What is 20.8 rounded to the nearest hundredth

Answers

Answer 1

Answer:
The next bigger hundredth is 20.81 .
The next smaller hundredth is 20.79 .
Neither of those is closer to 20.8 than 20.8 already is.
So 20.8 is already rounded to the nearest hundredth.

Answer 2

Answer: It's already rounded to the nearest hundredth.

The amount of money in an account with continuously compounded interest is given by the formula A = Pert , where P is the principal, r is the annual interest rate, and t is the time in years. Calculate to the nearest hundredth of a year how long it takes for an amount of money to double if interest is compounded continuously at 3.1%. Round to the nearest tenth.

Answers

A=future amount
P=present amount
r=rate in decimal
t=time in years

when A=2P, then that is double
A=Pe^(rt)
2P=Pe^(rt)
divide by P
2=e^(rt)
r=3.1% or 0.031 solve for t
2=e^(0.031t)
take the ln of both sides
ln(2)=0.031t
divide both sides by 0.031
(ln(2))/0.031=t

a random sample of 130 students is chosen from a population of 4,500 students. if the mean iq in the sample is 120 with a standard deviation of 5, what is the 99% confidence interval for the students' mean iq score? answers given below: 118.87−121.13 107.12−132.88 125−135 115−125

Answers

Answer with explanation:

Total Sample Size = 4,500 Students

Sample Chosen(n) = 130 students

Mean IQ of the Sample, $\bar{X} = 120$

Standard Deviation, $\sigma=5$

To Calculate 99% confidence interval for the students' mean IQ score, we will calculate,

$Z_(99 percent)=2.58$

Formula for Confidence Interval

$=\bar{X} \pm Z_(99 percent)* (\sigma)/(√(n))\n\n=120 \pm 2.58 * (5)/(√(130))\n\n=120 \pm (12.9)/(11.401)\n\n =120 \pm 1.1314\n\n=120 \pm 1.13$

The Value of Confidence interval will lie between

⇒ 120 - 1.13 to 120 +1.13

⇒118.87 to 121.13

Option A: 118.87−121.13

$C.I.=120 \pm z_( \alpha /2) ( \sigma )/( √(n) ) \n =120 \pm 2.58 * (5)/( √(130) ) \n =120 \pm 1.13 \n =118.87 - 121.13$

Determine if the sequence is arithmetic write yes or no 5,9,14,20

Answers

Final answer:

The sequence 5, 9, 14, 20 is not arithmetic.

Explanation:

Yes, the sequence 5, 9, 14, 20 is an arithmetic sequence.

To determine if a sequence is arithmetic, we need to check if the difference between consecutive terms is constant.

In this sequence, the difference between consecutive terms is:

9 - 5 = 4

14 - 9 = 5

20 - 14 = 6

Since the differences are not constant, the sequence is not arithmetic. The answer is no.

Answer: No

Step-by-step explanation:

An arithmetic sequence is one where the same number is being added to the number before it. For example, 2, 4, 6, 8..., where 2 is being added to each number.

In this case, however, the number being added is not consistent with this pattern. Between 5 and 9, the difference is 4 and between 9 and 14, the difference is 5, and so forth. This pattern does not follow the rules of an arithemtic sequence.

What two numbers multiply into 30 but adds up to negative 11

Answers

-6 and -5 both add up to -11 and multiply to 30

-5*-6 = 30, since the two factors are negative the answer is positive.
-5-6 = -11, -5-6 is the same as -5 + -6 which equals -11
