a meteorologist says that the probability of snow today is 45% what is the probability that will not snow​

Mathematics
1 answer:
WINSTONCH [101]2 years ago
5 0

Answer:

55%

Step-by-step explanation:

probability of something happening = p

probability of that thing not happening = 1 - P

45%= 45/100= 0.45

therefore, the probability of snow today = 0.45

therefore,

probability there will be no snow=1 - 0.45 = 0.55

probability there will be no snow= 0.55

convert 0.55 back to percentage= 0.55×100= 55%

probability there will be no snow= 55%

Solve the system using elimination: Help me please<br><br><br>12x - 8y = -12 <br><br>6x + 4y = -30
LUCKY_DIMON [66]

12x - 8y = -12  

6x + 4y = -30

Multiply the 2nd equation by 2, to make the Y coefficients opposite:

6x + 4y = -30 x 2 = 12x + 8y = -60

Now add the two equations:

12x -8y = -12 + 12x +8y = -60

=  24x = -72

Divide bothe sides by 24 to solve for x:

x = -72/24

x = -3

Now replace x with -3 in the first equation to solve for y:

12(-3) - 8y = -12

-36 - 8y = -12

Add 36 to each side:

-8y = 24

Divide both sides by -8 to solve for y:

y = 24 / -8

y = -3

X = -3 and y = -3

(-3,-3)

Answer:

Its the last option

y = 1488.33x + 23800 ; $172,600.

Step-by-step explanation:

The slope of the trend line = (median value for 2000 - median value for 1940) / 60

= 89300 / 60

= 1488.33.

So the equation is 1488.33x + 23,800

Estimate for 2040

is 1483.33* 100 + 23800

= 172,600.
