No all triangles have right angle a right angle is a angle measurement of 90 degrees. some triangles are equal sides yes like 60 degrees on each angle. and the angle must equal 180 degrees. not 360 that is a whole different shape.

Not all triangles have right angles. A triangle is simply a closed figure with three sides and three angles, the sum of the degrees of which add up to 180°.

For instance, an equilateral triangle will will have all three angles equal to each other (60°, 60°, 60<span>°).

Some triangles may have right angles (90</span><span>°), but not all do.

A package of 5 pairs of socks costs $35.95. What is the unit price of the pairs of socks?

Juliette [100K]

Answer:

7.19 a pair

Step-by-step explanation:

To find unit price divide the total by the amount

for ex

5 pairs cost 35.95 so 35.95 is the price of 5 pairs. To find out the price of 1 pair divide the price by the items or the 5 pairs of socks. 35.95 / 5 is 7.19

im sorry for my lack of knowing how to explain :(

g Consider writing onto a computer disk and then sending it through a certifier that counts the number of missing pulses. Suppos

Answer:

a) P(1) = 0.1637

b) $P(x\geq 2) = 0.0176$

c) E(x) = 0.2

Step-by-step explanation:

If X follows a poisson distribution, the probability that a disk has exactly x missing pulses is:

$P(x)=\frac{e^{-m}*m^x}{x!}$

Where m is the mean and it is equal to the value of lambda. So, replacing the value of m by 0.2, we get that the probability that a disk has exactly one missing pulse is equal to:

$P(1)=\frac{e^{-0.2}*0.2^1}{1!}=0.1637$
