12, because the triangle is a 45,45,90 so sides a and b are both x, and the hypotenuse is x times the square root of 2. this means the hypotenuse is 6• the square root of 2• the square root of 2, the square root of 4 is 2. 6•2=12

Answer:
$2 per ride
Step-by-step explanation:
First determine how much she spent on rides
50 -26 = 24
She spent 24 dollars on rides
The divide by the number of rides
24/12 = 2
She spent 2 dollars per ride
Answer:
The diagram is attached below.
Step-by-step explanation:
A normal distribution mean 0 and standard deviation 1 is known as the standard normal distribution.
So, the readings on the thermometers (denoted by <em>Z</em>) follows N (0, 1).
It is provided that 2.7% of the thermometers are rejected because they have readings that are too high and 2.7% are rejected because they have readings that are too low.
This implies that:
The value of <em>z</em> associated to both these probabilities are:
<em>z</em> = 1.93.
That is,
*Use a <em>z</em>-table.
The diagram for the two readings that are cutoff values separating the rejected thermometers from the others is attached below.
Answer:
1. Yes
2. No
3. Yes
4. Yes
Step-by-step explanation:
#1
Yes, this is a function.
None of the x-values have more than one possible value for y. None of the x-values are repeated in this table.
#2
No, this is not a function.
For each and every value of x, there can only be one y. The x-value 13 has two possible values of y, 4 and -4. This is represented in the coordinates (13, 4) and (13, -4).
#3
Yes, this is a function.
The graph passes the vertical line test. If you were the pass a vertical line through the graph, it would only be touching the graph once, wherever the vertical line is placed.
#4
Yes, this is a function.
The equation given is a quadratic equation for an original parabola. All parabolas, when not inverse, are functions. This parabola opens down, so it will pass the vertical line test.
