Which expression has a value that is equivalent to 5n+13 when n= -5
maks197457 [2]

Answer:

Option A is correct.

4n + 8 expression which has a value that is equivalent to 5n+13 when n = -5

Step-by-step explanation:

Given the expression: 5n + 13

If n = -5

then, by substituting in given expression we get;

5(-5)+13 = -25+13 = -12

Option A:

4n + 8

Substitute the value of n = -5 we have;

4(-5) + 8 = -20 + 8 = -12

Option B:

2n + 2

then;

2(-5) + 2 = -10 + 2 = -8

Option C :

n^2+13

then;

(-5)^2+13 = 25 + 13 = 38

Option D:

n + 8

then;

-5 + 8 = 3

Therefore, only option A has expression which has a value that is equivalent to 5n+13 when n = -5

Suppose a random sample of 25 students is selected from a community college where the scores in the final exam (out of 125 point
BartSMP [9]

Answer:

he probability that the sample mean deviates from the population mean = 112 by no more than 4= 0.9050

Step-by-step explanation:

mean = 112

sd = 12/sqrt(25) = 2.4

z = (x - μ)/σ

z = (116 - 112)/2.4 = 1.67

Therefore,

P(X >= 116) = P(z <= (116 - 112)/2.4)

= P(z >= 1.67)

= 1 - 0.9525

= 0.0475

z = (x - μ)/σ

z1 = (108 - 112)/2.4 = -1.67

z2 = (116 - 112)/2.4 = 1.67

Therefore, we get

P(108 <= X <= 116) = P((116 - 112)/2.4) <= z <= (116 - 112)/2.4)

= P(-1.67 <= z <= 1.67) = P(z <= 1.67) - P(z <= -1.67)

= 0.9525 - 0.0475

= 0.9050

Find the length of the missing side. Give your answer in the simplest radical form.
taurus [48]

Answer:

x = 2\sqrt{5}

Step-by-step explanation:

Use Pythagorean theorem,

Hypotenuse² = base² + altitude²

x² = (√8)² + 4²

  =  8 + 16

  = 20

x = √20 = \sqrt{2*2*5} = 2\sqrt{5}

x = 2\sqrt{5}
