Answer:

-10x^2-5x-16

Step-by-step explanation:

collect like terms

-4x² – 26 + 7x – 6x² + 10 -12x =

-10x^2-16-5x

reorder it in ax^2+bx+c order

-10x^2-5x-16

Find the probability that the dart lands in the shaded circular region. The radius of the dartboard is 4 in, and the radius of t

PilotLPTM [1.2K]

Answer: The required probability is 0.25.

Step-by-step explanation:

Since we have given that

Radius of the dartboard = 4 in

Area of the dartboard is given by

$\pi r^2=3.14\times (4)^2=3.14\times 16=50.24\ in^2$

Radius of the shaded region = 2 in

Area of shaded region is given by

$\pi r^2=3.14\times (2)^2=12.56\ in^2$

So, the probability that the dart lands in the shaded circular region is given by

$\dfrac{12.56}{50.24}=0.25$

Hence, the required probability is 0.25.

Which angle in the isosceles triangles is the biggest?

IgorC [24]

Answer:

Since the two base angles are congruent (same measure), they are each 70°. If we are given a base angle of say 45°, we know the base angles are congruent (same measure) and the interior angles of any triangle always add to 180°.

A die is rolled. What is the probability that the number is a factor of 6 or more than 2? Does this scenario represent mutually

goblinko [34]

Factors of 6 are : 1,2,3 and 6.

Let us find probability of getting the number that is a factor of 6.

$P(\text{ The number is a factor of 6})=\frac{4}{6} =\frac{2}{3}$

Now let us find probability of getting a number more than 2 (3,4,5,6).

$P(\text{ The number is a greater than 2})=\frac{4}{6} =\frac{2}{3}$

We can see that these two events are mutually inclusive events. We can find probability of mutually inclusive events by formula $P(\text{X or Y})=P(X)+P(Y)-P(\text{X and Y})$ .

$P(\text{ The number is a factor of 6 and greater than 2})=\frac{2}{6} =\frac{1}{3}$

Now we will find probability of getting the number is a factor of 6 or more than 2 using above formula.

$P(\text{ The number is a factor of 6 or greater than 2})=\frac{2}{3} +\frac{2}{3}-\frac{1}{3}$

$P(\text{ The number is a factor of 6 or greater than 2})= \frac{4}{3}-\frac{1}{3}=\frac{3}{3}=1$

Therefore, our probability will be 1 and this scenario represents mutually inclusive events.
