There are 28 elements in the sample space and the probability of a green card is 9/28

The given parameters are:

Red = 7

Green = 9

Blue = 12

The elements in the sample space is:

Elements =7 + 9 + 12

Evaluate

Elements = 28

Hence, there are 28 elements in the sample space

This is calculated as

P =Green/Elements

So, we have:

P = 9/28

Hence, the probability of a green card is 9/28

Using linear pairs,

By the exterior angle theorem,

[tex]2y=45+5(13)\\\\2y=45+65\\\\2y=110\\\\y=\boxed{55}[/tex]

Answer:

1: [tex]y=-1x-3[/tex]

2: [tex]y=0.8x+4.2[/tex]

3: [tex]y=2x-3[/tex]

Step-by-step explanation:

Question 1: When lines are parallel, that means they're slope is the same and there y-intercept is different. So the first step is to calculate the slope of BC. If you look at BC you'll notice it goes down by 2 and goes forward by 2 so the slope is -2/2 or -1. This completes one part of the slope-intercept form which is y=mx+b where m is the slope and b is the y-intercept. The y-intercept will be calculated using the point A. since the equation passes through point A

-1 = (-2)(-1) + b

-1 = 2 + b

-3 = b

y=-1x-3

Question 2: Same concept here, if you look at AC, you'll see it "rises" by 4 and "runs" by 5, thus the slope is 4/5. Since it passes through B we'll use that to find the y-intercept

5 = (4/5)(1) + b

5 = 4/5 + b

b = 4.2

Question 3: It "rises" by 6 and "runs" by 3, thus the slope is 6/3 which is 2.

Plug in known values

3=(3)(2) + b

3 = 6 + b

-3 = b

The values of the functions from the graph and table are; (f ° g)(4) = 4 and x = 0 at  (g ° f)(x) = 1

1) We want to find the value of (f ° g)(4). This can also be expressed as;

f(g(4))

Now, from the given graph, g(4) = 2. Thus;

f(g(4)) = f(2)

From the table, f(2) = 4. Thus;

(f ° g)(4) = 4

2) We are given; (g ° f)(x) = 1

This is also expressed as;

g(f(x)) = 1

From the graph g(x) = 1 is at x = 1. Thus;

f(x) = 1 and from the tabe;

x = 0 at f(x) = 1

The solution to the fraction expression at x = 1¹/₁₀ is: 10.97

The fraction expression is given as:

3(5 - ¹/₆x) + ¹/₈(32 + 6x) + 7.3x - 5 * 0.05x

Breaking this down gives us:

1. The equation of the parallel line is y = -x - 1.

2. The equation of the perpendicular line is y = 3/2x - 4.

Lines that are parallel have the same slope while slope values for perpendicular lines are negative reciprocals.

1. The slope (m) of y = -x + 1 is -1. Substitute m = -1 and (x, y) = (4, -5) into y = mx + b:

-5 = -1(4) + b

-5 = -4 + b

-5 + 4 = b

b = -1

Substitute b = -1 and m = -1 into y = mx + b

y = -x - 1

2. The slope (m) of y = -2/3x + 5 is -2/3.

Negative reciprocal of -2/3 is 3/2.

Substitute m = 3/2 and (x, y) = (2, -1) into y = mx + b:

-1 = 3/2(2) + b

-1 = 3 + b

-1 - 3 = b

b = -4

Substitute b = -4 and m = 3/2 into y = mx + b

y = 3/2x - 4

Hello,

look at the picture

From the first two inference, it takes her phone 1 minute to charge 2% i.e 1 minute of charge = 2% of battery.

Therefore; charging from scratch,

1 min = 2%

x mins = 50%.

using cross multiplication,

x mins = (50% × 1 min) ÷ 2%.

x = 25 mins.

For 90%, applying the same formula,

y min = (90% × 1 min) ÷ 2%

y = 45 mins.

So from zero percent, it will take Dana's phone 25 minutes to charge to 50% and 45 minutes to charge to 90%.

For the given systems A and B:

1) Replace the first equation of A by the sum between the two equations of A.

2) Yes, the systems are equivalent.

Here we have the two systems of equations:

A:

6x - 5y = 1

-2x + 2y = -1

B:

4x - 3y = 0

-2x + 2y = -1

The second equation is the same in both systems, so we only look at the first equations.

In A we have:

6x - 5y = 1

If we add the second equation of A, then we get:

(6x - 5y) + (-2x + 2y) = 1 + (-1)

4x - 3y = 0

This is the first equation of B.

Then we need to replace the first equation by the sum between the first and second equations.

2) Are the systems equivalent?

Yes, because we did not "modify" system A, we just rewrite it and we got system B, then both systems have the same solutions.

Step-by-step explanation:

sin theta=opposite/hyp

sin theta=500/680

theta in degrees=47.33

Answer:

The angle is 47.33°

Step-by-step explanation:

We have the hypotenuse as 680 ft and the opposite side as 500 ft, so we can use sin as a way to find the angle:

sin θ = opposite side / hypotenuse

sin θ = 500 ft / 680 ft

sin θ = 0.7353

θ = sin^-1 (0.7353) [this is called inverse of sine]

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

You require 450 mL of a 65% alcohol solution.

On hand, you have a 10% alcohol mixture.

Then the amount of the 10% alcohol mixture and pure alcohol that you need to obtain the desired solution will be

Let x be the amount of the 10% of alcohol is needed.

  d. Reflect across the y-axis and translate 9 units to down

Step-by-step explanation:

Reflection of the graph of a function across the y-axis is accomplished by replacing x with -x in the function definition.

Translation of the graph of a function by k units upward is accomplished by adding k to the function value.

Here, we observe that f(x) is g(x) with x replaced by -x. That means the graph of f(x) will be the graph of g(x) reflected across the y-axis.

The function f(x) is the function g(x) with -9 added to it. That translates the graph downward by 9 units.

These transformations, reflection across the y-axis and translation 9 units downward, can be seen in the attached graphs. Corresponding points are marked.

The average speed for the entire journey will be 53.333 miles per hour.

The average speed is the ratio of the total distance traveled to the total time taken by the body. Its unit is m/sec.

The distance from the Springfield, MA, to Boston is, L

v₁ is the velocity during traveling from Boston to Springfield, MA

v₂ is the  velocity during traveling from Springfield, MA to Boston

t₁ is the time needed to travel from Boston to Springfield, MA

t₂ is the time needed to travel from Springfield, MA to Boston

t is the total time period of the journey

v is the average speed

From the formula of distance;

Distance = speed × time

The speed of train for the going from Springfield, MA, to Boston is 40 mph. The time period is calculated as;

L = v₁ × t₁

t₁ = L/v₁

t₁ = L/40

The speed of train for the going from Boston to Springfield, MA, is 80 mph. The time period is calculated as;

L = v₂ × t₂

t₂ = L/v₂

t₂ = L/80

The total time is taken;

t = t₁ + t₂

t =  (L/40)+( L/80)

t=3L/80

The ratio of total distance traveled to the total time spent by the body is known as average speed, calculated as;

Average speed = Total distance / Total time

v = 2L / (3L/80)

v= (2L × 80)/3L

v = 160 / 3

v = 53.333 miles per hour.

Hence the average speed for the entire journey will be 53.333 miles per hour.
