Answer:
Jane invested $37,000 in Fund B.
Step-by-step explanation:
Let;
IA = Amount invested in Fund A = $6,000
IB = Amount invested in Fund B = ?
PA = Amount of profit from Fund A = IA * 8% = $6,000 * 8% = $480
PB = Amount of profit from Fund B = IB * 2%
Therefore, we have:
Total profit = PA + PB = $1220 ........................ (1)
Substitute the relevant values into equation (1) and solve for IB, we have:
$480 + (IB * 2%) = $1220
IB * 2% = $1220 - $480
IB * 2% = 740
IB = 740 / 2%
IB = $37,000
Therefor, Jane invested $37,000 in Fund B.
Answer:
Step-by-step explanation:
You would require the table with the number of males and females who prefer either pink or yellow lemonade at the state fair.
Pink Lemonade Yellow Lemonade TOTAL
Male 156 104 260
Female 72 48 120
TOTAL 228 152 380
P(pink lemonade | female) = 72 / (48 + 72) = 72 / 120 = 0.6
P(pink lemonade) = (156 + 72) / (156 + 72 + 104 + 48) = 228 / 380 = 0.6
Therefore, The event "prefers pink lemonade" and "female" are independent because P(pink lemonade | female) = P(pink lemonade) = 0.6
