Step-by-step explanation:
Hope this helps.
Given:
1 pack = 5 pencils and cardboard.
1 pack must be between 60 grams and 95 grams
60g < x < 95g ; where x represents 1 pack.
Card board: 15 grams.
95g - 15g = 80g maximum total weight of 5 pencils
80g / 5 = 16g maximum weight of a single pencil
60g - 15g = 45g minimum total weight of 5 pencils
45g / 5 =9g minimum weight of a single pencil
9 < x < 16 ; where x represents a single pencil in the pack.
Answer:
10. x= 10 y=sqrt 200
11. x=y=450
12. x=19 y=sqrt 1083
13. x=sqrt 48 y=sqrt 12
Step-by-step explanation:
10.
x and 10 are the same
10^2+10^2=200
sqrt 200 is not a whole number so y is just sqrt 200
11.
30^2=2x^2 because x and y are the same
x^2=450
sqrt 450 is not a whole number so x and y are just sqrt 450
12.
x= 38 divided by 2=19
38^2=19^2+y^2
1444=361+y^2
y^2=1083
sqrt 1083 is not a whole number so y is just sqrt 1083
13.
x^2=(x/2)^2+36=x^2/4+36
x^2=48
sqrt 48 is not a whole number so x is just sqrt 48
y is half of x so it is sqrt 12
Answer:
Step-by-step explanation: Let S represent the sample space , then the possible trials are: S= {SSS, FSSS, FFSSS, FFFSSS, FFFFSSS, …}
Y = the number of trials to be tested.
The possible values of Y are P ={x ∈N , x≥3}
Therefore the five smallest possible values of Y are :
1. Y{SSS} ........ 3 outcomes
2. Y{FSSS} ...... 4 outcomes
3. Y{FFSSS}....... 5 outcomes
4. Y{FFFSSS} ...... 6 outcomes
5. Y{FFFFSSS} ..... 7 outcomes
