Answer:
(e) The researcher should use a t-distribution because they do not know the true standard deviation of daily sugar intake in Durham county.
Step-by-step explanation:
A t-distribution is used when the true standard deviation (population standard deviation) is unknown. t-distribution uses the standard deviation of the samples.
In this case, it is the sample standard deviation that is known, therefore, the researcher should use a t-distribution.
Answer:
I belive it would be c
Step-by-step explanation:
because if you read the question it says the lowest point altho they are equale it still makes sence to put c
The polygons are said to be similar if and only if the ratio of the measures of their corresponding sides are equal. If we are to establish the equation by the definition given above that would be,
15/10 = 60/x
The value of x from the equation is 40. Hence, the side measures 40.
ANSWER: 40
The answer is the last choice.
Given, y varies directly as x
So,
Where c is a constant
When y equals 5 when x is 8
So,
So, the relation between y and x
now , when x = 9
Substitute with x to find y
So, the answer is option 2. y = 45/8
If i could see the paper i prob. could help cause i am really good in scienc and biology
