First off subtract the cost of the computer from the total cost
1,220-995 = 225
Then divide 225 by 3 to get the price of each of the software
225/3 = $75
-8 + 11 = 3
3 + -5 = -2
Your answer is -2
Answer:
0.29
Step-by-step explanation:
z-score is given by the formula:
z=(μ-M)/σ where
- μ is the hypothesis drive distance, which is 222
- M is the mean sample drive distance
- σ is the standard deviation of the sample drive distance
Therefore
z=(222-218)/14≈0.29
<span>Answer: Option D. 1/12
We have:
3 Necklaces (red, green, and gold)
2 Bracelets (red and black)
6 hats (silver, yellow, green, gold, black, and white)
The number total of combinations is:
C=3x2x6→C=36 possible combinations
What is the probability of Suzy choosing a red bracelet and silver hat?
Possible combinations with a red bracelet and silver hat:
C1=1 (red bracelet) x 1 (silver hat) x 3 (necklaces: red, green, and gold)
C1=3 possible combinations with a red bracelet and silver hat
Probability of Suzy choosing a red bracelet and silver hat: P=C1/C
P=3/36
Simplifying the fraction dividing the numerator and the denominator by 3:
P=(3/3) / (36/3)
P=1/12
Answer: The probability of Suzy choosing a red bracelet and silver hat is 1/12</span>
Answer:
1608 cm^2
Step-by-step explanation:
Bottom: (6+15)*30=630
Front: 8*15/2+8*6/2=60+24=84
Back: Same as front
Right side: 30*17=510
Left side: 30*10=300
Add everything together: 1608
Hope this helps!
