Answer:

Step-by-step explanation:

18.4 + 8w = 6(-4.6 + 9w)

18.4 + 8w = (-4.6 * 6 + 9w * 6)

18.4 + 8w = (-27.6 + 54w)

18.4 + 8w + -54w = -27.6 + 54w + -54w

18.4 + -46w = -27.6 + 54w + -54w

18.4 + -18.4 + -46w = -27.6 + -18.4

Combine like terms: 18.4 + -18.4 = 0.0

0.0 + -46w = -27.6 + -18.4

-46w = -27.6 + -18.4

-27.6 + -18.4 = -46

-46w = -46

w = 1

Answer:

W = 1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

18.4+8w=6(9w−4.6)

18.4+8w=(6)(9w)+(6)(−4.6)(Distribute)

18.4+8w=54w+−27.6

8w+18.4=54w−27.6

Step 2: Subtract 54w from both sides.

8w+18.4−54w=54w−27.6−54w −46w+18.4=−27.6

Step 3: Subtract 18.4 from both sides.

−46w+18.4−18.4=−27.6−18.4 −46w=−46

Step 4: Divide both sides by -46.

−46w −46 = −46 −46

w=1

Answer:

w=1

AURORKA [14]

The change of population per year is 1,900

We'll start by subtracting; 41,600-24,500= 17,100
Then we'll divide 17,100 by 9 because there is a 9 year difference between 2003 and 2012.

Select a setting so that each given point will lie within the viewing window.

NemiM [27]

Answer:

The given points are

$(-13,3)\\(0,0)\\(-2,-7)$

The setting would have a interval or 2 units above and below the minimum and maximum of each coordinate.

The given maxium horizontal coordinate is 0.

The given minimum horizontal coordinate is -13.

The given maximum vertical coordinate is 3.

The given minimum vertical coordinate is -7.

Now, we extend each maximum and minimum value by 2 units to create the setting.

So, the setting is

$x_{min}=-15\\x_{max}=2\\ y_{min}=-9\\y_{max}=5$

With a scale of 2 units.

Because all airline passengers do not show up for their reserved seat, an airline sells 125 tickets for a ﬂight that holds only

bekas [8.4K]

Answer: a) 0.9961, b) 0.9886

Step-by-step explanation:

Since we have given that

Probability that does not show up = 0.10

Probability that show up = 0.90

Here, we use "Binomial distribution":

n = 125 and p = 0.90

Number of passengers that hold in a flight = 120

a) What is the probability that every passenger who shows up can take the ﬂight?

$P(X\leq 120)=\sum_{x=0}^{120}^{125}C_x(0.90)^x(0.10)^{125-x}=0.9961$

(b) What is the probability that the ﬂight departs with empty seats?

$P(X\leq 119)=\sum _{x=0}^{119}^{125}C_x(0.90)^x)(0.10)^{125-x}=0.9886$

Hence, a) 0.9961, b) 0.9886

Answer:

The total earning of commission on sales of 85, 000 will be:

$3500+1050=4550$

Step-by-step explanation:

Total sales earning = 85,000

As salesperson earns 5% commission the first 70,000.

$\frac{5}{100}\:\times \:70\:000=3500$

As the salesperson earns 7% commission on the sales over 70,000.

As 15000 is the sales earning on which he will get commission 7%.

Because

85,000 - 70,000 = 15000

So the 7% earning of salesperson will on 15000 will be:

$\:\frac{7}{100}\:\times \:15\:000=1050$

Therefore, the total earning of commission on sales of 85, 000 will be:

$3500+1050=4550$
