Answer:
1 apple costs $1.2
1 pear costs $1
Step-by-step explanation:
Represent Apples with A and Pears with P
For the person in my front, the expression is:
For me, the expression is
Hence, the system of equation is:
Solving for the values of A and P.
Substract equation (2) from (1)
<em>Hence, 1 pear costs $1</em>
Substitute 1 for P in
<em>Hence, 1 apple costs $1.2</em>
Answer with explanation:
Let p be the population proportion.
Given : The chain will open if there is evidence that more than 5,000 of the 20,000 households in the area are equipped with Blu-ray players.
i.e.
Since alternative hypothesis is right-tailed , so the test is right-tailed test.
Also, Sample size : n= 300 ,
Sample proportion:
Test statistic:
i.e. Observed test statistic Value = 2.80
(A) is right option.
Critical value for 5% significance level for right tailed test :-
Since , the observed z-value is greater than the critical value , so we reject the null hypothesis.
Conclusion : We have sufficient evidence to supposrt the alternative hypothesis.
So, The chain will open if there is evidence that more than 5,000 of the 20,000 households in the area are equipped with Blu-ray players.
2 Rabbits multiplied by 4 equals 8 multiplied by 12 equals 96.
Just Half it down the middle.
