Answer:

See Explanation;

Step-by-step explanation:

The given vectors are;

$v_1=\:\:$ and $v_2=\:\:$

a) To add or subtract two vectors, we add or subtract their corresponding components

$v_1+v_2=\:\:+\:\:$

$v_1+v_2=\:\:$

$v_1-v_2=\:\:-\:\:$

$v_1-v_2=\:\:$

$v_2-v_1=\:\:-\:\:$

$v_2-v_1=\:\:$

b) See attachment for graphs(1,6

19. A teacher tells 36 students to form 4 equal groups. Write and solve a

olchik [2.2K]

4 x = 36

Step-by-step explanation:

Because the groups have an equal number of students, we assume that each of the groups has x number of students.

Therefore since there is x number of students in each of the 4 groups, there is 4 * x number of total students in all groups combined.

Since the question already indicates that there are a total of 36 students in the class, then we can indicate that..

4x = 36

The mean gross annual incomes of certified welders are normally distributed with the mean of $20,000 and a standard deviation of

masya89 [10]

Answer:

Z=±1.65

Step-by-step explanation:

Some previous concepts

The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.

A z-test for one mean "is a hypothesis test that attempts to make a claim about the population mean(μ)".

The null hypothesis attempts "to show that no variation exists between variables or that a single variable is no different than its mean"

The alternative hypothesis "is the hypothesis used in hypothesis testing that is contrary to the null hypothesis"

System of hypothesis

Null hypothesis: $\mu=20000$

Alternative hypothesis: $\mu \neq 20000$

If the random variable is distributed like this: $X \sim N(\mu=20000,\sigma=2000)$

The significance level provided is $\alpha=0.1$ and the value of $\alpha/2= 0.05$ .

Since we are conducting a bilateral test, then we have two critical values. We need to find two quantiles that accumulates 0.05 of the area on the tails of the normal standard distribution. And in order to find it we can use the following excel codes:

"=NORM.INV(0.05,0,1)" , "=NORM.INV(1-0.05,0,1)"

And we got this:

$z_{\alpha/2}=-1.65$ and $z_{1-\alpha/2}=1.65$

So the correct answer for this case is:

Z=±1.65

Which of the following equations can be used to find the length of EF in the

Vinil7 [7]

The equation which can be used to find the length of EF is option A which is EF= $\sqrt{24^{2} -12^{2} }$ .

Given the length of base of right angled triangle is 12 and the hypotenuse be 24.

We are to find the length of EF and tell which equation can be used to find the length of EF.

We know that pythagoras theorem applies in a right angled triangle.

Pythagoras theorem says that in a right angled triangle the square of the hypotenuse is equal to the sum of square of base and perpendicular.

$H^{2} =B^{2} +P^{2}$
