The probability that Laura does not win the prize is 0.9657
What is Probability?
The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
The value of probability lies between 0 and 1
Given data ,
Let the probability that Laura wins be = P ( x )
So , the probability that Laura does not win is = 1 - P ( x )
Let the total number of raffle tickets to be sold is = 350 raffle tickets
The number of tickets Laura bought = 12 raffle tickets
Therefore , the probability that Laura wins the prize =
number of tickets Laura bought / total number of raffle tickets
The probability that Laura wins the prize P ( x ) = ( 12/350 )
Now ,
The probability that Laura does not win is = 1 - P ( x )
The probability that Laura does not win = 1 - ( 12/350 )
The probability that Laura does not win = ( 350 - 12 ) / 350
The probability that Laura does not win = 338 / 350
The probability that Laura does not win = 0.9657
Hence , The probability that Laura does not win the prize is 0.9657

A triangle has sides with lengths of 16 millimeters, 20 millimeters, and 25 millimeters. Is it a
right triangle?
Answer:
No
Step-by-step explanation:
If it is a right triangle, then the Pythagorean theorem must work.
a^2 + b^2 = c^2 (a and b are the shorter sides and c is the longest)
16^2 + 20^2 = 25^2
256 + 400 = 625
656 = 625

The area of the entire figure below is 1 square unit.
What is the area of the striped rectangle?
Answer:
3/4 * 2/5
Step-by-step explanation:
Areas is L * W
(1/5 + 1/5) * (1/4 + 1/4 + 1/4) = 2/5 * 3/4
Answer:
3/10
Step-by-step explanation:
The area will be the length of the striped rectangle multiplied by the width of the striped rectangle.
The length will be 1/4 + 1/4 + 1/4 = 3/4 and the width will be 1/5 + 1/5 = 2/5.
Now just multiply 3/4 by 2/5 and you'll get 6/20 which in its simplest form is 3/10.

help???????????????????
Answer:
Please check the explanation.
Step-by-step explanation:
Part a)
Given
m∠ABD = (7q - 46)°m∠CBD = (3q + 6)°It is clear that m∠ABD and m∠CBD lie on a straight line.
Thus, the sum of m∠ABD and m∠CBD will be 180°.
Hence,
m∠ABD and m∠CBD are supplementary angles.
Part b)
As m∠ABD and m∠CBD are supplementary angles, so the sum of m∠ABD and m∠CBD will be 180°.
Thus,
m∠ABD + m∠CBD = 180°
substitute m∠ABD = (7q-46)° and m∠CBD = (3q + 6)°
(7q-46)° + (3q + 6)° = 180°
Part c)
Given the equation
(7q-46)° + (3q + 6)° = 180°
Combining the like terms
7q + 3q - 46 + 6 = 180
10q - 40 = 180
10q = 180 + 40
10q = 220
divide both sides by 10
10q/10 = 220/10
q = 22
Therefore, the value of q = 22
Part d)
As
m∠ABD = (7q-46)°
substituting q = 22
m∠ABD = 7(22) - 46
= 154 - 46
= 108°
also
m∠CBD = (3q + 6)°
substituting q = 22
m∠CBD = 3(22) + 6
= 66+6
= 72°
Therefore,
m∠ABD = 108°m∠CBD = 72°Jeffery bought 203 sheets of stickers. Each sheet has a dozen stickers. He gave away 907 stickers to his family and friends on Valentine’s Day. How many stickers does Jeffery have remaining?

Answer:
(a) m = 10
(b) n = 160
Step-by-step explanation:
To rewrite the expression in the manner indicated, write an equation that sets the given expression equal to the desired expression. Then solve for the variable value. The distributive property and the usual rules of exponents apply.
The rules of exponents you can use here are ...
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
a^0 = 1
__
(a) 2^101 +2^103 = m×2^100
2^(101-100) +2^(103-100) = m × 2^(100-100) . . . . . . . multiply by 2^(-100)
2^1 +2^3 = m
2 + 8 = m
m = 10
__
(b) 2^101 +2^103 = n×4^48
2^101 +2^103 = n×(2^2)^48 . . . . . substitute 4 = 2^2
2^101 +2^103 = n×2^96 . . . . . . . . simplify
2^5 +2^7 = n . . . . . . . . . . . . . . . . . as above, multiply by 2^(-96)
32 +128 = n
n = 160
_____
Additional comment
The rules of exponents tell you that ...
(m × 2^100) × 2^-100 = m × 2^(100 -100) = m × 2^0 = m
This is effectively the same as dividing by 2^100. You're doing the same thing you would do to solve any linear equation: divide by the coefficient of the variable.

Answer:
Undefined
Step-by-step explanation:
0=0
Answer:
0
Step-by-step explanation:
Combine the like terms 9x-2x = 7x
Subtract the numbers 11-5 = 6
Combine the like terms again 4x+3x = 7x
Subtract 6 from both sides of the equation 6-6 = 0 6-6 = 0
Simplify 7x = 7x

Which is shorter? 3/6 of a minute or 2/6 of an hour?
Answer:
3/6 of a minute
Step-by-step explanation:
3/6 can also be simplified to 1/2. So, 1/2 of a minute is 30 seconds. 2/6 can be simplified to 1/3. So, 1/3 of an hour is 20 minutes. 30 seconds is very much shorter than 20 minutes. Thus, 3/6 of a minute is shorter than 2/6 fo an hour.

Hi. I need help with these questions (see image)
Please show workings.
Answer a and b
Answer:
see explanation
Step-by-step explanation:
Using the chain rule along with standard derivatives
Given
y = f(g(x)) , then
[tex]\frac{dy}{dx}[/tex] = f'(g(x)) × g'(x)
[tex]\frac{d}{dx}[/tex] (sinx) = cosx , [tex]\frac{d}{dx}[/tex] (cosx) = - sinx
(a)
y = sin x²
[tex]\frac{dy}{dx}[/tex] = cos x² × [tex]\frac{d}{dx}[/tex] (x² )
= cos x² × 2x
= 2xcosx²
(b)
y = cos4x³
[tex]\frac{dy}{dx}[/tex] = - sin4x³ × [tex]\frac{d}{dx}[/tex] (4x³ )
= - sin4x³ × 12x²
= - 12x²sin4x³

The weight of Jack is 30kg 500g. The weight of Dereck is 28kg 700g. What is their total weight? Also, find the difference of their weight?
Answer:
Below.
Step-by-step explanation:
30 kg 500g + 28kg 700g
= 58kg + 1200g
= 59kg 200g.
Difference
= 30 kg 500g - 28kg 700g

Brenda's school is selling tickets to a spring musical. On the first day of ticket sales the school sold 3 senior citizen tickets and 9 child ... The school took in $67.00 on the second day by selling 8 senior citizen tickets and 5 child tickets. What is the price each of one senior citizen ticket and one child ticket?
Given data
let senior citizens be x
and children be y
so
3x+9y= 75--------------1
on the second day
8x+5y= 67------------2
solve 1 and 2 above
3x+9y= 75 X8
8x+5y= 67 X3
24x+72y=600
-24x+15y=201
0x+57y= 399
divide both sides by 57
y= 399/57
y= $7
put y= 7 in eqn 1 above
3x+9*7= 75
3x+63= 75
3x=75-63
3x=12
x= 12/3
x= $4

A c ompany purchased 3,128 bottles of water.Each departments needs 55 bottles.Which compatible numbers provide a better estimate for the number of departments that can get the bottles needed 3,000 divided 60 or 3,000 divided 50? Explain.Then make the estimate.
Answer:
3,000 divided 60 are the compatible numbers, and the estimate is 50.
Step-by-step explanation:
Compatible numbers can be described as numbers which are close in value to the actual numbers and can easily be added, subtracted, multiplied, or divided mentally.
From the question, 3,000 divided 60 are the compatible numbers that provide a better estimate for the number of departments that can get the bottles because 55 can be rounded up to 60.
The estimate will therefore be as follows:
Estimate = 3,000 / 60 = 50
