Answer:

x = 10, y = 40

Step-by-step explanation:

Given the 2 equations

y = 4x → (1)

2y + 2.5x = 105 → (2)

Substitute y = 4x into (2)

2(4x) + 2.5x = 105, that is

8x + 2.5x = 105

10.5x = 105 ( divide both sides by 10.5 )

x = 10

Substitute x = 10 into (1)

y = 4x = 4 × 10 = 40

The pregnancy length in days for a population of new mothers can be approximated by a normal distribution with a mean of 269 day
fenix001 [56]

Answer:

a) 279 b)254

Step-by-step explanation:

Mean = 269 days

standard deviation = 8 days

let n be the pregnancy lenght.  

using normal distribution formula

z = (n – mean)/ standard deviation

n = z * standard deviation + mean

Now, z values for the top 12% has to be found using a z table.

The top 12% means 88% of area under the curve. In this case z = 1,176

n = 1,176 * 8 + 269

n = 278.4 = 279

The bottom 3% means 97% of area under the curve. In this case z = -1,882

n = -1,882 * 8 + 269

n = 253.94 = 254

Suppose that, in some distant part of the universe, there is a star with four orbiting planets . One planet makes a trip around
WINSTONCH [101]

Answer: 90 Earth years.

Step-by-step explanation:

Analizing the information provided in the exercise, you need to find the Least Common Multiple (LCM) of the given numbers.

You can follow these steps:

1. You must descompose 6, 9, 15 and 18 into their prime factors:

6=2*3\\\\9=3*3=3^2\\\\15=3*5\\\\18=2*3*3=2*3^2

2. Finally, you need to choose the commons and non commons with their greatest exponents and multiply them. Then you get:

L.C.M=2*3^2*5=2*9*5\\\\L.C.M=90

Therefore, it will take 90 Earth years for them to all line up.
