X = money in the accounts in March
x + 210 = x + 0.15x
210 = 0.15x
210/0.15 = x
1400 = x
check..
Isaah -- 1400 + 210 = 1610
Freddie -- 1400 + 0.15(1400) = 1400 + 210 = 1610
<span>March accounts = $ 1400 </span>
Try this solution (this is not the only way!):
Q1: if cosx=-0.5 and x∈(90;180), it means x=120°.
So, sin(x-30)=sin(120-30)=sin90°=1.
<u>answer</u>: 1.
Q2: it tgx= -1/√3 and x∈(270°;360°), it means x=330°.
So, sin(x+30)=sin(330+30)=sin360°=0.
<u>answer</u>: 0.
Answer:
ok, Im no exactly sure this is right becasue fractions aren't suppused to ever be a thing but here we go
Step-by-step explanation:
you want to get it to a same denominator.... so
2/3 times 5=10/15
3/5 times 5= 9/15
its asking about ATUL so, 10/15 divide 2=
ANSWER=5/15
hope this helped:)
Answer: 1068
Step-by-step explanation:
Formula of sample size :
, where p = prior population proportion , E = margin of error , = Critical z- value.
Let p = proportion of visitors who are repeat visitors.
Given : p=0.5
E= 3%= 0.03
critical z-value for 95% confidence = 1.96
Now,
[round to the next integer]
Hence, the required sample size = 1068
