There is 0 probability that (a) 3 people will spend at least $150.

The probability is simply the likelihood that something will happen. When we don't know how something will turn out, we might talk about the likelihood or probability of certain outcomes.

Analysis of events that fit a probability distribution is known as biostatistics.

So, we know that:

35% of those who visit his restaurant will spend at least $150.

People visit: 6

The probability that 3 will spend at least $150:

6/100 * 35

2.1

Rounding off: 2 people are 35% of 6 people

Since 35% is only 2 people. Then it is not possible that 3 people will spend at least $150.

Then, P(E) = 0.

Step-by-step explanation:

The resultant force is  15.4 pounds while the angle is 51.3°.

We knw that the resultant force has to do with the force that would have the same effect in magnitude and direction as two or more forces that are acting together.

Using the parallelogram law of vectors;

R^2 = a^2 + b^2 - 2ab Cosθ

a = 16 pounds

b = 20 pounds

θ =  49°

R= √(16)^2 + (20)^2 - 2(16 * 20) cos 49

R =  √256 + 400 - 640cos 49

Patrice is trying a low calorie diet. She will like keep her calories consumed  between the level shown in the following compound inequality:

2450 < 2x + 50 and 2x + 50 < 3250

Let's solve for x in the inequality.

2450 < 2x + 50'

subtract 50 from both sides of the inequality

2450 - 50 < 2x + 50 - 50

2400 < 2x

divide both side by 2

2400 / 2 < x

1200 < x

2x + 50 < 3250

subtract 50 from both sides of the inequality

2x + 50 - 50 < 3250 - 50

2x < 3200

divide both sides by 2

x < 3200 / 2

x < 1600

Answer:

2x+3y=15 =15÷3=52+3=5=5-5=0

The slope of the of the equation of lines x - 2y = -1/2 and -4x - 8y = 2 are 1/2 and -1/2 respectively.

The slope intercept form is expressed as;

y = mx + b

Where m is slope and b is the y-intercept.

Given the equations in the equation;

Find the slope of the first equation.

x - 2y = -1/2

To find the slope of the line represented by the equation x - 2y = -1/2, we rewrite the equation in slope-intercept form.

x - 2y = -1/2

Multiply each term by -1

-x + 2y = 1/2

Make 2y the subject of formula

2y = x + 1/2

Divide each term by 2

y = (1/2)x + 1/4

Hence, in this form, the slope m is 1/2.

Find the slope of the second equation.

-4x - 8y = 2

Multiply each term by -1

4x + 8y = -2

Make 8y the subject of formula

8y = -4x - 2

Divide each term by 8

y = (-1/2)x - 1/4

Hence, in this form, the slope m is -1/2.

The probability that z is less than 1.13 is 0.8708.

The z score represents a value on the standard normal distribution. To find the probability of being greater or less than a certain value, we consult a z-chart or use a calculator to find the area under the probability distribution curve to the right or left of the value given.

The standard normal distribution, also known as the normal distribution or the Gaussian distribution, is a probability distribution characterized by a bell-shaped curve. It is defined by its mean (μ) being 0 and its standard deviation (σ) being 1. The probability density function (PDF) for the standard normal distribution is given by:

f(x) = (1/sqrt(2π)) * e^(-(x^2)/2)

This distribution is used in many areas of statistics and data analysis, and it is a common way to model random variables that have a large number of possible values.

The chart I have specifies values of the area to the left of the z-score that I look up. For a z-score of 1.13, my chart tells me the area to the left of (which is the probability that a value is less than) 1.13 is 0.8708.

9/5 + 7/3 = 27/15 + 35/15 = 62/15 = 4.1 cup of floor

4.1 > 3

So,they have enough flour to bake a cake that needs 3 cups of flour,

In the triangle angle 5+ angle 6 = 180, angle 2+ angle 3 = angle 4, angle 2 + angle 5 = angle 6

The exterior law of traingle states that If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles.

The exterior angles in the triangle are angle 1 , 4 and 6.

the opposite angle to 4 is angle 2 and 5, therefore angle 2+ angle 5 = angle 4

the opposite angle to angle 6 is angle 2 and 3

therefore angle 2 + angle 3 = angle 6.

The opposite angle to angle 1 is 3 and 5

The angle measure m∠HJI = 51°

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting

at a common vertex.

Given:

In the diagram below of triangle FGH,

I is the midpoint of HF,

and J is the midpoint of HG.

That means, JI is parallel to GF

And the angle measure:

m∠HGF = 67−8x

m∠HJI = 2x+47

So,

m∠HGF =  m∠HJI

67−8x = 2x+47

8x + 2x = 67 - 47

10x = 20

x = 2

So, m∠HJI = 2(2)+ 47

= 51°

Therefore, m∠HJI = 51°

The new image would be smaller in sample size than the original image.

For example, if the scale factor is 0.5, the new image will be half the size of the original image. To determine the exact size of the new image, the scale factor is multiplied with the width and height of the original image. For example, if the original image is 200 x 100 pixels, and the scale factor is 0.5, the new image will be

(200 x 0.5) = 100 x (100 x 0.5)

= 50 pixels.

The same concept applies when the scale factor is a decimal. For example, if the scale factor is 0.75, the new image will be three-quarters the size of the original image. In this case, the new image would be

(200 x 0.75) = 150 x (100 x 0.75)

= 75 pixels.

In summary, when the scale factor is less than 1, the new image will always be smaller than the original image, depending on the scale factor. The exact size of the new image can be determined by multiplying the width and height of the original image with the scale factor.

Solution of the initial-value problem. y″ + 4y′ + 6y = 0 , y(0) = 2 , y′(0) = 4 is

y(x) = 4√2e⁻²ˣsin⁡(2x) + 2 e²ˣcos⁡(2x)

The Initial Value Problem in Calculus: We have a second order differential equation with initial condition and we need to compute the general solution. If we are not able to make factor this quadratic equation, so we'll apply the quadratic formula. For an quadrtic equation

an² + bn+ c = 0 ----------(1)

the solution is n = (-b ±√b² - 4ac)/2a.

Now, the equation is y″+4y′+6y=0,

and y(0)= 2, y'(0) = 4

The auxiliary equation becomes,

n² + 4n+ 6 = 0,

As we see not possible to make factor in this quadratic equation, so we'll apply the quadratic formula, a = 1 , b = 4 , c = 6

=> n = ( - 4 ±√16 - 24 )/2

=> n =( - 4 ± √-8)/2

=> n = (-4 ± 2√2i )/2 = 2( - 2 ± √2i)/2

=> n = -2 ± √2

Hence the roots are n = -2 ± √2i

So, general solution will be written in the form:

y(x) = Ae⁻²ˣsin⁡(√2x) + Be⁻²ˣ cos⁡(√2x), where A, B are arbitrary constants. By initial conditions,

y(0)= , Ae⁻⁰sin⁡(√2×0) + Be⁻⁰cos⁡(√2× 0) = 2

=> B = 2 ----(*)

differentiating the general solution equation with respect to x, we get

y′(x) = −2A e⁻²ˣ sin⁡(2x) + √2A e⁻²ˣ cos⁡(2x) − 2Be⁻²ˣ cos⁡(2x) − √2Be⁻²ˣ sin⁡(−2x)

since, y'(0) = 4 , −2A e⁻⁰ sin⁡(0) + √2A e⁻⁰ cos⁡(0) − 2B e⁻⁰ cos⁡(0) − √2B e⁻⁰ sin⁡(0) =4

=> √2A + 2B = 4 and using (*),

A = 2- B = 4√2
