Answer:

I think what you got is correct

The percentage of incorrect problems is 25%.

Option D is the correct answer.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of problems = 20

Number of correct problems = 15

The number of incorrect problems.

= 20 - 15

= 5

The percentage of incorrect problems.

= 5/20 x 100

= 25%

Thus,

25% were incorrect problems

Answer:

[tex]x^{2}+y^{2}-x[/tex]

Step-by-step explanation:

combine like terms:

(3x²+2y²-3x) ₋ (2x²+y²- 2x)

3x² - 2x² = 1x² = x²

2y² - y² = 1y² = y²

(-3x) - (-2x) = -1x = -x

Answer:

10. y=-4x+3

12. y=[tex]\frac{1}{2}[/tex]x+3

Step-by-step explanation:

In order for a line to be perpendicular to another, their slopes must be opposite reciprocals.

1. Put the given equations into slope-intercept form. (y=mx+b)

2. Identify the opposite reciprocal of the original equations. (#10: -4 & #12: [tex]\frac{1}{2}[/tex])

3. Plug your given coords and opposite reciprocals into point-slope formula (y-y₁=m(x-x₁)) and simplify the expression to get your equation of the line.

Answer:

The probability that the value of the second die is higher than the first

[tex]P(E) = \frac{15}{36} = \frac{5}{12}[/tex]

Step-by-step explanation:

Explanation:-

In a single throw with two dice total number of sums = 6 X 6 = 36

Let 'E' be the event of the second die is higher than the first

Total number of cases

= {( 1,1), (1,2 )( 1,3), (1,4) , (1,5) ,(1,6)

  ( 2,1), (2,2 )( 2,3), (2,4) , (2,5),(2,6)

   ( 3,1), (3,2 )( 3,3), (3,4) , (3,5),(3,6)

( 4,1), (4,2 )( 4,3), (4,4) , (4,5),(4,6)

( 6,1), (6,2 )( 6,3), (6,4) , (6,5),(6,6)}

The favourable cases

Answer:

He can run 112 yards in 12 seconds

Step-by-step explanation:

Here, we want to know the number of yards he can run in 12 seconds

From the question, we are told that his running rate is 38 yards in 4 seconds

So the number of yards he can run in 12 seconds will be;

38 * 12/4

= 38 * 3 = 114 yards

Answer:

Option (a)

Step-by-step explanation:

This question is incomplete without statements; find the statements as followed,

a). Ricky's claim is incorrect since not all rotations that carry a square onto itself are multiples of 30 degrees.

b). Ricky's claim is incorrect since not all rotations that are multiples of 30 degrees carry a square onto itself.

c). Ricky's claim is correct since any rotation that carries a square onto itself is a multiple of 30 degrees.

d). Ricky's claim is correct since any rotation that is a multiple of 30 degrees carries a square onto itself.

Square ABCD will map onto itself when point A comes to B, C or D by a rotation about the center E with a multiple of measure of angle AEB.

m∠AEB = 90° [Diagonals of a square intersect each other at 90°]

In simpler words, if square ABCD is rotated 90° or it's multiple about the center E, square will overlap itself.

Therefore, Option (a) is correct.

Answer:

12.72 dollars per hour

Step-by-step explanation:

Her original money is $12 per hour. We know that 6% in a decimal is 0.06. But if we multiply 0.06 and $12, it would get an answer that is decreasing than increasing. So we can get this equation. 12+0.06*12. ( 12 dollars plus 6% of 12 dollars)  If we divide by 12, we get: 12( 0.06+1). 0.06+1=1.06. And 1.06*12 is 12.72 dollars per hour now.  I hope this helps your question!

Answer:

The answer is 6

Step-by-step explanation:

The highest common factor between the numbers is 6.

The greatest common factor is the largest positive number which can be divided into given numbers evenly.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the two numbers are 90 and 48. The highest common factor will be calculated as,

90 = 2 x 3 x 3 x 5

48= 2x2x2x2x3

The common numbers are 2 x 3  = 6

Therefore, the highest common factor between the numbers is 6.

Set the two expressions equal to one another and solve for x

22x = 12x+9

22x-12x = 9

10x = 9

x = 9/10

x = 0.9

Assuming x is the number of items sold, then it is not possible to have the same amount earned for the two days. This is because we cannot sell 0.9 of an item. So it appears it is not possible to earn the same amount each day.

Answer:

B. The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5

Step-by-step explanation:

It is a quadratic and in the form:

f(x) = a(x-h)^2 + k

In this case a = 5, and if a is greater than  1, then the parabola is vertically stretched. It is not vertically compressed because a is not less than 1.

h and k are irrelevant because there are no horizontal or vertical shifts in the graph.

Therefore, when compared to f(x) = x^2, the graph has only been vertically stretched by a factor of 5.

the graph of g(x) is the graph of f(x) vertically stretched by a factor of 5
