Need to find the product of (3a+3)(4a+1)

Answers

I used the FOIL method First outer inner last
I multiplied the first variables together (3a*4a) and got 12a^2
So just do what common sense tells you to do
Multiply the first parts of the quantities, the outer parts of the quantities, the inner parts of the quantities and the last parts of the quantities to get
12a^2+3a+12a+ 3
Then group it together
$12a^(2) + 15a + 3$

during unusual cold weather the temperature in Miami Beach was 10 this was 12 degrees more than in tallahassee what is the temperature in tallahassee

Answers

Miami Beach = 10°

This was 12° more than in Tallahassee.

Miami, 10° = 12° + Tallahassee

10° = 12° + T

10° - 12° = T

-2° = T

Temperature in Tallahassee is -2°

-2 degrees in Tallahassee

The expected number of heads in 500 tosses of an unbiased coin is:

Answers

Using the binomial distribution, it is found that the expected number of heads in 500 tosses of an unbiased coin is 250.

For each coin, there are two possible outcomes, either it is heads, or it is tails. The probability of a coin being head/tails is independent of any other coin, hence the binomial distribution is used.

Binomial distribution:

Probability of x successes on n trials, with p probability.

The expected number of successes is:

$E(X) = np$

In this problem:

500 tosses, hence $n = 500$ .
Unbiased, that is, equally as likely to be heads or tails, hence $p = 0.5$ .

The expected number of heads is:

$E(X) = np = 500(0.5) = 250$

A similar problem is given at brainly.com/question/24261244

There is a 50%, or 1/2, chance of getting heads on each flip. Each of the 500 trials is independent. Because there is a 1/2 chance of getting heads, you would expect half of them to land on heads. 500/2 = 250. You would theoretically expect 250 heads if you tossed an unbiased coin 500 times.

AA, BBB, and CCC are collinear, and BBB is between AAA and CCC. The ratio of ABABA, B to BCBCB, C is 1:21:21, colon, 2. If AAA is at (7,-1)(7,−1)left parenthesis, 7, comma, minus, 1, right parenthesis and BBB is at (2,1)(2,1)left parenthesis, 2, comma, 1, right parenthesis, what are the coordinates of point CCC?

Answers

Answer:

The coordinates of point C are (-8,5).

Step-by-step explanation:

It is given that A, B and C collinear and B is between A and C.

The ratio of AB to BC is 1:2. It means Point divided the line segments AC in 1:2.

Section formula:

$((mx_2+nx_1)/(m+n),(my_2+ny_1)/(m+n))$

The given points are A(7,-1) and B(2,1).

Let the coordinates of C are (a,b).

Using section formula the coordinates of B are

$B=(((1)(a)+(2)(7))/(1+2),((1)(b)+(2)(-1))/(1+2))$

$B=((a+14)/(3),(b-2)/(3))$

We know that point B(2,1).

$(2,1)=((a+14)/(3),(b-2)/(3))$

On comparing both sides we get

$2=(a+14)/(3)$

$6=a+14$

$6-14=a$

$-8=a$

The value of a is -8.

$1=(b-2)/(3)$

$3=b-2$

$3+2=b$

$5=b$

The value of b is 5.

Therefore, the coordinates of point C are (-8,5).

The coordinates of the pointC such that pointsA and B are (7, -1) and (2, 1) and the ratioAB to BC is 1 : 2 is (-8, 5).

How to determine the location of a point within a line segment

According to the Euclidean geometry, a line is formed by two points on a plane and three points are collinear if all the three points go through a single line.

By definitions of vector and ratio we derive an expression to determine the coordinates of the point B:

$\overrightarrow{AB} = (1)/(1+2)\cdot \overrightarrow{AC}$

$\vec B - \vec A = (1)/(3)\cdot \vec C -(1)/(3)\cdot \vec A$

$(1)/(3)\cdot \vec C = \vec B - (2)/(3)\cdot \vec A$

$\vec C = 3 \cdot \vec B - 2\cdot \vec A$

If we know that A(x,y) = (7, -1) and B(x,y) = (2, 1), then the coordinates of point C is:

C(x, y) = 3 · (2, 1) - 2 · (7, -1)

C(x, y) = (6, 3) + (- 14, 2)

C(x,y) = (- 8, 5)

The coordinates of the pointC such that pointsA and B are (7, -1) and (2, 1) and the ratioAB to BC is 1 : 2 is (-8, 5).

Remark

The statement is poorly formatted and reports mistakes. Correct form is shown below:

A, B and C are collinear and B is between A and C. The ratio of AB to BC is 1 : 2. If A is A(x, y) = (7, -1) and B(x, y) = (2, 1), what are the coordinates of point C?
