Answer:
Anya's line has a slope of m = 3
Step-by-step explanation:
Explanation:-
Anya created a graph representing the line
(y−2)=3(x−1)
From this, we can deduce that the slope-intercept representation is
y = mx +c
Now by rewriting Anya's line
y−2=3(x−1)
⇒ y - 2 = 3x - 3
⇒ y = 3x - 3 + 2
⇒ y = 3 x - 1
<pBy comparing this with the slope-intercept structure<p y = mx +c<pwe conclude that Anya's slope is m = 3, and y-intercept is C = -1
Answer:black
Step-by-step explanation:
All prime numbers are odd with the exception of two. Hence, if we consider the sum of the first million primes, it consists of one even number combined with 999,999 odd numbers. Since the product of an odd number multiplied by another odd number results in an odd number, we conclude that the sum must be an odd number, being even + odd = odd.
It's clear that an odd number ends with an odd digit, so the only digit that can be eliminated is b (an even digit).
Solution
The number of weeks in a year is 52 weeks
In a typical year, where each flea treatment lasts 4 weeks, Jim's dog would receive
Conversely, during especially bad flea years, when treatments only last for 3 weeks, Jim's dog would need
So in a year, Jim's dog would need 17- 13 =4 extra treatments.
4 treatments at 3 weeks each total 4×3 =12 weeks of additional treatment
The formula to calculate the difference between two standard deviations of populations n1 and n2 is:
sigma (difference)=√(sigma1/n1 + sigma2/n2). For this scenario:
sigma(d)= √(49/100 + 36/50)
Thus, the calculated standard deviation of the difference equals 1.1.
