A bag with 6 marbles is shown below. (3 marbles are red, 1 is yellow, and 2 are blue.) A marble is chosen from the bag at random. What is the
probability that it is red?
Write your answer as a fraction or a whole number.
Answer:The answer is 1/2 or you can do 3/6 if it doesnt need to be simplified
Step-by-step explanation:
Probability is the chance of an event to occur from a number of possible outcomes.
The probability that a marble chosen at random is red is 1/2.
What is probability?It is the chance of an event to occur from a number of possible outcomes.
It is given by:
Probability = Number of required events / Total number of outcomes
We have,
Total number of marbles in the bag = 6
Number of red marbles = 3
Number of yellow marbles = 1
The number of blue marbles = 2
The probability that a marble chooses is red:
= Number of red marbles / total number of marbles
= 3 / 6
= 1 / 2
Thus,
The probability that a marble chosen at random is red is 1/2.

Let f(x) = 4 - x^2 and g(x) = 2 - x. Find(f - g)(x)
Answer:
-x^2 +x +2
Step-by-step explanation:
f(x) = 4 - x^2 and g(x) = 2 - x
(f - g)(x) = 4 -x^2 - (2-x)

In which of the following situations should the t distribution be used? a. When the sample standard deviation is used to estimate the population standard deviation b. Only when the population mean is 0 c. When the sample size is less than 30 d. When the population is not normally distributed
Answer:
a. When the sample standard deviation is used to estimate the population standard deviation
Step-by-step explanation:
T or Z distribution:
If we have the standard deviation for the sample, we use the t-distribution.
If we have the standard deviation for the population, we use the z-distribution.
Thus, the correct answer for this question is given by option a.

C. ΔABE≅ΔDBC by SAS
Step-by-step explanation:
Only two sides are marked as congruent. So, any claim using SSS is automatically false. (SSS requires 3 corresponding sides be congruent.)
Of the claims citing SAS, the one regarding ΔABD is false. The points A, B, and D are on the same line, so do not form a triangle.
The only correct claim is that of C: ΔABE≅ΔDBC by SAS
What is the equation of the line that passes through the points given in the table
Answer:
B: y = -2x + 5
Step-by-step explanation:
-2 - 1 = -3
9 - 3 = 6
[tex]\frac{6}{-3}[/tex] = -2
gradient = -2
3 = 1 x -2 + c
3 = -2 + c
5 = c
y intercept = 5
equation = y = -2x + 5

Which of these points is on circle with a center at (0, 0) that includes the point (-1, -3)?
¿Cuál de los siguientes puntos está en el círculo con centro en (0,0) y incluye el punto (-1.-3)?
A. (0, 10)
B. (10, 10)
C (V10,0)
D(V10,10
Answer:(0,10)
Step-by-step explanation:
The points On circle with a center at (0, 0) that includes the point (-1, -3) would be (0, 10).
What is the equation of the circle with radius r units, centered at (x,y) ?If a circle O has a radius of r units length and that it has got its center positioned at (h, k) point of the coordinate plane,
then, its equation is given as:
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
We have given On circle with a center at (0, 0) that includes the point (-1, -3).
So the equation form
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
[tex](x-0)^2 + (y-0)^2 = r^2\\\\x^{2} +y^{2} =r^{2} \\\\(-1)^{2} +(-3)^{2} =r^{2} \\\\r^{2} = 10[/tex]
So, the other point that satisfies the equation would be (0, 10).

i need the answer to
7(p + 1) = 2(3p + 1)
Answer:
p = -5
Step-by-step explanation:
7(p + 1) = 2(3p + 1)
Distribute on both sides.
7p + 7 = 6p + 2
Subtract 6p from both sides.
p + 7 = 2
Subtract 7 from both sides.
p = -5
Answer:
p = -5
Step-by-step explanation:
7(p + 1) = 2(3p + 1)
Distribute
7p +7 = 6p +2
Subtract 6p from each side
7p +7 -6p = 6p+2-6p
p+7 = 2
Subtract 7 from each side p+7-7 =2-7
p=-5

A cylindrical shoe polish tin is 10cm in diameter and 3.5cm deep
calculate the capacity of the tin in cm^3
Answer: 274.75
Step-by-step explanation:
To find the volume of a cylinder you find the area of the base and then multiply it by the height. The base is the radius (half the diameter) squared times pi which we will use 3.14. That gets us 78.5. Then we multiply by the height to get 274.75!
Hope this helps!
The capacity/volume of the cylinder is approximately: 274.89 cm³
What is the Capacity of a Cylinder?capacity of a cylinder = volume of cylinder = πr²h.
Given the following:
Radius (r) = 10/2 = 5 cmHeight (h) = 3.5 cmCapacity/Volume of the cylinder = π(5²)(3.5)
Capacity/Volume of the cylinder ≈ 274.89 cm³

Solve for the value of X. Round to the nearest whole number.
Answer:
x = 30º
Step-by-step explanation:
This answer requires trigonometry, specifically, the cosine function. This is because we are given the length of the side adjacent to x and the length of the hypotenuse.
If you recall:
[tex]cos(x )= \frac{adjacent}{hypotenuse}[/tex]
Therefore,
[tex]cos(x) = \frac{13}{35}[/tex]
Now, we must use the inverse cosine function on a calculator to figure out the value of x.
[tex]cos^{-1}(\frac{13}{15}) = 29.93[/tex]
Now, we must round it to the nearest whole number, so x = 30º.

Bob earns $60,000 a year at an accounting firm. Each year, he receives a raise. Bob has determined that the probability that he receives a 10% raise is 0.7, the probability that he earns a 3% raise is 0.2, and the probability that he earns a 2% raise is 0.1.A competing company has offered Bob a similar position for $65,000 a year. Bob wonders if he should take the new job or take his chances with his current jo
Answer:
He should keep his job.
Step-by-step explanation:
We know that there is a 70% chance that he willend up getting a 10% raise. A 10% raise will allow him to make 66000 dolllars, which is 1000 more than getting a new job.
There is a 30% chance that he will make about 3,100 dollars less than a new job. However, 30% is much lower than 70%, so this probably wont be the outcome. And over future years, if this remains constant, he will end up still making more money staying wiht his job.
