Answer:
2
Step-by-step explanation:
1+1
2
This question is so hard
Any number times one equals itself, and any number multiplied by two equals itself plus itself, so 1*2=2 and 1*2=1+1. The transitive property of equality states that if x=y and y=z then x=z. Since both 1+1 and 2 are equal to 1*2, they must be equal to each other, so 1+1=2.
The answer is 2
A box contains 30 marbles, of which 8 are
black, 10 are green, and 12 are yellow. If two
marbles are drawn at random, what is the
probability that both the marbles will NOT be
green?
Answer:

Solve these multi step equations. Show your work. Justify each of your steps. 3x+4+6x=12-41+6x
Answer:
x=11
Step-by-step explanation:
Combine like terms:
3x +4 +6x =12- 41+ 6x
9x +4 =12 -41 + 6x
Subtract the numbers:
9x+ 4= 12- 41+ 6x
9x + 4= -29 +6x
Rearrange terms:
9x+4=-29+6x
9x+4=6x-29

Answer:
Carol makes 6 more points then Abby.
Step-by-step explanation:
Since Abby made 2 three pointers, that means that she made 6 points in total (2x3). And since Carol made 4 three pointers, it means that she made 12 points in total (4x3). To find how many more points Carol made then Abby, you have to subtract the amount of points that Abby made from the amount of points that Carol made. Doing this, you will see that Carol made 6 more points then Abby.

This question is based on the equation of circle. Therefore, the equation of circle is (x - 4)² + (y + 7)² = 81 describes a circle with center (4, -7) and radius 9.
What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.
here, we have,
Given:
A circle with center (4, -7) and radius 9.
We need to determined the equation describes a circle with center (4, -7) and radius 9.
According to the question,
As we know that, the equation of a circle in standard form is
⇒ (x - h)² + (y - k)² = r²
Where (h, k) are the coordinates of the center and r is the radius.
Here, it is given that, (h, k) = (4, - 7) and r = 9.
Therefore, by putting the given values.
We get,
⇒ (x - 4)² + (y - (- 7))² = 9², that is
⇒ (x - 4)² + (y + 7)² = 81 ← equation of circle
Therefore, the equation of circle is (x - 4)² + (y + 7)² = 81 describes a circle with center (4, -7) and radius 9.

10x-3y+2x written in fewer terms
Answer:
12x-3y
Step-by-step explanation:
combine like terms: the 10x and the 2x can be combined making it 12x and then you keep the -3y making it 12x-3y
Answer:
12x - 3y
Step-by-step explanation:
All you have to do for this question is combine like terms. It isn't wanting you to solve for anything, so it's pretty fast to do. Since the 2 and 10 both have x values next to them, you can combine them. They are both positive, so you can simply add them together. This gives you 12x. Because the -3 and 12 have different values next to them, you cannot combine them. So you are left with 12x - 3y. This is your answer.
I hope this makes sense and is easy to understand. Please let me know if you need any more help. Have a great day and good luck!!
The lifetime of a certain brand of battery is normally distributed with a mean value of 9 hr and a standard deviation of 0.8 hr when it is used in a particular DVD player. Suppose that two new batteries are independently selected and put into the player. The player stops functioning as soon as one of the batteries fails. (Round your answers to four decimal places.)
Required:
a. What is the probability that the player functions for at least 8 hr?
b. What is the probability that the cassette player works for at most 11 hr?
c. Find a number z* such that only 10% of all cassette players will function without battery replacement for more than z* hr.
Answer:
a. 0.8944 = 89.44% probability that the player functions for at least 8 hr
b. 0.9938 = 99.38% probability that the cassette player works for at most 11 hr
c. z* = 10.024 hr
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean value of 9 hr and a standard deviation of 0.8 hr
This means that [tex]\mu = 9, \sigma = 0.8[/tex]
a. What is the probability that the player functions for at least 8 hr?
This is 1 subtracted by the pvalue of Z when X = 8. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{8 - 9}{0.8}[/tex]
[tex]Z = -1.25[/tex]
[tex]Z = -1.25[/tex] has a pvalue of 0.1056
1 - 0.1056 = 0.8944
0.8944 = 89.44% probability that the player functions for at least 8 hr.
b. What is the probability that the cassette player works for at most 11 hr?
This is the pvalue of Z when X = 11. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{11 - 9}{0.8}[/tex]
[tex]Z = 2.5[/tex]
[tex]Z = 2.5[/tex] has a pvalue of 0.9938
0.9938 = 99.38% probability that the cassette player works for at most 11 hr.
c. Find a number z* such that only 10% of all cassette players will function without battery replacement for more than z* hr.
This is the 90th percentile, which is X when Z has a pvalue of 0.9, that is, X when Z = 1.28.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.28 = \frac{X - 9}{0.8}[/tex]
[tex]X - 9 = 1.28*0.8[/tex]
[tex]X = 10.024[/tex]
So
z* = 10.024 hr

1. Savannah has 5 dogs and she feeds each of them 6 oz of dog food every day. How many
pounds of dog food do they eat each day?
Answer:
0.375 lb
Step-by-step explanation:
For this one all you need to do is convert 6 oz to pounds and to do this
For example to convert an ounce measurement to a pound measurement, use a simple formula. Since one ounce is equal to 1/16 of a pound, the formula for the conversion is:
pounds = ounces ÷ 16
1. Take measurement
2. Divided ounces by 5
3. Round the result to desired decimal places.
And don't just put this answer because I am not very sure.
1.875 pounds of dog food can be eaten by 5 dogs per day.
Pound and ounce based problem:What information do we have?
Number of dogs = 5
Each dog eats per day = 6 oz
Total dog food eaten per day = Number of dogs × Each dog eats per day
Total dog food eaten per day = 5 × 6
Total dog food eaten per day = 30 oz
1 pound = 16 oz
So,
Total dog food eaten per day = 30oz / 16oz
Total dog food eaten per day = 1.875 pound
