Answer:
.74
Step-by-step explanation:
First, you know that 30% are boys and 70% are girls. Then, take 60% of 30% and 70% of 80%. From there you get .74 as the probability of a randomly chosen child having taken a car to school.
mean=the average of the numbers calculated. median=the number in the middle. mode=the numbers that appear most often
Answer:
Arc YX = 104°
Step-by-step explanation:
Arc YX + Arc YZ + Arc XZ = 360° (full circle = 360°)
Substitute
Arc YX + 110° + 146° = 360°
Arc YX + 256° = 360°
Arc YX = 360° - 256°
Arc YX = 104°

Step-by-step explanation:
X=the missing value
the median is the middle number, but in this case there are two which happens to be 25 and x
so the formula is
25+x/2=31.5
use algebra to solve
25+x=63
x=63-25
x= 38
Therefore, the missing value is 38.
