Answer:
Juan invested $ 11,800 in Fund A and $ 7,200 in Fund B.
Step-by-step explanation:
Given that Juan invested $ 19000 in two mutual funds, and Fund A earned 7% profit during the first year, while Fund B earned 3% interest, if he received a total of $ 1042 profit, to determine how much she had invested in each mutual fund the following calculation must be performed:
19000 x 0.07 + 0 x 0.03 = 1330
15000 x 0.07 + 4000 x 0.03 = 1170
11000 x 0.07 + 8000 x 0.03 = 1010
11500 x 0.07 + 7500 x 0.03 = 1030
11800 x 0.07 + 7200 x 0.03 = 1042
Therefore, Juan invested $ 11,800 in Fund A and $ 7,200 in Fund B.

Answer:
a-b b-50%
Step-by-step explanation:
Let X be the answers all 48 questions on a multiple-choice test by guessing.
<span>p = 1/4 </span>
<span>q = 1 - 1/4 = 3/4 </span>
<span>n = 48 </span>
<span>μx = n*p = 48*(1/4) = 12 </span>
<span>σx = sqrt(n*p*q) = sqrt(4/*(1/4)*(3/4)) = 0.8660254038 </span>
<span>P(X = 15) = P(X ≤ 16) - P(X ≤ 14) = P((X - 12)/0.8660254038 ≤ (16 - 12)/0.8660254038) - P((X - 12)/0.8660254038 ≤ (14 - 12)/0.8660254038) = P(Z ≤ 4.62) - P(Z ≤ 2.31) = 1 - 0.9896 = 0.0104 </span>
<span>You could use the binomial distribution: </span>
<span>P(X = 15) = 0.07670882173 </span>
<span>(48) </span>
<span>(15)*((1/4)^15)*(3/4)^33 = 0.07670882173</span>
