Total children = 6
1) Probability of 4 girls =4/6=0.66
Probability of at least 4 girls >_ 0.66

That is greater or equal to 0.66


2) probability of 5 girls = 5/ total children
=5/6=0.83
Probability of at most 5 girls <_ 0.83
That is less than equal to 0.83

The circumference of a circle is 604 cm. What is the diameter of the circle?
Marta_Voda [28]

Step-by-step explanation:

The Circumference is:

c = 2\pi \: r

Radius r is:

r =  \frac{d}{2}

So,

c = \pi \: d \\ d =  \frac{c}{\pi}  \\ d =  \frac{604}{\pi} \:  cm

F(x) = x ^ 2 . What is g(x) ?
Bond [772]

Given:

The function is:

f(x)=x^2

The graphs of functions f(x) and g(x).

To find:

The function g(x).

Solution:

We have,

f(x)=x^2

The function f(x) is vertically compresses to get the graph of the function g(x). So, the function g(x) is:

g(x)=kf(x)

g(x)=kx^2               ...(i)

From the given graph it is clear that the graph of the function g(x) passes through the point (3,3). So, putting x=3 and g(x)=3 in the above function, we get

3=k(3)^2

3=9k

\dfrac{3}{9}=k

\dfrac{1}{3}=k

Putting k=\dfrac{1}{3} in (i), we get

g(x)=\dfrac{1}{3}x^2

Therefore, the correct option is D.

Please help me with this question. I am very confused.

I think u do the ones in the parenthesis first bc of PEMDAS since it's both negative it become positive and u can cross out both the 2's and that leaves u with 1/7 and then u just times 1/7 with 8 and then u get 8/7
