Answer:

Los números racionales son aquellos números que pueden ser expresados como una relación entre dos enteros. Por ejemplo, las fracciones 1/3 y –1111/8 ambas son números racionales. Todos los enteros están incluídos en los números racionales, ya que cualquier entero z puede ser escrito como la relación z /1.

Answer:

a=4b and b=1/4a

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

3a + 4b is the answer because there are no like terms to add

5a - 4b is the answer because there are no like terms to subtract.

Making it false because 3a + 4b = 3a + 4b not 5a - 4b

Answer:

0.25 = 25% probability that it will rain today and ruin your picnic

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Cloudy skies

Event B: Rain

20% of all days start with clouds in the air

This means that [tex]P(A) = 0.2[/tex]

50% of rainy days start with rain clouds in the air

50% of 10%. So

[tex]P(A \cap B) = 0.5*0.1 = 0.05[/tex]

What is the probability that it will rain today and ruin your picnic

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.05}{0.2} = 0.25[/tex]

0.25 = 25% probability that it will rain today and ruin your picnic

Answer:

Brand A

Step-by-step explanation:

Just took the quiz

The brand that should be Eliminated is Brand C.

The correct option is C.

Brand A :

Total Sold = 686

Returns = 33

so, % of returns = (33 * 100) / 686 = 4.8%

Brand B :

Total Sold = 492

Returns = 15

so, % of returns = (15 * 100) / 492 = 3.04%

Brand C :

Total Sold = 362

Returns = 29

so, % of returns = (29 * 100) / 362 = 8.01%

Brand D :-

Total Sold = 767

Returns = 32

so, % of returns = (32 * 100) / 767 = 4.17%

As we can see that, Brand C returns % is most.

Therefore, the store should eliminate Brand C.

1- the x-coordinate of the reflected point is the same as the x-coordinate of the original point

2- the y-coordinate of the reflected point has the same value but opposite sign of the y-coordinate of the original point

The value of 4/15 ÷ 2/3 is 2/5

In order to solve this, the first thing is to change the division sign to multiplication sign and this will be:

= 4/15 ÷ 2/3

= 4/15 × 3/2

= 12/30

Reduce to lowest term

12/30 = 2/5

In conclusion, the value of 4/15 ÷ 2/3 is 2/5.

Answer:

a.1633rad/min

b.1715feet/min

Step-by-step explanation:

We are given that

Diameter of wheel, d=2.1 feet

Radius of wheel, r=[tex]\frac{d}{2}=\frac{2.1}{2}[/tex]feet

Rate=260 rev/min

a. We have to find the angular speed of the wheel in rad/min

1 rev=[tex]2\pi[/tex]radian

Where [tex]\pi=3.14[/tex]

Using the value

Angular speed=[tex]260\times 2\times 3.14/min[/tex]

Angular speed,[tex]\omega=1633rad/min[/tex]

(b)

Speed=[tex]r\omega[/tex]

Using the formula

Speed of  the cyclist=[tex]\frac{2.1}{2}\times 1633[/tex]feet/min

Speed of  the cyclist=1714.65[tex]\approx 1715[/tex]feet/min

Answer:

The top 20% of the students will score at least 2.1 points above the mean.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The mean of a certain test is 14 and the standard deviation is 2.5.

This means that [tex]\mu = 14, \sigma = 2.5[/tex]

The top 20% of the students will score how many points above the mean

Their score is the 100 - 20 = 80th percentile, which is X when Z has a pvalue of 0.8. So X when Z = 0.84.

Their score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.84 = \frac{X - 14}{2.5}[/tex]

[tex]X - 14 = 0.84*2.5[/tex]

[tex]X = 16.1[/tex]

16.1 - 14 = 2.1

The top 20% of the students will score at least 2.1 points above the mean.

Answer:

y = x³ - 3x² + 4x - 12

Step-by-step explanation:

We are told that the polynomial intercept is 3 degree and has it's intercepts at 2, 2 and 3.

Now, at y - intercept, y = 0m

Thus, the polynomial is;. (x - 2)(x - 2)(x - 3) = 0.

This gives;

(x² - 4x + 4)(x - 3) = 0

This gives;

x³ - 12x + 4x - 3x² + 12x - 12 = 0

x³ - 3x² + 4x - 12 = 0
