Answer:
The solution set is {x : x ∈ R, x > 3} ⇒ C
Step-by-step explanation:
The solution set of the inequality x > a is {x : x ∈ R, x > a}The solution set of the inequality x < a is {x : x ∈ R, x < a}The solution set of the inequality x ≥ a is {x : x ∈ R, x ≥ a}The solution set of the inequality x ≤ a is {x : x ∈ R, x ≤ a}Let us solve the question
∵ x - 5 > -2
→ Add 5 to both sides of the inequality
∴ x - 5 + 5 > -2 + 5
∴ x > 3
→ By using the first rule above
∴ The solution set is {x : x ∈ R, x > 3}

Step-by-step explanation:
The perimeter of a rectangle is 30 cm and its length is x cm. Find its area in terms of x. step by step explanation.
Answer:
The area of the rectangle in terms of 'x' = 13x
Step-by-step explanation:
Perimeter = 30 cmLength = x cmUsing the perimeter formula to find the width w.
[tex]P=2(l+w)[/tex]
[tex]P = 2l + 2w[/tex]
[tex]2w = P-2l[/tex]
Dividing both sides by 2
[tex]w\:=\:\frac{P}{2}-2[/tex]
as P = 30 cm
[tex]w\:=\:\frac{30}{2}-2[/tex]
[tex]w\:=\:15-2[/tex]
[tex]w = 13[/tex] cm
Using the formula of the rectangle area
[tex]A = wl[/tex]
substitute w = 13 and l = x in the formula
[tex]A=13\times \:x[/tex]
[tex]A = 13x[/tex]
Therefore, the area of the rectangle in terms of 'x' = 13x
"A number x increased by 6, and then doubled."

2x + 6
B
B)
2x - 6
2(x + 6)
D)
246 - x)
Answer:
(X + 6 ) ×2
It is given in the question that the no. is increased by 6 so if we take the no. as X the new no. formed is X + 6 now on doubling it the answer we get is. 2(X+6)
The correct algebraic expression is option C) 2(x + 6) matches the expression that represents the number x increased by 6, and then doubled.
Given that : "a number x increased by 6, and then doubled," perform the operations in the correct order.
To represent the given scenario of "a number x increased by 6, and then doubled," required to follow the steps:
Step 1:
Let the number be x.
Increase the number x by 6:
x + 6.
Step 2 :
Double the result by multiply the expression:
(x + 6)2,
Remove brackets by BODMASS gives:
2* x + 2 *6
On multiplying gives:
2x+12
ON taking common factors 2 gives:
2(x+6)
Therefore, the correct expression is 2(x + 6).
Option C) 2(x + 6) matches the expression that represents the number x increased by 6, and then doubled.

What is the probability that a data value in a normal distribution is between a
z-score of -1.32 and a z score of 1.32? Round your answer to the nearest
tenth of a percent.
A. 84.3%
B. 82.3%
C. 83.3%
D. 81.3%
Please tell me how to do this in my calculator
Answer:
The probability that a data value in a normal distribution is between a
z-score of -1.32 and a z score of 1.32 is 81.3%
Option D is correct.
Step-by-step explanation:
We need to find the probability that a data value in a normal distribution is between a z-score of -1.32 and a z score of 1.32.
We can write it as P(-1.32 < Z < 1.32)
It is equal to : [tex]P(-1.32 < Z < 1.32)= P(Z<1.32)-P(Z<(-1.32))[/tex]
Looking at z-score tables to find value of z=1.32 and z=-1.32
P(Z<1.32)= 0.90658
P(Z<-1.32) = 0.09342
Putting values and finding answer
[tex]P(-1.32 < Z < 1.32)= P(Z<1.32)-P(Z<(-1.32))\\ P(-1.32 < Z < 1.32)=0.90658-0.09342\\P(-1.32 < Z < 1.32)=0.81316\\P(-1.32 < Z < 1.32)=81.3\%[/tex]
So, the probability that a data value in a normal distribution is between a
z-score of -1.32 and a z score of 1.32 is 81.3%
Option D is correct.

Time
What is the speed (in miles per hour) of the train?
Answer:
50 miles per hour
Step-by-step explanation:
The speed can be found from a graph of distance versus time by looking at the slope of the graph. Here, the graph is a straight line, so the slope is constant. This means the speed is constant.
__
It can be convenient to determine the speed by looking at distance for times that are 1 time unit apart. Here, that could be the distances at t=0 and at t=1. We see in that hour, the train traveled from 100 miles to 150 miles away from the station. Its speed was 150 -100 = 50 miles per hour.
Answer:
50 miles per hour

how do I Translate the following verbal statement into an algebraic equation and then solve: Krystal bought a nightstand on sale for $170, which was one-fourth of the original price. What was the original price of the nightstand
Answer:the original price is $680
Step-by-step explanation:
1/4(x)=170
4×1/4(x)=4×170
x=$680
The original price of the nightstand is $680.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Krystal bought a nightstand on sale for $170, which was one-fourth of the original price.
Let the original price of nightstand be x.
Now, 1/4x =170
x=170×4
x=$680

What’s the slope of the line containing the two points
Answer:
The slope is 3/2 or 1.5
Step-by-step explanation:
To find the slope, simply divide the rise by the run. The rise of this line can be found by subtracting one y coordinate by another (it doesn't matter which by which). The run can be found by subtracting one x coordinate by another (it doesn't matter which by which).
So, let's say, for the y coordinates, I choose to subtract 3 by 0. 3 - 0 = 3. 3 is your rise.
For the x coordinates, I can choose to subtract -5 by -7. -5 - (-7) = 2. 2 is your run.
The slope is rise/run, so your answer is 3/2, which, in decimal form, is 1.5.
