Answer:

D. x = 1.7 or x = 5.7

Step-by-step explanation:

The left side of the equation is graphed in blue. The right side of the equation is graphed in red.

The solution of the equation is the x (and y) that make both equations true.

On the graph these solutions are the points where the two graphs intersect.

Those two points have x values that are positive (and y's that are negative) Only answer D. has x-values that correspond to the x-values of the points of intersection.

Answer: 0.5898

Step-by-step explanation:

Given : J.J. Redick of the Los Angeles Clippers had a free throw shooting percentage of 0.901 .

We assume that,

The probability that .J. Redick makes any given free throw =0.901 (1)

Free throws are independent.

So it is a binomial distribution .

Using binomial probability formula, the probability of getting success in x trials :

$P(X=x)^nC_xp^x(1-p)^{n-x}$

, where n= total trials

p= probability of getting in each trial.

Let x be binomial variable that represents the number of a=makes.

n= 14

p= 0.901 (from (1))

The probability that he makes at least 13 of them will be :-

$P(x\geq13)=P(x=13)+P(x=14)$

$=^{14}C_{13}(0.901)^{13}(1-0.901)^1+^{14}C_{14}(0.901)^{14}(1-0.901)^0\\\\=(14)(0.901)^{13}(0.099)+(1)(0.901)^{14}\ \ [\because\ ^nC_n=1\ \&\ ^nC_{n-1}=n ]\\\\\approx0.3574+0.2324=0.5898$

∴ The required probability = 0.5898

-5(2 – 5n) + 6 = -5n - 34 -02

statuscvo [17]

Answer:

Assuming you're solving for n, 1. n=-1 2. n=-1.6

Step-by-step explanation:

1. -5(2-5n)+6=-5n-34-2

Distributive Property

-10+25n+6=-5n-32-2

Add Like Terms

-4+25n=-5n-34

Subtract -4

25n=-5n-30

Subtract -5n

30n=-30

Divide by 30

n=-1

2. -5(2-5n)+6=-5n-34-20

Distributive Property

-10+25n+6=-5n-32-20

Add Like Terms

-4+25n=-5n-52

Subtract -4

25n=-5n-48

Subtract -5n

30n=-48

Divide by 30

n=-1.6
