Find a.b. IaI =3, IbI = 5 the angle between a and b is 2π/3

oksano4ka [1.4K]

Answer: $a\cdot b= -7.5$

Step-by-step explanation:

Formula : If a and b be any two vector , then the dot product of and b is given by $a\cdot b= |a||b|\cos {\theta}$ , where $\theta$ is the angle between them.

As per given , we have

IaI =3, IbI = 5 $\theta =\dfrac{2\pi}{3}$

Then, $a\cdot b= (3)(5)\cos \dfrac{2\pi}{3}$

$a\cdot b= (15)\cos ( \pi-\dfrac{\pi}{3})$

$a\cdot b= (15)(-\cos \dfrac{\pi}{3})$ (∵ cos (π-x)=-cos x)

$a\cdot b= (15)(-\dfrac{1}{2})$ [∵ $\cos \dfrac{\pi}{3}=\dfrac{1}{2}$ ]

$a\cdot b= -7.5$

Therefore , $a\cdot b= -7.5$

Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of

Effectus [21]

Answer:

Step-by-step explanation:

To find this probability, we shall be using the z-score route

Mathematically ;

z-score = (x -mean)/SD

From the question, x = 1.99, mean = 0 and SD = 1

So z = (1.99-0)/1 = 1.99

So the probability we want to calculate is;

P(z<1.99)

This value can be obtained from the standard normal distribution table.

P(z < 1.99) = 0.9767

The sketch of the region is as shown as in the attachment.

TiliK225 [7]

Answer:commen factoers is what you need 2 4 8 16 and so on

Step-by-step explanation:

To add mixed numbers, we first add the whole numbers together, and then the fractions. ...

If the denominators of the fractions are different, then first find equivalent fractions with a common denominator before adding. ...

Subtracting mixed numbers is very similar to adding them.
