Answer: Joe has initial amount of $12 ( when he played no game).
Step-by-step explanation:
Given: Joe took $12 to the arcade. Each game cost $.50 to play.
This situation can be modeled with the equation
Here,
Money Joe has remaining is repreesnted by 'y', and the number of games he plays is represented by 'x'.
Since y-intercept gives the initial value of the function when x=0.
To find y-intercept , we out x=0 in funtion , we get
So , y-intercept of this function is at y=12.
Meaning of the y-intercept in the terms of this problem :
Joe has initial amount of $12 ( when he played no game).

Answer:
The value of P-value is 0.0472.
Step-by-step explanation:
We are given that you take a simple random sample of 12 apartments in town A and calculate the average price of these apartments. You repeat this for 15 apartments in town B.
Let = <u><em>true average price of apartments in town A</em></u>
= <u><em>true average price of apartments in town B</em></u>
So, Null Hypothesis, :
Alternate Hypothesis, :
The test statistics that have been used here is <u>two-sample t-test statistics</u>, i.e;
The test statistics given to us is 2.1
Now, the P-value of the test statistics is given by the following formula;
P-value = P( > 2.1)
= P( > 2.1) = 0.0236
In two-tailed test, P-value is calculated as = 2 0.0236 = <u>0.0472</u>
Hence, the value of the p-value is 0.0472.
That's a second-degree expression in 'x'. It represents a number,
but the number it represents completely depends on the value of 'x'.
And if the value of 'x' ever changes, then the value of the whole
expression instantly changes.
The expression is also the product of (x + 5) and (x - 9) .
Answer:
A. 50
Step-by-step explanation:
Sum of interior angles of a triangle is always =180 °
Since this is a right triangle, therefore we know that one angle of the triangle measures 90°
Therefor sum of other two angles has to be =
One angle measures = 40°
Therefore the missing angle
