Answer:
Step-by-step explanation:
-5z>10 what is the answer to that
Answer:
[tex]\boxed{\sf{z < -2}}[/tex]Step-by-step explanation:
To solve for z, isolate it on one side of the equation.
-5z>10First, multiply by -1 from both sides.
⇒ (-5z)(-1)<10(-1)
Solve.
Multiply the numbers from left to right.
⇒ 10(-1)=(-10)
Rewrite the problem down.
⇒ 5z<-10
Then, you divide by 5 from both sides.
⇒ 5z/5<-10/5
Solve.
Divide the numbers from left to right.
⇒ -10/5=-2
[tex]\boxed{\sf{z < -2}}[/tex]
Therefore, the correct answer is z<-2.I hope this helps you! Let me know if my answer is wrong or not.
Answer:
z > -2
Step-by-step explanation:
Given inequality: -5z > 10
To determine the simplified inequality, we need to isolate "z". Divide -5 both sides to isolate the variable "z".
⇒ -5z > 10
⇒ -5z/-5 > 10/-5
Always remember that if you are dividing by a negative number, the inequality sign flips over.
⇒ z < -2
Thus, the simplified inequality is z < -2.

What is the difference between calculating probability with “and” vs “or”?
Answer:
The word or is used in probability to denote that you are computing the chance that either event A or event B occurred; both events do not have to occur. When you employ the word and, you're implying that both A and B must occur.
In Conclusion:
If either one or both of them occur, the condition is fulfilled, and the probabilities are added.
The condition is satisfied if and only if both of them occur, and the probabilities are increased.
Find YW, would it just be 6?

This works for triangles with a Midline having two of these properties:
The midline should be parallel to the third sideThe midline is half as long as the third sideThe third side of the triangle (the one parallel to its midline) is twice the length of its midline.

If LOVE is a square with LO = 2x + 3 and OV = 9, what is the value of x?
Answer:
3
Step-by-step explanation:
2x+3=9
You have to get rid of the 3 and the operation that is happening between the 2x and 3 is addition so you must do the opposite which is subtract .
2x+3-3=9-3
Cross out the 3's . What you do to one side do it to the other side .So subtract 3 from both sides .
2x÷2=6÷2
Now to get rid of the 2 you divide because the operation that is happening between the 2 and x is multiplication.And what u do to one side do it to the other . So
x= 3
Hope this helps and sorry if you don't under the explanation
Step-by-step explanation:
LO = 2x + 3 and OV = 9,
9=2x+3
9-3=2x
6=2x
6/2=x
x=3

How could you find the distance between the points (-2.5, 4.5) and (1.25, 4.5)?
Answer: By using the distance formula
Step-by-step explanation:
The distance formula can be used to find the distance between two coordinate points, as given here. They come in the order of (x, y) and you would plug in your values.
Need to solve for the distance?
Taking the formula, we will plug in the coordinate points given and solve.
[tex]\displaystyle d = \sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2}}[/tex]
[tex]\displaystyle d = \sqrt{(1.25--2.5)^{2} +(4.5-4.5)^{2}}[/tex]
[tex]\displaystyle d = \sqrt{(1.25+2.5)^{2} }[/tex]
[tex]\displaystyle d = \sqrt{(3.75)^{2} }[/tex]
[tex]\displaystyle d =3.75[/tex] units

A bag of marbles has 3 red and 6 green marbles. What is the probability of selecting two red with replacement?
Answer:
1/9
Step-by-step explanation:
With replacement, we use the principle of multiplication with counting.
[tex]\frac{3redballs}{9total balls} * \frac{3redballs}{9total balls} = \frac{1}{3}* \frac{1}{3} = \frac{1}{9}[/tex]
The probability of selecting two red marbles with replacement is 1/9.
What is probability?Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 means that the event is impossible and 1 means that the event is certain to occur.
If we select a marble at random from the bag, there are 3 red marbles out of 9 total marbles. After replacing the marble back in the bag, the probability of selecting another red marble is still 3/9 (assuming the first marble selected was red).
To find the probability of selecting two red marbles with replacement, we need to multiply the probabilities of each event happening.
Therefore, the probability of selecting two red marbles with replacement can be calculated as follows:
P(selecting two red marbles with replacement) = P(selecting a red marble) x P(selecting a red marble given that the first marble was red)
P(selecting two red marbles with replacement) = (3/9) x (3/9)
P(selecting two red marbles with replacement) = 1/9
Therefore, the probability of selecting two red marbles with replacement is 1/9.
