Answer:
1/4 or 25%
Step-by-step explanation:
Each dice has six sides, meaning the numbers that are even are: 2,4, and 6, three even numbers per dice. Meaning the chance of rolling ONE dice is 50%. So if you were to get two even numbers on TWO dice, it would be 25% hope this helps.
The odds in favor of rolling two even numbers when rolling a pair of dice would be 25% or 1/4.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
Each dice has six sides, means the numbers that are even are:

jika pola barisan aritmatika adalah -18,-22,-26,-30, maka u20 + u 22 adalah
Answer:
-196
Step-by-step explanation:
Di sini, berdasarkan urutan aritmatika, kita ingin mencari nilai dari suku ke-22 ditambah suku ke-20.
Dari urutan tersebut, kita bisa membuat beberapa potongan.
Suku pertama a dari barisan tersebut adalah -18 Perbedaan persekutuan d = -22 - (- 18) = -22 + 18 = -4
Untuk menghitung suku ke-20, kita menggunakan rumus untuk suku ke-n dari sebuah barisan, di mana n = 20
U20 = a + (20-1)
d U20 = -18 + 19 (-4) = -18 - 76 = -94
U22 = a + (22-1) d
U22 = -18 + 21d U22 = -18 + 21 (-4) U22 = -18 - 84 = -102 Jadi;
U22 + U20 = -102 + (-94) = -196
In a college test, students receive 4 points for every question answered correctly and loses 7 points for every question answered incorrectly. On this particular test, Terry answered 87 questions correctly and 46 questions incorrectly. What is his score for the test?
Answer:Her score is 26
Step-by-step explanation:
To find the answer, we must deduct the total amount of points that are answered correctly
By the total amount of points that are answered incorrectly.
Because = 1 answered correctly = 4 points
= 1 answered incorrectly = deduct 7
points
So= 87 answered correctly × 4 points
= 348 points
So= 46 answered incorrectly × 7 points
=deduct 322 points
Then the answer will be= 348 - 322= 26

Consider the following data set with a mean of 12: 9, 11, 12, 16 Using the equation below or the standard deviation formula in Excel, calculate the standard deviation for this data set. Answer choices are rounded to the hundredths place. s equals square root of fraction numerator 1 over denominator n minus 1 end fraction sum from i equals 1 to n of open parentheses X subscript i minus X with bar on top close parentheses squared end root
Answer:
1.83
Step-by-step explanation:
The standard deviation of given data set rounded to the hundredth place is 2.55
Given data set is: 9, 11, 12, 16
The mean of the data set is 12.
The formula for standard deviation is written as:
[tex]\sigma = \sqrt{{\sum^\:n}_{i=1}{\dfrac{(x_i-\overline{x})^2}{n}}\\[/tex]
here n = 4 and x assumes 9, 11, 12 and 16 and mean is 12, thus putting values in the given formula,
[tex]\sigma = \sqrt{\dfrac{[(9-12)^2 + (11-12)^2 + (12-12)^2 + (16-12)^2]}{4}}\\\sigma = \sqrt{\dfrac{[3^2 + 1^2 + 4^2]}{4}}\\\sigma = \sqrt{\dfrac{26}{4}}\\\sigma = \sqrt{6.5}\\\sigma = 2.549..\\\sigma \approx 2.55[/tex]
Thus, standard deviation of given data set rounded to the hundredth place is 2.55

Nimisha wants to draw a wheel like the one shown. Each shaded part of the wheel should be one-third of each unshaded part. What should be the degree measure of the angle formed at the center by each shaded part?
Answer:
Each shade has a 22.5 degree angle from the middle
Each unshaded has a 67.5 degree angle from the middle.
Step-by-step explanation:
You can solve this by making each unshaded part equal to x and each shaded part equal 1/3x it is a circle so it has to equal 360 so you end up with:
x + 1/3x + x + 1/3x + x + 1/3x + x + 1/3x = 360
Combine Like terms:
16/3x = 360
Multiply both sides by the opposite:
(3/16) (16/3x) = (360) (3/16)
x=135/2 or x=67.5
Then you can plug 67.5 in for x:
1/3x ---> 1/3(67.5) = 22.5
Sunita bought a 10 kg box of grapes from the market. She gave 3 1/2 kg of her grapes to her friend Reena and 2 1/4 kg to Anita. How many kilograms of grapes were left with her?
Answer:
17/4 kg
Step-by-step explanation:
Sunita has = 10kg of grapes
Quantity given out :
To Reena =3 1/2
7/2 kg
To Anita =2 1/4
9/4 kg
Total quantity of grape given out
7/2+9/4
(14+9)/4
23/4
Quantity left after giving out = Total quantity of grape before giving out minus quantity of grape given out
10/1 - 23/4
40-23)/4
= 17/4 or 4 1/4
Hence, she has 17/4 kg of grape left with her

Answer & Step-by-step explanation:
Let's start with the first problem.
1.) 9a⁴b⁴ - 27a³b³
Now, we have to find a number or a term that can be divisible by both terms in the expression. 9 and 27 have a common factor of 9. a⁴b⁴ and a³b³ have a common factor of a³b³. So, let's use this information to find our answer.
The GCF of the expression is 9a³b³
Now, let's do the second problem.
2.) x² - 36
For this problem, we have to factor out the expression. Since this a perfect square binomial, we can just square the terms and that will give us our answer.
The factored form of this expression is (x + 6)(x - 6)
Lastly, let's do the third problem.
3.) x² + 7x + 10
For this problem, we are going to have to factor again. First, we can break down the middle term so we can factor the expression.
x² + 2x + 5x + 10
Now, we pair the first two terms together and the last two term together.
(x² + 2x) + (5x + 10)
Now, we factor each parentheses by finding the common factor between them.
x(x + 2) + 5(x + 2)
Since, our terms are the same in each parentheses, then that means we have factored correctly.
The factored form of this expression is (x + 5)(x + 2)
what's the correct answer to this...?
Answer:
-13

f(-2) means to replace x with -2 in the equation and solve:
3(-2) - 7 = -6 - 7 = -13

2.3 repeating as a fraction
Answer:
First, we can write:
x = 2 . ¯ 3
Next, we can multiply each side by 10 giving:
10 x = 23 . ¯ 3
Then we can subtract each side of the first equation from each side of the second equation giving:
10 x − x = 23 .¯ 3 − 2 . ¯ 3
We can now solve for x as follows:
10 x − 1 x = ( 23 + 0 . ¯ 3 ) − ( 2 + 0 . ¯ 3 ) ( 10 − 1 ) x = 23 + 0 . ¯ 3 − 2 − 0 . ¯ 3
9 x = ( 23 -2 ) + ( 0 . ¯ 3 − 0 . ¯ 3 )
9 x = 21 + 0
9 x = 21
9 x /9 = 21 /9
9 x /9 = 3 × 7 /3 × 3
x = 3 × 7 /3 × 3
x = 7 /3

Do I just set it equal to 180? or am i wrong
Answer:
AB=18 units.
Step-by-step explanation:
So, one of the angle measures is 6x. Since the shape is an equilateral triangle, this means that all the angles measure 6x. In other words, the total measure of the three angles is 6x+6x+6x=3(6x) or 18x. Recall that a triangle has a total interior angle sum of 180. Therefore, set 18x to 180 and solve for x:
[tex]18x=180\\[/tex]
Divide both sides by 18:
[tex]x=10[/tex]
Therefore, x is equal to 10.
Now, since this is an equilaterial triangle, all three side lengths are the same. Thus, AB=BC=AC. We know that BC is equal to x+8. Find BC:
[tex]BC=x+8\\BC=(10)+8\\BC=18[/tex]
And since all the side lengths are equivalent, this means that side AB is also 18 units.
Answer:
See below.
Step-by-step explanation:
The 3 angles in the triangle add up to 180 degrees
Also, as all 3 sides are equal, all 3 angles are also equal and each has the value 180/3 = 60 degrees.
So 6x = 60
x = 10.
Now AB = BC = x + 8
Therefore AB = x + 8
= 10 + 8
= 18.
