Each person at a picnic chose atleast one piece of a fruit one third of the people chose an apple three -quaters of the people chose a orange what fraction of the people chose both of them
Answer:
-1/12x
Step-by-step explanation:
Let total people at the picnic=x
People who chose apple= 1/3x
People who chose orange= 3/4x
People who chose each of the fruit= People who chose apple + People who chose orange
=1/3x + 3/4x
= 4x+9x / 12
=13/12x
People who chose each of the fruit= 13/12x
what fraction of the people chose both of them?
Fraction of the people who chose both fruits= Total people at the picnic - People who chose each of the fruit
=x - 13/12x
=12x- 13x /12
= -1/12 x

a basketball team won 10 games and lost 15. what is the ratio of wins to the total number of games
Answer:
The total number of games =25 which is 10+15
then the number of wins are 10.
which is 10/25.
A ratio shows us the number of times a number contains another number. The ratio of wins to the total number of games is 2/5.
What is a Ratio?A ratio expresses the number of times one number contains another. For example, if a dish of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.
Given that a basketball team won 10 games and lost 15. Therefore, the total number of games that the team plays is,
Total number of games = games won + games lost
= 10 + 15
= 25
Now, the ratio of wins to the total number of games can be written as,
Ratio = Games Won/ Total number of games
= 10/25
= 2/5
Hence, the ratio of wins to the total number of games is 2/5.

Two hikers are 88 miles apart and walking toward each other. They meet in 10 hours. Find the rate of each hiker if one hiker walls 4.4 mph faster than the other
The speed of the slow hikeris mph, and the speed of the fast hiker is mph.
(Type integers or decimals.)
Answer:
2.2 and 6.6
Step-by-step explanation:
Given:
Distance = 88 milesTime = 10 hoursRate of hiker 1 = rRate of hiker 2 = r + 4.4Then:
r + r + 4.4 = 88/102r + 4.4 = 8.82r = 4.4r = 2.2 Mph rate of hiker 1r + 4.4 = 6.6 Mph rate of hiker 2
Answer:
0.5
Step-by-step explanation:
if you do 4.4 times 10 you get 44 then you divide 44 by 88 and get 0.5
Given: If X, then Y. If Y, then Z. Y is true. So: X is unknown, Z is unknown X is unknown, Z is true X is false, Z is true X is true, Z is true
The correct option that gives a proper logic for the argument that "If X, then Y. If Y, then Z. Y is true" is given by;
Option B; X is unknown, Z is true
This question is based on the principles of logic. Logic helps us distinguish between valid and invalid arguments.Now, the argument here is that;If X, then Y. If Y, then Z. Y is true.
Now, from this argument, we can see that Y depends on X and then Z depends on Y.Now, we are told that Y is true. Since Z depends on Y as seen that If Y, then Z, we can say that Z is also true.However, we can't say anything about X as X is unknown.

Answer:
13
Step-by-step explanation:
The mean of all the numbers is the sum of the numbers divided by the number of numbers.
The sum of all of the numbers is 10 + 14 + 16 + 12 + 14 + 14 + 11 = 91.
We then divide by 7, getting 13.
Answer:
13
Step-by-step explanation:
The mean of a data set is the average value of the set.
To find the average, we simply need to add all the values and then divide by the number of values.
There are 7 values. So, add all of them and then divide by 7.
[tex]\bar x=\frac{10+14+16+12+14+14+11}{7}[/tex]
Add:
[tex]\bar x=\frac{91}{7}[/tex]
Divide:
[tex]\bar x=13[/tex]
Therefore, our average is 13.
(Note that the x with the bar on the top is a common way to denote the mean.)

The function g(x) = 3x3 + x is an odd function. Which transformations of g(x) would result in odd functions? Check all that apply. –g(x) g(2x) g(x − 1) g(x) − 3 g(–x)
Answer:
-g(x), g(2x), g(-x)
Step-by-st-ep explanation:
if f (–x) = f (x), so all of the signs are the same
you can also try on desmos, the graph is more helpful than words explain sometimes
The functions that are odd are -g(x), g(2x), and g(-x). The correct option is A, B, and E.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
For an odd function, -f(x) = f(-x).
Given that the function, g(x) = 3x³ + x is an odd function. Therefore, the transformation of the function that will again result in an odd function is,
A.) –g(x)
-g(x) = -(3x³ + x) = -3x³ - x
g(-x) = 3(-x)³ + (-1x = -3x³ - x
Thus, this is an odd function.
B.) g(2x) ⇒ Since this will result in the same function, the only difference will be that the function will be vertically stretched.
E.) g(–x)
-g(x) = -(3x³ + x) = -3x³ - x
g(-x) = 3(-x)³ + (-1x = -3x³ - x
Thus, this is an odd function.
Hence, the functions that are odd are -g(x), g(2x), and g(-x).

22. The compound inequality [tex]1-4x < 21[/tex] and [tex]5x+2 > 22[/tex] is intersection, option A is correct.
21. [tex]x+y=3^2[/tex] is not a function. Option A is correct.
22. The compound inequality [tex]1-4x < 21[/tex] and [tex]5x+2 > 22[/tex] is an example of a compound inequality involving "and."
Both inequalities need to be satisfied simultaneously for the compound inequality to be true.
Hence, the compound inequality is intersection.
21. A function is a relationship between two variables in which each input value (x) corresponds to exactly one output value (y).
In this case, the equation [tex]x+y=3^2[/tex] does not represent a clear relationship between x and y.
[tex]x+y=3^2[/tex] represents a curve in the xy-plane rather than a function.
Hence, [tex]x+y=3^2[/tex] is not a function.

d. x= -1 and y = -1
Is it perpendicular, neither, of parallel. Show work
Perpendicular.
x = -1 is a vertical line intersecting the x-axis at (-1, 0).
y = -1 is a horizontal line intersecting the y-axis at (0, -1).
Because these lines are both straight, they will eventually intersect at (-1, -1). They will also form 90° angles, the definition of perpendicular.
