At a store, customers are randomly selected to participate in a survey. On Friday, there were 500 customers at the store. Out of all those people, 90 were selected to participate in the survey. On Saturday, the store manager expects 700 customers in the store. If the probability of being selected to participate in the survey on Saturday is the same as it was on Friday, how many customers will be selected to participate in the survey on on Saturday?

if point P lies on segment AB with endpoints at A(-5,11) and B(1,5) such that AP:PB = 1:1 then p must have coordinates of?
If the ratio is 1:1 then the point must be a mid-point. Then the coordinate of the mid-point P is (–2, 8).
What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of line, etc.
If point P lies on segment AB with endpoints at A(-5,11) and B(1,5) such that AP:PB = 1:1.
We know that if the ratio is 1:1 then the point must be a mid-point.
Let the coordinate of point P be (x, y)
Then we have
[tex]\rm (x,y) = ( \dfrac{x_1+x_2}{2}, \dfrac{y_1+y_2}{2})\\\\(x,y) = (\dfrac{-5+1}{2}, \dfrac{11+5}{2})\\\\(x,y) = (\dfrac{-4}{2} , \dfrac{16}{2})\\\\(x,y) =(-2, 8)[/tex]
The coordinate of the mid-point P is (–2, 8).

4 if c is greater than or equal to 2
determine the following values of the function
f(-3)= __
f(2)= ___
To determine the values of the function f(x) at specific points, we need to look at the different cases given in the definition of f(x).
Explanation:To determine the values of the function f(x) at specific points, we need to look at the different cases given in the definition of f(x).
If x is less than or equal to 0, then f(x) = 3x + 1. So, f(-3) = 3(-3) + 1 = -8.If x is greater than 0 and less than 2, then f(x) = 2x^2. So, f(2) = 2(2^2) = 8.If x is greater than or equal to 2, then f(x) = 4. So, f(2) = 4.Therefore, f(-3) = -8 and f(2) = 4.

Find the greatest common factor : 25p^2q^3, 15p^2q^2 and 35pq^4
Answer:
The greatest common factor is [tex]5pq^2[/tex].
Step-by-step explanation:
The given expressions are [tex]25p^2q^3[/tex], [tex]15p^2q^2[/tex] and [tex]35pq^4[/tex].
Greatest common factor of two numbers is the greatest number that divides both numbers completely.
Find factors of each expression.
[tex]25p^2q^3=5\times 5\times p\times p\times q\times q\times q[/tex]
[tex]15p^2q^2=3\times 5\times p\times p\times q\times q[/tex]
[tex]35pq^4=5\times 7\times p\times q\times q\times q\times q[/tex]
The common factors are 5,p,q and q. So, the greatest common factor of given expressions is
[tex]G.C.F.=5\times p\times q\times q[/tex]
[tex]G.C.F.=5pq^2[/tex]
Therefore the greatest common factor is [tex]5pq^2[/tex].

he difficulty of graphing a quadratic function varies depending on the form you find it in. We'll start things off relatively easily.
f(x) = a(x – h)2 + k
No, we're not lying to you; that is a quadratic function. Go ahead, multiply it out.
f(x) = ax2 + (-2ah)x + (ah2 + k)
The h and k are constants, so (-2ah) and (ah2 + k) are also constants, which we could call, say, b and c. See, you can trust us, it's totally quadratic.
When you have a parabola written out like f(x) = a(x – h)2 + k, it's in vertex form. With vertex form, you have several pieces of important information thrown at you right away. When you first meet someone, your first impression tends to stick with you. It's the same with this equation.
The sign of a tells you if the parabola opens up or down. If a is positive, it opens up. If a is being a Negative Nancy, the parabola opens down. You also know that the vertex of the parabola is at the point (h, k). Be careful with the sign of h, though.

I believe i understand it but have to ask it would be the common difference is -10 bevause you would take -1-9 and get -10?,
The highest point in Africa is Mount Kilimanjaro in Tanzania, with an altitude of 5895 meters above sea level. The lowest point on the continent is Lake Assal in Djibouti. It is 155 meters below sea level. FInd the difference between the altitudes.
Answer:
6050 meters
Step-by-step explanation:
The difference between the altitudes will be the distance from the highest point of kilimanjaroto the lowest point on lake assai.
This distance will be the distance from the highest point of kilimanjaro to the sea level (5895m) plus the distance from the sea level to the lowest point on lake assai (155m, this distances wont be negative because it is taken as a distance from a point of reference not as a value below 0). Like this:
[tex]5895m+155m=6050m[/tex]

Sophie did an anyonymous survey and collected her friends' credit scores. the scores she found are listed in the table below. what is the mean credit score in this group? (round to the nearest whole point, if applicable.) 682 601 744 674 701 790 676 638 773
a. 698
b. 695
c. 676
d. 701
To find the mean of the data, you will combine all values together and then spread them all out evenly to create one value that represents the data.
In math this involves adding the data together and then dividing the sum by how many pieces of data there are.
682 + 601 + 744 + 674 + 701 + 790 + 676 + 638 + 773 = 6279
6279/9 = 697.66...
The rounded credit score is 698 (Choice A).
Using the mean concept, it is found that the mean credit score in this group is given by:
a. 698
What is the mean?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
In this problem, there are 9 observations, which are:
682 601 744 674 701 790 676 638 773
Hence, the mean is given by:
[tex]M = \frac{682 + 601 + 744 + 674 + 701 + 790 + 676 + 638 + 773}{9} = 698[/tex]
Hence option a is correct.
