The five patterns are: circle, plus sign, wavy lines, empty box, and star. One hundred trials were conducted, and your very impr

essive friend guessed right on 41 of those trials. What proportion of the cards would I expect my friend to guess correctly?

Answer:

The proportion is \frac{41}{100} = 0.41 or 41%

Step-by-step explanation:

Hello!

The expected proportion is calculated as "the number the event of interest has occurred"(i.e. success) divided the total of trials.

In this case, your success is the number of times your friend guessed a card correctly in 100 trials.

The proportion is \frac{41}{100} = 0.41 or 41%

I hope it helps!

F(x)= (x+2)^2 -1<br> Find x intercept <br> Find y intercept<br> Find vertex
Trava [24]
The x intercept occurs when y = 0.

0=(x+2)^2 - 1
1=(x+2)^2

Take the square root of both sides. Note that the sqrt of 1 is 1. Then solve for x.

1=x+2
-1=x

The x intercept is -1.

The y intercept occurs when x=0.

y=(0+2)^2 - 1
y=2^2 -1
y=4-1
y=3

The y intercept is 3.

Now, to find the vertex...

This parabola is currently in a format called the vertex form, which is:

f(x) = (x-h)^2 + k

where (h, k) is the vertex.

Therefore, the vertex is (-2, -1).

The function h is a quadratic function whose graph is a translation 3 units left and 4 units up of the parent
jeka57 [31]

Answer:

D ( if you add +4 to the (x + 3)^2)

Step-by-step explanation:

Parent function is f(x) = x^2

A translation 3 units left gives y = )x + 3)^2

- and 4 up gives y = (x + 3)^2 + 4 - vertex form.

Standard form :

y = x^2 + 6x + 9 + 4

= x^2 + 6x + 13.
