Identify the variable as being discrete or continuous A person's age
Answer: A Person's age is usually considered a discrete variable.
Step-by-step explanation: lets say a person was born in November 2000 and the date is currently September 2020 if asked their age the person would say 19 because they have not turned 20 yet. therefore no matter what date anytime between their 19th birthday up until their 20th birthday they would say they are 19 making age a discrete variable.

7 + x - (3 + 32 = 8) = 3
Answer:X=3
Step-by-step explanation:We simplify the equation to the form, which is simple to understand
7+x-(3+32/8)=3
Simplifying:
7+x-(3+4)=3
Simplifying terms in parentheses
7+x-(+7)=3
Remove unnecessary parentheses
7+x-7=3
We move all terms containing x to the left and all other terms to the right.
+1x=+3-7+7
We simplify left and right side of the equation.
+1x=+3
We divide both sides of the equation by 1 to get x.
x=3
Convert 50 miles per hour to feet per second ( 1 mile = 5280 feet and 1 hour = 3600 seconds )
Answer:
73.3
Step-by-step explanation:
50mi/h * 5280ft/mi * 1h/3600s = 220/3 = 73.3 ft/s
Answer:
73 1/3 feet per second
Step-by-step explanation:
50 miles per hour
50*5280/3600 = 73 1/3 feet per second

Which value is equivalent to 0.5?
Answer:
1. 5/10
Step-by-step explanation:
Since the options are in fractions, you have to mave 0.5 into a fraction. It is 5 tenths so 5/10 which is 1/2.
The first one is 5/10
1 x 5 = 5
2x 5 =10
So this is equivalent Since there is only one answer, you don't have to try out the rest, thankfully ;)
Hopw this helps :)
Answer:
1.5/10 is the answer
Match to the answer
Answer:
square roots
quadratic formula
factoring
complete the square
Step-by-step explanation:
1. In the first one, we can divide both sides by -2 and then square root it, getting x^2 = -98 so x = 7i \sqrt(2).
2. We can use the quadratic formula to find out the second one.
3. We can factor 4x^2 - 21x - 18 = 0 and get (x + 6)(4x - 3).
4. In the last one, we can complete the square, getting (x + 9)^2 + 16.

The set of ordered pairs a where
t is the time in seconds after
someone jumps out of a plane at
4000 meters to go skydiving, and d
is the displacement above the
ground
I need to find the domain and Range.
Answer: Domain is [tex][0,\infty)[/tex] and range is [0,4000].
Step-by-step explanation:
It is given that, the set of ordered pairs (t,d), where
t = the time in seconds after someone jumps out of a plane at 4000 meters to go skydiving
d = is the displacement above the ground.
It means t is independent variable and it is represented on the x-axis.
d is dependent variable and it is represented on the y-axis.
We need to find the domain and Range.
Domain is the set of input values.
Here, input is time and time can not be negative.
Domain [tex]=0\leq t=[0,\infty)[/tex]
Range is the set of output values.
Here, output is displacement above the ground which can not be negative or more than 4000 meters.
Range [tex]=0\leq d\leq 4000=[0,4000][/tex]
Therefore, domain is [tex][0,\infty)[/tex] and range is [0,4000].

Simplify your answer as much as possible.
Answer:
Hi there!
Your answer is 15
Step-by-step explanation:
3y+17=62
Step 1 : isolate y by subtracting 17 from both sides.
3y= 62-17
3y = 45
Step 2: Divide out the 3 so you have 1y.
3y=45

Solve the inequality. 20<5/6w
Answer:
w>24
Step-by-step explanation:
Let's solve your inequality step-by-step.
20<5/6w
Answer: x>24
Step-by-step explanation:
To solve the inequality, we want to isolate w.
[tex]20<\frac{5}{6}w[/tex] [multiply both sides by 6/5]
[tex]w>24[/tex]
Now, we know that w>24 or 24<w.
