In a bag there are 3 pink, 5 blue, 3 yellow, and 1 purple jellybeans. What is the probability of picking a jellybean that is NOT blue? Is this theoretical or experimental probability? Why?
!:
If you could mark as brainliest that would be great!
Answer:
The probability of picking a jellybean that is NOT blue is:
(number of jellybeans that are not blue) / (total number of jellybeans)
= (3 + 3 + 1) / (3 + 5 + 3 + 1)
= 7/12
This is theoretical probability because it is based on the assumption that each jellybean has an equal chance of being picked, without actually performing the experiment.
Answer: The probability of picking a jellybean that isn’t blue is has a 7/12 chance. This is a theoretical probability because you never can exactly tell if you’re gonna pick blue or not.

Answer:
1.32km (answer might differ slightly due to different values of speed of sound, in the range of 320 to 340 ms-1)
Step-by-step explanation:
Speed of lightning = 3 x 10^8 m/s (same as speed of light)
Speed of sound = 330 m/s (most common answer for speed of sound)
Let the time taken for lightning be T seconds
Time taken for thunder to reach her = (T + 4) seconds
Hence, an equation can be formed
Distance between lightning and her = Distance between thunder and her
Distance = Speed x Time
T(3x 10^8) = (T+4)(330)
((3 x 10^8) - 330)T = 4(330)
Solving, T = 4.40 x 10^-6
Hence,
Distance from storm = (4.40 x 10^-6)(3 x 10^8) metres
= 1320m
= 1.32 km
Answer:
0.8 miles(as kilometers 1.28748)
Step-by-step explanation:
You have 4 seconds and then you divide by 5 and then you get 0.8 miles turn that into kilometers and you get 1.28748.
Last week, a chocolate shop sold 9 ounces of white chocolate. It sold 9 9/10 times as much milk chocolate as white chocolate. How many ounces of milk chocolate did the shop sell?
please answer asap
Solving the Question
We're given:
9 ounces of white chocolate sold\(9\dfrac{9}{10}\) times as much milk chocolate as white chocolate soldIf the shop sold " \(9\dfrac{9}{10}\) times as much milk chocolate as white chocolate", we must multiply \(9\dfrac{9}{10}\) by the amount of white chocolate sold to find the amount of milk chocolate sold.
Multiply \(9\dfrac{9}{10}\) by 9 ounces:
\(9\dfrac{9}{10}\times9\)
Convert the fraction into an improper fraction:
\(=\dfrac{99}{10}\times9\)
Multiply:
\(=\dfrac{891}{10}\)
AnswerThe shop sold \(\dfrac{891}{10}\) ounces of milk chocolate.

Use a normal approximation to find the probability of the indicated number of voters . In this case , assume that 144 eligible voters aged 18-24 are randomly selected . Suppose a previous study showed that among eligible voters aged 18-24 , 22 % of them voted . Probability that exactly 36 voted
The probability that exactly 36 of 144 eligible voters voted is
Using a normal approximation, the probability that exactly 36 of 144 eligible voters aged 18-24 voted can be estimated.
To find the probability that exactly 36 out of 144 eligible voters voted, we can use a normal approximation to the binomial distribution. Here's how to calculate it:
1. Calculate the mean (μ) of the binomial distribution:
\(\(\mu = n \cdot p\)\)
where n is the number of trials (144) and p is the probability of success (22% or 0.22).
\(\(\mu = 144 \cdot 0.22 = 31.68\)\)
2. Calculate the standard deviation (σ) of the binomial distribution:
\(\(\sigma = \sqrt{n \cdot p \cdot (1 - p)}\)\)
\(\(\sigma = \sqrt{144 \cdot 0.22 \cdot (1 - 0.22)} = \sqrt{144 \cdot 0.22 \cdot 0.78} = \sqrt{30.7584} = 5.54\)\)
3. Apply continuity correction:
Since we're using a normal approximation, we adjust the range by 0.5 on each side.
4. Calculate the probability using the normal distribution:
P(X = 36) ≈ P(35.5 < X < 36.5)
We use the continuity-corrected range.
\(\(P(X = 36) \approx P\left(\frac{{35.5 - \mu}}{{\sigma}} < Z < \frac{{36.5 - \mu}}{{\sigma}}\right)\)\)
Z represents the standard normal distribution.
\(\(P(X = 36) \approx P\left(\frac{{35.5 - 31.68}}{{5.54}} < Z < \frac{{36.5 - 31.68}}{{5.54}}\right)\)\)
5. Look up the values in the standard normal distribution table or use a calculator to find the probability.
Please note that the normal approximation to the binomial distribution is valid when \(\(n \cdot p \geq 5\)\) and \(\(n \cdot (1 - p) \geq 5\)\). In this case, \(\(144 \cdot 0.22 = 31.68 \geq 5\)\) and \(\(144 \cdot (1 - 0.22) = 112.32 \geq 5\)\), so the approximation can be used.

Answer:
area = 28.27
circumference = 18.85
Step-by-step explanation:
Using the formulas for area,

d = 2r
Solving for area,
A = 1/4 πd^2 = 1/4 × π × 6^2 ≈ 28.27yd²
Using the formulas for circumference,
C = 2 πr
d = 2r
Solving for circumference,

The table below is for a function A=f(d), which gives the amount of money A (in billions of dollars) in bills of denomination circulating in US currency in 2005. For example according to the table values below there were $60.2 billion worth of $50 bills in circulation.
Tables are used to show the relationship between related quantities. From the given table, the value of f(10) is 14.8
See attachment for the table of \(A = f(d)\)
To solve for f(10), we simply locate the value of A when d = 10
From the table
A = 14.8 when d = 10
This means that:
\(A =f(10) = 14.8\)
Hence:
\(f(10) = 14.8\)

What is the approximate area of a circle with diameter 6?
Answer: 28.27
Step-by-step explanation:
First, you can turn the diameter into a radius, giving you 3. Since the equation of an area in a circle is A=πr^2, you must square 3, giving you 9. Now you must multiply 9 with Pi, which is 3.14159265358, but just 3.14 for short. With that, you get about 28.27 as area.

I WILL GIVE BRAINLIEST! ONLY ANSWER IF YOU KNOW ITS CORRECT! (08.04 MC)Mia creates a box plot using 28, 34, 40, 24, 44, 49, and 32 as the data. Which of the following box plots shows the data accurately?
9514 1404 393
Answer:
(d)
Step-by-step explanation:
When the data is put in order, the values are ...
24, 28, 32, 34, 40, 44, 49
The middle value is 34. This is the median, where the line in the middle of the box plot is located. Only one answer choice has this correctly placed.
__
When the median is removed, the data set is divided into two parts:
24, 28, 38 and 40, 44, 49
The middle value of each of these will be the lower and upper quartiles, the ends of the box in the box plot. Those are 28 and 44.
So, the box plot has whiskers that extend to the extreme data points of 24 and 49, box ends at 28 and 44, and a median line at 34. The last choice matches this description.
John has to type a 2,000-word business research report, and he types at a rate of 40 words per minute. The function R(m) = 2,000 40 m can be used to calculate the number of minutes required to finish after m minutes of typing. What is the domain for function R in this context?
The domain for the function is m ≥ 0
Given data ,
Let the function be represented as f ( x )
Now , the value of the function is
R ( m ) = ( 2000/40 ) - m
R(m) = 50 - m
The domain of a function is the set of all possible input values for which the function is defined. In this case, since we are dealing with time, the domain of the function should be non-negative values of m, as negative values of m do not make sense in the context of typing time.
Hence , the domain of function R is m ≥ 0
