69
Based on the table, what is the probability that a student who bought juice chosen at random purchased the grape flavor
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.

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 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]

[tex]comp_ab=\left(\dfrac{-5}{7}\right)[/tex]
[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{9+36+4}[/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
[tex]Proj_ab=\left(\dfrac{\vec{a}\cdot \vec{b}}{|\vec{a}|}\right)\left(\dfrac{\vec{a}}{|\vec {a}|}\right)[/tex]
[tex]Proj_ab=\left(\dfrac{-5}{7}\right)\left(\dfrac{<-3,-6,2>}{7}\right)[/tex]
[tex]Proj_ab=\left<\dfrac{15}{49},\dfrac{30}{49},\dfrac{-10}{49}\right>[/tex]
Therefore, scale and vector projections of b onto a are [tex]comp_ab=\left(\dfrac{-5}{7}\right)[/tex] and [tex]Proj_ab=\left<\dfrac{15}{49},\dfrac{30}{49},\dfrac{-10}{49}\right>[/tex] receptively.

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.

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:

To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (-7,1)
and slope/m=3

Simplify the expression : (3/2) of (4/7) multiplied by [(10x3)-(8x2)]
Answer: 68/7
Step-by-step explanation:
given data:
(3/2) of (4/7) multiplied by [(10x3)-(8x2)]
first we break it down into smaller sets.
= ( 3/2 ) * (4/7 )
= 6/7 * [(10x3)-(8x2)]
we open the brackets
= 6/7 * (10x3)-(8x2)
= 6/7 * 30 –16
= 6*30/7 –16
= 180/7 – 16
= 68/7

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.

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.
