Answer:
a.) 26< a <u>28 </u>
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!
Multiply 1/5 and 26/1 across the top and bottom, and you get 26/5
From there, you can estimate that its a little more than 5 because you know that 25/5 is 5 and 26/5 should be a tiny bit greater.
Hope this helped!
Answer:
x/4
Step-by-step explanation:
x + 4/4 = y + 3/3

4y=3x + 12 -12
4y=3x
y/3 = x/4
