Answer:
the pennies does not conform to the US mints specification
Step-by-step explanation:
z = (variate -mean)/ standard deviation
z= 2.5 - 2.4991 / 0.01648 = 0.0546
we are going to check the value of z in the normal distribution table, which is the table bounded by z.
checking for z= 0.0 under 55 gives 0.0219 (value gotten from the table of normal distribution)
we subtract the value of z from 0.5 (1- (0.5+0.0219)) = 0.4781 > 0.05claim
since 0.4781 > 0.05claim, therefore, the pennies does not conform to the US mints specification
the claim state a 5% significance level whereas the calculated significance level is 47.81%. therefore, the claim should be rejected
26+0.08x=8+0.13x
26-8=0.13x-0.08x
18=0.05x
x=18/0.05=360 min
Answer:
jesus...you're twisted anyway 69 :)
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. First you add like terms
12b+5.54b+2.46b-2b = 18b
3.2a+1.17a = 4.37a
2. Now you write it out
18b+4.37a
3. CELEBRATE!!!!
4. Pat yourself on the back one more problem done
