How do I solve log(2)t^3-1=-3?

Ne4ueva [31]

Assuming you mean
$log_2(t^3-1)=-3$
remember
$log_a(b)=c$ translates to $a^c=b$
translate

$log_2(t^3-1)=-3$ translates to $2^{-3}=t^3-1$
$\frac{1}{2^3} =t^3-1$
$\frac{1}{8} =t^3-1$
add 1 to both sides
$\frac{9}{8} =t^3$
cube root both sides
$\frac{ \sqrt[3]{9} }{2}=t$

Listed below are prices in dollars for one night at different hotels in a certain region. Find the range, variance, and standar

Vanyuwa [196]

Answer:

Range = $115

Variance = $1915.2857

Standard deviation = $43.764

Step-by-step explanation:

Given the data:

234 160 119 131 218 207 146 141

Arranging in ascending order :

119, 131, 141, 146, 160, 207, 218, 234

The range = maximum - minimum

The range = 234 - 119 = 115

The variance :

Σ(x - mean)²/n-1

The mean = Σx / n

The mean = 1356 / 8 = 169.5

Variance :

Σ(x - mean)² = (119-169.5)² + (131-169.5)² + (141-169.5)² + (146-169.5)² + (160-169.5)² + (207-169.5)² + (218-169.5)² + (234-169.5)² = 13407

n - 1 = 8 - 1 = 7

Variance = 13407 / 7 = 1915.2857

Standard deviation = √variance

Standard deviation = √1915.2857

Standard deviation = $43.764

Movie Ticket Sales : 6x + 9y = 1,500 Which graph shows this relationship?

sukhopar [10]

Ok so we have movie ticket sales and we have 6x+9y=1,500. So for types of graphs, we have linear, exponential, quadratic, and those are the basic types of graphs. Now looking at the equation, we can quickly see that the answer is linear because, looking at the constant, 1500 and the other numbers, we can see the graph will be increasing linear. Hope this helped, feel free to ask questions if you have any!

On monday it took 5 builders to 3 1/2 hours to build a wall

zubka84 [21]

Answer: £ 81.38

Step-by-step explanation:

Given: On Monday,

5 builders took $3\dfrac{1}{2}$ hours ( i.e. $\dfrac{7}{2}$ hours ) to build a wall.

On Tuesday, only 2 builders were available.

As workers are inversely proportional to the time if the job remains constant.

Inverse variation equation : $x_1y_1=x_2y_2$

Let x be the time taken by 2 builders, then

$2\times x =5\times \dfrac{7}{2}$

$\Rightarrow\ x=\dfrac{35}{2}\times\dfrac{1}{2}=\dfrac{35}{4}=8.75$

So, 2 builders will take 8.75 hours.

Each paid £9.30 for each hour.

Then, each builder will be paid for the work completed on Tuesday = £9.30 x 8.75

≈ £ 81.38

Hence, each builder will be paid £ 81.38 for the work completed on Tuesday .
