1) Let X represent the number of tires with low air pressure on a randomly chosen car. The probability of distribution of X is as follows:
X 0 1 2 3 4
P(X) 0.1 0.2 0.4 0.2 0,1
a) Find the probability of 1 tire with low air pressure P (1) =
b) Find the probability of more than 2 tires having low air pressure P (more than 2) =
c) P (all 4 tires) =
d) Compute the expected number of tires with low air pressure.
e) Compute the standard deviation for the number of tires with low air pressure.
Answer:
0.2 ; 0.3 ; 0.1 ; 2
Step-by-step explanation:
X 0 1 2 3 4
P(X) 0.1 0.2 0.4 0.2 0,1
a) Find the probability of 1 tire with low air pressure P (1) :
From probability distribution table Given :
P(1) = 0.2
b) Find the probability of more than 2 tires having low air pressure P (more than 2) =
P(x > 2) = p(3) + p(4)
P(x > 2) = 0.2 + 0.1 = 0.3
c) P (all 4 tires)
From the table :
P(x = 4) = 0.1
d) Compute the expected number of tires with low air pressure.
E(X) = Σx * p(x)
E(x) = (0*0.1) + (1*0.2) + (2*0.4) + (3*0.2) + (4*0.1) = 2

Why was the Tet Offensive considered a turning point in the Vietnam War? Check all that apply.
◯The US and South Vietnam reclaimed towns that were attacked.
◯President Johnson decided not to run for reelection.
◯Americans wanted the war to continue in Vietnam.
◯US confidence in winning the war was weakened.
◯Fighting communism was easy for troops in Vietnam.
Answer:
Its A, B, and D.
Step-by-step explanation:
The Tet Offensive considered a turning point in the Vietnam War because:
The US and South Vietnam reclaimed towns that were attacked.President Johnson decided not to run for reelection.US confidence in winning the war was weakened.What happen in Vietnam war?Troops from the United States and South Vietnam targeted North Vietnamese and Viet Cong hideouts in Cambodia and Laos.
Although being a military defeat, the Tet Offensive was a stunning propaganda win for communists. In fact, it is frequently regarded for changing the tide of the war in their favour.
As Viet Cong rebels invaded rural areas previously held by the South Vietnamese government, the South Vietnamese began to lose authority.
Despite tremendous deaths, North Vietnam secured a strategic triumph with the Tet Offensive, which represented a watershed moment in the Vietnam War and the start of the protracted, agonising American withdrawal from the region.

I like dogs but this question is a hard one.
Answer:
Work below
Step-by-step explanation:
49 total dogs.
36 more small dogs.
13 big dogs.
lol just realized today's school has sh*t wording and this question can be taken TWO ways. 36 more as in, 36 more dogs in total or 36 more small dogs than large dogs adding the amount of large dogs with this. this gives us 49.
the only way to get the x value (large dogs) and add this on top of the 36 (small dogs) and get 49 is to do 6.5 + 42.5 (36 + 6.5) this gives us 49.
Thanks guy in the comments for giving the second response, after some thinking i realized that i could also read it that way.
F** k today's hw and their wording
Answer:
6.5 Large Dogs
42.5 Small Dogs
Step-by-step explanation:
You simply do not have enough love for dogs to solve the question.
Luckily I have an extremely high affection for dogs so I can help.
S = amount of small dogs
L = amount of large dogs
S + L = 49
S = 36 + L
plug the second equation into the correct variable of the first equation so:
(36+L) + L = 49
36 +2L = 49
2L = 49-36
L = 6.5 *this doesn't make sense*
S = 42.5 *this also doesn't make sense*

Factor the number 81 :

Answer:
log₃(81) = 4
Step-by-step explanation:
There are a few ways you can go at this. Perhaps the simplest is to recognize that 81 is a power of 3.
log₃(81) = log₃(3⁴)
log₃(81) = 4

You can also use the "change of base" formula:
log₃(81) = log(81)/log(3) ≈ 1.908485/0.4771213
log₃(81) = 4

Rui is a professional deep water free diver. His altitude (in meters relative to sea level), xxx seconds after diving, is modeled by: d(x)=\dfrac12x^2 -10xd(x)= 2 1 x 2 −10xd, left parenthesis, x, right parenthesis, equals, start fraction, 1, divided by, 2, end fraction, x, squared, minus, 10, x How many seconds after diving will Rui reach his lowest altitude?
Answer:
Rui will reach his lowest altitude after 20seconds of diving
Step-by-step explanation:
Given the function that models the altitude of Rui at any time x expressed as:
d(x) = 1/2 x² - 10x
The height of rui at his lowest altitude will be zero. Substitute d(x) = 0 into the expression and get x
d(x) = 1/2 x² - 10x
0 = 1/2 x² - 10x
-1/2x² = 10x
1/2 x = 10
Multiply both sides by 2
x/2 × 2 = 10×2
x×1 =20
x = 20
Hence Rui will reach his lowest altitude after 20seconds of diving
A number cube is rolled 600
times. Predict how many times a 2 or a 6 would be rolled.
The number 2 or 6 would be rolled 200 times.
Important information:
A number cube is rolled 600 times.Expected value:Number cube has six numbers 1, 2, 3, 4, 5, 6. So, the probability of getting either 2 or a 6 is:
[tex]P(2\cup 6)=\dfrac{2}{6}[/tex]
[tex]P(2\cup 6)=\dfrac{1}{3}[/tex]
The expected value of getting a 2 or a 6 would be rolled is:
[tex]E(2\cup 6)=600\times P[/tex]
[tex]E(2\cup 6)=600\times \dfrac{1}{3}[/tex]
[tex]E(2\cup 6)=200[/tex]
Therefore, the number 2 or 6 would be rolled 200 times.

A regular polygon is a shape with sides that all have equal lengths and angles that all have equal measures. If each exterior angle of a certain regular polygon measures 24o, what is the interior angle sum for this polygon?
Answer:
2340
Step-by-step explanation:
360/24 =15whichis number of sides
180(15-2)=2340
Answer:
Exterior Angle of 24º means Interior Angle of 156º
Interior Angle = 180 -Exterior Angle
Number of sides = 360 / (180 - ONE Interior Angle)
Number of sides = 360 / (180 - 156º)
Number of sides = 360 / 24
Number of Sides = 15

Answer:
QR ≈ 16.2 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan62° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{QR}{RP}[/tex] = [tex]\frac{QR}{8.6}[/tex] ( multiply both sides by 8.6 )
8.6 × tan62° = QR , then
QR ≈ 16.2 ft ( to the nearest tenth )

Answer:
x = 25; ∠3 = ∠6 = 60°
Step-by-step explanation:
Angles 3 and 6 are alternate interior angles, so are congruent.
2x +10 = 3x -15
25 = x . . . . . . . . . . . add 15-2x
2x +10 = 2(25) +10 = 60
The measures of angles 3 and 6 are 60°.

The system has three real solutions.
The system has one real solution.
The system has two real solutions.
The system has no real solutions.
Answer:
The system has no real solutions.

the system is : y=-3x² - 4x +7.....(*)
3x + 2y = 18.....(**)
use (*) put tue value for y in (**) : 3x+2(-3x² - 4x +7) = 18
3x+-6x² -8x +14 = 18
