = 13 - 9 = 4

This indicates the sequence is arithmetic with nth term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 1 and d = 4 , then

a₂₀ = 1 + (19 × 4) = 1 + 76 = 77

Center: (2,8), Radius: 3
Rzqust [24]

Answer:

I’m not sure what this question is asking, but I’ll write an equation of this circle you are describing. Here, the x coordinate of the center is h, the y coordinate is k, and radius is r in the equation : (x-h)^2+(y-k)^2=r^2, meaning the equation in this situation is the following: (x-2)^2+(y-8)^2=9

3. What is the Median Average of Shoe Sizes from the data set below?
oksano4ka [1.4K]

Answer:

10

Step-by-step explanation:

Hi!

We first need to order the numbers in the sequence in ascending order:

6.5,\:7,\:7.5,\:9,\:9,\:10,\:11,\:12.5,\:13,\:13,\:13

<em>The median is the middlemost number(s) in a sequence.</em>

<em />

In that case, we can see that \boxed{\boxed{10}} is the median.

More info:

Since there are 11 terms, we will divide by two. 11 ÷ 2 = 5.5. Since we round up from 5, we will count over 6 terms.

In doing so, we can see that 10 will remain our answer.

Hope this helps!

Banerjee Inc. wants to maintain a target capital structure with 30% debt and 70% equity. Its forecasted net income is $825,000,
bulgar [2K]

The capital budget will be supported with 30% debt and 70% equity. Since the company's income will be $825,000 this is the maximum equity that can be put towards the capital budget and therefor is matched in the ratio 70:30 by borrowings. If $825000 is 70%, divide that (825,000/.70) you’ll get the total maximum budget of $1,178,571 which is letter c. To get the 30%, just deduct the $825,000 to $1,178,571, you’ll get $353,571. To make sure your answer is correct, add up the 70% and 30% values and if they make the original total value, then the answer is correct. $825,000 + $353,571 = $1,178,571
