Answer:
Step-by-step explanation:
Given that the Acme Company manufactures widgets, which have a mean of 60 ounces and a standard deviation of 7 ounces
We know that 95% of the area lie between -2 and 2 std deviations from the mean.
i.e. Probability for lying in the middle of 95%
Z score 
Between 46 and 74 oz.
b) Between 12 and 57
convert into Z score
P(-6.86<z<-0.43)
=0.5-0.1664=0.3336
c) X<30 gives Z<-4.83
i.e. P(X<30) =0.00
Answer: Angles 2 and 3 are vertical angles
Step-by-step explanation:
Vertical angles are angles that are not adjacent, and are made by the same 2 lines.
Answer:
y=2x -1
Step-by-step explanation:
Finding x-intercepts and y-intercepts
1-To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
2-To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
3-To find the y-intercept, set x = 0 \displaystyle x=0 x=0.
