Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0  

Discriminant = 4 - 4(K)(-1) = 4 + 4K  

For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.  

The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.

On a test that has a normal distribution, a score of 60 falls two standard deviations above the mean, and a score of 42 falls on
Sergeu [11.5K]

Answer:

48

Step-by-step explanation:

Given that:

A  \ score  \ of \  60  \ falls \  two  \ standard   \ deviations \  above \  the \ mean \\ \\ A \  score \ of \ 42  \ falls \  one  \ standard  \ deviation \ below  \ the \ m ean

The interval for score = 60 - 42 = 18

If we divide it by the 3 standard deviations; the interval result into

= 18/3

= 6

So, the standard deviation is 6, and the mean = 42 + 6

= 48

Maths people please write the answers !<br><br><br> Equations- Maths
Korvikt [17]

Answer:

length = 20cm

breadth = 8cm

Step-by-step explanation:

solution;

length(l) = x + 12

breadth(b) = x

perimeter (p) = 56 cm

we know that,

perimeter(p) = 2(l + b)

or, 56 = 2(x + 12 + x)

or, 56 = 2(2x + 12)

or, 56 = 4x +24

or, 56 - 24 = 4x

or, 32 = 4x

or, 32 / 4 = x

x = 8

now

putting the value of x in length and breadth

length = x+ 12

=8 + 12

=20cm

breadth = 8cm
