A one-week study revealed that 60% of a warehouse store's customers are women and that 30% of women customers spend at least $250 on a single visit to the store. Find the probability that a randomly chosen customer will be a woman who spends at least $250.

The probability of a randomly chosen customer to be a woman who spends at least $250 is 0.18 or 18%

Step-by-step explanation:

60% of the customers are women, and 30% of the women spend at least $250.

We want to find the probability for a randomly selected customer to be a woman that spends at least $250

first, the probability of a random customer to be a woman is 60% or 0.6 in decimal form.

And 30% of those 60% spend at least $250, so the probability the product of those two, this is:

P = 0.6*0.3 = 0.18

So the probability of a randomly chosen customer to be a woman who spends at least $250 is 0.18 or 18%

answer: c i think

step-by-step explanation:

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
