Answer:
y = 2/5x + 4
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Slope:
( y1 - y2 ) / ( x1 - x2 )
( 2 - 8 ) / ( -5 - 10 )
( -6 ) / ( -15 )
2 / 5
Y-Intercept:
8 = 2/5(10) + b
8 = 4 + b
4 = b

Answer:
209.005 gms
Step-by-step explanation:
Given that the weights of packets of cookies produced by a certain manufacturer have a Normal distribution with a mean of 202 grams and a standard deviation of 3 grams.
Let X be the weight of packets of cookies produced by manufacturer
X is N(202, 3) gms.
To find the weight that should be stamped on the packet so that only 1% of the packets are underweight
i.e. P(X<c) <0.01
From std normal table we find that z value = 2.335
Corresponding x value = 202+3(2.335)
=209.005 gms.
He would need a 93% on his fourth exam.
94+89+96+93= 372, 372 divided by 4= 93
