Answer:
P(1 red gumball and 1 blue balloon) =[tex]\frac{2}{15}[/tex]
Step-by-step explanation:
There are two jars.
One jar has 2 red, 3 green and 1 yellow gumball.So, there are 2+3+1=6 gumballs.
Another jar has 2 blue and 3 purple balloons. Totally there are 2+3=5 balloons.
So,
Probability of drawing 1 red gumball from jar 1 =[tex]\frac{2}{6}[/tex]
Probability of drawing 1 blue balloon =[tex]\frac{2}{5}[/tex]
So, P( 1 red gumball, 1 blue balloon)= [tex]\frac{2}{6} *\frac{2}{5} =\frac{2}{15}[/tex]

Gross domestic product is the economic indicator to measure of all goods and services produced within a given economy in one year
What is Economic indicator ?An economic indicator is a statistic about an economic activity. Economic indicators allow analysis of economic performance and predictions of future performance.
We need to find the which economic indicator is the measure of all goods and services produced within a given economy in one year.
A trade deficit occurs when a country imports more than it exports
A trade surplus is an economic measure of a positive balance of trade, where a country's exports exceed its imports.
GDP measures the monetary value of final goods and services—that is, those that are bought by the final user—produced in a country in a given period of time
Hence, gross domestic product is the economic indicator to measure of all goods and services produced within a given economy in one year

Answer:
Step-by-step explanation:
They all give 8r so that is not the distinguishing characteristic.
The first one in column A gives
12r + t - 4r + 6t
12r - 4r + t + 6t
8r + 7t
This is the third one in column B
2nd one in Column A
12r + 2t - (4r + 10t) Remove the brackets
12r + 2t - 4r - 10t Pay close attention to 10t becoming -10t. The minus sign effects both terms inside the brackets.
12t - 4t + 2t - 10t Combine
8r - 8t Now take out the common factor (8)
8(r - t) That's the top one in column B
3rd one in column A
12(r + t) - 6(r +t) + 4(r + t) - 2(r+t) They all have r+t so r + t is a common factor)
(r+t) [12 - 6 + 4 - 2] Combine
(r + t ) [ 8 ]
This is the second one in column B
The trick here is to look out for common factors. Don't remove the brackets. But it takes a bit of practice before you know that
Ifa=12 and 120% of a is equal to 80% of b, then what is
a+b?
Rsm question
Answer:
a + b = 30
Step-by-step explanation:
If we convert the percentages to decimals (120% = 1.2 & 80% = 0.8), we can use this equation to find B: 1.2A = 0.8b
Since we know a, we then have 1.2 * 12 = 0.8b
Solving for B gives us b = 18
12 + 18 = 30
Use the interactive to graph these numbers on the number line. –4, 3, 0. 5, 1 Which number is closest to zero?.
The number closest to 0 is the number whose absolute difference from 0 is the smallest
0.5 is the closest number to 0
How to determine the closest to 0The numbers are given as:
–4, 3, 0. 5, 1
Calculate their absolute difference with 0
|-4 - 0| = 4
|3 - 0| = 3
|0.5 - 0| = 0.5
|1 - 0| = 1
The smallest absolute difference is 0.5

What polynomial must be subtracted from 2x^3 − x^2 + 4x − 5 so that the difference is
x^3 + 2x − 9?
Answer:
-x^3 + x^2 - 2x - 4
Step-by-step explanation:
You have to subtract
Let o = the polynomial
So you know 2x^3 - x^2 + 4x + 5 - o = x^3 + 2x - 9
Now you do 2x^3 - x^3 = x^3
then you -x^2 + answer = 0
you need to cancel it out
to cancel, you found out that it is x^2
Now you need to make from 4x to 2x.
To do that, you do 4x - 2x and you get 2x
Lastly you need to change -5 to 9. To do that you add -4.
Now since it is subtraction you have to distribute
2x^3 - x^2 + 4x - 5 -(x^3 - x^2 + 2x + 4)
= 2x^3 - x^2 + 4x + 5 - x^3 + x^2 -2x -4
= x^3 -2x + 9

The polynomial that is prime is given by Option C: [tex]10x^2 - 4x +3x +6[/tex]
What are prime polynomials?Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomial.
(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)
Checking all the listed polynomials for them being prime or not:
Case 1: [tex]x^3+3x^2+2x+6[/tex]Rewriting it as:
[tex]x^3+3x^2+2x+6 = x^2(x+3) + 2(x+3) = (x^2 + 2)(x+3)[/tex]
shows that this polynomial has factors. Thus, it isn't prime polynomial
Case 2: [tex]x^3 + 3x^2 -2x -6[/tex]Rewriting it as:
[tex]x^3 + 3x^2 -2x -6 = x^2(x+3) -2(x+3) = (x^2-2)(x+3)[/tex]
shows that this polynomial has factors. Thus, it isn't prime polynomial
Case 3: [tex]10x^2 - 4x +3x +6[/tex]We can rewrite it as:
[tex]10x^2 -4x + 3x -6 = 10x^2 -x -6 = f(x) \: \rm (say)[/tex]
This polynomial is prime polynomial as it is irreducible in terms of polynomials having their coefficients as integers.
Case 4: [tex]10x^2 -10x + 6x - 6[/tex]
It can be factored as:
[tex]10x(x-1) + 6(x-1) = (x-1)(10x-6)[/tex]
This is not a prime polynomial.

A surveyor wants to use similar triangles to determine the distance across a lake as shown at the right. What is the distance d across the lake?
A. 75ft
B. 80ft
C. 85ft
D. 90f
Base on the similarity principle of triangles, the distance d across the lake as shown is 90 ft.
Similar triangle theoremsTwo triangles are similar if they are only difference in size but have the same shape.
In similar triangles, corresponding sides are always in the same ratio.
Therefore, let's create a proportion from the triangles since they are similar.
40 / d = 20 / 45
cross multiply
45 × 40 = 20d
1800 = 20d
divide both sides by 20
1800 / 20 = 20d / 20

A city starts with a population of 500,000 people in 2007. Its population declines according to the equation
P(t) = 500,000e -0.099t
where P is the population in t years later. Approximately when will the population be half the initial amount?
Answer:
2014
Step-by-step explanation:
Given the exponential growth function :
P(t) = 500,000e^-0.099t
Where P is population in t years later
When the population will 1/2 the initial amount
1/2 the initial amount = 1/2 * 500,000 = 250,000
P(t) = 250,000
250,000 = 500000e^-0.099t
250,000/500000 = e^-0.099t
In(0.5) = - 0.099t
t = −0.69314 / - 0.099
t = 7.0014
t = 7
Year which population = 500,000 = 2007
Hence, half the population will be attained on (2007 + 7) = 2014
After 7 years population of the city will be half of the initial amount.
Population function:
[tex]P(t) = 500000 e^{-0.099t}[/tex]
Initial population means population at t=0
P(0) = 500000
Half of initial population = 250000
So, we need to calculate the time t when the population will be half of the initial amount.
[tex]250000= 500000 e^{-0.099t}\\\\e^{-0.099t} = \frac{1}{2}[/tex]
Taking log both sides
-0.099t (log e)= log (1/2)
What is the logarithm of e?The logarithm of e is 1 when considering the base of the log as e.
So, -0.099 t= -0.693
t=7
Therefore, After 7 years population of the city will be half of the initial amount.
