What is an
equation of the line that passes through the points (-4, -3) and
(3, -3)?
Answer:
y=-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-3-(-3))/(3-(-4))
m=(-3+3)/(3+4)
m=0/7
m=0
y-y1=m(x-x1)
y-(-3)=0(x-(-4))
y+3=0(x+4)
y+3=0
y=0-3
y=-3

Diane has pulled 2 green marbles and 10 other marbles from a large bag. What is the experimental
probability that the next marble selected from the bag will be green?
The experimental probability that the next marble selected from the bag will be green is 1/6.
What is the experimental probability?Experimental probability is the probability that an event would happen based on a previously carried out experiment.
The experimental probability that the next marble selected from the bag will be green = total number of green marbles / total number of marbles
2 / ( 2 + 10)
= 2/12
= 1/6

Does anyone know how to solve this?
Answer:
$ 22.5
Step-by-step explanation:
B(x) = 30.50 - 0.20x
Notice that x defines the number of prints.
For prints = x = 40
B(40) = 30.50 - 0.20(40)
B(40) = 30.50 - 8
B(40) = 22.5
Remaining amount is $22.5
B(x) is defined as at starting you had $30.50 then you kept on spending with a period of 20 cents(= 0.20 dollar). So 30.50 kept on decreasing by 0.20. Each time you spend, you give 0.20.
That's why the function is 30.50 - 0.20x.
Where x is the nunber of times you spend(buying prints)

A toy remote control car is driven across a table. Based on the graph, how far from the start line will the car be after 5 seconds?
50 cm
100 cm
120 cm
160 cm
Answer:
100 cm
Step-by-step explanation:
This is a linear function with an equation of y = 20x.
Plug 5 in for x to get 100 as your answer.
Answer: 100 cm
Step-by-step explanation: Since the car can travel 20 cm per second and it traveled 80 cm in 4 sec, then it can travel 100 cm in 5 seconds
(Tip: If it asks to show your work, try drawing a ratio table and write the centimeters it travels per second .)

3x*59x=
Step-by-step explanation:
Answer:
126 degrees
Step-by-step explanation:
The opposite angles of a parallelogram are equal, so 4x + 2 = 8x - 50. By subtracting 4x from both sides of this equation, we get that 2 = 4x - 50. Adding 50 to both sides yields 52 = 4x, and dividing by 4 gives us that x = 13.
By substituting this, we see that the measure of angle A is 4(13)+2, which is 54 degrees. Angle B is supplementary to angle A, so its measure is 180-54, which is 126 degrees.

Determine the constant that should be added to the binomial so that it becomes a perfect square trinomial. Then write and factor the trinomial. x2 + 16x
Answer:
[tex]$64, \ (x+8)^2$[/tex]
Step-by-step explanation:
A perfect square trinomial is defined as an expression that is obtained from squaring a binomial equation. The perfect square trinomial is in the form of [tex]$ax^2+bx+c$[/tex].
The given expression is :
[tex]$x^2+16x$[/tex]
The co-efficient of the x-term in [tex]$x^2+16x$[/tex] is '16'.
So half of the term 16 ,
[tex]$\frac{16}{2} = 8$[/tex]
and [tex]$(8)^2=64$[/tex]
Now add 64 to the expression:
[tex]$x^2+16x+64$[/tex]
Therefore, the perfect square trinomial is
[tex]$(x+8)^2=x^2+16x+64$[/tex]

if x+2 is a factor of the polynomial: 3x²+kx, then the value is
Answer:
k = 6
Step-by-step explanation:
(x+2) is a factor of 3x²+kx so if we solve (x+2) = 0 that will give us one of the solutions of x for 3x²+kx = 0, and then we can substitute that solution in and find the value of k.
So to find a solution, (x+2) = 0 and therefore x = -2
Now substitute x = -2 into 3x²+kx = 0
so 3(-2)²+k(-2) = 0
12 - 2k = 0
2k = 12
k = 6

If the mean of A and B is 20,the mean of B and Cis 24 and the mean of A,BandC what is the mean of A and c
Answer:
The mean of A and C is equal to 10.
Step-by-step explanation:
We know that,
[tex]\text{Mean}=\dfrac{\text{Sum of observations}}{\text{Total no of obervations}}[/tex]
The mean of A and B is 20,
[tex]A+B=20\\\\A+B=40\ \ .........(1)[/tex]
The mean of B and C is 24,
[tex]B+C=24\times 2\\\\B+C=48\ \ .........(2)[/tex]
The mean of A,B and C is 18,
[tex]A+B+C=18\times 3\\\\A+B+C=54\ .....(3)[/tex]
Put the value of A+B from (1) in (3),
C = 14
Put the value of B+C from (2) in (3)
A = 6
Mean of A and C is :
[tex]M=\dfrac{A+C}{2}\\\\M=\dfrac{14+6}{2}\\\\M=10[/tex]
So, the mean of A and C is equal to 10.

Answer: 36.25°
Step-by-step explanation:
Use SOHCAHTOA (sin, cosine and tangent)
SOHCAHTOA:
SOH: Sin(θ) = Opposite / Hypotenuse
CAH: Cos(θ) = Adjacent / Hypotenuse
TOA: Tan(θ) = Opposite / Adjacent
When you have an angle that you want to solve, look at what information you're given. In this problem, we're give nthe sides that are opposite to and adjacent to the angle we want to solve. So, we use TAN.
And just as a note, θ this symbol is called theta, and it represents an angle.
TAN(θ) = Opposite / Adjacent = 11/15
Then, use the inverse of tan (you can find the button on a calculator). You can use the inverse of sine, cosine or tangent whenever you want to switch them from one side of the equation to the other.
TAN(θ) = [tex]\frac{11}{15}[/tex]
θ = [tex]tan^-1(\frac{11}{15} )[/tex]
Then, using a calculator, solve. The answer is about 36.25°

On a standardized exam, the scores are normally distributed with a mean of 350 and
a standard deviation of 40. Find the Z-score of a person who scored 346 on the exam.
Answer:
[tex]\boxed {\boxed {\sf z= -0.1}}[/tex]
Step-by-step explanation:
A z-score helps describe the relationship between a value and the mean of a group of values. Basically, it tells us how many standard deviations away from the mean a value is. The formula is:
[tex]z= \frac{x- \mu}{\sigma}[/tex]
where x is the value, μ is the mean, and σ is the standard deviation.
For this standardized exam, the mean is 350 and the standard deviation is 40. We want to find the z-score for a value of 346.
x= 346 μ= 350 σ= 40Substitute the values into the formula.
[tex]z= \frac{ 346-350}{40}[/tex]
Solve the numerator.
[tex]z- \frac{ -4}{40}[/tex]
Divide.
[tex]z= -0.1[/tex]
The z score is -0.1, so the person with a score of 346 on the exam was 0.1 standard deviations lower than the mean.
