Answer: rate of interest (r) = 6.25
Step-by-step explanation:
Simple interest formula is S.I = PxTxR/100
From the question ;
S.I = (3/8) principal
3/8p = px6xr/100
Eliminate p on both sides of the equation
r = (3x100) / (8 x 6)
r = 300 / 48
r = 6.25
Step-by-step explanation:
A,
because we can use the formula y=mx+c
Answer:
393 bacteria
Step-by-step explanation:
First find how much it would increase per hours :
1900 / 29 = 65.5172414
Then take this and multiply it by 6 to get :
393.103448
Round it to the nearest whole number to get:
393 bacteria
Answer:
<em>The sample size 'n' = 721</em>
<em>Number of cars 'n' = 721</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<em>Given Population proportion 'p' = 0.40</em>
<em>Given Margin of error = 0.03</em>
<em>90% of level of significance </em>
<em> </em><em></em>
<em>The Margin of error is determined by</em>
<em></em><em></em>
on calculation , we get
0.03√n = 0.8058
squaring on both sides , we get
n = 721.45≅721
<u><em>conclusion</em></u>:-
<em>The sample size 'n' = 721</em>
<em>Number of cars 'n' = 721</em>
