Can someone help me out with this? 6 balls numbered from 1 to 6 are placed in a Jar. If 1 ball is selected at random, find the probability that it is number 1 in decimal form,rounded to two decimal places.
Answers
The probability that a ball selected at random from the jar is number 1, rounded to two decimal places, is 0.17.
To find the probability of selecting ball number 1 from a jar containing 6 balls numbered from 1 to 6, we need to determine the number of favorable outcomes (selecting ball number 1) and the total number of possible outcomes.
The total number of possible outcomes is 6 since there are 6 balls in the jar.
The number of favorable outcomes is 1 since we are interested in selecting ball number 1.
Therefore, the probability of selecting ball number 1 is given by:
Probability = Number of Favorable Outcomes / Total Number of Possible Outcomes
Probability = 1 / 6
To express this probability in decimal form, we divide 1 by 6:
Probability ≈ 0.1666667
Rounded to two decimal places, the probability of selecting ball number 1 is approximately 0.17.

Answer:
3 3/18
Step-by-step explanation:
5 3/6-2 1/3
We first need to turn our mixed numbers into fractions by multiplying the while number by the denominator, then adding the numerator. When we do this, 5 3/6 turns into 33/6 and 2 1/3 turns into 7/3. Now we have this:
33/6-7/3
Now we need to find the Least common multiple of the denominators in order to find our common denominator, which in this case is 6. 33/6 already has a denominator of 6, so we do not need to do anything to it. To give a denominator of 6 to 7/3, however, we must multiply by 2, giving us this:
33/6-14/6
Now we can subtract the numerators.
19/6
To turn this back into a mixed number, we divide 19 by 6, which gives us 3 with a remainder of 1. Therefore, our answer is 3 1/6. This is an equivalent fraction to the fourth answer, 3 3/18.

a. For any function, in order for a vertical stretch to happen, a must be greater than 1 so the answer to a is
a>1.
b. For b, the graph will compress when a is between 0 and 1 but not equal to both.
So the answer to. b is
0<a<1.
c.A vertical stretch happens when a>1, a horinzontal compression also happens when a>1, if you confused let me explain
Consider the graph above. Let say we have a quadratic function
\((x - 3) {}^{2} \)
Let that be the parent function, if we stretch the function, a must be greater than 1 as we established in a.
In the fist picture, let say a=2.7
The function is stretched in the vertical direction
Now, let say if we affect x.
Here, let a=2.7 we know have
The function is being compressed when a>1, so that means that
we stretched vertically or compressed horizontally when a>1. It depends on the location of a. If a is outside the parenthesis, we will stretch by a factor of a. If a is I side the parenthesis, we will compress by a factor of a.
d. A must be negative or a<0

Rajek, a truck driver, hauls containers for his customers. One customer wants to know the total amount of cardboard that can fit in a container at one time. The truck Rajek uses is shown below.
The base of the container has an area of 50 1/4 square feet.

Step-by-step explanation:

We have,
To find the total amount of cardboard that can fit in the container at one time, we need to find the surface area of the container.
The container has a rectangular base with an area of 50 1/4 square feet.
Let's assume the length of the base is L and the width is W.
We know that:
L x W = 50 1/4
We also know that the height of the container is 4(1/2) feet, which is equivalent to 9/2 feet.
The container has two identical sides, which are rectangles with a length of L and a height of 9/2 feet.
The surface area of one side is:
L x (9/2) = (9/2)L
The container also has two identical ends, which are rectangles with a width of W and a height of 9/2 feet.
The surface area of one end is:
W x (9/2) = (9/2)W
Finally, the container has a top, which is a rectangle with a length of L and a width of W.
The surface area of the top is:
L x W
To find the total surface area of the container, we add up the surface area of each of these parts:
Total surface area = 2(L x (9/2)) + 2(W x (9/2)) + (L x W)
Simplifying this expression, we get:
Total surface area = 9L + 9W + LW
We know that L x W = 50 1/4, so we can substitute this into the equation:
Thus,
The total surface area of the container is 9L + 9W + 50 1/4

From the graph, we can see that it passes through the points (0,-3) and (-5,1) . Using these two points,we can find the slope of the line as ,

And here ,
\( x_1 = 0 \)\( x_2 = -5 \)\( y_1 = -3 \)\( y_2 = 1\)So , on substituting the respective values, we have;
\(\implies m =\dfrac{1-(-3)}{-5-0} \\\)
\(\implies m = \dfrac{ 1+3}{-5} \\\)
\(\implies m =-\dfrac{4}{5} \\\)
Here the graph , cuts the y axis at (0,-3) . So the y- intercept of the graph is -3 . Now we may use the slope intercept form of the line to find the function . The slope intercept form of the line is \( y = mx + c\) , where ;
\( c\) is y intercept\( m\) is the slope.And here ,
\( m =-\dfrac{4}{5} \)\( c = -3\)Again, on substituting the respective values, we have;
\(\implies y = \dfrac{-4}{5}x + (-3) \\\)
\(\implies y =\dfrac{-4}{5}x - 3 \\\)
Replace \( y \) with \( f(x)\)

The teacher can thus use social sciences as a vehicle to develop mathematical skills by facilitating the development of skills such as data interpretation and analysis.
As an instructor, I would use social sciences to develop mathematical skills in the following manner:Consider a social science topic like demography. In this case, a teacher could use mathematics to assist students in interpreting population statistics.
Teachers might guide students to gather information about population size, growth rate, and geographical distribution from various countries and then use statistics to analyze the data.
For example, a teacher could give students graphs or charts to help them understand population growth rates. They can be asked to make comparisons and identify trends.
In this way, students' understanding of the population is improved, as is their mathematical reasoning.Aside from using mathematics to interpret population statistics,
the teacher can also incorporate mathematical skills development in social sciences by using methods that involve understanding and analysis of data. In other words, students learn how to use data to reach conclusions and make decisions.
They learn how to interpret data and how to extract information from it.This method of teaching creates opportunities for the use of the same skills in different contexts and areas of learning.
It enables students to see connections between subjects and fosters an integrated approach to learning.

Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.

Hence the 90% confidence interval estimate of the population mean is \((79.24 , 97.44)\)
Step-by-step explanation:
Given that,
Point estimate = sample mean = \(\bar x\) = 88.34
sample standard deviation = s = 19.22
sample size = n = 14
Degrees of freedom = df = n - 1 = 13
Critical value =\(t\alpha /2,\) df = 1.771
Margin of error
\(E = t\alpha/2,df \times (\frac{s}{\sqrt{n} } )\\= 1.771 \times (19.22 / \sqrt 14)\)
Margin of error = E = 9.10
The 90% confidence interval estimate of the population mean is,
\(\bar x - E < \mu < \bar x + E\\\\88.34 - 9.10 < \mu < 88.34 + 9.10\\\\79.24 < \mu < 97.44\\(79.24 , 97.44)\)
