Answer:
The surface area of the cylinder is about 954.56 square inches.
Step-by-step explanation:
The total surface area of a cylinder is given by the formula:
[tex]SA=2\pi r^2 + 2\pi rh[/tex]
Here, we are given that the radius is 8 inches and that the height is 11 inches. We are also using 3.14 for π. So, substitute:
[tex]SA\approx 2(3.14)(8)^2+2(3.14)(8)(11)[/tex]
Use a calculator:
[tex]SA\approx 954.56\text{ in}^2[/tex]
The surface area of the cylinder is about 954.56 square inches.

A bag contains 10 marbles. Four of
them are red, three blue, two white,
and one yellow. A marble is drawn at
random. What is the probability that it
is not white? Be sure to reduce.
[? ]
Answer:
4/5
Step-by-step explanation:
There are a total of 10 marbles. Out of those 10 marbles, 8 of them are NOT white. Therefore, the probability of getting a marble that is not white is 8/10 = 4/5.
The probability that a randomly drawn marble is not white is 4/5.
To find the probability that a randomly drawn marble is not white, we need to determine the number of non-white marbles and divide it by the total number of marbles.
In the given bag, there are 10 marbles in total, and 2 of them are white. Therefore, there are 10 - 2 = 8 non-white marbles.
The probability of drawing a non-white marble can be calculated as:
Probability = Number of non-white marbles / Total number of marbles
= 8 / 10
= 4 / 5
Therefore, the probability that a randomly drawn marble is not white is 4/5.

b. Allan has 5 boxes of baseballs. Each box contains 2 dozen balls. He wants to divide the balls between 6 teams. How many balls will each team receive?
Answer:
20 balls to each team
Step-by-step explanation:
If 5 boxes contains 2 dozens
And 2 dozens= 24
Multiply boxes by dozens of balls
5×24=120
Then to share, you divide it buy the number of teams
120÷6= 20 balls
A restaurant wants to study how well its salads sell. The circle graph shows the sales over the past few days. If 35 of the salads sold were Caesar salads, how many total salads did the restaurant sell?
Answer:
50
Step-by-step explanation:
From the circle graph :
Salad sold :
Caesar = 70%
Garden = 16%
Taco = 14%
If 35 of the salad sold were Caesar ;
Then ; this means
70% = 35
Total salad sold %= (70+16+14)% = 100%
Let total sales = x
70% = 35
100% = x
Cross multiply :
70% * x = 100% * 35
0.7x = 35
x = 35 / 0.7
x = 50

There were 3450 previously owned homes sold in eastern Washington in the year 2010. The distribution of the sales prices of these homes was as strongly right-skewed with a mean of $406,274 and a standard deviation of $49,981. If all possible simple random samples of size 200 are drawn from this population and the mean is computed for each of these samples which of the following describes the sampling distribution of the sample mean?
a. Right skewed with mean of $406,274 and standard deviation of $49,981.
b. Approximately normal with mean $406,274 and standard deviation$249
c. Approximately normal with mean of $406,274 and standard deviation of $49,981.
d. Right skewed with mean of $406,274 and standard deviation $3534
e. Approximately normal with mean of $406,274 and standard deviation $3534
Answer:
e. Approximately normal with mean of $406,274 and standard deviation $3534
Step-by-step explanation:
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean 'μ' and standard deviation 'σ' , the sampling distribution of the sample means with size 'n' can be approximated to a normal distribution with mean 'μ' and standard deviation s= σ / √n .Given,The distribution of the sales prices of these homes was as strongly right-skewed with a mean of $406,274 and a standard deviation of $49,981 & Sample of Size 200 Are Drawn .
Now, By the Central Limit Theorem, the approximately normal Mean is $406,274 .
And,
Standard deviation ⇒ s= σ / √n ⇒ $49981 / [tex]\sqrt{200}[/tex]
⇒ $49981 / 10×√2 ⇒ $4998.1 / √2 ⇔ $3534.72 ≈ $3534

what are the missing proof
A. Substitution; converse of diagonals theorem
B. Sum of interior angles; converse of opposite angles theorem
C. Substitution, converse of opposite angles theorem
D. Sum of interior angles; converse of diagonals theorem
I think it's between B and C
Answer:
B. Sum of interior angles; converse of opposite angles theorem
Step-by-step explanation:
In statement 1, all the interior angles of the quadrilateral are added to give a sum of 360°. The reason would therefore be "sum of interior angles".
As a follow up to the already established fact that the opposite angles of the quadrilateral are congruent to each other, this satisfies the Converse of Opposite Angles Theorem, which states that if the opposite angles of a quadrilateral are congruent to each other then the quadrilateral must be a parallelogram.
Reason for the statement in number 6 is definitely "converse of opposite angles theorem."
Which type of correlation does the scatter plot show
Answer:
D
Step-by-step explanation:
From the given scatter plot, it is positive correlation.
What is scatter plot?Scatter plots are used to observe and plot relationships between two numeric variables graphically with the help of dots. The dots in a scatter plot shows the values of individual data points.
Interpretation of correlation
A scatter plot with increasing values of both variables can be said to have a positive correlation. A scatter plot with an increasing value of one variable and a decreasing value for another variable can be said to have a negative correlation.From the given graph,
The coordinates points are in increasing order.
Therefore, the correlation is positive.

Write the equation of the line passing through the point (−3,−4) that is perpendicular to y=8/3x+5.
Answer:
y = -3/8x -41/8
Step-by-step explanation:
Perpendicular lines intersect at 90° and their slopes are opposite reciprocals.
Therefore the slope changes from 8/3 to -3/8.
Now we must solve for the new y-intercept (b) by plugging in the given coordinate (-3,-4).
The result is b = -41/8 so our new equation is:
y = -3/8x -41/8

Answer: [tex]98.26[/tex]
Step-by-step explanation:
Given
Current population of tulips is 20
Each year it grows 70%
Field can sustain 300 tulips

What does factoring a polynomial involve?
Answer:
ANSWER BELOW↓
Step-by-step explanation:
Factoring a polynomial involves writing it as a product of two or more polynomials. It reverses the process of polynomial multiplication. We have seen several examples of factoring already. However, for this article, you should be especially familiar with taking common factors using the distributive property.
In 2003, 520,000 acres of farmland in a region were devoted to growing nuts. By 2012 ,the number of acres used to grow nuts had increased 820,000.Find the average rate of change in the number of acres in a region used to grow nuts from 2003 to 2012.
Answer:
Average rate of change = 33,333.33acre per year
Step-by-step explanation:
Given:
Farm land in 2003 = 520,000 acre
Farm land in 2012 = 820,000 acre
Find:
Average rate of change
Computation;
Number of year = 2012 - 2003
Number of year = 9 year
Average rate of change = [Farm land in 2012 - Farm land in 2003] / Number of year
Average rate of change = [820,000 - 520,000] / 9
Average rate of change = [300,000] / 9
Average rate of change = 33,333.33acre per year

Find the hypotenuse of the triangle. That is also the length of the rectangle.
Then use Pythagoras to find x.
Givens and solution
two sides of the triangle both = to 6
Find the base of the triangle which is also the length of the rectangle. Call the base = y
6^2 + 6^2 = y^2
36 + 36 = y^2
y^2 = 72
sqrt(y^2) = sqrt(72)
y = 8.4853
Transfer x to the opposite side of the rectangle.
x^2 = diagonal^2 - y^2
x^2 = 9^2 - y^2
x^2 = 81 - 72
x^2 = 9
sqrt(x^2)= sqrt(9)
x = 3
