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:
40 teabags for 0.96 (this is the most british question I've ever saw)
Step-by-step explanation:
1.62 / 60 = 0.027 (price per teabag)

Answer:
8820.26 yd
Explanation:
the formula for finding the area of a circle is π × radius². since the diameter of the circle is given, we can simply divide it by 2 to find the radius.
106 ÷ 2 = 53
now, we can substitute this into the formula:
π × radius²
= 3.14 × 53²
= <u>8820.26 yd</u>
i hope this helps! :D
I think you meant 5,244 ÷ 6 = 874.
Answer/Step-by-step explanation:
We can check if this 5,244 ÷ 6 = 874 is correct by doing it opposite.
Since it 5,244 divide 6 we can do 874 x 6.
