The surface area of the cylinder is 60π cm².
What is the surface area of a cylinder?
The surface area of a cylinder indicates the total area of two plane surfaces (bases) and one curved surface.
If a cylinder has a radius of r cm and height of h cm, then the total surface area of the cylinder = 2πr(r + h)
Given, r = 3 cm and h = 7 cm.
Therefore, the total surface area of the cylinder
= 2πr(r + h)
= 2π × 3(3 + 7) cm²
= 2π × 3 × 10 cm²
= 60π cm²

Complete the equations below to show how you can use the Pythagorean theorem to find the distance between these two points
Answer:
The distance would be [tex]\sqrt{97[/tex].
Step-by-step explanation:
The least distance between them would be to draw a straight line between them.
By calculating the distance between the y values and the x values, you can calculate the distance.
y values:
|5 - 1| = 4
x values:
|6 - -3| = 9
| | = the absolute value, meaning you change the final sign to positive.
Use the Pythagorean theorem [tex]a^2 +b^2=c^2[/tex] and substitute the numbers in.
[tex]4^2 + 9^2=c^2 \\c^2 = 97\\c=\sqrt{97[/tex]
Solve the equation.

Exercise 1. A batch of 400 containers for frozen orange juice contains 4 that are defective. Two are selected, at random, without replacement from the batch.
(1) What is the probability that the second one selected is defective given that the first one was defective?
(2) What is the probability that both are defective?
(3) What is the probability that both are non-defective?
Answer:
1. 1/13,300
2. 1/13,300
3. 2607/2660
Step-by-step explanation:
Probability is the ratio of the number of possible outcomes to the number of total outcome. The probability that an event will happen added to the probability of the same even not happening is 1.
Given that there are 400 containers of frozen orange juice with 4 that are defective,
non-defective = 400 - 4 = 396
Probability of selecting
Non-defective = 396/400 = 99/100
Defective = 4/100 = 1/100
the probability that the second one selected is defective given that the first one was defective is the same as the probability that both are defective
= 4/400 *3/399
= 1/13,300
the probability that both are non-defective
= 396/400 * 395/399
= 99/100 * 395/399
= 33*79/20*133
= 2607/2660

The amount of carbon-14 in an object is given by y = ae– 0.00012t where a is the initial amount of carbon and t is the age in years. A fossil bone contains 25% of its original carbon-14. What is the approximate age of the bone?
Answer:
The approximate age of the bone is approximately 11552 years.
Step-by-step explanation:
The current proportion of carbon-14 with respect to its original amount is defined by following formula:
[tex]\frac{y}{a} = e^{-0.00012\cdot t}[/tex] (1)
Where:
[tex]y[/tex] - Current amount of carbon-14, no unit.
[tex]a[/tex] - Initial amount of carbon-14, no unit.
[tex]t[/tex] - Time, in years.
If we know that [tex]\frac{y}{a} = 0.25[/tex], then the approximate age of the bone is:
[tex]t = -8333.333\cdot \ln \frac{y}{a}[/tex]
[tex]t\approx 11552.453\,yr[/tex]
The approximate age of the bone is approximately 11552 years.

An auto maker estimates that the mean gas mileage of its sports utility vehicle is at least 20 miles per gallon. A random sample of 36 such vehicles had a mean of 18 miles per gallon and a standard deviation of 5 miles per gallon. At α = .01 can you reject the auto maker's claim?
Answer:
Yes, we reject the auto maker's claim.
Step-by-step explanation:
H0 : μ ≥ 20
H1 : μ < 20
Sample mean, xbar = 18 ;
Sample size, n = 36
Standard deviation, s = 5
At α = 0.01
The test statistic :
(xbar - μ) ÷ s /sqrt(n)
(18 - 20) ÷ 5/sqrt(36)
-2 /0.8333333
= - 2.4
Pvalue from test statistic : Pvalue = 0.00819
Pvalue < α
0.00819 < 0.01
Hence, we reject the Null
Write an equation that shows the relationship 64% of y is 40.
PLEASE HELP
Answer:
[tex]0.64*y = 40[/tex]
Step-by-step explanation:
Answer:
64/100=40/y
Step-by-step explanation:
We use the simple equation of finding percentages, which would be the percentage (64) over 100 percent, as this is our total. If 64 percent of y equals 40, then the equation is 64/100=40/y. To solve for y, multiply 100 x 40= 4000, then divide by 64 to get the answer. Y=62.5

What is the equation of the following line? Be sure to scroll down first to see
all answer options.
(0,0) (10,-2)
The equation of the following line is y= -1/5x.
Option F is correct.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
From the graph we have the coordinates as (0, 0) and (10, -2)
So, the slope of the line is
= (-2 - 0) / (10- 0)
= -2/ 10
= 1-5
and, using the slope intercept is
y= mx+ b
y= -1/5x + b
Now, put x= 0 and y= 0 in above equation
0 = 1/5(0) + b
b= 0
So, the Equation of line is
y= -1/5x

|x+8|=x+8 what is x?
Answer:
x ≥ 0
Step-by-step explanation:
The absolute value of x+8 equals itself, thus x must be a real number (0 or any positive number).
The value of x in |x+8|=x+8 is -8.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
|x+8|=x+8
Now,
To solve this equation, we need to consider two cases:
Case 1: x+8 is positive or zero. Then |x+8|=x+8 and we can solve for x by subtracting 8 from both sides:
|x+8|=x+8
x+8=x+8
x=x
This means that any value of x is a solution in this case.
Case 2: x+8 is negative. Then |x+8|=-(x+8) and we can solve for x by adding 8 to both sides and dividing by -2:
|x+8|=-(x+8)
x+8=-(x+8)
2x=-16
x=-8
Therefore, by the given equation the answer will be -8.
