Suppose that you flip a coin 13 times. What is the probability that you achieve at least 5 tails?

1 answer:

5 0

Heads, or tails. It's 1/2 a chance, because either way you will either land heads or tails. It would be a probability of 1-(1/2)^5. Can you solve that?

Answer:

See below

Step-by-step explanation:

If you just want the tip

$0.20*161.86\approx\frac{1}{5}*160=32$

If you want the total bill

$1.20*161.86\approx160+32=192$

What is 1/8 of a full rotation

Naya [18.7K]

Answer:

45°

Step-by-step explanation:

If we consider a full rotation to be 360°, we can simply divide 360 by 8 to find 1/8 of a full rotation.

360 ÷ 8 = 45

1/8 of a full rotation is 45°

Answer:

It would be D because X^2 is different from 3x you would just multiply X^2 by 1 and 3x by 1 to get x^2+3x

Evaluate the integral: dx / e^(pie*x) from 2 (upper bound) to 0.

kenny6666 [7]

Substitution:
u = - π x
d u = - π d x
d x = - d u / π
----------------------
$-1/ \pi \int\limits^2_0 {e ^{u} } \, du =- \frac{e ^{- \pi x} }{ \pi } = \\ -1/ \pi (e ^{-2 \pi } -1) = \\ = \frac{1}{ \pi } - \frac{1}{ \pi e ^{2 \pi } }$
