Answer:

The probability is 1/2 or 50%

Step-by-step explanation:

We have 3 numbers that are divisible by 2 (2, 4, 6)

We find the probability by dividing the favorable results (3) by the # of all results (6).

3/6=1/2=0.5=50%

Answer:

1/2

Step-by-step explanation:

Probability is essentially (# times a specific event occurs) / (# times the general event occurs).

Here, the specific event is rolling a number that is divisible by 2. The numbers divisible by 2 from 1 to 6 are 2, 4, and 6. Since there are 3 such numbers, the specific event can occur 3 times.

The general event is simply rolling any number. Because there are 6 numbers we can roll, the number of times the general event can occur is 6.

So, the probability is 3/6 = 1/2.

How many solutions are possible for a system of equations containing exactly one linear and one quadratic equation? (Select all

galina1969 [7]

Remember that a quadratic equation is a parabola. The equation is of the type y = Ax^2 + Bx + C

A linear equation is a straight line. The equation is of the type y = MX + N

The soluction of that system is Ax^2 + Bx + C = MX + N

=> Ax^2 + (B-M)x + (C-N) = 0

That is a quadratic equation.

A quadratic equation may have 0, 1 or 2 real solutions. Those are all the possibilitis.

So you must select 0, 1 and 2.

You can also get to that conclusion if you draw a parabola and figure out now many point of it you can intersect with a straight line.

You will realize that depending of the straight line position it can intersect the parabola in none point, or one point or two points.

Given: mTP= 70°,m∠EPT = 54° Find: Angles of △SPT

Zigmanuir [339]

Answer:

The Angles of △SPT are

$m\angle STP=35\°$

$m\angle SPT=126\°$

$m\angle PST=19\°$

Step-by-step explanation:

step 1

Find the measure of angle PET

we know that

The inscribed angle is half that of the arc it comprises.

$m\angle PET=\frac{1}{2}(arc\ PT)$

substitute the given values

$m\angle PET=\frac{1}{2}(70\°)$

$m\angle PET=35\°$

step 2

Find the measure of angle PTE

we know that

The sum of internal angles of a triangle must be equal to 180 degrees

In the triangle PET

$m\angle PET+m\angle EPT+m\angle PTE=180\°$

substitute the given values

$35\°+54\°+m\angle PTE=180\°$

$m\angle PTE=180\°-89\°=91\°$

step 3

Find the measure of angle STP

we know that

The inscribed angle is half that of the arc it comprises.

$m\angle STP=\frac{1}{2}(arc\ TP)$

substitute the given values

$m\angle STP=\frac{1}{2}(70\°)=35\°$

step 4

Find the measure of angle SPT

we know that

$m\angle SPT+m\angle EPT=180\°$ ----> by supplementary angles

$m\angle SPT+54\°=180\°$

$m\angle SPT=180\°-54\°=126\°$

step 5

Find the measure of angle PST

we know that

The sum of internal angles of a triangle must be equal to 180 degrees

In the triangle SPT

$m\angle STP+m\angle SPT+m\angle PST=180\°$

substitute the given values

$35\°+126\°+m\angle PST=180\°$

$m\angle PST=180\°-161\°=19\°$

What is the verbal of p4 +6q

mario62 [17]

I am not sure what p 4 means, so I can't help you there.
Here are some of the possibilities: 
(p^4)^2 + 6q = p^8 + 6q 
(p4)^2 + 6q = 16p^2 + 6q 

the product of 18 and q is: 18q 

the sum of a number x and 10 is: (x + 10) 
Since you did not specify what number, I let the number be an arbitrary value x.

I just helped someone w/ the same question lol

please give me the area and perimeter for this shape and if possible please show your work I appreciate it :)

mariarad [96]

Solution
Short Answer P = 40 in
There are what looks like two parallel lines that are 7 inches long and two lines that are 13 inches long.

Perimeter = 2 * (Base + Slanted vertical lines that are parallel).
Perimeter = 2 * (7 + 13)
Perimeter = 2*20
Perimeter = 40 in

Area
Just in case you want it, the area is 11 * 7. The reason is that the height is perpendicular to the 7 in length.
