Answer:

x = 180 - (37 + 53)

Step-by-step explanation:

x + 37 + 53 = 180

x = 180 - (37 + 53)

All of the angles have to equal 180 due to the supplementary angles thm

if records indicate that 2 houses out of 1000 are expected to be damaged by fire in any year, what is the probability that a wom
blsea [12.9K]

Given that there will be 14 fires in a year, there will be an expected number of fires. There are more than 1000 points available in this question. We must determine the probability that a woman owned.

In a year, a fire will harm one in 12 homes. That is, given if n is equal to 12 and that the value of x is equal to 1, the probability of x being equal to 1 is also equal to 1. Hence, due to fire damage. We discovered that the probability value p equals 0.014, and we are aware that, in general, binomial probability, or the probability that x equals x, is equal to c x, p to the power of x times q to the power of n minus x. Substituting all of these values into the formula, where q = 1 - p, gives us the value of 12 c 1, or 0.014. The total power of 1 for q is 1 minus p, or 1 minus 0.014. 11 points is the power of 12 as a whole less 1. The result of simplification is 0.143865, so Therefore, we have determined that the likelihood of one out of every twelve homes experiencing fire damage is 0.143865 percent.

What is the solution to the equation 4(3x - 11) + 23 = 5x - 14 ?
Maurinko [17]
Hello there!

4(3x - 11) + 23 = 5x - 14

Apply the distributive property to 4(3x - 11)
4(3x) + 4(-11)
12x - 44

We now have:
12x - 44 + 23 = 5x - 14
Combine like-terms on the left-hand side of the equation.
-44 + 23 = -21

12x - 21 = 5x - 14
Get x on one side by subtracting 5x from both sides..
12x - 5x = 7x
5x - 5x = 0

7x - 21 = -14
Add 21 to both sides to isolate 7x.
-21 + 21 = 0
-14 + 21 = 7

7x = 7
Divide both sides by 7 to solve for x.
7x / 7 = x
7 / 7 = 1

We are now left with the following solution:
x = 1

I hope this helps!

A rubber bouncy ball is dropped from a height
vfiekz [6]

Answer:

0.0000571

Step-by-step explanation:

Height after 9th bounce = Initial height * (19/100)^9

                                        = 177*(0.19)^9

                                        = 0.00005711572

Which ordered pair is the best estimate for the solution of the system of equations?
Rasek [7]

Answer:

<u>The ordered pair of the solution is (0.022, -0.55). None of the alternatives given we can consider as the best estimate because there isn't at least one positive value for x, when it's actually positive. Picking (0, -2) as the best estimate is also far from the best estimate.</u>

Step-by-step explanation:

Let's solve the system of equations:

y = −25x

−2y = 5x+1

***********************

Substituting y in the 2nd equation:

-2 (-25x) = 5x + 1

50x = 5x + 1

45x = 1

x = 1/45

x = 0.022

**********************

Solving for y in the 1st equation:

y = -25 (0.022)

y = - 0.55

<u>The ordered pair of the solution is (0.022, -0.55). None of the alternatives given we can consider as the best estimate because there isn't at least one positive value for x, when it's actually positive. Picking (0, -2) as the best estimate is also far from the best estimate.</u>
