Answer:
The distance between two points is √58 or 7.61.
Step-by-step explanation:
In the question we need to find the distance between two points 4,1 and -3,-2 given.
Distance between two points can be found using the formula:
[tex]d(P1,P2) = \sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2}[/tex]
Putting the given points in the formula we get,
x₂ = -3, x₁ = 4, y₂= -2, y₁= 1
[tex]=\sqrt{(-3-(4))^2 + (-2-(1))^2} \\=\sqrt{(-3-4)^2 + (-2-1)^2}\\=\sqrt{(-7)^2 + (-3)^2}\\=\sqrt{49 + 9}\\=\sqrt{58}\\=7.61[/tex]
So, the distance between two points is √58 or 7.61.

Suppose that 7% of the general population has a disease and that the test for the disease is accurate 70% of the time. What is the probability of testing positive for the disease.
Answer:
0.049
4.9 % of probability
Step-by-step explanation:
The probability of having the disease is equal to 7%
The probability of testing positive, having the disease is equal to 70%
We are looking for the probability of testing positive.
For that, we need to multiply the probabilities to find the result
P = (0.07)*(0.7)
P = 0.049
P = 4.9%
Find the area of the shape shown below. (Please try to break down.)
The answer is:
The area of the shape is: [tex]10units^{2}[/tex]
[tex]TotalArea=10units^{2}[/tex]
Why?To solve the problem, we must consider that the shape is formed by two right triangles and a square, so, to calculate its area, we need to calculate the areas of the two triangles and square, and then, add them.
So, we are given the following information:
Smallest triangle:
[tex]base=2units\\height=2units[/tex]
Square:
[tex]base=2units\\height=2units[/tex]
Largest triangle:
[tex]base=4\\height=2[/tex]
CalculationsSmallest triangle:
We can calculate the area of a triangle using the following formula:
[tex]A=\frac{base*height}{2}[/tex]
So, substituting, we have:
[tex]A=\frac{2units*2units}{2}=2units^{2}[/tex]
Square:
We can calculate the area of a square using the following formula:
[tex]A=base*height[/tex]
So, substituting, we have:
[tex]A=2units*2units=4units^{2}[/tex]
Largest triangle:
We can calculate the area of a triangle using the following formula:
[tex]A=\frac{base*height}{2}[/tex]
So, substituting, we have:
[tex]A=\frac{4units*2units}{2}=4units^{2}[/tex]
Now, calculating the area of the entire shape, we have:
[tex]TotalArea=SmallestTriangleArea+SquareArea+LargestTriangleArea\\\\TotalArea=2units^{2} +4units^{2} +4units^{2} =10units^{2}[/tex]
Hence, the area of the shape is: [tex]10units^{2}[/tex]
[tex]TotalArea=10units^{2}[/tex]

Step-by-step explanation:
The expression -3m - [2m + (5 - m)] + 7 was simplified as 2 - 4m. Without simplifying, explain how you can show that it has been simplified correctly.
Answer: It is correctly simplified form.
Step-by-step explanation:
Since we have given that
[tex]-3m-[2x+(5-m)]+7[/tex]
We need to simplify the above expression:
[tex]-3m-2m-5+m+7\\\\=-5m+m+2(\text{gather the like terms})\\\\=-4m+2\\\\=2-4m[/tex]
So, [tex]-3m-[2x+(5-m)]+7=2-4m[/tex]
Hence, it is correctly simplified form.

if amanda got on the bus at 2:40 and got off the bus at 3:15. how long was amanda on the bus
Answer:
35 minutes
Step-by-step explanation:
Answer:
35 minutes
Step-by-step explanation:
She was on the bus for :20 before 3:00 and for :15 after 3:00, for a total of ...
:20 +:15 = :35
That is, 35 minutes.
___
There are 60 minutes in an hour. If you like, you can change an hour to 60 minutes and write the exit time as 3:15 = 2:75. Then you can perform the subtraction
2:75 -2:40 = 0:35
(6-3(cube root of 6)/(cube root of 9)
For this case we must simplify the following expression:

Multiplying the numerator and denominator by[tex](\sqrt [3] {9}) ^ 2[/tex]
[tex]\frac {6-3 \sqrt [3] {6}} {\sqrt [3] {9}} * \frac {(\sqrt [3] {9}) ^ 2} {(\sqrt [3] { 9}) ^ 2} =[/tex]
We rewrite:
[tex]\frac {\frac {6-3 \sqrt [3] {6}} * (\sqrt [3] {9}) ^ 2} {\sqrt [3] {9} * (\sqrt [3] {9 }) ^ 2} =[/tex]
By properties of powers we have that:
[tex]a ^ m * a ^ n = a ^ {m + n}\\\frac {(6-3 \sqrt [3] {6}) * (\sqrt [3] {9}) ^ 2} {(\sqrt [3] {9}) ^ 3} =\\\frac {(6-3 \sqrt [3] {6}) * (\sqrt [3] {9}) ^ 2} {9} =[/tex]
We rewrite, moving the exponent within the radical:
[tex]\frac {(6-3 \sqrt [3] {6}) * \sqrt [3] {9 ^ 2}} {9} =\\\frac {(6-3 \sqrt [3] {6}) * \sqrt [3] {81}} {9} =[/tex]
We can rewrite[tex]3 * 3 ^ 3 = 81[/tex]
[tex]\frac {(6-3 \sqrt [3] {6}) * \sqrt [3] {3 * 3 ^ 3}} {9} =[/tex]
We simplify:

Simplifying we finally have:

answer for a math problem i am stuck on
Answer:
m = 116 and a = 105
Step-by-step explanation:
The angle m and 64 are supplementary angles because line of a straight line separated by another straight line. This means that m + 64 = 180, or m = 116.
The sum of all the angles in a quadralateral like this one is 360. So angle a = 360 - 89 - 50 - 116, or a =105.
Answer:
m=116 a=105
Step-by-step explanation:
there is 360 degrees inside a square, i found M by subtracting 180 - 64, because there is a 180 degree angle on a flat line and it showed the other side has 64 degrees, and since we know that m is 180-64=116, we can find A. take the total of degree of the inside of the square which is 360, and subtract all the other angle degrees from it to find the missing number. 360-89-50-116=A. A= 105 degrees.

A can contains 24 fluid ounces of juice. How many pints of fruit juice does the can contain?
Answer:
The can contains 1.5 pints of fruit juice.
Step-by-step explanation:
A can contains 24 fluid ounces of juice.
We have to convert the amount of juice from ounce to pints.
As we know that 1 fluid ounces = [tex]\frac{1}{16}[/tex] pints or 0.0624 pints.
So 24 fluid ounces = 0.0625 × 24 = 1.5 pints.
Therefore, The can contains 1.5 pints of fruit juice.
The can contain 1.5 pints of fruit juice
How many pints of fruit juice does the can contain?A pint is equal to 16 fluid ounces. That is:
1 pint = 16 fluid ounces
To find out how many pints of juice the can contains, we need to divide the number of fluid ounces by the number of fluid ounces in a pint.
Thus, 24 fluid ounces of juice in pint will be:
24/ 16 = 1.5 pints
Therefore, the can contains 1.5 pints of fruit juice.

Which is the best estimate for the percent that is represented by the shaded portion of the diagram? 30% 36% 38% 40%
Answer:
Three of the boxes out of the eight are shaded.
So, 3/8 is .375 which is around 38%.
Hello there!
In this diagram, there are a total of 8 squares, and 3 of them are shaded. This means that 3/8 of them are shaded, and to find what percent this is, divide 3 by 8 and multiply what you get by 100.
3 divided by 8 = 0.375
0.375 x 100 = 37.5%.
37.5% is closest to 38%, so that is your answer!

8 less than the product of a number n and 1/5 is no more than 95
Answer:
(n/5)-8≤95
Step-by-step explanation:
The solution for the given problem is : [tex]\( n \leq 515 \)[/tex].
Sure, let's solve the problem step by step.
Given: [tex]\( \frac{1}{5}n - 8 \leq 95 \)[/tex]
To solve for [tex]\( n \),[/tex] we'll first add 8 to both sides of the inequality:
[tex]\( \frac{1}{5}n \leq 95 + 8 \)[/tex]
[tex]\( \frac{1}{5}n \leq 103 \)[/tex]
Now, we'll multiply both sides by 5 to isolate[tex]\( n \)[/tex]:
[tex]\( 5 \times \frac{1}{5}n \leq 5 \times 103 \)[/tex]
[tex]\( n \leq 515 \)[/tex]
So, the solution is[tex]\( n \leq 515 \)[/tex]
In conclusion, the solution to the problem is [tex]\( n \leq 515 \)[/tex]. We reached this conclusion by carefully manipulating the inequality step by step to isolate [tex]\( n \).[/tex] This process ensures that our solution is accurate and follows the rules of algebra.

we are required to demonstrate that we understand what represents a function and what does not represent a function by writing a paragraph which can be given as:
We know that functions are mathematical entities that assign unique outputs to given inputs. In other words, a function can't have repeated values in the input repeated x-value.
For example consider the relation {(1,4), (1,5), (2,6), (3,7), (4,8), (5,9)}.
We see that above relation has repeated x-value "1" which is assigned to two different output values 4 and 5. So by definition of function, above relation can't be a function.
