Answer:

(x-3)(x-10)

Step-by-step explanation:

To factor the equation, break it into two binomials which multiply to make the equation. To write these binomials (x+a)(x+b), find factors which multiply to 30 and add to -13 for a and b.

30: 1, 2, 3, 5, 6, 10, 15, 30

-3+-10 = -13

x^2-13x+30 = (x-3)(x-10)

PLEASE HELP! 8 POINTS!! Find the value
Pepsi [2]

Answer:

-sqrt(3)/2

Step-by-step explanation:

Use double angle identity for sin(2x)

sin(2x)=2sin(x)cos(x)

We are given sin(x)=-1/2 so we already have so far that:

sin(2x)=2(-1/2)cos(x)

sin(2x)=-1*cos(x)

We just need to find cos(x).  

x is in the fourth quadrant so cosine will be positive there

knowing the unit circle we should know that if sin(x)=-1/2 then cos(x)=sqrt(3)/2 while in 4th quadrant.

So the answer is sin(2x)=-1*sqrt(3)/2=-sqrt(3)/2

Suppose that 76% of americans prefer coke to pepsi. a sample of 80 was taken. what is the probability that at least seventy perc
vladimir2022 [97]
The standard deviation of the sample proportion is:
\sqrt{ \frac{0.76(1-0.76)}{80}} =0.048
The z-score for 0.7 is:
z= \frac{0.7-0.76}{0.048} =-1.25
Reference to a standard normal distribution table shows that the probability that at least 70% of the sample prefers coke to pepsi is 0.8944 or 89.44%.
