Answer:
Step-by-step explanation:
The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube.
6a2
Putting value of a in the equation
6(2/3)^2
= 2.6666666666666666666666
Answer:
2 2/3 square inches
Step-by-step explanation:
Since each side equals 2/3 of, say, an inch, you need to multiply 2/3 by 2/3 to get the area of one side, then multiply that value by 6 to get the total surface area.
[tex]\frac{2}{3}*\frac{2}{3}=\frac{4}{9}[/tex]
[tex]\frac{4}{9} = 0.444444...[/tex]
Now, for the total:
[tex]\frac{4}{9} * 6 = \frac{24}{9}[/tex]
[tex]\frac{24}{9} = 2\frac{6}{9}[/tex]
[tex]2\frac{6}{9} = 2\frac{2}{3}[/tex]

Find the measure of the arc or angle indicated.
Answer:
C
Step-by-step explanation:
Let solve for x
[tex]110 + 16x - 6 + 12x + 4[/tex]
[tex]28x + 108 = 360[/tex]
[tex]28x = 252[/tex]
[tex]x = 9[/tex]
Angle F is a inscribed angle that is intercepted by arc HG so
Angle F is half of Arc HG
Arc HG=
[tex]16(9) - 6 = 138[/tex]
so Angle F is
[tex] \frac{138}{2} = 69[/tex]

Answer:
x = 40
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
126° is an exterior angle of the triangle, then
x + 2x + 6 = 126
3x + 6 = 126 ( subtract 6 from both sides )
3x = 120 ( divide both sides by 3 )
x = 40

According to a survey of workers, 5/25 of them walk to work, 1/25 bike, 4/25 carpool, and 15/25 drive alone. What percent of workers walk or bike to work?
Answer: 24%
Step-by-step explanation:
First add up the proportion of people who walk to work and those who bike as well. This will show the proportion of people who walk or bike to work.
This is:
= 5/25 + 1/25
= 6/25
Then convert this to a percentage:
= 6/25 * 100
= 24%

A rectangle’s width is one-fourth of its length. Its area is 9 square units. The equation l(l) = 9 can be used to find l, the length of the rectangle.
What is the length of the rectangle?
0.75 units
1.5 units
3 units
6 units
Answer:
6 units
Step-by-step explanation:
The formula for the area of a rectangle = Length × Width
A rectangle’s width is one-fourth of its length.
W = 1/4 × L
W = L/4
Cross Multiply
L = 4W
A = 9 square units
Hence
9 = L × W
We substitute 4W for L
9 = 4W × W
9 = 4W²
We square root both side
√9 = √4W²
3 = 2W
W = 3/2
W = 1 1/2 unit or 1.5 units
Solving for L = Length
9 = L × W
9 = L × 1.5
L = 9/1.5
L = 6 units
Therefore, the Length of the rectangle = 6 units

A study was commissioned to find the mean weight of the residents in a certain town. The study examined a random sample of 132 residents and found the mean weight to be 162 pounds with a standard deviation of 35 pounds. At the 95% confidence level, find the margin of error for the mean, rounding to the nearest tenth
Answer: 6.1
We are 95% confident that the true mean weight of the population is within 6.1 pounds of the sample mean 162.
At the 95% confidence interval, the margin of error for the mean is 6.1 pounds
What is margin error?The margin of error is "a statistic expressing the amount of random sampling error in the results of a survey".
According to the question,
Number of random samples (n) = 132 residents
Mean of weight of random samples (x⁻)= 162
Standard deviation of random samples (σ)= 35 pounds
In order to find at the 95% confidence interval, the margin of error for the mean.
Margin error = z (σ/√n)
The critical region 95% confidence interval under normal curve is 1.96.
= 1.96 (35/√132)
=1.96(35/11.48)
=1.96(3.0488)
= 5.9708636 ≈ 6.1 pounds
Hence, at the 95% confidence interval, the margin of error for the mean is 6.1 pounds.

Answer:
1. 4 2. 2 3. Does not exist 4. Does not exist 5. 3
Step-by-step explanation:
1. This is the limit as x approaches 2 from the left. That means that x "sneaks up" on 2, but from the left (ironically moving right). As x does that, the graph rises, heading for 4 (even though the point is "empty"). The limit is 4. See attached image 1
2. Let x sneak up on 2 from the right (so moving left towards 2). As x does that, the graph falls, heading for the y-value 2. The limit is 2. See image 2.
3. This limit (two-sided) does not exist because the one-sided limits had different values.
4. This limit does not exist, either. The limit as x approaches 0 from the left is 4. The limit as x approaches 0 from the right is 0. These are different, so the two-sided limit is not defined.
5. g(2) = 3, where the solid dot is. It's the value of the function at x=2.
