Answer:

If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.

Answer: x = 20

All this is exaple hople it help

Find the value of z Subscript alpha divided by 2 that corresponds to a confidence level of 89.48%.

Katyanochek1 [597]

Answer:

For this case we know that the confidence level is 89.48% or 0.8948 and the significance would be: $\alpha=1-0.8948 = 0.1052$ and the value of $\alpha/2 =0.0526$

Now we need to find a quantile in the normal standard distribution who accumulate 0.0526 of the area on each tail of the normal standard distribution and we got:

$z_{\alpha/2}= \pm 1.62015$

And we can use the following excel code for example:

"=NORM.INV(0.0526,0,1)"

Step-by-step explanation:

How do you Calculate the area of a missing square.

Amiraneli [1.4K]

Answer: Option D

Step-by-step explanation:

Hey there!

Here; Looking at it we can state that it is a Right angled triangle.

And must use the Pythagoras relation if the triangle is a Right angled triangle.

So, let's work on it.

Let ABC be a triangle.

Taking reference angle as C, we get;

perpendicular= 3m

Hypotenuse= 7m

Base = xm

Now;

${h}^{2} = {p}^{2} + {b}^{2}$

$or \: b = \sqrt{ {h}^{2} - {p}^{2} }$

Put all values.

$b = \sqrt{ {7}^{2} - {3}^{2} }$

Simplify to get answer.

$b = \sqrt{49 - 9}$

$b = \sqrt{40}$

Therefore, X= 6.3m.

Hope it helps...

PLZZZZ HELLPPP MEEE GET ANSWER

Answer:

See above photograph

Step-by-step explanation:

This is how your graph will look like with an x-intercept of [−5, 0] (will not see, according to the scale, but on my device, you can), and a y-intercept of [0, 50]. The way to figure out all the coordinates upon this scale is to simply create a y-x value chart. Plug in each input value [x-value] to get your output value [y-value]:

x|y

0|50

1|60

2|70

3|80

4|90

5|100

6|110

7|120

8|130

9|140

10|150

11|160

Then, you simply just draw your line based of this chart.

I am joyous to assist you anytime.
