Answer:
46
Step-by-step explanation:
turn the percentage into a fraction
so 20% is equal to 2/10.
230 is the whole number so multiply is by the numerator which is 2
230 x 2=460
and divide it by the denominator which is 10
460/10=46
32, 28, 21, 31, 18
Is 18 an outlier or no?
Answer:
No because 21 is close to it.
Step-by-step explanation:
To be considered an outlier, it would need to be a farther distance such as the distance from 28 to 21.
Hope this helps!!! PLZ MARK BRAINLIEST!!!

There's a formula for fidning out if something is an outlier or not but i forgot, pff, look it up :P
Find the arc length of major arc GH. Round your answer to the nearest tenth.
Answer:
42.1 cm
Step-by-step explanation:
The length of the arc is circumference of the circle - length of minor arc GH
circumference of circle = 2 * π * r = 2 * π * 9.1 = 18.2 π cm
The length of the minor arc = angle/360 * 2 * π * r
Now this is tricky, the angle is 360-265 = 95
The length of the minor arc = 95/360 * 2 * π * 9.1 = 4.80 π
Length of major arc = 18.2 π -4.8 π = 13.4 * π = 13.4 * 22/7 = 42.11cm

A recipe for trail mix calls for 2 3/4 cups of peanuts, 1 2/3 cups of cashews, and 1 1/6 cups of almonds.
How many cups of nuts are used in all?
Answer:
5 7/12
Step-by-step explanation:
To get the total amount of nuts used in all, what we do is to add all the fractions together
But we convert them to mixed fraction to make the work easier;
2 3/4 = 11/4
1 2/3 = 5/3
1 1/6 = 7/6
Adding all, we have;
11/4 + 5/3 + 7/6 = (33+ 20 + 14)/12 = 67/12 = 5 7/12
Answer:
4 7/12
Step-by-step explanation:
2 3/4 + (1 2/3 + 1/6) = 2 3/4 + (1 4/6 + 1/6) = 2 3/4 + 1 5/6 = 2 9/12 + 1 10/12 = 3 19/12 = 4 7/12

The table below shows the relationship between the number of miles traveled and the number of gallons of gas used. Which of the following statements best represents the relationship
A. The nu,ber of miles is the dependent quantity and the number of gallons os the dependent quantity
B. The number of miles and the number of gallons are both dependent quantities.
C. The number of gallons and the of miles are both independent quantities.
D. The number of miles is the independent quantity and the number of gallons is the independent quantity.
plz help
Answer:
Number of miles = dependent variable
Number of gallons used = independent variable
Step-by-step explanation:
In order for the driver to see how many miles the car can run, they must first see how many gallons of gas they have in the car. The number of miles depend on the number of gallons used. So, your answer would be letter choice A.
The statement which best represents the relationship is that, the number of miles is the dependent quantity and the number of gallons is the independent quantity.
What are Dependent and Independent Variables?Dependent variable are variables which depends on another variable to take it's value.
Independent variables are those which does not depend on other variables.
Given is a table which represents the number of miles travelled and the number of gallons of gas used.
From the table, if x represents the number of gallons of gas used and y represents the number of miles travelled, then the equation can be written as,
y = 35x
It is clear that, the value of y depends on the value of x.
So, x is the independent variable and y is the dependent variable.
That is, number of gallons of gas used is the independent variable and number of miles travelled is the dependent variable.
Hence the number of miles is the dependent quantity and the number of gallons is the independent quantity.

A circle has centre (0, 0) and it passes through the point (5, -3)
Find the radius of the circle, in surd form.
Answer:
radius = [tex]\sqrt{34}[/tex]
Step-by-step explanation:
The radius r is the distance from the centre to a point on the circle.
Use the distance formula to calculate r
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (5, - 3)
r = [tex]\sqrt{(5-0)^2+(- 3-0)^2}[/tex]
= [tex]\sqrt{5^2+(-3)^2}[/tex]
= [tex]\sqrt{25+9}[/tex]
= [tex]\sqrt{34}[/tex]

y = -2 - sqrt(7)
Step-by-step explanation:
y^2 +4y +4 = 7
Factor, recognizing that this is the sum of squares
a^2 +2ab+b^2 = (a+b)^2
(y+2) ^2 = 7
Take the square root of each side
sqrt((y+2) ^2) =± sqrt(7)
y+2 = ± sqrt(7)
Subtract 2 from each side
y+2-2 = -2 ± sqrt(7)
y = -2 ± sqrt(7)

The age of the volunteers at a local food bank are 34, 25, 24, 50, 18, 46, 43, 36, 32. What is the median for the data set?
It is 34
First you have to order all of the number from least to greatest:
18 24 25 32 34 36 43 46 50
Then you cross out a number from each side, until you are left with the last number, which is the median. In this case your answer is 34.

The daily low temperature in Guangzhou, China Varies over time in a periodic way that can be modeled by a trigonometric function. The period of change is exactly one year. the temperature peaks around July 26 at 78°F and has its minimum half a year later at 49°F. assuming a year is exactly 365 days July 26 is 206/365 of a year after January 1. Find the formula of the trigonometric function that models the daily low temperature T in Guangzhou t years after January 1, 2015 defined the function using radians
Answer:
T(t) = 14.5cos(2π(t -206/365)) +63.5
Step-by-step explanation:
The function can be written as ...
T = A·cos(2π(t -206/365)) +B
where A is half the difference of the high and low temperature values, and B is the average of the high and low temperature values.
A = (78-49)/2 = 29/2 = 14.5
B = (78 +49)/2 = 127/2 = 63.5
The value 206/365 is the horizontal right shift of the peak of the function. That makes the peak occur on July 26, as required.
Filling in these values gives us the function ...
T(t) = 14.5cos(2π(t -206/365)) +63.5
