Add: 5 + 3 = 8
Exponentiation: the result of step No. 1 ^ 2 = 8 ^ 2 = 64
Add: 32 + 2 = 34
Subtract: the result of step No. 2 - the result of step No. 3 = 64 - 34 = 30
Multiple: 5 * the result of step No. 4 = 5 * 30 = 150
Add: 8 + the result of step No. 5 = 8 + 150 = 158
plz mark me as brainliest :)
I think it’s X=-3+(the square root of 2)

, 3, 5 are the prime factors of 60.
Step-by-step explanation:
Answer:
Y = 0.4925X - 22.26 ;
(-12.413, 13.398) ;
Yes, there is
Step-by-step explanation:
X = IQ Score ; Y = musical aptitude
The regression equation from the table given using the slope and intercept coefficient :
Y = 0.4925X - 22.26
0.4925 = slope ; Intercept = - 22.26
The 95% confidence interval of the slope :
Confidence interval = b ± Tcritical*SE
Tcritical at 95%, df = n - 2 = (20 - 2) = 18
Tcritical = 2.1009
b = slope Coefficient = 0.4925
S.E = 6.143
Hence, we have :
Confidence interval = 0.4925 ± (2.1009 * 6.143)
Confidence interval = 0.4925 ± 12.9058287
Lower boundary = 0.4925 - 12.9058287 = - 12.413
Upper boundary = 0.4925 + 12.9058287 = 13.398
(-12.413, 13.398)
There is a significant relationship between IQ score and musical aptitude because, 0 is within the confidence interval obtained.
