<span>In the binomial experiment, the number of times the six-sided cube was rolled is the number of trials. Thus the number of trials for this binomial experiment is 12. The formular for a binomial experiment is nCx (p)^x (q)^(n - x) where: n is the number of trials, x is the success event, p is the probability of success, q is the probability of failure.</span>

C. 12

Sonia rolls it 12 times, so there's 12 trials.

andrezito [222]

Answer:

The minimum number of words left to write is 215

Step-by-step explanation:

Let

w -----> the number of words left to write

we know that

The number of words left to write plus the words written so far must be greater than or equal to 500 words

Remember that the word "at least" means "greater than or equal to"

so

w+285\geq 500                

Solve for w                        

Subtract 285 both sides        

w\geq 500-285\\w\geq 215

The minimum number of words left to write is 215

Mr.Walden wrote the expression. He asked his students to write an equivalent expression of simplified form.
mafiozo [28]

Answer:

option D

Brianna

Step-by-step explanation:

Given in the question the expression wrote by Mr.Walden

\frac{p^{-5} }{q^{0} }

To write the simplified form of this expression we will use negative rule of exponent

b^{-n}= 1 / b^{n}

q^{-5} = \frac{1}{q^{5} }

so,

\frac{1}{q^{5} x q^{0} }

\frac{1}{q^{5} p^{0} }

Only Brianna wrote right simplification of the expression written by Mr.Walden

A machine needs 2 of its gears replaced. You find 2 gears, one manufactured 5 years ago and the other manufactured 10 years ago.
Tcecarenko [31]
Probability that gear 1 will fail = 5/100 (upto 10 years) 
and 8/100 (after 10 years)

Probability that both will fail = 5/100 * 8/100
= 40/10000
= 0.4 %

Which statement is true about the graphed function
natka813 [3]

From -∞ to -4 the blue line is above the X axis which means it is >0

The blue line is negative between -4 and -3


This would make the correct answer: F(x) > 0 over the interval (-∞,-4)
