P(Chocolate) for first draw = 2/5
P(Chocolate) for second draw = 1/4
Prob. of choosing two chocolate candies = 2/5 * 1/4 = 1/10
Probability of choosing two chocolates candies without replacement is equals to (1/ 10).
What is probability?
" Probability is defined as the mathematical expression which represents the ratio of number of favourable outcomes to the total number of outcomes for a given event."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Total number of candies = 5
Number of chocolates = 2
As per the condition of without replacement we have,
Probability of drawing a first chocolate = 2 / 5 ___( 1 )
Probability of second chocolate without replacing first one = 1/ 4 __( 2)
From ( 1 ) and (2) we get,
Probability of choosing 2 chocolates candies without replacement
= [tex]\frac{2}{5}[/tex] × [tex]\frac{1}{4}[/tex]
= (1 / 10)
Hence, probability of choosing two chocolates candies without replacement is equals to (1/ 10).

Use the distributive property to write the expression without parentheses.
6(5a - 3)
(Simplity your answer.)
Answer:
30a-18
it is as siplified as possible
Answer:
30a - 18
Step-by-step explanation:
What's the distributive property?
The distributive property is a property of math that helps with multiplication, usually in the form a(b + c). When using this property, a number, a, is distributed to the terms inside the parentheses, like b and c.Given the information above, let's simplify 6(5a - 3).
[tex](6)(5a) + (6)(-3)[/tex] [tex]30a - 18[/tex]Therefore, the answer is 30a - 18.

One roll of wallpaper covers 300 square feet. What is the least number of rolls of wallpaper needed to cover the walls of a room in the shape of a rectangular prism with a length of 15 feet, a width of 15 feet, and a height of 9 feet?
Answer: 1.8sqft
Step-by-step explanation:
It says just walls not top and bottom so if you just find the area of the left (135), right(135), front(135) and back(135) you divide 135 by 300 and get 0.45 then you multiply that by 4 0.45x4=1.8

Answer:
1) 5.20 if rounded
2) 123.04 if rounded
3) 16.17 if rounded
Step-by-step explanation:
1) tan (30) = x/9
x = tan (30) (9)
x = 5.1961... (5.20 if rounded)
2) sin (25) = 52/x
x = 52/sin(25)
x = 123.0424... (123.04 if rounded)
3) cos (18) = x/17
x = cos (18) (17)
x = 16.1679... (16.17 if rounded)

Answer:
8 = m, No solution
Step-by-step explanation:
1. -88 = -3(4m + 5) - (1 - 3m)
-88 = -12m - 15 - 1 + 3m : distributed into parentheses
-88 = -9m - 16 : combined like terms
+16 + 16 : adding to cancel out
-72 = -9m
/-9 /-9 : dividing by -9 to cancel
8 = m
2. -4(5k - 7) + 2k = -2(9k + 5)
-20k + 28 + 2k = -18k - 10 : distributed into parentheses
-18k + 28 = -18k - 10 : combined like terms
+ 10 + 10 : adding to cancel out
-18k + 38 = -18k
+18k +18k : adding to cancel out
38 = 0k (No solution)

Does anyone know what number 7 is I’m very confused.
Answer: [tex]\huge\boxed{5 \text{ prices}}[/tex]
Step-by-step explanation:
Because the mean is simply the mathematical average of all the points, simply add all the prices and divide by the amount of prices, or 10.
100 + 150 + 80 + 240 + 130 + 170 + 210 + 165 + 275 + 90 = 1610, then divide by 10 to get 1610 / 10 = 161.
Because there is a absolute deviation of 50 from the mean, simply subtract and add fifty to learn that the least they will pay is $111, and the most they will pay is $211, and 5 prices fall within this range.
find the equation of a parabola with a vertex of (2,8) and passes through the point (10,-4)?
Answer:
[tex]\displaystyle y = -\frac{3}{16}\, (x - 2)^{2} + 8[/tex].
Step-by-step explanation:
In general, if the vertex of a parabola is [tex](h,\, k)[/tex] (where [tex]h[/tex] and [tex]k[/tex] are constants,) the equation of that parabola would be [tex]y = a\, (x - h)^{2} + k[/tex] for some constant [tex]a[/tex] ([tex]a \ne 0[/tex].) This equation is the vertex form equation of this parabola.
In this question, it is given that the vertex of this parabola is [tex](2,\, 8)[/tex]. Thus, [tex]h = 2[/tex] and [tex]k = 8[/tex]. The equation of this parabola would be [tex]y = a\, (x - 2)^{2} + 8[/tex] for some constant [tex]a[/tex].
Finding the value of this constant [tex]a[/tex] requires the coordinates of a point on this parabola other than the vertex [tex](2,\, 8)[/tex].
Since [tex](10,\, -4)[/tex] is a point on this parabola, [tex]x = 10[/tex] and [tex]y = (-4)[/tex] should satisfy the equation of this parabola [tex]y = a\, (x - 2)^{2} + 8[/tex].
Thus:
[tex](-4) = a\, (10 - 2)^{2} + 8[/tex].
Solve this equation for [tex]a[/tex]:
[tex]\displaystyle a = -\frac{3}{16}[/tex].
Thus, the equation of this parabola in vertex form would be:
[tex]\displaystyle y = -\frac{3}{16}\, (x - 2)^{2} + 8[/tex].

=================================================
Explanation:
mu = population mean = 1300
sigma = population standard deviation = 20
Compute the z score based on x = 1330
z = (x-mu)/sigma
z = (1330-1300)/20
z = 30/20
z = 1.5
Asking to compute P(X < 1330) is the same as P(Z < 1.5) in this specific context when mu = 1300 and sigma = 20.
Use a Z table or a calculator to find that P(Z < 1.5) is roughly 0.93319
About 93.319% of the 755 bulbs are expected to last less than 1330 hours.
0.93319*755 = 704.55845
That value rounds to 705

The volume of a right cylinder is 27π cubic centimeters, and the high is 3 centimeters (cm). What is the radius of the cylinder?
A. 2 Cm
B. 3 Cm
C. 4.5 cm
D. 9 Cm
Answer:
B
Step-by-step explanation:
The volume is the height x area of base, 27pi / 3 = 9pi
Area of base is radius square x pi, 9 pi = 3^2 x pi
The radius of a cylinder with volume of 27π is 3 centimetres.
How to solve for volume of a cylinder?volume of a cylinder = πr²h
where
r = radiush = heightTherefore,
r = ?
h = 3 cm
volume = 27π
Hence,
27π = π × r² × 3
divide both sides by 3π
r² = 27π / 3π
r² = 9
r = √9
r = 3 cm
