Answer:
Probability = 1/5
Step-by-step explanation:
Total ways of arrangement for 10 students = 10 !
Ways to arrange 2 students consecutively & other 8 students = 9 ! x 2
( As 9! to arrange 9 units, as 2 considered together ; & 2 for arranging 2 consecutive students - respectively )
So, Probability = Favourable outcomes / Total outcomes
= ( 2 x 9! ) / 10! = ( 2 x 9 x 8 x ..... 2 x 1 ) / 10 x 9 x ....... 2 x 1)
= 2 / 10 = 1/5
Answer:
y = 5x + 4
Step-by-step explanation:
First I found the slope by using the the definition that slope is rise/run so I saw that the y value went up from 4 to 9 which is 5 units and then the x value went up one in that same time. This means that the slope is 5/1. Then I found the y intercept by seeing where x = 0. On the graph you can see the line touches the y - axis at a value of 4 which means that the y - intercept is 4. Plugging these values into the y = mx + b equation you get y = 5x + 4.
Total of 25 cakes
Tina : placed 0.24.....24%
Dora : placed 9 out of 25.....9/25 = 36%
Wilson : placed 20%
Kane: placed the remainder ...100% - (24% + 36% + 20%) = 20%
Dora placed the most
You would do 7/8 x 8/1 which is 56/8 which simplifys to 7 so your answer would be 7
