Answer:
Step-by-step explanation:
irrational roots always occur in pairs.
Other root is also irrational and is negative of first zero.
The MAD for City 1 is 24.
The MAD for City 2 is 11 1/3.
The MAD for City 2 is less than the MAD for City 1, which means the average monthly temperatures of City 2 vary less than the average monthly temperatures for City 1.
Step-by-step explanation:
your going to distribute the 2 to the x and the four your equation will then become (2x-8)=-5 you would then do the opposite of subtraction which is add so add +8 to the -8 and that cancels it out then you would +8 to the -5 and get 2x=3 then I'm confused from there hope that helps kinda
S= a(1-r ⁿ) /(1-r) & when r is < 1 & n →∞, the sum becomes S= a/(1-r)
Progression P is 2,1, 1/2,1/4,.. ==> r = 1/2
Sum of P when n--> ∞ = 2/(1-1/2) ==> S =4
Progression Q is 3,1,1/3,1/9,....==> r = 1/3
Sum of Q when n--> ∞ = 3/(1-1/3) ==> S =4.5
GIVEN THAT 4, 9/2 & X (to be calculated later is a geometric Progression, hence 9/2 - 4 = 0.5 =d (common difference , so X = 4.5+0.5 & X = 5
Sum of R =5 Then => 5= 4 /(1-r) & r=1/5
Then the sum of R = 4/(1-1/5) ==> S of R =5
Answer:
a. Ordinal
b. 66.67%
Step-by-step explanation:
a. Classifying students by grade year is a way of grouping them in order even though the quantitative difference between groups is unknown. This is an example of an Ordinal level of measurement.
b. There are 14 freshmen and 18 sophomore out of the 48 students. The percentage of students that are either freshmen or sophomore is:
