a is answer correct i think

Step-by-step explanation:

Answer:

(a)Dependent

(b)Both

(c)Independent

Step-by-step explanation:

a) When selections are made without replacement, the second(next) outcome is dependent of the first(previous) outcome. Therefore, we subtract one from the draw on the total.

(b)The probability of Event A and Event B is the multiplication of the probability of event A and the probability of event B. Events A and B can either be dependent or independent.

(c)When selections are made with replacement, the next outcome is independent of the previous outcome. Therefore, we say that the two events are independent.

Step-by-step explanation:

Answer:

y = 50 x = 10.

Step-by-step explanation:

Let's solve for y first.

We know the line angle 80 and angle 2y-5 is on a 180 degree line.

Now we can do our work:

180 - 85 = 95

2y - 5 = 95

95 + 5 = 100

100 ÷ 2 = 50

2(50) - 5 = 95?

The equation is correct, therefore y = 50.

No we do the same thing for the other angles, 90 and 3x + 55.

Again, 180 line.

180 - 95 = 85

3x + 55 = 85

85 - 55 = 30

30 ÷ 3 = 10

3(10) + 55 = 85?

The equation is correct therefore x = 10.

Thus, y = 50 and x = 10.

Answer:

0.50

Step-by-step explanation:

Do the opposite of addition

So 1.25 - 0.75

The solution to the equation 1.25 = 0.75 + r for r is r = 0.5

From the question, we have the following parameters that can be used in our computation:

1.25 = 0.75 + r

Add -0.75 to both sides of the equation

so, we have the following representation

-0.75 + 1.25 = 0.75 + r + -0.75

Evaluate the like terms on the right hand side

This gives

-0.75 + 1.25 = r

Evaluate the like terms on the left hand side

This gives

0.5 = r

Rewrite as

r = 0.5

Hence. the solution is 0.5

Answer:

Jo should have rounded the divisor to -6.

Explanation:

When rounding, a number with a decimal value below 0.5 rounds down and a number with a decimal value of 0.5 and greater gets rounded up. 0.3 is less than 0.5 which means -6.03 is closer to -6 than -7 and should have been rounded to -6 instead.

Step-by-step explanation:

simple division :)))

The way you can tell if the graph is going to cross the x-axis or just touch the x-axis is by looking at the power of factor

(x-5)^3 has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis

(x+2)^2 has the power of 2 which is an EVEN number. An Even power means that the graph will touch the x-axis

To find where it will touch the axis set the factor equal to zero and solve .

(x + 2) = 0

Subtract 2 from both sides

x=-2

Step-by-step explanation:

Midsegments of a triangle and a trapezoid are alike, because their endpoints, are the midpoints of the sides they touch. ... whereas, the length of a midsegment of a triangle is base/2.

The one difference in midsegments for triangles versus midsegments for trapezoids Midsegments of triangles and trapezoids are different because we can draw 3 of them in triangles, but only one in trapezoids.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

A trapezoid, commonly referred to as a trapezium, is a quadrilateral or a polygon with four sides. It has a set of parallel opposing sides and a set of non-parallel sides. The bases and legs of the trapezoid are known as the parallel and non-parallel sides, respectively.

If a line through the midpoint of a leg of a trapezoid is parallel to its bases, then the line passes through the midpoint of the other leg.

The midsegment of a trapezoid is half the length of the two parallel sides.

The midsegment theorem states that a line segment connecting the midpoints of any two sides of a triangle is parallel to the third side of a triangle and is half of it.

Answer:

Profit P(x) = 53x-12 and On selling 20 video games profit will be 1048.

Step-by-step explanation:

In the given question functions are Revenue function : R(x) = 60x and Cost function : C(x) = 12+7x  for the sale of x video games

As we know profit = sale price - cost price

Therefore P(x) = R(x) - C(x)

Or P(x) = (R-C)x = 60x - (12+7x)

P(x) = 60x -12 - 7x

P(x) = 53x -12

Now the profit on selling 20 video games will be

P(20) = 53×20 -12 = 1060 -12 = 1048.

Answer:

Function f(x) is positive for the values x ≤ -6 and x ≥ -2 and negative in the interval -6 ≤ x ≤ -2.

Step-by-step explanation:

As given in the graph,

Given function is a quadratic function, f(x) = (x + 2)(x + 6)

With x-intercepts of the function, x = -6 and -2

Graph below the x-axis represents the negative values of the function.

Graph above the x-axis represents the positive values of the function.

Therefore, function f(x) is positive for the values x ≤ -6 and x ≥ -2 and the function is negative in the interval -6 ≤ x ≤ -2.

The quadratic equation is not factorized completely. The given factors are prime factors. Option A is correct.

A mathematical quantity is factorized when it is expressed as multiples of smaller units of closely related quantities.

Factorization is the breakdown of an integer into smaller numbers that, when multiplied together, yield the original, considered number. Factors of those regarded as integers are those who make up an integer.

When all those factors are prime numbers, this is known as prime factorization. In other words, prime factorization expresses an integer in terms of prime multiples.

Answer:

Option D.

Step-by-step explanation:

From the given graph it is clear that it is a parabola along to the x-axis.

Vertex form of a parabola along the x-axis is

[tex]x=a(y-k)^2+h[/tex]

where, (h,k) is vertex.

From the graph it is clear that the vertex of the parabola is (4,-3). So, substitute h=4 and k=-3 in the above equation.

[tex]x=a(y-(-3))^2+(4)[/tex]

[tex]x=a(y+3)^2+4[/tex]   ...(1)

The graph passing through (1,-2), so substitute x=1 and y=-2 in the above equation.

[tex]1=a(-2+3)^2+4[/tex]

[tex]1-4=a(1)^2[/tex]

[tex]-3=a(1)^2[/tex]

Substitute a=-3 in equation (1).

[tex]x=-3(y+3)^2+4[/tex]

Therefore, the correct option is D.

Answer:

1.) m∠1 = 63 degree

m∠3 = 63 degree

m∠4 = 117 degree

m∠2 = 117 degree

2.) m∠1 = 70 degree

m∠3 = 70 degree

m∠4 = 110 degree

m∠2 = 110 degree

Step-by-step explanation:

Given that

1.) m∠2 = 117°.

In the figure, m∠1 is vertically opposite to m∠3, and m∠4 is vertically opposite to m∠2

Therefore, m∠2 = m∠4 = 117° ( because vertically opposite angle are equal)

Also, the sum of angles at a point is equal to 360 degrees

m∠2 + m∠4 = 234°

Take 234 away from 360. That is,

360 - 234 = 126

126/2 = 63 degrees.

Therefore, m∠1 = m∠3 = 63°

2.) If m∠2 + m∠4 = 220°

Subtract 220 from 360 since the sum of angles at a point is equal to 360 degrees

360 - 220 = 140

Divide 140 by 2 and also 220 by 2 to get

140/2 = 70 and 220/2 = 110

Therefore,

m∠1 = 70 degree

m∠3 = 70 degree

m∠4 = 110 degree

m∠2 = 110 degree
