Answer:
$2475 or $1875
Step-by-step explanation:
Assuming the question meant to say $25 less than the original price, it would be $2475 because $2500-$25= $2475
However, if the question meant to say that Sam bought the iron for 25% less than the original price, it would be $1875 because 2500*0.25= $625
$2500-$625= $1875
Answer:
and? obviously bc 3 isnt a even number so then the answer wont be even
The answer is D.4/63. This is because you have to start by multiplying to get the denominators to be the same. in this case, we multiply by 9 and 7 to get 63. Then, what we did to the top must be done to the bottom, so we multiply to end up with 18/63 and 14/63.
Answer:
a) {}
b) The interval notation is
c) See graph in attachment
Step-by-step explanation:
a) We want to solve the inequality
We group like terms to obtain
Divide both sides by 7 ;
or
{}
b) The interval notation is
c) Since the -4 is not part of the solution we use a hollow circle.

Answer:
0.289792.
Step-by-step explanation:
If we define a month with one or more accident as "success"; and
A month with no accident as "failure" .
- P(one or more accidents will occur during any given month)=0.60.
- P(no accident will occur during any given month)=1-0.60=0.40
We want to calculate the probability that there will be at least four months in which no accidents occur before the fourth month in which at least one accident occurs.
in this case, let k=number of failures before the fourth success
Therefore,
k follows a negative binomial distribution.
Therefore, the probability is:
The required probability is 0.289792.
