Answer:
I think the answer is -104,400,000,000,000,000
Step-by-step explanation:
Answer:
1. 42.8 °C
2. Aceves' class: $133.33; Baca's class: $266.67; Canyon's class: $200.
Step-by-step explanation:
1.) The difference between two numbers is found by subtraction. Since we want to report the positive difference, we can subtract the smaller number from the larger:
-21.2 °C - (-64 °C) = (64 -21.2) °C = 42.8 °C
The temperature must drop 42.8 °C more for the antifreeze to solidify.
_____
2.) We want to divide the prize money in the ratio
1200 : 2400 : 1800 = 2 : 4 : 3
There are 2+4+3 = 9 total ratio units, so each one must stand for $600/9 = $66 2/3.
Then the money to Aceves' class is ...
2 × $66 2/3 = $133 1/3 = $133.33
And the money to Baca's class is ...
4 × $66 2/3 = $266 2/3 = $266.67
Finally, the money to Canyon's class is ...
3 × $66 2/3 = $200.00
___
Note on the division:
The 1/3 cent that Aceves' class should have gotten goes to Baca's class in the above scenario. It might make sense for the classes to donate $6 to the school and divide the remaining $594 as $132 : $264 : $198. If they actually want the pennies, they could donate $0.06 to the school and split the result as $133.32 : $266.64 : $199.98.
Answer:
The probability that the woman selected does not have red/green color blindness is 0.9945.
Step-by-step explanation:
Let <em>X</em> = a woman has red/green color blindness.
It is provided that, in a certain group of women the rate of red/green color blindness is <em>P</em> (<em>X</em>) = 0.0055.
A complement of an event <em>E</em>, is defined as the event of not <em>E</em>.
The probability of complement of an event <em>E</em> is:
Compute the probability that the woman selected does not have red/green color blindness as follows:
Thus, the probability of the complement of the event of a woman having red/green color blindness is 0.9945.
