The probability that a ball is not red is 3/5 and the probability that the ball is red or white is 2/3 .

Mathematical descriptions of the likelihood that an event will happen or that a proposition is true are dealt with in the discipline of mathematics known as probability.

In the given question there are  6 red balls, 4 white balls, and 5 blue

balls.

Total number of balls = 6+4+5 = 15 balls (sample space)

Red balls = 6

Not red balls = 15 - 6 = 9

Probability that the ball is red = 9/15 = 3 /5

Red and white balls = 6 + 4 =10

Probability that the ball is red or white = 10 / 15 = 2 / 3

Hence the probability that a ball is red or white is 2 / 3.

Marie should buy the bag with green apples as it has more weight hence it will have more apples eventually making her pie tastier

Comparison: When we compare, we look for similarities among the characteristics of other items or objects. Mathematicians use the concept of comparing and ranking numbers to identify the smaller and larger numbers and to determine whether they should be arranged in ascending or descending order.

Weight of bag with green apples = 4.75 pounds

Weight of bag with red apples = 4.54 pounds

Since the bag with green apples weighs heavier and contains more apples overall, Marie should purchase it because it will make her pie taste better.

Step-by-step explanation:

Answer:

Part a: x + 17 = 52    Part b: He should guess the number 35.

Step-by-step explanation:

In the equation, x stands for the number he has to guess. He is given the clue, "17 more than the number is 52." Therefore x + 17 = 52. Another equation you could use is 52 - 17 = x. This equation would be used to solve the problem. 52 - 17 = 35

The equation of the line passing from found as y = 5.

The formula for finding the slope is;

m = Δy/Δx

Where, m is the slope

The given equation of line is;

x = 3 comparing it with standard form of equation;

y = mx + c

As, the equation is a straight line passing parallel to x axis, the slop of line x = 3 is ∞.

Thus, m₁ =  ∞.

Now, let the slops of the line passing from (-2, 5) is m₂,

The, as both line are perpendicular.

Thus,

m₁ x m₂ = -1

m₂ = -1/∞

m₂ = 0

The equation of line is found by

y - y₁ = m₂(x - x₁)

Put the values;

y - 5 = 0(x + 2)

y = 5

Based on the interval, the average rate of change of the function is 4.0

The graph that completes the question is added as an attachment

From the graph, we can see  that the equation of the graph is a quadratic equation

Also, from the question:

We have the interval to be:

The interval is given as

x = -4 to x = 2

This can be represented as

(a, b) = (-4, 2)

From the attached graph, we have

f(-4) = 22

f(2) = -2

The estimate of the average rate of change f is calculated as(to one decimal place)

Rate = [f(b) - f(a)]/[b - a]

Substitute the known values in the above equation

This gives

Rate = [f(2) - f(-4)]/[2 + 4]

Substitute the known values in the above equation

So, we have

Rate = [-2 - 22]/[2 + 4]

Evaluate

Rate = -4.0

Answer:

Let width of rectangle be x cm.

Width = x cm

Length = 4x cm

Area of rectangle = length x width

4x × x = 144

4x² = 144

x² = 144 ÷ 4 = 36

x = √36 = 6

Width = 6 cm

Length = 6 × 4 = 24cm

Perimeter = 6 + 24 + 6 + 24 = 60 cm

The current price index is mathematically given as,$538.194

By increasing the ratio of the current value to the reference value by 100, one can determine the index value.

Given that the current cost of gasoline is $3.10 per gallon. we need to find the current price index number, using the 1975 price of 56.7 cents as the reference value.

In regard to this issue, we have that:

Current value = $3.10

Reference value: $0.576

Typically, the mathematical formula for the Index price is,

I = (3.10/0.576) x 100

I= $538.194

The measure of the angle is 1.0 when rounded to one decimal places.

If one of the triangle's angles is 90 degrees, the triangle is said to have right angles. The triangle with a right angle is known as a right triangle because a right angle is 90 degrees. Using the Pythagorean rule, it is simple to understand how the different sides of this triangle relate to one another. The greatest side of a right angle is known as the hypotenuse, and it is opposite the right angle. In addition, the right triangles are categorized as isosceles right triangles and scalene right triangles based on the other angle values. Pythagorean triples are another name for the right triangle's side lengths, which include 3, 4, and 5.

Given that : right triangle, we're provided the hypotenuse and the leg next to. We can use the cosine ratio to determine :

Cosθ =[tex]\frac{adjacent}{hypotenuse}[/tex]

Plug in the given information

Cosθ =[tex]\frac{4}{7}[/tex]

Use the inverse cosine ratio

We are asked to solve for a number such that:

Twice that number plus 4 equals 6

Which can be written in math terms as:

2 x + 4 = 6

Now we proceed to isolate the unknown in steps.

First we subtract 4 from both sides:

2 x + 4 - 4 = 6 + 4

we combine like terms:

2 x = 10

Now we divide both sides by 2 so as to cancel the factor 2 that accompanies "x":

2 x / 2 = 10/ 2

perform the indicated operations:

x = 5

The number of chips and drinks are 46 chips and 56 drinks respectively.

Let the number of drinks be d.

Let the number of chips be c.

From the information, he works at a football concession stand selling drinks for $2 and bags of chips for $3 and he makes a total of $246 and sells a total of 100 drinks and bags of chips.

This will be:

c + d = 100 ........ i

2d + 3c = 246 ........ ii

From equation i, c = 100 - d

Substitute this into equation ii

2d + 3c = 246

2d + 3(100 - d) = 246

2d + 300 - 3d = 246

Collect like terms

2d - 3d = 246 - 300

-d = -54

d = 54

Number of drinks = 54

Since c + d = 100

c + 54 = 100

c = 100 - 54 = 46

See explanation below

Explanation:

From the question, we are told line TV is perpendicular to line US.

This means the point which they intersect has an angle of 90°.

We are also told line TV bisects STU.

For a line to bisect an angle, it means it divided the angle into two equal parts.

When line TV bisects STU, it divided it into angle STR and angle UTR

Hence, ∠STR = ∠UTR

Also line SU and line and line VT intersect to give vertical angles.

Angle R and the angle opposite it are vertical angles.

Vertical angles are equal.

The angle with 90° and the angle opposite it is also a vertical angle.

you can see from the illustration. The two angles opposite each other are equal to 90°.

Since angle on a straight line = 180°

angle R + 90° = 180°

angle R = 180-90

angle R = 90°

All the 4 angles that result from the intersection line VT and line SU are equal to 90°

there is no proportional relationship between the two qualities

For two quantities to be proportional, it must follow the formula:

y = kx

where k = proiportionality constant

k = y/x

if y = 950, x = 1

inserting in the equation:

950= 1k

k = 950

The equation becomes: y = 950 × x

We check for other values. if k is the same, it is proportional

when y = 2852, x = 3

2852 = k × 3

k = 2852/3 = 950.67

when y = 5.1, x = 4845

4845 = k × 5.1

k = 4845/5.1 = 950

From the above, the value of k which is different is for the 2nd value.

Since they are not all the same, we say there is no proportional relationship between the two qualities

Step-by-step explanation:

You want to know which angle expression is not true.

We can figure the measures of all of the unknown angles, then check the given expressions.

Angles 'a' and 130° are corresponding angles, so congruent:

  a = 130°

Angles 'a' and 'e' are vertical angles, so congruent:

  e = a = 130°

Angle 'd' and 62° are vertical angles, so congruent:

  d = 62°

Angles 'b' and 'd' are corresponding angles, so congruent:

  b = d = 62°

Angles 'f' and 62° are corresponding angles, so congruent:

  f = 62°

Angles 'c' and 130° are a linear pair, so supplementary:

  c + 130° = 180°

  c = 50° . . . . . . subtract 130°

(a) ∠e +∠d = 180°   ⇒   130° +62° = 180° . . . . false

(b) ∠d +∠b = 124°   ⇒   62° +62° = 124° . . . . true

(c) ∠a +∠c = 180°   ⇒   130° +50° = 180° . . . . true
