PLEASE HELP with question 7! BRAINLIEST to correct answer!!!!

× whats the point of this

The likelihood of selecting a classmate at random who does not have an A is 6/19.

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

To find the probability of a student not having an A, we need to first find the total number of students who do not have an A.

The number of students who have an A is 13, so the number of students who do not have an A is:

19 - 13 = 6

Out of these 6 students, 4 are male and 2 are female.

So, the probability of choosing a student randomly who does not have an A is:

P(not A) = number of students without an A / total number of students

P(not A) = 6 / 19

Therefore, the probability of choosing a student randomly from the class who does not have an A is 6/19.

Answer:

The length of the side DE is approximately 541.3 feet long.

Step-by-step explanation:

There is a trigonometry law called the law of sines, which states the sine of an angle divided by its opposite side is equivalent to the sine of all the other angles in that right triangle divided by its corresponding opposite side. You can use this law to help you solve for x. By applying the law of sines, you'll get that [tex]\frac{sin(90^{o})}{x} =\frac{sin(10^{o})}{94}[/tex] ⇒ [tex]\frac{x}{sin(90^{o})} =\frac{94}{sin(10^{o})}[/tex] ⇒ [tex]x = \frac{94*sin(90^{o})}{sin(10^o)}[/tex] ⇒ [tex]x=541.3ft.[/tex]

Step-by-step explanation:

Answer:

X =50                  Y is also 50 since they are vertical angles

Step-by-step explanation:

70+ 60 + X = 180  (the 3 angles form a straigh line = 180 )

130 +X =180

X = 180-130

X=50

Answer:

Finding the product of 9, 10 and 9 ; 810

Step-by-step explanation:

Given that :

Length = 10 feets

Width = 9 feets

Height = 9 feets

The volume of a rectangular prism is obtained by :

Length * width * height

The volume could be obtained by taking the product of 10, 9 and 9

Hence, the volume of the rectangular prism is :

(10 * 9 * 9) feet³ = 810 feet³

Number of 1 feet³ boxes = 810 feet³ / 1 feet³ = 810

Step-by-step explanation:

Note: We need to find the number of total box tops instated of total number of cans.

Given:

Trinity collected 36 box tops.

Peyton collected [tex]1\dfrac{1}{2}[/tex] times as many as Trinity.

To find:

The number of box tops they did collect all together.

Solution:

It is given that,

Number of box tops collected by Trinity = 36

Number of box tops collected by Peyton = [tex]1\dfrac{1}{2}\times 36[/tex]

                                                                    = [tex]\dfrac{3}{2}\times 36[/tex]

                                                                    = [tex]54[/tex]

Total = [tex]36+54[/tex]

        = [tex]90[/tex]

Therefore, the total number of box tops collect all together is 90.

Answer:

The missing measure of the arc is 125°.

Step-by-step explanation:

Since the circle is 360°, you would first subtract 360 by the degrees given: 360-115-35-85 and the sum is 125. Then, you would set 125 equal to -32x-3 to solve for x.

[tex]125=-32x-3[/tex]

[tex]+3[/tex]               [tex]+3[/tex]

-----------------------

[tex]\frac{128}{-32} =\frac{-32x}{-32}[/tex]

[tex]x=-4[/tex]

The missing measure of the arc is 125°.

Answer:

t = 2 seconds

Step-by-step explanation:

Given that,

h = -16[tex]t^{2}[/tex] + 64 t

where h and t have their usual meaning.

To determine the number of seconds required of the ball to hit the ground, differentiate the given equation with respect to t.

0 = -32 + 64

So that,

32t = 64

t = [tex]\frac{64}{32}[/tex]

t = 2

The ball will hit the ground in 2 seconds.

Answer:

x=3

Step-by-step explanation: too much math to put here

Answer:

x= 3 ; (x=1 is an extraneous solution)

Step-by-step explanation:

-2x+6 is under a square root, so its value must be > or equal to 0

If we solve the inequality

-2x+6 ≥ 0 we obtain

-x+3≥ 0

-x ≥ -3

x ≤ 3

now that we know the possible values of x we can proceed like this:

1) move 3 on the left side of equal and change its sign

x-3 = √-2x+6

2) square the two members of the equation

x^2 + 9 -6x = -2x+6

3) solve the equation

x^2 -4x +3  = 0

(x-3)(x-1) = 0

x = 3

x = 1

4) Check if the solution are ≤ 3 and if they make true the equation

Both solutions are ≤ 3

if x = 3

3 = √-6+6 + 3

3 = 3

true

x=1

1 = √-2+6 + 3

1 = 2+3

1 = 5 false

In conclusion we can say the 3 is a real solution, while 1 is an extraneous solution

Answer:

$20

Step-by-step explanation:

Kenny's gameplay: 1 month

Angie's gameplay: 3 months

1+3= 4

Kenny bought 1 software pack

Angie bought 2 software packs

Each software package= $30

So 30×3= 90

Total cost= $170

170-90= 80

80÷4= $20

Answer:

17

Step-by-step explanation:

Create a system of equations where t is the number of t shirts he sold, and s is the number of sweatshirts he sold

t + s = 28

12t + 20s = 424

Solve by elimination by multiplying the top equation by -20, then adding them together

-20t - 20s = -560

12t + 20s = 424

-8t = -136

Solve for t:

t = 17

So, Colton sold 17 t shirts
