Tami rolled a die 20 times. 14 times it landed on an even number; 6 times it landed on an odd number. How does the experimental and theoretical probability compare, for rolling an odd number?
A)
The theoretical probability is higher.
B)
The experimental probability is higher.
C)
The experimental and theoretical probability are equal.

Answers

Answer 1

The answer is the Theoretical probability is higher than the Experimental probability.

Experimental and Theoretical Probabilities:

Experimental probability:

The basis for experimental probability is what actually happens. It is dependent on the outcomes of several tests or experiments.

It is calculated by repeatedly recreating the event, recording the outcomes, and then converting the outcomes into a ratio or decimals.

Experimental probability = No of times event occurs/ No of trials

Theoretical Probability:

Theoretical probability is derived from a theory or what is predicted to occur. It is based on information and math.

It is determined by dividing the total number of outcomes by the proportion of favorable results. Either convert it to decimal form or leave it as a ratio or fraction.

Theoretical probability = No of favorable outcomes/ No of outcomes

Here we have

Tami rolled a die 20 times

14 times it landed on an even number;

6 times it landed on an odd number.

The die rolled for an odd number

As we a die will have 6 faces

Number of odd numbers = 3 [i.e 1, 3, 5 ]

Number of even numbers = 3 [ i.e 2, 4, 6 ]

⇒ Theoretical probability = 3/ 6 × 100 = 50%

The die is rolled 20 times, 6 times it landed on an odd number.

⇒ Experimental probability = 6 / 20 = 30%

As we can see,

The theoretical probability is higher than the Experimental probability.

Therefore,

The answer is the Theoretical probability is higher than the Experimental probability.

After a 90% reduction, you purchase a new soft drink machine on sale for $66. What was the original price of the soft drink machine?
The original price was
GEZER

Answers

Answer:

$660.

Step-by-step explanation:

So when we apply a discount to a product we multiply the price of the product (let's all is x) for the percentage of the discount (let's apply 90% as the probnlem says) so then we have the following operation:

x ⋅ (1-0.9) = y

Variable y is the price at which you bought the product, it's $66, on this case. Therefore, this is the expression we have:

x ⋅ (1-0.9) = $66

Now, to get the original value of the product (x), we solve the equation for x:

x ⋅ (1-0.9) = $66

x= $66 / (1-0.9)

x= $66 / (0.1)

x= $660

• Why did we multiply by 1-0.9?

This is because we were looking for the 10% of the original price, since it's a 90% discount. A simple way to solve the problem would've been to just divide the price by 0.1 (10%), because that's what remains after you discount 90% of the price.

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

A different example would be the following:

What was the original price of a product bought for $48 if it has a 60% discount?

x is original price.

Since a 60% discount was applied, 40% of the price remains at full price. Therefore, we multiply the original price (x) by 40%:

x ⋅ 40%= $48

x= $48 / 40%

x= $48 / 0.4

x= 120

$120 was the original price.

One environmental hazard recently identified is overexposure to airborne asbestos. In a sample of 10 public buildings over 20 years old, three were found to be insulated with materials that produced an excess number of airborne asbestos bodies. what is the approximate probability that another buitding of this rype will have this problem? What method are you using to assign this probability?

Answers

Answer:

1. 0.3

2. Relative frequency

Step-by-step explanation:

We would be calculating for p(A) which is the probability of A. With A being that public buildings would be found to be insulated with same materials that causes same issues

n = sample space of public buildings = 10

F = frequency = 3

P(A) = 3/10 = 0.3

Therefore 0.3 is the approximate probability of another building having same issues

Question 2 says we should find method used to assign probability

The method used is relative frequency method and it is determined by:

P(A) = frequency(f)/total number of data values(n).

if x and y vary directly and y is 33 when x is 11, find y when x is 12

Answers

Based on the direct variation relationship between x and y, where y is 33 when x is 11, we find that y is 36 when x is 12.

If x and y vary directly, it means that they have a constant ratio between them. We can express this relationship as:

y = kx,

where k is the constant of variation.

To find the value of k, we can use the given information that when x is 11, y is 33. Substituting these values into the equation, we have:

33 = k * 11.

Dividing both sides by 11, we find:

k = 3.

Now that we have determined the constant of variation, we can find y when x is 12 by substituting this value into the equation:

y = 3 * 12.

Evaluating this expression, we get:

y = 36.

Therefore, when x is 12, y will be 36.

Based on the direct variation relationship between x and y, where y is 33 when x is 11, we find that y is 36 when x is 12.

Luther prepared 18 kilograms of dough after working 6 hours. How many hours did Luther work if he prepared 21 kilograms of dough? Solve using unit rates.

Answers

We can use unit rates to solve this problem. We know that Luther prepared 18 kilograms of dough after working 6 hours, which means he prepared:

18 kg / 6 h = 3 kg/h

This is Luther's unit rate of dough preparation, which means he prepared 3 kilograms of dough per hour.

To find out how many hours Luther worked if he prepared 21 kilograms of dough, we can set up a proportion using his unit rate:

3 kg/h = 18 kg/6 h

We can simplify this proportion by multiplying both sides by 7:

21 kg/h = 126 kg/6 h

Now we can see that if Luther prepared 21 kilograms of dough, he must have worked:

6 h * (21 kg/h ÷ 18 kg/h) = 7 hours

Therefore, Luther worked for 7 hours if he prepared 21 kilograms of dough.

A ship is anchored off a long straight shoreline that runs north and south. From two observation points
miles apart on shore, the bearings of the ship are
and
. What is the distance from the ship to each of the observation points? Round each answer to the nearest tenth of a mile.

The distance from the north most ship to the observation is
miles.
The distance from the south most ship to the observation is
miles.

Answers

The distance from the north most ship to the observation is 2.9 miles and the distance from the south most ship to the observation is 9.9 miles.

The bearing is defined as the angle measured clockwise from the north direction. A ship is anchored off a long straight shoreline that runs north and south.

From two observation points miles apart on shore, the bearings of the ship are 52 degrees and 134 degrees respectively. To find the distance from the ship to each of the observation points, we can use trigonometry.

Let's call the distance from the north observation point to the ship x, and the distance from the south observation point to the ship y. The bearings from the north and south observation points can be drawn as follows:

[asy]

unitsize(1cm);

pair O = (0,0), N = (-2,0), S = (2,0), A = (-2,1), B = (2,-1);

draw(O--N--A,Arrow);

draw(O--S--B,Arrow);

$label("$52^\circ$", N + 0.3*dir(52), NE);$

$label("$134^\circ$", S + 0.3*dir(134), SE);$

draw(O--A--B--cycle,dashed);

$label("$x$", (N+A)/2, W);$

$label("$y$", (S+B)/2, E);$

[/asy]

We can use the tangent function to find x and y, since we have the angle and opposite side.

From the north observation point, we have:

$$$\tan(52^\circ) = \frac{x}{2}$$$$x = 2\tan(52^\circ) \approx 2.95$$$

From the south observation point, we have:

$$$\tan(134^\circ) = \frac{y}{2}$$$$y = 2\tan(134^\circ) \approx 9.88$$$

Therefore, the distance from the north most ship to the observation is 2.9 miles and the distance from the south most ship to the observation is 9.9 miles.
