3(m + n) - 5(2m - n) |use distributive property a(b +/- c) = ab +/- ac

= 3m + 3n - 10m + 5n

= (3m - 10m) + (3n + 5n)

= -7m + 8n

= 8n - 7m

HI Cindy

3(m + n) - 5(2m-n)

3m + 3n - 10m + 5n

3m - 10m +5n -3n

7m - 2n

I hope that's help:)

Michelin Tire Company wishes to set a minimum mileage guarantee on its new MX100 tire. Tests reveal the mean mileage is 67,900 w

Keith_Richards [23]

Answer:

The minimum guaranteed mileage is $x = 71489.55$

Step-by-step explanation:

From the question we are told that

The mean is $\mu = 67900$

The standard deviation is $\sigma = 2050$

Generally for the probability to be 4% the minimum guaranteed mileage is evaluated as

$P( X \ge x ) =1- P( \frac{X - \mu }{\sigma } < \frac{ x - 67900 }{ 2050} ) = 0.04$

$\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )$

$P( X \ge x ) =1- P( Z$

=> $P( X \ge x ) = P( Z$

=> $z = \frac{ x - 67900 }{ 2050}$

From the z table, the critical value corresponding to 0.96 to the left of the curve is

$z = 1.751$

$1.751 = \frac{ x - 67900 }{ 2050}$

=> $x = 71489.55$

The domain of a function refers to the interval of x values where the graph is defined. In order for the function to be at least 600, the x values must be between 0 and 20.

The answer is:

$0 \leq x \leq 20$

The probability that a certain kind of component will survive a shock test is 3/4. Find the probability that exactly 2 of the ne

Marina86 [1]

Answer:

Therefore the required probability is $=\frac{27}{128}$

Step-by-step explanation:

The probability of success is $\frac{3}{4}$

The number of trial = 4

X= the items survive out of 4

$P(x=r)=^nC_rq^{n-r}p^r$ p =the probability of success and q = the probability failure.

p= $\frac{3}{4}$ and $q=(1-\frac{3}{4})=\frac{1}{4}$

$\therefore P(X=2)=^4C_2(\frac{1}{4} )^2(\frac{3}{4} )^2$

$=\frac{4!}{2!2!} (\frac{1}{16} )(\frac{9}{16} )$

$=\frac{27}{128}$

Therefore the required probability is $=\frac{27}{128}$
