Answer:
number 4: frequency 8
number 5; frequency 2
Step-by-step explanation:
The mean of all rolls is their sum divided by their number, which is 30. Let x and y represent the number of rolls of 4 and 5, respectively. Then the mean is ...
(1×6 +2×3 +3×5 +4x +5y +6×6)/30 = 3.5
This simplifies to ...
(6 +6 +15 +4x +5y +36) = 3.5×30 . . . . . multiply by 30
4x +5y = 42 . . . . . . subtract 63
Of course, the total number of rolls must be 30:
6 +3 +5 +x +y +6 = 30
x + y = 10
We can solve this system of equations by substitution, using x=10-y:
4(10 -y) +5y = 42
40 +y = 42
y = 2
x = 10 -2 = 8
The two missing numbers are 8 and 2. The frequency of 4 is 8; the frequency of 5 is 2.
Answer:
10
Step-by-step explanation:
The given is a special right triangle with angle measures as follows:
45-45-90
The side lengths for this special right triangle are represented as follows:
a (the side length that sees angle measure 45)
a (the side length that sees angle measure 90)
İn the image we can see that one of the side length that sees angle measure 45 is 10
so c, the side length that sees angle measure 90 (hypotenuse),
is equal to
10
Answer:
