The line segment AB has the endpoints (-21, -7) and (-6,3) Point C are partitions the line at a ratio of 4;1 What are the coordinates of point C?

Answers

Answer 1

The coordinates of point C are (-9, 1)

How to determine the coordinates of point C?

The points are given as:

A = (-21, -7)

B = (-6, 3)

m : n = 4 : 1

The coordinates of point C is calculated as:

[tex]C = \frac{1}{m+n} *(mx_2 + nx_1, my_2+ ny_1)[/tex]

So, we have:

[tex]C = \frac{1}{4+1} *(4 * -6 + 1 * -21, 4 * 3+ 1 * -7)[/tex]

This gives

[tex]C = \frac{1}{5} *(-45, 5)[/tex]

This gives

C = (-9, 1)

Hence, the coordinates of point C are (-9, 1)

Eight students share 12 mini oatmeal muffins equally and 6 students share 27 mini apple muffins equally.
Carmine is in both groups of students.
What is the total number of mini muffins Carmine gets?
Carmine gets
muffins.

Answers

Step-by-step explanation:

oatmeal 12/8 = 1.5 per student

apple 27/6 = 4.5 per student

carmine gets 1.5 + 4.5 = 6 muffins

Answer:

Step-by-step explanation:

(12 oatmeal)/(8 students) = (1.5 oatmeal)/student

Each student gets 1.5 oatmeal muffins.

(27 apple)/(6 students) = (4.5 apple)/student

Each student gets 4.5 apple muffins.

Carmine gets 1.5 oatmeal plus 4.5 apple = 6 muffins

B) What is the probability that at most three forms are required?
C) What is the probability that between two and four forms (inclusive) are required?
D) Could pX(x) = x^2/50 for x = 1, . . . , 5 be a probability distribution of X? Explain.

Answers

Answer:

Step-by-step explanation:

Given that:

P(Y) = ky

where;

y =1,2,...7

To find the value of c or k (constant)

[tex]\sum P(Y) = 1[/tex]

[tex]\sum \limits_{y \to 1}^7 k*y = 1[/tex]

= k(1+2+3+4+5+6+7) = 1

28k = 1

[tex]k = \dfrac{1}{28}[/tex]

b) The required probability is P ( X ≤ 3)

[tex]P(X \le 3) = \sum \limits^3_{y=1 } P(y)[/tex]

[tex]P(X \le 3) = \sum \limits^3_{y=1 } \dfrac{1}{28}(y)[/tex]

[tex]P(X \le 3) = \dfrac{1}{28} (1 +2+3)[/tex]

[tex]P(X \le 3) = \dfrac{6}{28}[/tex]

P ( X ≤ 3) = 0.2143

c) The required probability P(2 ≤ Y ≤ 4)

[tex]P(2 \le Y \le 4) = \sum \limits ^4_{y=2} P(Y)[/tex]

[tex]P(2 \le Y \le 4) = \sum \limits ^4_{y=2} \dfrac{1}{28}(Y)[/tex]

[tex]P(2 \le Y \le 4) = \dfrac{1}{28}(2+3+4)[/tex]

[tex]P(2 \le Y \le 4) = 0.3214[/tex]

d) The required probability:

[tex]P(X) = \dfrac{x^2}{50} ; \ \ \ \ where; \ x= 1,2,...5[/tex]

[tex]\sum \limits ^5_{y =1} P(Y)= \sum \limits ^5_{y =1} \dfrac{1}{50}(x)^2[/tex]

[tex]\sum \limits ^5_{y =1} P(Y)= \sum \limits ^5_{y =1} \dfrac{1}{50}(1+4+9+16+25)[/tex]

[tex]\sum \limits ^5_{y =1} P(Y)=1.1[/tex]

Answers

Step-by-step explanation:

A discrete variable can be defined as a definite variable that we can get it's possible values just by counting. With this in mind.

1. The number of countries ever visited is a discrete variable

2. Shoe size is definite, it is a discrete variable.

3. Number of pets living in a household is a discrete variable.

A continuous variable is one that we can get the value through measurements.

1. Pounds of chocolate consumed in the past is continuous

2. Height in inches is continuous

Answer and Step-by-step explanation:

31 degrees on the top would be equal to the angle in between x and 600ft, by the interior angles theorem.

That means we can solve for y using the trigonometric function of tangent.

Multiply by 600 to both sides, then use a calculator to solve.

600(tan(31)) = x

x = 360.5163714

x ≈ 360.5 is the answer.

The probability of a head is 0.27. The coin is thrown 200 times. Write an

estimate for the amount of tails

Answers

Answer:

The estimate for the amount of tails is 146.

Step-by-step explanation:

For each throw, there are only two possible outcomes. Either it is a head, or it is tails. Throws are independent. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

The probability of a head is 0.27.

This means that the probability of tails is [tex]p = 1 - 0.27 = 0.73[/tex]

The coin is thrown 200 times.

This means that [tex]n = 200[/tex]

Write an estimate for the amount of tails

This is the expected value, so:

[tex]E(X) = np = 200*0.73 = 146[/tex]

The estimate for the amount of tails is 146.
