Answer:
0.11
Step-by-step explanation:
Let the random variable score, X = 26; mean, ∪ = 19.6; standard deviation, α = 5.2
By comparing P(0≤ Z ≤ 26)
P(Z ≤ X - ∪/α) = P(Z ≤ 26 - 19.6/5.2)
= P(Z ≤ 1.231)
Using Table: P(0 ≤ Z ≤ 1) = 0.39
P(Z > 1) = (0.5 - 0.39) = 0.11
∴ P(Z > 26) = 0.11
We know that
surface area=2*[area of the base]+perimeter of the base*height
find the area of the base
is an equilateral triangle
b=15/3----> 5 in
applying the law of sines to find the area
Area=(1/2)*b²*sin 60°------> area=(1/2)*5²*sin 60°----> 10.8253 in²
alternative method to find the area of the equilateral triangle
find the h value
applying the Pythagoras theorem
h²=5²-2.5²-----> h=√18.75-----> h=4.33 in
area=b*h/2----> area=5*4.33/2----> 10.8253 in²
surface area=2*[10.8253]+15*4-----> 81.65 in²
the answer is
81.65 in²
her brothers's ages are 3 year old and 5 year old.
Jeanna is four years older than the sum (5 + 3) of her brothers.
Let jeanna = j, set the equation:
j = 5 + 3 + 4
Simplify
j = 8 + 4
j = 12
12 years old is your answer
