Answers

Answer 1
6a^5b-12a^3b^2
you want to multiply 3a^2 to each of the values inside the parentheses so it would be (3*2)(a^2*a^3)(b)-(3*4)(a^2*a)(b^2)
so (6)(a^2+3)(b)-(12)(a^2+1)(b^2)
and therefore the answer is 6a^5b-12a^3b^2

A = l · w

A = w (w + 0.6)

A = w² +.6w

Answer:

D

Step-by-step explanation:

w = width

l = length = w + 0.6

Area = ( l ) * ( w )

Area = ( w + 0.6 ) ( w )

Area = w^2 + 0.6w

In a certain board game, a 12-sided number cube showing numbers 1–12 is rolled. If 4 such number cubes are rolled, what is the probability that at least 1 number cube will show a number 8 or larger?

The probability that at least 1 number cube will show a number 8 or larger is 0.83.

What is a binomial distribution in probability?

In an experiment with two possible outcomes, the likelihood of exactly x successes on n repeated trials is known as the binomial probability (commonly called a binomial experiment). The binomial probability is

[tex]n^C_xp^xq^{n - x}.[/tex]

Given, In a certain board game, a 12-sided number cube showing numbers 1 to 12 is rolled.

So, Numbers that are 8 or larger is 8, 9, 10, 11, 12.

Now, The probability(p) of getting a number 8 or larger P(X ≥ 8) = 5/12.

hence q = 1 - p = 7/12.

Therefore, If 4 such cubes rolled the probability that at least 1 number cube will show a number 8 or larger is,

P(X≥ 8) = [tex]^4C_1(\frac{5}{12})(\frac{7}{12})^4+^4C_2(\frac{5}{12})^2(\frac{7}{12})^2+^4C_3(\frac{5}{12}^3)(\frac{7}{12})^1+^4C_4(\frac{5}{12})^4(\frac{7}{12})^0[/tex].

P(X≥ 8) = 4(0.41×0.115) + 6(0.173×0.34) + 4(0.072×0.58) + 1(0.030×1).

P(X≥ 8) = 0.283 + 0.35 + 0.167 + 0.030.

P(X≥ 8) = 0.83 or 83% chance.

Find the value of x and y from the figure, if A, B & C are points on the circle with centre O.

Answers

Answer:

x=55 y=125

Step-by-step explanation:

X= 110/2=55

if BC is 110, BAC=250

so Y=250/2=125

X=110 divided by 2=55 because x is half of the 110 . Since it’s quadratic inside the circle the opposite sides equals to 180 so 180-110=70 so Y =70

One bag contains 2 green marbles and 4 white marbles, and a second bag contains 3 green marbles and 1
white marble. If Trent randomly draws one marble from each bag, what is the probability that they are both
green?

Answers

Answer:

1/4

Step-by-step explanation:

the first bag has 2 green marbles out of 6 total marbles, so the probability of getting a green marble out of the first bag is 2/6, or 1/3.

the 2nd bag has 3 green marbles out of 4 total marbles, so the probability of getting a green marble is 3/4

then multiply those together

1/3 × 3/4 = 3/12, which is 1/4

So that's the probability
