Step-by-step explanation:

5 which is the number of tulips divide by 15 which is the total number of flowers

(I'm not sure tho)

The experimental probability that Amelie picks a tulip next is 1/3, calculated by dividing the number of tulips (5) she has already picked by the total number of flowers picked (15).

The experimental probability that the next flower Amelie picks will be a tulip is based on her past experience of picking flowers. Since she has picked 15 flowers and 5 were tulips, we divide the number of tulips by the total number of flowers picked to get the probability of picking a tulip.

To calculate this, use the formula for experimental probability: Probability = (Number of successful outcomes) / (Total number of trials). In Amelie's case, this would be 5 tulips divided by 15 flowers, giving a probability of 1/3, or approximately 0.333.

Thus, the experimental probability of picking a tulip next is 1/3.aa

Answer:

clockwise and end up in the 3rd quadrant

Step-by-step explanation:

That's how you're supposed to graph angles. Also, 180<210<270, which are the parameters for the 3rd quadrant

In the coordinate plane, when you graph a positive 210  degrees angle you go option (C) counter-clockwise and end up in the 3rd quadrant

A coordinate plane is a tool used for graphing points, lines, and other objects. It functions like a map that follows directions from one point to another.

A figure which is formed by two rays or lines that shares a common endpoint is called an angle

Given,

We have to plot a positive 210 degree angle

So the movement will be in counter clockwise direction and angle 210 degrees in the third quadrant

Therefore when you graph positive 210 degrees you go in counterclockwise direction and end up in the 3rd quadrant

Hence, In the coordinate plane, when you graph a positive 210  degrees angle you go option (C) counter-clockwise and end up in the 3rd quadrant

Answer:

Percent Error:: 12/36 = 33 1/3 %

Step-by-step explanation:

Final answer:

To find the percent error when estimating marbles in a jar, you subtract the estimated value from the actual value, divide by the actual value, and multiply by 100. In this case, the percent error is 8.54%.

Explanation:

To find the percent error, you first calculate the absolute error by subtracting the estimated value from the actual value. Then, divide the absolute error by the actual value and multiply by 100 to get the percent error.

Calculate absolute error: 82 (actual) - 75 (estimated) = 7

Percent error formula: (Absolute error / Actual value) x 100%

Percent error = (7 / 82) x 100% = 8.54%

1/4=3/12

2/3=8/12

5/12=375

375/5=75

1/12=75

75*12=900

10/12=5/6

5/6=750

Answer:

  $2355.06

Step-by-step explanation:

Use the compound interest formula, filling in the numbers you know. Then solve for the number you don't know.

  A = P(1 +r/n)^(nt)

where A is the account balance, P is the amount invested, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years.

Filling in the given values, we have ...

  4000 = P(1 +.053/52)^(52·10) = P(1.6984738)

  P = 4000/1.6984738 ≈ 2355.06

You would need to deposit $2355.06 in order to have $4000 in 10 years.

Answer:A contractor finds that Crew A takes 5(1/2) hours to construct a retaining wall and Crew B can do the same job in 7(1/2) hours.

If Crew A and Crew B work together, how long will it take them to construct the retaining wall?

a) Let h = the time to complete the job. Write the equation you would use to solve this problem.

:

let the completed job = 1, each will do a fraction of the job which adds up to 1

h%2F5.5 + h%2F7.5 = 1

Step-by-step explanation:f means fraction 2/5.5 2/7.5

Final answer:

Together, they will complete the wall in approximately 3.34 hours (about 3 hours and 20 minutes).

Explanation:

To determine how long it will take for crew A and crew B to construct a retaining wall together, we can use the concept of rates of work. We first find the rate at which each crew can complete the job individually and then combine their rates.

Crew A takes 5.5 hours to construct the retaining wall, which means their rate of work is 1 wall per 5.5 hours or 1/5.5 walls per hour.

Crew B takes 8.5 hours, so their rate is 1 wall per 8.5 hours or 1/8.5 walls per hour.

When both crews work together, you can add their rates:

Rate of A + Rate of B = Combined Rate

1/5.5 + 1/8.5 = Combined Rate

To find the combined rate, you find a common denominator and add the fractions:

Combined Rate = (8.5 + 5.5) / (5.5 × 8.5)

Combined Rate = 14 / 46.75

The combined rate is approximately 0.2995 walls per hour. To find the total time it takes for both crews to construct the wall, you take the reciprocal of the combined rate:

Total time = 1 / Combined Rate

Total time = 1 / 0.2995

This gives us the total time of approximately 3.34 hours (or roughly 3 hours and 20 minutes) for both crews working together to construct the retaining wall.

The hypothesis test in question is a left-tailed test based on the claim that less than 8% of the subjects would experience headaches. With a z-value of 0.233126 and a stated significance level of 0.01, the D-value of 0.592168 suggests that there is not enough evidence to reject the null hypothesis.

Explanation:

When analyzing the clinical trial data for a drug used to treat asthma, we consider the provided information regarding the subjects experiencing headaches. With 21 out of 250 subjects reporting headaches, and a claim that less than 8% would experience this side effect, we set up a hypothesis test to determine if the claim holds at a 0.01 significance level. Given that the alternative hypothesis is prop < 0.08, which strictly tests for proportions lower than 8%, this is a left-tailed test.

The test statistic provided is a z-value of 0.233126, and the decision value (D-value) is 0.592168. Since the significance level is 0.01 and the test is left-tailed, we check if the z-value falls into the critical region defined by the significance level. If the z-value corresponds to a p-value lower than 0.01, we would reject the null hypothesis. Otherwise, we would fail to reject the null hypothesis.

In the context of large-sample hypothesis tests, as noted in a paragraph mentioning that 'the large-sample 1 - PropZTest provides the approximate p-value', when the p-value from the normal approximation is close to the level of significance, the exact p-value should be calculated using binomial probabilities. However, because the statistical calculator has provided a D-value (which relates to the p-value) significantly greater than the 0.01 significance level, we have sufficient evidence to fail to reject the null hypothesis, implying that there is not enough evidence to support the claim that less than 8% of treated subjects experienced headaches.

Answer:Exponential functions follow all the rules of functions. However, because they also make up their own unique family, they have their own subset of rules. The following list outlines some basic rules that apply to exponential functions

Step-by-step explanation:The parent exponential function f(x) = bx always has a horizontal asymptote at y = 0, except when b = 1. You can’t raise a positive number to any power and get 0 or a negative number.

This rule is true because you can raise a positive number to any power. However, the range of exponential functions reflects that all exponential functions have horizontal asymptotes. All parent exponential functions (except when b = 1) have ranges greater than 0, or

The order of operations still governs how you act on the function. When the idea of a vertical transformation applies to an exponential function, most people take the order of operations and throw it out the window. Avoid this mistake.

You can’t multiply before you deal with the exponent.

You can’t have a base that’s negative. For example, y = (–2)x isn’t an equation you have to worry about graphing in pre-calculus. If you’re asked to graph y = –2x, don’t fret. You read this as “the opposite of 2 to the x,” which means that (remember the order of operations) you raise 2 to the power first and then multiply by –1. This simple change flips the graph upside down and changes its range to

A number with a negative exponent is the reciprocal of the number to the corresponding positive exponent. For instance, y = 2–3 doesn’t equal (–2)3 or –23. Raising any number to a negative power takes the reciprocal of the number to the positive power

When you multiply monomials with exponents, you add the exponents. F

When you have multiple factors inside parentheses raised to a power, you raise every single term to that power. For instance, (4x3y5)2 isn’t 4x3y10; it’s 16x6y10.

When graphing an exponential function, remember that the graph of an exponential function whose base number is greater than 1 always increases (or rises) as it moves to the right; as the graph moves to the left, it always approaches 0 but never actually get there. For example, f(x) = 2x is an exponential function, as is

The table shows the x and y values of these exponential functions. These parent functions illustrate that, as long as the exponent is positive, the graph of an exponential function whose base is greater than 1 increases as x increases — an example of exponential growth — whereas the graph of an exponential function whose base is between 0 and 1 decreases towards the x-axis as x increases — an example of exponential decay.

The graph of an exponential function who base numbers is fractions between 0 and 1 always rise to the left and approach 0 to the right. This rule holds true until you start to transform the parent graphs.

A dot chart or dot plot is a statistical chart consisting of data points plotted on a fairly simple scale, typically using filled in circles. There are two commons, yet very different, versions of the dot chart.

Given that, Kiki has a piece of string that she cuts into smaller pieces. This line plot shows the lengths of the pieces. Raj has a piece of string that is 12 as long as Kiki's third-longest piece.

The third-longest piece = 4 1/2 in

The length of Raj's string = 4 1/2 x 12 = 9/2 x 12 = 54

Hence, the length of Raj's string is 54 in long.

18 lengh times 10 width = 180

Final answer:

To calculate the probability that Bob will draw $15 in tokens, we need to calculate the probability of him drawing a $5 token from the cup (1/3) and a $10 token from his pocket (2/3) and then multiply these probabilities to get the total probability (2/9).

Explanation:

The probability that Bob will draw $15 in tokens consists of two steps: drawing from the coin cup and then drawing from his pocket. We must calculate the probability for each stage and, finally, multiply these probabilities together to get the total probability of drawing $15.

From the cup, Bob can draw either a $1 token or a $5 token. To get a total of $15, Bob would need to draw a $5 token from the cup, since the highest value in his pocket is $25 and 1+25 is greater than 15. There are two $5 tokens in the cup among six tokens in total, so the probability of drawing a $5 token is 2/6 or 1/3.

Having drawn a $5 token, he now needs to draw a $10 token from his pocket to reach the total of $15. In his pocket, he has two $10 tokens and one $25 token, making three tokens in total. The probability of drawing a $10 token is therefore 2/3.

By multiplying these probabilities, we get the total probability of drawing $15 in tokens: (1/3) * (2/3) = 2/9.

Therefore, the probability that Bob will draw $15 in tokens is 2/9.

Answer:

The buildings height was 64.23 (meters) to 2dp

Step-by-step explanation:

This is because the pole shadow = 44.3333% increase to get to 3ft

Seeing that 1.67 was the shadow and beside it the building shows 44.5 we just multiply it by the percentage and to not add one (1) to the decimal to add if not adding or showing what 44.33% becomes.

44.5 x 1.443333 =64.2283185  and sum (add) as its an increase = (44.5 + 19.72831 = 64.2283185) So 19.73 to 2dp is the difference without the 1 used and without being seen.

This is the hidden increase as we just say 44.33% of 44.5 ft But as we used the 1. to represent the x100.

We find 44.33% of 44.5 finds us the buildings exact measure to 2dp = 64.22m
