Answer:
1/2.
Step-by-step explanation:
Let O = an odd number and E an even number.
The possible outcomes for an odd sum are:
OOO
OEE
EOE
EEO
The probability of an odd on each pick = 50/100 = 1/2 and for an even it is also 1/2.
Prob( O O O) = 1/2*1/2*1/2 = 1/8.
The probability for the other 3 possible outcomes is also 1/8 , therefore the probability for odd number totals = 4 * 1/8
= 1/2.
Answer: False
Step-by-step explanation:
Two negatives equals a positive
10. Kim gets $7 per hour and gets charged $1 for gloves
Use y to represent her pay and x to represent hours worked.
The equation is y = 7x - 1 because she gets 7 times x hours and there is a minus 1 because of the charge of gloves.
11. The table shows that each increasing hour, 8$ is added. Therefore we need to find the bonus that Kit receives just for showing up. This is when hours equals 0. If 3 hours is 27$ pay, then 2 hours is 19$ pay, 1 hour is 11$ pay and 0 hours is 3$ pay. We find that there is a 3$ bonus just for showing up.
Therefore the equation is y = 8x + 3
12. At x = 0, y = 2 so the y-intercept is 2. The slope is going down 4 and right one which means the slope is -4. The y-intercept is b and the slope is m. If we plug these values into the equation y = mx + b we get:
y = -4x + 2
13. At x = 0, y = -3 so the y-intercept is -3. The slope is going up 1 and right 4 which means the slope is 1/4. The y-intercept is b and the slope is m. If we plug these values into the equation y = mx + b we get:
y = 1/4 x - 3
100-99=1
98-97=1
...
4-3=1
2-1=1
Any number subtracted from a number greater than it by one will always have the result of 1.
