Answer: 5%
Step-by-step explanation:
Given that:
Ticket price of jacket = $199
Final price after addition of sales tax = $208.95
Percentage sales tax on the jacket =?
Final price after addition of sales tax = price of jacket + amount of sales tax paid
208.95 = 199 + amount of sales tax paid
amount of sales tax paid = 208.95 - 199
amount of sales tax paid = $9.95
Let Percentage of sales tax = x
(x / 100) * 199 = 9.95
199x / 100 = 9.95
199x = 995
x = 5
Hence percent sales tax paid = 5%
Answer:
Step-by-step explanation:
From the given information:
The sample size is 28
The population mean is 24.5 (ppb)
The sample mean is 225.3 (ppb)
Thus, the null and the alternative hypothesis can be computed as:
Null hypothesis:
Alternative hypothesis:
Let's find the equivalent expressions ~
#1. PROBLEM
#2. PROBLEM
The problem to number 1 is a inequality, so
x-2<-7
x<-5
since it is < it will have open dot.
Answer: C
2. x/3>-3
x>-9
Answer: D
3. 5p+26<72
5p<46
p<9.2
Answer: C
4. -3w+3>=18
-3w>=15
x<=-5
5. 15x-21>= 12x+18
x>=13
Answer A
6: |3x|=15
Absolute values positive so {-5,5}
Answer: B
7: |2x-3|=5
x=4,-1
Answer: C
Answer:
x=9
Step-by-step explanation:
The triangle is equilateral which means the sides are equal.
x+9 = 2x
Subtract x from each side
x+9-x = 2x-x
9 =x
