Answer:
$500
Step-by-step explanation:
let x = price of the dress before reductions
If the price is reduced by 60%, the price would be (100% - 60%) = 40%
Price after first reduction= 0.4x
Price after second reduction = 0.4(0.4x)
0.16x = $80
Divide both sides by 0.16
x = $500

Have a good day :)
In general, in polar coordinates (r, ω) = (-r, ω+π), because when you add π radians to an angle you are turning 180 degrees and then need to change the sign of the radius to preserve the original point.
Then (-5, π/4) = (5 , π/4 + π) = (5, 5π/4)
Answer: (5, 5π/4)
Answer:
6x²
Step-by-step explanation:
The GCF of 24 and 36 is 6
The GCF of x³ and x² is x²
Thus the GCF of 24x³ + 36x² is 6x²
Answer:
Claim : men weigh of wild jackalopes is 69.9
The null hypothesis : H0 : μ = 69.9
Alternative hypothesis : H1 : μ ≠ 69.9
Test statistic = −2.447085
P value = 0.0174
Conclusion :
Fail to Reject the Null hypothesis
Step-by-step explanation:
From the question given :
The claim is that : mean weight of wild jackalopes is still the same as 10 years with a mean weight of 69.9 lbs.
The null hypothesis : H0 : μ = 69.9
Alternative hypothesis : H1 : μ ≠ 69.9
Using calculator :
Sample mean (x) = 66
Sample standard deviation (s) = 12.345
The test statistic t :
(x - μ) / (s/√n)
n = sample size = 60
(66 - 69.9) / (12.345 / √60)
t = −2.447085
P value at α 0.01, df = 59 is 0.0174
Since the p value is > 0.01, the result is not significant at 0.01. Therefore, we fail to reject the Null
