If we reject the null hypothesis, can we claim to have proved that the null hypothesis is false? why or why not?

sp2606 [1]

Yes, you can claim that the null hypothesis. But you must pay attention the p-value. If the p-value is higher than the significant value the null hypothesis can't be rejected.

John bought three thermos flask at a total of st 1080 he later sold at 400 each what was his percentage

trasher [3.6K]

Answer:

$\boxed{ \bold{ \boxed{ \sf {11.11\%}}}}$

Step-by-step explanation:

Given,

Cost price of three thermos flask = 1080

Selling price of each thermos flask = 400

Finding the selling price of three thermos flask

Since, the cost of 3 thermos flask is more than that of 1 thermos flask. So, the cost of 1 thermos flask is multiplied by 3 ( i.e 400 × 3 = 1200 )

Here, the selling price is greater than cost price.

So, there is profit.

And we know that,

$\sf{profit = sp \: - \: cp}$

⇒ $\sf{1200 - 1080}$

⇒ $\sf{120}$

Profit amount = 120

Finding the profit percentage

$\sf{profit\% \: = \frac{profit}{cp} \times 100 \%}$

⇒ $\sf{ \frac{120}{1080 } \times 100\%}$

⇒ $\sf{11.11\%}$

Hope I helped!

Best regards!!

A bacteria culture begins with eight bacteria which triple in size every week. how many bacteria exist in the culture after four

bija089 [108]

Well, you would have to multiply 8 by whatever factorial of 3, in this case 4 for the number of weeks
The equation is 8 x 3^4 which equals 648

My only thing is that they only triple in SIZE, and not multiply (as in make more of themselves) so technically speaking, there would still be 8 bacteria, just much bigger

Y=mx+b is used for what math equation

soldier1979 [14.2K]

y = m x + b is a linear equation.
This equation is in the slope - intercept form, where m is the slope and b is y - intercept.
For example: y = 2 x + 5
In this equation: m = 2 ( the slope ) and b = 5 ( the line intercepts y-axis at the point ( 0, 5 ) ).
