What is the midpoint between (-3,-2) and (4-7)
The midpoint between the given figures are -2.5 and 5.5 respectively.
What is a midpoint ?A midpoint is defined as that particular point that divides two separate figures into two equal halves or the centre of two endpoints on a number line.
That is;
point a + point b/2
The figures given are :
Point a = -3
Point b = -2
= -3 + -2/ 2
= -5/2
= -2.5
For points 4 and 7 ;
= 4 + 7 / 2
= 11/2
= 5.5
Therefore, the middle or midpoint of -3 and -2 is -2.5 and the midpoint for 4 and 7 is 5.5.

What is the equation of h(x) in vertex form?
h(x) = (x + 2)2 − 3
h(x) = (x + 1)2 − 2
h(x) = (x − 1)2 + 2
h(x) = (x − 2)2 + 3
The quadratic function of h (x) in vertex form will be as h(x) = (x + 2)² − 3
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
Given that the values of x and h (x) for the quadratic function is given by;
x = -3, -2, -1, 0, 1, 2, 3,
h (x) = -2, -3, -2, 1, 6, 13, 22
Consider the quadratic function as;
h (x) = ax² + bx + c
Now Substitute x = -3 and h (x) = -2 in quadratic function we get;
h (x) = ax² + bx + c
- 2 = a × (-3)² + b × -3 + c
- 2 = 9a - 3b + c
And, Plug x = -2 and h (x) = -3 in function we get;
h (x) = ax² + bx + c
- 3 = a × (-2)² + b × -2 + c
- 3 = 4a - 2b + c
And, plug x = -1 and h (x) = -2 in function we get;
h (x) = ax² + bx + c
- 2 = a × (-1)² + b × -1 + c
- 2 = a - b + c
After solving we get:
a = 1 , b = 4 and c = 1
Then
h (x) = ax² + bx + c
h (x) = 1 × x² + 4x + 1
h (x) = x² + 4x + 1
h (x) = x² + 4x + 4 - 4 + 1
h (x) = (x + 2)² - 3
Hence, The quadratic function of h (x) in vertex form will be as h(x) = (x + 2)² − 3

on average, 12 customers use the bank's atm during the noon lunch hour. what is the probability that exactly 10 customers will use the atm during the next noon lunch hour? assume the poisson distribution applies.
The probability that exactly 10 customers will use the atm during the next noon lunch hour is 0.0948
How to determine the probability the number of customers is 10From the question, we have the following parameters:
Average number of customers = 12
Number of customers = 10
The above parameters means that:
x = 10
λ = 12
The probability of a Poisson distribution is represented as
P(x) = λˣe⁻λ/x!
This gives
P(x = 12) = 10¹² * e⁻¹⁰/12!
Evaluate
P(x = 12) = 10¹² * e⁻¹⁰/479001600
Solving further, we have
P(x = 12) = 0.0948
Hence, the probability is 0.0948

The values of x and y in the triangle are 15 and 88 degrees.
How to find the angles of a triangle?A triangle is a polygon with 3 sides. The sum of angles in a triangle is 180 degrees.
A triangle can be classified base on its sides and angles as equilateral triangle, isosceles triangle and scalene triangles.
An equilateral triangle has three of its sides and angles equal to each other.
An isosceles triangle has 2 sides and angles equal to each other.
A scalene triangle has no sides equal to each other.
Therefore,
The other triangle on the left side is an equilateral triangle.
Therefore, all it sides and angles are equal.
Hence, each angle of the triangle is 60 degrees.
A traversal line cut across the sides of the parallel lines of the triangles formed.
Therefore,
60° = 4x
x = 60 / 4
x = 15
Therefore,
60 + y + 32 = 180(sum of angles in a triangle)

When the summer started, Janie needed to fill her empty pool. At first, she used a garden hose to fill the pool, but this was taking too long. She got tired of watching the pool fill so slowly, so she turned off the water and went for a walk. She spotted a truck in the neighborhood that was filling pools and flagged them down to come fill her pool too. They were able to fill the pool at a faster rate. Which graph best represents this situation?
The statement mentions that the pool started empty, which implies that the graph must start at the point (0,0).
Then, the pool slowly filled, so the amount of water in the pool remained constant when Janie turned off the water and went for a walk.
Finally, thanks to a truck in the neighborhood the pool filled up quickly, and when it was filled the amount of water remained constant.
Therefore, the graph that best represents this situation is the one shown in option B.

The coordinates of the triangle FGH after dilating by 1/2 is F'(-2, -5/2), G'(-3/2, -1), and H'(-1/2, -3/2)
How to determine the coordinates of FGH after the dilation?From the question, the given parameters are the vertices of Triangle FGH
The vertices are represented as
F(-4, -5), G(-3, -2), and H(-1, -3).
Also, from the question, we have
The scale factor of dilation is
k = 1/2
The above implies that
k represents the scale factor of dilation
The coordinates after the dilation is calculated as
Image of dilation = Vertices of the triangle x Scale factor
Substitute the known values in the above equation
So, we have
Image of dilation = [F(-4, -5), G(-3, -2), and H(-1, -3)] x 1/2
Evaluate the products
So, we have
Image of dilation = F'(-2, -5/2), G'(-3/2, -1), and H'(-1/2, -3/2)
