Answer:
[tex](\frac{1}{6})(\frac{1}{2} )=\frac{1}{12}[/tex]
Step-by-step explanation:
P(a no. less than 2) = 1/6
P(a head) = 1/2
Since both events are independent, multiplication of them is used.
A seagull is flying at a height of 10 feet above ocean. The seagull dives into the water to catch a fish that is at a depth of 6 feet. What is the change in elevation of the seagull?
Answer:
The change in elevation of the seagull is -16 ft
Step-by-step explanation:
Displacement
The displacement, unlike distance, considers the direction of the lengths occurring in the systems.
To solve the problem, we need to set a zero-level reference. Let's assume the sea level as zero height, any position above this reference as positive, and any position below this reference as negative.
The seagull is flying at a height of 10 ft above the ocean. Thus, its position is positive +10 feet.
The seagull then dives into the water to catch a fish at a depth of 6 feet. This position is negative: -6 ft.
The change in elevation is found by subtracting the final elevation and the initial elevation:
change = -6 ft - 10 ft = -16 ft
The change in elevation of the seagull is -16 ft

Triangle ABD and ACD are congruent based on HL congruence theorem
What are congruent figures?Two figures are said to be congruent of they have the same shape and all the corresponding sides and angles are congruent.
The HL (hypotenuse leg) congruence theorem states that if the hypotenuse and one leg of a triangle is congruent to another triangle, then both triangles are congruent.
In triangle ABD and ACD;
BD = CD and AD ≅ AD
Hence Triangle ABD and ACD are congruent based on HL congruence theorem

Stephen and Bridget win some money and share it in the ratio 4:1. Stephen gets £33 more than Bridget. How much did they get altogether?
Given:
Stephen and Bridget win some money and share it in the ratio 4:1.
Stephen gets £33 more than Bridget.
To find:
The money they get altogether.
Solution:
Let Stephen and Bridget will get the amount of 4x and x respectively.
Stephen gets £33 more than Bridget.
[tex]4x-x=33[/tex]
[tex]3x=33[/tex]
Divide both sides by 3.
[tex]x=11[/tex]
Now,
Stephen get: [tex]4(11)=44[/tex]
Bridget get: [tex]11[/tex]
Total amount = [tex]44+11=55[/tex]
Therefore, the amount they will get altogether is £55.

What is the slope of a line that passes through the points (-2,4) and (-6, 12)?
-2
2
-1/2
1/2
Answer:
-2
Step-by-step explanation:
first, you want to graph your points on a graph. A really good online graphing calculator i like is called desmos.
next, slope is rise over run. count how many units up or down from leftmost point to the other. in this case it is -8.
third, find the run part of the slope by counting units right or left from the leftmost point to the other. in this case it is 4.
last, but the two numbers together in a fraction and simplify. rise over run.
-8/4 which simplifies to -2/1 which is the same thing as -2
What are the real and complex solutions to the following equation? -2x^4+2x^2+4=0
Show all steps.
u=±1i or u=±√2
u=±2i or u=±√2
Answer:
x = ± i, x = ± [tex]\sqrt{2}[/tex]
Step-by-step explanation:
Given
- 2[tex]x^{4}[/tex] + 2x² + 4 = 0 ( divide through by - 2 )
[tex]x^{4}[/tex] - x² - 2 = 0
Use the substitution x² = u , then
u² - u - 2 = 0 ← in standard form
(u - 2)(u + 1) = 0 ← in factored form
Equate each factor to zero and solve for u
u - 2 = 0 ⇒ u = 2
u + 1 = 0 ⇒ u = - 1
Change back into terms of x, that is
x² = 2 ( take the square root of both sides )
x = ± [tex]\sqrt{2}[/tex]
x² = - 1 ( take the square root of both sides )
x = ± [tex]\sqrt{-1}[/tex] = ± i
x = ± [tex]\sqrt{2}[/tex] ← real solutions
x = ± i ← complex solutions
what is the expression for the probability when the disease D is present but the test says its not? P = Event that test is positive, D = Event disease is present
Answer:
[tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]
Step-by-step explanation:
Given
P = Test is positive
D = Disease is present
Required
Write an expression when disease is present but test says that the disease is not present
The above statement can be split to two
Disease is Present & Test is not positive
The first statement:
Disease is Present means D
The second statement
Test is not positive means not P
Mathematically;
not P means P' or [tex]P^c[/tex]
So, the required expression is: [tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

Which of the following lists the sides of △DEF in order from shortest to longest?
Answer:
The 2nd option.
Step-by-step explanation:
Since Angle D is 68 degrees side EF would be the longest.
Side DF is the shortest side it is opposite the smallest angle.
Side EF is in the middle since opposite the next biggest angle.
Side EF is again the longest since Angle D is the biggest at 68 degrees.

Reese is using a coin to predict the gender of the puppies born to her dog. According to Reese's model, which is the probability that a litter of 5 puppies will be all males? StartFraction 1 over 32 EndFraction StartFraction 1 over 16 EndFraction StartFraction 1 over 10 EndFraction One-half
Answer:
[tex]\frac{1}{32}[/tex]
Step-by-step explanation:
According to Reese's model, let the head of the coin represent male, and the tail represents female. The outcome can either be a male or a female.
Total outcome = 2
pr(male) = [tex]\frac{1}{2}[/tex]
pr(female) = [tex]\frac{1}{2}[/tex]
Therefore the probability of male equals the probability of females i.e [tex]\frac{1}{2}[/tex].
Therefore,
pr(a litter of 5 puppies will be males) = [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex]
= [tex]\frac{1}{32}[/tex]
According to Reese's model, the probability that a litter of 5 puppies will be males is [tex]\frac{1}{32}[/tex].
