Answer: 1.300228
Step-by-step explanation:
The t-score we use for the confidence interval is two-tailed , i.e. the t-score should be used to find a () is given by :-
, where n is the sample size.
Given : Level of confidence:
Significance level :
Sample size : n= 47
Then, degree of freedom :
Now by using standard normal t-distribution table,
Hence, the t-score should be used to find a 80% confidence interval estimate for the population mean = 1.300228
Answer:
$77429.824
Step-by-step explanation:
Let the total college cost for one year = x
43% of x was paid with scholarship fee
Percentage left = 100% - 43% = 57%
57% is equivalent to 11,033.75
57/100x= 11,033.75
0.57x = 11033.75
x = 11033.75 / 0.57
x =19357.456 ; this is Jacinta's college fee for a year ;
Hence
College fee for 4 years :
19357.456 * 4 = $77429.824
Answer:
In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
So as we see here, they all look the same. But I can see that it says only ONE of the PAIRS of triangles is congruent.
What I can tell is that
Number 1 and 3 are probably congruent since they both have the same shape, and size.
