A private school determines their annual profits from the function
p(x) = 0.4x2 – 19x, where x is the number of students enrolled in the school. What is
the annual profit if 750 students are enrolled in the school? 100 POINTS!!!

Answer:

Step-by-step explanation: look at the picture

1. No correlation

Those things don't really relate to each other.

2. Positive correlation

The more you drive your car, the more you'll have to pay for gas.

3. Negative correlation

More people = less soda.

Answer:

CI = ( 0, 042 ;  0,079 )

Step-by-step explanation:

If from 884 , 831  disks were OK  then  884  - 831  = 53 were defective

x  =  53

p = 53/884    p  = 0,0599     or p = 5,99 %   p ≈ 6 %

and q =  1  - 0,06       q = 0,94

p*n  and q*n   are big enough

For CI 98 %  significance level is α = 2 %   α/2 = 0,01

z(score) for α/2 = 0,01 is

z(c) ≈ 2,324

CI  =  p ±  z(c) *√p*q/n

√p*q/n   =  √ ( 0,94*0,06)/884

√p*q/n   =  √ 0,0564/884

√p*q/n   =  0,00799

CI  =  ( 0,06  ±  2,324*0,00799)

CI  =  ( 0,06  - 0,0185 ; 0,06 +  0,0185 )

CI = ( 0, 042 ;  0,079 )

Answer:

The ratio of approved and disapproved people in its simplest form is 3:1.

Step-by-step explanation:

Since 81 people passed and 27 failed their Functional Skills Level 2 exams, to write this as a ratio in its simplest form, the common greatest divisor of both numbers must be obtained:

27 is divisible by 1, 3, 9 and 27

81 is divisible by 1, 3, 9, 27 and 81

Therefore, the common greatest divisor of both numbers is 27. So, since 27/27 is equal to 1, and 81/27 is equal to 3, the ratio of approved and disapproved people in its simplest form is 3 :1.

The ratio in its simplest form is 1 : 3.

Ratio expresses the relationship between two numbers. It is the frequency with which a number is contained in another number. The sign used to represent ratio is ':'.

In order to express the given number of people that passed and failed the exam, we have to divide both numbers by the highest common factor until both numbers cannot be divided further to yield a whole number.

Common factor of 27 and 81 = 1, 3, 9, 27

Highest common factor = 27

Expressing in the simplest form = 1 : 3

Answer: x = -20

Step-by-step explanation:

Question: If -x = 20, then x = ?

Multiply both sides of the equation by -1

(-1)(-x) = (-1)(20)

Simplify (remember that multiplying two negative numbers equals a positive number)

x = -20

Answer:

The line is a vertical line, which does not have a slope.

Step-by-step explanation:

Slope of a line:

Suppose we are given two points in the format (x,y) of a line. The slope is given by the change in y divided by the change in x.

(6,6) and (6, -7).

Change in y: -7 - 6 = -13

Change in x: 6 - 6 = 0

Slope is a division by 0, which means that the line is a vertical line, which does not have a slope.

Answer:

7.48m (3s.f.)

Step-by-step explanation:

Let the missing side be x m.

Applying Pythagoras' Theorem,

x² +5²= 9²

x² +25= 81

x²= 81 -25 (-25 on both sides)

x²= 56

[tex]x = \sqrt{56} [/tex]

[tex]x = 2 \sqrt{14} [/tex]

x= 7.48 (3 s.f.)

∴ The missing side is 7.48 m (3s.f.)

Answer:

550 N

Step-by-step explanation:

We can solve the problem by using Newton's second law:

[tex]F=ma[/tex]

F is the force required to accelerate the car

m is the mass of the car

a is the acceleration of the car

In this problem, the mass is m=1100 kg, while the acceleration is a=0.5 m/s^2, therefore the force required to accelerate the car is

[tex]F=ma=(1100kg)(0.5m/s^{2} )=550N[/tex]
