the distribution of colors of candies in a bag is as follows. if two candies are randomly drawn from the bag with replacement, what is the probability that they are the same color?

Answer:

I tried as I can to solve it

Step-by-step explanation:

A

for a linear function the slope ratio has to be the same between every pair of data points.

between (1, 4) and (2, 8) we have

x changes by +1 (from 1 to 2).

y changes by +4 (from 4 to 8).

the slope is

+4/+1 = 4

between e.g. (2, 8) and (3, 16) we have

x changes by +1 (from 2 to 3).

y changes by +8 (from 8 to 16).

the slope here is +8/+1 = 8.

which is not the same as 4.

so, it is not a linear function.

it is an exponential function.

B.

the function is actually

f(x) = y = 2^(x+1)

an exponential function is of the form

y = a^x

in our case we have

4 = a¹ = 2²

8 = a² = a¹×2 = 2² × 2 = 2^(2+1)

16 = a³ = a²×2 = a¹×2×2 = 2²×2×2

we see

f(n) = a1×2^(n-1) = 2²×2^(n-1) = 2^(n+1)

C.

the average rate of change is

(the difference of the function results at the interval ends) / (the difference of the interval ends).

so, in our case

(f(4) - f(2))/(4 - 2) = (32 - 8)/2 = 24/2 = 12

the average rate of change between stations 2 and 4 is 12 (or 12/1).

Answer:

y = –5x/4 + 7

Step-by-step explanation:

x1 = 8 ,x2 = 4, y1 = –3 , y2 = 2

lets find the slope(m)

m = y2–y1/x2–x1

m = 2 – (–3)/ 4 – 8

m = 5/ –4

m= –5/4

to find the equation of a line using this as our guider y = mx + b

we will make use of one coordinate

(8,–3)

using the formula for one point

y – y1 = m(x – x1)

y – (–3) = –5/4(x – 8)

y + 3 = –5x/4 + 10

y = –5x/4 + 10 –3

y = –5x/4 + 7

Answer:

70.5%

Step-by-step explanation:

If a continuous random variable X is normally distributed with mean μ and variance σ², it is written as:

[tex]\large\boxed{X \sim\text{N}(\mu,\sigma^2)}[/tex]

Given:

Therefore, if the weights of the 12-month-old baby boys are normally distributed:

[tex]\boxed{X \sim\text{N} \left(22.5,2.2^2 \right)}[/tex]

where X is the weight of the baby boy.

To find the percentage to the nearest tenth of 12-month-old baby boys who weigh between 19.7 and 24.4 pounds find P(19.7 ≤ X ≤ 24.4).

Calculator input for "normal cumulative distribution function (cdf)":

[tex]\implies \text{P}(19.7 \leq X \leq 24.4)=0.704548741[/tex]

[tex]\implies \text{P}(19.7 \leq X \leq 24.4)=70.5\%[/tex]

Therefore, the percentage of 12-month-old baby boys who weigh between 19.7 and 24.4 pounds is 70.5% (nearest tenth).

Step-by-step explanation:

36 is the answer

By using the formula for area of rectangle, it can be calculated that Area of the median is 2400 sq. feet

What is area of rectangle?

The area of a rectangle is calculated by multiplying the length by the width. For example, if a rectangle has a length of 10 feet and a width of 6 feet, the area would be 10 x 6 = 60 square feet. The area of a rectangle is a two-dimensional measurement and is typically expressed in units squared, such as square feet or meters squared. Other shapes, such as a triangle or a circle, also have areas and are calculated differently.

If l is the length of the rectangle and b is the breadth of the rectangle, then area of rectangle is calculated by the formula

Area = [tex]l \times b[/tex]

Length of the median = 300 feet

Width of the median = 8 feet

Area of the median = 300 [tex]\times[/tex] 8 = 2400 sq. feet

Answer:

Yes, the lines are parallel. This is because the lines have the same slope. The slope of a line is a measure of how steep the line is, and it is calculated by taking the difference of the y-coordinates of two points on the line and dividing it by the difference of the x-coordinates of the same two points. In this case, the slope of line a is -1, and the slope of line b is also -1. Because the lines have the same slope, they are parallel to each other.

In  linear equation, He travels at a greater speed from his friend's house, at a rate of 0.6667 miles per minute, that is, 2 miles in 3 minutes.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.  

                             Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Using linear function concepts, it is found that:

Seth starts closer to the school in the bus.

He travels at a greater speed from his friend's house, at a rate of 0.6667 miles per minute, that is, 2 miles in 3 minutes.

From the graph of the bus, when he takes the bus, he is 13 miles from the school, as he starts at position 4 and ends at 17.

At his friend house, he is 13 miles from the school only after 3 minutes, which means that the bus will be closer.

The scenario with the greater speed is the one with the higher slope, that is, higher rate of change, which is the change in distance divided by the change in time.

In the bus, change of 13 miles in 24 minutes, thus

       mᵇ = 13/24 = 0.5417

   From the friend's house, change of 2 miles in 3 minutes, thus

   mf = 2/3 = 0.6667

Thus, he travels at a greater speed from his friend's house, at a rate of 0.6667 miles per minute, that is, 2 miles in 3 minutes.

The properties of the triangles created from the original triangle based on triangle congruency rules are as follows;

SSS: The triangle created using the lengths of the three sides of the original should have the same length and angles as the original

The triangle formed using SSS is a unique triangle and no other triangle has similar dimensions

SAS: The lengths of the sides and the measure of the angles should be the same

The triangle created using SAS is a unique triangle and there is not a way to have a third side that has a different length

ASA; The triangle formed using the ASA of the original triangle should have the same length as the same lengths and angles as the original triangle

The triangle formed using ASA is a unique triangle and there is not a way to create a triangle that has a different side length.

Two triangles are congruent if the lengths of the three sides of one triangle are congruent to the three sides of the other triangle or if they meet the other conditions of triangle congruency.

Length of first measured side of the triangle = 52 units

Angle made by the first measured side with the horizontal = 41°

Length of the second measured side of the triangle = 87 units

Angle the second measured side makes with the horizontal = 33°

Length of the third measured side of the triangle = 113 units

Angle the third side makes with the horizontal ≈ 6.5°

Let the vertices of the first side be A and B, we get;

∠A = 180° - (41° + 33°) = 106°

∠C = 33° - 6.5° = 26.5°

∠B = 41° + 6.5° = 47.5°

SSS: The SSS (Side-Side-Side) congruency postulate states that if the three sides of one triangle are congruent to the three sides of another triangle, then the two triangles are congruent.

Therefore, the lengths of the sides and the measures of the angles of the triangle created using the lengths of the three sides of the original triangle will be the same as the original triangle.

The SSS congruency postulate indicates that the triangle created using the same lengths of the three sides of the original triangle is a unique triangle and there are no other triangles having the same side lengths but different angles

SAS: The Side-Angle-Side, SAS, congruency postulate states that if the adjacent sides and an included angle of a triangle are congruent to two adjacent sides and an included angle of another triangle, then the two triangles are congruent.

Therefore, the triangle formed using two sides of the original triangle and the included angle between them will have the same length as the sides of the original triangle, and the triangle formed using the SAS of the original triangle is unique

The length of the third side of the triangle created using the SAS measurement is always the same as the length on the original triangle

ASA: The Angle-Side-Angle, ASA, congruency postulate states that if two angles and the included side of one triangle are congruent to two angles and an included side of another triangle, then the two triangles are congruent.

The triangle formed using the ASA is a unique triangles and therefore and there is no way to create a triangle that has a different side length
