Patty counted 250 chocolate chips on a tray of cookies. The actual amount of chocolate chips on the tray were 265. What is the percent error? *
Answers
Answer:
percent error=6%
Step-by-step explanation:
Step one:
given data
Patty counted 250
The actual amount of chocolate chips on the tray were 265
Required
The percent error
Step two:
The formula is
percent error= actual-expected/expected*100
percent error= 265-250/250*100
percent error=15/250*100
percent error=0.06*100
percent error=6%

The function f(x) is a cubic function and the zeros of f(x) are -5, -3 and 1. The y-intercept of f(x) is -45. Write the equation of the cubic polynomial in standard form.
Answers
Step-by-step explanation:
Since -5, -3 and 1 are the zeroes of f(x),
(x + 5), (x + 3) and (x - 1) are factors of f(x).
=> f(x) = a(x + 5)(x + 3)(x - 1),
where a is a real constant.
We are given that when x = 0, f(x) = -45.
=> a(0 + 5)(0 + 3)(0 - 1) = -45
=> -15a = -45, a = 3.
Hence, f(x) = 3(x + 5)(x + 3)(x - 1)
= 3x³ + 21x² + 21x - 45.
Answer:
The function f(x) is a cubic function and the zeros of f(x) are -5, -3 and 1. The y-intercept of f(x) is -45.
(x+5), (x+3) and (x-1) are the factors of f(x).
Form : f(x)=a(x+5)(x+3)(x-1)
When f(x)=-45 and x=0, we get a=3
Equation of the cubic polynomial in standard form is :---
[tex]f(x) = 3(x + 5)(x + 3)(x - 1)\\ =3 ( {x}^{2} + 8x + 15)(x - 1) \\=3({x}^{3} + 8 {x}^{2} + 15x - {x}^{2} - 8x - 15) \\ =3({x}^{3} + 7{x}^{2} + 7x - 15)\\=\boxed{3{x}^{3}+21{x}^{2}+21x-45}[/tex]

mark is 11 3/4 years old.marian is 1 1/2 years older than mark and jane is 1 1/5 years older than marian.how old is jane?
Answers
Jane is 19 9/20 years old. If Marian is 11/2 years bigger then Mark, you would have to add both ages up and then get the answer of 17 1/4. Then it said that Jane is 11/5 years older than Marian which means that you would have to add again to find the final answer. 11/5=2 1/5 and then add 17 1/4 which you get 19 9/20. So Jane is 19 9/20 years old.
Answer:
22/3 years old jane
Step-by-step explanation:
add 11+11 =22
2+5=7
7-3=4
so, she's 22/3 years old

What is outlier of a data?An outlier is an observation that lies an abnormal distance from other values in a random sample from a population.
Given is a dataset shown in the image.
Arrange the data in ascending order -
(6, 7, 8, 8, 9, 10, 10, 11, 12, 13, 13, 14, 15, 15, 15, 40)
(x₁, x₂, x₃, x₄, x₅, x₆, x₇, x₈, x₉, x₁₀, x₁₁, x₁₂, x₁₃, x₁₄, x₁₅, x₁₆)
First quartile -
Q{1} = (x₅ + x₄)/2 = (9 + 8)/2 = 8.5
Q{1} = 8.5
Third quartile -
Q{3} = (x₁₂ + x₁₃)/2 = (14 + 15)/2 = 14.5
Q{3} = 14.5
Interquartile range -
IQR = Q{3} - Q{1}
IQR = 14.5 - 8.5
IQR = 6
Outliers -
(numbers less than Q1 – 1.5 × IQR) = - 0.5
(numbers greater than Q3 + 1.5 × IQR) = 23.5
Therefore, the outliers of the given data seta are -
- 0.5 and 23.5

the ratio of the length to the breadth of a rectangle is 7:3. calculate the dimensions of the rectangle if the area is 525m²
Answers
Answer:
Length = 367.5 m.
Breadth = 157.5 m.
Step-by-step explanation:
The ratio is 7:3 .
There are 7 + 3 = 10 'parts' in the ratio.
So we work out the multiplier which is 525 / 10 = 52.5
Length = 7 * multiplier
= 7 * 52.5
= 367.5
Breadth = 3 * multiplier
= 3 * 52.5
= 157.5.
