Answer:

1. and III.

Step-by-step explanation:

Option 1 and 3 are correct.

The probability of landing on heads would be 1/2, so 50 times in 100. This is the expected outcome, so option 1 is correct.

However, that is just the most probable outcome, probability is almost never 100% accurate. Therefore, the number of heads will most likely be 50, give or take 5 or so. Therefore, option 3 is also correct.

Answer:

a) $(f\ has\ a\ relative \ minimum \ at\ x_{0} )$ ∧ $(f\ is\ differenciable\ at\ x_{0} )$ ⇒ $f^{'} (x_{0} )=0$ .

b) $(n\ is\ prime)$ ⇒ $(n=2)$ ∨ $(n\ is \ odd)$ .

c) $R\ is \ irreflexive\$ ⇒ $(R\ is\ symmetric)$ ∧ $(R\ is\ transitive)$ .

d) $detB=0$ ⇒ $(B \ is\ square)$ ∧ $(B\ is\ not\ invertible)$ .

e) $f\ has\ a\ critical\ point\ at \ x_{0}$ ⇔ $(f^{'}(x_{0})=0)$ ∨ $() \ f^{'}(x_{0}) \ does\ not\ exist$ .

f) $2n$ ∨ $n>4$ ⇒ $2$ .

g) $6\geq n-3$ ⇔ $n>4$ ∨ $n>10$ .

h) $x \ is \ cauchy$ ⇒ $x\ is\ convergent$ .

i) $\lim_{x \to \ x_{0}} f(x)=f(x_{0})$ ⇒ $f\ is\ continous\ at \ x_{0}$ .

j) $(f\ is\ diferenciable\ at\ x_{0})$ ∧ $(f\ is\ increasing\ at\ x_{0})$ ⇒ $f^{'}(x_{0})>0$ .

Which statement describes the key difference between a traditional IRA and a Roth IRA?

scZoUnD [109]

"Traditional IRA contributions are made with pretax dollars, while Roth IRA contributions are made with after-tax dollars" statement describes the key difference between a traditional IRA and a Roth IRA.

Option: D

A traditional IRA that is an individual retirement account enables investors to channel pre-tax income into assets that can increase tax postponed. Donations to a traditional IRA might be tax deductible focusing on the earnings, tax filing record and other considerations of the taxpayers.

A Roth IRA is a tax-favored retirement savings account that enables you to tax-free withdraw your savings. These are sponsored with after-tax dollars; tax-deductible investments are not. But the cash is tax-free until one begin withdrawing funds.
