The battery would be $. 50 meaning the torch is $2.00. 2 dollars is 80% of $2.50 meaning the torch is 80% of the total price.
Answer: 1/6 of a pound.
Step-by-step explanation: Divide 2/3 pounds by 4 people. To do this, multiply 2/3 by 4's reciprocal, which is 1/4. The reciprocal of a number is basically the reverse form of that number. 4 as a fraction is 4/1. The reciprocal of that would be 1/4. Hopefully you understand.
2/3 times 1/4 is 2/12. Simplify by dividing 2/12 by 2 and 12's greatest common factor: 2. 2 divided by 2 is 1; 12 divided by 2 is 6. Your final answer is 1/6.
To start, let’s put order the amounts of candy in numerical order
2, 4, 5, 7, 8, 11, 11
Now let’s look at the ranges given
0-3, 3-6, 6-9, 9-12
Now let’s sort how many bags are in each range
There’s one bag between 0-3, so raise the first bar to one
There’s 2 bags between 3-6, so raise the second bar to two.
There’s two more bags between 6-9, so raise the third bar to two
Finally, there’s two bags between 9-12, so raise the last bar to two.
Answer:
30 and -3
Step-by-step explanation:
30 x -3=-90
30-3=27
Answer:
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to conclude that the population proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing
Step-by-step explanation:
From the question we are told that
The sample size is n = 16
The population proportion = 0.5
The number that of students that picked out the teachers dog is k = 14
Generally the sample proportion is mathematically represented as

=> 
=> 
The null hypothesis is 
The null hypothesis is 
Generally the test statistics is mathematically represented as



Generally the p-value is mathematically represented as

From the z table the probability of Z>3 is mathematically represented as

So

Let assume the level of significance is 
Generally from the value obtained we see that
Hence
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to conclude that the population proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing
