In the Math Club, 7 of the 20 girls are seniors, and 4 of the 14 boys are seniors. What is the probability of randomly selecting a boy or a senior to represent the Math Club at a statewide math contest?

Answers

34 In All. 14 boys (14/34) 11 Seniors, - 4 so we don't double count. (14/34) + (7/34)


The answer is 21/34.

There are in total 34 children: 20 girls + 14 boys = 34 children
There are in total 11 seniors: 7 senior girls + 4 senior boys = 11 senior children

When we have two events that do not occur together, so only one of the events can happen (there is OR in a sentence), then we use the addition rule and add up probabilities of the events. We have two events not occurring together:
1. The probability of selecting a boy is 14/34 (because there are 14 boys among 34 children).
2. The probability of selecting a senior is 11/34 (because there are 11 seniors among 34 children).


Now, we just need to add them up. However, we have already counted 4 senior boys in the probability of the first event and thus, must subtract the probability of selecting a senior boys (4/34):
14/34 + 11/34 - 4/34 = (14+11-4)/34 = 21/34

6 sweets cost 24p altogether how much do 5 sweets cost

Answers

24 divided by 6 equals 4. Each sweet is worth 4p. If you multiply 5 by 4 you get 20, so the answer is 5 sweets cost 20p.

To calculate the cost of 5 sweets when 6 sweets cost 24p, divide the total cost by the number of sweets to determine the cost of one sweet, then multiply by 5. The cost for 5 sweets is 20p.

To find out how much 5 sweets cost when 6 sweets cost 24p altogether, we first need to calculate the cost of one sweet. We divide the total cost by the number of sweets to get the cost per sweet. Here's how it's done:

Find the cost of one sweet by dividing the total cost of 6 sweets (24p) by 6: Cost per sweet = 24p / 6 = 4p.Now, multiply the cost per sweet by the number of sweets you want to find the cost for, which in this case is 5: Cost for 5 sweets = 4p / sweet × 5 sweets = 20p.

Therefore, 5 sweets would cost 20p.

Final answer:

Leslie can determine which option will give her more yogurt by comparing the weights of the two options.

Explanation:

To determine which option will give Leslie more yogurt, she needs to compare the weights of the two options. First, she needs to convert the weight of the first option from pounds to ounces. Since 1 pound is equal to 16 ounces, the 2 pound container is equal to 32 ounces. Next, she can compare the weights of the two options. The first option is 32 ounces and the second option is 5 containers of 6 ounces each, which is a total of 30 ounces. Therefore, the first option will give Leslie more yogurt.

use analytic methods to find the extreme values of f(x)= (1/x) + lnx on the interval 0.5 ≤ x ≤ 4 and where they occur

Answers

f(x) = (1/x) + ln x
At the extreme values, f'(x) = 0
f'(x) = -1/x^2 + 1/x = 0
(x - 1)/x^2 = 0
x - 1 = 0
x = 1

f(1) = 1/1 + ln 1 = 1

Therefore, the extereme value is 1 and occurs at x = 1.

What is 0.98 rounded to the nearest thousandth?

Answers

0.98 is already rounded
it may also be asking for 0.980, which is equal but shows the thousandth place

The number 0.98 already has a zero in the thousandths place and no further digits; hence it remains as 0.980 when rounded to the nearest thousandth.

The given number, 0.98, when rounded to the nearest thousandth, does not change because it has a zero in the thousandths place. To round a number to the nearest thousandth, you look at the digit in the ten-thousandths place. If this digit is 5 or greater, you round up.

If it is less than 5, you keep the digit in the thousandths place as it is. Since 0.98 has a zero in the thousandths place already and there are no further digits, it remains as 0.980 when rounded to the nearest thousandth.

Hope this helps!! and if you ever need anything else just ask! :)

Answer:

A round number is less accurate, but easier to use, because you get rid of certain decimals.

There are some rules to do this:

If we want to round a number to the nearest tenth, we have to look what's the unit after it, if that unit is more than 5, we round the tenth to the upper number. For example, 10.66 would be rounded to 10.7.If we want to round a number, and the next digit is lower that 5, we just maintain the same digit. For example, 10.44 would be rounded to 10.4However, there's a specific case, if we want to round a number to the tenth, and the following digit is 5, we could round up or round down the tenth digit. If the digit we want to round is pair, then we maintain the same digit, if it's odd, we can round to the upper digit. For example, 10.65 would be rounded to 10.6, and 10.75 would be rounded to 10.8

Therefore, according to these rules, the round number would be $3.8 and $3.8

The problem involves empirical probability. The table shows the breakdown of 95 thousand single parents on active duty in the U.S. military in a certain year. All numbers are in thousands and rounded to the nearest thousand. Use the data in the table to find the probability that a randomly selected single parent in the U.S. military is in the army.

Answers

Final answer:

The data provided does not include specific information needed to calculate the empirical probability of a randomly selected single parent in the U.S. military being in the Army.

Explanation:

Unfortunately, the provided information does not give specific numbers for single parents actively serving in the different branches of the U.S. military, including the Army. Therefore, it is not possible to accurately calculate the empirical probability this question is asking for. However, if such data were available, you would calculate the empirical probability of a randomly selected single parent in the U.S. military being in the Army by dividing the number of single parents in the Army by the total number of single parents on active duty.

if the roots of the equation (a2+b2)x2-2(ac+bd)x+(c2+d2)=0 are equal, prove that a/b=c/d ...?

Answers

Roots are real only when the discriminant d is positive or 0. 


Since d = -4(ad - bc)^2, then roots are real only when ad - bc = 0, ie, ad = bc. 


Now, using the quadratic formula we get just one root = -(ac + bd)/(a^2 + b^2). 

---------------------------------------... 


You can also check: 


(x + (ac + bd)/(a^2 + b^2))^2 = x^2 + 2(ac + bd)/(a^2 + b^2)x + (ac + bd)^2/(a^2 + b^2)^2 and note 


(ac + bd)^2 = a^2c^2 + 2abcd + b^2d^2 = a^2c^2 + abcd + abcd + b^2d^2 = a^2c^2 + a^2d^2 + b^2c^2 + b^2d^2 = (a^2 + b^2)(c^2 + d^2). 


So x^2 + 2(ac + bd)/(a^2 + b^2)x + (ac + bd)^2/(a^2 + b^2)^2 = x^2 + 2(ac + bd)/(a^2 + b^2)x + (c^2 + d^2)/(a^2 + b^2)

Answers

Final answer:

The variances for the samples were calculated, and then the probability of each distinct variance value was found. The results were summarized in a table showing the probability distribution of the variances.

Explanation:

The variance of a sample is calculated using the formula:
s^2 = Σ ( xi - X_bar )^2 / (n - 1).
Where 'xi' represents each value in the sample, 'X_bar' is the mean of the sample and 'n' is the number of values in the sample. Let's calculate the variance for each of these samples:

1,1: variance = 01,3: variance = 21,8: variance = 493,1: variance = 23,3: variance = 03,8: variance = 258,1: variance = 498,3: variance = 258,8: variance = 0

Next, find the probability of each distinct variance value by counting the number of times it occurs and dividing by the total number of samples (9 in this case). The sampling distribution of the variances with probabilities looks something like this:

Variance = 0 : Probability = 3/9 = 0.33Variance = 2 : Probability = 2/9 = 0.22Variance = 25 : Probability = 2/9 = 0.22Variance = 49 : Probability = 2/9 = 0.22

To find out how fast a tree grows, you can measure its trunk. A giant red oak's diameter was 248 inches in 1965. The tree's diameter had grown to 251 inches in 2005. Find the average rate of change in the diameter of the tree per year.

Answers

For starters, determine what two things are changing, in this case, the question tells you it's the diameter and the year. Next, determine by how much these two are changing. For the year, subtract the most recent year by the oldest year, so 2005-1965=40 years. For the diameter, subtract the diameter of the most recent year by the diameter of the oldest year, so 251-248=3. Now, use the question to get your ratio. The question asks for "diameter of the tree per year," so you would divide the change in diameter by the change in year, so 3/40 inches per year would be your ratio.
