(-6/5, -8/5), you substitute 3x+2 for the y in the first equation. So the first equation will read 2x+3x+2, then you solve and get x= -6/5. Then you have to solve for y, so you put your x value (-6/5) in the second equation for x. it should read y= 3(-6/5)+2, the answer to that is y= -8/5. After that you just put them in order (x,y) and there's your answer.
Answer:
Mean = 10.2
Standard deviation = 4.0
Step-by-step explanation:
The average age = mean age
Mean = (16 + 10 + 5 + 7 + 13)/5
Mean = 51/5 = 10.2
What is the standard deviation will be square root of variance
(16 - 10.2) + (10 -10.2) + (5-10.2) + (7-10.2)+( 13-10.2)
5.8 + 0.2 -5.2 - 3.2 + 2.8
Square each number
33.64 + 0.04 + 27.04 + 10.24 + 7.84
Variance = 78.8/5 = 15.76
Standard deviation = 3.969 = 4.0
Answer:
Square root of 15
√ 15 = 3.9 (Rounding to the nearest tenth)
Square root of 97
√97 = 9.9 (Rounding to the nearest tenth)
Square root of 40
√40 = 6.3 (Rounding to the nearest tenth)
Step-by-step explanation:
Square root of 15
√ 15 = 3.9 (Rounding to the nearest tenth)
Square root of 97
√97 = 9.9 (Rounding to the nearest tenth)
Square root of 40
√40 = 6.3 (Rounding to the nearest tenth)
Location on a number line
√ 15, between + 3 and + 4, very close to +4
√40, between + 6 and + 7, close to +6
√97, between + 9 and + 10, very close to +10
Answer:
(-7)^8
Step-by-step explanation:
