Answer:
n=0
Step-by-step explanation:
Let's solve your equation step-by-step.
3(−10n+9)−3(1+8n)=24
Step 1: Simplify both sides of the equation.
3(−10n+9)−3(1+8n)=24
(3)(−10n)+(3)(9)+(−3)(1)+(−3)(8n)=24(Distribute)
−30n+27+−3+−24n=24
(−30n+−24n)+(27+−3)=24(Combine Like Terms)
−54n+24=24
−54n+24=24
Step 2: Subtract 24 from both sides.
−54n+24−24=24−24
−54n=0
Step 3: Divide both sides by -54.
−54n/-54=0/−54

Answer:
n=0
The proportion in the tail with regards to the z scores will be:
- z = 1.00 = 0.1587
- z = 0.50 = 0.3085
- z = -1.25 = 0.1056
- z = -0.40 = 0.3446
<h3>How to calculate the values?</h3>
a. z= 1.00
P(z > 1.00) = 1 - P(Z < 1.00)
= 1 - 0.8413
= 0.1587
The tail will be on the right side.
The proportion of the tail will be 0.1587.
b. z = 0.50
P(z > 0.50) = 1 - P(Z < 0.50)
= 1 - 0.6915
= 0.3085
The tail will be on the right side.
The proportion of the tail will be 0.3085
c. z= -1.25
P(z < -1.25)
= 0.1056
The tail will be on the left side.
The proportion of the tail will be 0.1056.
d. z= -0.40
P(z < -0.40)
= 0.3446
The tail will be on the left side.
The proportion of the tail will be 0.3446.

Answer:
x = 1
Step-by-step explanation:
9x−4=2x+3 Move all terms containing x to the left side of the equation.
7x−4=3 Move all terms not containing x to the right side of the equation.
7x=7 Divide each term by 7 and simplify. x = 1
Answer:
the answer is -6+-8
Step-by-step explanation:
negative -6+-8 equals -14. If -6 +8 then it will not equal -14. so both signs of the equation have to be negative for the answer to be a negative number.
3/8. To get this answer you need to multiply the numerators and the denominators. 1 x 3 is equal to 3 and 2 x 4 is qual to 8. Therefore, 3/8
