Step-by-step explanation:
We are told that for a large data set of a average student grades, the third quartile Q3 is found 78.5.
Since we know that third quartile represents the number such that 75% of the data is less than this number. Third quartile is the middle value between median and the highest value of a data set. Third quartile is also known as upper quartile. Third quartile splits lower 75% data from highest 25% of data.
Therefore, third quartile represents that 75% of student grades are less than 78.5 and 25% of students grades are greater than 78.5.
Answer:
2/9
12.5%, 30% ,45%
Step-by-step explanation:
Possible outcomes
W = wild
S = sandy shores
G = green hills
W6 W7 W10
S6 S7 S10
G6 G7 G10
There are 9 outcomes
2 are over a week without hills (W10 and S10) and
P(10 days not at hills) = # more than 7 days no hills/total
=2/9
We need all the numbers in the same form, I will change to decimal
1/8 = .125
30% = .30
.45
Smallest to largest
.125 <.30 <.45
1/8 < 30% < .45
Changing to percent form
12.5%, 30% ,45%
Answer:
Step-by-step explanation:
The first 2 do sum up to 180 degrees, so the first 2 ARE triangles, but i cant see the full question of the 3rd and 4th one.
3/4 - 3/5 first we need to change it to the same denominator so it’ll be
15/20- 12/20 which equals 3/20
