4/6 = 2/3
The probability of receiving a number greater than 3 and an even number is 2/3.
What is probability?The likelihood or chance that an event will occur is referred to as probability.When we are uncertain about the outcome of an event, we can discuss the probabilities of various outcomes—how likely they are. Statistics is the study of events governed by probability.P(E) = (Number of positive outcomes) / (Sample space)
Here,
When a die is rolled once, the sample space is
S = {1, 2, 3, 4, 5, 6}. The total score is 6.
The events will be E ={ 4, 5, 6, 2}
if a number greater than 3 and an even number are rolled. The expected result is 4.

Leticia is studying the stock market in her social studies class. Her teacher had each student pick a stock to track over eight days. Leticia picked a stock from a company that makes her smartphone. Leticia created the table tracking the amount of the price of the stock gain or loss each of the eight days of tracking trading. Time Tracking Stocks Gain/Loss -$2.25 -$1.50 $1.25 Day 1 Day 2 Day 3 Day 4 Day 5 Day 6 Day 7 Day 8 -$1.75 $3.75 -$2.50. After the first five days of tracking the stock how much in total did the stock gain or lose in value
To find how much di the stock gain or lose in value after 5 days, we just have to sum the values of the Gain/Loss column from the first row to the fifth one, like this:
Total gain or loss = -2.25 + (-1.5) + 1.25 + (-0.75) + 2.25 = -1
Then, the stock lose $1 in value ($-1)

4.There are 30 students in the classroom competing for classroom prizes. Only the first two students whose name is drawn will win a prize. The first student wins 5 bonus points and the second student wins 2 bonus points, both on the upcoming test. If you are one of the 30 students, what is the probability you will win the top prize and your best friend wins the second prize?
Out of 30 students, the probability of one student winning the top prize is 1/30.
Since the student who won the top prize cannot be the student who wins the second prize, then the probability of a student winning the second prize is 1/29.
So, the probability that you will win the top prize and your best friend wins the second prize is:
[tex]P=\frac{1}{30}\times\frac{1}{29}=\frac{1}{870}[/tex]Answer:
The probability that you will win the top prize and your best friend wins the second prize is 1/870.

On Saturday, a local hamburger shop sold a combined total of 316 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the
number of hamburgers sold. How many hamburgers were sold on Saturda
The number of cheeseburgers sold was three times the number of hamburgers sold then 79 hamburgers and 237 cheeseburgers were sold on Sunday.
How to find the number of hamburgers were sold on Sunday?Let h be the number of hamburgers
c be the number of cheeseburgers
A local hamburger shop sold a combined total of 316 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold.
h + c = 316
c = 3h
h + 3h = 316
simplifying the above equation, we get
⇒ 4h = 316
Dividing both sides of the equation by 4, we get
⇒ 4h / 4 = 316 / 4
⇒ h = 79
Therefore, hamburgers were sold on Saturday is 79.
The number of cheeseburgers sold was three times the number of hamburgers sold then
c = 3h
substitute the value of h in the above equation, we get
⇒ c = 237
Therefore, 79 hamburgers and 237 cheeseburgers were sold on Sunday.

use transformation of the parent graph of the m(x)=sqrt(x) to sketch the graph of p(x) = -sqrt(x)-3
First we need to look at the change of signal of the function (it changes from √x to -√x).
This change of signal means the function was reflected over the x-axis.
Then, the value of -3 was added to the function.
An addition of -3 in the function means a translation of 3 units down.
So the transformations from m(x) to p(x) are:

The linear equation that passes through (-2, 11) and (1, -4) is:
y = -5*x + 1
How to get the linear equation?The general linear equation is:
y = a*x +b
Where a is the slope and b is the y-intercept.
If the line passes through points (x₁, y₁) and (x₂, y₂) then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Here we know that the line passes through the points (-2, 11) and (1, -4), then the slope is:
a = (-4 - 11)/(1 + 2) = -15/3 = -5
y = -5*x + b

We need to write an equation relating x (leg CD) to the given data.
The image shows the right triangle ACD, with legs, in ft, given by:
[tex]\begin{gathered} AC=1600 \\ \\ CD=x \end{gathered}[/tex]Also, angle DAC is 25.4º. Since CD is the opposite leg, and AC is the adjacent leg to this angle, we have:
[tex]\begin{gathered} \tan 25.4\degree=\frac{CD}{AC} \\ \\ \tan 25.4\degree=\frac{x}{1600} \end{gathered}[/tex]Thus, option A is correct.
Also, we can multiply both sides of the above equation by 1600, to find the equivalent equation:
[tex]\begin{gathered} 1600\cdot\tan 25.4\degree=\frac{x}{1600}\cdot1600 \\ \\ 1600\cdot\tan 25.4\degree=x \\ \\ x=1600\cdot\tan 25.4\degree \end{gathered}[/tex]Thus, option C is also correct.
Notice that:
[tex]\begin{gathered} \cos 25.4\degree=\frac{AC}{AD} \\ \\ \cos 25.4\degree=\frac{1600^2^{}+x^2}{1600} \end{gathered}[/tex]Therefore, only options A and C are correct.

ZA and B are vertical angles. If m_A = (3x + 13) and mZB = (5x + 9), then find the measure of ZA.
Answer
Angle A = 19°
Explanation
Vertical angles are angles that are directly opposite each other at a point where two lines intersect or cross each other. Vertical angles are known to be equal to each other.
So, Angle A = Angle B
Angle A = 3x + 13
Angle B = 5x + 9
3x + 13 = 5x + 9
We can rewrite this as
5x + 9 = 3x + 13
5x - 3x = 13 - 9
2x = 4
Divide both sides by 2
(2x/2) = (4/2)
x = 2
Angle A = 3x + 13 = 3(2) + 13 = 6 + 13 = 19°

(Which one is correct and why)
Answer:
your answer is C
Step-by-step explanation:
by elimination B is not possible as the graph shows a cubic shape B has no cubic terms, D is not possible because the graph shows a translation on X axis and D represents a translation in Y axis, and A is not possible because when X=0 the value of Y must be -64 and A doesn't comply to that.
Answer:
C
Step-by-step explanation:
the graph has 3 zero solutions (values of x with y = 0).
therefore it has to be of 3rd degree (3 is the max. exponent of x).
that eliminates B, because it is only of 2nd degree.
when x = 0, y is a little bit below -60 but above -80.
but y is negative.
that eliminates A, because when x = 0, y = +64.
for x = -8, y has to be 0 too.
that eliminates D, because for x = -8, y = -8³ - 64 = -512 - 64 = -576
and not 0.
so, C must be correct.
for x = 0, y = -64
for x = -8, y = -8³ + 6×-8² - 24×-8 - 64 =
= -512 + 6×64 + 192 - 64 =
= -512 + 384 + 192 - 64 = 0
for x = -2, y = -2³ + 6×-2² - 24×-2 - 64 =
= -8 + 6×4 + 48 - 64 =
= -8 + 24 + 48 - 64 = 0
for x = 4, y = 4³ + 6×4² - 24×4 - 64 =
= 64 + 6×16 - 96 - 64 =
= 64 + 96 - 96 - 64 = 0
all fits.

A ∩ C (read as A intersection C) - are members that are common to both set A and set C.
A ∪ C (read as A union C) - are members that are in set A or set C or both, combining the members of all sets.
C' (read as C complement) - are members that are not in the universal set.
Since what we are about to find is A ∪ C', let's first determine the members of C'.
We get,

the length of th diagonal is 10√2
Explanation:side length = 10 inches
We need an illustration to solve the question:
Using pythagoras' theorem:
Hypotenuse² = opposite² + adjacent²
hypotenuse = diagonal
opposite = 10 in, adjacent = 10 in
diagonal² = 10² + 10²
diagonal² = 100 + 100
diagonal² = 200
diagonal = √200
diagonal = 10√2
Hence, the length of th diagonal is 10√2
28 ✕ 0 = 20 ✕ y.
If 0 is 140, the value of y is what?
Answer:
196 = y
Step-by-step explanation:
If o is 140, the value of y is what? 28 ✕ o = 20 ✕ y
28 ✕ o = 20 ✕ y
28 ✕ 140 = 20 ✕ y
3,920 = 20✕ y
right side: 20 is multiplied by y and can be written back to back:
3,920 = 20y
divide both sides by 20:
3,920/20 = 20y/20
196 = y
The value of y varies jointly with the values of x and z. When x=4 and z=9, the value of y is 360. What is the value of y when x=4 and z=9?
When z = 9 and x = 4, and y = 360. then, with x = 4 and z = 9, we obtain the value of y = 600.
According to question, given that
x = 4, z = 9 , y = 360
The value of y varies jointly with the values of x and z then
Joint variation ⇒ y = k. x. z , where k is constant. In all cases when k ≠ 0
360 = k (4) (9)
360 = 36 k
k = 360/36
k = 10
y = k. x. z
y = 10 .x . z
when x = 5 and z = 12 then
y = 10 .x . z
y = 10 (5) (12)
y = 600
Therefore, When x=4 and z=9, and the value of y is 360. then we get the value of y = 600, when x=4 and z=9 using joint variation.
Any number of issues involving rates, times, and work can be resolved rationally. Rational formulas include direct, inverse, and joint variation equations. In direct variation, the variables are directly related to one another; as one quantity rises, the other will as well.
