Step-by-step explanation:

There are 6 possible outcomes when rolling a number cube, and each outcome is equally likely.

Probability is simply the likelihood of something occurring. When we are uncertain about the outcome of an event.

There are 6 possible outcomes when rolling a number cube, and each outcome is equally likely.

Since we are interested in the number of times the cube lands on a number greater than 4, we only need to consider the outcomes 5 and 6.

The probability of rolling a 5 or a 6 on one roll of the cube is 2/6, or 1/3. Therefore, we can expect Xavier to roll a number greater than 4 about 1/3 of the time.

To find out how many times he can expect it to happen in 90 rolls, we can multiply the probability by the number of trials:

Expected number of rolls with a number greater than 4 = (1/3) x 90 = 30

Therefore, Xavier can expect the cube to land on a number greater than 4 about 30 times out of 90 rolls.

No

Step-by-step explanation:

just follow the directions

Answer:

Conduction is the transfer of thermal energy through direct contact between particles of of a substance, without moving the particles to a new location. Conduction usually occurs in solids. Convection is the transfer of thermal energy through movement of particles from one location to another. Convection usually occurs in liquids. Radiation is the emission of energy as waves or particles or rays. Radiant energy is either reflected or absorbed by matter. Convection causes things like the rain cycle and radiation comes from things like the sun.

Answer:

slope = 3/4

Step-by-step explanation:

slope = (difference in y)/(difference in x)

slope = (-5 - 4)/(-2 - 10) = -9/(-12) = 3/4

Answer:

[tex]\sqrt{290}\approx 17.0\text{ units}[/tex]

B)

[tex]\sqrt{53}\approx7.3\text{ units}[/tex]

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Problem 1)

We have the two points (-4, 5) and (7, 18).

Let (-4, 5) be (x₁, y₁) and let (7, 18) be (x₂, y₂).

Substitute:

[tex]d=\sqrt{(7-(-4))^2+(18-5)^2}[/tex]

Evaluate:

[tex]\begin{aligned}d&=\sqrt{(11)^2+(13)^2}\\&=\sqrt{121+169}\\&=\sqrt{290}\approx17.0\end{aligned}[/tex]

Problem 2)

We have the two points (-2, -3) and (-4, 4).

Similarly, we will let (-2, -3) be (x₁, y₁) and (-4, 4) be (x₂, y₂).

Substitute:

[tex]d=\sqrt{(-4-(-2))^2+(4-(-3))^2[/tex]

Evaluate:

[tex]\begin{aligned}d&=\sqrt{(-2)^2+(7)^2}\\&=\sqrt{4+49}\\&=\sqrt{53}\approx7.3\end{aligned}[/tex]

Step-by-step explanation:

78 - 2x = 89 - 3x

Add 3x to both sides

78 - 2x + 3x = 89

78 + x = 89

Subtract 78 from  both sides

x = 89 - 78

x = 11

Answer:

a=7

Step by step Explanation:

Step 1: Simplify both sides of the equation.

1.3(a+2)+5.6=17.3

(1.3)(a)+(1.3)(2)+5.6=17.3(Distribute)

1.3a+2.6+5.6=17.3

(1.3a)+(2.6+5.6)=17.3(Combine Like Terms)

1.3a+8.2=17.3

1.3a+8.2=17.3

Step 2: Subtract 8.2 from both sides.

1.3a+8.2−8.2=17.3−8.2

1.3a=9.1

Step 3: Divide both sides by 1.3.

1.3a      9.1

1.3     =   1.3

a = 7

Step-by-step explanation:

Multiply the top and bottom by 2 to get the fraction in terms of 100. This will make the problem a lot easier.

29/50 = 58/100 = 0.58

Simplest form of the number 29/50 as a decimal number⇒ 0.58

A fraction is a part of whole number, and a way to split up a number into equal parts. and number which is expressed as a quotient is called fraction. It can be written as the form of p : q, that is equivalent to p / q.

We are Given that 29/50 as fraction

Now, We can simplify the fraction as Multiply the top and bottom by 2 to get the fraction in terms of 100.

29/50 = 58/100

Thus, Simplest form of the number

Answer: The velocity of the ball is 108.8 ft/s downwards.

Step-by-step explanation:

When the ball is dropped, the only force acting on the ball will be the gravitational force. Then the acceleration of the ball will be the gravitational acceleration, that is something like:

g = 32 ft/s^2

To get the velocity equation we need to integrate over time, to get:

v(t) = (32ft/s^2)*t + v0

where v0 is the initial velocity of the ball. (t = 0s is when the ball is dropped)

Because it is dropped, the initial velocity is equal to zero, then we get:

v(t) = (32ft/s^2)*t

Which is the same equation that we can see in the hint.

Now we want to find the velocity 3.4 seconds after the ball is dropped, then we just replace t by 3.4s, then we get:

v(3.4s) = (32ft/s^2)*3.4s = 108.8 ft/s

The velocity of the ball is 108.8 ft/s downwards.

Answer:

y = 6/5x -5

Step-by-step explanation:

Points are (5,1) (0,-5)

-5 - 1/ 0-5 = 6/5 slope

y-y1= m(x-x1)

y- 1 = 6/5(x-5)

y -1 = 6/5X - 6

y = 6/5X -5
