Solve the Inequality for x
4x − 5 ≥ 7
Move all terms not containing x to the right side of the inequality.
4x ≥ 12
Divide each term by 4 and simplify.
x ≥ 3
The result can be shown in multiple forms.
Inequality Form:
x ≥ 3
Interval Notation:
[3,∞)
Lots of love for you darling!~ <3
You graph it here
Answer:
Upper limit 150
Lower bond 136
Step-by-step explanation:
Hello!
The study variable is:
X: measurement of IQ of a statistic instructor.
This variable has a normal distribution:
X~N(μ; σ²)
And the population standard deviation is known σ= 16
You need to construct a confidence interval for the population mean, for this, since the variable has a normal distribution and the population variance is known, the statistic to use is the standard normal
Z= X[bar] - μ ~N(0;1)
σ/√n
The formula for the interval is:
X[bar] ± *
Where
X[bar] is the sample mean
is the value under the Z distribution for the corresponding confidence level.
S is the population standard deviation. (should be sigma but it doesn't recognize the symbol)
[143 ± 1.96 * ]
[135,988; 150. 012] ≅ [136; 150]
I hope it helps!
I see you accidentally pasted the expression 2(4x-3)+3x-1 twice, so
expand 2(4x-3) to get
2(4x)+2(-3)=8x-6
now we have
8x-6+3x-1
regrouping we get
8x+3x-6-1
adding like terms
11x-7
A is 11x-4, not 11x-7, wrong
B is wrong
C. hmm, 6x-6+5x-1=11x-7, yep
D is the same, we can see
C and D are correct
You answer is 12 because that is where on the graph it is the most constant
Answer:
6
Step-by-step explanation:
I did .75 x 5 to get 75% of the road. I then converted the amount into kilometers using a reliable converter. I got 6 kilometers then.
