To rename the number 9,200 in hundreds, we understand that '1' in thousands is equivalent to ten hundred. Hence, 9,200 divided by 100 equals 92 but 9,200 in hundreds is represented as 9200 hundreds.
Renaming the number 9,200 in hundreds means we are converting the value into groups of hundreds. Since each '1' in thousands is equal to ten hundred, we multiply the value of the thousands by ten. Therefore, 9,200 divided by one hundred is 92 and if you want to represent this number in hundreds, it would be equal to 9200 hundred.

Given data:
Sample size
Sample proportion of people support candidate A:
Population proportion of people support Candidate A :
Check the condition: and
Null Hyposthesis:
Alternative Hypothesis:
The test statistics:
Plug in p=0.56, P=0.40 and n=100 in the above formula,
The table value of z at 10% of significance level is 1.28
Table value is less than the calculated value.
Hence is rejected at 10% level.
Therefore there is the evidence at an alpha level of 10% to conclude that the percentage of people who support candidate A has changed.
Answer:
40 cm²
Step-by-step explanation:
A = 2(lw + lh + wh)
= 2(4×2 + 4×2 + 2×2)
= 2(8 + 8 + 4)
= 2×20
= 40 cm²
Answer:
40cm^6
Step-by-step explanation:
surface area of this box
=2(lw+lh+wb)
=2(2×4+4×2+2×2)cm^6
=2(8+8+4)cm^6
=2×20cm^6
=40cm^6
