Answer 1

Answer:

D

Step-by-step explanation:

7 - z = 3 + z + 4 - 2z

7 - 3 - 4 = z - 2z + z

0 = 0 (Infinitely many solutions)

5(a + 4) - 15 = -5(a - 1)

5a + 20 - 15 = -5a + 5

5a + 5a = 5 - 20 + 15

10a = 40

10a/10 = 40

a = 4

(one solution)

-2d + 4d - 4 = 5 + 3(d - 3)

2d - 4 = 5 + 3d - 9

2d - 3d = 5 - 9 + 4

- d = 0

d = 0

(one solution)

-11(n - 2) + 8(n + 1) = -3(n + 10)

-11n + 22 + 8n + 8 = -3n - 30

-11n + 8n + 3n = -30 - 22 - 8

0 = -60

(no solutions)

6x^2-5x-4=0
solving quadratics by factoring (answer with {} around it)

Answers

Step-by-step explanation:

6x²–5x–4 = 0

6×4 = 24..

write many ways 24 can be written..

24 = (6×4), (1×24), (12×2), (8×3)

(8×3) --> –8+3 = –5

6x²+3x–8x–4 = 0

6x(x+½)–8(x+½) = 0

(6x–8)(x+½) = 0

6x–8 = 0, x+½ = 0

6x = 8, x = –½

x = 4/3, –½

In a certain state, a survey of 600 workers showed that 35% belonged to a union. Find the 95% confidence interval of true proportion of workers who belong to a union.

Answers

Answer:

The 95% confidence interval of true proportion of workers who belong to a union.

(0.29657 , 0.40343)

Step-by-step explanation:

Explanation:-

Given sample size 'n' = 600

Given sample proportion  p = 35% or 0.35

The 95% confidence interval of true proportion of workers who belong to a union.

[tex](p^{-} -Z_{0.05} \sqrt{\frac{pq}{n} } , p^{-} + Z_{0.05} \sqrt{\frac{pq}{n} } )[/tex]

[tex](0.35 -1.96\sqrt{\frac{0.35 X0.65}{600} } , 0.35 + 1.96\sqrt{\frac{0.35 X 0.65}{600} } )[/tex]

( 0.35 - 1.96 (0.02726) , 0.35 + 1.96 (0.02726)

(0.35 - 0.05343 , 0.35 + 0.05343)

(0.29657 , 0.40343)

Final answer:-

The 95% confidence interval of true proportion of workers who belong to a union.

(0.29657 , 0.40343)

what is 4855/200 simplified

Answers

Answer:

The answer is 2427.5

Step-by-step explanation:

The fraction consists of two numbers and a fraction bar: 4,855/200

The number above the bar is called numerator: 4,855

The number below the bar is called denominator: 200

The fraction bar means that the two numbers are dividing themselves.

To get fraction's value divide the numerator by the denominator:

Value = 4,855 ÷ 200

To calculate the greatest common factor, GCF:

1. Build the prime factorizations of the numerator and denominator.

2. Multiply all the common prime factors, by the lowest exponents.

Factor both the numerator and denominator, break them down to prime factors:

Prime Factorization of a number: finding the prime numbers that multiply together to make that number.

4,855 = 5 × 971;

4,855 is a composite number;

In exponential notation:

200 = 2 × 2 × 2 × 5 × 5 = 23 × 52;

200 is a composite number;

The slope of the line is 2.

The slope is going up from left to right, so it'll be positive to start with. From there you have to do rise over run. That is pretty much how many units up and in towards the slope do you have to go until you find 2 points that are in the center of the line. In this case, the rise over run is 2/1 which equals 2.
