Answer:

2/3

Step-by-step explanation:

There are 4 red balls and 8 yellow balls.

Therefore, there are total 12 balls in the bag.

n(S) = 12

Let A be the event when the ball drawn is not a red ball.

The balls which are not red will be yellow balls and there are 8 yellow balls so,

n(A) = 8

Probability that the ball drawn randomly from the bag is not a red ball,

p(A) = n(A) / n(S)

= 8/12

= 2/3

Therefore, the probability of the ball drawn randomly is not a red ball is 2/3.

k=

−2.75x2+3xy−5.5x−y/x

Step-by-step explanation:

Hi! so i see you need help with this problem let me help you and guide you through the steps :]

Let's solve for k.

k= y/x

(3x−1)−2.75(x+2)

Step 1: Multiply both sides by x.

kx=−2.75x2+3xy−5.5x−y

Step 2: Divide both sides by x.

kx/x

=

−2.75x2+3xy−5.5x−y/x

k=

−2.75x2+3xy−5.5x−y/x

Answer:

k=

−2.75x2+3xy−5.5x−y/x

Answer:

6

Step-by-step explanation:

The computation of the least possible whole number is shown below:

Here we need the factors of 150 i.e.

= 3 × 5 × 2 × 5

Here we can add  to one box and the 5 to the other box

And, now if we can add 3 to one box and in the other we can add 2 so they cant be equal to each other

Now lets try 5 × 6 and 5

So, here The perfect square is 900

= 30 × 30

= 900

Hence, the number would be 6

Answer:

y = 2

Step-by-step explanation:

4x - 3y = -18, then 4x = 3y - 18,                  x = (3y - 18)/4

6x + 7y = -4

substitute for x:

6((3y - 18)/4) + 7y = -4

(18y - 108)/4 + 7y = -4

4.5y - 27 + 7y = -4

combine like terms:

11.5y = 23

y = 2

check:

x = (3(2) - 18)/4 = -12/4 = -3

6(-3) + 7(2) = -4

-18 - 14 - -4

-4 = -4

so y = 2 is correct

Some parts of California are particularly earthquake-prone. Suppose that in one metropolitan area, 25% of all homeowners.....................

Answer:

[tex]P(X = x) = ^4C_x * 0.25^x * 0.75^{4-x}[/tex]

[tex]Mean = 1[/tex]

[tex]Pr = 0.2617[/tex]

Step-by-step explanation:

Given

[tex]n = 4[/tex]

[tex]p = 25\%[/tex]

Solving (a): The probability distribution of x

We have:

[tex]n = 4[/tex]

[tex]p = 25\%[/tex] [tex]= 0.25[/tex]

The probability of not having earthquake insurance (q) is:

[tex]q = 1 - p[/tex]

[tex]q = 1 - 0.25[/tex] [tex]= 0.75[/tex]

If x has insurance, then n - x do not.

The distribution follows a binomial pattern. So, the probability distribution is:

[tex]P(X = x) = ^nC_x * 0.25^x * 0.75^{n-x}[/tex]

Substitute 4 for n

[tex]P(X = x) = ^4C_x * 0.25^x * 0.75^{4-x}[/tex]

Solving (b): The most likely value of x i.e. The mean

We have:

[tex]n = 4[/tex] and

[tex]p = 25\%[/tex] [tex]= 0.25[/tex]

[tex]Mean = np[/tex]

[tex]Mean = 4 * 0.25[/tex]

[tex]Mean = 1[/tex]

Solving (c): At least 2 of 4 selected have earthquake insurance.

This is calculated as

[tex]Pr = P(x = 2) + P(x = 3) + P(x = 4)[/tex]

[tex]P(X = x) = ^4C_x * 0.25^x * 0.75^{4-x}[/tex]

[tex]P(X=2) = ^4C_2 * 0.25^2 * 0.75^{4-2}[/tex]

[tex]P(X=2) = 6 * 0.25^2 * 0.75^2 = 0.2109375[/tex]

[tex]P(X=3) = ^4C_3 * 0.25^3 * 0.75^{4-3}[/tex]

[tex]P(X=3) = 4 * 0.25^3 * 0.75 = 0.046875[/tex]

[tex]P(X=4) = ^4C_4 * 0.25^4 * 0.75^{4-4}[/tex]

[tex]P(X=4) = 1 * 0.25^4 * 1= 0.00390625[/tex]

So:

[tex]Pr = P(x = 2) + P(x = 3) + P(x = 4)[/tex]

[tex]Pr = 0.2109375 + 0.046875 + 0.00390625[/tex]

[tex]Pr = 0.26171875[/tex]

[tex]Pr = 0.2617[/tex] --- approximated

Answer:

[tex]f(x) = (x + 19)(x^2 + 1)[/tex]

Step-by-step explanation:

Complex numbers:

The following relation is important for complex numbers:

[tex]i^2 = -1[/tex]

Zeros of a function:

Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.

Has zeros −19 and −i

If -i is a zero, its conjugate i is also a zero. So

[tex]f(x) = a(x - (-19))(x - (-i))(x - i) = a(x+19)(x+i)(x-i) = a(x+19)(x^2 - i^2) = a(x + 19)(x^2 + 1)[/tex]

Output of 40 when x=1

This means that when [tex]x = 1, f(x) = 40[/tex]. We use this to find the leading coefficient a. So

[tex]f(x) = a(x + 19)(x^2 + 1)[/tex]

[tex]40 = a(20)(2)[/tex]

[tex]40a = 40[/tex]

[tex]a = 1[/tex]

The polynomial is:

[tex]f(x) = (x + 19)(x^2 + 1)[/tex]

Answer: 192.. just took the test :)

Step-by-step explanation:

The number of  boxes contains more than 340 nails will be 190. Option B is correct.

The number of standard deviations by which the value of a raw score is above or below the mean value of what is being observed or measured is known as the Z score.

Z score for the 340 nails is found as;

[tex]\rm Z-score= \frac{340-325}{15} \\\\ Z-score=1[/tex]

If the probability of the z score is grater than 1 is;

P(Z≥1)=1-P(Z≤1)

P(Z≥1)=1-0.8413

P(Z≥1)=0.1587

For the 1200 boxes with more than the 340 nails is 192.

Hence,option B is correct.
