Historically, a given day at the beginning of March in upstate New York has a 18% chance of snow and a 12% chance of rain. If there is a 4% chance it will rain and snow on a day, then which of the following
represents the probability that a day in early March would have either rain or snow?
1.) .30
2.) .34
3.) .02
4.) .26
The Venn probability that a a day in early March would have either rain or snow is given by:
4.) .26
What is a Venn probability?In a Venn probability, two non-independent events are related with each other, as are their probabilities.
The "or probability" is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
In this problem, we have that the probabilities are given as follows:
[tex]P(A) = 0.18, P(B) = 0.12, P(A \cap B) = 0.04[/tex]
Hence:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
[tex]P(A \cup B) = 0.18 + 0.12 - 0.04[/tex]
[tex]P(A \cup B) = 0.26[/tex]
Which means that option 4 is correct.

Answer:
D) 7
Step-by-step explanation:
Tangents from the same external point are equal in length.
8x - 7 = 6x + 7Add 7 on both sides.
8x - 7 + 7 = 6x + 7 + 78x = 6x + 14Subtract 6x from both sides.
8x - 6x = 6x + 14 - 6x2x = 14x = 7The correct option is D.
Gary and Jessica exercise for a total of 18 hours per week. Jessica exercises 2 less than 3 times the hours that Gary exercises. How many hours per week does Gary exercise?
Enter your answer in the box.
Work Shown:
g = number of hours that Gary exercises
3g-2 = number of hours that Jessica exercises
(g) + (3g-2) = 18
4g-2 = 18
4g = 18+2
4g = 20
g = 20/4
g = 5
Gary exercises 5 hours per week.
Find the value of x that makes m ∥ n
Answer:
26
Step-by-step explanation:
When two lines are parallel, corresponding angles are equal.
Here,
m II n
5x + 13 and 143 are corresponding angles.
So,
5x + 13 = 143
Substract 13 on both sides,
5x = 143 - 13
5x = 130
Divide 5 on both sides,
x = 130 / 5
x = 26
which equation represents a linear function 2ry+y= 9 , y=12r-5 , 3y+r2+t=0, 4r+2(y-1)=0
The equation which represents a linear function for the variable y is y=12r-5. Option B is the correct option.
What is linear function?Linear function is the function in which the highest power of the unknown variable is one. Linear functions are used to model the real life problem in the mathematical expressions.
The linear function with dependent variable y and independent variable x can be written as,
y=mx+c
Here, m is the slope of the line represented by the function and c is the y intercept.
The equation given in the problem are,
2ry+y= 9
y=12r-5
3y+r2+t=0
4r+2(y-1)=0
The second option is similar to the standard linear function.
Hence, the equation which represents a linear function for the variable y is y=12r-5. Option B is the correct option.

Find the distance between the two points on the graph
Answer: The side highlighted is 6.3 units long
Step-by-step explanation:
You can use Pythagorean therum to solve this problem
a² + b² = c²
We already know the length of two of the sides, a and b. So we will replace those variables with the given values
2² + 6² = c²
And now we solve
2² + 6² = c²
4 + 36 = c²
c² = 40
