A car breaks from a speed of 108km/h to 72km/h during a displacement of 100m, what is its aceleration ?​

Answers

Answer 1

First, note that 100 m = 0.100 km.

Recall that

v² - u² = 2 ax

where u and v are initial and final velocities; a is acceleration; and ∆x is displacement. Solve for a :

(72 km/h)² - (108 km/h)² = 2 a (0.100 km)

a = ((72 km/h)² - (108 km/h)²) / (0.200 km)

a = -32,400 km/h²

If you want to convert this to m/s², we have

(-32,400 km/h²) = (-32,400 km/h²) (1000 m/km) (1/3600 h/s)²

(-32,400 km/h²) = -2.50 m/s²

A salesperson is paid a flat rate plus a fixed percentage of her sales. Last month, she sold $16,000 worth of goods and was paid $1,600. Two months ago, she had $12,000 in sales and was paid $1,400. This month she sold $11,000 worth of goods. How much will she be paid?​

Answers

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

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

QUESTION 05 (10 points) - Sample Size Determination in Estimating Population Mean In this hypothetical scenario, you are working for a consumer protection agency. Your boss assigned you the task of conducting a survey on cheese burgers at a national restaurant chain. In your report, you would need to construct a 90% confidence interval for the mean weight of cheese burgers. Based on past surveys on cheese burgers at this restaurant chain, the standard deviation of weight is 0.21 pound. It is required that the maximum likely sampling error of mean weight be 0.05 pound. A cheese burger at the restaurant chain costs $1.29. What is the required budget in dollars (2 decimals) to have the cheese burgers in your sample, assuming no sales tax

Answers

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

Step-by-step explanation:

The computation is shown below:

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

So, tom ate sandwiches of cucumber and also had tea

In a laboratory, 3 technicians are analyzing the active ingredient in the product vials. Amir, Betty, and Carlos analyze 0.55, 0.30, and 0.15 of the vials, respectively. Inaccurate are 0.6 percent of the analyses conducted by Amir, 0.4 percent of the analyses conducted by Betty, and 1.0 percent of the analyses conducted by Carlos in this study. What is the probability that an inaccurate analysis, detected at final verification, was conducted by Carlos

Answers

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]
