We need to find, how many 1/3s are in 1 2/3 the hexagon represents 1 whole.
In order to find that value, we need to divide 1 2/3 by 1/3.
Let us first convert 1 2/3 into improper fraction first.
1 2/3 = (1*3+2)/3 = 5/3.
Therefore,
5/3 ÷ 1/3.
Changing division sign into multiplication and flipping the second fraction, we get
5/3 × 3/1
3's cross out from top and bottom, we get
= 5.
<h3>Therefore, there are 5 times of 1/3s in 1 2/3.</h3>
Answer:
20
Step-by-step explanation:
24.80-6.80=$18 that's what Britta spent on equal number of carrots and apples because $6.80 was spent on extra carrots only.
18/ .90=20 that means she got 20 apples and 20 carrots before she added $6.80 to buy some extra carrots
Thus, the number of apples Britta bought = 20
340 is the answer divid them by 2 and there ur answer hope it helped
Answer:
The percentage of people going to the people in week 4 compared to week 1 decreased by 25%.
Step-by-step explanation:
Week 1: 1,040 people
Week 2: 105 fewer people
1040 - 105 = 935 people
Week 3: 135 more people
935 + 135 = 1070 people
Week 4: 290 fewer people
1070 - 290 = 780 people
So, there were 260 fewer people, going to the pool in those 4 weeks compared to week 1.
Now, we must find the percentage change.
x/100 = 780/1040
Cross multiply.
1040x = 78000
Divide both sides by 1040 to leave x by itself on one side.
x = 78000/1040
x = 75%
This means only 75% of the total people from week one were going to the pool in week four. Therefore, there was a 25% decrease in the number of people who went to the pool over these four weeks.
Answer:
a)
<em> you are unwilling to predict the proportion value at your school = 0.90</em>
<em>b) </em>
<em>The large sample size 'n' = 864</em>
<em></em>
Step-by-step explanation:
Given estimated proportion 'p' = 10% = 0.10
<em>Given Margin of error M.E = 0.02</em>
<em>Level of significance α = 0.05</em>
a)
<em> you are unwilling to predict the proportion value at your school </em>
<em> q = 1- p = 1- 0.10 =0.90</em>
b)
<em>The Margin of error is determined by</em>
Cross multiplication , we get
√n = 29.4
<em>Squaring on both sides , we get</em>
<em> n = 864.36</em>
<u><em>Conclusion</em></u><em>:-</em>
<em>The large sample size 'n' = 864</em>
<em></em>
