-30-5x=-4x-6(5+4x)

First, you need to use the distributive property on the right to get -30-5x=-4x-30-24x

Then, you can add like terms to get -30-5x=-30-28x

Then, you can add 30 to both sides and add 5x to both sides to get 0=-23x

Finally, you divide both sides by -23 to get 0=x

Answer:

A) H1: π < 0.10

Step-by-step explanation:

One tailed test:-

A test of any statistical hypothesis where the alternative hypothesis is one tailed ( right tailed or left tailed) is called a one - tailed test.

H1: μ < μ0 (left tailed test)

H1: μ > μ0 (right tailed test)

two tailed test:-

In a test of statistical hypothesis where the alternative hypothesis is two tailed , we assume that the null hypothesis

H0: μ = μ0 against the alternative hypothesis

H1: μ ≠ μ0

conclusion:-

given data It is claimed that in a bushel of peaches, fewer than 10% are defective so alternative hypothesis

H1: μ < 0.10

Answer:

Step-by-step explanation:

4- 3*1=3

6*1/100= 0.06

3+0.06= 3.06

5- 7*1= 7

3*1/10= 0.3

4*1/1,000= 0.004

7+0.3+0.004= 7.304

7- 3.3, 3.30

8- 9.3000, 9.30

9- 9.6, 9.600

10- 4.4000, 4.40

for #4-5 just put the number of 0s in the denominator of the fraction for the answer

If f(x)=x^2+2x-3 and g(x)=x^2-9, find (f/g)(4) and (f+g)(4)

Likurg_2 [28]

Answer:

Part 1: Find (f/g)(4) = 3

Part 2: Find (f+g)(4) = 28

Step-by-step explanation:

Part 1: Find (f/g)(4):

(f/g)(4) means divide f function by g function and simplify it. Then plug in 4 into x of that simplified function.

Let's do this:

$\frac{x^2+2x-3}{x^2-9}\\=\frac{(x+3)(x-1)}{(x-3)(x+3)}\\=\frac{x-1}{x-3}$

Plugging in 4 into x gives us:

$\frac{x-1}{x-3}\\=\frac{4-1}{4-3}\\=\frac{3}{1}\\=3$

The answer is 3

Part 2: Find (f+g)(4):

(f+g)(4) means add f function and g function and simplify it. Then plug in 4 into x of that simplified function.

Let's do this:

$(x^2+2x-3)+(x^2-9)\\=2x^2+2x-12$

Plugging in 4 into x gives us:

$2x^2+2x-12\\=2(4)^2+2(4)-12\\=28$

The answer is 28
