Answer:

C.) they both got two more questions correctly than Chris did.

Step-by-step explanation:

brian got 14 more right than chris

Chris got 2 less than damien

brian and damien both got 18/20 correct, chris got 16 right

a. Let A be the matrix of unit prices for Supplier A and B be the matrix of unit prices for Supplier B:

A =

[8 9 6 24 4]

[12 12 6 18 4]

B =

[9 12 6 18 4]

[12 7 6 18 4]

Let D be the matrix of department orders:

D =

[6 10 4 3 5]

[7 4 2 2 3]

[4 0 5 1 0]

[0 5 3 4 5]

To get the comparative costs for each department for the products from the two suppliers, we need to multiply D by the element-wise difference between A and B:

(A - B) =

[-1 -3 0 6 0]

[0 5 0 0 0]

Comparative costs = D * (A - B) =

[-8 -27 0 54 0]

[-5 -23 0 0 0]

[-4 0 0 6 0]

[0 -15 0 24 0]

b. To find the cost of Department 3's supplies if they buy from Supplier A, we need to multiply the third row of D by the third row of (A - B):

[4 0 5 1 0] * [0 0 0 6 0] = 0 + 0 + 0 + 6 + 0 = 6

So the cost of Department 3's supplies if they buy from Supplier A is $6.

c. To find the total cost to buy products from each supplier, we need to multiply D by A and B and then sum the elements in each resulting matrix:

Total cost from Supplier A = sum(D * A) = $487

Total cost from Supplier B = sum(D * B) = $480

So the company should make the purchase from Supplier B as it will cost them less.

Answer:

1/6 probability

Step-by-step explanation:

He only got one even number out of 6 attempts, so its a one in six 1/6.

The cost of each entity: each pen is $\(1.75\), each folder is $\(2.50\), and each notebook is $\(1.75\).

Let's assign variables to the costs of each supply:

Let the cost of each pen be P dollars.

Let the cost of each folder be F dollars.

Let the cost of each notebook be N dollars.

According to the given information, we can form the following equations:

For Shane:

\(4P + 3F + 2N = 12.25 (Equation \ 1)\)

For Cheryl:

\(4F + 6N = 22 (Equation \ 2)\)

For Isaiah:

\(2P + F + 3N = 10.25 (Equation \ 3)\)

To solve this system of equations, we can use substitution or elimination method.

Using the elimination method, let's multiply Equation 2 by 2 and Equation 3 by 4 to eliminate F:

\(8F + 12N = 44 (Equation \ 4)\\8P + 2F + 12N = 41 (Equation \ 5)\)

Now, subtract Equation 4 from Equation 5 to eliminate F:

\(8P + 2F + 12N - (8F + 12N) = 41 - 44\\8P - 6F = -3\)

Simplifying further, we have:

\(8P - 6F = -3 (Equation \ 6)\)

Now, let's multiply Equation 1 by 4 and Equation 3 by 3 to eliminate N:

\(16P + 12F + 8N = 49 (Equation \ 7)\\6P + 3F + 9N = 30 (Equation \ 8)\)

Now, subtract Equation 8 from Equation 7 to eliminate N:

\(16P + 12F + 8N - (6P + 3F + 9N) = 49 - 30\\10P + 9F - N = 19\)

Simplifying further, we have:

\(10P + 9F - N = 19 (Equation \ 9)\)

Now we have a system of equations consisting of Equation 6, Equation 9, and Equation 2:

\(8P - 6F = -3 (Equation \ 6)\\10P + 9F - N = 19 (Equation \ 9)\\4F + 6N = 22 (Equation \ 2)\)

To find the values of P, F, and N, we can solve this system of equations using any suitable method, such as substitution or elimination.

The given statement "For a sample with a standard deviation of s = 8, a score of x = 42 corresponds to z = -0.25. The mean for the sample is m = 40." is False because the calculated z-score does not match the given value.

To calculate the z-score, we use the formula z = (x - m) / s, where x is the score, m is the mean, and s is the standard deviation. Substituting the given values, we have z = (42 - 40) / 8 = 0.25. However, the given statement states that the z-score is -0.25, which is incorrect. Therefore, the statement is false.

The correct z-score for x = 42 with a mean of m = 40 and standard deviation of s = 8 is 0.25, not -0.25.

the measure of the smallest angle of ΔDEF is approximately 41.41°.

How to solve the question?

In ΔDEF, DM is a median and M is on EF. Additionally, DM = EF, and DL is an angle bisector of ∠EDF, L is on EF, and m∠DLF = 64°. We need to find the measure of the smallest angle of ΔDEF.

Since DM is a median, it divides EF into two equal parts, EM and MF. Thus, EM = MF = DM/2 = EF/2.

Let x be the measure of ∠EDF. Then, we know that ∠EDM = ∠FDM = 90° because DM is a median.

Using the angle bisector theorem, we know that DL/EL = DF/EF. Since DL is an angle bisector, we also know that ∠DLE = ∠ELF = x/2. Therefore, we have:

DL/EL = DF/EF

DL/(EF/2) = DF/EF

DL = DF/2

Now, we can use the Law of Cosines in ΔDEF to find DF in terms of x:

DF² = DE² + EF² - 2(DE)(EF)cos(x)

DF² = DM² + MF² - 2(DM)(MF)cos(x)

DF² = (EF)²/4 + (EF)²/4 - (EF)²cos(x)

DF² = (EF)²/2 - (EF)²cos(x)

Since DL = DF/2, we have:

DL² = (EF)²/8 - (EF)²cos(x)/4

Using the angle bisector theorem again, we know that EL/FL = DE/DF. Since DL = DF/2, we also know that FL = EF - DL = EF/2. Therefore, we have:

EL/EF - EL/2 = DE/DF

EL/EF - EL/(2DL) = DE/DF

EL/EF - EL/(EF/4) = DE/DF

EL = EF(DE/DF)/3

Now, we can use the Law of Cosines again in ΔDEL to find DE in terms of x:

DE² = DL²+ EL² - 2(DL)(EL)cos(x/2)

DE² = (EF)²/8 - (EF)^2cos(x)/4 + [EF(DE/DF)/3]² - 2(DL)(EF(DE/DF)/3)cos(x/2)

DE² = (EF)²/8 - (EF)^2cos(x)/4 + (EF)²(DE/DF)^2/9 - (EF)(DE/DF)(EF/6)cos(x/2)

Since DM = EF, we have DE = DM - EM = EF/2 - EF/4 = EF/4. Thus, we can substitute this into the equation above and simplify:

(EF/4)²= (EF)²/8 - (EF)^2cos(x)/4 + (EF)^2(DE/DF)²/9 - (EF)(DE/DF)(EF/6)cos(x/2)

(EF)²/16 = (EF)²/8 - (EF)²cos(x)/4 + (EF)²(DE/DF)²/9 - (EF)(DE/DF)(EF/6)cos(x/2)

0 = (EF)²/72 - (EF)²cos(x)/4 + (EF)²(DE/DF)²/9 - (EF)(DE/DF)(EF/6)cos(x/2)

Now, we can substitute DL = DF/2 = (EF/4)/2 = EF/8 and EL = EF(DE/DF)/3 = EF(DE)/(3EF/4) = 4DE/3 into the equation above and simplify:

0 = (EF)²/72 - (EF)²cos(x)/4 + (EF)²(DE/DF)²/9 - (EF)(DE/DF)(EF/6)cos(x/2)

0 = (EF)²/72 - (EF)²cos(x)/4 + (EF)^2(DE/DF)²/9 - (EF/8)(4DE/3)(EF/6)cos(x/2)

0 = (EF)²/72 - (EF)²cos(x)/4 + (EF)²(DE/DF)²/9 - (EF²/72)cos(x/2)

0 = (EF)²/72 - (EF)²cos(x)/4 + (EF)²(DE/DF)²/9 - (EF)²cos(x/2)/18

Simplifying this equation, we get:

cos(x)/4 - cos(x/2)/18 = (EF)²/72 - (EF)²(DE/DF)²/9

Now, we can substitute DE = EF/4 and DF = EF/2 into the equation above and simplify:

cos(x)/4 - cos(x/2)/18 = (EF)²/72 - (EF)²/144

cos(x)/4 - cos(x/2)/18 = (EF)²/144

We know that cos(x) is negative because x is the measure of the smallest angle of ΔDEF, so we can take the absolute value of both sides of the equation:

|cos(x)/4 - cos(x/2)/18| = (EF)²/144

Since 0° < x < 180°, we know that cos(x/2) > cos(x), so we can simplify further:

cos(x/2)/18 - cos(x)/4 = (EF)²/144

Now, we can substitute the given value of ∠DLF = 64° into the equation above and solve for EF:

cos(32°)/18 - cos(128°)/4 = (EF)^2/144

0.0289 - (-0.2113) = (EF)²/144

0.2402 = (EF)²/144

EF = √(0.2402*144)

EF ≈ 4.8044

Finally, we can use the Law of Cosines in ΔDEF to find x:

cos(x) = (DE² + EF² - DF²)/(2(DE)(EF))

cos(x) = (EF²/16 + EF² - EF²/4)/(2(EF/4)(EF))

cos(x) = 3/4

x = arccos(3/4)

x ≈ 41.41°

Therefore, the measure of the smallest angle of ΔDEF is approximately 41.41°.

Answer:

The answer is "Option A"

Step-by-step explanation:

In point A:  

Rolling an indivisible prime number:  

The 2 can be moved just 1 way (1,1)  

The 3 can be moved two different ways (1,2) or (2,1)  

The 5 can be moved four different ways (1,4) or (2,3) or (3,2) or (4,1)  

The 7 can be moved six different ways (1,6) or (2,5) or (3,4) or (4,3) or (5,2) or (6,1)  

The 11 can be moved two different ways (5,6) or (6,5)  

There are 26 approaches to move two dice at a time.  

The likelihood of rolling an indivisible number is: \(=\frac{(1 + 2 + 4 + 6 + 2)}{36} =\frac{15}{36}\)

Because rolling an indivisible number is worth 15 focuses, the normal worth is \((\frac{15}{36}) \times 15 = 6.25\)

In point B:

When the rolling is a numerous of 3:  

The 3 can be moved two different ways (1,2) or (2,10  

The 6 can be moved five different ways (1,5) or (2,4) or (3,3) or (4,2) or (5,1)  

The 9 can be moved four different ways (3,6) or (4,5) or (5,4) or (6,3)  

The 12 can be moved just 1 way (6,6)  

The likelihood of rolling a numerous of 3 will be:\(= \frac{(3 + 6 + 9 + 12)}{36} = \frac{12}{36}\)

because the rolling in the various of 3 is worth 12 focuses, the normal worth is\((\frac{12}{36}) \times 12 = 4\)

The vertex of the parabola y = f(x + 1) is (1, -1).

To find the vertex of the parabola given by the equation y = f(x + 1), we need to determine the effect of the transformation on the vertex coordinates.

The vertex form of a parabola is given by y = a(x - h)^2 + k, where (h, k) represents the vertex coordinates.

In the given equation, y = f(x + 1), we can see that the transformation is a horizontal shift of 1 unit to the left. This means that the new vertex will be located 1 unit to the left of the original vertex.

Given that the original vertex is (2, -1), shifting 1 unit to the left would result in a new x-coordinate of 2 - 1 = 1. The y-coordinate remains the same.

Therefore, the vertex of the parabola y = f(x + 1) is (1, -1).

Myra will paint approximately 213.52 square

centimeters

on the cylindrical pillar.

To determine how many square centimeters will be painted on the cylindrical pillar, we need to calculate the

surface area

of the cylinder. The formula for the surface area of a cylinder is given by:

S = 2πrh + 2πr^2

where S is the surface area, r is the

radius

, and h is the

height

.

In this case, the radius of the pillar is 2 cm and the height is 15 cm. We can substitute these values into the formula to find the surface area:

S = 2 * 3.14 * 2 * 15 + 2 * 3.14 * 2^2

Simplifying the expression:

S = 6.28 * 2 * 15 + 12.56 * 4

S = 188.4 + 50.24

S = 238.64 square centimeters

It's important to note that the

formula

for the surface area of a cylinder includes the areas of both the curved surface (2πrh) and the top and bottom circles (2πr^2). Since Myra is painting the entire pillar, including the top and bottom, we need to consider both of these areas in our calculation.

Using the value of π as 3.14, we have found that the surface area of the cylindrical pillar to be painted is approximately 238.64 square centimeters.
