Answer:
(x+6)^2 + (y-8)^2 = 10^2
or
(x+6)^2 + (y-8)^2 = 100
Step-by-step explanation:
Equation of a circle in standard form: (x-h)^2 + (y-k)^2 = r^2
(h,k) represent the center of the circle
h = -6
k = 8
r = the length of the radius
10^2 = 100

the Pearson product moment correlation measures the linear relationship between two interval- and/or ratio-scaled variables (scale variables) such as those depicted conceptually by scatter diagrams: True.
What is Pearson product moment correlation?A measure of the degree and direction of relationship between two variables assessed on at least an interval scale is the Pearson product-moment correlation coefficient, or Pearson's correlation.
If you want to determine whether there is a linear relationship between two quantitative variables, you may use Pearson's correlation. The expectation of a linear relationship between those variables is the sole part of the study hypothesis.
This approach finds the precise amount or degree of correlation between any two variables and tells if there is or is not any correlation between them.
Thus, the given statement is true.

Tiny's Tattoo Parlor sold 389389 tattoos this month. 4343 of those tattoos were arm tattoos. Based on this data, what is a reasonable estimate of the probability that the next customer does not get an arm tattoo?
If the parlor sold 389389 tattoos and 4343 were arm tattoos, then the probability of next customer does not get an arm tattoos is 0.99
Total number of tattoos sold in this month = 389389 tattoos
Number of arm tattoos = 4343
Number of other tattoos = 389389 - 4343
= 385046
The probability = Number of favorable outcomes / Total number of outcomes
Substitute the values in the equation
The probability of next customer does not get an arm tattoos = 385046 / 389389

The fracion 12k⁸/4(k⁵)² expressed in its simplest form is the expression 3/k².
How to simply the expression in fractionTo simplify fraction, we need to factorise the denominator and numerator, and then look for common factors in the numerator and denominator and cancel.
Given the fraction;
12k⁸/4(k⁵)² = 3 × 4 × k⁸/k² × 4 × k⁸ {expressed to get a common factor}
12k⁸/4(k⁵)² = 3 × 4k⁸/k² × 4k⁸
4k⁸ is a common factor to the numerator and denominator, so we cancel it out

A rectangle has an area of 943 square feet. Its width is five feet less than twice the length. Find the measures
of the length and width of the rectangle.
Answer: the rectangle is 23 x 41

x = length
2x - 5 = width
A = length x width = (x)(2x-5) = 943
2[tex]x^{2}[/tex] - 5x - 943 = 0
use quadratic equation to solve for x:
a = 2, b = -5, c = -943
