Answer:

x° = (75/3)°

Right Triangle (scalene)

Step-by-step explanation:

Since this is a right triangle, the other 2 non-right angles add up to 90°:

180° - 90° = 90°

so you get:

(2x+15)° + (x)° = 90°

Solve the equation and find x:

3x° + 15° = 90°

3x° = 75°

x° = (75/3)°

Answer:

Step-by-step explanation:

The measure of the chord- chord angle ABC is half the sum of the arcs intercepted by the angle and its vertical angle, that is

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Burka [1]

Answer: d) 0.9693

<u>Step-by-step explanation:</u>

refer to the z-table attached.

The table shows the percent from the MEAN. The percent below the mean is 50% so that needs to be added to the value in the table.

Look on the left side for 1.8 and the top for 0.07 (which is 1.87).

The value is 0.4693 --> add 0.5 to that value to get 0.9693.

The probability that an egg on a production line is cracked is 0.01. Two eggs are selected at random from the production line. F

musickatia [10]

Answer:

$P(X \geq 1)=1-P(X$

$P(X=0)=(2C0)(0.01)^0 (1-0.01)^{2-0}=0.9801$

And replacing we got:

$P(X \geq 1) = 1-0.9801 = 0.0199$

Step-by-step explanation:

Let X the random variable of interest "number of craked eggs", on this case we now that:

$X \sim Binom(n=2, p=0.01)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we want to find this probability:

$P(x \geq 1)=1-P(X$

And we can find the probability:

$P(X=0)=(2C0)(0.01)^0 (1-0.01)^{2-0}=0.9801$

And replacing we got:

$P(X \geq 1) = 1-0.9801 = 0.0199$
