In this question, you are given the number of dice faces(8 faces) and the number of the roll( 2 rolls then add 1 value). You are asked the average value.
First, you need to count the average value of the dice probability. Since the lowest possible is 1 and the highest possible is 8, then the dice average value would be: (1+8)/2= 4.5
Then, the average intelligence of the character would be : 2 dice +1 = 2(4.5) +1 = 10 intelligence
Answer:
The correct option is;
69 cm
Step-by-step explanation:
The z-score, or standard score is a measure of how far a data is from the mean
The z-score, is given by the relation;
Z = Standard score
x = Value observed
μ = The mean height of the plants = 52.5 cm
σ = Standard deviation = 7.2 cm
Given that the z-score = 2.25, we have;
Therefore, x = 7.2 × 2.25 + 52.5 = 68.7 cm ≈ 69 cm
Therefore, the minimum required height for this type of plant to be displayed in the main lobby is 69 cm.
The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h.
<span>A=<span><span>(<span>a+b</span>)</span>2</span>h</span>
Solve for a.
