Step-by-step explanation:
Let sum of observations be S and number of observations be n.
Average A=
The average height of 4 children is (15h-3)

Also, when two more children join the group with heights of (10h+46) centimeters and (14h-16) centimeters the sum of heights of 6 children will be

Now, Average height of 6 students=
At h=9
Average height of 6 students=
Step-by-step explanation:
V²= U² + 2as
V² - U²= 2as
Divide both sides of the equation by 2s
a= V² - U²/2s (a= square of V minus square of U all over 2s)
Answer:
If she made <u>2</u> <em>1/2</em> batches of muffins and you had 2/3 of raisins per 1 batch then you'd have a total of 1 2/3 cups of raisins
Step-by-step explanation:
1 batch= 2/3 cups
<u>2 batches</u>=4/3 cups or 1 and 1/3 cups
<em>1/2 batch</em>= 1/2 of 2/3= 1/3 cups
2 batches+1/2 batches= 1 and 1/3 cups+1/3 cups
1 and 1/3 cups+1/3 cups= 1 and 2/3 cups of raisins
Answer:
x=13
Step-by-step explanation:
3x+78 +x+50=180
3x+x+78+50=180
4x+128=180
4x=180-128
4x=52
4x/4=52/4
x=13
