Janice bought juice packets for the 15 players on the soccer team The juice packets come in boxes of 6 How many boxes did Janice buy?
Answer:
3 boxes.
Step-by-step explanation:
We are told that Janice bought juice packets for the 15 players on the soccer team. The juice packets come in boxes of 6.
To find the number of boxes that Janice need to buy for 25 players, we will divide 15 by 6.
[tex]\text{Number of boxes that Janice needs to buy}=\frac{15}{6}[/tex]
[tex]\text{Number of boxes that Janice needs to buy}=2.5[/tex]
Since the juice packets come in boxes of 6, so we will round our answer to nearest whole number.
[tex]\text{Number of boxes that Janice needs to buy}=2.5\approx 3[/tex]
Therefore, Janice will buy 3 boxes of juice packets for 15 players.
The question entails a simple division operation of 15 players divided by 6 juice packets per box which gives 2.5. However, since Janice can't buy half a box, she ends up buying 3 boxes of juice packets.
Explanation:To answer your question, we need to perform a simple division arithmetic operation. This involves taking the total number of players which is 15 and dividing that by the number of juice packets in one box, which is 6 . The calculation is as follows: 15 ÷ 6 = 2.5. However, Janice cannot purchase half of a box so she would need to round up to the nearest whole number. Hence, Janice bought 3 boxes of juice packets for the soccer team.

Answer:
E.
Step-by-step explanation:
Even though we have a sample of 40 units, we cannot determine that the units that are not in the sample will have the same or similar quality as the units that are in the sample. Thus none of the conclusions can be true.
Answer: Choice B) 100 pieces must be defective
Assuming the sample selected is representative of the population, we have two copies of "25" in that list (row 4; row 8) out of 40 total. So 2/40 = 1/20 = 0.05 = 5% of the items should be defective out of the entire population. Again this is assuming the sample is representative.
So we take 5% of 2000 and we end up with 0.05*2000 = 100 items we expect to be defective from a sample of 2000 items. Keep in mind that the true count will probably not be 100 items but some value close around it (eg: 98 or 101). This value is an estimate and not always perfect.
If choice B said "around 100" or "about 100" or "approximately 100" then I think it would be more technically correct. I think this is what your teacher is after.

What is the remainder when you divide 4x^3 - 5x^2 + 3x - 1 by x - 2?
Answer: D
Step-by-step explanation:
x - 2 = 0 --> x = 2
Using synthetic division:
2 | 4 -5 3 -1
| ↓ 8 6 18
4 3 9 17 ← this is the remainder!
Using remainder theorem:
f(x) = 4x³ - 5x² + 3x - 1
f(2) = 4(2)³ - 5(2)² + 3(2) - 1
= 32 - 20 + 6 - 1

What is the linear function equation that is represented in the graph?
Answer: y = (-1/2)*x + 1
Step-by-step explanation:
In the graph we can see a linear equation, the first thing we know is that a linear equation has the shape of:
y = ax + b
first, to find the slope we can use two pairs of the graphed ones, in the notation (x,y) we can select the pairs: (0, 1) and (2, 0)
we have that a = (y2 - y1)/(x2 - x1)
a = (0 - 1)/(2- 0 ) = -1/2
so the slope is -1/2
now, b is the y-intercept, this is the value of y when x = 0, and we can see that this value is 1 (the point where the graph intercepts the y-axis) so b = 1.
then the equation is y = (-1/2)*x + 1
Solve.
{5x+y=2
{4x+y=4
Use the linear combination method.
(1, −8)
(0, 2)
(−2, 12)
(−3, 17)
Given these two equations:
1) 5x + y = 2
2) 4x + y = 4
Let's solve for x and y step by step.
Step 1: We start by subtracting equation (2) from equation (1) to eliminate y:
This gives us:
5x - 4x = 2 - 4
Which simplifies to:
x = -2
Step 2: Now, we substitute x = -2 into the equation (1) to find the value of y:
5*(-2) + y = 2
Which simplifies to:
-10 + y = 2
And therefore:
y = 12
So, the solution to the system of equations is x = -2 and y = 12.

Step-by-Step Explanation:
A polynomial graph has several features we look for to determine the equations.
The zeros of the function are the x-intercepts. If the x-intercepts touch but do not cross then the intercepts have an even multiplicity like 2, 4, 6, etc. If the x-intercepts cross over then they have an odd multiplicity.Degree is the exponent or multiplicity of each zero. Therefore if we know the multiplicity of each zero we can add them together to find or make an educated guess for the degree of the entire polynomial.The shape of the graph tells us what type of polynomial. Odd degrees have a backwards S shape. Even degrees have a W shape. The shape can even tell us the if the equation has a positive or negative leading coefficient. Upside down W or an M shape is negative. While a sideways S shape is negative.In this graph, there is one real zero: -4
We can write them in intercept or factored form as (x+4) since x+4=0 gives x=-4.
Because the graph never crosses the x-axis it has an even multiplicity of at least 2.
The graph is facing up and is a U shape. This can only be a quadratic of degree 2. It is positive.
This means the function has a degree of 2.

Andy buys x cakes. Betty buys 4 times as many cakes as Andy. Colin buys 3 more cakes than Andy. Each cake costs 65p. The total cost of the cakes is ?52.65. How many cakes did each person buy?
Answer:
Andy bought = 13 cakes.
Betty bought = 52 cakes.
Colin bought = 16 cakes.
Step-by-step explanation:
We are told that Andy buys x cakes. Betty buys 4 times as many cakes as Andy. So number of cakes bought by Betty will be 4*x.
We are also told that Colin buys 3 more cakes than Andy. So number of cakes bought by Colin will be x+3 cakes.
Each cake costs 65 p. The total cost of the cakes is $52.65. We can represent this information as:
[tex]0.65(x+4*x+x+3)=52.65[/tex]
[tex]0.65(2x+4*x+3)=52.65[/tex]
[tex]1.3x+2.6x+1.95=52.65[/tex]
Let us combine like terms.
[tex](1.3+2.6)x+1.95=52.65[/tex]
[tex]3.9x+1.95=52.65[/tex]
[tex]3.9x=52.65-1.95[/tex]
[tex]3.9x=50.7[/tex]
[tex]x=13[/tex]
Therefore, Andy bought 13 cakes.
Let us find number of cakes bought by Betty by substituting x=13 in expression 4*x.
[tex]\text{Cakes bought by Betty}=4*13[/tex]
[tex]\text{Cakes bought by Betty}=52[/tex]
Therefore, Betty bought 52 cakes.
Now we will find number of cakes bought by Colin by substituting x=13 in expression x+3.
[tex]\text{Cakes bought by Colin}=13+3[/tex]
[tex]\text{Cakes bought by Colin}=16[/tex]
Therefore, Colin bought 16 cakes.
Andy bought 13 cakes, Betty bought 52 cakes, and Colin bought 16 cakes.
Explanation:Let's break down the given information and solve the problem step by step:
Let the number of cakes bought by Andy be x.
Betty buys 4 times as many cakes as Andy, so she buys 4x cakes.
Colin buys 3 more cakes than Andy, so he buys (x+3) cakes.
The total cost of the cakes is €52.65, and each cake costs 65p.
Now, we can create the equation to find the value of x:
x*(65p) + 4x*(65p) + (x+3)*(65p) = £52.65
Simplifying the equation:
65x + 260x + 65x + 195 = 5265
390x + 195 = 5265
390x = 5070
x = 13
So, Andy bought 13 cakes, Betty bought 4x13 = 52 cakes, and Colin bought (13+3) = 16 cakes.

At the newest animated movie, for every 99 9 children, there are 44 4 adults. There are a total of 3939 39 children and adults at the movie. How many children are at the movie?
Answer:
27 children.
Step-by-step explanation:
We are told that at the newest animated movie, for every 9 children, there are 4 adults. There are a total of 39 children and adults at the movie.
We can see that number of children is proportional to number of adults. So we will use proportions to solve for number of children at the movie.
[tex]\frac{\text{Number of children}}{\text{Number of children + Adults}}=\frac{9}{4+9}[/tex]
[tex]\frac{\text{Number of children}}{\text{Number of children + Adults}}=\frac{9}{13}[/tex]
Let us substitute number of children and adults in our proportion.
[tex]\frac{\text{Number of children}}{39}=\frac{9}{13}[/tex]
Multiply both side of equation by 39.
[tex]39*\frac{\text{Number of children}}{39}=39*\frac{9}{13}[/tex]
[tex]\text{Number of children}=39*\frac{9}{13}[/tex]
[tex]\text{Number of children}=3*9[/tex]
[tex]\text{Number of children}=27[/tex]
Therefore, 27 children are at the movie.

Exponential functions exhibit exponential growth (or decay). What does this mean to the graphs of these functions?
Answer:
Option a is correct.
Exponential functions exhibit exponential growth (or decay) which mean the graph will rise or fall more dramatically than a polynomial graph
Step-by-step explanation:
An exponential function is in the form of [tex]y =ab^x[/tex] where a≠0 is a y-intercepts and b is a positive number other than 1, multiplier this base is constant , x is the independent variable and y is the dependent variable.
Exponential growth:
If b > 1 when x increases, y increases at a increasing rate .Exponential decay:
if b is between 0 and 1 i.e, 0 <b< 1 when x increases, y decreases at a increasing rate .therefore, the graph will rise or fall more dramatically than a polynomial graph

Two angles are supplementary. The measure of one angle is 4 times the measure of the other angle. What is the measure of the smaller angle
The measure of the smaller angle, when it is one-fourth the measure of the other supplementary angle, is 36 degrees.
The student is asking about the measures of two supplementary angles where one angle is four times the measure of the other angle. In Mathematics, supplementary angles are two angles whose sum is 180 degrees. Let's call the smaller angle 'x' and the larger angle '4x'. The equation we need to solve is:
x + 4x = 180
This equation simplifies to '5x = 180', meaning that 'x', the smaller angle, is equal to '180 / 5', which calculates to be 36 degrees. Therefore, the measure of the smaller angle is 36 degrees.

Identify the perimeter and area of a square with diagonal length 11in. Give your answer in simplest radical form. HELP PLEASE!!
Answer:
Perimeter = 22*sqrt(2)Area = 60.5 inchesDStep-by-step explanation:
Remark
You need 2 facts.
A square has 4 equal sides. It contains (by definition) 1 right angle but since we are not including and statement about parallel sides, it needs 4 right angles.That means you can use the Pythagorean Theorem.
If one side of a square is a then the 1 after it is a as well.
Formula
a^2 + a^2 = c^22a^2 = c^2Givens
c = 11Solution
2a^2 = 11^22a^2 = 121 Divide by 2a^2 = 121/2 Take the square root of both sidessqrt(a^2) = sqr(121/2) a = 11/sqrt(2) Rationalize the denominatora = 11 * sqrt(2)/[sqrt(2) * sqrt(2)]a = 11 * sqrt(2) / 2Perimeter
P = 4s
P = 4*11*sqrt(2)/2P = 44*sqrt(2)/2P = 22*sqrt(2)You don't need the area. The answer is D
Area
Area = s^2Area = (11*sqrt(2)/2 ) ^2Area = 121 * 2 / 4Area = 60.5For a square with a diagonal length of 11in, the side length is 11√2/2. The area of the square is then 60.5 square inches and the perimeter is 22√2 inches.
Explanation:To find the perimeter and area of a square with a given diagonal length, we need to firstly understand the relation between the diagonal and sides of the square. A square's diagonal divides it into two equal right triangles, and according to Pythagoras' theorem, the diagonal, being the hypotenuse in these right triangles, is equal to the square root of the sum of the squares of the sides. But since all sides of a square are equal, let's say the side length is 'a', then the diagonal would be 'a√2'.
Given that the diagonal length is 11in, we then have:
11 = a√2 or a = 11/√2
It's common to rationalize the denominator which gives: a = 11√2/2
Area of a square is a², therefore, Area = (11√2/2)² = 121/2 = 60.5 square inches.
The Perimeter of a square is 4a, therefore, Perimeter = 4 * (11√2/2) = 22√2 inches.
