Answer:

40 points

Step-by-step explanation:

32 points = 80% or 4/5

if you divide 32 by 4, you get 8+8+8+8=32

that means you need to add 8 to 32 to get the total number of points

Answer: The answer is A. (1, 4)

Step-by-step explanation:

Answer:

The combination formula is 8! / (8-5)! * 5!

= 8! / 3! * 5!

= 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1/ 3 * 2 * 1  * 5 * 4 * 3 * 2 * 1 (expand)

= 8 * 7 * 6 / 3 * 2 * 1 (5 * 4 * 3 * 2 * 1 cancels on both sides)

= 8 * 7 = 56 (3 * 2 * 1 = 6)

Answer:

x < 5.1

Step-by-step explanation:

Let's define:

Using Law of Sines we can find x, as follows:

10/sin(95°) = 8/sin(α)

sin(α) = sin(95°)*8/10

α = arcsin(0.8) = 53.13°

β = 180° - 95° - 53.13° = 31.87°

x/sin(β) = 10/sin(95°)

x = 10/sin(95°)*sin(31.87°)

x = 5.3

On the other hand, we know that the addition of the two shorter sides of a triangle must be greater than the long side of the triangle. Therefore:

8 + 5.3 > 3x - 2

Solving:

8 + 5.3 + 2 > 3x  

15.3/3 > x

5.1 > x

or

x < 5.1

The value of x from the given inequality is x < 5.1

Inequality expressions are expressions that are not equal to each other

Given the following variables;

Using the sine law to determine the value of x

10/sin(95°) = 8/sin(α)

sin(α) = sin(95°)*8/10

α = arcsin(0.8) = 53.13°

β = 180° - 95° - 53.13° = 31.87°

x/sin(β) = 10/sin(95°)

x = 10/sin(95°)*sin(31.87°)

x = 5.3

Also, using the rule that states that the addition of the two shorter sides of a triangle must be greater than the long side of the triangle. Hence;

8 + 5.3 > 3x - 2

8 + 5.3 + 2 > 3x  

15.3/3 > x

5.1 > x

x < 5.1

Hence the value of x from the given inequality is x < 5.1

Answer:

The error was in step 3

Step-by-step explanation:

The first two steps are correct, the property of addition of internal angles of a triangle that equal [tex]180^o[/tex] is properly used, Also the addition of supplemental angles to total  [tex]180^o[/tex] is also properly used.

In step 3. there is an error. Notice how it should have been done:

[tex]\angle m+\angle n +\angle o=180^o\\\angle o + \angle p = 180^o\\then:\\\angle m+\angle n +\angle o=180^o=\angle o+\angle p\\\angle m+\angle n +\angle o=\angle o+\angle p[/tex]

Step-by-step explanation:

Answer:

Use the quadratic formula

x = [-b  +- sqr root (b^2 - 4*a*c)] / 2a

x = [-3 +- sqr root (9 - 4*1*-7)] / 2

Answer:

[tex]M.A.D = 1[/tex]

Step-by-step explanation:

Given

9, 7, 6, 8, 7, 5

Required

Mean Absolute Deviation

The first step is to calculate the mean of the given data;

[tex]Mean = \frac{\sum{x}}{n}[/tex]

where x = 9, 7, 6, 8, 7, 5 and n = 6

[tex]Mean = \frac{9+ 7+ 6+ 8+ 7+ 5}{6}[/tex]

[tex]Mean = \frac{42}{6}[/tex]

[tex]Mean = 7[/tex]

Subtract mean (7) from each data

[tex]9 - 7 = 2\\7 - 7 = 0\\6 - 7 = -1\\8 - 7 = 1\\7 - 7 = 0\\5 - 7 = -2[/tex]

Return the absolute values of each

[tex]|2| = 2\\|0| = 0\\|-1| = 1\\|1| = 1\\|0| = 0\\|-2| =2[/tex]

Calculate mean of the above absolute values

[tex]Mean = \frac{\sum{x}}{n}[/tex]

[tex]Mean = \frac{2+0+1+1+0+2}{6}[/tex]

[tex]Mean = \frac{6}{6}[/tex]

[tex]Mean = 1[/tex]

Hence, the mean absolute deviation of the given data is 1

Step-by-step explanation:

The two situations above didn’t even mention letters. One situation mentioned carrot and broccoli out of 10 vegetables. The other situation mentioned Al, Bob and Carl out of a class of 30 students.

The number of letters (4) out of total letters (10) doesn’t matter because it wasn’t one of the two previously mentioned situations.

Answer:

(3, -7) and (1, 2) are solutions to the equation

Step-by-step explanation:

Simply replace the (x, y ) pair of values in the equation and see if the equality holds:

Pair (0, -8) :

9 (0) + 2 (-8) = -16  therefore this pair is NOT a solution of the equation

Pair (3, -7):

9 (3) + 2 (-7) = 27-14 = 13  therefore this pair IS a solution of the equation

Pair (1, 2):

9 (1) + 2 (2) = 9 + 4 = 13  therefore this pair IS a solution of the equation

Pair (4, -5):

9 (4) + 2 (-5) = 36 - 10 - 26  therefore this pair is NOT a solution of the equation

Answer:

Area = 25cm²

Step-by-step explanation:

Given

Length of a square = 4.89cm

Required

Estimate the area of the square

The question says that the length of the side of the square be approximated to 1 significant figure.

When 4.89cm is approximated, it gives 5cm.

At this point, the area of the square can be estimated.

Area = Length * Length

Area = 5cm * 5cm

Area = 25cm²

Hence, the estimated area of the square is 25cm²

Answer:

Step-by-step explanation:

Given

[tex]z(14x -2y)=7[/tex]

Required;

Solve for x, when

[tex]z(14x -2y)=7[/tex]

Divide both sides by z

[tex]\frac{z(14x -2y)}{z} = \frac{7}{z}[/tex]

[tex]14x -2y = \frac{7}{z}[/tex]

Add 2y to both sides

[tex]14x -2y + 2y= \frac{7}{z} + 2y[/tex]

[tex]14x = \frac{7}{z} + 2y[/tex]

Divide both sides by 14

[tex]\frac{14x}{14} = \frac{1}{14}(\frac{7}{z} + 2y)[/tex]

[tex]x = \frac{1}{14}(\frac{7}{z} + 2y)[/tex]

The above expression is the value of x when [tex]z\neq 0[/tex]

To solve for when z = 0, we simply substitute 0 for z

[tex]x = \frac{1}{14}(\frac{7}{z} + 2y)[/tex]

[tex]x = \frac{1}{14}(\frac{7}{0} + 2y)[/tex]

0 cant't divide any number; hence, from the above expression we conclude that

[tex]x = \ u\ n\ d\ e \ f\ i \ n\ e\ d[/tex]
