Two cities on a map is 7.5 centimeters.The map is 1 centimeter represents 30 kilometers.What is the distance between the cities in kilometers?

Answer:

9/11

Step-by-step explanation:

To divide, you have to flip the dividend.

So, 4/9 would become 9/4

Then you multiply 4/11 by 9/4

This would give you 36/44

Answer:

tom ate sandwiches of cucumber and also had tea

Step-by-step explanation:

The computation is shown below:

P:I = popcorn

Q:I  = raisins

R:I = cucumber sandwiches

S:I = sodas

T:I = tea

1. It could be either popcorn or raisins

2. If i take sandwiches of cucumber so it also had soda

3. Do not drink soda or tea

Now considered the negation of 1, 2 and 3

So,

[tex]\sim (PVQ) = \sim P \wedge \sim Q\\\\\sim (R \to S) = \sim(\sim R\vee S) = R \wedge \sim S\\\\ \sim(\sim S \vee \sim T) = S \wedge T[/tex]

Now combining 4, 5 and 6

We get

[tex]\sim P \wedge \sim Q \wedge R \wedge \sim S \wedge S \wedge T\\\\\sim P \wedge \sim Q \wedge R \wedge T[/tex]

So, tom ate sandwiches of cucumber and also had tea

Answer:

The probability is    [tex]P(C | I) =  0.025[/tex]    

Step-by-step explanation:

From the question we are told that

      The  proportion analyzed by  Amir is  P(A) =  0.55

      The proportion analyzed by  Betty is  P(B)  =  0.30

     The  proportion analyzed by  Carlos is  P(C) =  0.15

     The inaccuracy by  Amir  is   p = 0.6% =  0.006

     The inaccuracy by  Betty  is  b = 0.4% = 0.004

    The inaccuracy by  Carlos  is c = 0.1% =  0.001

Generally the probability of inaccurate analysis is mathematically represented as

     [tex]P(I) =  P(A) *  p  +  P(B) *  b  +  P(C) *  c[/tex]

=>  [tex]P(I) =  0.55 * 0.006  +  0.30  *  0.004  +  0.15  *  0.001 [/tex]

=>  [tex]P(I) =  0.006 [/tex]

Generally the probability that an inaccurate analysis, detected at final verification, was conducted by Carlos is mathematically represented as

       [tex]P(C | I ) =  \frac{P(C) *  c}{P(I)}[/tex]

=>     [tex]P(C | I) =  \frac{   0.15  *  0.001}{ 0.006}[/tex]

=>     [tex]P(C | I) =  0.025[/tex]

Answer:

The equation is: y + -3 = 8

And y = -5

Step-by-step explanation:

Sum means addition which means the sum of a number y and -3 is the same as y + -3. So, you would add the =8's to make it an equation.

Answer:

y = 2x - 6

Step-by-step explanation:

Use the slope-intercept form of the equation of a line.

y = mx + b

y = 2x + b

4 = 2(5) + b

4 = 10 + b

b = -6

y = 2x - 6

Answer:

The answer in the expanded form is (0.9 + 0.07 + 0.007) millimeters

Step-by-step explanation:

Here, we want to write the size of the diameter of the sediment in the expanded form without exponents

Thus, we have;

0.977 = 0.9 + 0.07 + 0.007

The size of Anna's sample in expanded form can be written be expanding the decimal places.

The expanded form without exponents is (0.9 + 0.07 + 0.007).

Given:

The given diameter is 0.977 millimeters.

Separate the two decimal place of given number.

[tex]0.977=0.9+0.077[/tex]

Separate the three decimal place of given number.

[tex]0.977=0.9+0.07+0.007[/tex]

The expanded form without exponents is (0.9 + 0.07 + 0.007).

Given that:

Speed of light = 3 * 10^8 m/s

Distance of sun to Mars = 230,000,000 meters

How many seconds does it take for sunlight to reach Mars?

Using the relation :

Speed = distance / time

Hence ;

Time = Distance / Speed

Time = 2.3 * 10^8 / 3 * 10^8

Time = 0.766

Time = 0.8 ( nearest tenth)

Question asked:Jacob and Sarah are saving money to go on a trip. They need at least $1975 in order to go. Jacob mows lawns and Sarah walks dogs to raise money. Jacob charges $25 each time he mows a lawn and Sarah charges $15 each time she walks a dog. The number of dog walks that Sarah has scheduled is no more than four times the number of lawns Jacob has scheduled to mow. Sarah will walk at least 50 dogs.Write a set of constraints to model the problem, with x representing the number of lawns mowed and y representing the number of dogs walked.

My answer:

They need at least $1975. Jacob charges $25 each time he mows a lawn and Sarah charges $15 each time she walks a dog.

25x + 15y ≥ 1975

The number of dog walks that Sarah has scheduled is no more than four times the number of lawns Jacob has scheduled to mow.

y ≤ 4x

Sarah will walk at least 50 dogs.

y ≥ 50

Answer:

5/6

Step-by-step explanation:

First, you need to make sure they have a common denominator, or else addition is not possible.

Luckily, in this case, 6 and 3 are divisible.

You would multiply 2 by 2/3 to get the common denominator of 6

The new expression would be:

4/6 + 1/6

Now, you just need to add the numerators

4 + 1 = 5

The correct answer would be 5/6.

Hope this helps! Good luck :)

Answer:

Response Bias

Step-by-step explanation:

This is an example of the problem known as Response Bias. This is basically any and all reasons an individual may have for not answering a question truthfully regardless of the reason. This is a huge problem when conducting a survey since there are almost no ways to prevent this and false responses can completely contaminate the results gathered by the survey. In this scenario, the reason for lying was fear and shame which are normal emotions for individuals and is impossible to predict who will lie due because of it.

Answer:

She will be paid $1,350

Step-by-step explanation:

Linear Modeling

Some events can be modeled as linear functions. If we are in a situation where a linear model is suitable, then we need two sample points to make the model and predict unknown behaviors.

The linear function can be expressed in the slope-intercept format:

y=mx+b, where m and b are constants.

The payments for a salesperson will be linearly modeled. There are two known points: When the sales were $16,000, the payment was $1,600. This makes the point (16,000;1,600).

We also know when the sales were $12,000, the payment was $1,400. The point is (12,000;1,400)

Let's use the points to find the values of m and b.

Using (16,000;1,600):

1,600=m*16,000+b

Using (12,000;1,400):

1,400=m*12,000+b

Subtracting both equations:

200=16,000m-12,000m

200=4,000m

Solving:

m=200/4,000=0.05

Using the first equation and the value of m:

1,600=0.05*16,000+b

1,600=800+b

Solving:

b=800

The equation is now complete:

y=0.05x+800

She sold $11,000 this month, so the payment is:

[tex]y=0.05\cdot 11,000+800[/tex]

Y=550+800=1,350

She will be paid $1,350

Answer:

1350

Step-by-step explanation:

(Note: this method is not the best to use in future problems, please refer to the other answer if you want something better to use.)

16,000-12,000=4,000

1,600-1,400=200

To find the rate of change in 1000s:

200/4 = 50

Essentially this means the rise is 50 and the run is 1000, so, just remove $50 from the payment from 2 months ago to find your answer

Answer:

Scale factor=2

The perimeter of the enlarged figure is 19

The area of the enlarged figure is 4 times the area of the original figure

Step-by-step explanation:

Scaling

There are two figures, the red rectangle (original) and the blue rectangle (enlarged).

To find the scale factor we directly compare the height of both rectangles and note:

height of original rectangle=1.5

height of enlarged rectangle=3

Thus, the scale factor is 3/1.5 = 2

Scale factor=2

The original perimeter is calculated as:

P1=2*1.5+2*3.25=3+6.5=9.5

The perimeter of the enlarged figure is 2 times the original perimeter

P2=2*9.5=19

The perimeter of the enlarged figure is 19

To calculate the area of the enlarged figure, we use

A2=H2*W2

Where H2 and W2 are the height and width of the enlarged figure.

Since

H2=2*H1

W2=2*W1

A2=4*A1

The area of the enlarged figure is 4 times the area of the original figure

Answer:

$ 37.32 is the required budget in dollars (2 decimals) to have the cheese burgers in your sample

Step-by-step explanation:

Here

Z∝ =1.64

Standard Deviation=S= 0.21

Sampling Error= SE= 0.05

As Sampling Error is found by

SE= z * s/√n

√n= z*s/ SE

n= (z* s/ SE)²

We use the above formula  to calculate N

N= ( Z * S/SE)²

N= (1.64 * 0.21/0.05)²

N= 28.9296= 28.93

Cost of N number of burgers

= Cost *N

= $1.29 * 28.93= $ 37.32 is the required budget in dollars (2 decimals) to have the cheese burgers in your sample
