A bag contains 70 pencils out of which 15 are green and 30 are blue. How many pencils of other colour are in the bag. A pencil is selected from a bag at random .What is the probability that it is blue?
Answer:
a) There are 25 pencils of other colour in the bag.
b) P(Blue) = 3/7
Step-by-step explanation:
A bag contains 70 pencils out of which 15 are green and 30 are blue.
a) How many pencils of other colour are in the bag?
This is calculated as:
70 - (15 + 30)
= 70 - 45
= 25 pencils
Hence, there are 25 pencils of other colour in the bag.
b) A pencil is selected from a bag at random .What is the probability that it is blue?
P(Blue) = Number of Blue pencils/Total number of Pencils
P(Blue) = 30/70
P(Blue) = 3/7
-2(p - 1) = 15 helllp plss slol
Answer:
-13/2
Step-by-step explanation:
Answer:
P = -6.5
Step-by-step explanation:
Multiply -2 x p and -2 x -1
The equation now is -2p + 2 = 15
Subtract the 2 to both sides to cancel it out
The equation now is -2p = 13
Divided both sides by -2 to isolate the p variable
p = -6.5
You can check your answer by subtracting -6.5 by -1 (which equals -7.5)
And then multiply -7.5 by -2 which equals 15

Answer:
A. 4.5
Step-by-step explanation:
I need you to do all plssss
Answer:
9 = probably D(maybe A)
I'm not sure what the answer is for #9 but I think it is most likely D. A is multiply 6 by 4 which would be substituting the value of w, for w. D is adding 2 to 40 which is combining like terms.
10 = C, 65
40+p
40+25
65

Answer:
Answer Choice C
Step-by-step explanation:
Because it is dilated by a factor of 3
Consider the sequence whose first five terms are shown. -59 ,-67 ,-65 ,-53 ,-31 ,... The first term is ____ To calculate the second term, add _____ To calculate each additional term, increase the amount added by _____ (the _____ are blanks)
Step-by-step explanation:
The sequence is as follows :
-59 ,-67 ,-65 ,-53 ,-31 ,...
The first term = -59
The second term = -67
Common difference = second term - first term
[tex]=-67-(-59)\\\\=-8[/tex]
To calculate the second term add (-8).

So how do i do like Rule: y=x+3 and the boxes are like X Y ? 4 ? 8 ? 5 like how
Answer:
X: 1 5 2
Y: 4 8 5
Step-by-step explanation:
Given
[tex]Rule: y = x + 3[/tex]
X: ? ? ?
Y: 4 8 5
Required
Fill in the ?'s
We have that:
[tex]y = x + 3[/tex]
When y = 4; the rule becomes
[tex]4 = x + 3[/tex]
Subtract 3 from both sides
[tex]1 =x[/tex]
[tex]x =1[/tex]
When y = 8; the rule becomes
[tex]8 = x + 3[/tex]
Subtract 3 from both sides
[tex]5= x[/tex]
[tex]x =5[/tex]
When y = 5; the rule becomes
[tex]5 = x + 3[/tex]
Subtract 3 from both sides
[tex]2 = x[/tex]
[tex]x = 2[/tex]
So, the complete table is:
X: 1 5 2
Y: 4 8 5

Cos30*cos50+sin30*sin50
9514 1404 393
Answer:
cos(20°)
Step-by-step explanation:
The angle difference formula for cosine is ...
cos(α -β) = cos(α)cos(β) +sin(α)sin(β)
If we let α = 50° and β = 30° then this matches the given expression:
cos(50° -30°) = cos(50°)cos(30°) +sin(50°)sin(30°) = cos(20°)
Sketch the graph of 2y=f(3x-6) -2
Um i think 2yyyy =f 3x-6
The required graph is attached below, which represents the given function f(x)= 3x - 6y - 2.
The below graph of the function f(x) = 3x - 6y - 2 represents a straight line in a two-dimensional coordinate system.
The equation is in standard form, where x and y are variables and the equation is equal to a constant value (-2 in this case).
To graph this equation, we can rearrange it to the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.
By isolating y in the equation, we get y = (3/6)x - 2/6, which simplifies to y = (1/2)x - 1/3.
The slope of the line is 1/2, meaning for every increase of 1 in the x-coordinate, the y-coordinate increases by 1/2.
The y-intercept is -1/3, which is where the line crosses the y-axis.

What is Least Common Multiple?Least Common Multiple is the meaning of the abbreviation LCM. The lowest number that may be divided by both numbers is known as the least common multiple (LCM) of two numbers. It can also be computed using two or more numbers. Finding the LCM of a given collection of numbers can be done in a variety of ways.
In mathematics, the least common multiple is sometimes referred to as LCM or the lowest common multiple. The smallest number among all the common multiples of the provided numbers is the least common multiple of two or more numbers.
Given:
Matt practice every fourth day.
I practice on 3rd days
Now, to find the first date on which they both have practice we have to find the LCM
So, 4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40
3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
Hence, On 12th they both practice together.

15 points and BRAINLIEST Alyssa invested $500 into an account. The value of the account after t years can be found using the function r(t) = 500(1.068). What is the percent annual rate of change
in the value of the account?
Answer:
annual rate: r = 0.068
Step-by-step explanation:
The formula is r(t) = P(1+r)^t
Since the time is already in years we just have to solve for the rate
1 + r = 1.068
r = 0.068
The rate of change in the value of account is 0.068
What is rate of change?
'Rate of change is used to mathematically describe the percentage change in value over a defined period of time.'
According to the given problem,
Annual rate:
r = 0.068
The formula is r(t) = [tex]P( 1 + r )^{t}[/tex]
Therefore, solving for the rate
⇒ 1 + r = 1.068
⇒ r = 0.068

The two stadiums with the largest capacities are Marshfield Stadium and Bowden Stadium. Marshfield Stadium has a capacity of 7,675 more than Bowden. If the combined capacity for the two stadiums is 210,355, find the capacity for each stadium.
Answer: Capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.
Step-by-step explanation:
Let x = Capacity of Marshfield Stadium.
y = Capacity of Bowden.
As per given, we have
x - y = 7,675 (i)
x+y = 210,355 (ii)
2x = 218030 (iii)
[tex]\Rightarrow\ x= \dfrac{218030}{2}\\\\\Rightarrow\ x= 109015[/tex]
Put value of x in (i) , we get
109015 - y = 7675
⇒ y= 109015 - 7675
⇒ y= 101,340
Hence, capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.
