We minus 3 on both sides, we get :
2x = 3x - 2

We have the equation : 3x - x = 2x, or 2x = 3x - x, and this holds true.
Since x corresponds to 2 in the first equation, x = 2 is a solution

Using the binomial distribution, there is a 0.6328 = 63.28% probability that she wins at most 1 prize.

For each box, there are only two possible outcomes, either it has a prize, or it does not. The probability of a box having a prize is independent of any other box, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

In this problem:

She buys 5 boxes, hence

1 in 4 boxes has a prize, hence

The probability is:

P ( X ≤ 1 ) =P ( X = 0 ) + P ( X = 1 )

Then ,

P ( X ≤ 1 ) = P ( X = 0 ) + P ( X = 1 )

= 0.2373 + 0.3955

= 0.6328

Thus 0.6328 = 63.28% probability that she wins at most 1 prize

(4,-2) does not lie on the line

Here, we want to select the point that is not a solution to the graphed line

What we have to do is just to susbtitute the value of x and y. If by aritjmetic operation, the result is 16, then the point lies on the line

We proceed as follows;

a) (4,-2)

-2(4) -4(-2)

-8+8 = 0

This lies on the line

b) (1, -4.5)

-2(1)-4(-4.5) = -2 + 18 = 16

This is not on the line

c) (-2,-3)

-2(-2)-4(-3) = 4 + 12 = 16

d) -2(-5)-4(-1.5)

= 10 + 6 = 16

As we can see, only the first point does not lie on the line

Step-by-step explanation: Out of the 50 times the coin was flipped, it landed on tails 35 times. This means it landed on heads 15 times (50-35=15). The ratio of heads to the total number of flips would be 15:50.

Answer:
y= [tex]-\frac{4}{3}x-\frac{7}{3}[/tex], so [tex]-\frac{4}{3}[/tex] is your slope!

Step-by-step explanation:

It's best to get this equation in slope-intercept form, meaning to solve for y.

My work is shown below, as to how I solve for y.

4x + 3y = -7

3y = -7 - 4x

Afterward, divide the other side by 3.

y = (-4/3)x (-7/3)

That's how you get the answer. Hope this helped.

As, y = mx + b, and the m stands for the slope, -4/3 is your slope.

If Stella walks down a flight of stairs to the basement. Then she walks back up the stairs and another flight of stairs to the second floor of her house. How far is Stella above the ground is: 12 ft.

Given:

Flight stair = 12 feet

Hence,

Let walking from down a flight of stairs to the basement = -12 f

Let  walking back up the stairs = 12Ft

Now let determine Stella height above the ground.

Height = -12 feet + 12 feet + 12 feet

Height = 12 feet

Therefore we can conclude that Stella is 12 feet above the ground.

When the plane reaches an altitude of 2,000 ft temperature will be 59.3F

The height of a thing above the surface of a planet or natural satellite, like the sea or land is known as altitude.A distance measurement between a reference datum and a point or object, typically in the vertical or "up" direction, is known as altitude, height, or depth.

Although the term "altitude" is frequently used to refer to a location's height above sea level, the term "elevation" is frequently preferred in the context of geography. The term "depth" often refers to vertical distance measurements taken in the "down" direction.

For every 1000 ft there is a drop of 1.2 Fahrenheit

∴ for 2000ft drop in temperature of 2×1.2=2.4F

Also the temperature on the ground is 61.7F

The temperature when the plane reaches 2,000 ft will be

61.7-2.4 = 59.3F

Answer

The initial amount on Jon's giftcard is $48.

Explanation

Let the initial amount on Jon's gift card be x dollars.

Jon pays $17 for a shirt using the gift card and the remaining balance was $31.

That is, the equation representing this is

x - 17 = 31

To solve this, we add 17 to both sides

x - 17 + 17 = 31 + 17

x = 48 dollars

The initial amount on Jon's giftcard is $48.

Hope this Helps!!!

Good evening,

Answer: x-17=31 is the equation you're looking for meanwhile its result is x=48

Explanations: Jon spent $18 after having $31 on the card so they're spending money off the card, therefore the equation you're loooking for is x-17=31. In order to solve it add 17 to the other side of the equation such as:

Hours satellite will take  to reach a star that is three light years away is 1.039 * [tex]10^{9}[/tex] hours.

Given :

satellite can move at 17,000 miles per hour.

let t be the number of hours

Convert the disance to miles

3 light years = 3 * 9.5 * [tex]10^{12}[/tex] kilometers

= 3 * 9.5 * [tex]10^{12}[/tex] * 0.62 miles

= 1.767 *  [tex]10^{13}[/tex] miles

divide by the speed to get the time in hours

t = 1.767 *  [tex]10^{13}[/tex] miles /17000 miles /hour

t = 1.039 * [tex]10^{9}[/tex] hours

Hence hours satellite will take  to reach a star that is three light years away is 1.039 * [tex]10^{9}[/tex] hours.

The possible coordinates of the point​ A is (-3, -5) and  (-3, 7)

The given parameters are:

This means that

A = (-3, y)

The distance between any two points is calculated as

D = √[(x₁ - x₂)² + (y₁ - y₂)²]

Substitute the known values in the above equation

So, we have

10 = √[(-3 - 5)² + (y - 1)²]

Evaluate the difference

10 = √[(-8)² + (y - 1)²]

Take the square of both sides

100 = (-8)² + (y - 1)²

So, we have

100 = 64 + (y - 1)²

Evaluate the like terms

(y - 1)² = 36

Take the square roots

y - 1 = ±6

This gives

y = 1 ± 6

So, we have

y = -5 and 7
