Erik has 5 blue marbles and 13 red marbles in a box. He randomly draws one out. Find P(Red) in fraction form.
Answer:
13/5
Step-by-step explanation:
The probability of (red) is the chance of drawing a red marble out of the red and blue marbles. As there are 13 red marbles and 5 blue marbles, the probability of drawing a red marble is 13 out of 5, or 13/5 in fraction form.

The base of a solid is the region enclosed by the graphs of y=e^x, y=0, x=0, and x = 1. If each cross-section perpendicular to the x-axis is an equilateral triangle, then the volume is
(A) sqrt(3)/8(e^2-1)
(B) sqrt(3)/4(e^2-1)
(C) sqrt(3)/2(e^2-1)
PLS EXPLAIN
Answer:
A
Step-by-step explanation:
The base of a solid in the region enclosed by the graphs of y = eˣ, y = 0, x = 0, and x = 1. Each cross-section perpendicular to the x-axis is an equilateral triangle. We want to find the volume of the solid.
Please refer to the graph below. We are concerned with the red region.
In order to find the volume, we essentially sum up the area of the figure at each x value. So, we integrate from x = 0 to x = 1.
The area for an equilateral triangle is given by:
[tex]\displaystyle A=\frac{\sqrt{3}}{4}s^2[/tex]
Where s is the side length of the triangle.
Since the triangle lies perpendicular on the region, the side length of the triangle at x is simply y, which is eˣ.
Therefore, our volume is:
[tex]\displaystyle V=\int_0^1\frac{\sqrt3}{4}(y)^2\, dx[/tex]
Substitute:
[tex]\displaystyle V=\int_0^1\frac{\sqrt3}{4}(e^x)^2\, dx[/tex]
Evaluate the integral. Simplify:
[tex]\displaystyle V=\frac{\sqrt3}{4}\int_0^1e^{2x}\, dx[/tex]
Integrate using u-substitution:
[tex]\displaystyle V=\frac{\sqrt3}{8}\left(e^{2x}\Big|_0^1\right)[/tex]
Evaluate:
[tex]\displaystyle V=\frac{\sqrt3}{8}\left(e^{2(1)}-e^{2(0)} \right)[/tex]
Therefore, the volume of the solid is:
[tex]\displaystyle V=\frac{\sqrt3}{8}\left(e^2-1\right)[/tex]
Our answer is A.
Answer:
A.) sqrt(3)/8(e^2-1) is the answer.

#CarryOnLearningHi, I need the are to this question, I just need to show my work btw
"A driving instructor is investigating whether the time a driver spends in a driverâs education course improves their score on the driverâs test. The instructor randomly selected 10 drivers from a driverâs education course and recorded the number of hours each driver attended the driverâs education course and their corresponding score on the driverâs test. Assuming all conditions for inference are met, which of the following significance tests should be used for the investigation?"
a. A chi-square test of independence
b. A two-sample t-test for a difference between means
c. A two-sample z-test for a difference between proportions
d. A linear regression t-test for slope
e. A matched pairs t-test for a mean difference
Answer:
e. A matched pairs t-test for a mean difference
Step-by-step explanation:
When the observations from two samples are paired either naturally or by design we find the differences between the two observations of each pair.Treating the differences as a random sample from a normal population with mean ud= u1-u2 and unknwn standard deviation σd we perform one sample t- test on them. This is called the paired difference t- test or a paired t- test.
Suppose 10 young recruits are given a physical training by the Army . Their weights are recorded before and after the training. These observations constitutes natural pairing .
When we eliminate the undesireable sources of variation to take observations in pairs , this is called pairing by design.
Determine whether each ordered pair is a solution of the system of linear equations.
3y = 6x + 12
2x - y = -4
a. (-3,2)
b. (0,4)
a. Is (-3,2) a solution?
0 Yes
Ο Νο
b. Is (0,4) a solution?
O No
0 Yes
Answer:
(0,4)
Step-by-step explanation:
The given equations are :
3y = 6x + 12
2x - y = -4
If (-3,2) be the solution of the above equations,
3(2) = 6(-3) + 12
6 = -18+12
6≠ -6
2x - y = -4
2(2) -(-3) =-4
4+7 = -4
11 ≠ -4
No, (-3,2) is not the solution.
Similarly, put (0,4) in the abve equations,
3(4) = 6(0) + 12
12 = 12
and
2(0) - 4 = -4
-4 = -4
Hence, (0,4) is a solution of the given equations.
find the value for x
Answer:
X = 6°
Step-by-step explanation:
In a set of parallel lines, the opposite angles and corresponding angles are similar. Since the opposite angle of 110° is the corresponding angle of 19x - 4, you can conclude that 19x - 4 = 110° ⇒ 19x = 114° ⇒ x = 6°.

bottom of the tower?
a. 74 feet

c. 446 feet
d. 47 feet
I'm unsure how to solve for w, can someone please help?
Answer:
w = 1/2
Step-by-step explanation:
One of the ways to solve problems using log is to use these two equations that use the same variables and plug in numbers.
log b (a) = c
b^c = a
By plugging in the numbers we get this:
log 16 (4) = w
16^w = 4
w = 1/2

Isaiah has 2 3/5 cups of dough to make dumplings. If he uses 1/5 cup of dough for each dumpling, how many dumplings can Isaiah make?
Answer:
Step-by-step explanation:
You can convert 2 3/5 into 13/5 because 5/5 = 1 and 10/5 = 2.
Now that you have 13/5, you will see it’s much easier to divide! There are thirteen fifths cups of dough and he needs one fifths cups of dough for each dumpling. This means he can make 13!
A 5-pound bag of sugar costs $3.90. What is the unit rate?
Me.Bernstein will cut 8 pies into pieces that are each 1/6 of the whole After he cuts the 8 pies. how many pieces will Mr.Bernstein have
9514 1404 393
Answer:
48
Step-by-step explanation:
If each piece is 1/6 of the whole pie, then the whole pie has been divided into 6 equal pieces. The number of pieces resulting from 8 pies being cut that way is ...
(8 pies)(6 pieces/pie) = 8×6 pieces = 48 pieces
