Answer:

There is 30% probability for the students who score 60 marks in math.

Step-by-step explanation:

The probability of the students who score 60 marks in math is 30%. There is 70% chance that a student will score less than 60 marks in math. The students who score 60 plus in math will score lesser in English.

Given: AD diameter of circle P.<br> m AB + m BC = measure of<br> A)minor arc AC<br> B) major arc AC

Makovka662 [10]

In the given circle, m AB is represented by angle 1 and m BC is represented by angle 2 .

And

$m \ AB + m \ BC = \angle 1 + \angle 2 = m \AC$

And it represents the minor arc AC .

So the correct option is A.

Can you help with did pretty please I'm stuck help just a, c ,d thanks luv.

Answer:

a) The slope of the function is 3.

c) The equation is represented by $n(t) = 3\cdot t + 35$ .

d) The y-intercept of the function is 35.

Step-by-step explanation:

a) According to the statement, we must assume that number of pieces of mail that must be hand-sorted (dependent variable) is represented by a linear function in terms of time (independent variable). That is:

$n(t) = m\cdot t + n_{o}$ (1)

Where:

$m$ - Slope, measured in number of pieces per minute.

$t$ - Time, measured in minutes.

$n_{o}$ - Initial number of pieces of mail that must be hand-sorted (y-intercept), measured in pieces.

$n$ - Current number of pieces of mail that must be hand-sorted, measured in pieces.

From Geometry, we know that a line can be formed by know two distinct points. If we know that $n(15\,min) = 80\,p$ and $n(45\,min) = 170\,p$ , then the following system of linear equations is formed:

$15\cdot m + n_{o} = 80$ (2)

$45\cdot m + n_{o} = 170$ (3)

The solution of the system of equations is:

$m = 3$ and $n_{o} = 35$

The slope of the function is 3.

c) By (1) and using results from a) we conclude that the equation function is:

$n(t) = 3\cdot t + 35$ (4)

d) The y-intercept of the function is 35.

The number of ways in which you can win first prize and your mom went the second prize will be 8. Then the correct option is D.

<h3>What are permutation and combination?</h3>

A permutation is an act of putting things or elements in the right sequence. Combinations are a method of picking things or pieces from a collection of objects or sets when the sequence of the objects is irrelevant.

You and your mom enter the drawing with three different prices the prizes are awarded at random is a total of 8 people entered the drawing.

Then the number of the ways in which you can win first prize and your mom went the second prize will be

Let x be the number of different ways.

Then we have

$\rm x = \ ^8C_1\\\\x = 8$
