The value of p from the probability relation is where outcomes are mutually exclusive is [tex]p=\frac{4}{7}[/tex].
Given data:
To find the value of p, set up an equation using the given probabilities.
Let p be the probability of the first outcome.
The probability of the second outcome is p/2.
The probability of the third outcome is p/4.
Since these outcomes are mutually exclusive, their probabilities should sum up to 1.
So, [tex]p + \frac{p}{2} + \frac{p}{4} = 1[/tex]
On simplifying the equation:
[tex]\frac{(4p + 2p + p)}{4} = 1[/tex]
[tex]\frac{(7p)}{4} = 1[/tex]
Next, multiply both sides of the equation by 4 to isolate p:
7p = 4
Finally, divide both sides by 7 to solve for p:
[tex]p=\frac{4}{7}[/tex]
Therefore, the value of probability p is [tex]\frac{4}{7}[/tex].

By noon, the temperature in Juneau had risen by 16ºF.
What was the temperature there at noon?
Answer:
-17 degrees F
Step-by-step explanation:
Assuming that the temperature in the chart is the temperature before noon, all we need to do to find the temperature at noon is to add 16 degrees Fahrenheit to the table value (since "risen by 16 degrees F" means to increase by 16 degrees, aka to add 16 degrees).
So,
-33 + 16 = -17

The total number of boys and girls in a class are 45 students. If 65% of the children are girls, what percentage are boys?
Answer:
35%
Step-by-step explanation:
100% - 65% = 35%
Hope this helps!
Answer:
35%
Step-by-step explanation:
65% of 40 is 29.25
40-29.25=15.75
15.75 over 45 × 100 = 0.35
0.35 is also written as 35%

A 16-cup carton of ice cream costs $12.00. What is the price per pint?
9514 1404 393
Answer:
$1.50 per pint
Step-by-step explanation:
1 pint = 2 cups, so the cost of it is ...
x/(2 cups) = $12/(16 cups)
x = (2)($12/16) = $1.50 . . . . . . multiply by 2 cups
The price per pint is $1.50.

Answer:
independent variable/ variables
Step-by-step explanation:
The variable r is directly proportional to the square of t, and r = 144 when t = 72.
Write the equation that expresses the relationship between the variables. (Let k represent the variation constant.)
Using the given data, solve for the variation constant k.
Answer:
k=0.023
Step-by-step explanation:
[tex]r \alpha {t }^{2} \\ r = k {t}^{2} \\ 144 = k \times {72 }^{2} \\ k = \frac{144}{ {72 }^{2} } \\ k = 0.023 \\ the \: eqn \: is \: therefore \\ r = 0.023 \times {t}^{2} [/tex]
The equation that expresses the relationship between the variables is r=kt and the variation constant k=2.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".
Given that, the variable r is directly proportional to the square of t
Now, r∝t
r=kt
Here, r =144 when t =72
Thus, 144=k×72
k=2
Therefore, the equation that expresses the relationship between the variables is r=kt and the variation constant k=2.

arrange the following in ascending order
3/4 , -1/3 , 1/-2 , 3/10
Answer:
Ans: 1/-2 , -1/3 , 3/10 , 3/4
Step-by-step explanation:
The LCM of 2, 3, 4 and 10 is 60.
Let's make denominator equal,
→ 3/4 , -1/3 , 1/-2 , 3/10
→ 3×15/4×15 , -1×20/3×20 , -1×30/2×30 , 3×6/10×6
→ 45/60 , -20/60 , -30/60 , 18/60
Now we can order in ascending,
→ -30/60 , -20/60 , 18/60 , 45/60
→ 1/-2 , -1/3 , 3/10 , 3/4 {final answer}

Step-by-step explanation:
For a project in his Geometry class, Ryan uses a mirror on the ground to measure the height of his school’s football goalpost. He walks a distance of 12.15 meters from the goalpost, then places a mirror on flat on the ground, marked with an X at the center. He then walks 3.4 more meters past the mirror, so that when he turns around and looks down at the mirror, he can see the top of the goalpost clearly marked in the X. His partner measures the distance from his eyes to the ground to be 1.35 meters. How tall is the goalpost? Round your answer to the nearest hundredth of a meter.
9514 1404 393
Answer:
4.82 m
Step-by-step explanation:
The mirror reflects light at the same angle the light hits it, so the triangles formed by the line of sight, the ground, and the objects involved are similar. This means corresponding lengths are proportional.
height/mirror distance = T/12.15 = 1.35/3.4
Multiplying by 12.15, we find the top of the goalpost to have a height of ...
T = 12.15(1.35/3.4) ≈ 4.82 . . . meters
The goalpost is about 4.82 meters high.

Dry Clean USA has finished cleaning 30% of their 730 orders. How many orders do they still need to finish cleaning?
Step-by-step explanation:
100% = 730
1% = 100%/100 = 730/100 = 7.3
30% = 1% × 30 = 7.3 × 30 = 219
so, they finished 219 of their 730 orders.
that leaves 730 - 219 = 511 orders still to be finished.
