An artist has completed 1/4 of paintings in 2 weeks. At what rate is she working?
Answers
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.

Which expression is NOT equivalent
to 1.24 X 0.9?

(124 X 9) * (100 x 10)
(0.124 X 9) X (10 x
(10 x 10)
(124 x 9) * (10 x 10)
Answers
The expression (124 × 9) × (1/10 × 1/10) is NOT equivalent to 1.24 × 0.9. which is the correct answer would be an option (D).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
A. (124 × 90) × (1/100 × 1/100) simplifies to 1.24 × 0.9 because 124 × 90 = 11160 and 1/100 × 1/100 = 1/10000, so the expression is equivalent to (11160/10000) × 0.9 = 1.24 × 0.9.
Similarly, expressions B and C can be rearranged as (9 × 1/10) × (0.124 × 10), which is also equivalent to 1.24 × 0.9.
B. (124 × 9) × (1/100 × 1/10) simplifies to 1.24 × 0.9 because 124 × 9 = 1116 and 1/100 × 1/10 = 1/1000, so the expression is equivalent to (1116/1000) × 0.9 = 1.24 × 0.9.
C. (0.124 × 9) × (10 × 1/10) also simplifies to 1.24 × 0.9 because 0.124 × 9 = 1.116 and 10 × 1/10 = 1, so the expression is equivalent to (1.116/1) × 0.9 = 1.24 × 0.9.
However, expression D cannot be rearranged to the form 1.24 × 0.9 because it contains the factors 124 and 90, which are not equivalent to 1.24 and 0.9, respectively.
Therefore, expression D is not equivalent to 1.24 × 0.9.

The average size of single-family homes in the U.S. is 2,390 square feet. A random sample of 100 homes in California yielded the mean of 2,507 square feet and the standard deviation of 257 square feet. Do the sample data provide sufficient evidence to conclude that the mean size of California homes exceeds the national average? Test using significance level of 0.01. (7 Points)
Answers
Answer:
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to conclude that the mean size of California homes exceeds the national average
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 2390 \ ft^2[/tex]
The sample size is n = 100
The sample mean is [tex]\= x = 2 507 \ ft^2[/tex]
The standard deviation is [tex]s = 257 \ ft^2[/tex]
The level of significance is [tex]\alpha = 0.01[/tex]
The null hypothesis is [tex]H_o : \mu = 2390[/tex]
The alternative hypothesis is [tex]H_a : \mu > 2390[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{ \= x - \mu }{ \frac{s}{ \sqrt{n} } }[/tex]
=> [tex]z = \frac{2507 - 2390 }{ \frac{ 257 }{ \sqrt{100 } } }[/tex]
=> [tex]z = 4.55[/tex]
From the z table the area under the normal curve to the left corresponding to 4.55 is
[tex]p-value = P( X > 4.55 ) = 0.00[/tex]
From the value obtained we see that [tex]p-value < \alpha[/tex] hence
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to conclude that the mean size of California homes exceeds the national average
In a bag, the ratio of red beads to blue beads is 3∶ 5. Beads are added to the bag, but the ratio of red beads to blue beads remains the same.
Answers
Then solve for the unknown then add the unknown to the known for the sum
In this question, we use the ratio given to complete the table.
Doing this, the completed table is:
3 - 5 - 8
6 - 10 - 16
9 - 15 - 24
12 - 20 - 32
60 - 100 - 160
75 - 125 - 200
In a bag, the ratio of red beads to blue beads is 3∶5.
This means, that for each 3 beads, there are 5 blue beads, and for each 8 beads, there are 3 red and 5 blue.
Third line:
15 blue, the amount of red is 3/5 of this, so:
[tex]\frac{3}{5}(15) = 3(3) = 9[/tex]
Thus, there are 9 red, 9 + 15 = 24, and thus, the third line is:
9 - 15 - 24
Fourth line:
32, 3/8 are red and 5/8 are blue, so:
[tex]\frac{3}{8}(32) = 3(4) = 12[/tex]
[tex]\frac{5}{8}(32) = 5(4) = 20[/tex]
Thus, the fourth line is:
12 - 20 - 32
Fifth line:
100 blue, the amount of red is 3/5 of this, so:
[tex]\frac{3}{5}(100) = 3(20) = 60[/tex]
60 + 100 = 160
Thus, the fifth line is:
60 - 100 - 160
Sixth line:
75 red, the amount of blue is 5/3 of this, so:
[tex]\frac{5}{3}(75) = 5(25) = 125[/tex]
75 + 125 = 200.
Thus, the sixth line is:
75 - 125 - 200
The complete table is:
3 - 5 - 8
6 - 10 - 16
9 - 15 - 24
12 - 20 - 32
60 - 100 - 160
75 - 125 - 200

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
Answers
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
