Answer: The percentage of students signed up for neither canoeing nor trekking m=32%

Step-by-step explanation:

Given: The total number of students in summer camp n(S)=120

Number of students signed up for canoeing n(C)=72

Number of students signed up for trekking m(T)= 23

Number students signed up for trekking and canoeing n(C∩T)=13

Number of students signed up for only canoeing (Not trekking)=72-13=59

Number of students signed up for only trekking (Not canoeing)=23-13=10

Now, the number of students signed up for either trekking or canoeing is given by :-

n(C\cup T)=n(S)+n(C)-n(C\cap T)\\\\\Rightarrow n(C\cup T)=72+23-13=82

Number of students signed up for neither trekking nor canoeing is given by :-(n(C\cup T))'=n(S)-n(C\cup T)=120-82=38

The percentage of students signed up for neither canoeing nor trekking

=\frac{38}{120}\times100=31.6666666667\approx32\%

Answer:

Step-by-step explanation:

y = -x + 3

y + 1 = -(x + 1)

y + 1 = -x - 1

y = -x - 2

x + y + 2 = 0 is the solution

An educational psychologist wishes to know the mean number of words a third grader can read per minute. She wants to make an est
nirvana33 [79]

Answer:

The 80% confidence interval for the mean number of words a third grader can read per minute is between 40.4 wpm and 40.8 wpm.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.8}{2} = 0.1

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.1 = 0.99, so z = 1.28

Now, find M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.28*\frac{4.1}{\sqrt{840}} = 0.2

The lower end of the interval is the sample mean subtracted by M. So it is 40.6 - 0.2 = 40.4 words per minute.

The upper end of the interval is the sample mean added to M. So it is 40.6 + 0.2 = 40.8 words per minute.

The 80% confidence interval for the mean number of words a third grader can read per minute is between 40.4 wpm and 40.8 wpm.

How many 5-digit palindromes contain only even digits?
34kurt

Answer:

The correct answer is - 900

Step-by-step explanation:

A palindrome is a positive integer that is same whether read from left to right or from right to left. For example, 123321 palindromes.

An n-digit palindrome is determined from the first  n/2  digits if n is even, and from the first n+1/2 digits if n is odd.

Therefore, if  n  is even, there are  9×10⁽n⁻²/²⁾  palindromes; and if n is odd, there are  9×10⁽n₋²/²⁾ palindromes.  where n is number of digits.

For  n=5 , there are  9×10²=900 palindromes

Lia wants to estimate 4 1/7 x 3 3/5 To estimate, she simplifies the expression 4 x 3 1/2 .
Temka [501]
Given:
4 1/7 * 3 3/5

4 1/7 = (4*7)+1/7 = 29/7
3 3/5 = (3*5)+3/5 = 18/5

29/7 * 18/5 = 29 * 18 / 7 * 5 = 522 / 35 = 14.91

Simplified expression.
4 x 3 1/2

3 1/2 = (3*2)+1/2 = 7/2

4 * 7/2 = 4*7 / 2 = 28 / 2 = 14

It is a close estimate.   Actual: 14.91 vs Estimate: 14
