<u><em>Answer</em></u> ...........> The percentage of student expected to major physics in university is 2%

<u><em>Explanation:</em></u>

We are given that 66 students are expected to major physics in university.

We are also given that the total number of students in the university is 3300 students.

Therefore,

estimated % of university students that will be majoring physics = \frac{66}{3300} * 100 = 2 %

Hope this helps :)

A spinner has 5 equal sections numbered 1 to 5. What is the probability of the spinner stopping on a number that is a multiple o
Umnica [9.8K]

Answer:

0.6

Step-by-step explanation:

Given that the spinner has 5 equal sections numbered 1 to 5.

  • Total Sample Space, n(S)=5

Multiples of 2 in 1 to 5 are: {2,4}

Number less than  than 3 are:{1,2}

Since we are required to find the probability of the spinner stopping on a number that is a multiple of 2 or is less than 3, we take the union of both sets.

{2,4} \cup {1,2} ={1,2,4}

Number of Outcomes=3

Therefore,

Probability of the spinner stopping on a number that is a multiple of 2 or is less than 3  =\dfrac{3}{5}=0.6

\blue{\textsf{\textbf{Question:-}}}

What is the equation of the line parallel to y=-5x-9 and contains the point (-3, -3)?

\blue{\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

First of all, parallel lines have the exact same slope.

So we know the slope of the line:- -5.

(enter -5, It's the number that belongs in the green box)

How about the y-intercept?

Well, since we're given the slope and a point that the line intersects, we can write the line's equation in point-slope form:-

y-y1=m(x-x1)

y-(-3)=-5(x-(-3)

y+3=-5(x+3)

y+3=-5x-15

y=-5x-18

<h3>Good luck.</h3>
