I NEED TO HAND IN NOW!!!

Mathematics
1 answer:
umka21 [38]3 years ago
5 0

Step-by-step explanation:

a)

total no. of pupils is not more than 24

therefore first equation is

(x+y) ≤ 24. ....(1)

No. of girls exceeding the no. of boys by atleast 4

(y-x) ≥ 4. .....(2)

b) Now Liza chooses 8 boys

Maximum no. of girls = ?

Using first inequality

y+8= 24 ( maximum value of less than or equal to function is equal to itself)

Therefore,

y= 24-8

=16

Minimum no. of girls = ?

Using second inequality

y-8 =4 (minimum value of greater than or equal to function is equal to itself)

Therefore,

y= 4+8

y=12

Answer:

a) 2linear inequalities

(x+y) ≤ 24

(y-x) ≥ 4

b) Max no. of girls = 16

Min no. of girls = 12

Hope it helps...

Answer:

The probability that a point randomly chose in the rectangle is in the triangle is \frac{1}{8}, so the answer would be A

Step-by-step explanation:

To find the probability of a random point being in the triangle, we must find the area of the triangle and the area of the rectangle.

The area of the rectangle can be found by multiplying the width by the height, so the equation would be

8 *4 = 32

The area of the the triangle can be found by the formula A = \frac{1}{2} bh

This means that the equation would look like

\frac{1}{2} *2*4=4

Now that we have both the area of the triangle and the rectangle, we can create a ration of the area of the triangle to that of the rectangle. It would look like this

\frac{4}{32}

This would simplify to \frac{1}{8}

Solve for x, x^2-3x-5=0
Sophie [7]

Okay so for this one, we have to isolate our X.Lets start by moving the negative 5 on the other side of the equal sign. Remember to not mix a number that is with an X with a normal number (in this case it would be the -3x and the -5). So in putting our -5 on the other sign it becomes positive. Here’s what we have: x^2-3x=5. x^2 is the same thing as 2x.So now you have to minus 3x off of your 2x. This gives us -1x, but can just be put as -x. So now we have -x=5. You’re answer could either be 5 or -5 if you decided to divide it by -1 seeing as your -x is technically -1.
