Answer: Jeremy drove 84 miles.
Step-by-step explanation:
Let x represent the number of miles that Brenda drove.
If Jeremy drove twice
as far as Brenda, it means that the distance covered by Jeremy would be 2x miles
When they stopped after some time, they were already
126 miles apart. This means that the total distance covered by both of them is 126 miles. Therefore,
x + 2x = 126
3x = 126
x = 126/3
x = 42 miles
The number of miles that Jeremy drove is
42 × 2 = 84 miles
Answer:
Interest= $423.59
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $6,000
Number of periods (n)= 3 years
Interest rate (i)= 2.3% = 0.023
<u>To calculate the Future Value, we need to use the following formula:</u>
FV= PV*(1+i)^n
FV= 6,000*(1.023^3)
FV= $6,423.59
<u>Now, the interest earned:</u>
<u />
Interest= 6,423.59 - 6,000
Interest= $423.59

Answer:
Probability that an ear of corn selected at random will contain no borers is 0.4966.
Step-by-step explanation:
We are given that the distribution of the number of borers per ear approximated the Poisson distribution. The farmer counted 3,500 borers in the 5,000 ears.
Let X = <u><em>Number of borers per ear</em></u>
The probability distribution of the Poisson distribution is given by;
where, 
= parameter of this distribution and in our question it is proportion of bores in the total ears = 
= 0.7
SO, X ~ Poisson( = 0.7)
Now, probability that an ear of corn selected at random will contain no borers is given by = P(X = 0)
P(X = 0) = 
= 
= <u>0.4966</u>
Hence, the required probability is 0.4966.
Answer:
8
Step-by-step explanation:

-5(a+3)=- 55
-5a-15=- 55
-5a= -55+15
-5a= -40
-5a/-5 =-40/-5
a=8
