Find the value of C that completes the two way frequency table below: *

Tanya [424]

Answer:

A = 16

B = 14

C = 34

Step-by-step explanation:

If we start with trying to find A, then we would add these numbers together:

2+ 14 = 16

A = 16

Now that we have the total for part A, we can add the bottom row:

16+18 = 34

C = 34

Another way to find C is to first solve for the value of B which can be worked out as follows:

2+12 = 14

B = 14

Then we would add all the totals on the right to get the grand total of men and women in the sample:

14+20 = 34

C = 34

Hope this Helps!

Here is the sample space for three tosses of a coin.

BARSIC [14]

Assuming the coin is fair, the probability of the coin toss resulting in H is $p=\dfrac12$ . So the probability of getting two Hs, in any order, is

$\dbinom32p^2(1-p)=\dfrac38=0.375$

If the graph of f(x)= x^2+10x+k has two distinct zeros, find the value of k

V125BC [204]

Answer:

The value of k must be less than 25

Step-by-step explanation:

we have

$f(x)=x^2+10x+k$

we know that

If the discriminant of a quadratic function is greater than zero, then the function has two distinct zeros

The discriminant D is equal to

$D=b^2-4ac$

we have

$a=1\\b=10\\c=k$

$D=10^2-4(1)(k)\\D=100-4k$

Remember that

$D> 0$

$100-4k> 0$

solve for k

$-4k> -100$

Divide by -4 both sides

$k< 25$

therefore

The value of k must be less than 25
