The tile showen are placed in a bag you randomly select one of the tiles return it to the bag and randomly selecting Lo tile what is the probability that the first number divided by the second number is greater than zero

Answers

Answer 1

Answer:

15

Step-by-step explanation:

Answer 2

The probability that the first number divided by the second number is greater than zero is 1/3

What is probability?

Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Tiles are numbered -2,-1,1,2

So, possibility first number divided by the second number is greater than zero

-2/-1=2

-2/1=-2

-2/2=-1

-1/-2= 0.5

-1/1=-1

-1/2=-0.5

1/-2=-0.5

1/-1=-1

1/2=0.5

2/-2=-1

2/-1=-2

2/2=1

Probability the first number divided by the second number is greater than zero = 4/12=1/3.

5x -6y=-32



3x+6y=48


solve using elimination, i have a bunch of these i need to get done

Answers

So this question is already perfectly set up. Since the 6 and -6 cancel you’ll be left with 5x + 3x which is 8x and -32 + 48 which is 16. 8x=16. Isolate x to get that x=2. Plug 2 back into one of the equations. 5(2) -6y = -32. Solve for y now. -10-32 equals -42. Divide -42 by -6 to get 7. So the final coordinate where the two equations will intersect is (2,7)

A missile is fired such that its height above the ground is given by h=-9.8t^2+38.2t+6.5, where t represents the number of seconds since the rocket was fired. Using the quadratic formula, determine, to the nearest tenth of a second, when the rocket will hit the ground.


Please I need help with this question

Answers

Answer:

4.1 sec

Step-by-step explanation:

-9.8t^2 +38.2t + 6.5 = 0

t = [tex]\frac{-38.2 +-\sqrt{38.2^2{ - 4(-9.8)(6.5)} } }{2(9.8}[/tex]

 =  [tex]\frac{-38.2 +- \sqrt{1459.24 + 254.8} }{-19.6}[/tex]

 = [tex]\frac{-38.2 +- \sqrt{1714.04} }{-19.6}[/tex]

 = [tex]\frac{-38.2 +- 41.4}{-19.6}[/tex]

 = [tex]\frac{-79.6}{-19.6}[/tex]

 = 4.1

The rocket will hit the ground at 0.2 seconds

Function

The function is given as:

[tex]h=-9.8t^2+38.2t+6.5[/tex]

When the missile hits the ground, the value of height is 0

This means that:

[tex]h = 0[/tex]

So, we have:

[tex]-9.8t^2+38.2t+6.5 = 0[/tex]

Graph

Next, we plot the graph of [tex]-9.8t^2+38.2t+6.5 = 0[/tex]

See attachment for the graph of [tex]-9.8t^2+38.2t+6.5 = 0[/tex]

From the attached graph, we have:

[tex]t = (0.163, -4.061)[/tex]

Approximate

[tex]t = (0.2, -4.1)[/tex]

Time cannot be negative.

So, we have:

[tex]t = 0.2[/tex]

Hence, the rocket will hit the ground at 0.2 seconds

Step-by-step explanation:

Two triangles are similar if the corresponding angels are congruent to each other and if the sides of the triangle are in proportion to each other

to determine if the triangles are similar, determine if the sides are in proportion to each other

CE = 10

BC = 6

10 / 6 = 1.67

DC = 15

AC = 9

15/9 = 1.67

The sides of the triangle are in proportion to each other, thus they are similar

Jalen is trying to set a pole that is 10 ft long into the ground so that it is perpendicular with the horizontal surface. Jalen locates a point 6 feet from the base of the pole, at C, and labels it A then he measures the distance from point a to b what distance to the nearest tenth of a foot does haley need for the pole to be perpendicular

Answers

Answer:

The distance from point A to B that Haley needs for the pole to be perpendicular is:

11.66 feet.

Step-by-step explanation:

To solve this exercise, imagine that it is a triangle, where the height is the pole, which is 10 feet, and the base of the triangle is the distance between the base of the pole and the point located by Jalen and called C, which it would have a measurement of 6 feet, finally, the measurement between A (the point located six feet) and B (the highest part of the pole) would correspond to the hypotenuse of a triangle,

Therefore, having these two measures, you could use the Pythagorean theorem to find the hypotenuse of a triangle with those measures and solve it, remember that the Pythagorean theorem is:

Hypotenuse^2 = opposite leg^2 + adjacent leg^2

We replace the values given in the exercise:

Hypotenuse^2 = (10 ft)^2 + (6 ft)^2Hypotenuse^2 = 100 ft^2 + 36 ft^2[tex]\sqrt{hypotenuse^{2} }[/tex] = [tex]\sqrt{100 ft^{2} +36ft^{2} }[/tex]Hypotenuse = [tex]\sqrt{136ft^{2} }[/tex]Hypotenuse = 11.66 ft approximately.

In this form, Jalen can be sure the pole is perpendicular to the ground when the distance from point A to B is 11.66 ft approximately.

what is the average rate of change of the population between 1930 and 1950? show your reasoning?

Answers

Answer:

The average rate of change is: 0.25

Step-by-step explanation:

Given

See attachment for graph

Required

The average rate of change between 1930 and 1950

Average rate of change (m) is calculated as:

[tex]m = \frac{f(b) - f(a)}{b - a}[/tex]

In this case,

[tex][a,b] = [1930,1950][/tex]

So, we have:

[tex]m = \frac{f(1950) - f(1930)}{1950 - 1930}[/tex]

[tex]m = \frac{f(1950) - f(1930)}{20}[/tex]

From the attached graph;

[tex]f(1950) = 45[/tex]

[tex]f(1930) = 40[/tex]

So, we have:

[tex]m = \frac{45- 40}{20}[/tex]

[tex]m = \frac{5}{20}[/tex]

[tex]m = 0.25[/tex]

Answers

Answer:

Y=5(x) Yes it is porportional.

Step-by-step explanation:

So lets look at the graph.

We first have 1x = 5y

Well, that makes it seem like for each x there are 5 y.

Lets see the other values:

2x = 10y

Divide both sides by 2 tog et x alone:

1x=5y

Again, for each x, there are 5y.

This is true for each one:

3x=15y

=

1x=5y

4x=20y

=

1x=5y

5x=25y

=

1x=5y

and finally:

6x=30y

=

1x=5y.

So yes, this is poroportional.

It can be shown as x=5y, since for a single x, there are 5 y's.
