Answer:

$\sqrt{80}$

80 is the number in the square root

Step-by-step explanation:

$d = \sqrt{(x_{2}-x_{1} )^{2} +(y_{2}-y_{1} )^{2} } \\d = \sqrt{(4-(-4) )^{2} +(5- 1 )^{2} }\\d = \sqrt{(4+4 )^{2} +4^{2}\\d = \sqrt{8^{2} +4^{2} }\\d=\sqrt{64 +16}\\d=\sqrt{80}$

assume that random guesses are made for 8 multiple choice questions on an SAT test, so that there are n=9 trials, each with prob

melamori03 [73]

Answer:

$P(x$

Step-by-step explanation:

If we call x the number of correct questions obtained in the 9 attempts, then:

x is a discrete random variable that can be modeled by a binomial probability distribution p, with n = 9 trials.

So, the p of x successes has the following formula.

$P(x) =\frac{n!}{x!(n-x)!}*p^x(1-p)^{n-x}$

Where:

n = 9

p = 0.6

We are looking for P(x<4)

By definition:

$P(x$

Then:

$P(x\leq3)=\sum_{x=0}^{3} \frac{9!}{x!(9-x)!}*(0.6)^x(1-0.6)^{9-x}$

$P(x\leq3)=0.0994$

The difference of 4 times a number and 7 is 13

vekshin1

I believe the answer is either 5 or -1.5

4n - 7 = 13
7 - 4n = 13

4(5) - 7 = 13
7 - 4(-1.5) = 13

4(5) - 7 = 13
