Answer: b+2=8
Step-by-step explanation:
Answer:
hello your question is incomplete attached below is the complete question
answer :
a ≈ - 136
b = 2.46
Step-by-step explanation:
A) we apply the formula for slope in regression
b = r *
--------- ( 1 )
where:
standard deviation (Sy) = 27.8913
standard deviation ( Sx ) = 11.2921
Linear correlation coefficient ( r ) = 0.9972
substitute given values into equation 1
b = 2.46
for intercept A
a = Y - b * X --------- ( 2 )
Mean number of ice bags sold ( Y )= 70.2873
b = 2.46
Mean temperature ( X )= 83.8959
substitute given values into equation 2
a = 70.2873 - ( 2.46 * 83.8959 )
= - 135.997
P (Jack) = 4 / 52 = 1/13
P(Queen) = 4/52 =1/13
P(jack or queen) = 1/13 + 1/13 = 2/13
