Answer:
The information that we have is:
"The graph of y=-1/2x+2 is positive over the interval negative infinity and 4 and negative over the interval 4 and infinity."
Now, i guess that the question is:
"What happens on the graph when x = 4 ?"
Well, if for values of x smaller than 4 the graph is negative and for values of x larger than 4 the graph is positive, this must that the graph must cross the x-axis at some point, then with only that information, we can conclude that the graph is equal to zero when x = 4.
But we could also test it with the equation:
y = -(1/2)*x + 2
if we replace the x by a 4.
y = -(1/2)*4 + 2 = -2 + 2 = 0.
Then our previous hypothesis was correct.
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.

Step-by-step explanation:
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
what’s the square root of 5 times the square root of 5 ??
Answer:
5
Step-by-step explanation:
Whenever you multiply square roots that have the same number inside the radicand, you get the number under the radicand. For example, the square root of 4 squared will equal four. Similarly, you are simply squaring the square root of 5, so you should get 5 as your answer.
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
One positive number is 6 times another number. The difference between the two numbers is 205. Find the numbers. (Enter your answers as a comma-separated list.)
Answer:
Hence the positive numbers are 246, and 41
(246, 41)
Step-by-step explanation:
From the question,
One positive number is 6 times another numberLet the first positve number be [tex]x[/tex]
and the other number be [tex]y[/tex]
Hence,
[tex]x = 6y[/tex] ....... (1)
Also,
The difference between the two numbers is 205That is,
[tex]x - y =205[/tex] ........(2).
To solve for the two unknowns, substitute the value of [tex]x[/tex] in equation (1) into equation (2).
Since,
[tex]x = 6y[/tex]
Then
[tex]x - y =205[/tex] becomes
[tex](6y) - y =205\\[/tex]
Then,
[tex]6y - y = 205\\5y = 205\\[/tex]
Divide both sides by 5
[tex]\frac{5y}{5} = \frac{205}{5} \\ y = 41\\[/tex]
∴ the value of [tex]y[/tex] is 41
Now, substitute the value of y into equation (1) to find [tex]x[/tex]
Then,
[tex]x = 6y[/tex] becomes
[tex]x = 6(41)\\x = 246\\[/tex]
∴ the value of [tex]x[/tex] is 246
Hence the positive numbers are 246, and 41
(246, 41)

I NEED HELP WITH THESE RNNNN!!!!!!!
Answer:
Step-by-step explanation:
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.

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.
On Novenber 4, your bank statement shows a balance of $2,253.18. Your checkbook shows a balance of $2,324.34. If there are outstanding checks in the amounts of $105.50 and $158.10, deposits in transit amount to $605.27, account earnings of $68.51 and there is a service charge of $5.00. Determine the Adjusted Checkbook Balance and the Adjusted Statement Balance.
Answer:
The final answer is "$2387.85 and $2594.85".
Step-by-step explanation:
Given values:
The bank statement balance= $2,253.18
The checkbook balance = $2,324.34
outstanding check amounts= $105.50 and $158.10
transit amount= $605.27
account earnin(credits)= $68.51
service charge= $5.00
Adjusted Checkbook Balance =?
Adjusted Statement Balance=?
Adjusted the Checkbook Balance:
checkbook balance = $2,324.34
[tex]\text{total checkbook balance = checkbook balance+ credits}\\[/tex]
[tex]= \$ 2,324.34+ \$ 68.51\\\\= \$ 2392.85[/tex]
[tex]\text{ Adjust check book balance= total checkbook balance - servicec charge}[/tex]
[tex]= \$2392.85 - \$5.00\\\\= \$ 2387.85[/tex]
Adjusted the Statement Balance:
bank statement balance= $2,253.18
[tex]\text{total Statement balance = bank Statement balance+ transit amount}\\[/tex]
[tex]= \$ 2,253.18+ \$ 605.27\\\\= $ 2,858.45[/tex]
[tex]\text{outstanding check amounts = $105.50+ $158.10}[/tex]
[tex]= \$263.60[/tex]
[tex]\text{ Adjust statement balance= total statement balance - outstanding check amount }[/tex] [tex]= \$ 2,858.45 - \$263.60\\\\= $ 2,594.85[/tex]

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
