student is selected at random what is the probability the student is a female junior
Answer:
20%
Step-by-step explanation:
total male = 14
total female = 16
total students 30
there are only 6 females that are juniors so the probability of picking one would be 6/30
and 6/30 is equal to 0.2 (divide)
and 0.2 is equal to 20% (move the decimal right two spaces)

Find the distance from point A(2,-1) to the line y=-x+4
9514 1404 393
Answer:
(3/2)√2 ≈ 2.1213 units
Step-by-step explanation:
The distance d from point (x, y) to line ax+by+c = 0 is given by ...
d = |ax +by +c|/√(a^2 +b^2)
We can write the equation of the line as ...
x + y -4 = 0
so the distance is ...
d = |x + y - 4|/√(1^2 +1^2)
For point (x, y) = (2, -1), the distance is ...
d = |2 +(-1) -4|/√2 = 3/√2 = (3√2)/2
The distance from A(2, -1) to the line y = -x +4 is (3√2)/2 units.

Answer:
x = 40
Step-by-step explanation:
Both angles are opposites and will therefore have the same measurements.
Set your formula up as
142 = 3x + 22
142 - 22 = 3x
120 = 3x
120/3 = x
40 = x
You can also test this by placing 40 in place of x in your formula to check your work
3 * 40 + 22 = 142

I need help please I dont get this
Answer:
Step-by-step explanation:
Since this is a 30-60-90 triangle, we need the Pythagorean triple for such a triangle. the side length across from the 30 degree angle is labeled as x, the side across from the 60 degree angle is x√3, and the hypotenuse is 2x. Since we know the side length of the side across from the 60 degree angle, we use that identity and solve for x:
[tex]x\sqrt{3}=18[/tex] and
[tex]x=\frac{18}{\sqrt{3} }[/tex] and rationalizing the denominator,
[tex]x=\frac{18}{\sqrt{3} }*\frac{\sqrt{3} }{\sqrt{3} }=\frac{18\sqrt{3} }{3}=6\sqrt{3}[/tex]
This is the side length of the side across from the 30 degree angle. In order to find the hypotenuse, we have to multiply this value by 2 to get
12√3, the third choice down.
What is the greatest common factor that can be factored out of the polynomial 64x5 – 16x3 + 80x
Answer:
GCF = 16

All 3 coefficients are divisible by 16, and 16 is the greatest factor that can divisible.
Answer:
GCF = 16
Step-by-step explanation:
64/16 = 4
16/16 = 1
80/16 = 5
All of the terms in the polynomial are able to be divided by 16 the GCF.

What are all possible values of x? (This is not a right triangle!)
Answer:
solution set for x = { 4,5,6}
Answer:
2<x<12
Step-by-step explanation:
Firstly, look at this formula-
a-b<x<a+b
If we make 7, A, and 5, B, then the formula would be 7-5<x<7+5
So after you do the math it would be 2<x<12
Hence, the answer is 2<x<12
BTW if the answer is correct then can you please mark me brainlyest?
I'm only 9 years old
Thanks!
What is the solution set to the inequality 5(x - 2)(x + 4) > 0?
O {xx>-4 and x <2}
O {x| X <-4 or x > 2)
O {x} x <-2 or x > 4)
O {X/ x>-2 or x <4}
Answer:
{x | x < 2 and x < -4 }
Step-by-step explanation:
Given the inequality 5(x - 2)(x + 4) > 0?
This also means x - 2 < 0 and x + 4<0
For x - 2 < 0
Add 2 to both sides
x - 2 + 2 < 0 + 2
x < 2
Similarlry for x + 4 <0
Subtract 4 from both sides
x+4-4 < 0 -4
x < 0 -4
x < -4
x < 2 and x < -4
Hence the required solution is {x | x < 2 and x < -4 }
In a class of students, the following data table summarizes how many students passed
a test and complete the homework due the day of the test. What is the probability that
a student chosen randomly from the class did not complete the homework?
Answer:
3/16
Step-by-step explanation:
The total number of students = no. of students passed + number of students who failed.
i.e, 13+3=16
probability = 3/16 = 0.1875
Hope u understand
Please mark as the brainliest

B: h=112fandf=12h
C: f=h+12andh=f−12
D: h=f+12andf=h−12
Answer:
Can't really read that but these would work
f = 12h
h = f/12

Jenna is opening a clothing store. She plans to start by selling T-shirts. If it
costs her $7 for each shirt, $2 for ink per shirt, and $0.10 a bag, what is her
unit cost per shirt?
O A. $9.10
O B. $2.10
O c. $4.55
O D. $7.00
Her unit cost per shirt is,
= $9.10
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
Jenna's unit cost per shirt is, $9.10
Here, We have;
Cost for each shirt = $7
Cost for ink per shirt = $2
Cost of a bag = $0.10
Hence, Cost of T-shirt is,
= Cost for each shirt + Cost for ink per shirt + Cost for bag
= $7 + $2 + $0.10
= $9.10
Thus, Her unit cost per shirt is,
= $9.10

Joe can weed the garden twice as fast as his sister Janet. Together they can weed the garden in 2 hours. How long would it take each of them working alone?
A:[tex]\frac{1}{x}[/tex]
Answer:
Joe: 3 hrs
Janet: 6hrs
Step-by-step explanation:
joe takes x hours
so in 1 hr he does 1/x of the garden
janet takes 2x hours
so in 1 hr she does 1/(2x) of the garden
In one hour together they do 1/2 of the garden
1/x + 1/(2x) = 1/2
2/(2x) + 1/(2x) = 1/2
3/(2x) = 1/2
Cross multiply
6 = 2x
x = 3
Joe: 3 hrs
Janet: 6hrs
