4(x÷9)=2
4 is multiplied to the (x÷9) to get your answer of 2
Answer:
20
Step-by-step explanation:
The expected value of a toss is:
E(X) = (0.10) (3) + (0.30) (1) + (0.60) (0)
E(X) = 0.6
If she scores an average of 0.6 points per toss, then the expected number of tosses needed to get 12 points is:
12 / 0.6 = 20
Using a random number table, we can assign digit 0 as a 3-point hole, digits 1-3 as a 1-point hole, and digits 4-9 as no points. Read the digits and add the points until you get 12 points. The number of digits read is the number of beanbag tosses.
Answer:
Median: 17
Q1: 10
Q3: 23
Step-by-step explanation:
2, 4, 9, 11, 12, 16, 18, 20, 22, 24, 28, 32
Median is middle number/average of the 2 middle numbers. 16 + 18 = 34/2 = 17
First/lower quartile/Q1 = middle of lower half of ordered data set
= 9 + 11 = 20/2 = 10
Third/upper quartile/Q3 = middle of upper half of ordered data set
= 22 + 24 = 46/2 = 23
Sorry if this is too late. Posting it will probably save someone else, though.
The interior angle measures are 900 degrees
131+122+125+148+107+126 = 759
900-759 =141
X = 141
Sin2x = 2 sinx cosx
so 12 sinx cosx = 6 sin2x Answer
