Mary used 66 pounds of type A coffee and 82 pounds of type B coffee to make a total of 148 pounds of the blend, with a total cost of $694.20.

Let's assume Mary used x pounds of type A coffee and (148 - x) pounds of type B coffee.

The cost of type A coffee is $5.30 per pound, so the cost of the type A coffee used is 5.30x.

The cost of type B coffee is $4.20 per pound, so the cost of the type B coffee used is 4.20(148 - x).

According to the given information, the total cost of the blend is $694.20. Therefore, we can set up the equation:

5.30x + 4.20(148 - x) = 694.20

Simplifying and solving for x

5.30x + 621.60 - 4.20x = 694.20

1.10x = 72.60

x = 66

Mary used 66 pounds of type A coffee. Therefore, she used (148 - 66) = 82 pounds of type B coffee.

Mary needs a minimum of 4 US coins to ensure she can make change for any amount of money from one cent to 99 cents.

To cover all possible amounts from one cent to 99 cents, Mary needs coins that can represent different values. The US coins available for this purpose are pennies (1 cent), nickels (5 cents), dimes (10 cents), and quarters (25 cents).

To find the minimum number of coins needed, we should select the coins with the highest denominations first. In this case, we can use the following approach:

1. Start with a quarter (25 cents). This coin alone can cover any amount up to 25 cents.

2. Add a dime (10 cents) to cover amounts up to 35 cents.

3. Add a nickel (5 cents) to cover amounts up to 40 cents.

4. Finally, add a penny (1 cent) to cover amounts up to 41 cents.

With these four coins (quarter, dime, nickel, and penny), Mary will be able to make change for any amount of money from one cent to 99 cents. This combination ensures that she has the necessary denominations to represent all possible amounts within that range.

Therefore, the constant a is -48/13 and the constant b is -32/13, such that vector z is orthogonal to both vectors x and y.

To show that vectors x and y are orthogonal, we need to verify if their dot product is equal to zero. Let's calculate the dot product of x and y:

x · y = (-2)(3) + (3)(2) + (0)(4)

= -6 + 6 + 0

= 0

Since the dot product of x and y is equal to zero, we can conclude that vectors x and y are orthogonal.

b) To find the constants a and b such that vector z is orthogonal to both vectors x and y, we need to ensure that the dot product of z with x and y is zero.

First, let's calculate the dot product of z with x:

z · x = (a)(-2) + (b)(3) + (4)(0)

= -2a + 3b

To make the dot product z · x equal to zero, we set -2a + 3b = 0.

Next, let's calculate the dot product of z with y:

z · y = (a)(3) + (b)(2) + (4)(4)

= 3a + 2b + 16

To make the dot product z · y equal to zero, we set 3a + 2b + 16 = 0.

Now, we have a system of equations:

-2a + 3b = 0 (Equation 1)

3a + 2b + 16 = 0 (Equation 2)

Solving this system of equations, we can find the values of a and b.

From Equation 1, we can express a in terms of b:

-2a = -3b

a = (3/2)b

Substituting this value of a into Equation 2:

3(3/2)b + 2b + 16 = 0

(9/2)b + 2b + 16 = 0

(9/2 + 4/2)b + 16 = 0

(13/2)b + 16 = 0

(13/2)b = -16

b = (-16)(2/13)

b = -32/13

Substituting the value of b into the expression for a:

a = (3/2)(-32/13)

a = -96/26

a = -48/13

Use the midpoint formula

M (5-11/2; 7-6/2)

M (-3; 1/2)

X-coordinate is -3

Answer:

x- coordinate = 8

Step-by-step explanation:

The x- coordinate of the midpoint is the average of the x- coordinates of the 2 endpoints, that is

\(\frac{5+11}{2}\) = \(\frac{16}{2}\) = 8 ← x- coordinate of midpoint

Answer:

8 x 3 = 24. 24/5 is greater than 4 so they must order 5 pizzas.

The average length encoding of a letter for a Huffman code of the letters and their given frequencies will be 245.

We have,

Frequencies:

a = 0.15 = 15,

b = 0.25 = 25,

c = 0.20 = 20,

d = 0.35 = 35,

e = 0.05 = 5,

So,

Now,

According to the question,

We will make Huffman tree,

i.e.

a = 0.15 = 15,

b + c = 25 + 20 = 45

d + e = 35 + 5 = 40,

Now,

a + b + c + d + e = 100

So,

a = 11 = 2 digits

b = 101 = 3 digits

c= 100 = 3 digits

d= 01 = 2 digits

e= 00 = 2 digits

And,

We know that,

Total bits required to represent Huffman code = 12.

So,

Now,

The average code length = a * 2 digits + b * 3 digits + c * 3 digits + d * 2 digits + e * 2 digits

i.e.

The average code length = 15 × 2 + 25 × 3 + 20 × 3 + 35 × 2 + 5 × 2

On solving we get,

The average code length = 245

Hence we can say that the average length encoding of a letter for a Huffman code of the letters and their given frequencies will be 245.

The significance of the slope in regression can be determined by conducting a hypothesis test

The slope of the regression line in a regression analysis shows how  dependent variable changes as the independent variable increases by a unit. A hypothesis test on a slope coefficient, commonly referred to as the beta coefficient or the regression coefficient, can be used to ascertain the significance of the slope. The slope coefficient is compared to a null hypothesis value of zero in the hypothesis test.

The null hypothesis is rejected and it is determined that there is a significant association between the independent and dependent variables if the p-value for the slope coefficient is less than the significance threshold. Therefore, slope is not equal to zero and there is an association amongst changes in the independent variable and those in the dependent variable.

Step-by-step explanation:

Sorry

Equation 1: x + y = $38

Equation 2: x = y + $6

Replace x in the first equation with the second equation :

y + 6 + y = 38

Simplify:

2y + 6 = 38

Subtract 6 from both sides:

2y = 32

Divide both sides by 2:

Y = 16

Now you know y, the cost of the jacket is $16

The shoes were $6 more so 15 + 6 = $22

Jacket cost $16

Shoes cost $22

Shoes: $22

Jacket: $16

Divide 38 by 2, which is 19

take away half of 6, which is 3.

Take 3 from 19, resulting in 16 which is your jacket

Add 3 to 19, resulting in 22 which are your shoes

The rate of the given situation will be 2 inches per minute.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

The distance is a one-seventh inch and the time is one-fourteenth minutes. Then the rate as a unit rate is given as,

Rate = (1/7) / (1/14)

Rate = (1/7) x (14/1)

Rate = 14/7

Rate = 2 inches per minute

Step-by-step explanation:

The class that lost the most pencils overall based on the data displayed is D. Mr. Johnson's class; it has a wide spread in the data

The answer is Mr. Johnson's class. The median is the middle value in a set of data. In Mr. Johnson's class, the median is 11 pencils. This means that half of the students in his class lost 11 or fewer pencils, and half of the students lost 11 or more pencils.

In Mr. Simpson's class, the median is 14.5 pencils. This means that half of the students in his class lost 14.5 or fewer pencils, and half of the students lost 14.5 or more pencils.

Since the median for Mr. Johnson's class is lower than the median for Mr. Simpson's class, we can conclude that Mr. Johnson's class lost more pencils overall.

Answer:

C

Step-by-step explanation:

To find the equilibrium price, we need to determine the price at which the quantity demanded is equal to the quantity supplied. In other words, we need to find the price where D(p) = S(p).

Given the demand function D(p) = 1628 - 16p and the supply function S(p) = -4 + 8p, we can set them equal to each other:

1628 - 16p = -4 + 8p

Simplifying the equation, we combine like terms:

24p = 1632

Dividing both sides by 24, we find:

p = 68

Therefore, the equilibrium price is $68. At this price, the quantity demanded (D(p)) and the quantity supplied (S(p)) are equal, resulting in a market equilibrium.
