Answer:
Probability = 0.13591
Step-by-step explanation:
We are given;
Population mean; μ = 4.55
Population standard deviation: σ = 0.39
Now, we want to find the probability that the housefly's wing length will meet the requirements of the first phase of the experiment. This is;
P(3.77mm < X < 4.16mm)
Z-score formula is;
z = (x - μ)/σ
When x = 3.77mm
z = (3.77 - 4.55)/0.39
z = -2
When x = 4.16
z = (4.16 - 4.55)/0.39
z = -1
From online p-value calculator between 2 z-scores attached, we have;
P-value = 0.13591
Answer:
<h2><u>
60</u></h2>
<u>But the actual solution is 63.</u>
Step-by-step explanation:
<em>55+8=63</em>
<em>6</em><em><u>3</u></em>
<em>3<5 so you don't round up, you round down.</em>
Rounding down... 60
60
But the actual solution is 63.
To answer the question above, calculate the price per ounce of cereal of each local grocery stores
Save-Some-More $0.33 / ounce
Save-The-Most $0.28 / ounce
Spend-Less-Money $0.27 / ounce
Cheap-Food $0.3 / ounce
Thus, the final arrangement should be: (1) Spend - Less-Money, (2) Save-The-Most, (3) Cheap-Food, (4) Save-Some-More
3/(5 - 6i)
To simplify this, we need to multiply both sides by the conjugate of the denominator, which is 5 + 6i
3(5 + 6i)
Distributive property.
15 + 18i
(5 - 6i)(5 + 6i)
25 + 30i - 30i - 36i^2
25 - 36i^2
i^2 = -1
25 + 36
61
<h3><u>The simplified expression is (15/61) + (18i/61).</u></h3>
