The numerator of a rational number 8 ​

Mathematics
1 answer:
exis [7]3 years ago
8 0

Answer:

We conclude that the numerator of a rational number 8 will be 8.

Step-by-step explanation:

We know that any number which can be written in the form p/q is called a rational number.

i.e. p/q

Where p and q are integers and q≠0.

Here:

  • The numerator is p
  • The denominator is q

Given the number

8

As number '8' can be written in the form p/q, so it is a rational number.

i.e. 8/1

Thus,

  • The numerator = 8
  • The denominator = 1

Therefore, we conclude that the numerator of a rational number 8 will be 8.

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the di
Olin [163]

Solution: We are given:

ACT scores follow normal distribution with \mu=20.9,\sigma =4.8

SAT scores follow normal distribution with \mu=1026,\sigma=209

Now, let's find the z score corresponding to Joe's SAT score 1351.

z=\frac{x-\mu}{\sigma}

        =\frac{1351-1026}{209}

        =\frac{325}{209}

        =1.56

Therefore, Joe's SAT score is 1.56 standard deviations above the mean.

Now, we have find the Joe's ACT score, which will be 1.56 standard deviations above the mean.

Therefore, we have:

z=\frac{x-\mu}{\sigma}

1.56=\frac{x-20.9}{4.8}

1.56 \times 4.8 = x - 20.9

7.488=x-20.9

x=20.9+7.488

x=28.388 \approx 28.4

Therefore, Joe's equivalent ACT score to SAT score 1351 is 28.4

Solve the system:<br> 5y+8(x−3y)=7x−12 <br> 9x+3(x−9y)=11y+46
Pie

Answer:

5y+8(x-3y)=7x-12

5y+8x-24y=7x-12

8x-7x + 5y-24y= -12

X - 19y = - 12

9x+3(x-9y) =11y+46

9x+3x - 27y = 11y + 46

12x -27y - 11y = 46

12x - 38y = 46

Now joining together

X - 19y = - 12

12x - 38y = 46

Multiple by 12 the first equation and Substract after

12x - 228y = -144

12x - 38y = 46

- 190y = -98

Y = 1.9

12x - 38y = 46

12x - 38(1.9) = 46

12x - 73.67 = 46

12x = 46 + 73.67

12x = 119.67

X = 9.97

So the answer are :

X = 9.97

Y = 1.9
