Which equation represents h(x)?

GarryVolchara [31]

Answer:

Step-by-step explanation:

You might find this easier if you change h(x) to y. It might look more familiar.

you are given 1 point and that is (-1,1). What that means is when x = -1,

y = 1

You have written this as though y is linear. It is not. The power is 1/3, not 1.

Let us try B which is what I think the answer is.

y = (x + 2)^(1/3)

Put x = -1 on the right hand side.

y = (-1 + 2)^(1/3)

y = (1)^(1/3)

The cube root of 1 is 1.

So the answer is

y = (x + 2)^(1/3)

Answer:

0.01083 or 1.083%

Step-by-step explanation:

This problem can be modeled as a binomial probability model with probability of success p = 0.56.

The probability of x=13 successes (a college student being very confident their major would lead to a good job) in a number of trials of n=15 is:

$P(X=x) = \frac{n!}{(n-x)!x!} *p^x*(1-p)^{n-x}\\P(X=13) = \frac{15!}{(15-13)!13!} *0.56^{13}*(1-0.56)^{15-13}\\P(X=13) = 0.01083=1.083\%$

The probability is 0.01083 or 1.083%.

i didnt understand the question because of my English sorry

we all know that the total of degrees is 180 so 70+70=140

180-140=40

so the answer is 40

we have a figure with 4 angle so the total of degrees is 360 so the answer is 126

the answer most be 50 becuse we have a Special degree witch always equal 90 if we have recatngle so

x+40=90

X=50 the answer and if you want to try again choose the second one

2x-10=90

2x=100

X=50 same answe you see

in this quastion i searched and find alot of answers any way

its should be 7 or 3 but the correct answer in my opinion its 7

its shows in the picture i sent hopefully its helpful to you i will try to translate the first quastion and sent it to you
