Answer:

length between is <u>8</u><u>.</u><u>5</u><u>4</u><u> </u><u>units</u>

Step-by-step explanation:

Formular:

{ \bf{ =  \sqrt{ {(x_{1} - x_{2}) }^{2}  +  {(y_{1}  - y_{2}) }^{2} } }}

x1 is -4

x2 is 4

y1 is 4

y2 is 1

=  \sqrt{  {( - 4 - 4)}^{2} +  {(4 - 1)}^{2}  }  \\  =  \sqrt{64 + 9}  \\  =  \sqrt{73}  \\  = 8.54 \: units

Answer:

Distance = 8.25 units

Step-by-step explanation:

use the formula :

√ (x2 _ x1) + (y2 - y1)

where ,

x2 = 4

x1 = -4

y2 = 1

y1 = -1

SOVA2 [1]

Answer:

The true statement about Kendra's sample is:

b) Kendra's samples are precise but not accurate.

Step-by-step explanation:

a) Data and Calculations:

Average age of dogs currently alive = 4.8 years

Average ages of dogs in Kendra's sample

Week   Average Age (in years)

1                    3.7

2                   3.8

3                   4.2

4                   4.1

5                  3.9

6                  3.9

7                  4.0

Total         27.6

Mean = 3.9 (27.6/7)

b) Accuracy refers to how close Kendra's sample mean age of dogs is to the average age value as stated in the Modern Dog Magazine.  While the Magazine stated an average age of 4.8 years, Kendra's sample produced a mean of 3.9 years.  On the other hand, precision refers to how close Kendra's sample measurements are to each other.  With a mean of 3.9 years, the sample measurements are very close to each other.  Therefore, we can conclude that "Kendra's samples are precise but not accurate."

On the day that Ramon is born, his grandfather deposited $5000 for him in a certificate of deposit paying 10% interest compounde
kkurt [141]

The time required to get a total amount of $1,000,000.00 with compounded interest on a principal of $5,000.00 at an interest rate of 10% per year and compounded 1 times per year is 55.59 years.

<h3>Given data</h3>

Principal = $5,000

Rate = 10%

Final Amount A= $1,000,000

Time = ?

First, convert R as a percent to r as a decimal

r = R/100

r = 10/100

r = 0.1 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(1,000,000.00/5,000.00) / ( 1 × [ln(1 + 0.1/1)] )

t = ln(1,000,000.00/5,000.00) / ( 1 × [ln(1 + 0.1)] )

t = 55.59 years

(about 55 years 7 months)

Margaret [11]
Question:

width?

Solution:
Perimeter = 22
2(l + w)     = 22
2(5+w+w) = 22
2 (5 + 2w) = 22
     5 + 2w = 11
           2w = 6
             w = 3
