H + B x 100 = 1560

H + 100B = 1560

100B = 1560 - H

B = 1560 - H/100

H + B x 100 = 1560

H + 100B = 1560

H = 1560 - 100B

Ciara, an ornithologist, has 444 bird feeders at separate locations. She wonders if birds are equally likely to visit each of th
dybincka [34]

The expected count of visits is the mean or average visits to each feeder

The expected count of visits to the third feeder is 87.5

<h3>How to determine the expected count of visit?</h3>

The table of values is given as:

Feeder                 1   2    3   4

Observed visits 80 90 92 88

In this case, the null hypothesis implies that the visits to each feeder are uniformly distributed

So, the expected count is calculated using:

Expected count =Visits/Feeders

This gives

Expected count = 350/4

Evaluate the quotient

Expected count = 87.50

Hence, the expected count of visits to the third feeder is 87.5

How many different arrangements of 5 letters can be made from the 26 letters of the alphabet?
VikaD [51]
Answer: P(26,5).

That is all the possible combinations of 5 letters made out from 26 letters.

That is 26! / [ 5! ( 26 - 5)! ] = 26! / [5! 21! ] = 26*25*24*23*22*21! / [ 5! 21!] =

= 26*25*24*23*22 / [5*4*3*2*1] = 65,780 arrangements.

Stels [109]

Answer:

<h2>124.51%</h2>

Step-by-step explanation:  

In this problem, we are expected to solve for the percentage change, given the opening  point and the closing point

given that the low is 4014

and the high is  9012

the formula to calculate the percentage change is given as

%change= (high-low)/low*100

substituting our given data we have

%change= (9012-4014)/4014*100

%change= (4998)/4014*100

%change= (1.2451)*100

%change= 124.51%

The total change in the stock market from the beginning of the day to the end of the day is 124.51%
