Answer:
1,350/x
Step-by-step explanation:
The prize would be $1,350 divided by the amount of people on the team. Since we don't know the number of people on the team, that number is represented by the variable 'x.'
11 dollars is I think what Ken or the kids name spent IDK
Table: The number 60 goes underneath 5.
The number 7 goes above 84.
120 under 10.
12 above 144.
Explanation: Refer to the next question. Each ratio will equal out to 1/12 so you either divide or multiply 12 for each one.
5x12=60
84/12=7
10x12=120
144/12=12
1. 1/12
Explanation:
2 packets of flavoring to 24 ounces of water, 24/2 is 12.
4. 276 ounces of water
Explanation:
12 ounces of water to every packet of flavoring so we need to multiply 23 by 12 which equals 276.
5. Yes. (9.5, 114) makes sense because it follows the ratio of 1:12. 114/9.5=12; 9.5x12=114.
6. 36/3, 66/5, 108/9, 180/15
Explanation:
24/2 = 12, multiply each bottom number by 12 and divide each top number by 12.
7. It uses multiplication because you are multiplying by 12.
Answer:
x = 3
Step-by-step explanation:
6x - 4 = 2x + 8
6x - 2x = 8 + 4
4x = 12
x = 12/4
x = 3
Answer:
Null hypothesis:
Alternative hypothesis:
Step-by-step explanation:
Assuming this previous info: Bags of a certain brand of tortilla chips claim to have a net weight of 14 ounces. Net weights actually vary slightly from bag to bag and are normally distributed with mean . A representative of a consumer advocate group wishes to see if there is any evidence that the mean net weight is different with advertised and so intends to test the hypotheses
Data given and notation
represent the mean height for the sample
represent the sample standard deviation for the sample
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to check if the true mean is equal to 14 or no, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
If we analyze the size for the sample is < 30 and we don't know the population deviation so is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:
(1)
t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".
Calculate the statistic
We can replace in formula (1) the info given like this:
