Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (w.y) be the unknown
Reil [10]

Answer:

<h2><em>(3,6)</em></h2>

Step-by-step explanation:

Given two coordinates (x₁,x₂) and (y₁,y₂), their midpoint (w,y) is expressed as:

M(X,Y) = (\dfrac{x_1+w}{2},  \dfrac{y_1+y}{2})

From the question, we are given the midpoint (X,Y) to be (2,2) and one endpoint as (1, -2) and we are to find the other end point expressed as (w,y). From the coordinates given, i can be seen that X = 2, Y =2, x₁ = 1 and y₁ = -2

Substituting the given end points into the given formula to get the other end points, we will have;

X = \dfrac{x_1+w}{2} \\2 =  \dfrac{1+w}{2} \\cross\ multiply\\4 = 1+w\\w = 4-1\\w = 3

Similarly;

Y = \dfrac{y_1+y}{2} \\2 =  \dfrac{-2+y}{2} \\cross\ multiply\\4 = -2+y\\y = 4+2\\y = 6

<em>Hence the other endpoint (w, y) is (3,6)</em>

Water use in the summer is normally distributed with a mean of 311.4 million gallons per day and a standard deviation of 40 mill
r-ruslan [8.4K]

Answer: 0.965

Step-by-step explanation:

Given : Water use in the summer is normally distributed with

\mu=311.4\text{ million gallons per day}

\sigma=40 \text{ million gallons per day}

Let X be the random variable that represents the quantity of water required on a particular day.

Z-score : \dfrac{x-\mu}{\sigma}

\dfrac{350-311.4}{40}=0.965

Now, the probability that a day requires more water than is stored in city reservoirs is given by:-

P(x>350)=P(z>0.965)=1-P(z

We can see that on comparing the above value to the given P(X > 350)= 1 - P(Z < b) , we get the value of b is 0.965.

A rectangular exercise mat has a perimeter of 36 feet . The length mat is twice the width. Write and solve an equation to determ
Goshia [24]
ANSWER

72 square feet

EXPLANATION

The perimeter of a rectangle is given by:

P= 2l+2w

It was given that, the perimeter of the rectangular mat, is 36 feet.

36= 2l+2w

Divide through by 2.

18 = l + w...(1)

It was given also that, the length of the mat is twice its width.

This implies that,

l = 2w ...(2)

Put equation (2) into equation (1) to get,

18 = 2w + w

18 = 3w

w = 6 \: ft

This means that the length is 12 ft.

The area of the rectangular mat is

A = l \times w

A = 6 \times 12 = 72 {ft}^{2}

The expression 50 can be simplified to
puteri [66]

Answer:

25

Step-by-step explanation:

The first step in simplifying the expression of the square root of 50 involves finding factors of 50. This just means we are trying to find two whole numbers that, when multiplied, equal 50. Since 50 is an even number, 2 is going to be a factor, and so we can rewrite 50 as 2 times 25.
