Tju [1.3M]

Answer:17.3964 males 7.6035 females

Step-by-step explanation:

The first way to calculate the expected uses the marginal percentages. If sex is not related to flavor preference, you would expect the same percentages of males to prefer the same flavors as females. Since overall 20.71% prefer vanilla, you would expect 20.71% of males to prefer vanilla. Now, 20.71% of 84 people is 17.3964, so this is how many males you would expect to prefer vanilla. You would also expect 20.71% of the females to prefer vanilla, which is 17.6035. So you'd expect 17.3964 males and 17.6035 females to prefer vanilla.

Jenny is a great saver! She has $80 in her savings account. She deposits $25 each week into her account. She wants to save at le
enot [183]

Answer:

80+25x\geq 300

Step-by-step explanation:

Since she already has 80$ in the account it will be the starting point.

To those 80$ she adds 25$/w.

Since the amount of week is what needs to be determined we'll refer to it as x.

So far we have 80 + 25x.

Now since she only wants to withdraw once she has at least 300$, it means that the amount has to be either equal to 300 or more than 300.

Which gives us 80+25x\geq 300
