Answer:

Option (2)

Step-by-step explanation:

Option (1).

Time taken by Tina to walk = 56 minutes

Time taken by her sister to walk the same distance = x minutes

If both the sisters take the same time to walk, then

x = 56 minutes

Option (2).

Let the height of Tina = x inches

and the height of her brother = 56 inches

if Tina is shorter than her brother then,

x < 56 inches

Option (3).

Tina's dog weighed two months ago = 56 pounds

If the dog gained the weight in two months then weight before 2 months will be less than the present weight.

Let the weight of her dog is x pounds now,

x > 56 pounds

Option (4).

Amount with Tina = $x

Cost of the camera = $56

If the money with Tina has enough money to buy the camera, then the amount of money with her will be higher than the cost of the camera.

x > $56

Option (2) will be the answer.

Answer:

About 36.87

Step-by-step explanation:

The sine of an angle in a right triangle is the length of the opposite side divided by the length of a hypotenuse, which in this case is 3/5. Therefore, the measure of the angle is the arcsin of 3/5 or about 36.87 degrees. Hope this helps!

What is the gradient of a function in a vector field?

The gradient of a function is related to a vector field and it is derived by using the vector operator ∇ to the scalar function f(x, y, z).

Given vector field:

F = ( -2x, y, - 2 z )

[tex]\mathbf{\nabla \cdot F = ( i \dfrac{\partial }{\partial x }+ j \dfrac{\partial}{\partial y} + k \dfrac{\partial}{\partial z}) \langle -2x, y, -2z \rangle}[/tex]

[tex]\mathbf{ \nabla \cdot F = ( \dfrac{\partial }{\partial x }(-2x)+ \dfrac{\partial}{\partial y}(y) + \dfrac{\partial}{\partial z}(-2z))}[/tex]

= -2 + 1 -2

= -3

According to divergence theorem;

Flux [tex]\mathbf{=\iiint _v \nabla \cdot (F) \ dv}[/tex]

x+y+z = 2; [tex]1^{st}[/tex]  Octant

[tex]=- \dfrac{3}{2}(8-8+\dfrac{8}{3})[/tex]

Answer:

Average income for the remaining 8 months = $2,111.25

Step-by-step explanation:

Given:

Average income of 4 months = $1,420.25

Annual average income = $1,780.75

Find:

Average income of 8 months

Computation:

⇒ Annual average income = [Average income of 4 months + Average income of 8 months] / 2

⇒ $1,780.75 = [$1,420.25 + Average income of 8 months] / 2

⇒ $3,561.5 = $1,420.25 + Average income of 8 months

⇒ Average income of 8 months = $3,561.5 - $1,420.25

Average income of 8 months = $2,111.25

Answer:

The rate of change of the Coyote population in 2002 is 32

Step-by-step explanation:

Given the formula for the population of a Coyotes in the Northwestern portion of Alabama, we are to calculate rate of change of the Coyote population in the year 2002 where t = 2

The formula is given as;

P(t) = (t^2 + 100) ln (t + 2)

The rate of change refers to the first integral of the formula;

Thus we need to calculate this by the use of product formula;

The first differential of t^2 + 100 is 2t

while that of ln(t + 2) is 1/(t + 2)

P’(t) = 2t(ln (t+2)) + (t^2 + 100) (1/t+2)

Now, we substitute 2 for the value of t here.

P’(2) = 2(2)( ln (2 + 2) + (2^2 + 100)(1/(2+2))

P’(2) = 4 ln 4 + 104(1/4)

P’(2) = 4ln 4 + 26

P’(2) = 5.55 + 26 = 31.55 which is approximately 32

Step-by-step explanation:

The difference between a rational number and an irrational number is always an irrational number. The correct option is B.

A Rational Number is a number of the form p/q, p & q are integers, and q ≠ 0.  An irrational number is all real numbers except rational numbers i.e. it is a non-repeating and non-terminating decimal number or it can not be expressed in a ratio of two integers.

Further, natural numbers can be rational numbers. Also, all repeating and terminating decimals are rational.

The difference between a rational number and an irrational number is always an irrational number. For example:

2 - √3 is always an irrational number where 2 is rational and √3 is an irrational number.

Hence addition and subtraction of rational and irrational numbers is always an irrational number.

The degrees of freedom are

And the p value for this case is:

[tex]p_v =2*P(t_{(6)}>1.512)=0.181[/tex]  

The p value is a higher value and using a significance levels of 5% or 10% we see that the p value is higher than the significance level and then we FAIL to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is different from 7 ounces.

Step-by-step explanation:

Information provided

[tex]\bar X=7.4[/tex] represent the sample mean

[tex]s=0.7[/tex] represent the sample standard deviation

[tex]n=7[/tex] sample size  

[tex]\mu_o 7[/tex] represent the value to verify

System of hypothesis

We want to verify if the average amount of coffee per cup is different from 7 ounces, the system of hypothesis would be:

Answer:

  75% reduction

Step-by-step explanation:

The price dropped by $120. As a percentage of the original price, that is ...

  -$120/$160 × 100% = -75%

The price changed by -75%.

Answer:

75% decrease.

Step-by-step explanation:

The original price is $160 and we went to $40.

That means the price got reduced by $120 in the process.

$120/$160 = 0.75 = 75%.

So in other words, we lost 75% of the price ($120) and got left with 25% of the price ($40).
