The probability that at least one will be lit is 99.9%.

To find the probability that at least one is lit we start with the probability that they all burn out:

(0.1)(0.1)(0.1) = 0.001

The probability that one or more of them is lit is 1-(the probability none are lit):
1 - 0.001 = 0.999 = 99.9%

“Find 24% of $240.”<br><br> I keep trying and getting a different answer each time, please help
Nimfa-mama [501]

Answer:

$57.60

Step-by-step explanation:

The first thing you want to do is convert 24% to a decimal. To do this you just need to take the current decimal place and move it 2 places to the left. Since this percentage is a whole number the decimal is just after the 4.

(0.24)

Multiply that decimal by the number you want to find the percentage of

$240 * .24 = $57.60

What is the answer to this??
Firdavs [7]

Answer:

x=3

z=65

Step-by-step explanation:

6x+97 and 14x+73  are vertical angles which means they are equal

6x+97= 14x+73

Subtract 6x from each side

6x-6x+97= 14x-6x+73

97 = 8x +73

Subtract 73 from each side

97-73 = 8x+73-73

24 = 8x

Divide each side by 8

24/8 = 8x/8

3 = x

Now we need to find z

6x+97  and z are supplementary angles which means they add to 180

6x+97 +z = 180

6(3) +97 +z = 180

18+97+z=180

Combine like terms

115+z = 180

Subtract 115 from each side

115-115 +z=180-115

z = 65
