O A. 0.2
B. 0.25
OC. 0,3
D. 0.33
Answer: A. 0.2
Step-by-step explanation:
Probability for any event = [tex]\dfrac{\text{Favorable outcomes for event}}{\text{Total possible outcomes}}[/tex]
Three flavors of juice are offered at a school cafeteria.
The given table:
Orange Grape Cherry
51 30 69
Total juices = 51+30+69 =150
Now, the probability that a student who bought juice chosen at random purchased the grape flavor= [tex]\dfrac{\text{Number of grape juices}}{\text{Total juices}}[/tex]
[tex]=\dfrac{30}{150}=0.2[/tex]
Hence, the correct option is A.

Write as many equations as possible that could represent the relationship between
the ages of the two children in each family described. Be prepared to explain what each part of your equation represents.
a.) In Family A, the youngest child is 7 years younger than the oldest, who is 18.
b.) In Family B, the middle child is 5 years older than the youngest child.
Answer:
a) Here we have:
"In Family A, the youngest child is 7 years younger than the oldest, who is 18"
Let's define:
Y = age of the youngest child.
O = age of the oldest child.
Then we know that:
Y = O - 7
O = 18
Then we can replace the second equation into the first one:
Y = 18 - 7 = 11.
b) Here we have:
"In Family B, the middle child is 5 years older than the youngest child."
Let's define:
Y = age of the youngest child.
M = age of the middle child.
Here we have only one equation:
M = Y + 5.
Answer:
your answer is....
Step-by-step explanation:M = Y + 5.

Determine whether the function is linear, exponential, or neither
Answer:
linear
Step-by-step explanation:
First differences of the y-values for the consecutive x-values are ...
-3 -(-4.5) = 1.5
-1.5 -(-3) = 1.5
0 -(-1.5) = 1.5
1.5 -0 = 1.5
The first differences are constant, so the function is linear.
__
Since we know the function is linear, there's no real point in computing the ratios of successive outputs. In any event, we know it is not constant. The ratio with 0 as a numerator will be 0; the ratio with 0 as a denominator will be undefined.
The formula=A+2lh+2wh gives surface area a. Of a rectangler solid with length, width, and height, L,W, and H, respectively solve the formula for L
Answer:
[tex]l= \frac{A}{2h} -w[/tex]
Step-by-step explanation:
The question is not correct (particularly the expression for the area)
A=2lh+2wh
Now we are expected to solve for l, that is we are going to make l subject of the formula, we have
let us take the second term on the RHS to the LHS
[tex]A-2wh= 2lh[/tex]
we can now divide both sides by 2h we have
[tex]\frac{A-2wh}{2h} = l\\\\l=\frac{A}{2h} -\frac{2wh}{2h} \\\\l= \frac{A}{2h} -w[/tex]
hence the expression for the length is [tex]l= \frac{A}{2h} -w[/tex]
A drone flies in a circular path around an object that is 100 feet east and 50 feet north of the drone operator. The drone's path takes it over a point that is 40 feet east and 30 feet south of the drone operator. Find an equation for the drone's path. Does the drone cross a north-south line through the operator's position? If so, where? If not, explain why. Suppose the drone operator is facing the object. Is the drone ever "behind" the drone operator? Why/why not?
Answer:
See below
Step-by-step explanation:
Let's plot the points for visibility
Operator position is origin (0, 0)Drone passes through points:(100, 50) and (40, -30)The path makes a line. The equation in slope-intercept form:
y = mx + bSlope:
m = (-30 - 50)/(40-100) = -80/-60 = 4/3y -intercept:
50 = 4/3*100 + bb = 50 - 400/3 = - 250/3The equation:
y = 4/3x - 250/3Questions:
Does the drone cross a north-south line through the operator's position?
No, as y-intercept is not zero. See attachedSuppose the drone operator is facing the object. Is the drone ever "behind" the drone operator?
No. See attachedHaving trouble with this one
Answer:
Yes
Step-by-step explanation:
If the diagonals are perpendicular, then the slope of AC will be the opposite reciprocal of the slope of BD.
The slope of AC is:
m = (3 − 3) / (6 − 0) = 0
The slope of BD is:
m = (0 − 6) / (3 − 3) = undefined
The opposite reciprocal of 0 is undefined, so the diagonals are indeed perpendicular.
Specifically, AC is horizontal and BD is vertical.

What is function?A function from set X to set Y is created by assigning an element from set Y to each element in set X.
The function's domain and codomain are respectively referred to as the sets X and Y and considered as a whole.
A function, its domain, and its codomain are denoted by the notation f:X→Y.
The image of x under f or the value of f applied to the input x are terms used to describe the value of a function at an element x of X, indicated by the notation f(x).
The functions can also be referred to as maps or mappings.
In this question;
Given function is f(x) = (x+1)²
We have to find the value of f(2) that means we have to put 2 in the place of x in f(x)
Thus,
⇒f(x) = (x+1)²
⇒f(2)= (2+1)²
⇒f(2)= 3²
⇒f(2) = 9
Hence, the value of f(2) if f(x) = (x+1)² is 9.

Solve for x: 2x – y = (3/4)x + 6.
(a) (y + 6)/5,
(b) 4(y + 6)/5,
(c) (y + 6),
(d) 4(y - 6)/5.
Answer:
B
Step-by-step explanation:
2x – y = (3/4)x + 6.
or, 2x - (3/4)x = y + 6.
or, (8x -3x)/4 = y + 6.
or, 5x/4 = y + 6.
or, 5x = 4(y + 6).
or, 5x = 4y + 24.
or, x = (4y + 24)/5.
Therefore, x = 4(y + 6)/5.
The area of a rectangle is 18, The number of square feet is a member of which set subsets of real numbers?
Answer:
The area of a rectangle is a natural number, an integer and a rational number.
Step-by-step explanation:
The area of a rectangle is a member of the following three subsets of real numbers:
(i) Natural numbers ([tex]\mathbb{N}[/tex]) - The area of the rectangle has no decimal parts and is positive.
(ii) Integer ([tex]\mathbb{Z}[/tex]) - The area of the rectangle has no decimal parts.
(iii) Rational numbers ([tex]\mathbb{Q}[/tex]) - The area of the rectangle can be obtained by dividing a natural number by other natural number. For instance:
[tex]\frac{36}{2} = 18[/tex]
In a nutshell, the area of a rectangle is a natural number, an integer and a rational number.

The ages of Edna, Ellie, and Elsa are consecutive integers. The sum of their ages is 120 .
Answer:
The answer is 39, 40, and 41
Step-by-step explanation:
You would use the equation x+x+1+x+2=120 to substitute for the ages. x would represent the youngest, then you would add a year to get the middle child (since it is consecutive numbers) then you would add 2 to get the oldest. And when you get the answer to the equation (which is 39) that is only the age of the youngest (since you solve only for x and that represents the youngest child's age), so you have to add 1 and 2 to the answer to get the ages of the other two.
Hope this helped :)
Edna = 39 years
Ellie = 40 years
Elsa = 41 years
Step-by-step explanation:Edna = n
Ellie = n + 1
Elsa = Ellie + 1 = (n + 1) + 1 = n + 2
Edna + Ellie + Elsa = 120
replace
n + (n + 1) + (n + 2) = 120
3n + 3 = 120
3n = 120 - 3
3n = 117
n = 117 : 3
n = 39
Edna = n = 39 years
Ellie = n + 1 = 39 + 1 = 40 years
Elsa = n + 2 = 39 + 2 = 41 years
Find the scalar and vector projections of b onto a. a = −3, −6, 2 b = 1, 1, 2

[tex]Proj_ab=\left<\dfrac{15}{49},\dfrac{30}{49},\dfrac{-10}{49}\right>[/tex].
Step-by-step explanation:
The given vectors are
[tex]\vec{a}=<-3,-6,2>,\vec{b}=<1,1,2>[/tex]
Now,
[tex]|\vec{a}|=\sqrt{(-3)^2+(-6)^2+(2)^2}[/tex]

[tex]|\vec{a}|=\sqrt{49}[/tex]
[tex]|\vec{a}|=7[/tex]
[tex]\vec{a}\cdot \vec{b}=(-3)(1)+(-6)(1)+(2)(2)[/tex]
[tex]\vec{a}\cdot \vec{b}=-3-6+4[/tex]
[tex]\vec{a}\cdot \vec{b}=-5[/tex]
The scalar projection of b onto a is
[tex]comp_ab=\left(\dfrac{\vec{a}\cdot \vec{b}}{|\vec{a}|}\right)[/tex]
[tex]comp_ab=\left(\dfrac{-5}{7}\right)[/tex]
Vector projection of b onto a is

A cheetah can run at top speed for only about 20 seconds
im pretty sure this is false they can run fro 30 seconds not 20
Answer:
A cheetah can run at top speed for only about 20 seconds. If an antelope is too far away for a cheetah to catch it in 20 seconds, the antelope is probably safe. Your friend claims an antelope running 60 feet per second will not be safe if the cheetah running at 90 feet per second is 650 feet behind it.

The model represents an equation. What value of X makes the equation true?
Answers are: -15
-3

Please help.
Answer:
D. 3
Step-by-step explanation:
Assuming the model represents an equation, the following can be deduced:
On the left side of the equation, the model shows we have 3 "x's", and 6 "1's". Let this represent:
3x + 6
On the right side of the equation, we have 2 "x's" and 9 "1's". Let this represent:
2x + 9.
The model would represent the equation below:
[tex] 3x + 6 = 2x + 9 [/tex]
Solve for x
[tex] 3x + 6 - 2x = 2x + 9 - 2x [/tex] (Subtracting 2x from both sides of the equation)
[tex] x + 6 = 9 [/tex]
[tex] x + 6 - 6 = 9 - 6 [/tex] (subtracting 6 from both sides of the equation)
[tex] x = 3 [/tex]

Solve the following inequality:
4x^2-25<0
I will give the person who answers this correctly brainiest.
Answer:
−2.5<x<2.5
Step-by-step explanation:
Let's find the critical points of the inequality.
4x2−25=0
4x2−25+25=0+25(Add 25 to both sides)
4x2=25
4x24=25/4(Divide both sides by 4)
x2=25/4
x=±√254(Take square root)
x=2.5,−2.5
Check intervals in between critical points. (Test values in the intervals to see if they work.)
x<−2.5(Doesn't work in original inequality)
−2.5<x<2.5(Works in original inequality)
x>2.5(Doesn't work in original inequality)
