If the mass of a box is 32 g and it's 4 cm wide 2 cm by 3 cm what is the density of the box

1 answer:

5 0

Density is mass/volume. The mass is given, 32g. To calculate volume, you need to multiply 4*2*3, which is multiplying length, width, and height.

4*2=8
8*3=24

To calculate density, you divide the mass (32) by the volume (24).

32/24= 1.3333333...

Your answer, depending on the person, would either be 1.33, 1.3, 1.33 with the line about the 2 3s, or 1 1/3. Hope this helps! Also, remember to label it g/cm2.

A student wants to simulate 31 birthdays, but she does not have a calculator or software program available, so she makes up 31

Answer:

No, it is not okay to conduct the simulation this way.

Step-by-step explanation:

In statistics, simulation refers to a technique that is employed to model random events so that the results obtained from using the simulation is significantly similar to the results obtained from observing the real-world.

Researchers are therefore able to understand the real world when they observe the simulated outcomes.

From the description above, it can be seen that simulation is about studying random events. Therefore, a sample of the population that will be used in the simulation must be selected through a random sampling.

Random sampling refers to the sampling method that gives equal opportunity of being selected to each member of the population. This makes the sample selected through random sampling technique to be an unbiased representation of the total population.

As a result, making up 31 numbers between 1 and 365 by the student is not a random sampling, because his method may favor some numbers over others. It is therefore a defective method of carrying out simulation.

Therefore, the it is not okay to conduct the simulation this way.

I wish you the best.

A golf player is trying to make a hole-in-one on the miniature golf green shown.

The path of the ball is an illustration of absolute equation.

The equation of the path is: $y =- \frac{12}7|x- 4.8| + 6.4$

The given parameters are:

$(h,k) = (4.8,6.4)$ --- the vertex (i.e. the point where the ball hits the wall)

$(x_1,y_1) = (2,1.6)$

$(x_2,y_2) = (7.6,1.6)$

An absolute function is represented as:

$y = a |x - h| + k$

Substitute $(h,k) = (4.8,6.4)$

$y = a |x - 4.8| + 6.4$

Substitute $(x_1,y_1) = (2,1.6)$ for x and y

$1.6 = a|2 - 4.8| + 6.4$

$1.6 = a|- 2.8| + 6.4$

Remove absolute bracket

$1.6 = 2.8a + 6.4$

Collect like terms

$2.8a = -6.4+1.6$

$2.8a =- 4.8$

Solve for a

$a =-\frac{4.8}{2.8}$

Simplify

$a =-\frac{12}{7}$

Substitute $a =-\frac{12}{7}$ in $y = a |x - 4.8| + 6.4$

$y =- \frac{12}7|x- 4.8| + 6.4$

Hence, the equation of the path is: $y =- \frac{12}7|x- 4.8| + 6.4$

See attachment for graph that models the path

Which of the following is true for most distributions? Group of answer choices

Drupady [299]

Answer:

Step-by-step explanation:

The standard deviation is a measure that tells us how far measures tend to be from the mean. A low standard deviation gives us values closer to the mean than a high standard deviation. Usually 68% of the data falls within one standard deviation of the set.

Thus, the most accurate answer would be a) Around 70% of the scores will be located within one standard deviation of the mean
