Answer:
The discount is 35%.
Step-by-step explanation:
94 - 61.10 = the amount that she got discounted for.
Which equals $32.90. She got discounted $32.90 dollars. To find out the percent of cash she got discounted for you would do:
$32.90 divided by $94.00
Which equals .35
Move the decimal over 2 places to the right, and you then have your answer, which is 35%.
She got discounted 35%.
Answer with Step-by-step explanation:
We are given that displacement of wave

Where y in cm and t in sec.
a.Compare it with

Amplitude of wave=A
We get A=1.5
Amplitude=A=1.5 cm
b.k=0.68


Using 
Wavelength of the wave=9.2 cm
c.Period=


The period of the wave=0.17 s
Speed of the wave=
Speed of the wave=54.1 cm/s
<h2>
Answer with explanation:</h2>
Given : Sample size 
Sample mean : 
Sample standard deviation : 
Let
be the population mean of "like" ratings of male dates made by the female dates.
As per question ,
Null hypothesis : 
Alternative hypothesis :
, It means the test is a one-tailed t-test. ( we use t-test when population standard deviation is unknown.)
Test statistic:

For 0.05 significance and df =188 (df=n-1) p-value = .001582. [By t-table]
Since .001582< 0.05
Decision: p-value < significance level , that means there is statistical significance, so we reject the null hypothesis.
Conclusion : We support the claim at 5% significance that t the population mean of such ratings is less than 8.00.
Answer:
Solve the following system for x and y:
{2 x + 53 = 53, 8 x + 3 = 42}
Check whether x and y are present in the given system:
Answer: The variable y is not present. Therefore its value cannot be determined.
