Solve the following
(q+9)/5 +8Q = 11 - Q

Answer:

The correct option is (a).

Step-by-step explanation:

The Pearson's correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.

Positive correlation is an association amid two variables in which both variables change in the same direction.  A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.

Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.

In this case, it is provided that the Pearson correlation coefficient is, r = +0.88.

A correlation coefficient between ±0.70 to ±1.00 are considered as strong positive correlation.

The scatter plot for correlation coefficient between +0.70 to +1.00 shows:

Thus, the correct option is (a).

Answer:

q = 27/10

Step-by-step explanation:

10/9 = 3/q

To find q, we must seperate it from the other numbers,

First we divide both sides by 3,

(10/9)/3 = (3/q)/3

10/27 = 1/q

Now we find the reciprocal of both sides to get the answer,

27/10 = q

q = 27/10

Josie ate more and burped louder because 5/8 is greater than 6/10 and Josie ate 5/8 of the pie.

Given,

Josie ate 5/8 of a pie and Marge ate 6/10 of a pie.

We need to find who ate more and therefore burped louder.

We need to compare the given fraction and see which is greater.

We have,

Josie = 5/8 of a pie.

Marge = 6/10 of a pie.

Now,

We can compare the fraction in three ways:

Case 1. - In terms of %

5/8 x 100 = 62.5 %

6/10 x 100 = 60%

62.5 % > 60%
5/8 > 6/10

Case 2. - In terms of decimals

5/8 = 0.625

6/10 = 0.6

0.625 > 0.6

5/8 > 6/10

Case 3. -In terms of multiplying

5/8 = 6/10

5 x 10 = 6 x 8

50 = 48

50 > 48

5/8 > 6/10

5/8 is greater than 6/10 so the one who eats 5/8 of the pie ate more and burped louder.

Thus Josie ate more and burped louder.

Answer:

[tex]\frac{3s^2-4}{s(s^2-4)}[/tex]

Step-by-step explanation:

Here, the question is to find the Laplace transformation of [tex]f(t)[/tex]

where, [tex]f(t)=(e^t-e^{-t})^2[/tex]

We know that for [tex]t>0[/tex],  [tex]\mathcal{L}\{f(t)\} =\int_0^{\infty} e^{-st}f(t)dt[/tex]

[tex]\mathcal{L}\{e^{at}\}=\int_0^{\infty} e^{-st}e^{at}dt[/tex]

[tex]\Rightarrow \mathcal{L}\{e^{at}\}=\int_0^{\infty} e^{(a-s)t}dt[/tex]

[tex]\Rightarrow \mathcal{L}\{e^{at}\}=\left[\frac { e^{(a-s)}}{a-s}\right]_0^{\infty}[/tex]

[tex]\Rightarrow \mathcal{L}\{e^{at}\}=\frac { 1}{s-a}\cdots(i)[/tex]

Here, we have [tex]f(t)=(e^t-e^{-t})^2[/tex]

[tex]\Rightarrow f(t)=(e^t)^2+(e^{-t})^2-2(e^t)(e^{-t})[/tex]

[tex]\Rightarrow f(t)=e^{2t}+e^{-2t}-2e^{0t}[/tex]

So, the laplace transformation of [tex]f(t)[/tex] is

[tex]\mathcal{L}\{f(t)\}=\mathcal{L}\{e^{2t}+e^{-2t}-2e^{0t}\}[/tex]

[tex]\Rightarrow \mathcal{L}\{f(t)\}=\mathcal{L}\{e^{2t}\}+\mathcal{L}\{e^{-2t}\}+\mathcal{L}\{e^{0}\}[/tex]

Now, using equation[tex](i)[/tex]

[tex]\mathcal{L}\{f(t)\}=\frac{1}{s-2}+\frac{1}{s-(-2)}+\frac{1}{s-0}[/tex]

[tex]\Rightarrow \mathcal{L}\{f(t)\}=\frac{1}{s-2}+\frac{1}{s+2}+\frac{1}{s}[/tex]

[tex]\Rightarrow \mathcal{L}\{f(t)\}=\frac{3s^2-4}{s(s^2-4)}[/tex]

Hence, the Lapelace transformation of [tex]f(t)=(e^t-e^{-t})^2[/tex] is

B) (50t)2+(60t)2 = 4002

C) 50t + 60t = 400

C) 50t2 + 60t2 = 4002

Answer:

400^2 = (50*t)^2 + (60*t)^2

Step-by-step explanation:

Given the following :

Ms. Ironperson:

moves due east

Speed = 50 mph

Rate of travel = 50t

Let time taken = t ; hence Distance covered with respect to time = ( 50 * t) = 50t

Mr. Thoro

moves due South

Speed = 60 mph

Rate of travel = 60t

Let time taken = t ; hence Distance covered with respect to time = ( 60 * t) = 50t

They are moving at right angle from each other, thus, we can apply Pythagoras rule ;

The displacement between them will be = 400 miles which is the hypotenus

From Pythagoras :

Hypotenus^2 = opposite^2 + Adjacent^2

Displacement = distance 1 + distance 2

400^2 = (50*t)^2 + (60*t)^2

Answer:

2.74 microns

Step-by-step explanation:

According to the given situation, the calculation of position, in microns, is shown below:-

Here we will use the standard normal table,

P(Z > z) = 20%

1 - P(Z < z) = 0.2

P(Z < z) = 1 - 0.2

P(Z < 0.84) = 0.8

after solving the above equation we will get

z = 0.84

Now we will use the z-score formula,

[tex]x = z \times \sigma + \mu[/tex]

[tex]x = 0.84 \times 0.35 + 2.45[/tex]

x = 0.294 + 2.45

= 2.744 microns

or

= 2.74 microns

Answer:

34

Step-by-step explanation:

To do this you would just plug in the values into the variables so you get [tex]|-5^{2} +3^{2} |[/tex] and when you simplify you get |25+9| which when you add together you get |34| and the absolute value is just 34 since it is not negative.

If m = -5 and n = 3, then the value of the expression |m² + n²| will be 34.

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

The expression is given below.

⇒ |m² + n²|

Put m = -5 and n = 3, then the value of the expression will be

⇒ |(-5)² + 3²|

⇒ |25 + 9|

⇒ |34|

⇒ 34

Answer:

0.409 mol

Step-by-step explanation:

Use ideal gas law:

PV = nRT

where P is absolute pressure,

V is volume,

n is number of moles,

R is universal gas constant,

and T is absolute temperature.

PV = nRT

(1 atm) (10.0 L) = n (0.0821 L·atm/mol/K) (25 + 273) K

n = 0.409 mol

==================================================

Explanation:

I'll use y in place of V for now. Also, I'll use x in place of t.

x = number of years

y = value of the oven

Initially, the oven's value is $875, so x = 0 and y = 875 pair up together. The point (0,875) is on the line.

The point (5, 0) is also on the line to indicate that x = 5 years later is when the value of the oven is y = 0 dollars.

We need to find the equation of the line through (0,875) and (5,0)

First we'll need the slope

m = (y2-y1)/(x2-x1)

m = (0-875)/(5-0)

m = -175

The negative slope means the oven is losing 175 dollars in value each year.

The y intercept is b = 875 as this is the initial value of the oven

Put together, y = mx+b turns into y = -175x+875

If we plugged x = 0 into this equation, we'd get y = 875

Similarly, plugging x = 5 into y = -175x+875 leads to y = 0. This helps check we have the right equation

Lastly, replace x with t and replace y with V to end up with V = -175t + 875 which is our final answer.
