Since she wrote the numbers 1-100, we know that the probability for one number is 1/100.
If she selects a number without looking, it's a 1/100 chance she'll pull out one specific number.
However, here we need to find the probability of a number below 5. There are four numbers below 5 from the range to 1-100 and they are 1, 2, 3, and 4.
Therefore, since there are 4 numbers below 5, we have a 4/100 chance of Jane pulling out a number below 5.
In simplified terms it would be [tex]\frac{1}{25}[/tex]
In decimal form, it would be 0.04

The solution of the simultaneous linear equations shown below is 2x - y=12 2x+y=13
Answer:
(6.25, 0.5 )
Step-by-step explanation:
2x - y = 12 → (1)
2x + y = 13 → (2)
Add the 2 equations term by term to eliminate y
4x + 0 = 25
4x = 25 ( divide both sides by 4 )
x = 6.25
substitute x = 6.25 into either of the 2 equations and solve for y
substituting into (2)
2(6.25) + y = 13
12.5 + y = 13 ( subtract 12.5 from both sides )
y = 0.5
solution is (6.25, 0.5 )
A pet supply company makes a small bag that holds 2 pounds of dog food. They want to make a bag for large dogs that holds 40 pounds of dog food. By approximately what factor will the surface area of the bag increase? Round answer to nearest tenth. Show your work.
The increase in surface area of the bag is by a factor of 20.
ScalingScaling is the increase or decrease in the size of an object or figure by a factor k, so as to create an image.
Given that the bag size is increased so as to carry more food, hence:
Scale factor = 40 pounds / 2 pounds = 20

This integral can be approximated by the following Riemann sum:
[tex]A = \Sigma\limits_{i=0}^{2} \left\{(x_{i+1}-x_{i})\cdot x_{i}\cdot h''(x_{i})+\frac{1}{2}\cdot (x_{i+1}-x_{i})\cdot [x_{i+1}\cdot h''(x_{i+1})-x_{i}\cdot h''(x_{i})] \right\}[/tex]

Then, the approximate value of the integral is:
[tex]A = \frac{1}{2}\cdot \{(2-1)\cdot [(2)\cdot 2+(1)\cdot (-5)]+(3-2)\cdot [(3)\cdot 1+(2)\cdot 2]+(4-1)\cdot [(4)\cdot 2+(3)\cdot 1]\}[/tex]

Find the elapsed time.
Start: 11:55 A.M.
End: 5:10 P.M.
Answer:
5 hours and 15 minutes
Step-by-step explanation:
From 11:55 A.M. to 12:00 P.M. is 5 minutes.
From 12:00 P.M. to 12:10 P.M. is 10 minutes.
From 12:10 P.M. to 5:10 P.M. is 5 hours.
If you add all of that up to get the time that has elapsed, you will get 5 hours and 15 minutes.

Circle T is defined by the equation (x + 5)2 + (y - 2) = 81. Which of the following shows the location of the center of Circle T and the radius of this
circle?
A T is located on (-5, 2); radius = 9 units
B T is located at (5,-2); radius = 9 units
C T is located at (-5, 2); radius = 81 units
D T is located at (5,-2); radius = 81 units
Answer:
A) T is located on (-5, 2); radius = 9 units
Step-by-step explanation:
eqn of circle= (x-a)^2 + (y-b)^2 = r^2
where (a,b) is centre of circle.
(x+5)^2 = (x - (-5) )^2
(y-2)^2 = (y - (2) )^2
(-5,2)
r^2 =81
r = sqrt of 81

Solve for x and y
6/x+2y + 5/x-2y = -3 ;
3/x+2y + 7/x-2y = -6
Step-by-step explanation:
Let
{1/(x+2y)} = u -----Eqn(1)
{1/(x-2y)} = v ------Eqn(2)
So, given equation can be rewritten as
⇛6u + 5v = -3 ---Eqn(3)
⇛3u + 7v = -6 -----Eqn(4)
On multiply equation (4) by 2, we get
⇛6u + 14v = -12 -----Eqn(5)
On subtracting equation (3) from equation (5), we get
⇛9v = -9
⇛v = -9/9
⇛v = -1 ----Eqn(6)
Put value of v in equation (3), we get
6u + 5v = -3
⇛6u + 5 * (-1) = -3
⇛6u -5 = -3
⇛6u = -3 + 5
⇛6u = 2
⇛u = 2/6
⇛u = (2÷2)/(6÷2)
⇛u = 1/3 -----Eqn(7)
Now, substituting value of u and v in equation (1) and equation (2), we get
{1/(x+2y)} = 1/3 and {1/(x-2y)} = -1
⇛x + 2y = 3 -----Eqn(8)
⇛x - 2y = -1 -------Eqn(9)
Now, add equation (8) and equation (9) , we get
⇛2x = 2
⇛x = 2/2
⇛x = 1 -----Eqn(10)On substituting x = 1 in equation (8), we get
x + 2y = 3
⇛ 1 + 2y = 3
⇛2y = 3 - 1
⇛2y = 2
⇛y = 2/2
⇛y = 1 ------Eqn(11)Therefore, x = 1 and y = 1
Answer: Hence the value of x and y is 1 and 1.

Use arithmetic to solve the problem.
Write an equation to solve the problem.
2. Explain the steps you could use to solve 3y + 6 = 30 to find y.
Answer:
A. The price would be 24 because 28-4 dollars is 24
B. How much a cost altogether and the fact that he has two kids
C. You can take the total of the price of all their tickets combined to subtract 24 and you would get 52 so so I slice and a half in and you have the answer
D 26 dollars each
E. 76-24=52 52/2=26
Step-by-step explanation:
Can someone explain just 17-28??
Answer:
you solve these by plugging the numbers into pythagorean theorem which is
a^2 + b^2 = c^2 (a squared plus b squared equal c squared)
C is the hypotenuse which is the longest side across from the right angel (assuming all these problems are for right triangles)
so 17 would be 9.5^2 + 3.8^2 = c^2
So 90.25 + 14.44 = c^2
104.69=c^2
Then to solve for c take the square root of each side and get
10.23=c
To do the other ones where a or b doesn’t have a value, it’s almost the same but you just have to plug in the variables in different places and solve it

The area of a rectangle is 5 x cubed 19 x squared 6 x minus 18 with length x 3. Using synthetic division, what is the width of the rectangle? 5 x squared 4 x minus 6 5 x squared 34 x 108 StartFraction 306 Over x 3 EndFraction 5 x cubed 4 x squared minus 6 x 5 x squared 34 x 108 StartFraction 306 Over x minus 3 EndFraction.
The area of the rectangle is the product of its dimensions.
The width of the rectangle is [tex]5(19x^2 + 6x - 18)[/tex]
How to calculate the width of the rectangleThe area of the rectangle is given as:
[tex]Area = 5x^3(19x^2 + 6x - 18)[/tex]
The length of the rectangle is given as:
[tex]Length =x^3[/tex]
So, we have:
[tex]Area = Length * Width[/tex]
Substitute known values
[tex]5x^3(19x^2 + 6x - 18)= x^3* Width[/tex]
Divide through by x^3
[tex]5(19x^2 + 6x - 18)= Width[/tex]
Rewrite the equation as:
[tex]Width = 5(19x^2 + 6x - 18)[/tex]
Hence, the expression that represents the width of the rectangle is [tex]5(19x^2 + 6x - 18)[/tex]
