I’m not sure if this is right. But I think it’s 29

x=4
8(4) -3
32-3=29

Orthogonalizing vectors. Suppose that a and b are any n-vectors. Show that we can always find a scalar γ so that (a − γb) ⊥ b, a

jeka57 [31]

Answer:

$\\ \gamma= \frac{a\cdot b}{b\cdot b}$

Step-by-step explanation:

The question to be solved is the following :

Suppose that a and b are any n-vectors. Show that we can always find a scalar γ so that (a − γb) ⊥ b, and that γ is unique if $b \neq 0$ . Recall that given two vectors a,b a⊥ b if and only if $a\cdot b =0$ where $\cdot$ is the dot product defined in $\mathbb{R}^n$ . Suposse that $b\neq 0$ . We want to find γ such that $(a-\gamma b)\cdot b=0$ . Given that the dot product can be distributed and that it is linear, the following equation is obtained

$(a-\gamma b)\cdot b = 0 = a\cdot b - (\gamma b)\cdot b= a\cdot b - \gamma b\cdot b$

Recall that $a\cdot b, b\cdot b$ are both real numbers, so by solving the value of γ, we get that

$\gamma= \frac{a\cdot b}{b\cdot b}$

By construction, this γ is unique if $b\neq 0$ , since if there was a $\gamma_2$ such that $(a-\gamma_2b)\cdot b = 0$ , then

$\gamma_2 = \frac{a\cdot b}{b\cdot b}= \gamma$

Is 24 FL. Oz smaller or greater than 3 cups

user100 [1]

Take 24/8 to find out how may cups are in 24 ounces
so 24/8 = 3 cups

So it is equal to 3 cups not smaller nor greater

Records show that the average number of job applications received per week is 5.9. Find the probability of 6 job applications re

german

Answer:

16.05% probability of 6 job applications received in a given week.

Step-by-step explanation:

When you have the mean during an interval, you should use the Poisson distribution.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

Records show that the average number of job applications received per week is 5.9.

This means that $\mu = 5.9$

Find the probability of 6 job applications received in a given week.

This is P(X = 6).

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 6) = \frac{e^{-5.9}*(5.9)^{6}}{(6)!} = 0.1605$

16.05% probability of 6 job applications received in a given week.

Answer:

$\fbox {D. 3,200.4 mm}$

Step-by-step explanation:

<u>Given</u> :

[ 1 inch = 2.54 centimeters ]

<u>Unit conversions to keep in mind</u> :

<u>1 feet = 12 inches</u>
<u>1 cm = 10 mm</u>

<u />

<u>Solving</u>

10.5 feet
10.5 x 12 inches
126 inches
126 x 2.54 cm
320.04 cm
320.04 x 10 mm
3200.4 mm
