2/5 - 1/15 show your work
Answer:
0.34
Step-by-step explanation:
2/5 = 0.4
1/15 = 0.06
0.4-0.06=0.34
write in slope intercept form
Answer:
[tex]-\frac{3}{5}[/tex]
The slope is -3/5
Step-by-step explanation:
Answer:
y=3/5x-2
Step-by-step explanation:
Right now, this equation is in standard from or Ax^2 + Bx = C and you need to convert it to slope-intercept from which is y=mx+b where m is the slope and b is the y-intercept
Convertion
3x-5y=10 Subtract 3x from both sides
-5y=-3x+10 Divide all terms by -5
You get
y=3/5x-2
Assume there is a 50% chance of having a boy. Find the probability of
exactly two boys in three births.
Answer:
0.375
Step-by-step explanation:
Given that there is 50% chance of having a boy in a single birth.
Let it be represented by p, so
p=50%=0.5
According to Bernoulli's theorem, the probability of exactly r success in n trials is
[tex]P(r)=\binom {n}{ r} p^r(1-p)^{n-r}[/tex]
where p is the probability of success.
So, the probability of exactly 2 boys (success) in a total of 3 birth (trials) is
[tex]P(r=2)=\binom {3}{ 2} p^2(1-p)^{3-2}[/tex]
As p=0.5, so
[tex]P(r=2)=\binom {3}{ 2} (0.5)^2(1-0.5)^{3-2} \\\\=\binom {3}{2} (0.5)^2(0.5)^{1} \\\\=3\times 0.5^3[/tex]
=0.375
Hence, the probability of exactly 2 boys in a total of 3 birth is 0.375.

A bunny seller began their business with only 2 bunnies. The seller noticed that the number of bunnies the farm expanding after t days can be modeled by the equation P = 2 ∙ 3^t In this equation, what does 3^3 represent? *
Step-by-step explanation:
A bunny seller began their business with only 2 bunnies. The seller noticed that the number of bunnies the farm expanding after t days can be modeled by the equation
[tex]P=2(3)^t[/tex]
we know that the exponential equation is in the form of
[tex]y=a(b)^x[/tex]
Where 'a' is the initial value
y is the final value
b is the rate factor
x is the time period
P=2(3)^t
[tex]3^3[/tex] represent the value of t is 3
we know that 't' represents the number of days
[tex]3^3[/tex] represent the farm expanding after 3 days
Stephen and Bridget win some money and share it in the ratio 1:3. Stephen gets £11. How
much did they win in total?
Answer:
£44
Step-by-step explanation:
We have been given the ratio 1 : 3 , where 1 is stephens value and 3 is bridgets value.
We have told that stephen gets £11.
The relationship between stephens 'value' of 1 and the amount of money that he actually gets (11) is x11.
Therefore we must also x11 to Bridgets value.
11 x 3 = £33
Now, we add the two answers to find how much they won in total.
£33 + £11 = £44

7. In the right triangle below, find the length of the third side.
B
15
10
C
Answer:
If you need to find the hypotenuse, then square the two sides and add them together then square root that answer to get the hypotenuse. If you need to find a side then take the hypotenuse and other side and square them then subtract the side by the hypotenuse and then square root that answer.
Step-by-step explanation:
legs; a b hypotenuse c
a^2 + b^2 = c^2 then square root this answer
c^2 - b^2 = a^2 then square root this answer
c^2 - a^2 = b^2 then square root this answer

do you want to make a sodium carbonate solution with a concentration of 2.5%. You have 50 mL of a 1% solution about how many milliliters of a 6% solution should you add
9514 1404 393
Answer:
21 3/7 mL ≈ 21.43 mL
Step-by-step explanation:
Let x represent the amount of 6% solution that should be added. The the total volume of sodium carbonate in the mix is ...
1%(50) +6%(x) = 2.5%(50 +x)
50 +6x = 125 +2.5x . . . . . multiply by 100, eliminate parentheses
3.5x = 75 . . . . . . . . . . . . . subtract 2.5x+50
x = 21 3/7 . . . . . . . . . . . . . divide by 3.5
21 3/7 mL, about 21.43 mL, of 6% solution should be added to make a 2.5% solution.

blank + blank = internal energy
Answer:
kinectic + electric = internal
Step-by-step explanation:
Internal energy U of a system or a body with well defined boundaries is the total of the kinetic energy due to the motion of molecules and the potential energy associated with the vibrational motion and electric energy of atoms within molecules. Internal energy also includes the energy in all the chemical bonds.
Answer:
The internal energy of a system is identified with the random, disordered motion of molecules; the total (internal) energy in a system includes potential and kinetic energy. This is contrast to external energy which is a function of the sample with respect to the outside environment (e.g. kinetic energy if the sample is moving or potential energy if the sample is at a height from the ground etc). The symbol for Internal Energy Change is ΔU .
Energy on a smaller scale
Internal energy includes energy on a microscopic scale
It is the sum of all the microscopic energies such as:
translational kinetic energy
vibrational and rotational kinetic energy
potential energy from intermolecular forces
One gram of water at zero °Celsius compared with one gram of copper at zero °Celsius do NOT have the same internal energy because even though their kinetic energies are equal, water has a much higher potential energy causing its internal energy to be much greater than the copper's internal energy.

Alex and Sophia share £20 in the ratio of 2:3. Work out how much money each person gets.
Answer:
Alex will get 8 pounds and Sophia will get 12 pounds
Step-by-step explanation:
Since the ratio is 2:3, the total ratio is 5 (2+3)
divide 20 pounds from 5
and each unit will have 4 pounds
Therefore, Alex will get 8 pounds and Sophia will get 12 pounds
How many points does the team have?
How many games has this team lost?
Step-by-step explanation:
P = 3W + D
When W = 5 and D = 3, P = 3(5) + 3 = 18.
When P = 50 and D = 14,
(50) = 3W + (14), 3W = 36, W = 12.
Since the team has 12 wins and 14 draws,
they have 35 - 12 - 14 = 9 losses.
The following table shows the number of alligators in each body of water near Tom's house. Number of alligators 7,0,11,10 find the mean number of alligators.
Answer:
Mean number of alligators = 7
Step-by-step explanation:
Given that:
Number of alligators
7, 0, 11, 10
Sum of quantities = 7 + 0 + 11 + 10
Sum of quantities = 28
Number of quantities = 4
We can find the average by dividing the sum of quantities by number of quantities.
Mean = [tex]\frac{28}{4}[/tex]
Mean = 7
Hence,
Mean number of alligators = 7
Answer:
7
Step-by-step explanation:
So there were four different places and four different amounts of alligators.
The numbers are 7, 0, 11, 10.
When you add 7, 0, 11, 10, you get the number, you get 28.
You then divide 28 by 4, because there are four different numebrs on the chart. 7(1), 0(2), 11(3), 10(4).
After you divide this, the mean would be 7 because 28/4 = 7. (28/4 means 28 divided by 7)
