Answer:

9 cm

Step-by-step explanation:

Find the area of the 1st triangle

A=1/2 b*h

1/2 3*3

1/2 9

4.5

Find the area of the 2nd triangle

A=1/2 b*h

1/2 3*3

1/2 9

4.5

Both triangles have an area of 4.5

To find the area of the parallelogram you have to add the area of the triangles

4.5+4.5=9

A= 9 cm

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a,b and c integers and a>1

Tamiku [17]

Answer:

Step-by-step explanation:

$5(6x+4)-2(5x-2)\qquad\text{use distributive property}\ a(b+c)=ab+ac\\\\=(5)(6x)+(5)(4)+(-2)(5x)+(-2)(-2)\\\\=30x+20-10x+4\qquad\text{combine like terms}\\\\=(30x-10x)+(20+4)\\\\=20x+24$

$20x=4\cdot5x\\\\24=4\cdot6\\\\20x+24=4(5x+6)$

Afirm’s marketing manager believes that total sales X can be modeled using a normal distribution with mean m ¼ $2.5 million and

Ugo [173]

Answer: 0.0475

Step-by-step explanation:

Given : A firm’s marketing manager believes that total sales X can be modeled using a normal distribution.

Where , Population mean : $\mu=2.5\text{ million}=2.5\times1000000=2500000$

Standard deviation : $\sigma=300000$

To find : Probability that the firm’s sales will exceed $3 million i.e. $ 3,000,000.

∵ $z=\dfrac{x-\mu}{\sigma}$

Then , for x= 3,000,000

$z=\dfrac{3000000-2500000}{300000}=1.67$

Then , the probability that the firm’s sales will exceed $3 million is given by :-

$P(z>1.67)=1-P(z$

Hence, the probability that the firm’s sales will exceed $3 million = 0.0475
