Answer:

The number of coins in the bag  =  6

The number of notes in the bag  =   16

Step-by-step explanation:

The ratio of coins to the notes  = 3: 8

Now, let us assume in the given ratio, the COMMON FACTOR  = m

So, the number of coins in the bag = 3 times (m)  = 3 m

And, , the number of notes in the bag = 8 times (m)  = 8 m

Also, total items in the bag = 22

⇒  Number of (Notes + Coins)  = 22

⇒    3 m  +  8 m = 22

or, 11  m = 22

or, m =  22/ 11  = 2

⇒   m = 2

So, the common factor in the given ratio = 2

So, the number of coins in the bag = 3 m = 3 x  2 = 6

And the number of notes in the bag  =8 x m =  8 x 2  =   16

The mean per capita income is 15,451 dollars per annum with a variance of 298,116. What is the probability that the sample mean
docker41 [41]

Answer: 0.5467

Step-by-step explanation:

Let X be the random variable that represents the income (in dollars) of a randomly selected person.

Given : \mu=15451

\sigma^2=298116\\\\\Rightarrow\ \sigma=\sqrt{298116}=546

Sample size : n=350

z-score : \dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}

To find the probability that the sample mean would differ from the true mean by less than 22 dollars, the interval will be

\mu-22,\ \mu+22\\\\=15,451 -22,\ 15,451 +22\\\\=15429,\ 15473

For x=15429

z=\dfrac{15429-15451}{\dfrac{546}{\sqrt{350}}}\approx-0.75

For x=15473

z=\dfrac{15473-15451}{\dfrac{546}{\sqrt{350}}}\approx0.75

The required probability :-

P(15429

Hence, the required probability is 0.5467.

Factor the trinomial completely.<br> 4u^4 + 4u^3 - 6u^2
Ulleksa [173]

Answer:

See below.

Step-by-step explanation:

So we have the expression:

4u^4+4u^3-6u^2

First, factor out the GCF.

The GCF is 2u². Thus:

=2u^2(2u^2+2u-3)

And this is the simplest it can get.

So we are done :)

Given: line a is parallel to line b. Identify a pair of congruent corresponding angles.
UNO [17]

Answer:

Option

D . 4 & 8

Step-by-step explanation:

we know that

When two lines are crossed by another line (which is called the transversal), the angles in matching corners are called <u><em>corresponding angles</em></u>. If the two lines are parallel, the corresponding angles are congruent.

In this problem, the two lines are parallel

therefore

m\angle 1=m\angle 5 ----> by corresponding angles

m\angle 3=m\angle 7 ----> by corresponding angles

m\angle 2=m\angle 6 ----> by corresponding angles

m\angle 4=m\angle 8 ----> by corresponding angles
