X-y=. 2-3=-1

x(y)=. 2(3)=6

x+y= 2+3= 5

x/y= 2/3= 0.66......

Therefore, x-y has the smallest value, that is -1.

Answer:

  x - y = -1

Step-by-step explanation:

The value of the first expression is negative:

  2 - 3 = -1

All of the other expressions give positive values, so are larger.

The expression with the smallest value is x-y.

_____

If x(y) is supposed to mean x^y, the exponentiation operator is needed. Otherwise, it is interpreted as x·y.

∫x(x-6)³dx by using substitution u=x-6​
Agata [3.3K]

Answer:

\large\boxed{\int\bigg(x(x-6)^3\bigg)dx=\dfrac{1}{5}(x-6)^5+\dfrac{3}{2}(x-6)^4+C}

Step-by-step explanation:

\int\bigg(x(x-6)^3\bigg)dx\Rightarrow\left[\begin{array}{ccc}x-6=u\\x=u+6\\dx=du\end{array}\right]\Rightarrow\int\bigg((u+6)u^3\bigg)du\\\\=\int(u^4+6u^3)du=\dfrac{1}{5}u^5+\dfrac{6}{4}u^4+C=\dfrac{1}{5}(x-6)^5+\dfrac{3}{2}(x-6)^4+C

What is the answer to this question? Write an expression in simplest form for the perimeter of a right triangle with leg lengths
blagie [28]

Answer:

Step-by-step explanation:

Since the length of both legs of the right angle triangle are given, we would determine the hypotenuse, h by applying Pythagoras theorem which is expressed as

Hypotenuse² = one leg² + other leg²

Therefore,

h² = (3a)³ + (4a)³

h² = 27a³ + 64a³

h² = 91a³

Taking square root of both sides,

h = √91a³

The formula for determining the perimeter of a triangle is expressed as

Perimeter = a + b + c

a, b and c are the side length of the triangle. Therefore, the expression for the perimeter of the right angle triangle is

√91a³ + (3a)³ + (4a)³

= √91a³ + 91a³

Interpret the regression coefficients. Fill in the blanks below.
bearhunter [10]

Answer:

With the information given in the question, the blank spaces are filled thus:

Step-by-step explanation:

1. The <u>intercept </u>is the estimated amount of a purchase, if time spent viewing the online catalog was zero minutes.

2. The <u>slope coefficient</u> is the estimate of amount that a purchase charges/changes, for one extra minute spent viewing the online catalog.

3. The <u>proportion</u> of total variation in purchases that can be explained by variation in the minutes spent viewing an online catalog is equal to the <u>coefficient of determination</u>.

4. The p-value is the <u>probability value</u>

5. <u>Reject</u> the null hypothesis if there is <u>sufficient </u>evidence to support the claim that the regression slope coefficient is not equal to zero.

NOTE: In the case of number 5, the assumption is that;

Null Hypothesis: The regression slope coefficient = 0

Alternative Hypothesis: The regression slope coefficient ≠ 0

Other answers require numerical information and full data, in order to be computed or calculated.

50 people are selected randomly from a certain population and it is found that 12 people in the sample are over 6 feet tall. wha
Taya2010 [7]

Answer:

The point estimate of the proportion of people over 6ft to total people is 6:25

Step-by-step explanation:

To find this, simply start with the number of people over 6 ft and total people as a proportion.

12:50

Then simplify by dividing by 2

6:25
