Answer:

K = 4 ; N = 106

Step-by-step explanation:

Given the following :

Source of VARIATION - SS - df - - MS - - - - - F

Between groups - 1,959.79 - 3 - - 653.26 - 21.16*

Error - - - - - - - - 3,148.61 - - - - 102 - - 30.86

Total - - - - - - - - - - - 5,108.41 - 105

The degree of freedom between group (treatment) (DFT) is obtained using the formula ;

K - 1, where k = number of groups observed

DFT = K - 1 ; From the ANOVA table, DFT = 3

3 = K - 1

3 + 1 = K

K = 4

To obtain sample size (N) :

Degree of freedom of Error (DFE) is the difference between the sample size and the number of groups observed.

DFE = N - K ; From. The table DFE = 102 ; K = 4

102 = N - 4

102 + 4 = N

N = 106

Answer:

B

Step-by-step explanation:

We see that the line intersects the y-axis at -1.  As a result, we need to choose an equation with -1, either B or C.  We see that the different is the slope.  For choice B, the slope is \(\frac{1}{3}\), meaning that every unit up equates to 3 blocks to the right.  Counting along the line, we see that this is correct.

a) He needs 500 g of sugar to make apple crumble for 16 people.

b) She needs 45 g of flour to make apple crumble for 2 people.

c) 500g of apples is enough to make apple crumble for 6 people.

The amounts for this problem are obtained according to the proportions given in the problem.

For 8 people, the amount of sugar needed is of 250 g. For 16 people, the  number of people doubles, hence the amount of sugar needed will also double, as follows:

2 x 250 = 500 g.

For 2 people, the amount of each item is divided by 4, hence the amount of flour needed is given as follows:

180/4 = 45 g.

The amount of apple needed per people is of:

700/8 = 87.5 grams.

For 6 people, the amount is given as follows:

6 x 87.5 = 525 grams.

Hence 500g of apples is enough to make apple crumble for 6 people.

What is the cost amount?

The cost of an asset to you often serves as its basis. The cost is the sum that you pay for it using money, debt, other goods, or services. Sales tax and other purchase-related costs are included in the price.

Here, we have

Given: A store sells oranges and apples. Oranges cost $1.00 each and apples cost $2.00 each. In the first sale of the day, 15 fruits were sold in total, and the price was $25.

We have to determine how many of each type of fruit were sold.

We, let the oranges be x.

let the apples be y.

x + y = 15...(1)

1x + 2y = 25...(2)

We subtract equation(2) from equation(1), we get

y = 10

Now we put the value of y in equation (1) and we get

x + 10 = 15

x= 5

Hence, a store sells 5 oranges and 10 apples.

Step-by-step explanation:

5% of 350 is 17.5

$350+$17.5=367.5

We can get equation B rom equation A by dividing through by 3

This is is one of the basic mathematical operation and the opposite of multiplication. It shows how many times the divisor is contained in the dividend

3 ( x +2 ) = 18 ____ A

x + 2 = 6 _____B

solving from A to B

3 ( x +2 ) = 18

dividing through by 3 gives

x + 2 = 6

x + 2 = 6

x = 4

substituting x = 4 into equation A

3 ( x +2 ) = 18

18 = 18

3 ( 4 +2 ) = 18

3 (6 ) = 18

18 = 18

The solution to the set of equation is consistent and shows that it can be solved to get x equal to 4 using the substitution method

The segment lengths are given as follows:

The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

The theorem is expressed as follows:

c² = a² + b².

In which:

Considering the geometric mean theorem, the triangle has bases of 7 and 14 - 7 = 7, hence the altitude BD is given as follows:

BD² = 7 x 7

BD² = 7²

BD = 7.

The segment BC is the hypotenuse of a right triangle of two sides with length 7, hence:

(BC)² = 7² + 7²

\(BC = \sqrt{2 \times 49}\)

\(BC = 7\sqrt{2}\)

Answer:

Angle Q is 51°

Angle R is 96°

(x=5 and the exterior angle is 84°)

Step-by-step explanation:

Exterior Angle Theorem says that angle that's outside the triangle (extend a side and see the angle between the side extension and the side) IS Equal to the sum of the two angles that are farther away.

17x - 1 = 33 + 10x + 1

Get all the x's on one side of the equation.

17x-10x - 1 = 33 + 10x-10x+1

7x - 1 = 33 + 1

7x - 1 = 34 add 1 to both sides

7x = 35 divide by 7

7x/7 = 35/7

x = 5

Not finished ! Find Angle Q

10x+1 = 10(5)+1= 51°

Angle PRQ is insidethe triangle. All the angles of a triangle add up to 180°

33° + 51° + R = 180°

84° + R = 180°

R = 96°

Consider the equation |x-4| = 5. This equation has two solutions since the distance of x from 4 on the number line can be 5 units in either direction, giving x = 9 or x = -1.

What is algebra?

Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas.

An absolute value equation is of the form |x| = a, where "a" is a positive number. The absolute value of a number is always non-negative, so the equation |x| = a has two possible solutions, x = a and x = -a.

However, there are three possible cases for how many solutions an absolute value equation could have:

One solution: This occurs when a=0. The only solution is x=0 because |0|=0.

Two solutions: This occurs when a > 0. The two possible solutions are x = a and x = -a, since |a| = a and |-a| = a. For example, the equation |x-3| = 2 has two solutions: x-3 = 2 or x-3 = -2, which gives x = 5 or x = 1.

No solutions: This occurs when a < 0. Since the absolute value of a number is always non-negative, an absolute value equation with a negative number on the right-hand side has no solutions. For example, the equation |x-3| = -2 has no solutions since -2 is negative.

The difference in the number of solutions is due to the nature of absolute values. The absolute value of a number represents the distance of the number from zero on the number line, so an absolute value equation can have two solutions when the distance is equal to a positive number, one solution when the distance is equal to zero, and no solution when the distance is less than zero.

For example, consider the equation |x-4| = 5. This equation has two solutions since the distance of x from 4 on the number line can be 5 units in either direction, giving x = 9 or x = -1.

Answer: Absolute value equations are important in situations where values cannot be negative, like measuring distance. For example, if you forget which floor your friend lives on and he tells you he's on the fourth floor, and you say you're two floors away, you could be on either the second or sixth floor. Absolute value inequalities are important in determining margins of error or tolerance, especially in manufacturing.

Step-by-step explanation:

When solving an absolute value equation, three possible scenarios could occur. The first scenario is when the absolute value expression equals a positive number. In this case, there will be two solutions, one positive and one negative. The second scenario is when the absolute value expression equals zero. In this case, there will be only one solution, which is zero. The third and final scenario is when the absolute value expression equals a negative number. In this case, there are no solutions, as the absolute value of any number is always non-negative.

The reason there are differences in the number of solutions for each case is due to the nature of absolute value. Absolute value always returns a non-negative value, regardless of the sign of the number inside the absolute value expression. Therefore, when the absolute value expression is positive, there are two possible solutions, one positive and one negative. When the expression equals zero, there is only one solution, which is zero. And when the expression is negative, there are no solutions, as there cannot be a negative absolute value.

Answer:

After the pumping, Container B is 11.8\%11.8% empty.

Step-by-step explanation:

The volume of water inside Container B equals the entire volume of Container A. The empty portion of Container B is equal to the entire volume of Container B minus the volume of water inside Container B. So the volume of empty space inside Container B is equal to 1570.7963-1385.44241570.7963−1385.4424 which equals 185.3539. The percent of Container B that is empty can be found by setting up a proportion with the entire volume of Container B: 11.8 %
