Answer:
The estimate is
Step-by-step explanation:
From the question we are told that
The sample size is n = 522
The sample proportion of students would like to talk about school is
Given that the confidence level is 90 % then the level of significance can be mathematically evaluated as
Next we obtain the critical value of from the normal distribution table, the value is
Generally the margin of error can be mathematically represented as
=>
=>
Generally the estimate the proportion of all teenagers who want more family discussions about school at 90% confidence level is
substituting values
Based on the quadrilateral given, the values of the missing measures will be:
- VU = 15
- SU = 21.21
- TV = 21.21
- SW = 10.61
A quadrilateral simply means a polygon that has four sides, edges and vertices.
Based on the information given, SU = TV and this will be:
= ✓450 = 21.21
SW = 21.21/2 = 10.61
Also, for the second shape, the values will be:
OM = 46; PN = 23, ON = 46; MN = 46.
