Complete the inequality statement. 8 5/12 8 3/8

Gnoma [55]

Answer:

8 5/12 > 8 3/8

Step-by-step explanation:

The integer parts of the numbers are the same, so we can find the desired result by comparing the fractions. To do that, we can subtract one from the other, or we can simply write them both with a common denominator.

Subtracting:

5/12 -3/8 = (5·8 -12·3)/(12·8) = 4/(12·8) = 1/24 > 0

so we have ...

5/12 > 3/8

8 5/12 > 8 3/8

Common Denominator:

The denominators of the fractions are 12 and 8. The least common multiple of these numbers is 12·2 = 8·3 = 24. Then the numbers can be written as ...

8 5/12 = 8 10/24

8 3/8 = 8 9/24 . . . . . . this is less than 8 10/24

Then the appropriate relation between the numbers is ...

8 5/12 > 8 3/8

Helppp please show work

Mamont248 [21]

Step-by-step explanation:

Given that:-

Side AC measures 6 units
Side BC measures 9.5 units
Side AB measures 11 units

To find:-

The cosB as a decimal rounded to the nearest hundredth

We know that, 

${ \bigstar \: { \underline{ \boxed{ \cos( \theta ) \: = \sf\frac{adjecent \: side}{hypotenuse} }}}}$

Solution:

$\longrightarrow \rm \cos(B) = \dfrac{BC}{AB}$

$\longrightarrow \rm \cos(B) = \dfrac{9.5}{11}$

$\longrightarrow \rm \cos(B) = \dfrac{95}{110}$

$\longrightarrow \rm \cos(B) = 0.8 63$

$\longrightarrow \rm \cos(B) \approx \: 0.9$

Therefore:

Cos B equals 0.9

Consider a population with 3 observations: 6, 10 and 12. You use simple random sampling without replacement to select a sample o

lozanna [386]

Answer:

$\dfrac{2}{3}$

Step-by-step explanation:

Given that:

The number of observations is:

6, 10, 12

If we are to use a simple random sampling without replacement, then we will have:

(6,10) (6,12) (10,12)

Here;

the sample size n = 2

The population size N = 3

For (6,10) ; The sample mean = $\dfrac{6+10}{2}$

= $\dfrac{16}{2}$

= 8

For (6,12) ; The sample mean = $\dfrac{6+12}{2}$

= $\dfrac{18}{2}$

= 9

For (10, 12) ; The sample mean = $\dfrac{10+12}{2}$

= $\dfrac{22}{2}$

= 11

The probability distribution of sample mean(x) is:

X 8 9 11

P(X=x) $\dfrac{1}{3}$ $\dfrac{1}{3}$ $\dfrac{1}{3}$

Thus, the probability that the sample mean is larger than 8 is:

P(X> 8) = P(X = 9) + P(X + 11)

P(X> 8) = $\dfrac{1}{3}+\dfrac{1}{3}$

P(X > 8) = $\dfrac{1+1}{3}$

P(X> 8) = $\dfrac{2}{3}$
