You are going down 1 (which is minus and going in the y direction) and to left 4 is is also minus in the x direction.
(-4 , -1) Using x as the criteria only A and C have a chance. A is incorrect, because goes up one unit over the x axis.
C <<<<< answer.

Hello!

First you have to find point h.

The you go from the center can count how many spaces over you go

Since you go 4 to the left the first number is -4

Then you count how many spaces you go up or down

Since you goes down once the second number is -1

So the answer is (-4, -1)

Hope this helps!

A normal distribution has a mean of 50 and standard deviation of 5. Which value produces a negative z-score?

zimovet [89]

Answer:

$x\:$ .

Step-by-step explanation:

The z-score for a normal distribution is calculated using the formula:

$Z=\frac{x-\mu}{\sigma}$ .

From the question, the distribution has a mean of 50.

$\implies \mu=50$ and the standard deviation is $\sigma=5$ .

For a z-score to be negative, then, $\frac{x-\mu}{\sigma}\:$ .

$\frac{x-50}{5}\:$ .

$x-50\:$ .

$x\:$ .

$\therefore x\:$ .

Any value less than 50 will produce a negative z-score

Is this right ? Geometry

elixir [45]

No, 12 is the wrong answer. 5 is correct

This is because since a and c are congruent that means y=52. And we already know that every triangle adds up to 180 degrees so, you add A and C and get 104 (52+52).
And 180-104=76 so, 14x+6 must =76.
14(5)=70+6=76. 76+104=180, therefore, x=5.

If ON = 8x − 8, LM = 7x + 4, NM = x − 9, and OL = 5y − 7, find the values of x and y for which LMNO must be a parallelogram.

agasfer [191]

Step-by-step explanation:

<h2>Answer:-</h2><h3>Given :-</h3>

ON = 8x − 8
LM = 7x + 4
NM = x − 9
OL = 5y − 7

We need to find the value if x and y.

Concept:-

The sides of a parallelogram, where equal and where they are not.

Working with it:-

If LMNO is a parallelogram, the sides LM is opposite ON.

$7x + 4 = 8x - 8$

$7x - 8x = - 8 - 4$

$- x = - 12$

$\boxed{x = 12}$

Now, let us find y, in same way.

$x - 9 = 5y - 7$

Now, we found the value of x as 12, we will place it.

$12 - 9 = 5y - 7$

$3 = 5y - 7$

$3 + 7 = 5y$

$10 = 5y$

$\boxed{y = \frac{10}{5} = 2}$

So value of y is 2.

If viewing in Brainly app, extend $\longrightarrow$ side.

There are 6 cards with a picture of a rose and 4 cards with a picture of a daisy. Alfa keeps all the cards face down on a table

Igoryamba

It's 5 over 9 because you start off with 10 cards (6 roses 4 daisies) then you pick a rose. Then it become's 5 over 9 since there are only 5 roses left and 9 total cards left.
