The value of the collection originally was $1,000,000

What was the original value of the collection?

The original value of the collection is not known, hence, it is represented by X

The increase in value by $50,000 means that the value is X+$50,000

Now, when the error was discovered, it is now worth half of the value previously

The new value is (X+$50,000)*0.5

New value=(X+$50,000)*0.5

The new value at this point is $525,000

$525,000=(X+$50,000)*0.5

$525,000/0.5=X+$50,000

$1,050,000=X+$50,000

X=$1,050,000-$50,000

Joey earns $12 an hour. Blake earns $16 per hour. Joey receives a raise of $1.50 every six months, and Blake receives a raise of

tino4ka555 [31]

*12 + 1.5x = 16 + 0.50x*

That's the answer, since I'm late.

This is correct because when setting up this sentence as an equation, you need to look at the numbers and how they're used. There are independents and dependents.

indep.:

12,16

dep.:

1.50,0.50

Furthermore, there are 1 of each on both sides of the equation, match them from the equation by name and you get the answer.

According to a study conducted by the Toronto-based social media analytics firm Sysomos, of all tweets get no reaction. That is,

Svetllana [295]

Answer:

a) E(X) = 71

b) V(X) = 20.59

Sigma = 4.538

Step-by-step explanation:

The question is incomplete:

According to a 2010 study conducted by the Toronto-based social media analytics firm Sysomos, 71% of all tweets get no reaction. That is, these are tweets that are not replied to or retweeted (Sysomos website, January 5, 2015).

Suppose we randomly select 100 tweets.

a) What is the expected number of these tweets with no reaction?

b) What are the variance and standard deviation for the number of these tweets with no reaction?

This can be modeled with the binomial distribution, with sample size n=100 and p=0.71, as the probability of no reaction for each individual tweet.

The expected number of these tweets with no reaction can be calcualted as the mean of the binomial random variable with these parameters:

$E(X)=n\cdot p=100\cdot 0.71=71$

The variance for the number of these tweets with no reaction can be calculated as the variance of the binomial distribution:

$V(X)=np(1-p)=100\cdot0.71\cdot0.29=20.59$

Then, the standard deviation becomes:

$\sigma=\sqrt{V(X}=\sqrt{20.59}=4.538$

If the equation x² - kx - 36 = 0 has x = 12 as one root, what is the value of k?

sergiy2304 [10]

To solve for k, just plug in the x provided:

12^2 - k(12) - 36 = 0

144 - k(12) = 36

-k(12) = 1/4

k = -1/48

Let a=3/4 and b=1/5. If a*x=b, then what is x?

Anarel [89]

In general, any equation like $ax=b$ (assuming $a \neq 0$ ) is solved by

$x= \dfrac{b}{a}$

So, in your case, the solution is

$x = \dfrac{\frac{1}{5}}{\frac{3}{4}}$

Dividing by a fraction means to multiply by the inverse of that fraction:

$\dfrac{\frac{1}{5}}{\frac{3}{4}} = \dfrac{1}{5} \cdot \dfrac{4}{3} = \dfrac{4}{15}$

Week = w
1 hour = d

Formula

w = dm + c

The m is the gradient

The c is the d when w is 0

First let’s do m
m is basically how much the d changes from one point to another

So how much does d changes from 20 to 15.5
