What is the area of the right angle

Answers

Answer:

3.84 inches squared

Step-by-step explanation:

The area of a triangle is given by the formula:

Area = 1/2 * base * height

In this problem, our side lengths are:

Base = 2.4 inches

Height = 3.2 inches

So, our area can be found:

Area = 1/2 * 2.4 * 3.2 = 3.84 inches squared

Answers

Answer:

the coefficient of the squared expression in the parabolas equation: D. 3

Step-by-step explanation:

y = a (x-h)² + k parabola equation

y=-1 and x=3 vertex(h,k): (2,-4)

-1 = a * (3-2)² + (-4)

-1 = a - 4

a = -1 + 4 = 3

Answer: 7. x= 26, 9. x=11/y=3

Step-by-step explanation: Sorry for the terrible photo quality. Comment if you need more help : )

So, for the first examples given set all of the equations as equal to the other angle equation given.For problems like number 9, solve for the x's first (or whichever variable there's more of) you should solve for the x's like you did for the first problem, then set the equation to an A+B=180 format. The reason for this is two angles (in some cases more) on a straight line together will always equal 180 degrees. For 10. set the equations with x in them to that A+B=180 format. Then once you've found x plug it into 6x-7. When you have that answer set 8y+17 equal to the answer you got and solve for y.For 11 and 12. These ones can be a bit more complicated because of their visual appearance, however you just need to combine the earlier steps taken to solve the first couple of equations. Beginning with 12. If you ever see a Z pattern, know that the sides facing > and < ( the inside angles of the Z) are equal to each other. So you set the equations with x equal to each other, and once you get x plug it into the equation inside of the triangle. Since you've already been given 90, set the equation up like this: 43+90+(7y-20)=180. Because all the angles in a triangle are equal to 180 degrees. Then just solve for y. y=9Lastly for number 11. This one is by-far the hardest of all of them. You have to adjust how you look at the problem. You'll see that if you add (3x+49) it's actually congruent to (7x-23). once you figure out x you should then plug x into 3x giving you 54. The set up the equation like this 11y-1=54. That will give you y=5.

Answer:

x = 29

Step-by-step explanation:

Multiply both sides by 7:

[tex]4x-4=\frac{7x+21}{2}[/tex]

Multiply both sides by 2:

[tex]8x-8 = 7x+21[/tex]

Subtract 7x from both sides:

[tex]x-8=21[/tex]

Add 8 to both sides

What is the slope of a line parallel to the line whose equation is 9x+3y=-27
Fully simplify your answer.

Answers

Answer:

One example would be y = -3x

Step-by-step explanation:

We can more easily find a line parallel to the given equation if it is put in slope intercept form.

3y = -27 - 9x

y = -3x - 9

So the slope is -3. You can choose any line also with a slope of -3.

A survey found that 20% of the people in Fiji drive the car without seatbelt. If 3 people are randomly selected, find the probability that at least 2 drive without seat.

Answers

Answer:

0.104 = 10.4% probability that at least 2 drive without a seatbelt.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they drive without a seatbelt, or they do not. The probability of a person driving without a seatbelt is independent of any other person. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

20% of the people in Fiji drive the car without seatbelt.

This means that [tex]p = 0.2[/tex]

3 people are randomly selected

This means that [tex]n = 3[/tex]

Find the probability that at least 2 drive without a seatbelt?

This is:

[tex]P(X \geq 2) = P(X = 2) + P(X = 3)[/tex]

In which

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{3,2}.(0.2)^{2}.(0.8)^{1} = 0.096[/tex]

[tex]P(X = 3) = C_{3,3}.(0.2)^{3}.(0.8)^{0} = 0.008[/tex]

[tex]P(X \geq 2) = P(X = 2) + P(X = 3) = 0.096 + 0.008 = 0.104[/tex]

0.104 = 10.4% probability that at least 2 drive without a seatbelt.

The 4 - 4 cancels out

So, -9 - 4 is -13

Then we change the sign because we cannot leave x negative.
