Answer:

x = - 6, x = 4

Step-by-step explanation:

Given

x² + 2x - 24 = 0

Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (+ 2)

The factors are + 6 and - 4 , since

6 × - 4 = - 24 and 6 - 4 = + 2 , then

x² + 2x - 24 = (x + 6)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 6 = 0 ⇒ x = - 6

x - 4 = 0 ⇒ x = 4

Answer:

Step-by-step explanation:

(5x3-2x2+1) + (2x2-6x4-5)

(15-2x2+1) + (4-6x4-5)

(13x2+1) + (-2x4-5)

(26+1) + (-8-5)

27 + -13

Hope this helps... I was confused on the question about the decimals this is the best I can do... Have a nice day though! ☺️

Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol (mu, p, sigma) for the i

ValentinkaMS [17]

Answer:

$H_o:\mu = 48\\H_a:\mu\neq48$

Step-by-step explanation:

Given : . The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a true mean temperature, 48°F, ideal for a certain type of German pilsner.

To Find : The owner of the brewery does not agree with the refrigerator manufacturer, and claims he can prove that the true mean temperature is incorrect.

Solution:

We are given that refrigerators that are supposed to maintain a true mean temperature, 48°F.

Claim : The true mean temperature is incorrect.

So, null hypothesis and alternate hypothesis will be :

$H_o:\mu = 48\\H_a:\mu\neq48$

So, Option D is true .

What's the answer?????

Marina CMI [18]

Answer:

Step-by-step explanation:

basically plug a and b back into the equation so (0)÷(48) will equal 0 which is equal to C because 0 out of any number is always equal 0 because you're not taking taking any value out of it
