The probability that someone who does not study calculus studies physics is 0.5

Since there are 1000 students in the school and 600 study physics, 300 study Calculus, and 100 study both, we need to find the number of students that study only physics to find the probability that someone who does not study calculus studies physics.

Let x = number of students who study both = 100, y = number of students who studies only physics and z = number of students who studies only calculus.

Given that the number of students who study physics are 600, we have

x + y = 600  (1)

Also, given that the number of students who study calculus are 300, we have

x + z = 300  (2)

From (1)

y = 600 - x

y = 600 - 100

y = 500

So, the probability of students that study only physics = probability that someone who does not study calculus studies physics  is

P(physics) = number of students studying only physics/total number of students

= 500/1000

= 5/10

= 0.5

So, probability that someone who does not study calculus studies physics is 0.5

Step-by-step explanation:

Negative discriminant means that the fucntion has no real roots

so in the quadratic function b^2-4ac if this section is negative there are no real roots, so yes a would be the answer

Bonus: if u want to know.

However, in linear algebra which ofc i know ur not taking there would be something called imangiary roots, or complex roots.

Answer:

She will have 142 watermelons

Step-by-step explanation:

First let's put our ratio

10 : 71

Since our lemons are now 20 instead of 10 we will divide 20 by 10 to see how many time we multiplied it by.

[tex]20 \div 10[/tex]

which equals 2

To find our water melon we will multiply it by 2

[tex]71 \times 2[/tex]

which equals 142

She will have 142 watermelons

C. y = (x – 2)^2  = Rewrite in vertex form and use this form to find the vertex  ( h , k ) .   ( 2 , 0 )  =Already in vertex form.   y = ( x − 2 ) ^2

Step-by-step explanation:  I used math.way

A. y = (x – 2)^2 + 4  = Rewrite in vertex form and use this form to find the vertex  ( h , k ) .   ( 2 , 4 )  =Already in vertex form.   y = ( x − 2 ) ^2 + 4

B. y = x^2 – 4  = Rewrite in vertex form and use this form to find the vertex  ( h , k ) .   ( 0 , − 4 )  =Find the vertex form.   y = ( x + 0 ) ^2 − 4

C. y = (x – 2)^2  = Rewrite in vertex form and use this form to find the vertex  ( h , k ) .   ( 2 , 0 )  =Already in vertex form.   y = ( x − 2 ) ^2

D. y = (x – 4)^2 – 4  = Rewrite in vertex form and use this form to find the vertex  ( h , k ) .   ( 4 , − 4 )  =Already in vertex form.   y = ( x − 4 ) 2 − 4
