What is the base area of a cylinder with a volume of 150 cubic cm and a height of 10 cm?
Final answer:
The base area of a cylinder with a volume of 150 cubic cm and a height of 10 cm is 15 square centimeters, obtained by dividing the volume by the height.
Explanation:
To find the base area of a cylinder with a known volume and height, we can use the formula for the volume of a cylinder: V = πr²h, where V is the volume, r is the radius of the base, and h is the height. Since the volume (V) is 150 cubic cm and the height (h) is 10 cm, we can rearrange the formula to solve for the base area (A): A = V/h.
By substituting the given values into our rearranged formula, we get: A = 150 cm³ / 10 cm = 15 cm². Thus, the base area of the cylinder is 15 square centimeters.
Which sequence represents an arithmetic sequence?
A −5, −7, −10, −14, −19, …
B 1.5, −1.5, 1.5, −1.5, …
C 4.1, 5.1, 6.2, 7.2, …
D −1.5, −1, −0.5, 0, …
Answer:
D
Step-by-step explanation:
We know that an arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is always constant.
−5, −7, −10, −14, −19, …
Here difference between -5 and -7 is -2
But difference between -10 and -7 is -3
⇒ Difference is not constant.
Therefore, this sequence does not represents an arithmetic sequence.
1.5, −1.5, 1.5, −1.5, …
Here difference between 1.5 and -1.5 is 3
But difference between -1.5 and 1.5 is 3
⇒ Difference is not constant.
Therefore, this sequence does not represents an arithmetic sequence.
4.1, 5.1, 6.2, 7.2, …
Here difference between 4.1 and 5.1 is 1
But difference between 6.2 and 5.1 is 1.1
⇒ Difference is not constant.
Therefore, this sequence does not represents an arithmetic sequence.
−1.5, −1, −0.5, 0, …
Here difference between -1.5 and -1 is 0.5
But difference between -1 and -0.5 is 0.5
⇒ Difference is constant.
Therefore, this sequence represents an arithmetic sequence.

Which of the following expressions represents the distance between Mona and the whale?
Choose 1 answer:
Answer:
A
Step-by-step explanation:
i promise it's A.
Mona is hang gliding 1.25 kilometers above sea level and a whale is 0.2 kilometers below sea level. The total distance between them is the sum of both distances, which is 1.45 kilometers.
Explanation:The distance between Mona and the whale is given by the sum of 2 distances. One is Mona's altitude above sea level (5/4=1.25 kilometers) and the other is the whale's depth below sea level (0.2 kilometers). Both values should be added because both distances are defined with respect to the sea level, and their signs indicate direction rather than distance. Therefore, the expression that represents the distance between Mona and the whale is 1.25 km+0.2 km = 1.45 km, where 1.25 km is the distance Mona is gliding above the sea level and 0.2 km is the distance the whale is under the sea level.

Which is a factor of x2 + 8x – 48? (x – 6) (x + 4) (x – 16) (x + 12)
Answer:
(x+12)
Step-by-step explanation:
The middle number is 8 and the last number is -48.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 8
Multiply together to get -48
Can you think of the two numbers?
Try -4 and 12:
-4+12 = 8
-4*12 = -48
Fill in the blanks in
(x+_)(x+_)
with -4 and 12 to get...
(x-4)(x+12)
But, since (x-4) isn't an option, the answer would be (x+12)

Fractions is equipment to 3/8
Answer:
Step-by-step explanation:
It is eqivilent to 37.5
I think you meant to say "equivalent" instead of "equipment"
To find equivalent fractions to 3/8, you would multiply top and bottom by the same number.
If we multiply the top and bottom by 5 for instance, then
3*5 = 15
8*5 = 40
So 3/8 is equivalent to 15/40
--------------
Another example: multiply top and bottom by 9
3*9 = 27
8*9 = 72
This means 3/8 is equivalent to 27/72
-------------
Now let's say you were asked if 15/40 was equivalent to 3/8
To check this, you would assume they are equal, then cross multiply like so
15/40 = 3/8
15*8 = 40*3 ... cross multiply
120 = 120
Since we end up with the same thing on both sides, we have confirmed that 15/40 = 3/8 is a true equation.
A circle has a sector with area 1/2 pi and central angle of 1/9 pi radians. What is the area of the circle
Answer:
[tex]9\pi[/tex] sq. units.
Step-by-step explanation:
It is given that a circle has a sector with area [tex]\frac{1}{2}\pi[/tex] and central angle of [tex]\frac{1}{9}\pi[/tex] radians.
We know that, the area of sector is
[tex]A=\dfrac{1}{2}r^2\theta[/tex]
where, r is radius and [tex]\theta[/tex] is central angle in radian.
Substitute the values of A and [tex]\theta[/tex].
[tex]\dfrac{1}{2}\pi=\dfrac{1}{2}r^2(\dfrac{1}{9}\pi)[/tex]
[tex]1=r^2(\dfrac{1}{9})[/tex]
[tex]9=r^2[/tex]
[tex]3=r[/tex]
The radius of the circle is 3 units.
So, the area of circle is
[tex]A=\pi r^2[/tex]
[tex]A=\pi (3)^2[/tex]
[tex]A=9\pi[/tex]
Therefore, the area of circle is [tex]9\pi[/tex] sq. units.

To plot the point (3,4) on a scatter plot, which of the following steps should you follow? move three places vertically and four places horizontally move three places horizontally and four places vertically move three places vertically and three places horizontally move four places horizontally and four places vertically
Answer:
You should move 3 places horizontally, and 4 places vertically.
Step-by-step explanation:
Final answer:
To plot the point (3,4) on a scatter plot, you should follow:
Move three places horizontally and four places vertically.Explanation:
To plot the point (3,4) on a scatter plot, you should follow these steps:
First, move three places horizontally from the origin along the x-axis; this represents the x-coordinate of the point. Next, from that position, move four places vertically along the y-axis; this represents the y-coordinate of the point.
By doing this, you will have plotted the point (3,4) correctly on the scatter plot.
This process is based on the convention that the first number in the ordered pair (x,y) corresponds to the horizontal (x-axis) movement while the second number corresponds to the vertical (y-axis) movement.
Therefore, plotting a point on a scatter plot or any Cartesian plane involves finding the x-coordinate on the x-axis and then finding the y-coordinate on the y-axis and marking the point where these two meet.

Answer:
0.33
Step-by-step explanation:
because 0.45 plus 0.22 is 0.67 which means the other probability is 0.33.
The probability of dying from some other cause will be 0.33. Probability always lies between 0 and 1.
What is probability?The chances of an event occurring are defined by probability. Probability has several uses in games, in business to create probability-based forecasts,
The given data in the problem is;
P(A) is the probability of dying from cardiovascular disease = 0.45
P(B) is the probability of dying from cancer = 22
P is the probability of dying from some other cause =?
The probability of dying from some other cause will be found as;
[tex]\rm P =1- P(A)+P(B) \\\\ \rm P =1- 0.45+0.22 \\\\ \rm P =0.33[/tex]
Hence the probability of dying from some other cause will be 0.33.

The data shown has a least-squares regression line of y=3.2x−6.4.
Use the drop-down menus to complete the statements and identify the residual of the data point (8,19.2).
Point (8,19.2) is ___ the least-squares regression line.
A. on
B. below
C. above
The value of the least-squares regression line at x=8 is ___.
A. -6.4
B. 0
C. 12
D. 19.2
E. 25.6
So, the residual of the data point (8,19.2) is ____.
A. -19.2
B. -12
C. 0
D. 12
E. 19.2
Answer:
1) B. on, 2) D. 19.2, 3) C. 0
Step-by-step explanation:
1) The value of y according to the regression line is:
[tex]y = 3.2\cdot (8) - 6.4[/tex]
[tex]y = 19.2[/tex]
Hence, the point (8,19.2) is on the least-squares regression line.
2) The value of y according to the regression line is 19.2.
3) The residual is the difference between the value from the regression line and the real value. In this case, the residual value is 0.
Final answer:
The data point (8,19.2) lies on the least-squares regression line. The value of the least-squares regression line at x=8 is 19.2. Hence, the residual of the data point (8,19.2) is 0.
Explanation:
The data point (8,19.2) is on the least-squares regression line since when we substitute x=8 into the equation y=3.2x−6.4, we get y=3.2(8)−6.4 which simplifies to y=25.6−6.4, yielding y=19.2, which is exactly the y-value of the given data point.
The value of the least-squares regression line at x=8 is therefore 19.2 which corresponds to option D.
Since the observed y-value is exactly predicted by the regression line at this x-value, the residual for the data point (8,19.2) is 0, which represents the difference between the observed y-value and the value predicted by the regression formula. Therefore, option C is correct for the residual.
