Step-by-step explanation:
There are 15 marbles in a jar: 4 red, 5 green, and 6 yellow. You select one marble and do not replace it. Then, you select another marble. Determine if these events are independent
The events of picking marbles from the jar is independent
An event is independent if the occurrence of one event does not depend on another event.
For example, if you toss a coin and it lands on its head. You then flip another coin and it lands on its tail. These two events are independent. The face the second coin lands on do not depend on which face the first coin lands on. Also, the face that the first coin lands on does not depend on which face the second coin lands on.
In this question, after the first marble is picked, you do not return the first marble into the jar. Then you pick a second marble. The colour of the second marble does not depend on the colour of the first marble you picked. This means that the events are independent.

David says that the numbers 2 and 4 are both composite numbers. Sarah says that 2 is a prime number and 4 is a composite number. Which statement explains who is correct?
Answer: Sarah is correct
Step-by-step explanation:
A composite number is referred to as a positive integer which is gotten when someone multiplies two positive integers that are smaller than the number. We should note that we should not use one while multiplying.
A prime number is a number that can only be divided when the number is being divided by one and itself. Examples are 2, 3, 7, 11 etc.
Based on the above analysis, 2 is a prime number while 4 is a composite number. Therefore, Sarah is correct.
What is the measure of
Given h(x)=4x+4h(x)=4x+4, solve for xx when h(x)=0h(x)=0
Answer:
The value of x is -1 when h(x) = 0
Step-by-step explanation:
Given function is:
[tex]h(x) = 4x+4[/tex]
The function is a linear function with one input.
We have to solve for x when h(x) = 0 this means that we have to put h(x) = 0 and find the value of x.
So,
[tex]h(x) = 0\\4x+4 = 0[/tex]
Subtracting 4 from both sides
[tex]4x+4-4 = 0-4\\4x = -4[/tex]
Dividing both sides by 4
[tex]\\\frac{4x}{4} = \frac{-4}{4}\\x = -1[/tex]
Hence,
The value of x is -1 when h(x) = 0
Part A Tim wants to buy three pairs of jeans. He compares the prices at a store in his neighborhood and at an online store. He finds that a pair of jeans costs $24 at the local store. If he buys online, each pair would cost $22, and he would have to pay a shipping fee of $6 per order.
Answer:
The pants from the local store would be $72.00
the pants from the online store would be $85.00
the difference in price is $13.00
therefore the pants from the local store would be cheaper

Help!!!!!!!!!!!!!!!!!!!!!!!!
=======================================================
Explanation:
Look through the table to see when f(x) = g(x)
This happens when both are equal to 1, which is in the fourth row, or when x = -1.
In other words,
f(-1) = 1g(-1) = 1So f(-1) = g(-1)
We can then say the solution to f(x) = g(x) is x = -1.

2. The ratio of the length of a rectangle of its width is 6:5. Its length is 24 inches. What is its width?
Answer:
The width of the rectangle is 20 inches.
Step-by-step explanation:
Since the ratio of length to width is 6:5, the width will be 5/6 of the length. To find 5/6 of 24, multiply 24/1 by 5/6 and simplify. (24/1 is the fraction form of 24 and makes solving the problem a little easier.)
— 24/1 * 5/6 = 120/6
— 120/6 = 20
The width of the rectangle is 20 inches.
A plane can travel 5000 kilometers
in 6 hours. How far can it travel in
1.5 hours?
Answer:
1250 Kilometers.
Step-by-step explanation:
Start by finding the proper ratio of 5000:6. Now divide 6/1.5 to see what we need to divide 5000 by. 6/1.5 is 4. So divide 5000 by 4. This gives you an answer of 1250 kilometers.
Answer:
[tex]1250km[/tex]
Step-by-step explanation:
To find how far the plane can travel in [tex]1.5[/tex] hours, we need to first find the speed of the plane.
It is given that the plane can travel [tex]5000[/tex] kilometers in 6 hours, so the following equation can be written:
[tex]s = 5000km/6hours[/tex] ([tex]s[/tex] refers to the speed of the plane)
[tex]= 833\frac{1}{3}km/hour[/tex]
To find how far the plane travels in [tex]1.5[/tex] hours, we can multiply the distance it travels in 1 hour to [tex]1.5[/tex] hours:
Distance travelled [tex]= 833\frac{1}{3}\times 1.5[/tex]
[tex]=1250km[/tex]

Suppose the field is drawn on a coordinate plane, where the x- and y-values represent the position, in yards, from the center of the field, which is located at (0, 0). The location of the cones are as follows.
Cone W is located at (-38, -53).
Cone X is located at (-38, 53).
Cone Y is located at (38, 53).
Cone Z is located at (38, -53).

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 3x + 10 y is less than negative 3 over 4 times x minus 1 Part A: Clearly describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points) Part B: Is the point (8, 10) a solution to this system? Explain how you know
Answer:
See attached graph, and answers.
Step-by-step explanation:
The inequalities are given as;
i) y>3x+10
ii) y<-3/4x -1
Graphing the inequalities gives the following result
The solution area is that which is shaded and the lines are broken lines not complete
From the graph the solution is: { -2.9,1.2}
The point {8,10} is not a solution to the system. This is because it is not in the shaded area that represent the solution to the inequalities.

Jessie went to the mall and bought a CD for $12.98, a skirt for $17.50, a T-shirt for $8.50, and a bottle of water for $1.02. Use mental math to find the total amount she spent.
Answer:
$40
Step-by-step explanation:
The use of the word "mental math" means round to the nearest whole. By doing this you turn $12.98 into $13 and $1.02 into $1 which will give you $40 in total. This problem doesn't need to round as it is a simple problem. The true answer is $12.98 + $17.50 + $8.50 +$1.02= $40.

Answer:
x = -2, y = -4
x = -1, y = -1
x = 0, y = 2
x = 1, y = 5
Step-by-step explanation:
Just apply the formula into the different values for x.
x = -2
y = 3(-2) + 2
= -6 + 2
= -4
x = -1
y = 3(-1) + 2
= -3 + 2
= -1
x = 0
y = 3(0) + 2
= 0 + 2
= 2
x = 1
y = 3(1) + 2
= 3 + 2
= 5
