A building may fail by excessive settlement of the foundation or by collapse of the superstructure. Over the life of the buildin

patriot [66]

Answer:

0.1536

Step-by-step explanation:

The computation of probability that the building failure will occur over its life is shown below:-

P(building failure) is

$P(ES \cup C)\\\\ = P(ES) + P(C) - P(ES\cap C)\\\\ = P(ES) + P(C) - P(ES) P (C | ES)\\\\ = 0.12 + 0.06 - 0.12 \times 0.22$

now we will solve the above equation

= 0.18 - 0.0264

After solving the above equation we will get

= 0.1536

Therefore for computing the probability that the building failure will occur over its life we simply applied the above formula.

When angles are complementary, the sum of their measures is 90 degrees.Two complementary angles have measures of 2x-10 degrees a

Mariana [72]

Complementary angles are those angles whose sum is 90 degree.

The measurement of two complementary angles are

$(2x-10), (3x-10)$

There sum have to be 90 degree. That is

$2x-10+3x-10 = 90$

Combining like terms ,

$5x - 20 = 90$

Moving 20 to right side

$5x=110$

Dividing both sides by 5

$x =22$

So the measurement of the angles are

$2*22-10 , 3*22-10 \\
34 degree, 56 degree$

In February, Alec had 1,586 visitors to his website. In March, he had 1,352 visitors to his website. What is the percentage decr

Deffense [45]

Answer:

The percentage decrease of the number of visitors to Alec's website from February to March is 14.8 %

Step-by-step explanation:

Explanation:

Percent decrease is a measure of percent change, which is the extent to which something loses value.

Step 1:

Find out the difference (decrease) between the number of visitors in march and February

Decrease =number of visitors in Fe bury- Number of vsitors in march

Decrease= 1,586- 1,352

Decrease =234

Step 2:

Divide the decrease by the original number of visitors and multiply the answer by 100.

Percent decrease= $\frac{Decrease }{ Original Number }\times100$

Percent decrease= $\frac{236}{1586}\times100$

Percent decrease= $0.148\times100$

Percent decrease =14.88

I don't kind fast food sells large burgers for five dollars each and french fries for three dollars each that day they sold six

lesya692 [45]

Answer:

They sold 16 French fries.

Step-by-step explanation:

Let x represent the number of large burgers that they sold on that day.

Let y represent the number of French fries that they sold on that day.

fast food sells large burgers for five dollars each and french fries for three dollars each that day and their total sales was $98.It means that

5x + 3y = 98 - - - - - - - - - - - - - -1

they sold six more french fries than burgers. It means that

y = x + 6

Substituting y = x+ 6 into equation 1, it becomes

5x + 3(x + 6) = 98

5x + 3x + 18 = 98

8x = 98 - 18 = 80

x = 80/8 = 10

y = x + 6 = 10 + 6

y = 16
