An artist has completed 1/4 of paintings in 2 weeks. At what rate is she working?
Answer: the rate is (1/8) paintings per week
Step-by-step explanation:
We usually define the rate as the amount of work done in some unit of time.
In this case, we know that the artist does 1/4 of a painting in 2 weeks, then the rate can be written as:
(1/4)/2 paintings/week = (1/8) paintings/week.
This means that the rate is (1/8) paintings per week, this is the weekly rate at which she works.

5. Viruses spread at an exponential rate. Write a model for a virus that starts with 1 person and increases by 400% every week. Write an exponential model in the form y=ab^x to represent this situation.
Answer:
y = 4^xStep-by-step explanation:
Initial number is 1 so a = 1
Weekly growth rate is 400% which is 4 times increase, therefore b = 4
So the function becomes:
y = 4^xsolve each inequality below using the Addition principle. Draw a graph of each solution set.
X-7 greater than O
Answer:
x > 7
Step-by-step explanation:
Given
x - 7 greater than 0
Required
Solve as inequality and represent as a graph
greater than is represented with >
So, the equation is:
x - 7 > 0
Add 7 to both sides
x - 7 + 7 > 0 + 7
x > 0 + 7
x > 7
Next, the inequality is represented on a graph.

Answer:
y = -1/3x + 3 2/3
Step-by-step explanation:
step 1. find the slope of the given line
y2-y1/x2-x1 2 - 4/ 3 + 3 = - 1 / 3
take the opposite of that and there is your slope
step 2. plug in the values to the following equation using the given point:
y - y1 = m ( x - x1 ) y - 4 = - 1/3 ( x + 1 )
step 3. solve for y
y-4 = -1/3(x+1)
-1/3(x) and -1/3(1) ----> y-4 = -1/3x-1/3
y-4+4 = -1/3x-1/3+4 ----> y = -1/3x + 3 2/3

Explanation:
Usha thinks that the area of the development will be greater than the total area of 50 football pitches.
Usha knows
• a football pitch is rectangular 100m by 50m
• 1 mile = 1600m.
Answer:
Usha is correct
Step-by-step explanation:
See attachment
Given
Dimension of the development
[tex]Height = \frac{1}{2}\ mile[/tex]
[tex]Base = \frac{1}{2}\ mile[/tex]
Dimension of a football field
[tex]Length = 100m[/tex]
[tex]Width = 50m[/tex]
First, we calculate the area of the development.
Because it is triangular in shape, the area is:
[tex]Area = \frac{1}{2} * Height * Base[/tex]
[tex]Area = \frac{1}{2} * \frac{1}{2}mile * \frac{1}{2}mile[/tex]
Convert mile to meter
[tex]Area = \frac{1}{2} * \frac{1}{2}* 1600m * \frac{1}{2} * 1600m[/tex]
[tex]Area = \frac{1}{2} * 800m * 800m[/tex]
[tex]Area = 400m * 800m[/tex]
[tex]Area = 320000m^2[/tex]
The area of 50 football pitch is then calculated as:
[tex]Area = 50 * Length * Width[/tex]
[tex]Area = 50 * 100m * 50m[/tex]
[tex]Area = 250000m^2[/tex]
By comparison:
[tex]320000 > 250000[/tex]
Hence, Usha's thought is correct

Assume that when adults with smartphones are randomly​ selected, 63​% use them in meetings or classes. If adult smartphone users are randomly​ selected, find the probability that exactly of them use their smartphones in meetings or classes.
Answer:
Solved using binomial, probability = 5.7%
Step-by-step explanation:
Number of people (N) = 7
Probability of success (using phone) = 63% = 0.63
So, probability of failure (not using phone) = 1 - 0.63 = 37
Number of success (r) = 2
N c r . P^r . Q^n-r
7 c 2 (0.63)^2 (0.37)^5
= 21 (0.3969) (0.0069)
= 0.057
A cereal manufacture has a machine that files the boxes. Boxes are labeled as 16 ounces, which is the target fill (x). The lawyers want to fill the boxes more to avoid lawsuits regarding under filling and the company president vetoes that plan, saying the company should be giving away less free cereal, not more. Her goal is to set the machine no higher than 16.2 ounces and have only 4% underweight boxes. The only way to accomplish this is to reduce the standard deviation. What standard deviation must the company achieve
Answer:
σ = 0,11
Step-by-step explanation:
We assume the boxes filling process follows a Normal Distribution, then
z(score) = ( X - μ ) /σ or z(score) = ( μ - X ) /σ
depending of the tail of the curve ( as we are evaluating boxes below mean we need to use the second equation )
where μ and σ are the mean and the standard deviation of the population
As the goal is to have boxes with no higher than 16,2 ou and only 4% of underweight boxes
4% is 0,04 that should be the area under the bell shape curve then from z table we find z(s)
z(s) = - 1,75
z(s) = ( μ - X )/σ
- 1,75 = ( 16,2 - 16 ) / σ
σ = 0,2 / 1,75
σ = 0,11
