Step-by-step explanation:
add all the freqency up which is 100
you have to use a customize spinner and put in all the colors that are all on the side...
Spin 150 times ( 250-100= 150) and put tally marks on the sheet of tallys.
Then count all you red and see.
Hope all that makes sense..
Answer:
3 student.
Step-by-step explanation:
From the first statement:
Let the total score be T
Let the total number of student be x
The average of the score = 72
Average = Tota score / number of student
72 = T/x
Cross multiply
T = 72x ..... (1)
Second statement:
One more student took the test and the average becomes 76 with the student having a score of 88.
Therefore,
Overall score = T + 88
Total student = x + 1
Average = 76
Average = overall score / total number of student
76 = (T + 88) /(x + 1)
Cross multiply
76(x + 1) = T + 88
Clear bracket
76x + 76 = T + 88
From equation 1
T = 72x
76x + 76 = 72x + 88
Collect like terms
76x – 72x = 88 – 76
4x = 12
Divide both side by the coefficient of x i.e 4
x = 12/4
x = 3
Therefore, the initial number of the student were 3.
There are 6 of them in all. In the order given, are the numbers they receive.
16 x 6 = 96
At first, each of them receives the same amount of stickers, 16, which, when multiplied with the amount there is, equals 96.
This leaves 4 left.
In the order starting from the first (Aaron), it is:
Aaron, Cathy, Esther, Ginny, etc
Ginny is the person to receive the last sticker
hope this helps
Y intercept (x = 0)
4(0)+3y=12
3y = 12
y = 12/3
y = 4
X intercept (y = 0)
4x+3(0)=12
4x = 12
x = 12/4
x = 3
R/ The intercept with x is (3,0) and with y (0,4)
Answer: the answer is 0.04
