Answer:
The minimum number of letters John has to send to be sure that Peter receives his letter is 127 letters
Step-by-step explanation:
The four digit numbers that are multiples of 5 and 7 with the last digit = 0 is found as follows
Since the last digit of the house number = 10, then the house number is divisible by 10 which also meets the condition that the house number is divisible by 5
We have the four digit numbers from 1000 to 9999
Hence the numbers divisible by both 7 and 10 are from (1000/70 (Which is 14 + 2/7) - 2/7)×70 + 70 = 1050 to (9999/70 (Which is 142 + 59/70)- 59/70)×70= 9940
Which gives 142 - 15 = 127 numbers which are four digit number multiples of 5 and 7 with the last digit = 0
Hence the minimum number of letters John has to send to be sure that Peter receives his letter = 127 letters.
Add the three items he wants to buy:
4.95 + 9.10 + 5.50 = 19.55
Subtract how much he has already:
19.55 - 2.30 = 17.25
He needs $17.25 more

Answer:
There is enough evidence to support the attorney’s claim
Step-by-step explanation:
Given that one attorney claims that more than 25% of all the lawyers in Boston advertise for their business.
Sample size n =200
Sample proportion = 
Hypotheses:
(right tailed testat 5% significance level)
Assuming H0 to be true, std error of p = 
Test statistic z = p diff/std error
= 
p value for one tailed =0.0170
Since p <0.05 we reject null hypothesis
There is enough evidence to support the attorney’s claim
