Answer:

6x-6

Step-by-step explanation:

5x-(6-x)

First you distribute the negative to (6-x) which makes -6+x, then you just subtract that from 5x which makes 5x-6+x then you just simplify into 6x-6.

Reduce then multiply. <br><br> 7/9 x 3/4 = ?<br><br> Example :

ziro4ka [17]

First, we are going to want to see if there are any terms we can simplify. By examining the numerators and denominators of our functions, we can see that we can remove a 3 from the denominator of the second function and the numerator of the first function. This would be represented as:

$\dfrac{7}{9} \cdot \dfrac{3}{4} = \dfrac{7}{3} \cdot \dfrac{1}{4}$

Now, we can multiply the fractions. Remember that to multiply fractions, simply multiply both the numerators over both the denominators, as shown below:

$\dfrac{a}{b} \cdot \dfrac{c}{d} = \dfrac{ac}{bd}$

By applying this information, we can solve for the product of the fractions:

$\dfrac{7}{3} \cdot \dfrac{1}{4} = \dfrac{7}{12}$

Our answer is $\boxed{\frac{7}{12}}$ .

Suppose Clay, a grocery store owner, is monitoring the rate at which customers enter his store. After watching customers enter f

Kitty [74]

Answer:

70th percentile for the amount of time between customers entering is 30.10

Step-by-step explanation:

given data

mean = 25

to find out

What is the 70th percentile for the amount of time between customers entering Clay's store

solution

we know that here mean is

mean = $\frac{1}{\lambda}$ ..................1

so here 25 = $\frac{1}{\lambda}$

and we consider time value corresponding to 70th percentile = x

so we can say

P(X < x) = 1 - $e^{- \lambda *x}$

P(X < x) = 70 %

1 - $e^{\frac{-x}{25}}$ = 70 %

1 - $e^{\frac{-x}{25} }$ = 0.70

$e^{\frac{- x}{25} }$ = 0.30

take ln both side

$\frac{-x}{25}$ = ln 0.30

$\frac{x}{25}$ = 1.203973

x = 30.10

70th percentile for the amount of time between customers entering is 30.10

a maximum speed, and airplane travels 2460 miles against the wind in 6 hours. flying with the wind, the plane can travel the sam

Dmitry [639]

I'm assuming you want to find the wind speed.

the ground speed against the wind is 410.
2460 / 6 = 410

the ground speed against the wind is 492.
2460 / 5 = 592

the difference is 82 mph, but you need to divide by 2 because speed is being added in one direction and subtracted in the other.

82 / 2 = 41

your final answer is 41 mph.
