1. A standard dice has 6 sides with the numbers 1-6 on it. What is the probability of rolling a 4 on a
standard dice?
Answer:
1/6
Step-by-step explanation:
There are six sides on a die and only one of them has a 4
P( 4) = number of sides with a 4/ total number of sides
= 1/6
Answer:
P (4) = 1/6
Step-by-step explanation:
The probability can be found by creating a fraction. The numerator is the number of favorable outcomes and the denominator is the total number of outcomes.
P (4) = sides with a 4 / total sides
The standard dice has 6 sides numbered 1 through 6.
P (4) = sides with a 4/ 6
Only one side on the cube has a 4.
P (4) = 1/6
This fraction cannot be simplified further, so it is our final answer.
The probability of rolling a 4 on a standard dice is 1/6
There are three numbers. The first number is twice the second number. The third number is twice the first number. The sum of the three numbers is 112.
Answer:
x = 32 y = 16 z = 64
Step-by-step explanation:
x is the 1st number
y is the 2nd number
z is the 3rd number
The first number is twice the second number so
x = 2 y
The third number is twice the first number.
z = 2 x
Their sum is 112
x + y + z = 112
Plus in what we know:
x + y + z = 112
2 y + y + 2x = 112
3y + 2x = 112 Let's solve for y and subtract 2x from each side
3y = 112 - 2x Divide both sides by 3
y = [tex]\frac{112 - 2x}{3}[/tex]
Now plug our answer back in to solve for x.
x = 2y
x = 2 ( [tex]\frac{112 - 2x}{3}[/tex] )
x = (224 - 4x) / 3 Multiply each side by 3.
3x = 224 - 4x Add 4x to each side
3x + 4x = 224
7x = 224 Divide each side by 7
7x / 7 = 224 / 7
x = 32
Now we can solve for z.
z = 2x
z = 2 ( 32 )
z = 64
Now we can solve for the numerical value of y.
x + y + z = 112
32 + y + 64 = 112
96 + y = 112 Subtract 96 from each side.
y = 112 - 96
y = 16
Answer:
1st number = 36
Second = 16
Third = 64
Step-by-step explanation:
We have 3 numbers
Let's call the second number g
Then the first would be , 2x g = 2g
Then the third would be twice the first = 2 x 2g = 4g
We add up all numbers and equate it to 112
2g + g +4g = 112
7g = 112
g = 112/7
g = 16
First number = 2g = 2x16 = 32
Second number = g = 16
Third number = 4g = 4x16 = 64
Therefore the numbers are 32, 16, 64.
I hope this helps!

A'' = (-1; 6)A grocery store has small bags of apples for 5$ and large bags of apples for 8$. If you buy 6 bags of apples and spend 45$, how many of each bags did you buy?
Answer:
He bought 1 small bag and 6 large bags.
Step-by-step explanation:
We can set up 2 equations with the given information.
5x+8y=45
x+y=6
We can rearrange the second equation to solve for x.
x=6-y
Now we substitute x for 6-y in the first equation
5(6-y)+8y=45
30-5y+8y=45
30+3y=45
y+10=15
y=5
x=1
He bought 1 small bag and 6 large bags.

solve equation by taking square roots n^2+4=40
Answer:
n = ±6
Step-by-step explanation:
n² + 4 = 40
n can be solved by finding the square root
n² = 40 - 4
n² = 36
n = √36
n = ±6
One number is 9 more than twice another number. If the sum of the numbers is 129, find both numbers.
Answer:
40 and 89
Step-by-step explanation:
let x be the number then the other number is 2x + 9, then
x + 2x + 9 = 129, that is
3x + 9 = 129 ( subtract 9 from both sides )
3x = 120 ( divide both sides by 3 )
x = 40
Thus the numbers are
x = 40 and 2x + 9 = 2(40) + 9 = 80 + 9 = 89

Which statement is supported by the histograms? The two data sets have the same distribution and same range. The two data sets have the same distribution but different ranges. The two data sets have different distributions but the same range. The two data sets have different distributions and different ranges.
Answer:
The two data sets have different distributions and different ranges.
Step-by-step explanation:
When you subtract for both of the ranges they are different numbers. So that's the second part. The numbers along the bottom are different too so that is the different distributions.
Answer:
The two data sets have different distributions and different ranges.
Step-by-step explanation:
The shape of the data for German male adult heights is skewed left, but the shape of the data for female adult heights is close to symmetric. So, the two data sets have different distributions.
Each data set has the same minimum height of 145 centimeters. However, the maximum male adult height is 220 centimeters, and the maximum female height is 185 centimeters. So, the two data sets have different ranges.

[tex]\overrightarrow{AB}=\overrightarrow{OA}-\overrightarrow{OB}= \left[\big5\atop\big3\right]-\left[\big2\atop-\big5\right]= \left[\big5-\big2\atop\big3-(-\big5)\right]=\left[\big3\atop\big8\right][/tex]
2. Calculating length of [tex]\overrightarrow{OA}\,,\ \overrightarrow{OB}\ \text{and}\ \overrightarrow{AB}[/tex]:
[tex]|\overrightarrow{OA}|=\sqrt{5^2+3^2}=\sqrt{25+9}=\sqrt{34}\approx5.831\\\\ |\overrightarrow{OB}|=\sqrt{2^2+(-5)^2}=\sqrt{4+25}=\sqrt{29}\approx5.385\\\\ |\overrightarrow{AB}|=\sqrt{3^2+8^2}=\sqrt{9+64}=\sqrt{73}\approx8.544[/tex]

Complete question:
In 2016, the city of Rio de Janeiro had a population density of 5377 people/km2.
What was the population density of Rio in people per square meter?
Answer:
0.005377 peope/m²
Step-by-step explanation:
Given that :
Population density of Rio in 2016 = 5377 people/km²
To obtain population density in people per square meter, we convert 5377people/km² to people per m²
Recall:
1000 m = 1km
Hence,
5377 people/km² = 5377 people / (1000²)m
= (5377/1000000)people/m²
= 0.005377 peope/m²

The number of books Jason reads each week is inversely proportional to the number of hours he spends with his friends if Jason read three books and spent four hours with his friends one week how many books does he read during the week in which he spent six hours with his friends
Answer:
Number of books= 2 books
Step-by-step explanation:
number of books Jason reads each week is inversely proportional to the number of hours
Let books be x
Let hours be y
X= k/y
Where k is constant of proportionality
Jason read three books and spent four hours
3= k/4
3*4= k
12= k
So
X= 12/y
If he spent six hours
Number of books x
X= 12/6
X= 2 books

a line of best fit for the data is y=0.9x-4.5, where x represents age in year, and in years, and y represents hourly pay, in dollars.Based on the data, what is the best prediction for the hourly pay of a 25 year old?
Answer:
$18
Step-by-step explanation:
Given:
y = 0.9x - 4.5
Where,
x = age in years
y = hourly pay in dollars
what is the best prediction for the hourly pay of a 25 year old?
That is, find y when x=25
y = 0.9x - 4.5
= 0.9(25) - 4.5
= 22.5 - 4.5
= 18
y = $18
The prediction for the hourly pay of a 25 year old is $18
