Answer:
0.4196
0.2098
0.0280
0.2378
Step-by-step explanation:
Given that:
Number of females = 8
Number of males = 6
Total = 8 + 6 = 14
Number of positions = 5
Probability = required outcome / Total possible outcomes
Total possible outcomes = 14C5
nCr = n! / (n-r)! r!
14C5 = 2002 (from calculator)
(A) 3 females and 2 males?
Required outcome : 8C3 * 6C2 = 56 * 15 = 840
840 / 2002 = 0.4196
(B) 4 females and 1 male?
(8C4 * 6C1) / 14C5 = 420 / 2002 = 0.2098
(C) 5 females?
8C5 / 14C5 = 56 / 2002 = 0.0280
(D) At least 4 females?
4 female 1 male + 5 females
((8C4 * 6C1) + 8C5) / 14C5
(420 + 56) / 2002 = 0.2378

Jason used 0.5 cup of kernels to make 16 cups of popcorn how many cups of popcorn would he make if he used 0.75 cup of kernels.
A. 32
B. 28
C. 24
D. 20
PLEASE HELP ME IM DAILING MATH
Answer:
Option C: 24 is the correct answer.
Step-by-step explanation:
Given that:
Jason used 0.5 cup of kernels to make 16 cups of popcorn
Ratio of cup of kernel to cups of popcorn = 0.5 : 16
Let,
x be the cups of popcorn made from 0.75 cups of kernel
Ratio of cups of kernel to cups of popcorn = 0.75 : x
This is a direct proportion as the cups of kernel is increasing.
0.5 : 16 :: 0.75 : x
Product of mean = Product of extreme
16*0.75 = 0.5x
12=0.5x
0.5x=12
Dividing both sides by 0.5
[tex]\frac{0.5x}{0.5}=\frac{12}{0.5}\\x=24[/tex]
Jason can make 24 cups of popcorn from 0.75 cups of kernel.
Hence,
Option C: 24 is the correct answer.

A submarine hovers at 66 and two-thirds yards below sea level. If it ascends 24 and StartFraction 1 over 8 EndFraction yards and then descends 78 and three-fourths yards, what is the submarine's new position, in yards, with respect to sea level?
Answer:
- 121 7/24
Step-by-step explanation:
Initial Position = 66 2/3 below sea level
Ascent = 24 1/8
Descent = 78 3/4
New position of submarine :
Since initial. Position is below sea level, we finite with a negative sign :
-66 2/3 = - 200 /3
Ascent is positive ; 24 1/8 = 193 / 8
-200 /3 + 193 / 8
(-1600 + 579) / 24
= - 1021 / 24
Descent = 78 3/4 (negative) downward
78 3/4 = - 315/ 4
-1021 / 24 - 315/4
(-1021 - 1890) / 24
= - 2911 / 24
= - 121 7/24
121 7/24 below sea level
A wire is attached to a 425-foot tower that is perpendicular to the ground. The wire makes an angle of 26.5o to the ground. what is the length of the wire in feet
Answer
952.49feet
Step-by-step explanation:
This set up will be a right angled triangle
Height = opposite side = 425foot
Length of wire = hypotenuse= x
Angle of elevation= 26.5°
Using the SOH identity
Sin 26.5 = opp/hyp
Sin26.5 = 425/x
x = 425/sin26.5
x =425/0.4462
x = 952.49feet
Hence the length of the wire is 952.49feet
Let $r$ and $s$ be the roots of $3x^2 + 4x + 12 = 0.$ Find $r^2 + s^2.$
Use a similar strategy as in your other question, [19925664].
3x² + 4x + 12 = 3 (x - r ) (x - s)
3x² + 4x + 12 = 3 (x² - (r + s) x + rs)
3x² + 4x + 12 = 3x² - 3 (r + s) x + 3rs
so that
r + s = -4/3
rs = 12/3 = 4
Recall that
(r + s)² = r² + 2rs + s²
so that
r² + s² = -2rs = -2(4) = -8

An airplane is flying from nyc to la. The distance it travels in miles,d, is related to the to the time in seconds, t, by the equation d=0.15t
Answer:
It will cover 4.5 miles in 30 seconds.
Step-by-step explanation:
An airplane is flying from nyc to la.
The distance it travels in miles,d, is related to the to the time in seconds, t, by the equation :
d=0.15t ...(1)
Let us assume we need to find the distance at t = 30 s.
Put t = 30 s in equation (1).
d=0.15 × 30
d = 4.5 miles
Hence, it will cover 4.5 miles in 30 seconds.

Answer:
[tex]x^2-10x+8=0[/tex]
Step-by-step explanation:
[tex]\frac{1}{x} +\frac{1}{x-2}=\frac{1}{4} \\\\\frac{x-2+x}{x(x-2)} = \frac{1}{4} \\\\\frac{2x-2}{x(x-2)}=\frac{1}{4} \\\\4(2x-2)=x(x-2)\\8x-8=x^2-2x\\0=x^2-2x-8x+8\\0=x^2-10x+8\\x^2-10x+8=0\\[/tex]
Using the least common denominator in simplifying the rational equation, the result of in standard form is: [tex]\mathbf{x^2 -10x + 8 = 0}[/tex]
What is the Least Common Denominator (LCD)?Least common denominator is the smallest common multiple of the denominators of two or more fractions.It is useful when simplifying, adding, subtracting or comparing fractions.Given:
[tex]\frac{1}{x} + \frac{1}{x - 2} = \frac{1}{4}[/tex]
The least common denominator of the two fractions on the left side of the equation is x(x - 2).
Thus:
[tex]\frac{1(x - 2) + x(1)}{x(x - 2)} = \frac{1}{4}\\\\\frac{x - 2 + x}{x(x - 2)} = \frac{1}{4}\\\\\frac{2x - 2}{x^2 - 2x)} = \frac{1}{4}[/tex]
Cross multiply[tex]4(2x + 2) = 1(x^2 - 2x)\\\\8x + 8 = x^2 - 2x\\\\[/tex]
Rewrite in standard form[tex]0 = x^2 - 2x - 8x + 8\\\\0 = x^2 -10x + 8\\\\\mathbf{x^2 -10x + 8 = 0}[/tex]

Domain of a function is a set of x-values (input values) for which the function is defined.
Range of a function is a set of y-values (output values) for the given set of input values.
7). Domain → (-∞, ∞)
Range → (-∞, ∞)
8). Domain → (-∞, ∞)
Range → [-2, ∞)
9). Domain → [-2, 2]
Range → [-3, 3]
10). Domain → (-∞, ∞)
Range → [-1, 1]
Identify the domain of the function shown in the graph.
A. -5<x<5
B. 0<x<5
C. x is all real numbers.
D. x > 0
Answer:
The answer is A choice.
Explanation:
By looking at the graph, we notice that at the left side, the domain/x-value stops at -5 and 5.
Thus, the domain is at the left end side to the right end side.
The domain stops at -5 on the left side and 5 on the right side. Thus the answer is
-5 < x < 5.
The A choice.
Understanding
The domain of a function is basically all the values where x is defined, and by defined, it means it has a y value corresponding to it. In this graph, x is defined from -5 to 5. If you look outside this range of numbers (from -5 to 5 on the x-axis) you will not find any y values for them. We can easily say the solution is A.
Solution:
[A] [tex]-5<x<5[/tex]
Note: From what I see from the picture -5 and 5 are included in the domain, either the question is incorrectly written, or the picture isn't clear enough. If so, the answer should be [tex]-5\leq x\leq 5[/tex].
