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.

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

Explanation:
solve 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.
See attachment for graph
The shaded part of the graph represents the solution to the graph.

Helpppp meeee fassttt pleaseeee
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

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
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^xFind the value of 24/25 divided by 4/5. Show your reasoning
Answer: 6/5
Step-by-step explanation:
24/25 divided by 4/5 equals 1.2 as a decimal and 6/5 as a fraction.
The simplified form of the expression is 30
Given the expression 24/25 divided by 4/5, this can also be written as:
x = 24/25 ÷ 4/5Replace the division sign with multiplication sign to have:
x = 24/25 × 5/4
x = 6 × 5
x = 30
Hence the simplified form of the expression is 30
