Answer:
{-5,-4,2,4}
Step-by-step explanation:
the domain is which x-values are included so use each of the x-values for each pair. Make sure if there are reapeats that you only write them once.
Solution :
Amounts spent on a trip : $31.11, $25.01, $18.53, $14.37, $24.16, $21.91
Confidence interval = 80%
Average amount spent = 8 to 9 years old
One sample T confidence interval
μ : Mean of variance
80% of confidence interval results :
Using statistical software,
Variable : data
Sample mean : 22.515
Std. Err. = 2.3479945
DF = 5
L. limit : 19.049632
U. Limit : 25.980368
SD = 5.75
Critical value = 1.476
a=-2, b=3, c=-4, d=5
abc-d
abc means multiply those 3 together
so -2 x 3 x -4 = 24
24-5 = 19
answer is 19
Let's solve your equation step-by-step.
4(x−3)−5(x+1)=3
Step 1: Simplify both sides of the equation.
4(x−3)−5(x+1)=3
(4)(x)+(4)(−3)+(−5)(x)+(−5)(1)=3(Distribute)
4x+−12+−5x+−5=3
(4x+−5x)+(−12+−5)=3(Combine Like Terms)
−x+−17=3
−x−17=3
Step 2: Add 17 to both sides.
−x−17+17=3+17
−x=20
Step 3: Divide both sides by -1.
−x−1=20−1
x=−20
