Answer:
9
Step-by-step explanation:
average = [tex]\frac{sum of patients}{number of assistants}[/tex]
= [tex]\frac{7+8+5+9+10+10+14}{7}[/tex] = [tex]\frac{63}{7}[/tex] = 9
To get this answer you need to find the average. To find the average, you need to add the number of patients for each assistant together.
7 + 8 + 5 + 9 + 10 + 10 + 14 = 63
Then divide the answer by the number of assistants.
63 / 7 = 9
So, the answer is 9. There are an average of 9 patients per nurse.
Factor the expression P^4+3p^3-10p^2
Answer:
[tex]p^2(p+5)(p-2)[/tex]
Step-by-step explanation:
To begin factoring the expression [tex]p^4+3p^3-10p^2[/tex], we use the GCF or greatest common factor. The greatest common factor is the greatest number that will divide into two or more values. We start to find it by factoring each term:
[tex]p^4=p*p*p*p[/tex]
[tex]3p^3: 3*p*p*p[/tex]
[tex]-10p^2: -10*p*p[/tex]
Remember -10 can factor into smaller numbers but since it doesn't have common factors with the others, we've chosen to leave it as -10.
We notice the only common factors bare p*p or [tex]p^2[/tex].
We write in the form p^2(____+_____+_____). We find the inside of the parenthesis by dividing each term by p^2.
[tex]\frac{p^4}{p^2} =p^2[/tex]
[tex]\frac{3p^3}{p^2} =3p[/tex]
[tex]\frac{-10p^2}{p^2}=-10[/tex]
[tex]p^2(p^2+3p-10)[/tex].
We are not finished yet. We have a trinomial (3 terms) which also factors. We factor by splitting the middle term 3p into factors of -10 which add to 3.
--10 = 5 * -2
3p= 5p +-2p
We write [tex]p^2(p+5)(p-2)[/tex].

I think the equation is 7l +5=60
Step-by-step explanation:
2x + 5y = 17 and 6x - 5y = -9 what is the solution of the system use elimination
x = 8.5 + 2.5y answer one can’t figure out answer two. Sorry
Answer:
{x = 1 , y = 3
Step-by-step explanation:
Solve the following system: using elimination:
{2 x + 5 y = 17 | (equation 1)
{6 x - 5 y = -9 | (equation 2)
Swap equation 1 with equation 2:
{6 x - 5 y = -9 | (equation 1)
{2 x + 5 y = 17 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{6 x - 5 y = -9 | (equation 1)
{0 x+(20 y)/3 = 20 | (equation 2)
Multiply equation 2 by 3/20:
{6 x - 5 y = -9 | (equation 1)
{0 x+y = 3 | (equation 2)
Add 5 × (equation 2) to equation 1:
{6 x+0 y = 6 | (equation 1)
{0 x+y = 3 | (equation 2)
Divide equation 1 by 6:
{x+0 y = 1 | (equation 1)
{0 x+y = 3 | (equation 2)
Collect results:
Answer: {x = 1 , y = 3
What is the probability that someone in the survey considered reading books or surf the internet as the best entertainment?
Answer:
31/100
Step-by-step explanation:
From the given table
Reading books percentage is 22
so Probability (reading books) = [tex]\frac{22}{100}[/tex]
Surf the internet percentage is 9
Probability (surf the internet) =[tex]\frac{9}{100}[/tex]
the probability (reading books or surf the internet)= P(reading books) + P(surf the internet)
probability (reading or surf)= [tex]\frac{22}{100} +\frac{9}{100}[/tex]
= [tex]\frac{31}{100} [/tex]
Answer:
Answer is [tex]\frac{31}{100}[/tex]
Step-by-step explanation:
values given in table
Reading books percentage is 22
hence we can write probability as
Probability (reading books) = [tex]\frac{22}{100}[/tex]
percentage of surfing internet is= 9
Probability of surfing internet is =[tex]\frac{09}{100}[/tex]
the probability (reading books or surf the internet)= P(reading books) + P(surf the internet)
probability (reading or surf)= [tex]\frac{22}{100}[/tex]+[tex]\frac{09}{100}[/tex]
=[tex]\frac{31}{100}[/tex]

Answer: 4 cups of milk
=============================
Work Shown:
2 & 1/2 = 2 + 1/2 = 2+0.5 = 2.5
2.5 cups of milk makes 5 servings
x cups of milk makes 8 servings
Divide the cups of milk over the servings to get this proportion
2.5/5 = x/8
Cross multiply and solve for x
2.5/5 = x/8
2.5*8 = 5*x
20 = 5*x
5*x = 20
x = 20/5
x = 4
You need 4 cups of milk to make 8 servings
The sale price of an item is 0.75 the original price of the item, x. Which statement explains why both 3 4 x and 0.75x can find the sale price of the item? The fraction 3 4 is the same as the decimal 0.25. Therefore, 3 4 x can be written as 0.25x. Multiplying by 4 3 is the same as multiplying by 0.8. The expressions are not equivalent. Multiplying by 3 4 is the same as multiplying by 75%.
Answer:
Answer. Multiplying by 3/4 is the same as multiplying by 75%.
Step-by-step explanation:
Last option: Multiplying by 3/4 is the same as multiplying by 75%, because:
3/4=0.75 and
75%=75/100=0.75
then 3/4=0.75=75%

Given the equation: y−6=1/2(x+2) in point slope form, rewrite the equation into standard form. Show your work for full credit.
Answer:
x - 2y = - 14
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
given y - 6 = [tex]\frac{1}{2}[/tex](x + 2)
multiply all terms by 2 to eliminate the fraction
2y - 12 = x + 2 ( subtract 2 from both sides )
2y - 14 = x ( subtract 2y from both sides )
- 14 = x - 2y, hence
x - 2y = - 14 ← in standard form

angle rst = 2x+8, angle tsw= 3x+14, angle rsw= 7x-2. find tsw. apparently x= 12, but idk the steps to get it bc whatever i do, i get 6x=8... please help
Answer:
angle(TSW) is 18
Step-by-step explanation:
we are given angles
angle(RST)=2x+8
angle(TSW)=3x+14
angle(RSW)=7x-2
Firstly, we will draw diagram
so, we get
angle(TSW)=angle(RST)+angle(RSW)
so, we can plug values
[tex]3x+14=2x+8+7x-2[/tex]
now, we can solve for x
[tex]9x-3x=14-6[/tex]
[tex]6x=8[/tex]
now, we can solve for x
[tex]x=\frac{4}{3}[/tex]
now, we can find angle (TSW)
angle(TSW) is
[tex]=3\times \frac{4}{3} +14[/tex]
[tex]=4 +14[/tex]
[tex]=18[/tex]
So, angle(TSW) is 18
To solve for x, we set up an equation based on the sum of angles forming a straight line. Solving the equation, we find x=12. Substituting x into the equation for angle tsw, we find that angle tsw measures 50 degrees.
To find the value of x for the angles rst, tsw, and rsw, you need to understand that they are all connected by their location on a straight line or a point. If angles rst and tsw are adjacent angles that form a straight line, their measures would add up to 180° because a straight line measures 180°. The same is true for the angle rsw if it is the full angle at that point or the sum of angles rst and tsw.
The equations are given as:
angle rst = 2x + 8angle tsw = 3x + 14angle rsw = 7x - 2Since angle rsw is the full angle, you can write the equation:
7x - 2 = (2x + 8) + (3x + 14)
Now, solve for x:
7x - 2 = 2x + 8 + 3x + 14
7x - 2 = 5x + 22
7x - 5x = 22 + 2
2x = 24
x = 24 / 2
x = 12
Now that we have the value of x, we can find angle tsw by substituting x into its equation:
angle tsw = 3x + 14
angle tsw = 3(12) + 14
angle tsw = 36 + 14
angle tsw = 50°

Diego has 49 square inch tiles. He wants to use to make a square mosaic. How long can each side of the mosaic be?
Answer:
side of the mosaic = 7 inches
Step-by-step explanation:
Diego has 49 square inch tiles. He wants to use to make a square mosaic.
Area of the tile = 49 square inches
We know , area of the square = s^2
where 's' is the side of the square
[tex]Area = s^2[/tex]
Plug in 49 for area and solve for 's'
[tex]49 = s^2[/tex]
Take square root on both sides
s= 7
side of the square = 7 inches
Diego can make a square mosaic where each side is 7 inches using his 49 square-inch tiles. This is found by calculating the square root of the total area.
Explanation:The subject of this question is Mathematics, specifically dealing with square roots and area calculations. Diego has 49 square inch tiles and wants to make a square mosaic. Since a square has equal sides, the length of each side of the mosaic will be the square root of the total area. The total area of the tiles is 49 square inches. The square root of 49 is 7. Therefore, each side of Diego's mosaic will be 7 inches in length. This conclusion is reached by understanding how the area of a square works. The area of a square can be calculated by multiplying the length of one side by the length of another side. When we know the total area, we can find the length of one side by taking the square root.

Given: line segment AB is 10 inches long.
Find the length of A'B' if AB is dilated to form A'B' with a scale factor of 2.
A) 1/2 inches
B) 5 inches
C)10 inches
D)20 inches
Answer:
D or 20
Step-by-step explanation:
If the scale factor is 2 then you take the original number, 10, and multiply it by 2.
10*2=20
Answer:
Option D). 20 inches
Step-by-step explanation:
Length of AB which is of length = 10 inches.
If the length of AB is dilated to form A'B' with a scale factor of 2, then we have to find the length of A'B'
Since we know the formula of dilation as
New dimension = Scale factor × Old dimension
So A'B' = Scale factor × AB
A'B' = 2× 10 = 20 Inches
Option D). 20 inches is the solution.
What is the slope of the line
Answer:
The slope is 7/4.
What is the equation of a line with a slope of 7 and a point (1, 8) on the line?
Express the equation in the form of y = mx + b, where m is the slope and b is the y-intercept.
Enter your answer in the box.
Answer:
y = 7x + 1
Step-by-step explanation:
If the slope and coordinates have already been given, you can plug the values into the following equation of a line:
y - y1 = m(x - x1)
Where y1 is the y coordinate, so in this case 8,
x1 is the x coordinate which is 1
m is the slope, so 7:
y - 8 = 7(x - 1)
Expand the brackets:
y - 8 = 7x - 7
To isolate the y, we need to move the -8 over to the other side making it a positive 8:
y = 7x - 7 + 8
y = 7x + 1
So the equation of the line is y = 7x + 1

How many degrees are each angle of a regular 7 sided shape?
Answer:
Step-by-step explanation:
Here is a diagram of a seven sided regular polygon. You use this diagram to find out how many degrees total are in the interior of a the heptagon. There are 5 such triangles which means that since each triangle has 180o the total amount of the interior angles must be 5 * 180 = 900
Since there are 7 interior angles, the answer to how large each one of them is is found by
900/7 = 129.57 which is slightly off because it is a rounded error.
In general, the size of the angles in a regular polygon
180(n - 2 ) / n
Where n is the number of degrees in each interior angle. For example for an 8 sided figure you would get
180(8 - 2) / 8 = 180 * 6/8 = 133 degrees.
word form of 16.0215
Answer: sixteen and two-hundred fifteen ten thousandths
You'd have to correspond the numbers to words and associate the period with and
Answer: Sixteen and two hundred fifteen ten-thousandths
We read off "16" as normal. Nothing too special about it.
The same goes for the 0215 which is really just 215, even though this part is after the decimal point. However, because it is after the decimal point, we tack on a "ten thousandths" to indicate it's a fractional non-whole portion
Note: if you change the 0 to something like a 3, then we would have 3215 which is less than ten-thousand. This might help you remember that four decimal spots out is the ten-thousandth place value.
another note: the "and" mentioned in the answer is a key word that indicates "decimal point". Only use it for decimal points. Do not use it for a number like "215". In other words, don't say "two hundred and fifteen" because that might seem like you are trying to say 2.15 or something along those lines.
