Given the emoticons usage percentage, the number students at Washington Middle School who uses emoticons is approximately 2083.
Rate and PercentageRate is simply the ratio of a measure or frequency against another measure in different unit.
Percentage is a ratio expresses as a fraction of hundred.
Given the data in the question;
Percentage people who use emoticons on their instant messengers; p = 85%.Number of students at Washington Middle School n = 2450To determine the number of students Washington Middle School that use emoticons, we multiply the percentage of emoticons usage by the number of students.
N = p × n
N = 85% × 2450
N = 85/100 × 2450
N = 0.85 × 2450
N = 2082.5 ≈ 2083
Therefore, given the emoticons usage percentage, the number students at Washington Middle School who uses emoticons is approximately 2083.

Find area of shaded triangle

Step-by-step explanation:
Find the area of the figure.

3 ft

2 ft
9514 1404 393
Answer:
32 ft^2
Step-by-step explanation:
The area can be figured several ways. Here are two of them.
__
Add components
The figure can be divided into two smaller rectangles, (b) and (d) in the attached drawing. The area of each is the product of its dimensions.
Area b = (4 ft)(3 ft) = 12 ft^2
Area d = (10 ft)(2 ft) = 20 ft^2
Area of the figure is Area b + Area d = 12 ft^2 + 20 ft^2 = 32 ft^2.
__
Subtract white space
The figure is bounded by an overall rectangle that is 10 ft wide and 5 ft high. The area of that rectangle is
Area a+b+c+d = (10 ft)(5 ft) = 50 ft^2
The area of whitespace 'a' is ...
Area a = (3 ft)(3 ft) = 9 ft^2
Area c has the same dimensions, so the same area. The area of the figure is the area of the bounding rectangle less the area of the two corner white spaces (a) and (c).
Area of the figure is ...
Area a+b+c+d -Area a -Area c = 50 ft^2 -9 ft^2 -9 ft^2 = 32 ft^2.

208_32
I NEED HELP ASAP
Answer:
Step-by-step explanation:
Profit, P(x), is the difference between revenue, R(x), and cost, C(x)
R(x) = 2x^4 - 3x^3 + 2x - 1
C(x) = x^4 -x^2 + 2x + 3
Substituting into the equation
P(x) = R(x) - C(x)
= (2x^4 - 3x^3 + 2x - 1) - (x^4 -x^2 + 2x + 3)
= x^4 - 3x^3 + x^2 - 4
The answer is the lower left option.
Answer:
[tex]P(x)=x^4-3x^3+x^2-4[/tex]
(This is the option found in the lower-left corner)
Step-by-step explanation:
When given the following functions,
[tex]R(x)=2x^4-3x^3+2x-1[/tex]
[tex]C(x)=x^4-x^2+2x+3[/tex]
The problem asks one to find ([tex]P(x)[/tex]), moreover, one is given the following information,
[tex](P(x))=(R(x))-(C(x))[/tex]
Substitute,
[tex]P(x)=(2x^4-3x^3+2x-1)-(x^4-x^2+2x+3)[/tex]
Simplify, multiply everything in the second parenthesis by the negative sign outside of it,
[tex]P(x)=2x^4-3x^3+2x-1-x^4+x^2-2x-3[/tex]
Combine like terms, only operations between coefficients of the same variable with the same degree (exponent) can be performed,
[tex]P(x)=x^4-3x^3+x^2-4[/tex]
What is the mean absolute deviation of the following data: 61, 63, 64, 68, 70, 76 ROUND TO THE NEAREST HUNDREDTH Single line text.
Answer:
4.33 infinity.
Step-by-step explanation:
The infinity should just be a line over the 3's
Answer:
4.33
Step-by-step explanation:
First, find the mean value.
Mean = 67
61 - 67 = |-6| = 6
63 - 67 = |-4| = 4
64 - 67 = |-3| = 3
68 - 67 = 1
70 - 67 = 3
76 - 67 = 9
Add: 6 + 4 + 3 + 1 + 3 + 9/6 = 4.33333333333
4.33333333333 rounded to the nearest hundredth = 4.33

Answer:
D) p³ + 2; when p = 3 the number of plants is 29.
Step-by-step explanation:
Illiana cubed (³) the number of original plants, p, in the garden. Then, she added 2 more plants. We will use n for the number of total plants.
So, the equation should be p³ + 2. Substitute our value for p into the equation and solve.
p³ + 2 = n
3³ + 2 = n
27 + 2 = n
29 = n
There are 29 total plants.
The answer, then, is the last option, p³ + 2; when p = 3 the number of plants is 29.
Good luck ^^

Answer:
11 m= 3 12 slope is 4 and y intercept is 2
Step-by-step explanation:
11 slope = gradient of a line formulae y2-y1 / x2 - x1
12-6 / 4-2 =3
12 slope is the gradient so and is found as m in the equation y=mx + c
so 4 is the slope and the y intercept is where x= 0 so y = 2
