Answer:
No, we can't make 20 by adding 5 odd numbers.
Step-by-step explanation:
An odd number is represented by 2n+1, the sum which we got is represented in this form, so it's obviously an odd number. But 20 is an even number, so sum can't be 20.
Answer: 3.20kg
Step-by-step explanation:
Hiro has 5 kilograms of potatoes and 2 kilograms of onions. The total kilogram of the produce will be:
= 5kg + 2kg
= 7kg
Since he plans to use 3.25 kilograms of potatoes and 550 grams of onions for a recipe. The total kilogram that he plans to use will be:
= 3.25kg + 0.55kg
= 3.80kg
Therefore, the total kilograms of the produce will not be used will be:
= 7kg - 3.80kg
= 3.20kg
Note:
1000grams = 1 kilogram
550gram = 550/1000 = 0.55kg

Step-by-step explanation:
Answer: 151
Step-by-step explanation:
if prior population proportion is unknown , then the formula is used to find the sample size :
, where 
= Two tailed critical value for significance level of 
E = Margin of error.
Given : margin of error = 8%= .08
For 95% confidence level , two tailed critical value = 1.96
Now, the required sample size :
Hence, the size of the sample needed = 151.
