Answer: 45,000.
Step-by-step explanation:
The equation of inverse variation is given by:-
, where k is the constant of proportionality.
Given: After owning the car for 3 years, its value is $15,000. After owning the car for 5 years, its value is $9,000.
Here,
Then,
or [answer is same in both cases.]
Hence, the constant of proportionality in this inverse variation is 45,000.
Answer:
Opposite angles of a cyclic quadrilateral add to 180°
Angel CBA and angle ADC adds up to 180°.
CBA + ADC = 180
CBA = 180 - ADC
x + CBA = 180
x + 180 - ADC = 180
x - ADC = 0
x = ADC
y + ADC = 180
y + x = 180

Answer with explanation:</h2>
Claim : The population variance of these resistors "must not exceed 4" to conform to industry standards.
Then , the set of the hypothesis will be :-
The critical value of chi-square is 16.919 and the observed value is 15.247 .
We know that if the chi-square observed value is less than the chi-square critical value, then we fail to reject the null hypothesis.
Since 15.247<16.919
So , we conclude that we do not reject the null hypothesis.
Hence, we have enough evidence to support the claim that the population variance of these resistors "must not exceed 4" to conform to industry standards.
