Answer:
2/4 or 1/2
Step-by-step explanation:
The solution is, 1/16 is the probability that you land on blue on your first spin and on yellow on your second spin.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
There are four (4) colors to choose from.
The number of sample space is equal to 4.
With the condition given in this item, the probability of landing on blue on the first spin is equal to 1/4.
Similarly, the probability of landing on yellow on the second spin is 1/4.
so, we get,
P = (1/4)(1/4)
P = 1/16
Answer: 1/16 is the probability that you land on blue on your first spin and on yellow on your second spin

Answer:
5. a = 4
7. x = -8
9. x = -1
11. p = 1.1
13. x = -1
15. x = -4
Step-by-step explanation:
2.9a = 11.6
2.9a/2.9 = 11.6/2.9
a = 4
-3.7x = 29.6
-3.7x/-3.7 = 29.6/-3.7
x = -8
(x-5)(-3) = 18
(x-5)(-3)/-3 = 18/-3
x-5 = -6
x-5+5 = -6+5
x = -1
3.6 = -2p+5.8
3.6-5.8 = -2p+5.8-5.8
-2.2 = -2p
-2.2/-2 = -2p/-2
1.1 = p
2x+6 = -4x
2x+6-6 = -4x-6
2x = -4x-6
2x+4x = -4x-6+4x
6x = -6
6x/6 = -6/6
x = -1
21-6x = -11-14x
21-6x-21 = -11-14x-21
-6x = -14x-32
-6x+14x = -14x-32+14x
8x = -32
8x/8 = -32/8
x = -4
Answer:
5.) a= 4
7.) x= -8
9.)x= -1
11.) p= 1.1
13.) x= -1
15.) x= -4
Step-by-step explanation:
5.) divide 11.6 by 2.9a
7.)divide 29.6 by -3.7u
9.) Divide by sides by -3. simplify. Add 5 to both sides. then simplify again x= -1
11.) subtract 5.8 from 3.6 . you're left with -2p=-2.2 divide both sides by -2. you get p=1.1
13.)Subtract 6 from both sides. You get 2x= -4x-6. Add 4x to both sides. then divide -6 by 6 you get x=-1
15.) Simplify both sides of the equation, so add 14x to -6x +21 side, you get 8x= -32 then divide -32 by 8x you get -4

A pile of cards contains red and blue
cards. The ratio of blue cards to red
cards is 5:7, and there are 15 blue
cards in the pile. What is the total
number of cards in the pile?
Answer:
There are 36 cards
Step-by-step explanation:
let blue be B and red be R
B:R =5:7
B/R = 5/7
there are 15 blue cards...
15/R = 5/7
make R subject of the formula...
R = (15×7)/5
R = 21
there are 21 red cards and 15 blue cards
Total number of cards = red cards + blue cards
= 21 + 15
= 36 cards
Suppose a normal distribution has a mean of 48 and a standard deviation of 5. What is the probability that a data value is between 48 and 52? Round your answer to the nearest tenth of a percent. O A. 26.2% . B. 30.5% O c. 31.1% O D. 28.8%
Answer:
31.1 best answer
sorry if it's wrong
28.8% is the probability that a data value is between 48 and 52.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
First, we need to standardize the values and use a standard normal distribution table or calculator.
The standardized value of 48 is:
z = (48 - 48) / 5 = 0
The standardized value of 52 is:
z = (52 - 48) / 5 = 0.8
Now we need to find the probability that a data value is between z = 0 and z = 0.8 in a standard normal distribution. We can use a standard normal distribution table or calculator to find this probability.
Using the table or calculator, we can find that the probability of a data value being between z = 0 and z = 0.8 in a standard normal distribution is approximately 0.2881.
Rounding this answer to the nearest tenth of a percent, we get:
P(48 < x < 52) ≈ 28.8%
Therefore, the answer is D, 28.8%.

Given the point (x, y) = (3, 8), find x' of the image point with respect to an axis rotated 60.
3/2 + 4√3
(3√3)/2 - 4
(3√3)/2 + 4
The value of x', the image point with respect to an axis rotated 60 is 3/2 + 4√3
How to determine the x' coordinate?The point is given as:
(x, y) = (3, 8)
The angle of rotation is given as:
θ = 60
The image of rotation is calculated using:
x = x'cosθ - y'sinθ
y = x'sinθ + y'cosθ
So, we have:
3 = x'cos(60) - y'sin(60)
8 = x'sin(60) + y'cos(60)
Evaluate cos(60) and sin(60)
3 = 1/2x' - y'√3/2
8 = x'√3/2 + 1/2y'
Multiply the second equation by √3
8√3 = 3/2x' + √3/2y'
Add this equation and the first equation to eliminate y'
3 + 8√3 = 1/2x' + 3/2x'
Evaluate the sum
3 + 8√3 = 2x'
Divide through by 2
x' = 3/2 + 4√3
Hence, the value of x' is 3/2 + 4√3

In a rectangle, the length is 5 more than three times the width. The perimeter is 250cm. Determine the length of each side.
Answer:
l = 95 cm
w = 30 cm
Step-by-step explanation:
w = width
5+3w = length
P = 2l + 2w
250 = 2(5+3w) + 2w
250 = 10 + 6w + 2w
240 = 8w
w = 30
5 + 3(30) = length
l = 95

A new test is developed to test for organic matter in soil samples, giving "positive" or "negative" results to indicate that a sample does or does not contain organic matter.
For a soil sample that contains organic matter, the test will give a positive result 95% of the time and a negative result (false negative) 5% of the time. For a soil sample that does not contain organic matter, the test will give a positive result (false positive) 20% of the time and a negative result 80% of the time.
A study included a population of 1,000 soil samples, and 70% of those studied where known to contain organic matter.
Fill in the missing values in the table and statement below. If necessary, round the percentage to one decimal place.

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.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
Positive results= 95%
Negative results= 5%
Now,
Positive result = 700 * 0.95 = 665
Negative result = 700 * 0.05 = 35
Similarly, for the soil samples that do not contain organic matter, we know that 20% of them will give a positive result and 80% will give a negative result. So, we can multiply 300 by 0.2 and 0.8 to get:
Positive result = 300 * 0.2 = 60
Negative result = 300 * 0.8 = 240
To fill in the missing value in the statement, we can use Bayes' theorem, which states that:
P(A|B) = P(B|A) * P(A) / P(B)
So, we have:
P(contains organic matter | positive result) = P(positive result | contains organic matter) * P(contains organic matter) / P(positive result)
P(positive result) = P(positive result | contains organic matter) * P(contains organic matter) + P(positive result | does not contain organic matter) * P(does not contain organic matter)
P(positive result) = 0.95 * 0.7 + 0.2 * 0.3
P(positive result) = 0.665 + 0.06
P(positive result) = 0.725
Plugging these values into Bayes' theorem, we get:
P(contains organic matter | positive result) = (0.95 * 0.7) / (0.725)
P(contains organic matter | positive result) = (0.665) / (0.725)
P(contains organic matter | positive result) = 0.9172
Therefore, by probability the answer will be 91.7%

Answer:
A) -30 - x = 10 and -30 - x = –10
Step-by-step explanation:
Part 1:
1) Isolate the variable x
-30 - x = 10
-x = 40
2) Multiply both sides by -1
x = -40
Therefore -30 - x = 10 is correct
Part 2:
1) Isolate the variable x
-30 - x = –10
-x = 20
2) Multiply both sides by -1
x = -20
Therefore -30 - x = –10 is also correct
Final Answer: -30 - x = 10 and -30 - x = –10
