Answer: choice A

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

Work Shown:

P(TV) = (number who watch tv)/(number total)
P(TV) = 30/100
P(TV) = 0.30

P(Girl) = (number of girls)/(number total)
P(Girl) = 55/100
P(Girl) = 0.55

P(TV)*P(Girl) = 0.30*0.55 = 0.165 which rounds to 0.17
We'll use this value later. So let's call this M = 0.17

Look in the "girl" row and "tv" column. The value 17 is here.
This is out of 100 people total, so
P(TV and Girl) = 17/100 = 0.17
Call this value N = 0.17

Because M = N = 0.17 approximately, this means that the two variables "TV" and "Girl" are approximately independent

So the equation P(TV and Girl) = P(TV)*P(Girl) is approximately true in this example.

This points to choice A being the answer.

The average of six numbers is 4. a seventh number is added and the new average is 5. what is the seventh number?

Answers

the average of 6 numbers is 4....
t/6 = 4.....t = 24 (the total of the 6 numbers)

(24 + x) / 7 = 5
24 + x = 35
x = 35 - 24
x = 11 <== ur 7th number

According to the question, the seventh number is 11.

Use the concept of average defined as:

Average, also known as the mean, is a statistical measure that represents the central value of a set of numbers. It is calculated by summing up all the numbers in the set and dividing the sum by the total count of numbers.

To find the seventh number,

If the average of six numbers is 4, then the total sum of those six numbers would be 6 multiplied by 4, which is 24.

Assume the seventh number is 'x'.

If the new average (after adding the seventh number) is 5, then the total sum of all seven numbers would be 7 multiplied by 5, which is 35.

To find the seventh number 'x',

Subtract the sum of the initial six numbers (24) from the sum of all seven numbers (35).

This gives us 35 - 24 = 11.

Hence,

The seventh number is 11.

True or false? in order to inscribe a circle in a triangle, the circle's center must be placed at the circumcenter of the triangle

Answers

Answer:

False.

Step-by-step explanation:

A inscribe circle in a triangle means to draw the biggest circle possible inside such triangle. To do that perfectly, we first have to find the incenter of the circle, which is the intersection of all three internal bisector of the triangle, that point is the center of the inscribed circle.

Therefore, the statement is false.

In addition, a circumcenter allow to perfectly draw a circumscribed circle, which is outside the triangle, which is not the case here.

Answers

The goal of any experiment is to test the hypothesis by adjusting the independent variables so you can see the trend of the dependent variable that you want to investigate. The independent variables are parameters that you manipulate. In this experiment, that would be the time of day. You have two independent variables: night and day. The speed of the mice is the parameter that you will measure. Once you do these set-up, you can conclude in the end the effect of the time of day on the speed of the mice.

Answers

You have to solve 3 equations pretty much simultaneously here using the x and y values in the general form of the quadratic equation [tex]y=a x^{2} +bx+c[/tex]
Start with the first values of x=0 and y=5.1 to solve for c:
[tex]5.1=a(0) ^{2} +b(0)+c[/tex] so c = 5.1
Next use the second x and y values along with the value of c in the next equation:
[tex]3.03=a(1) ^{2} +b(1)+5.1[/tex] gives you
-2.07 = a + b. Solve this for a:
a = -2.07 - b
Finally use the third set of numbers with the c value AND the subbed value for a:
[tex]1.17=a(3) ^{2} +b(3)+5.1[/tex]
1.17 = 9(-2.07 - b)+ 3b + 5.1 which simplifies to:
1.17 = -18.63 - 9b + 3b + 5.1 which further simplifies to:
14.7 = -6b and b = -2.45
Now you have c and b, let's find a using one of the simplified equations:
-2.07 = a + b
-2.07 = a - 2.45
a = .38
So here's your equation:
[tex]y=.38 x^{2} -2.45x+5.1[/tex]

The average grade mark received on 4 tests was 94. if he drops his lowest grade of 85, what will his new average be

Answers

After dropping his lowest marks of 85 the new average test mark is 97.

Given, average test score of 4 tests is 94.

Average concept:

Average = sum of all the observations / total number of observations.

Average of 4 test marks = 94

94 = Sum of all the marks obtained in 4 tests / 4

Sum of all the marks obtained in 4 tests = 94 × 4

Sum of all the marks obtained in 4 tests = 376

Now the lowest marks of 85 are removed,

Remaining sum of 3 test marks = 376 - 85

Use the properties of logarithmic functions to simplify the expression on the left side of the equation and determine the values of x and y. Then evaluate the simplified expression. The value of x is , and the value of y is. The value of the expression, rounded to nearest hundredth, is .

Answers

Final answer:

To simplify the equation using logarithmic functions, take the natural logarithm of both sides and use properties of logarithms to solve for x and y. Then substitute the values in the simplified expression to evaluate it.

Explanation:

To simplify the expression on the left side of the equation using the properties of logarithmic functions, let's work step by step:

Take the natural logarithm (ln) of both sides of the equation. The natural logarithm cancels the exponential function.The natural logarithm of 5.6/16.0 is -1.050.Now, we have the equation ln(x) - ln(2y) = -1.050.Using the property of logarithms, subtracting the logarithms of two numbers is equivalent to dividing the numbers. So we have ln(x/2y) = -1.050.To find the value of x/2y, take the inverse natural logarithm (e^) of both sides.So we have x/2y = e^(-1.050).To solve for x, multiply both sides of the equation by 2y.Therefore, x = 2y * e^(-1.050).Once you have the values for x and y, substitute them into the simplified expression to find its value.

Answer:

[tex]y=\frac{-1}{3}x+6[/tex]

Step-by-step explanation:

We have to find the equation of the line from the options given which is perpendicular to the line y=3x+2.

In order to do so we must know that , the product of the slope of the two perpendicular lines is always -1

Hence

if the slope of line A is "m" and the line B which is perpendicular to A, will have [tex]-\frac{1}{m}\\[/tex]

Also , in the slope intercept form of any equation the coefficient of x is our slope. Hence the slope of y=3x+2., is 3

Hence the slope of any line perpendicular to this will be [tex]\frac{-1}{3}[/tex]

as the product of two slopes is -1

Hence in the given options only c options has the line whose slope is [tex]\frac{-1}{3}[/tex]

b.use the theorem?

Answers

The force field seems to be

[tex]\mathbf f(x,y)=\langle2x^3+1,2y^4\rangle[/tex]

(though it's not entirely clear whether that's it...)

The parabolic path can be parameterized by

[tex]\mathbf r(t)=\langle t,t^2\rangle[/tex]

where [tex]-1\le t\le1[/tex]. Then the work done by the field along the path is

[tex]\displaystyle\int_C\mathbf f(x,y)\cdot\mathrm d\mathbf r=\int_{t=-1}^{t=1}\langle2t^3+1,2t^8\rangle\cdot\langle1,2t\rangle\,\mathrm dt[/tex]
[tex]=\displaystyle\int_{-1}^1(2t^3+1+4t^9)\,\mathrm dt[/tex]
[tex]=2[/tex]

Not sure what theorem is being referred to in part (b). Perhaps you mean the gradient theorem? In which case you would need to show that there's a scalar function [tex]f(x,y)[/tex] such that [tex]\nabla f(x,y)=\mathbf f(x,y)[/tex]. We have

[tex]\nabla f(x,y)=\left\langle\dfrac{\partial f}{\partial x},\dfrac{\partial f}{\partial y}\right\rangle=\left\langle2x^3+1,2y^4\right\rangle[/tex]

from which we have

[tex]\dfrac{\partial f}{\partial x}=2x^3+1\implies f(x,y)=\displaystyle\int(2x^3+1)\,\mathrm dx[/tex]
[tex]\implies f(x,y)=\dfrac12x^4+x+g(y)[/tex]

[tex]\implies\dfrac{\partial f}{\partial y}=g'(y)=2y^4[/tex]
[tex]\implies g(y)=\dfrac25y^5+C[/tex]

[tex]\implies f(x,y)=\dfrac12x^4+x+\dfrac25y^5+C[/tex]

We have a candidate for a potential function, so we apply the gradient theorem, which asserts that the value of the line integral is path independent and can be determined by evaluating the potential function at the endpoints of the path. We then have

[tex]\displaystyle\int_C\mathbf f(x,y)\cdot\mathrm d\mathbf r=f(1,1)-f(-1,1)[/tex]

A normal curve is ___________ about the mean. consequently, 50% of the total area under a normal distribution curve lies on the left side of the mean, and 50% lies on the right side of the mean.

Answers

In statistics, when you gather data points for the same test, you construct a distribution graph. For example, you make a statistics based on the score of a class for a 145-item test. You graph it based on frequency such as, 10 students got 50 points and so and so forth. When that test have a few outliers and have more or less the same score, you form a normal distribution graph. It is more commonly known as the Gaussian Bell Curve. An example would be shown in the picture.

A normal distribution curve is symmetric about the mean. As a result, the area under the curve on the left side of the mean would be equal to the area under the curve on the right side of the mean. So, each would constitute 50%.

Two numbers have a sum of 30 and a product of 209. what is the positive difference between them?

Answers

y + x = 30
xy = 209
y = 30 -x
x(30-x) = 209
30x - x^2 = 209
x^2 - 30x + 209 = 0
x = 19
y = 11

the difference is 19-11 = 8

The numbers are 11 and 19.

Given to us,Sum of the two numbers = 30,Product of the two numbers = 209,

Assumption

Let's assume that the first number be a and the second is b.

equation 1,

a + b = 30

equation 2,

ab = 209

Therefore, in equation 1,

[tex]a\times b = 209\\b= \dfrac{209}{a}[/tex]

substitute the value of b in equation 1,

[tex]a+b=30\\\\a+\dfrac{209}{a}=30\\\\\dfrac{a^2+209}{a} =30\\\\a^2 +209 = 30a\\a^2-30a +209 = 0[/tex]

[tex]a^2 -30a+209= 0\\a^2 -19a-11a+209= 0\\a(a-19)-11(a-19)=0\\(a-11)(a-19)=0[/tex]

Substituting the factor against 0,

[tex](a-11) = 0\\a = 11\\\\(a-19)=0\\a = 19[/tex]

Therefore, the numbers are 11 and 19.
