The amount a money in the bank account can be expressed by the exponential equation A=300(1.005)^12t where A is the amount in do
1 answer:
Answer:
It will take more than 18.35 years for the amount in the account to be more than $900
Step-by-step explanation:
The amount in the bank account can be expressed by the exponential equation :
Where A is the amount in dollars
t is the time
We are supposed to find About how many years will it take for the amount in the account to be more than $900
So,
t>18.35
Hence It will take more than 18.35 years for the amount in the account to be more than $900

Question
<em>In a study of 100 new cars, 29 are white. Find p and q , where p is the proportion of new cars that are white. </em>
Answer:
p = 0.29 and q = 0.71
Step-by-step explanation:
Given
Total new cars = 100
White new cars = 29
Required
Determine p and q
From the question;
<em>p represents white new cars</em>
Hence;
Note that;
Substitute 29 for p
The proportion of p is calculate by dividing p by the total number of new cars (Same process is done for q)
For proportion of p
For proportion of q
Answer:
a) .033 b) .4678 c) 100
Step-by-step explanation:
Distribution of miraculin produced is normal. To answer question we need to find the z-score of 100g, 110g and 120g miraculin
General formula for z score is given by
z= where
- X is the miraculin produced (120,110,100)
- M is the mean miraculin produced for a partucilar tomato plant, which is 105.3
- s is the standard deviation of the sample, which is 8.0
a)
z-score for 120 g miraculin is =1.8375 then
P(x > 120) = P(z>1.8375) = 0.033
b)
z-score for 110 g miraculin is = 0.5875
z-score for 100 g miraculin is = -0,6625
P(100 < x < 110) = P(x>100) - P(x>110) =0.7462 - 0,2784 = 0.4678
c)
if P(x < a) = 0.25 then corresponding z score for a is -0.6745. From the above formula we can calculate a:
=-0.6625 which gives a= 100
