Help, Please! I really need this done right Carlos is analyzing the results of an experiment on two groups of mice in which he c

ompared the difference in their weight gain after feeding each group a different type of food for one month. The difference in the mean weight gain is 0.6 grams. The standard deviation of the difference in sample means is 0.305. The 68% confidence interval for the population mean difference is ±(A.0.305, B.0.600, C.0905 D.1.200) The 95% confidence interval for the population mean difference is ±(A.0.160,B.0.305,C.0.610,D.0.915)

Given:
difference in the mean weight gain is 0.60 grams
standard deviation of the difference in sample mean is 0.305

68% confidence interval for the population mean difference is a) 0.305

0.60 <u>+</u> 1 * 0.305
0.60 + 0.305 = 0.905
0.60 - 0.305 = 0.295

95% confidence interval for the population mean difference is c) 0.61

0.60 <u>+</u> 2 * 0.305
0.60 + 0.61 = 1.21
0.60 - 0.61 = -0.01

Some members of the cooking club are making cakes which they will sell at a street fair for $10 apiece. It costs $10 for a booth
Alika [10]

Answer:

The cooking club sales covers the expenditure when 2 piece of cakes are sold.

Step-by-step explanation:

Given:

Selling price of each piece of cake = $10

Cost for booth at fair = $10

Ingredients for each piece of cake = $5

We need to find the number of pieces of cake sold when the sales cover the expenditures.

Solution:

Let the number of pieces be 'x'

So We can say that the point at which the sales cover the expenditures can be calculated as Selling price of each piece of cake multiplied by number of pieces will be equal to Cost for booth at fair plus Ingredients for each piece of cake multiplied number of piece of cakes.

framing in equation form we get;

10x =10+5x

Now Subtracting both side by '5x' using Subtraction property we get;

10-5x=10+5x-5x\\\\5x=10

Now Dividing both side by 5 we get;

\frac{5x}{5}=\frac{10}{5}\\\\x=2

Hence The cooking club sales covers the expenditure when 2 piece of cakes are sold.

\displaystyle\\&#10; -3\tan^2x + 1 = 0\\\\&#10; -3\tan^2x = -1\\\\&#10;\tan^2x =  \frac{-1}{-3} \\\\&#10;\tan^2x =  \frac{1}{3} ~~~~~ \Big|~\sqrt{~~~} \\\\&#10;\sqrt{\tan^2x} =  \sqrt{\frac{1}{3}} \\\\&#10;\tan x = \Big| \frac{1}{ \sqrt{3} } \Big|\\\\&#10;\tan x = \Big| \frac{\sqrt{3}}{ 3 } \Big|\\\\&#10;\tan x =  \frac{\sqrt{3}}{ 3 }~~~\Longrightarrow~~x_1=  \frac{\pi}{6} + k\pi,~~k \in N \\\\  &#10;\tan x =  -\frac{\sqrt{3}}{ 3 }~~~\Longrightarrow~~x_2=  \pi-\frac{\pi}{6} + k\pi = \frac{5\pi}{6} + k\pi,~~k \in N \\\\  &#10;
