b.) 4
Step-by-step explanation:
a.) After looking at the age in years collum you can notice that all of ages have a difference of 2. With this you can infer that the missing number is 28.
b.) To find the mean add up all the numbers in the frequency column.
3+2+7+8+0=20
Divide that by the amount of numbers. There are 5 numbers so 20/5=4.
Hope this helps!
Answer:
x= 2
Step-by-step explanation:
so we have the height of this scalene triangle
formula for area of a scalene triangle is K=bh/2
K=area (4)
4=b4/2
solve for b
multiply by 2 on both sides
8=b4
divide by 4
2=b
check your answer 4=2(4)/2
4=8/2
4=4
statement is true
