Answer:
The answer is 1…
Step-by-step explanation:
Well you can elimate a lot of fractions right off the bat just multiply everything by 60/1.
the final result will be
(240+15+40)+ (300+90-72)- (360+105+24)
Now solve
240-15+40=265
300+90-72=318
360+105+24=513
265+268-489
265+268= 11
533-513=20
bleh i m not sure naymore
The probability that Nins goes 0 days is 0.2, the probability that she goes 1 day is 0.50, and the probability that she goes 2 days is 0.30. You can write these data as a table:
where are numbers of days and are probabilities.
The expected value of the number of days per week on which Nina goes to the supermarket is
.
Answer: the expected value of the number of days per week on which Nina goes to the supermarket is 1.1.
Im assuming it would be 60 or 60.375(Work below)
Because usually when it says "out of" it means divide so i divided 8 from 21 and got 2.625 so then i took the 63 and subtracted 2.625 from that and got 60.375 so its either 60 or 60.375 again im not sure if im wrong im very sorry.

Answer:
C. 168
Step-by-step explanation:
One of the more useful approaches to multiple choice problems is eliminating the answers that don't make any sense.
You know a square has internal angles of 90 degrees, and that polygons with more sides have larger angles. No internal angle can be more than 180 degrees in a regular polygon. The only answer choice in this range is the correct one:
C. 168
Answer:
a)It is a vertical line with an undefined slope
b)It is a vertical line with an undefined slope
c)7/4
d)-7/4
Step-by-step explanation:
The formula for gradient of a line is given as;
m=Δy/Δx
where Δy = y₂-y₁ and Δx=x₂-x₁
<u>For L₁ </u>
x=2
It is a vertical line with an undefined slope
<u>For L₂</u>
x=-3
It is a vertical line with an undefined slope
<u>For L₃</u>
The points on the line are : (0,-3) and (4,4)
m= Δy/Δx
m= 4--3/4-0
m=7/4
<u>For L₄</u>
The points on the line are : (0,-3) and (-4,4)
m=Δy/Δx
m=4--3/-4-0
m=7/-4
m= - 7/4
