Answer: [tex]\dfrac{25}{56}[/tex]
Step-by-step explanation:
Given: P(dot sent) = [tex]\dfrac37[/tex]
and P(dash sent) = [tex]\dfrac47[/tex]
P(dot received) = P(dot received ∩ dot sent)
+ P(dot received ∩ dash sent)
= P(dot received | dot sent)P(dot sent) + P(dash received | dash sent)P(dash sent) [By conditional probability formula]
[tex]=\dfrac78\times\dfrac37+\dfrac18\times\dfrac47=\dfrac{25}{56}[/tex]
Hence, the probability that the received symbol is a dot = [tex]\dfrac{25}{56}[/tex]

find the coordinates of point S On QR such that the ratio of QS to SR is 1:3 Q(2,5) R(-2,-3)
Answer:
slope or what y2-y1/x2-x1 use the formula
The coordinate of point S such that QS to SR is 1:3 will be (1,3).
What are coordinates?A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).
Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.
For example (5,3) here 5 will be for the x and 3 will be for the y.
Another example is (9,0) here 9 is for x and 0 is for y.
Given the coordinate Q(2,5) and R(-2,-3)
The intersection ratio is 1 over 3
The coordinate of point S is given by
x = [1(-2) + 3(2)]/(1+3) ⇒ x = 1
y = [1(-3) + 3(5)]/(1+3) ⇒ y = 3
Hence "The coordinate of point S such that QS to SR is 1:3 will be (1,3)".

The altitude of Death Valley California is 282 ft below sea level of hot air balloon is launched From The Bottom Of Death Valley and Rises at a rate of 10 ft per second after 12 seconds balloon Captain lower the balloon 15 ft what is the altitude of a hot air balloon after being lowered
Answer:
177 ft below sea level.
Step-by-step explanation:
Initial altitude of the hot air balloon = 282 below sea level
Rate of rise of balloon = 10 ft / second
Time = 12 seconds
Total rise in 12 seconds = Rate of rise of balloon [tex]\times[/tex] Time
[tex]\Rightarrow 10 \times 12[/tex] = 120 ft
Now, we will have to subtract to find the new altitude.
New altitude = 282 - 120 = 162 ft
Now, it is given that balloon Captain lowers the balloon 15 ft.
To find the final altitude, we will have to add it to the previous altitude.
Therefore, the final altitude = 162 + 15 = 177 ft below sea level

Which statement is true about parallel lines?
A. They intersect and are coplanar.
B. They intersect, but are not coplanar.
C. They do not intersect, but are coplanar.
D. They do not intersect and are not coplanar.
Answer:
C( They do not intersect, but are coplanar
Step-by-step explanation:
Parallel lines are coplanar (they lie in the same plane) and never intersect.
The statement that is true about parallel lines is that they do not intersect, but are coplanar: Option C is correct.
Lines are 2-dimensional figures that are used to connect two on more points in a xy-plane.
For two lines to be parallel, this means that the lines;
cannot meet each other i.e. they can not intersectThey can lie on the same plane i.e they can be coplanarHence we can conclude that the statement that is true about parallel lines is that they do not intersect, but are coplanar.

Mia and her children went into a grocery store and where they sell apples for $2 each and mangos for $1.50 each. Mia has $20 to spend and must buy no less than 9 apples and mangos altogether. If Mia decided to buy 3 mangos, determine the maximum number of apples that she could buy.
The maximum number of apples that she can buy is 7.75.
We are given that:
- Apples cost $2 each.
- Mangos cost $1.50 each.
- Mia has $20 to spend.
- Mia must buy no less than 9 apples and mangos altogether.
- Mia decided to buy 3 mangos.
Now,
we can write the following system of equations:
[tex]$\begin{cases}2a + 1.5m \leq 20\\a + m \geq 9\\m = 3\end{cases}$[/tex]
Substituting $m = 3$ into the second equation, we get:
[tex]$a + 3 \geq 9 \Rightarrow a \geq 6$[/tex]
So, Mia must buy at least 6 apples.
To determine the maximum number of apples that she could buy, we can substitute m = 3 into the first equation and solve for a:
[tex]$2a + 1.5(3) \leq 20 \Rightarrow a \leq \frac{20 - 4.5}{2} = 7.75$[/tex]
Therefore, by equation answer will be 7.75.
