Step-by-step explanation:
Since the x-intercepts are -20 and 40, the line of symmetry is x = (-20 + 40)/2 = 10.
Now we have y = a(x - 10)² + 30, where a is an unknown constant. We can find a by using an x-intercept point.
=> (0) = a[(40) - 10]² + 30
=> 900a + 30 = 0, a = -1/30.
Hence the rule is y = -(x - 10)²/30 + 30.

A certain town never has two sunny days in a row. Each day is classified as being either sunny, cloudy (but dry), or rainy. If it is sunny one day, then it is equally likely to be either cloudy or rainy the next day. If it is rainy or cloudy one day, then there is one chance in two that it will be the same the next day, and if it changes then it is equally likely to be either of the other two possibilities. In the long run, what proportion of days are sunny
Answer:
the proportion of days that are Sunny is 0.2
Step-by-step explanation:
Given the data in the question;
Using markov chain;
3 states; Sunny(1), Cloudy(2) and Rainy(3)
Now, based on given conditions, the transition matrix can be obtained in the following way;
[tex]\left[\begin{array}{ccc}0&0.5&0.5\\0.25&0.5&0.25\\0.25&0.25&0.5\end{array}\right][/tex]
so let the proportion of sunny, cloudy and rainy days be S, C and R respectively.
such that, from column 1
S = 0.25C + 0.25R -------------let this be equation 1
from column 2
0.5C = 0.5S + 0.25R
divided through by 0.5
C = S + 0.5R ---------------------- let this be equation 2
now putting equation 2 into equation;
S = 0.25(S + 0.5R) + 0.25R
S = 0.25S + 0.125R + 0.25R
S - 0.25S = 0.375R
0.75S = 0.375R
S = 0.375R / 0.75
S = 0.5R
Therefore,
from equation 2; C = S + 0.5R
input S = 0.5R
C = 0.5R + 0.5R
C = R
Now, we know that, the sum of the three proportion should be equal to one;
so
S + C + R = 1
since C = R and S = 0.5R
we substitute
0.5R + R + R = 1
2.5R = 1
R = 1/2.5
R = 0.4
Hence, the proportion of days that are Rainy is 0.4
C = R
C = 0.4
Hence, the proportion of days that are Cloudy is 0.4
S = 0.5R
S = 0.5(0.4)
S = 0.2
Hence, the proportion of days that are Sunny is 0.2
Complete the following statement. The conditional probability of B given A can be found by _______. a. adding P(A) and P(B).b. assuming that event B has occurred, and then calculating the probability that event A will occur c. multiplying P(A) times P(B).d. assuming that event A has occurred, and then calculating the probability that event B will occur.
Answer: Assuming that event A has occurred
Step-by-step explanation:
The conditional probability of B given A can be found by assuming that event A has occurred, and then calculating the probability that event B will occur.
So, the correct answer is d.
The conditional probability of B given A, denoted as P(B|A), represents the probability of event B occurring given that event A has already occurred.
It is calculated by assuming that event A has occurred and then determining the probability of event B occurring under that assumption.
Mathematically, the conditional probability is calculated as:
P(B|A) = P(A and B) / P(A)
Where P(A and B) represents the probability of both events A and B occurring together, and P(A) represents the probability of event A occurring.
Therefore, option d. assumes that event A has occurred and then calculates the probability that event B will occur, which aligns with the definition of conditional probability.

DOWNLOAD PHOTOMATHhope this helps bro :)what is j+m, j times m and j divided by m
Answer:
j + m
jm
[tex]\frac{j}{m}[/tex]
Step-by-step explanation:
We have j and m and are asked to add, multiply and divide them both.
When it comes to adding, its all about like terms, if the terms are not alike meaning ending in the same variable they cannot be added.
Therefore j + m is equal to just j + m.
Now for multiplying, this is free rule, you can freely multiply any variable you want without reprecussion.
Therefore, j * m is equal to jm.
Now for dividing, this works like adding, where you can divide only if the terms are the same, since j and m are not the same. J divided by M is equal to [tex]\frac{j}{m}[/tex]
11) To approach a runway, a pilot must begin a 10° descent
starting from a height of 0.38 miles above the ground. At
the start of his approach, how far, d, is the plane from the
runway to the nearest tenth of a mile?
Answer:
the plane 2.2 miles away from the runway
Step-by-step explanation:
Given the data in the question and as illustrated in the image below;
from the image, using trigonometric ratio;
SOH CAH TOA
sin = opposite / hypotenuse
sin10° = 0.38 / x
xsin10° = 0.38
x = 0.38 / sin10°
x = 0.38 / 0.173648
x = 2.1883 miles ≈ 2.2 miles { the nearest tenth of a mile }
Therefore, the plane 2.2 miles away from the runway

a closed circular water tank in a subdivision is made up of concreate aluminum. its outer diameter is 8.4 m and its height is 12 m. if it is to be painted on the exterior, then how much total surface area is to be painted?
Answer:
122.7792 sq. m
Step-by-step explanation:
diameter= 8.4 m
therefore, radius = r = 4.2 m.......( as radius is 1/2 of diameter)
height = h= 12 m
only the exterior is to painted so the total surface area of the cylinder is taken,
total surface area of cylinder = 2π r( h+r)
=2* 3.14* 4.2*(12+4.2)
=122.7792 sq. m
