Extraemos los datos del problema:

Capital Inicial Bimestre → C = S/.25000

Tasa de interés bimestral:

I = C×i

I = S/.25000 × 0.08

I = S/.2000

Monto final:

M = C + I

M = S/.25000 + S/.2000

M = S/.27000

Variación Porcentual:

% = (M - C₀) / C₀

% = ( 27000 - 25000) /  25000

% = 8

Capital Inicial Bimestre → C = S/.27000

Tasa de interés bimestral:

I = C×i

I = S/.27000 × 0.08

I = S/.2160

Monto final:

M = C + I

M = S/.27000 + S/.2160

M = S/.29160

Variación Porcentual:

% = (M - C₀) / C₀

% = ( 29160 - 25000) /  25000

% = 16.64

Capital Inicial Bimestre → C = S/.29160

Tasa de interés bimestral:

I = C×i

I = S/.29160 × 0.08

I = S/.2332.8

Monto final:

M = C + I

M = S/.29160 + S/.2332.8

M = S/ 31492.8

Variación Porcentual:

% = (M - C₀) / C₀

% = ( 31492.8 - 25000) /  25000

% = 25.97

Answer: Look

Step-by-step explanation:

Answer: We will use the SAS (SIDE-ANGLE-SIDE) to prove that the two triangles are congruent.  This states that if two sides and the included angle in one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

First line

First column: AB is congruent to CB      Second column: Given

Second line

First column: angle ABD is congruent to angle CBD      Second column: Given

At this point we have the  SIDE-ANGLE portion of SAS.  We just need the other side.  We can see from the given angles that they both share a side...BD.

Third Line

First column: BD is congruent to BD     Second column: Reflexive property

All that is left is to state SAS.

Fourth Line

First Column:  Triangle ABD is congruent to triangle CBD     Second column: SAS (from lines 1,2,3)

Answer:

7610 m

Step-by-step explanation:

600m = 600m

7km = 7000m

1000cm = 10m

The required distance = 600 + 7000 + 10 = 7610 m

Answer:

x = 7

Step-by-step explanation:

As in right triangle, the other two angles sum up equal to 90 degree, so 6x + 15 + 33 = 90, then solve for x, 6x = 90 - 15 - 33 = 42, then x = 7.

Answer:

[tex]P(A) = 0.50[/tex]

[tex]P(B') = 0.55[/tex]

[tex]P(A' U B') = 0.775[/tex]

[tex]P(A'B') = 0.275[/tex]

Step-by-step explanation:

Given

[tex]P(A\bar B) = 40\%[/tex] --- From outlet 1 alone

[tex]P(\bar A B) = 35\%[/tex] --- From outlet 2 alone

[tex]P(AB) = 10\%[/tex]  --- From both

Solving (a): Buys from outlet 1;

This is represented as: P(A)  and the solution is:

[tex]P(A) = P(A\bar B) + P(A B)[/tex]

[tex]P(A) = 40\% + 10\%[/tex]

[tex]P(A) = 50\%[/tex]

[tex]P(A) = 0.50[/tex]

Solving (b): Does not buy from outlet 2;

This is represented as: P(B') :

First, calculate the probability that the customer buys from 2

[tex]P(B) = P(\bar AB) + P(A B)[/tex]

[tex]P(B) = 35\% + 10\%[/tex]

[tex]P(B) = 45\%[/tex]

[tex]P(B) = 0.45[/tex]

Using the complement rule, we have:

[tex]P(B') = 1 - P(B)[/tex]

[tex]P(B') = 1 - 0.45[/tex]

[tex]P(B') = 0.55[/tex]

Solving (c): Does not buy from 1 or does not buy from 2

This is represented as: [tex]P(A' U B')[/tex]

And the solution is:

[tex]P(A' U B') = P(A') + P(B') - P(A'B')[/tex]

[tex]P(A' U B') = P(A') + P(B') - P(A') * P(B')[/tex]

Using complement rule:

[tex]P(A') = 1 - P(A)[/tex]

[tex]P(A') = 1 - 0.50[/tex]

[tex]P(A') = 0.50[/tex]

The equation becomes:

[tex]P(A' U B') = 0.50 + 0.55 - 0.50 * 0.55[/tex]

[tex]P(A' U B') = 0.775[/tex]

Solving (d): Does not buy from 1 or does not buy from 2

This is represented as:

[tex]P(A'B')[/tex]

And it is calculated as:

[tex]P(A'B') = P(A') * P(B)'[/tex]

[tex]P(A'B') = 0.50 * 0.55[/tex]

[tex]P(A'B') = 0.275[/tex]

Answer:

The school will approximately raise 1500p.

Step-by-step explanation:

For part a) you're asked to complete the possibility space, this simply means to fill out in the provided chart with all possible outcomes for spinning the two spinners and adding the result of each.

You are already given two examples, particularly the case of landing a 2 and 1 (hence you get a 3) and landing a 8 and 3 (hence you get an 11). Just finish filling up the chart per the examples.

For part b) we must calculate the probability of having the outcome be 7. Assuming all sides of both spinners have the same probability of landing, we calculate this using classical probability so, as follows:

[tex]P(7)=\frac{n(7)}{n(all)}[/tex]

Where [tex]P(7)[/tex] represents the probability of getting seven, [tex]n(7)[/tex] the number of ways the two spinners can land in which they add up to 7, and [tex]n(all)[/tex] the number of all possible outcomes from spinning the two spinners. We are just doing the rule of "all favorable outcomes over all outcomes".

The total number of outcomes is 12, as there's only 12 ways the two spinners could land. The total number of ways we can get 7 is 3 (only by spinning 1 and 6, or 2 and 5, or 3 and 4). So, the probability of landing 7 is:

[tex]P(7)=\frac{n(7)}{n(all)}=\frac{3}{12}=\frac{1}{4}=.25[/tex]

So, there's a 25% chance of getting a 7 (hence of winning at this game). This means, if 120 play, approximately a 25% of them will win - so, approximately 30 contestants will win.

The school is charging 20p for playing, so the 120 participants are paying 2400p. However, because approximately 30 people will win, the school will have to buy 30 lollipops that cost 30p each - so, at the end the school will raise approximately 2400p (total earnings of tickets) - 900p (total losses from people winning) = 1500p (total money raised).

21k+9k+13, and simplified into 43k.

Step-by-step explanation:

The distributive property means that you can put addends or factors in any order to get the same result(9+1=10, 1+9=10)

21k+13k+9k can be re-written into 21k+9k+13, and simplified into 43k.
