Kostya randomly chooses a number from 1 to 10. What is the probability he chooses a number less than 5?
A. 1/2
B. 4/9
C. 2/5
D. 3/5
Answer:
Step-by-step explanation:
2/5
If Kostya randomly chooses a number from 1 to 10 then 2/5 is the probability Kostya chooses a number less than 5.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given that Kostya randomly chooses a number from 1 to 10.
We have to find the probability he chooses a number less than 5
There are four numbers that are less than 5 .
The numbers less than 5 are 1, 2, 3, 4.
The probability that Kostya randomly chooses one of these numbers is 4/10,
Divide numerator and denominator by 2
We get 2/5
Hence, if Kostya randomly chooses a number from 1 to 10 then 2/5 is the probability he chooses a number less than 5.

A swimming pool is 22 feet long and 18 feet wide. How many feet of fencing are needed to enclose the pool
Answer:
80 feet
Step-by-step explanation:
length of pool = 22 , width of pool = 18
feet required for fencing the pool = 2 (l +b)
= 2 ( 22+18)
=2*40
=80feet
Answer:
Step-by-step explanation:
The pool is a rectangle as length and breadth are different.
Since they are asking about fencing you need to find the perimeter.
Length=22feet
Breadth=18feet
Perimeter of a rectangle = 2(l+b)
= 2 × 22 + 2×18
=44+36
=80 feet

Which function is the inverse of function f?
f(x)=9x^2–12
Answer: D
Step-by-step explanation:
If the equation is f(x) = 9x^2 -12, you can solve for the inverse by switching the x and y like this.
x = 9y^2-12.
Then you solve for y.
x = 9y^2-12.
x+12=9y^2
y^2=(x+12)/9
y=sqrt((x+12)/9)
y=sqrt((x+12))/3 which is D

Can someone help me find the slope , y-intercept ,and equation pls help it’s my finals
Answer:
slope: -3
y-intercept: -5
equation: y = -3x - 5
Step-by-step explanation:
The formula for slope is:
(y2 - y1)/(x2 - x1)
Let's use these coordinates:
(-1, -2)
(0, -5)
x1 = -1
x2 = 0
y1 = -2
y2 = -5
Substitute into the formula:
(y2 - y1)/(x2 - x1)
(-5 + 2)/(0 + 1)
Solve:
(-5 + 2)/(0 + 1)
-3/1
= -3
slope = -3
The y-intercept is when the x coordinate is 0.
Looking at the table, we see the coordinate (0, -5).
The y-coordinate is -5.
This means that the y-intercept is -5
y-intercept = -5
Slope-intercept form:
y = mx + b
where m is the slope and b is the y-intercept
m = -3
b = -5
Substitute:
y = mx + b
y = -3x - 5
what is the slope of the line that contains the points (-2,8) and (-2,1)
Answer:
0
Step-by-step explanation:
because -2 does not change
Answer:
Undefined
Step-by-step explanation:
To find the slope, you need the formula, y₂-y₁ divided by x₂-x₁.
That is 1-8 divided by -2-(-2), or -7 divided by 0.
Anything divided by 0 is undefined, so the answer is undefined.

Solve for I.
V = IR
What is I equal to?
Answer:
I=V/R
Step-by-step explanation:
In this equation, we see that there are no numerical values so we can't exactly solve for the exact number. Because of this, all you do Is isolate the variable "I" by itself. To do this, divide R on both sides. This way, you isolate I and on the other side you get V/R that cannot be further simplified.
Answer:
I=V/R
Step-by-step explanation:
V=IR
Divide both sides by R to isolate I
V/R=I

Find the diagonale of the base.
Answer: 8.94
Step-by-step explanation:
By common logic, you can say that l=8, w=4 and h=2.
The diagonal of the base can be found by using Pythagorean Theorem.
Pythagorean Theorem: a²+b²=c²
Since we know the a and b of the base, we can find c, the diagonal.
a and b is the l and w. We can use the equation to find c.
8²+4²=c²
64+16=c²
80=c²
c=√80
c≈8.94
The diagonal is approximately 8.94

What does the number line above represent?
Answer:
x ≤5
Step-by-step explanation:
There is a closed circle at 5 so that means equals
The line goes to the left so that means less than
x ≤5
Answer:
C
Step-by-step explanation:
Since the circle is close, we can assume it has to be C or D. But if we want to find out, we think of x as let's say 4. 4 is less than 5, and numbers 5 or less is x, so the answer would be C. (hope it helps)

What is the slope of a line that is perpendicular to the line whose equation is 2y = 3x - 1? -3 - -
Answer: 2/3x
Step-by-step explanation:
First, you need to simplify your original line to point slope formula. Dividing the whole thing by 2 to get y by itself leaves you with
y = 3/2x - 1/2
Any perpendicular line has the opposite slope to the line it is perpendicular to, so you flip the slope to get 2/3x
What is the equation of the line that passes through (0, 3) and (7,0)?
y-ix-3
3
y=x+3
3
y y=-7x+3
y=-x-3
Answer:
The equation of the line in slope-intercept form is:
[tex]y=-\frac{3}{7} x+3\\[/tex]
In one of the many possible standard forms:
[tex]3\,x+7\,y=21[/tex]
Step-by-step explanation:
First calculate the slope of the segment that joins these two points: (0, 3) and (7,0):
[tex]slope=\frac{y_2-y_1}{x_2-x_1}= \frac{0-3}{7-0}=-\frac{3}{7}[/tex]
Now, knowing that the y-intercept is (0, 3) [point on the y-axis (for x=0) where the line crosses], Then the equation of the line in slope-intercept form is:
[tex]y=m\,x+b\\y=-\frac{3}{7} x+3[/tex]
And now, if you want to write the equation eliminating fractions, we can multiply both sides by "7":
[tex]y=-\frac{3}{7} x+3\\7\,y=-3\,x+21\\3\,x+7\,y=21[/tex]

Answer:
Step-by-step explanation:
A) Cost of canvas = $ x
Cost of 4 canvases = 4 *x = 4x
Money left over after buying 4 canvases = $2.20
Equation: 25 - 4x = 2.2
Solution: Subtract 25 from both sides
-4x = 2.2 - 25
-4x = - 22.8
Divide both sides by (-4)
-4x/-4 = -22.8/-4
x = 5.7
B) Money in Molly's account= x
4 times of Molly's account = 4x
Equation: 4x - 2.2 = 25
Solution: 4x = 25 +2.2
4x = 27.2
x = 27.2/4
x = 6.8
