In a new lottery game, contestants pick 5 numbers (1-9 inclusive) and must guess exactly 3 correct in order to win. What’s the probability of winning this lottery?
Answer: 0.6%
Step-by-step explanation:
We have a selection of 5 numbers, in those selection we have 3 combinations of 3 consecuitve numbers (because the numbers must be in correct order).
The first 3
The 3 in the middle
the last 3.
So a contestant has 3 combinations were he wins.
Now, the number of possible combinations of the 9 numbers given is:
For the first number we have 9 options.
For the second number we have 8 options (because we already selected one)
For the last number we have 7 options (because we already selected 2 numbers)
Then the number of possible combinations is
10*9*8 = 504
The probabilty of winning will be equal to the number of combinations that the contestant has (3) divided by the total number of combinations, this is:
p = 3/504 = 0.006 or 0.006*100% = 0.6%

James and Reggie both collect old coins. Together, they have a total of 60 coins. If James would agree to give 1/4 of his coins to Reggie, they would then have exactly the same number of coins. How many more cons does James have (compared to the number of coins Reggie has)?
Answer:
James has 20 more coins than Reggie
Step-by-step explanation:
Given:
Total number of coins with James and Reggie = 60
If James would agree to give 1/4 of his coins to Reggie, they would then have exactly the same number of coins
To find: number of coins with James and Reggie
Solution:
Let x denote number of coins with James and y denote number of coins with Reggie.
According to question,
[tex]x+y=60\\x-\frac{x}{4} =y+\frac{x}{4} \\x-y=\frac{2x}{4} \\x=2y[/tex]
Put [tex]x=2y[/tex] in [tex]x+y=60[/tex]
[tex]2y+y=60\\3y=60\\y=\frac{60}{3}=20\\ x=2y=2(20)=40[/tex]
So,
number of coins with James = 40
number of coins with Reggie = 20
James has 20 more coins than Reggie

A professional soccer player buys 16 acers of land. he plans to build a house on the land but wants to use 2/8 of the land to put his own soccer field and facility on. how many acres of land will the soccer player need for his soccer field and facility?
Answer:
Step-by-step explanation:
The professional soccer player buys 16 acres of land.
He wants to use [tex]\frac{2}{8}[/tex] of the land to put his own soccer field and facility on.
All we have to do is find [tex]\frac{2}{8}[/tex] of 16 acres.
[tex]\frac{2}{8}[/tex] of 16 acres:
[tex]\frac{2}{8}[/tex] * 16 = 4 acres
He will need 4 acres out of the 16 acres for his soccer field and facility.
Leon verified that the side lengths 21, 28, 35 form a Pythagorean triple using this procedure. Step 1: Find the greatest common factor of the given lengths: 7 Step 2: Divide the given lengths by the greatest common factor: 3, 4, 5 Step 3: Verify that the lengths found in step 2 form a Pythagorean triple: 3 squared + 4 squared = 9 + 16 = 25 = 5 squared Leon states that 21, 28, 35 is a Pythagorean triple because the lengths found in step 2 form a Pythagorean triple. Which explains whether or not Leon is correct?
Answer: Leon was wrong by using the greatest common factor to determine that the numbers are a Pythagorean triple.
Step-by-step explanation: The numbers that Leon used in his calculations which are, 21, 28, and 35 are actually a Pythagorean triple and this can be determined by using the Pythagoras' theorem which states that,
AC² = AB² + BC²
Where AC is the longest side, and AB and BC are the other two sides.
Substituting for the given values, we now have
35² = 28² + 21²
1225 = 784 + 441
1225 = 1225
Since both sides of the equation are equal, we can conclude that the numbers form a Pythagorean triple.
However, dividing the numbers by their greatest common factor does not prove that it is a Pythagorean triple. This process cannot be successfully applied to other Pythagorean triples, and is best described as a chance event.
For example, the numbers 21, 20 and 29 are Pythagorean triples and they have no common factor. Similarly, 6, 8 and 10 are also Pythagorean triples and their greatest common factor is 2. This too is not sufficient to prove that they form a Pythagorean triple.
The only prove that is sufficient enough is to substitute the numbers into the Pythagoras theorem as stated in the calculation above, and the result must show the left hand side of the equation to be equal to the right hand side of the equation.

Step-by-step explanation:
The total number of crayons in the box
9 red crayons, 5 blue crayons, and 8 yellow crayons = 22
The number that are blue or yellow = 5+8 = 13
P (blue or yellow) = number that are blue or yellow / total
= 13/22
Answer:

2. Expand the right side of the equation:
[tex]\[y + 6 = 5x - 20\][/tex]
3. Move the constant term (6) to the right side by subtracting 6 from both sides:
[tex]\[y = 5x - 20 - 6\]\\y = 5x - 26\][/tex]
Now, the equation is rearranged so that \(y\) is expressed in terms of[tex]\(x\): y= 5x - 26[/tex]

Jen rode her bike 1/5 of a mile to her friend's house. It took her 5 minutes to get there. What was Jen's speed?
Jen's speed is 0.04 miles per minute.
Explanation:To find Jen's speed, we need to divide the distance she traveled by the time it took her to get there. In this case, Jen traveled 1/5 of a mile and it took her 5 minutes. To find her speed in miles per minute, we divide the distance (1/5 mile) by the time (5 minutes):
Speed = Distance ÷ Time
Speed = 1/5 mile ÷ 5 minutes
To simplify the calculation, we can convert 1/5 mile to a decimal by dividing 1 by 5:
1/5 = 0.2
Now we can divide 0.2 by 5 to find Jen's speed:
0.2 ÷ 5 = 0.04
Therefore, Jen's speed is 0.04 miles per minute.
A public bus company official claims that the mean waiting time for bus number 14 during peak hours is less than 10 minutes. Karen took bus number 14 during peak hours on 18 different occasions. Her mean waiting time was 7.8 minutes with a standard deviation of 2.5 minutes. At the 0.01 significance level, test the claim that the mean is less than 10 minutes.
Answer:
We conclude that the mean waiting time is less than 10 minutes.
Step-by-step explanation:
We are given that a public bus company official claims that the mean waiting time for bus number 14 during peak hours is less than 10 minutes.
Karen took bus number 14 during peak hours on 18 different occasions. Her mean waiting time was 7.8 minutes with a standard deviation of 2.5 minutes.
Let [tex]\mu[/tex] = mean waiting time for bus number 14.
So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu \geq[/tex] 10 minutes {means that the mean waiting time is more than or equal to 10 minutes}
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] < 10 minutes {means that the mean waiting time is less than 10 minutes}
The test statistics that would be used here One-sample t test statistics as we don't know about the population standard deviation;
T.S. = [tex]\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }[/tex] ~ [tex]t_n_-_1[/tex]
where, [tex]\bar X[/tex] = sample mean waiting time = 7.8 minutes
s = sample standard deviation = 2.5 minutes
n = sample of different occasions = 18
So, test statistics = [tex]\frac{7.8-10}{\frac{2.5}{\sqrt{18} } }[/tex] ~ [tex]t_1_7[/tex]
= -3.734
The value of t test statistics is -3.734.
Now, at 0.01 significance level the t table gives critical value of -2.567 for left-tailed test.
Since our test statistic is less than the critical value of t as -3.734 < -2.567, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region due to which we reject our null hypothesis.
Therefore, we conclude that the mean waiting time is less than 10 minutes.
Using the t-distribution, it is found that since the test statistic is less than the critical value for the left-tailed test, it is found that there is enough evidence to support the claim that the mean is less than 10 minutes.
At the null hypothesis, it is tested if the mean is of at least 10 minutes, that is:
[tex]H_0: \mu \geq 10[/tex]
At the alternative hypothesis, it is tested if it is less than 10 minutes, that is:
[tex]H_1: \mu < 10[/tex]
We have the standard deviation for the sample, thus, the t-distribution is used. The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean. [tex]\mu[/tex] is the value tested at the null hypothesis. s is the standard deviation of the sample. n is the sample size.For this problem, the values of the parameters are: [tex]\overline{x} = 7.8, \mu = 10, s = 2.5, n = 18[/tex]
Hence, the value of the test statistic is:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{7.8 - 10}{\frac{2.5}{\sqrt{18}}}[/tex]
[tex]t = -3.73[/tex]
The critical value for a left-tailed test, as we are testing if the mean is less than a value, with a 0.01 significance level and 18 - 1 = 17 df is of [tex]t^{\ast} = -2.57[/tex]
Since the test statistic is less than the critical value for the left-tailed test, it is found that there is enough evidence to support the claim that the mean is less than 10 minutes.

What is 1,289,845 rounded to the nearest thousand?
Answer:
1,290,000
Step-by-step explanation:
Answer:
1,290,000
Step-by-step explanation:
If we are rounding to the nearest thousand, then we are finding the number in the hundredth's and rounding it.
From 1-9 If it's less than 5, round down. If it's 5 or more, round up.
At this case, it is 8 in the hundredths and nine in the thousandths. Since 8 is 5 or greater, you round it up to 1000, but the thousandth's place has a nine, which nine plus 1 is 10.
Therefore, 1,289,845 rounded up is 1,290,000.
