For dimensions of x =10 and y=5 for the base and height that will make the tank weight as little as possible.

Here we are given the information of a square-based, open-top, rectangular steel holding tank, so here the tank is in the shape of a cuboid and we know  the formula  for :

volume = x*y*z, as  here it is a square base, so the volume will be

volume =  x²*y, where x and y are the dimension of the base and height

So for the  given reason,  

=>x²*y =  500

=> y = 500/x²

Again, the surface area formula  will be

S=x²+4xy, substituting the value of  y in this question

=>S=x²+4x(500/x²)

=>S=x²+2000/x

Differentiating the above formula with respect to x, we get

=>2x-2000/x²=0

=>2x³= 2000

=>x³= 1000

=>x =10

so the substituting the x values of x in  the equation y , we get

y = 500/x²

=>y = 5

so the dimensions are x= 10 and y=5

The margin of error for the confidence interval (6.5, 6.9) is 0.2 , the correct option is (c) .

In the question ,

it is given that ,

the 95% confidence interval for mean hours slept in the graduate students is (6.5, 6.9) ,

we have to find the margin of error ,

we know that the formula for the margin of error is

= (upper limit of confidence interval - lower limit )/2

From the given interval ,

we see that ,

upper limit of confidence interval = 6.9

lower limit of confidence interval = 6.5

Substituting the above value in margin of error formula ,

we get ,

margin of error = (6.9 - 6.5)/2

= 0.4/2

= 0.2

Therefore , the margin of error is 0.2   .

AS per the permutation concept, the number of ways can Alice win or draw exactly three times is 240

Permutation:

In probability, permutation refers the arrangement of objects in a definite order.

Given,

Alice and Bob are playing a game in which there are several rounds and each round can be a win, a loss, or a draw for Alice.

Here we need to find the number of ways can Alice win or draw exactly three times, if they play 6 rounds.

While we looking into the given question, we know that,

Total number of games = 6

Possible values = 3 ( win, loss, or draw)

Here we need to find the probability of winning 3 times, it can be calculated by using the permutation as,

=> 6! / (6 - 3)!

=> 6! / 3!

=> 120

Similarly, the the probability of draw 3 times, it can be calculated by using the permutation as,

=> 6!/ (6 - 3)!

=> 120

So, the number of ways can Alice win or draw exactly three times is

=> 120 + 120 =  240

Answer:

None of the Above?

Step-by-step explanation:

1.) If we put this into words, we would get -5y+7/3y=-5-8/3y-4

2.) By moving all y terms to one side, we get -5y + 7/3y + 8/3y = -5 - 4

3.) By simplifying, you would get -4 2/3y = -9.
4.) If you divide both sides by -4 2/3, you would get that y = -9 * - 3/14 = 27/14

The final value of the product = 292

According to the given equation -

= (4a2+3b)x(4a2+36)

multiply the whole equation-

= 16a4+144+12a2b+108

as we can see that the values of a and b are given 1 and 2 respectively,

so putting the values of a and b in the equation we get -

The intervals on which the function f(x) = ax² + bx + c (where "a" doesn't = 0) is increasing and decreasing is x>-b/2a and x<-b/2a

Given that,

We have to find the intervals on which the function f(x) = ax² + bx + c (where "a" doesn't = 0) is increasing and decreasing.

We know that,

Take the function equation,

f(x)=ax² + bx + c

The derivative of the function of x is  

f'(x)=ax+b

So, f(x) is increasing when f'(x) > 0

f(x) is decreasing when f'(x) < 0

Then we can say

f'(x) > 0 , when  b > 0  and a < 0

2ax + b < 0

2ax < - b

x<-b/2a

Now,

f'(x) < 0 , when  b < 0  and a > 0

2ax + b > 0

2ax > - b

x>-b/2a
