<span>The volume of a cube is defined by the formula l^3, as stated in the problem. The length of the cube given to us is 3/5 of a foot, meaning that the value of l is 3/5. So if we plug this into the equation, we get that (3/5)^3 = (3)^3/(5)^3 = 27/125. The units will also match up to be in cubic feet, so the answer is that the volume will be 27/125 cubic feet.</span>

How many solutions can be found for the equation −4x − 11 = 2(x − 3x) + 13?
nignag [31]

Answer:

None

Step-by-step explanation:

-4x-11=2(x-3x)+13

-4x-11=2x-6x+13

-4x-11=-4x+13

-11=13

Therefore, there are no solutions for the equation as both sides will never be equal to each other.

The number of internet paid search ads is increasing as advertisers move away from traditional marketing methods. The equation y
blondinia [14]

Answer: In 2005 the amount spend on internet ads = $74.6 billions.

In 2009 spending on internet search ads will reach $102 billion .

Step-by-step explanation:

Given : The number of internet paid search ads is increasing as advertisers move away from traditional marketing methods.

The equation y=6.9x+40.1 can be used to project spending on internet search ads, in billions of dollars, x years after 2000.

To estimate spending on internet ads in 2005.

We need to put x= 5 in the above equation   [∵2005-2000=5]

y=6.9(5)+40.1

y=34.5+40.1

y=74.6

i.e. In 2005 the amount spend on internet ads = $74.6 billions.

Put y= 102 in the given equation, we get

102=6.9x+40.1

61.9=6.9x   [Subtract 40.1 from both sides]

x=\dfrac{61.9}{6.9}=\dfrac{619}{69}=8.97101449275\approx9

And 2000+9=2009 [x is the number of years after 2000]

Hence, in 2009 spending on internet search ads will reach $102 billion .

The number of adult Americans from a random sample of n adults who support a bill proposing to extend daylight savings time is a
GalinKa [24]

Answer:

Right of X = 635.5

Step-by-step explanation:

By using the normal approximation to the Binomial random variable, we usually make use of continuity correction.

According to the rule of continuity;

P(X ≤ k) becomes  P( X ≤ K + 0.5)

P(X < K) becomes P(X < K - 0.5)

P(X ≥ K) becomes P(X ≥ K - 0.5)

P(X > K) becomes P(X > K + 0.5)

P(X = K) becomes P(K - 0.5 ≤ X ≤ K + 0.5)

From the given question, Assume that we are to determine the probability that more than 635 Americans support the bill.

Then we use the > sign.

∴

P(X > K ) becomes P(X > K + 0.5)

P(X > 635) becomes P(X > 635 + 0.5)

⇒ P(X > 635.5) tot the right.

Right of X = 635.5
