A bag contains 5 blue marbles, 2 green marbles, and 3 yellow marbles. What is the probability of choosing one green marble and then a yellow marble with replacement? 3/50 1/15 1/2 6/10
Answer:
Step-by-step explanation:
Total number of marbles = 5 + 2 + 3 = 10
Probability of choosing 1 green marble = 2/10
Probability of choosing 1 yellow marble = 3/10
Notice (and this is important) that the denominator didn't change. Why?
Because you replaced the first marble into the bag. That word replacement is critical in a problem of this nature. There is the term non replacement which means that the second draw would have a denominator of 9.
So what is the probability of P(green then yellow)?
P(green then yellow) = 3/10 * 2/10 = 6/100
Answer: P(green then yellow) = 3/50 because 6 / 100 reduces.
Todd plans to swim 18 laps in the pool. Each lap is 50 yards. So far, Todd has swam 738 yards. What percentage of the total has Todd completed?
Answer:
82%
Step-by-step explanation:

Find the sum of 150+143+136+…+(-102)+(-109) arithmetic series
Answer:
779
Step-by-step explanation:
Given Arithmetic series is: 150+143+136+…+(-102)+(-109)
Here,
First term (a) = 150
Common difference (d) = 143 - 150 = - 7
[tex]n^{th}\: term:\:a_n = -109[/tex]
The formula for [tex]n^{th}\: term[/tex] of an arithmetic series is given as:
[tex]a_n = a +(n-1)d[/tex]
Plugging the values of a, d and [tex]a_n[/tex] in the above formula, we will find the number of terms that exist from 150 to (-109)
[tex]-109 = 150+(n-1)(-7)[/tex]
[tex]\implies\: -109 -150=(n-1)(-7)[/tex]
[tex]\implies\: -259=(n-1)(-7)[/tex]
[tex]\implies\: \frac{-259}{-7}=(n-1)[/tex]
[tex]\implies\: 37=n-1[/tex]
[tex]\implies\: 37+1=n[/tex]
[tex]\implies\: n=38[/tex]
Thus, there are total 38 terms in the given Arithmetic series.
Now,
Sum of n terms of an arithmetic series is given by the formula: [tex]S_n=\frac{n}{2}(a +a_n)[/tex],
Plugging in the values, we find:
[tex]S_{38}=\frac{38}{2}[150 +(-109)][/tex]
[tex]\implies S_{38}=\frac{38}{2}[150 +(-109)][/tex]
[tex]\implies S_{38}=19[150 -109][/tex]
[tex]\implies S_{38}=19[41][/tex]
[tex]\implies S_{38}=779[/tex]
Which expression represents the height of the triangular base of the pyramid? five-halves startroot 2 endrootunits five-halves startroot 3 endrootunits 5 startroot 2 endrootunits 5 startroot 3 endrootunits

What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
The question is incomplete, and the upper part of the completed question is:
"The base of a solid oblique pyramid is an equilateral triangle with an edge length of 5 units. A solid oblique pyramid has an equilateral triangle base with an edge length of 5 units. "
The diagram of the base of the considered pyramid is attached below.
The perpendicular from A to BC is touching BC at C, and is bisecting it (it can be proved).
Consider the triangle ADB. It is a right angled triangle.
We need the length of AD which represents the height of the triangle ABC.
This is obtained using Pythagoras theorem as:
[tex]|AB|^2 = |AD|^2 + |DB|^2\\\\|AD|^2 = |AB|^2 - |DB|^2\\\\|AD| = \sqrt{5^2 - \left( \dfrac{5}{2}\right)^2}[/tex]
(took positive root because of |AD| being length, which is a non-negative quantity).
SImplifying it, we get:
[tex]|AD| = \sqrt{5^2 - \left( \dfrac{5}{2}\right)^2}\\\\|AD| = \sqrt{\dfrac{5^2(4-1)}{4}} = \dfrac{5\sqrt{3}}{2} = \dfrac{5}{2} \times \sqrt{3} \: \rm units[/tex]

A movie theater sells two sizes of popcorn, large and small, in bags shaped like rectangular prisms. The small bag has a height of 5.5 inches, a length of 5 inches, and a width of 3 inches. The large bag has the same width and length as the small bag, but two times the volume. What is the height of the large bag of popcorn?
the solution is:
u should at the first find the volume of the small bag that V= LWH ( Lenght, width, height)
so it will be 82.5
since the Volume of the large bag is 2 times the volume of the small bag so the volume of large bag will be 165
so H = V / LW
H = 165 / 5×3
H = 165 / 15
So the Answer is H = 11

Given that a circle L, we radius 9 and a central angle of 120°, we need to find the area of the sector, which is intercepted by the central angle,
So,
The area of a sector of a circle = central angle / 360° × area of the circle,
So,
A = 120°/360° × π × 9²
= 1/3π × 81

Ms. Gartland bought x number of shirts for the new members of her chorus. The cost for x number of shirt, including $3.99 shipping was $77.49 each shirt cost 12.25 there was no sales tax on this purchase. which equation could be used to find?
Answer:
12.25s + 3.99 = 77.49 would be your equation used to find the amount of shirts purchased.
When we solve the equation, we get 6 which is the quantity of shirts Gartland purchased.
Step-by-step explanation:
We know the shirts were 12.25 but we didnt know how much she pruchased leaving our shirts (s) unknown.
We added 3.99 for shipping and our total cost was 77.49

Would the sum of the interior angles of a triangle in this type of geometry be different from those of triangle in Euclidean geometry? Explain.
Answer: Yes
Step-by-step explanation:
If a triangle was inscribed onto the surface of a sphere, the sum of its interior angles will not add up 180 degrees. This is actually a method in differential geometry to see if a surface is flat or curved; see if the angles up to 180 degrees. Now, it depends on how large the triangle is. If we were to draw a triangle on the surface of the earth with lets say a piece of chalk, the angles will appear to add up to 180 degrees. The larger amount of surface that the triangle covers, the larger deviation you will get from 180 degrees.
A triangle includes one angle that measures 72º. Which pair could be the measures of the other two angles of the triangle
A 9º , 9º C 53º , 55º
B 26º , 46º D 72º , 108º
Answer:
B
Step-by-step explanation:
180-72 = 108

Step-by-step explanation:
Answer: the earth moves around the sun
Step-by-step explanation:
The most direct observational evidence for Earth's orbital motion is the apparent shift of nearby stars after six months, as the Earth moves from one side of its orbit to the other. Because of the large distance to even the nearest start, this parallax shift is too small to been seen without a telescope.
