16: 10(-9) +4 = -90 +4 = -86
17. 7^2 - 7 = 49-7 = 42
18. -9^2 - -9 = 81+9 = 90
19. 10(5) +4 = 54, 3*54 = 162
20. 3*5 = 15, 10(15) +4 = 154
Answer:
13.1%
Step-by-step explanation:
The company estimated that there would be 500 a ps during the football season
The actually sold 575
Therefore the percent error can be calculated as follows
= 575-500/575 × 100
= 75/575 × 100
= 0.1304×100
= 13.1%
Hence the percent error is 13.1%
Answer:
its true for all values so the answer is 0=0
Step-by-step explanation:
Answer:
a) You roll a die 25 times. Let X be the number of times that you roll "3".
* Is a Binomial
b) The SJSU football team will play 12 games next season. They have a 70% chance of winning each conference game and a 60% chance of winning each nonconference game. Let X be the number of games the SJSU football team wins next season.
* Not a Binomial because probability of success is not constant
c) Evelyn has a 75% chance of getting an A in each class she takes. Let X be the number of times Evelyn earns an A during four years at SJSU.
* Is a Binomial
Step-by-step explanation:
step 1. all the side length are different therefore all of the internal angles are different.
step 2. a triangle with all different angles is scalene.
step 3. all of the angles are less than 90°
step 4. a triangle with all angles less than 90° is acute.
