Question

Mathematics
1 answer:
deff fn [24]2 years ago
6 0

Answer:

When this runs you would get for each trial:

Child 1: X + (X or Y)

Child 2: X + (X or Y)

Child 3: X + (X or Y)

Child 4: X + (X or Y)

Child 5: X + (X or Y)

Step-by-step explanation:

Well in this scenario we would be looking to see if the gender of the 5 children is going to be a girl or boy. Depending on the situation there is a 50/50 chance you get a XY or XX combinations which determine the gender.

So if the couple plans to have 5 children we would run a simulation that would randomly generate either a X or Y and add it to an X for 5 children. This would be done 120 times to get the desired amount of trials.

Each (X or Y) would be a 50/50 chance probability meaning 1/2 chance to get X and another 1/2 to get Y.

Determine if direct variation x-2y=0
Fofino [41]

Answer:

x-2y=0 is a direct variation

Step-by-step explanation:

Direct variation is of the form

y= kx

Can we get the equation in that form

x-2y =0

Add 2y to each side

x-2y+2y =0_2y

x=2y

Divide each side by 2

x/2 = 2y/2

1/2x =y

Flip the sides

y = 1/2x

This is of the form y= kx where k = 1/2

x-2y=0 is a direct variation

Tina is attempting to factor the expression 10x^2-13-3. In her first step, she rewrites the expression as 10x^2-10x-3x-3. Which
Setler79 [48]

ANSWER

B. The two middle coefficients add to the correct number but do not multiply to the correct number.

EXPLANATION

The given quadratic trinomial that Tina tries to factor is

10 {x}^{2}  - 13x - 3

Comparing to

a{x}^{2}  + bx  + c

we have a=10, b=-13 and c=-3

ac=-3×10=-30

We split the middle term so that their sum is -13.

Tina use

-10,-3

to get

-10x-3x

The sum is -13x alright but the product is not -30.

B is correct.
