Answer:

See below

Step-by-step explanation:

7) a rectangle 12 x 8 = 96

plus semi-circle 1/2 pi r^2 = 1/2 pi 4^2 = 25.132

total = 121.132 m^2

8) Circle area = pi r^2

large circle pi * 2^2 = 4pi

MINUS the smaller one pi 1.5^2 = 2.25 pi

total = 1.75 pi = 5.498 in^2

9) Square area = 10 x 10 = 100

minus circle pi r^2 = 25pi total = 21.46 ft^2

What is the product? (3x-6) (2x^2 -7x+1)

STALIN [3.7K]

<u>Answer-</u>

$\left(3x-6\right)\left(2x^2-7x+1\right)=6x^3-33x^2+45x-6$

<u>Solution-</u>

Given the two polynomials are $3x-6, 2x^2 -7x+1$

So their product will be,

$=\left(3x-6\right)\left(2x^2-7x+1\right)$

Distributing the Parentheses,

$=3x\cdot \:2x^2+3x\left(-7x\right)+3x\cdot \:1+\left(-6\right)\cdot \:2x^2+\left(-6\right)\left(-7x\right)+\left(-6\right)\cdot \:1$

Applying minus-plus rules,

$=3\cdot \:2x^2x-3\cdot \:7xx+3\cdot \:1\cdot \:x-6\cdot \:2x^2+6\cdot \:7x-6\cdot \:1$

Simplifying further,

$=6x^3-33x^2+45x-6$

What is the rule for the given sequence? 3, 8, 23, 68, 203,

EleoNora [17]

Answer: Add the number previously added multiplied by 3;

+3x, where x is the number that was added previously

Step-by-step explanation:

3+5=8. That's the first equation, where 5 is x. Then the next equation, 8+3x=23. 8+15=23. It works for all of the equations, so that's the pattern.

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

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

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