3(x + 1) - 2x = -6 |use distributive property: a(b + c) = ab + ac

3x + 3 - 2x = -6

x + 3 = -6 |subtract 3 from both sides

x = -9

For PE Mr Jones wants to split boys and girls equally into as many mixed groups as possible. There are 168 boys and 60 girls. Ho

Bond [772]

Answer:

Step-by-step explanation:

You need the greatest common factor of 168 and 60.

168 = 2^3 * 3 * 7

60 = 2^2 * 3 * 5

For the GCF, you need common factors with the lower exponent.

Between 2^3 and 2^2, choose 2^2.

Then you have 3 as a common factor.

5 and seven are not common.

GCF = 2^2 * 3 = 12

Answer: 12

The number of accidents that occur at a busy intersection is Poisson distributed with a mean of 4.5 per week. Find the probabili

Mariana [72]

Answer:

a) 0.01111

b) 0.4679

c) 0.33747

Step-by-step explanation:

We are given the following in the question:

The number of accidents per week can be treated as a Poisson distribution.

Mean number of accidents per week = 4.5

$\lambda= 4.5$

Formula:

$P(X =k) = \displaystyle\frac{\lambda^k e^{-\lambda}}{k!}\\\\ \lambda \text{ is the mean of the distribution}$

a) No accidents occur in one week.

$P(x =0)\\\\= \displaystyle\frac{4.5^0 e^{-4.5}}{0!}= 0.01111$

b) 5 or more accidents occur in a week.

$P( x \geq 5) = 1-\displaystyle \sum P(x$

c) One accident occurs today.

The mean number of accidents per day is given by

$\lambda = \dfrac{4.5}{7} = 0.64$

$P(x =1)\\\\= \displaystyle\frac{0.64^1 e^{-0.64}}{1!}= 0.33747$
