suppose a research team takes a simple random sample of 100 parma wallabies. in this sample, the tails of the wallabies have a mean length of 46 centimeters and a standard deviation of 2.6 centimeters.

What percent of the time could a simple random of 100 parma wallabies have a sample mean that is not in the 95% confidence interval?

5%
0%
2.5%
20%

Answers

Answer: choice A) 5%

------------------------------------
------------------------------------

Explanation:

Saying "95% confidence interval" means that if we made a simple random 
sample (SRS) of 100 wallabies, and computed the sample mean, then 95% of the sample means will be in the confidence interval. The remaining 5% (100%-95% = 5%) of the sample means will fall outside the confidence interval.

What is the missing term in the factorization

Answers

Hello,

The answer is 3 • (2x + 5) • (2x - 5).
Final answer:

To find the missing term in the factorization, we rewrite the equation in the form of ax^2 + bx + c = 0, equate the coefficients and solve for the term. The missing term is -25.

Explanation:

To find the missing term in the factorization, we can rewrite the given equation in a general form of the quadratic equation like ax^2 + bx + c. In our case, this would be:12x^2 - 3(4x^2 - 10x + ?) = −75. Here, 'a' has a coefficient of 12, 'b' is -10 multiplied by 3 (the '3' outside the brackets), and 'c' is ? multiplied by 3. By equating the coefficients on both sides of the equation, we can solve for the missing term '?'. Therefore, the missing term is '? = -75 / 3' or '? = -25'.

If two fair dice are rolled 10 times, what is the probability of at least one 6 (on either die) in exactly five of these 10 rolls?

Answers

About 10.84% is the answer. The exact value is (5^10)7(11^5)/(6^18) First, determine the probability that you'll get at least one 6 on a single throw of two dice. Of the 36 ways that two dice can fall, eleven of them have at least one 6. So the probability is 11/36 for a single throw. Now what's the probability of exactly 1 throw out of 10 having at least one 6? That would be + 11/36 * (25/36)^9 + 25/36 * 11/36 * (25/36)^8 + (25/36)^2 * 11/36 * (25/36)^7 ... + (25/36)^9 * 11/36 or 11/36 * (25/36)^9 * 10 In general the probability of exactly n events out of m having a condition with probability p happen will be p^n*(1-p)^(m-n) multiplied by the number of ways you can select n out of m items. And since the formula for selecting n of m items is m!/(n!(m-n)!), the overall formula becomes m!/(n!(m-n)!)p^n*(1-p)^(m-n) so 10!/(5!5!)*(11/36)^5*(25/36)^5 = 252*(161051/60466176)*(9765625/60466176) = (5^10)7(11^5)/(6^18) ~ 0.108402426 So the exact answer is (5^10)7(11^5)/(6^18) and the approximate answer is 0.108402426 which is about 10.84%

Which of the following represents ninth root of x to the seventh power in exponential form?

Answers

The exponent is 7/9 like this x^⁷⁄₉.

Answer:

[tex]x^{\frac{7}{9}}[/tex]

Step-by-step explanation:

write ninth root of x to the seventh power in exponential form

[tex]\sqrt[9]{x^7}[/tex]

To write the radical in exponential form we use the below property

[tex]\sqrt[n]{x^a} = x^{\frac{a}{n}}[/tex]

The radical becomes the base of the fraction

[tex]\sqrt[9]{x^7}=x^{\frac{7}{9}}[/tex]

we cannot simplify the fraction.

A certain sequence is defined such that the th term in the sequence is equal to n n how much greater is the 10th term th term in the sequence?

Answers

Treat this like a function question, only instead of f(n) = n^2 + 1, you’re told that the nth term equals n^2 + 1. Different language, same exact result:

The 7th term will be 7^2 + 1 = 50, and the 10th term will be 10^2 + 1 = 101. 101 is 51 greater than 50. 

Final answer:

To find how much greater the 10th term is compared to the nth term in a sequence, we need the sequence's rule. Assuming the rule is n^2, the 10th term is 10^2. The difference would be 10^2 - n^2, but without the value for n or a clear sequence definition, the numerical difference remains unknown.

Explanation:

The question appears to be asking for the 10th and nth terms of a defined sequence, but there seems to be a typo or missing information specifying the rule for the sequence. To find how much greater the 10th term is compared to the nth term, we would first need the explicit formula for the sequence. If the sequence is defined such that the nth term is n2, then the 10th term would be 102, and the nth term would be n2. The difference between the two terms is then 102 - n2. Without the value for n or a proper sequence definition, we cannot find the actual numerical difference.

solve the system by substitution. -4.5-2y=-12.5 , 3.35x-y=-0.75

Answers

First, we solve for y in the first equation:
[tex]-2y = -12.5 +4.5[/tex]
[tex]-2y=-8[/tex]
[tex]y= \frac{8}{2}[/tex]
[tex]y=4[/tex]
Then, we substitute the y value in the other equation and solve for x:
[tex]3.35x-(4)=-0.75[/tex]
[tex]3.35x=-0.75+4 [/tex]
[tex]3.35x=3.25[/tex]
[tex]x= \frac{3.25}{3.35} [/tex]
[tex]x= \frac{65}{67} [/tex]

so -2y=-12.5+4.5 thus -2y=-8 thus y=4 if y=4 than 3.35x=-.75+4 thus 3.35x=3.25 thus x=3.35/3.25

A motorboat takes 4 hours to travel 128 mi going upstream. the return trip takes 2 hours going downstream. what is the rate of the boat in still water and what is the rate of the current

Answers

First, find the MPH he was going at to go upstream which would be 128/4 or 32 mph to go upstream and twice as much to go downstream
We can now construct a system of equations where x = the speed of the both and y = the current...
Going upstream: x - y = 32
Going downstream: x + y = 64
Solve this system of equations!
x - y = 32
x = 32 + y
(32 + y) + y = 64
2y + 32 = 64
2y = 32
y = 16
Subtitute 16 for y in the first equation...
x - 16 = 32
x = 48
Rate of the boat in still water = 48mph
Rate of the current = 16 mph

Let the random variable x denote the natural numbers selected at random from one to one hundred. find the mean of x.

Answers

The answer is 50.5. Since X will consist of a random selection of the numbers from 1 to 100, the mean will be the middle of the set of numbers from 1 to 100 (so between 50 and 51). Imagine the set of whole numbers 1 to 100. To calculate the mean, we have to sum all the numbers, then divide by n=100. That gives 50,500/100= 50.5.

The students at Campbell High School have been planting trees as part of an ongoing service project. This month, they averaged 15 trees per participant. That is 150% more trees than their average the last time they did it. What was their average last time?

___ trees

Answers

I think its 0 lol, is that possible?

Final answer:

The average number of trees planted by participants last time was 10 trees, calculated by understanding the percentage increase and using basic arithmetic.

Explanation:

The average number of trees planted by participants last time was 10 trees.

To solve this, we know that the current average is 15 trees per participant, which is 150% more than the last average. This means the current average is 250% of the last average. To find the last average, you divide the current average by 2.5 (250%), giving you 6. Then, you calculate 150% of 6, which equals 9. Adding 6 and 9 together gets you 15 trees, the current average, confirming the last average was 10 trees.

concert tickets cost $15 for general admission, but only $9 with a student ID. ticket sales total $4500. wirte and graph ab equation that models this situation. explain how to use your graph to find how many student tickets were sold if 200 general admission tickets were sold 

Answers

The equation is given as 15x + 9y = 4500

The tickets sold when 200 are sold is y = 166.7

How to model the equation

The equation that models this would be

$15x + $9y = $4500

15x + 9y = 4500

If 200 admission tickets were sold we would have

15 * 200 + 9y = 4500

3000 + 9y = 4500

9y = 4500 - 3000

9y = 1500

y = 166.7 please approximate because tickets number has to be whole

The approximated total tickets that were sold is given as 167

Use your graph to check for the value of the corresponding y side if 200 tickets are sold




What is the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4) ?

y+4=−911(x−8)




y−4=−15(x+8)




y+4=−15(x−8)
plzzz helppppppp meeeeeeeeeeeeeeeeee!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Point-Slope form:
y - y1 = m (x - x1)

First, we gotta find the slope of (3, -5) and (-8, 4)
m = 4 - (-5) / -8 - 3 = 4 + 5 / -8 + (-3) = 9 / -11 = [tex] -\frac{9}{11} [/tex]

Now all we gotta do is plug one of the points into Point-Slope Form
y - 4 = [tex]- \frac{9}{11} [/tex] (x - (-8))
y - 4 = [tex]- \frac{9}{11} [/tex] (x + 8)

So the answer choice would be the first one, or A.

The equation of the line is y - 4 = (-9/11)[x + 8] which passes through the points (3, −5) and (−8, 4) option (A) is correct.

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that:

The two points are:  (3, −5) and (−8, 4)

As we know,

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

The equation of the line:

y - 4 = (4+5)/(-8-3)[x + 8]

y - 4 = (-9/11)[x + 8]

Thus, the equation of the line is y - 4 = (-9/11)[x + 8] which passes through the points (3, −5) and (−8, 4) option (A) is correct.
