In a survey at a shoe store, 200 customers were asked whether they have
1 answer:
Answer:
option D
Step-by-step explanation:
in a shoe store survey there are 200 customers.
given in the table is that people using basketball shoes, not using basket shoes and then there is also classification of people using running or non running shoes.
We have been asked what percentage of people have basketball shoes.
People having basket ball shoes = 0.23 × 200 + 0.31 ×200
= 108
percentage of people wearing basket ball shoe =
= 54 %
we can also find it by directly adding the given value and multiplying it by 100
= 0.23+0.31 = 0.54 ×100 = 54%
hence, the correct answer is option D

Answer:
(You only need to give one solution)
Step-by-step explanation:
We have the following equation
First, we need to foil out the parenthesis
Now we can combine the like terms
Now, we need to factor this equation.
To factor this, we need to find a set of numbers that add together to get -3 and multiply to give us -4.
The pair of numbers that would do this would be 1 and -4.
This means that our factored form would be
As the first binomial is a difference of squares, it can be factored futher into
Now, we can get our solutions.
The first binomial will produce two complex (Not real) solutions.
So our solutions to this equation are
The first thing we are going to do for this case is define variables.
We have then:
x: number of days
y: number of pages remaining.
We write the linear equation that models the problem:
The intersection with the vertical axis is:
We evaluate x = 0:
We get the point:
The intersection with the horizontal axis is:
We evaluate y = 0:
We get the point:
