Answer and Step-by-step explanation:

Both of these questions equal the same thing.

For example, typically in a normal math situation, a number like this: 4.5 would be bigger than the number 4.10.

When looking at a decimal, first you should look at the ones place, which (going back to the real problem) would be the 11 in both questions. But, both of the whole numbers are the same, so this doesn't work.

Instead, we will look at the tenths placement, which would be the 3 behind the decimal. Still, they are the same. So, we will try the hundredths placement, which is the 4 in this problem. Still, no.

Now we check the thousandths placement. In 11.340, we have a zero, but in 11.34, it appears that we don't have one. But, anytime that you don't see a number after a certain point in the decimal (like the 11.34 in this problem) there is an invisible zero there that you can add if necessary.

So, 11.34 is equal to 11.340.

11.340 = 11.340.

I hope that this helps.

A set of 6 number cards contain the numbers 2, 5, 7, 8, 9, and 11. Which ratio is less than the ratio of odd number cards to tot

Tamiku [17]

Answer:

$Ratio = 2:3$

Step-by-step explanation:

Given

$Cards = \{2,5,7,8,9,11\}$

Required

Ratio of odd numbers to total

First, list out the odd numbers

$Odd = \{5,7,9,11\}$

The card has 4 odd numbers out of a total of 6.

So, the ratio is:

$Ratio = Odd : Total$

$Ratio = 4:6$

Divide by 2

$Ratio = 2:3$

Hence, the ratio of odd to total is 2 to 3

What is the area of a sector with a central angle of 210 degrees and a diameter of 4.6m?

WINSTONCH [101]

Sector area = (central angle / 360) * PI * radius^2
sector area = (210 / 360) * PI * 2.3^2
sector area = (7 / 12) * PI * 5.29
sector area = 9.6944313302 
sector area = 9.7 square meters (rounded)

It is generally claimed that the average body temperature for healthy human adults is 98.6°F. To test this claim a simple random

Rzqust [24]

Answer:

Explained below.

Step-by-step explanation:

The information provided is as follows:

$\mu=98.6^{o}F\\\bar x=98.1^{o}F\\s=0.9^{o}F\\n=9$

(1)

A single mean test is to be performed in this case.

As the population standard deviation is not provided, a one-sample t-test will be used.

The correct option is b.

(2)

The null hypothesis is:

H₀: The average temperature in the population is 98.6°F, i.e. μ = 98.6°F.

The correct option is b.

(3)

The alternative hypothesis is:

Hₐ: The average temperature in the population is less than 98.6°F, i.e. μ < 98.6°F.

The correct option is c.

(4)

The standard deviation of the sample mean is as follows:

$SD_{\bar x}=\frac{s}{\sqrt{n}}=\frac{0.9}{\sqrt{9}}=0.3^{o}F$

Thus, the value of SD is 0.3°F.

(5)

Compute the value of test statistic as follows:

$t=\frac{\bar x-\mu}{SD_{\bar x}}$

$=\frac{98.1-98.6}{0.3}\\\\=-1.666666667\\\\\approx -1.67$

Thus, the value of test statistic is -1.67.

(6)

The degrees of freedom of the test are:

df = n - 1

= 9 - 1

= 8

Thus, the degrees of freedom of the test is 8.
