A woman has some cats and birds. together the animals have 10 heads and 26 legs. how many cats and birds does she have?
Tanzania [10]
Total heads = 10
Total legs = 26
Cat = 4 legs
Birds = 2 legs

------------------------------------
Assumed all birds :
------------------------------------
Total legs = 10 x 2 = 20

------------------------------------
Difference in legs :
------------------------------------
26 - 20 = 6

------------------------------------
Difference in legs between the two animals:
------------------------------------
4 - 2 = 2

------------------------------------
Find number of cats :
------------------------------------
6 ÷ 2 = 3

------------------------------------
Find number of birds :
------------------------------------
10 - 3 = 7

------------------------------------------------------------------------
Answer: There are 3 cats and 7 birds.

"Conservationists have despaired over destruction of tropical rain forest by logging, clearing, and burning." These words begin
krok68 [10]

Answer:

The answer is "(0.461 , 7.206)"

Step-by-step explanation:

In the given question some information is missing, that is data. so, the correct answer to this question can be defined as follows:

UnLogged:

x_1=17.500\\s_1=3.529\\n_1=12

Logged:

x_2=13.667\\ s_2=4.500\\n_2=9\\

formula of std error:

\ std \ error =\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}

                =\sqrt{\frac{3.529^2}{12}+\frac{4.500^2}{9}}\\\\=\sqrt{\frac{3.529^2\times 3+4.500^2\times 4}{36}}\\\\=1.8133

Point differential estimation =x_1-x _2

                                              = 17.500-13.667\\=3.833

For 90 percent t= 1.860 Cl & 8 df  

error of margin E = t\times \ std \ error

                             = 1.860 \times 1.8133\\= 3.373

Lower bound =mean difference -E=0.461

Upper bound = mean difference+ E=7.206

In the above 90% confidence interval were the population mean= (0.461 , 7.206)
