60 divided by 4.
EXPLANATION:
If his grandfathers age is 3 more than whatever 4 times seans age is. we can do 63 - 3. which is 60.
Then you fond seans age. 60 divided by 4 is the equation to find seans age.
sry its a bad explanation but I hope the answer helps!

One direction
Hope this helps xx
Answer:
12
Step-by-step explanation:
A 2 - sided counter ; (red, yellow)
A spinner (1,2,3,4,5,6)
Number of trials = 80
P(red and number > 3) :
P(red) = 1/2 ;
P(number >3) : numbers greater Than 3 = (4, 5, 6)
Hence, P(number <3) = 3 /6 = 1/2
Theoretical probability = 1/2 *1/2 = 1/4
Expected number of outcomes :
1/4 * number of trials
1/4 * 80 = 20
Experimental outcome :
Relative frequency = number of outcomes / number of trials
Relative frequency = 2/5
Hence,
2/5 = number of outcomes / 80
Cross multiply :
160 = number of outcomes * 5
Number of outcomes = 160 /5 = 32
Actual outcomes = 32
Difference between actual and expected :
32 - 20 = 12
Answer:
26.25 square feet
Step-by-step explanation:
Calculation to determine the area of the seat
Using this formula
Area=1/2*(b1+b2)*h
Where,
b1=8 feet
b2=7 feet
h=3.5 feet
Let plug in the formula
Area=1/2*(8+7)*3.5
Area=1/2*15*3.5
Area=26.25
Therefore the area of the seat is 26.25 square feet
