Answer

21315

Step-by-step explanation:

If f(x) = x ⁴ - 2x ² + 3, compute the first and second derivatives:

f'(x) = 4x ³ - 4x

f''(x) = 12x ² - 4

Solve f'(x) = 0 to get the critical points of f(x) :

4x ³ - 4x = 4x (x ² - 1) = 0

→   x = -1, x = 0, x = 1

Check the sign of the second derivative at each of these points:

f'' (-1) = 8 > 0

f'' (0) = -4 < 0

f'' (1) = 8 > 0

These indicate the presence of

• two minima of f (-1) = 2 and f (1) = 2

• one maximum of f (0) = 3

which makes C the correct answer.

Answer: 70%

Step-by-step explanation:

Total number of jersey = 50.

Total number of medium sized jersey = 35

The percent of the jerseys that are medium sized jerseys will be:

= Number of medium sized / Total number of jersey × 100

= 35 / 50 × 100

= 70%

Answer: 220%

Step-by-step explanation:

165 of 75 can be written as:

165 /75

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

165 /75  ×  100 /100  = ( 165 × 100 /75 ) ×  1 /100  =  220 /100

Therefore, the answer is 220%

Answer:

mean = 2

standard deviation = 1.3

Step-by-step explanation:

For a binomial random variable X, we can use this formula for mean:

meanX = np

We use this formula for the standard deviation:

sdX = sqrt(np(1 - p))

--------------------------------------------------------------------------------------------------

Since a turn consists of rolling 12 dice, we have n = 12.

The dice are fair and 6-sided, so the probability that each die lands showing "1" is p = 1/6.

meanX = np

= (12)(1/6)

= 2 dice

sdX = sqrt(np(1 - p))

= sqrt((12)(1/6)(5/6))

≈ sqrt(1.667)

≈ 1.291 dice

The mean and standard deviation of the game of luck are;

Mean = 2

Standard deviation = 1.29

We are told that a turn consists of rolling 12 fair six sided dice.

Thus;

n = 12

Probability of each one six sided die showing 1 is;

p = 1/6

Now,the formula for the mean is;

E(X) = np

Plugging in the relevant values gives;

E(X) = 12 × 1/6

E(X) = 2

Now, for the standard deviation, we will use the formula;

Standard deviation = √(np(1 - p))

Plugging in the relevant values;

Standard deviation = √((12 × 1/6)(1 - 1/6))

Standard deviation = 1.29

Answer:

Katrina would need to buy 20 sweatshirts.

Step-by-step explanation:

The number of sweatshirts Katrina would need to order from  each company can be determined by forming the linear equation in two variables.

Given :

Let the number of sweatshirts orders from company MH Designs be 'x' and the number of sweatshirts orders from company Print Rich be 'y'.

So, the cost for ordering the sweatshirt from the company MH Design is:

[tex]21.50x = c[/tex]

Now, the cost for ordering the sweatshirt from the company Print Rich is:

18y + 70 = c'

Given that the number of sweatshirts Katrina would need to order from  each company for the costs to be the same. So :

21.5x = 18y + 70

Now, put the value of x and y so, that in the above equation, both sides become equal.

Answer:

[tex]\dfrac{1}{8}\ \text{gallons}[/tex]

Step-by-step explanation:

Amount of milk remaining is [tex]\dfrac{3}{4}\ \text{gallons}[/tex]

Number of bowls is [tex]6[/tex].

So, each bowl will contain

[tex]\dfrac{\dfrac{3}{4}}{6}[/tex]

[tex]=\dfrac{3}{4}\times \dfrac{1}{6}[/tex]

[tex]=\dfrac{3}{24}[/tex]

[tex]=\dfrac{1}{8}\ \text{gallons}[/tex]

Hence, each bowl will have [tex]\dfrac{1}{8}\ \text{gallons}[/tex] of milk.
