Identify the type of sequence 1/10, 3/20, 5/30, 7/40...

1 answer:

4 0

Arithmetic sequence: must have a constant common difference.
3/20-1/10=(3-2)/20=1/20
5/30-3/20=(10-9)/60=1/60
Difference is not constant, so no.

Geometric sequence: must have a common ratio
30/20 / (1/10) = 15
5/30 / (3/20) = 100/90 = 10/9
ratio is not constant, so no.

The answer is (c) neither geometric nor arithmetic

Given that an adult likes soccer, what is the probability the adult is aged 18–30? 8.1% 18.1% 24.5% 44.4%

The probability that an adult likes soccer is aged between 18–30 will be 44.4%.

We have an adult who likes soccer.

We have to determine the probability the adult is aged 18–30.

<h3>What is Probability?</h3>

The formula to calculate the probability of occurrence of an event 'A' can be written as -

P(A) = $\frac{n(A)}{n(S)}$

where -

n(A) = Number of outcomes favorable to event A.

n(S) = Total number of outcomes.

According to question, we have an adult likes soccer.

The answer to this question is based on the hypothesis that the adults between 18 - 30 are highly energetic. To be more precisely - the adults in the range 18 - 24 and 24 - 30 are highly energetic and full of stamina. Above the age 30, the number of adults who like soccer will start to decrease and will hit nearly zero between the age range of 55 - 65 as the adults in this age group found it very difficult to even walk.

Mathematically -

The probability of an event A = an adult likes soccer is aged between 18–30 will be the highest value among the ones mentioned in options.

Hence, the probability that an adult likes soccer is aged between 18–30 will be 44.4%.

A chemist needs 130 milliliters of a 47% solution but has only 35% and 87% solutions available. Find how many milliliters of eac

choli [55]

Answer: Amount of 35% solution required = 100 milliliters

Amount of 87% solution required = 30 milliliters

Step-by-step explanation:

Given: Total solution required = 130 milliliters

Let x = Amount of 35% solution (in milliliters).

Then, Amount of 87% solution required = 130 - x

As per given,

Concentration = 0.35x +0.87(130-x)=0.47(130)

$0.35x +113.1-0.87x=61.1\\\\\Rightarrow\ -0.87x+0.35x=61.1-113.1\\\\\Rightarrow\ -0.52 x= -52\\\\\Rightarrow\ x=\dfrac{52}{0.52}=100$

Hence, Amount of 35% solution required = 100 milliliters

Amount of 87% solution required = 130-100 milliliters =30 milliliters

Step-by-step explanation:

A medida que nos alejamos del punto decimal, el número de ceros aumenta y el dígito se mueve hacia la derecha.

Los valores después del decimal se denominan décimas, centésimas y milésimas.

a) 1.585 =1.0 + 0.5+ 0.08+0.005

b) 1.059= 1 .0+ 0.0+ 0.05+0.009
