Answer:

$60 \: degrees$

Step-by-step explanation:

$180(n - 2)$

you have to put the number of sides for n

$180(n - 2) \\ 180(6 - 2) \\ 180 \times 4 \\ = 720$

720 is the sum of interior angles. so to find the value of an angle you have to divide 720 by the number of angles.

$\frac{720}{6} = 120 \: \: degrees$

we know that,

interior angle + exterior angle = 180 degrees

$120 + z = 180 \\ z = 180 - 120 \\ z = 60 \: \: degrees$

hope this helps

A random variable follows the continuous uniform distribution between 160 and 340. Calculate the following quantities for the di

Firlakuza [10]

Answer:

a) 0.3889

b) 0.5

c) 0.8333

d) The mean is 250 and the standard deviation is 51.96.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability of finding a value of X higher than x is:

$P(X > x) = 1 - \frac{x - a}{b-a}$

The probability of finding a value of X between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The mean and the standard deviation are, respectively:

$M = \frac{a+b}{2}$

$S = \sqrt{\frac{b-a}^{2}{12}}$

A random variable follows the continuous uniform distribution between 160 and 340.

This means that $a = 160, b = 340$

$P(220 \leq X \leq 290) = \frac{290 - 220}{340 - 160} = 0.3889$

$P(160 \leq X \leq 250) = \frac{250 - 160}{340 - 160} = 0.5$

$P(X > 190) = 1 - \frac{190 - 160}{340 - 160} = 0.8333$

$M = \frac{160 + 340}{2} = 250$

$S = \sqrt{\frac{340 - 160}^{2}{12}} = 51.96$

The mean is 250 and the standard deviation is 51.96.

SOMEONE PLEASE HELP....

Anton [14]

Answer:

Step-by-step explanation:

$(3x+4)(x^2+px+5) \\=3x^3+3px^2+15x+4x^2+4px+20\\=3x^3+(3p+4)x^2+(15+4p)x +20$

since we know that $x^2$ in this expansion is $-23x^{2}$

thus $3p+4=-23\\3p=-27\\p=-9$

Hope that helps!

A square pyramid has a height of 6 units and a volume of 70 units3. if a square prism has the same base area and volume as the s

goldfiish [28.3K]

The height of the square pyramid exists 2 units.

<h3>How to estimate the area of the base of the square pyramid?</h3>

Volume of the square pyramid

$$V = \frac{1}{3}BH$

where B exists in the area of the base H lives at the height of the pyramid

we have H = 6 $$$unit^3$

V = 70 $$$unit^3$

substitute in the formula and solve for B, we get

$$70 = \frac{1}{3}B(6)$

B = $$\frac{70}{2}$

= 35 $$$unit^3$

To estimate the height of the square prism

Volume of the square prism = Bh

Where B exists the area of the base

h exists the height of the prism

we have B = 35 and V = 70

substitute in the formula and solve for h

70 = (35)h

h = 2 units.

Answer:

A: Y<1/2x+2

Step-by-step explanation:

The shaded area is under the line, which indicates that Y is less than or equal to. The +2 in the inequality tells you where the y-intercept is (where the line goes through the y-axis). The 1/2 in the inequality tells the slope of the line (up 1, over 2) thus 1/2. So the answer is A
