Answer:
yes, ±2
Step-by-step explanation:
The x-intercepts are found by setting y=0 and solving for x:
x^2/4 = 1
x^2 = 4
x = ±√4
x = ±2
The x-values of interest are -2 and +2.
First find out how much the 4 volleyball nets are by using 4*28 which would equal to 112. Now subtract 112 from 250 and that leaves you with 138. Then you divide 138 by 7 which will give you about 19.7 which you need to take all decimals out since it isn’t an whole number. The gym teacher can only buy 19 volleyballs.
Step-by-step explanation:
2(3x-5)=5x-3
6x -10 =5x -3
x=7
Use Pythagoras theorem. (a^2 + b^2 = c^2)
300^2+300^2 = 180000
√180000 = 424.3
The answer is 424 foot.
Hope this helps.
Answer:
D)The experimental probability is greater than the theoretical probability
Step-by-step explanation:
Given:
75 times a die is rolled out of 39 times it got 6
To Find :
Which statement is true?
Solution:
The theoretical probability is given by the ,
Pt=No.of favorable outcomes/Total outcomes
Here favorable is getting 6 on the die
so how many times we can get 6 =1 time
Total outcomes =6
Pt=1/6
Pt=0.1667
Now for
The experimental Probability ,
Pe=Number times that event occur /Total no of trails
Here 39 times we get 6 and total no trails are 75
Pe=39/75
Pe=0.52
Hence we can say that Pe>Pt.
