These are the probabilities of each event

  • Flipping tails on each coin has a probability of 1/2, so the probability of 4 consecutive tails is \left(\frac{1}{2}\right)^4 = \frac{1}{16}
  • If there is a winning option out of four, there are three losing options. So, the chance of picking a wrong option is \frac{3}{4}
  • You are already given the probability of C, so we just record it: 0.6 = \frac{3}{5}
  • You can't roll a 7 on a standard die, so the probability is 0
  • Assuming a baby can be born on any day with the same probability, there is a \frac{2}{7} probability he's born on a weekend, since there are two weekend days out of 7 in a week
  • There are 4 aces out of 52 cards in a standard deck, so the probability of picking an ace is \frac{4}{52}=\frac{1}{13}
  • The sun will pretty surely rise tomorrow, so its probability is 1
  • This is quite ambiguous, since it's not a sentence that can be rigorously defined. The probability is surely high, since summer days are tipically hot, but how can we give an exact probability? What's the treshold for being hot?
  • A standard die has three even numbers (2,4,6) and three odd numbers (1,3,5). So, there is a probability of \frac{3}{6}=\frac{1}{2} to roll an odd number
  • Flipping two coins you can have the following outcomes: HH, HT, TH, TT. So, 3 times out of 4 you have at least one head, so the probability is \frac{3}{4}

So, if you order this probabilities, you have your scale

How do I solve this using the system of equations?
Westkost [7]

Answer:

length: 16 m; width: 13 m

Step-by-step explanation:

Write each of the statements as an equation. You know that the formula for the perimeter is ...

P = 2(L +W)

so one of your equations is this one with the value of P filled in:

• 2L + 2W = 58

The other equation expresses the relation between L and W:

• L = W +3 . . . . . . . . the length is 3 meters greater than the width

There are many ways to solve such a system of equations. Since you have an expression for L, it is convenient to substitute that into the first equation to get ...

2(W+3) +2W = 58

4W +6 = 58 . . . . . . . simplify

4W = 52 . . . . . . . . . . subtract 6

W = 13 . . . . . . . . . . . .divide by 4

We can use the expression for L to find its value:

L = 13 +3 = 16

The length is 16 meters; the width is 13 meters.

How many zeros will the 7 x 50 product have? explain how you know
Nadusha1986 [10]

Answer:

7x50 will have one 0 !

Explanation:

I usually just take the zero out and multiply the other numbers (7x5). So, seven times five is 35, then now i add the zero!

Step by step explanation:

7x5∅

7x5=35

Since I took away the zero, I will now add it back after I get the answer.

35←0

350

ONE ZERO!
