Answer:
Step-by-step explanation:
Given:
- Daria used fraction tiles to show that 3/5 is equivalent to 6/10
The two number are equal, because the simplest form of 6/10 = 3/5
The size of fraction tiles in 3/5 is double the one in 6/10
Please have a look at the attached photo, in fraction 3/5 we have 3 shaded units and in fraction 6/10 we have 6 shaded units.
Hope it will find you well.
Answer:
The margin of error is<em> 0.22</em>
Step-by-step explanation:
Mathematically, the margin of error at the given confidence interval can be calculated using the formula below;
Margin of error = × s/√n
where is the t-value at the given confidence interval, s is the standard deviation and n is the sample size
= 1.96 (From t-distribution table)
s = 2.5 inches
n = 500
MOE = 1.96 × 2.5/
MOE = 1.96 × 2.5/22.36
MOE = 0.22
15,17,19 are all odd numbers and add to 51
