In the number 3355 how many times greater is the 3 on the left than the 3 on the right
Answer:
9 times
Step-by-step explanation:
Given
[tex]Number = 3355[/tex]
Required
Determine how many times, the 3 on the left is greater than that on the right
[tex]Number = 3355[/tex]
First, we need to determine the value of the three on the left
To get its value, we have to change all other digits to 0. This gives
[tex]Left\ 3 = 3000[/tex]
Next, we need to determine the value of the three on the righy
Similarly, we have to change all other digits to 0. This gives
[tex]Right\ 3 = 0300[/tex]
[tex]Right\ 3 = 300[/tex]
Next, we calculate the positive difference between these two values and divide by the value of the Right 3
[tex]Result = \frac{Left\ 3 - Right\ 3}{Right\ 3}[/tex]
[tex]Result= \frac{3000 - 300}{300}[/tex]
[tex]Result= \frac{2700}{300}[/tex]
[tex]Result = 9[/tex]
Hence, the left 3 is 9 times greater than the right 3
Modeling Real-World Problems with Composite Functions
A retailer is having a promotional sale for 35% off all items. There is a 7% sales tax added to the price. Which
represents the situation, where x is the original cost of the item(s)?
Of(x) = 0.35x represents the diseount price and g(x) = 0.07x represents the price after taxes. The total price would
be (fog)(x) = 0.35(0.07x) = 0.0245x.
Of(x) = 0.65x represents the discount price and g(x) = 0.07x represents the price after taxes. The total price would
be (fºg)(x) = 0.65(0.07x) = 0.0455x.
Of(x) = 1.07x represents the price after taxes and g(x) = 0.65x represents the discount price. The total price would
be (fºg)(x) = 1.07(0.65x)= 0.6955x
O f(x) = 1.07x represents the price after taxes and g(x) = 0.35x represents the discount price. The total price would
be (fog)(x) = 0.35(1.07x)=0.3745x.
Answer:
The third option: (f°g)(x)=1.07(0.65x)=06955x
Step-by-step explanation:
The reason I chose this is because 0.65x is the discount price. That's because 35% off is the same as 1.00-0.35 which equals 0.65. After that you would multiply that discount price by 1.07 because you want the 7% sales tax added on to the discount price. Therefore, I would choose the third option as my answer.
Businesses in a country are listed by size: small, medium, and large. Explain why business size is an example of an ordinal-scaled variable. A. The size of a business is ordinal-scaled because it has numerical values that arise from a measuring process. B. The size of a business is ordinal-scaled because it has values that represent quantities. C. The size of a business is ordinal-scaled because it has values that can be used as an order or rank of a categorical variable. D. The size of a business is ordinal-scaled because it has numerical values that arise from a counting process.
Answer: C. The size of a business is ordinal-scaled because it has values that can be used as an order or rank of a categorical variable.
Step-by-step explanation: Ordinal variables are simply categorical in nature just like nominal variables, however, the difference exists in the fact that ordinal labels posses an ordered rank or level unlike nominal variables. Though the extent or width of the difference between these labels cannot be ascertained. In the scenario above, size of businesses are labeled qualitatively with labels such as : small, medium and large. This labels depicts and follow a certain order with small being the least, then medium, then large. Telling us large businesses are superior in size to small and medium and medium is superior to large. Though the extent of the difference cannot be accurately ascertained.
the remains of an ancient ball court include a rectangular playing alley with a perimeter of about 64 M. the length of the alley is 2 times the width. find the length and the width of the playing alley
Answer:
[tex]Length = \frac{64}{3}m[/tex]
[tex]Width= \frac{32}{3}m[/tex]
Step-by-step explanation:
Given
[tex]Perimeter = 64m[/tex]
[tex]Length = 2 * Width[/tex]
Required
Determine the length and the width
Since the alley is rectangular, the perimeter is as follows;
[tex]Perimeter = 2 (Length * Width)[/tex]
Substitute 64m for Perimeter
[tex]64m = 2(Length + Width)[/tex]
Substitute 2 * Width for Length
[tex]64m = 2(Width+ 2 * Width)[/tex]
[tex]64m = 2(Width+ 2 Width)[/tex]
[tex]64m = 2(3 Width)[/tex]
[tex]64m = 6Width[/tex]
Divide both sides by 6
[tex]Width= \frac{64m}{6}[/tex]
[tex]Width= \frac{32}{3}m[/tex]
Recall that
[tex]Length = 2 * Width[/tex]
[tex]Length = 2 * \frac{32}{3}m[/tex]
[tex]Length = \frac{64}{3}m[/tex]

Answer:
Twelve tickets cost $30 --> True
Thirty tickets cost $12 --> False
Each additional costs $2.50 --> True
The table is a partial rep --> True
ordered pairs --> False
Step-by-step explanation:
Twelve tickets cost $30 --> True, you can literally see that in the table
Thirty tickets cost $12 --> False, 30 is not in the table so you don't have that information. Besides, $12 is an unlikely low value for so many tickets.
Each additional costs $2.50 --> True, you can see the difference in the TotalCost column to be consistently 2.50.
The table is a partial rep --> True, values below 11 are not shown for example.
ordered pairs --> False --> Then the x value should be first, e.g., (11, 27.50), since the cost y is a function of the number x.
the product of x and the sum of 6 and 8 times the square of x
Answer:
x(6 + 8x²) or 6x + 8x³.
Step-by-step explanation:
"The square of x" can be represented by x² and 8 times that would be 8 * x² or 8x². The sum of 6 and 8x² can be represented by 6 + x² and the product of x and 6 + x² can be represented by x * (6 + 8x²) or x(6 + 8x²) which simplifies to 6x + 8x³.
Answer:
14x * x^2
Step-by-step explanation:
So you just have to read very carefully on these questions.
the product of x and the sum of 6 and 8
x times 6+8= x times 14= 14x
Product= multiply
Sum= add
that answer times the square of x
x^2
=14x times x^2

Which statement is true?
A. This scatter plot has no clusters and no outliers.
B. This scatter plot has one cluster and no outliers.
C. This scatter plot has one cluster and three outliers.
D. This scatter plot has one cluster and one outlier.
A cluster is a small group of dots close together. An outlier is a single dot far away from the rest of the dots.
The above graph has a small cluster around y 6&7 and has an outlier at (9,5)
The answer should be D.
Answer:
The correct answer is D. This scatter plot has one cluster and one outlier.
Step-by-step explanation:
From looking at the scatterplot, the majority of the points are collected on the upper left side of the coordinate grid, creating a cluster. This just means that these data points are located close to one another.
If we continue to look at the scatterplot, we can see that there is one data point at approximately (9, 5.25) that is very far from the other data points. This point is considered to be an outlier because it does not follow the general trend of the other data points and changes the data analysis significantly if included in the calculations.

PLEASE HELP !!! The height of a rectangle is twice the width and the area is 32. Find the dimensions.
Answer:
The rectangle has a width of 4 and a height of 8
Step-by-step explanation:
Let the height of the rectangle be H and the width be W.
We know the height of the rectangle is twice the width, so:
H = 2W
The area of a rectangle, A, is given by A = W * H, so in this case:
32 = W * 2W
32 = 2W²
W² = 16
W = 4
Knowing that the width is 4, the height must be 8. This gives us an area of 32.

what is formula for circumfrences
The circumference of a circle, which is another way of saying the perimeter of a circle, can be found using the formula 2πr.
Note that π represents the irrational number 3.14159... which
rounds to 3.14 and r represents the radius of the circle.
Therefore, since π = 3.14, another way of writing the formula
for the circumference of a circle is 2 · 3.14r or 6.28r.
Answer:
circumference = 2 π r
or
circumference = π d
Step-by-step explanation:
r = radius of a circle
d = diameter
therefore
circumference = 2 π r
or
circumference = π d

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 404 gram setting. It is believed that the machine is underfilling the bags. A 27 bag sample had a mean of 402 grams with a variance of 676. A level of significance of 0.1 will be used. Assume the population distribution is approximately normal. Is there sufficient evidence to support the claim that the bags are underfilled?
Answer:
There is no sufficient evidence to support the claim that the bags are underfilled
Step-by-step explanation:
We are given;
n = 27 bags
Sample mean;X = 402 gram
Population mean;μ = 404 gram
Variance = 676
We know that, standard deviation(σ) = √variance
Thus;
σ = √676
σ = 26
The hypotheses are;
Null hypothesis; H0: μ = 404
Alternative hypothesis; HA: μ < 404
Let's find the z-score from the formula;
z = (X - μ)/(√σ/n)
z = (402 - 404)/√(26/27)
z = -2.04
From the z-distribution table attached, we have a p-value of 0.02068
This is less than the significance value of 0.01 and thus we will reject the null hypothesis and conclude that there is no sufficient evidence to support the claim that the bags are underfilled

A random sample of 1700 workers in a particular city found 578 workers who had full health insurance coverage. Find a 95% confidence interval for the true percent of workers in this city who have full health insurance coverage.
Answer: (31.75%, 36.25%)
Step-by-step explanation:
Let p be the proportion of workers in this city who have full health insurance coverage.
As per given,
Sample size : n= 170
Number of workers who had full health insurance coverage.=578
i.e. sample proportion: [tex]\hat{p}=\dfrac{578}{1700}\approx0.34[/tex]
Also, z-score for 95% confidence level : 1.96
Formula to find the confidence interval for p :
[tex]\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]
[tex]0.34\pm (1.96)\sqrt{\dfrac{0.34(1-0.34)}{1700}}[/tex]
[tex]=0.34\pm (1.96)\sqrt{0.000132}\\\\=0.34\pm (1.96)(0.011489125)\\\\\approx 0.34\pm0.0225\\\\=(0.34-0.0225,\ 0.34+0.0225)\\\\=(0.3175,\ 0.3625) =(31.75\%,\ 36.25\%)[/tex]
Hence, a 95% confidence interval for the true percent of workers in this city who have full health insurance coverage= (31.75%, 36.25%)

Solve each absolute value equation and match them with the correct solution.
Answer:
Step-by-step explanation:
First we must understand that absolute value of a function returns both positive and negative function.
1) Given |x-6| = 5
For the positive value of the function:
x-6 = 5
Add 6 to both sides
x-6+6 = 5+6
x = 11
For the negative function:
-(x-6) = 5
Open the parentheses
-x+6 = 5
Subtract 6 from both sides
-x+6-6 = 5-6
-x = -1
x = 1
Hence x = 1, x = 11
2 ) Given |3x-7| = 12
For the positive value of the function:
3x-7 = 12
Add 7 to both sides
3x-7+7 = 12+7
3x = 19
x = 19/3
For the negative function:
-(3x-7) = 12
Open the parentheses
-3x+7 = 12
Subtract 7 from both sides
-3x+7-7 = 12-7
-3x = 5
x = -5/3
Hence x = 19/3, x = -5/3
3) Given |2x+9| - 10= 5
For the positive value of the function:
2x+9-10= 5
2x-1 = 5
Add 1 to both sides
2x-1+1 = 5+1
2x = 6
x= 3
For the negative function:
-(2x+9)-10 = 5
Open the parentheses
-2x-9-10 = 5
-2x-19 = 5
Add 19 to both sides
-2x-19+19 = 5+19
-2x= 24
x = -24/2
x= -12
Hence x = 3, x = -12
4) ) Given |5x-3|+12 = 4
For the positive value of the function:
5x-3+12= 4
5x+9 = 4
Subtract 9 from both sides
5x+9-9 = 4-9
5x = -5
x= -1
For the negative function:
-(5x-3)+12= 4
Open the parentheses
-5x+3+12 =4
-5x+15 = 4
Subtract 15 from both sides
-5x+15-15 = 4-15
-5x = -11
x = 11/5
Hence x = -1, x = 11/5
