1. The answer would be true
<span>Part A: Does the table represent y as a function of x? Justify your answer.
The function of x is "</span><span>fifth powers of x" which can be write as
</span>f(x)= x^5
To determine whether the y represent f(x), you can try to put a value of x into the function, then compare the value of f(x) with y.
For x=1 and y=1
f(x)= x^5
f(1)= 1^5
f(1)= 1 = y
For x=2 and y=32
f(x)= x^5
f(2)= 2^5
f(2)= 32 = y
2.
<span>What is the value of f(4) and what does f(4) represent?
The f(4) means putting 4 as the x value. In the function, the f(x) represent price </span>for renting a bowling lane and the variable x represent the number of hours. Then f(4) represent the price for renting a bowling lane for 4 hours.
The value would be:
<span>f(x) = 2x + 12
</span><span>f(4) = 2(4) + 12
f(4)= 8+12= $20</span>
Answer:
25% or more
Step-by-step explanation:
t1 = d1/v1 , t2 = d2/v2.
d1 = d2 , and v1 = 0.8 v2
t1 / t2 = d1/d2 x v2/v1 = v2/v1 ( as d1 = d2 )
t1/t2 = v2 / v1 = v2/0.8 v2 = 1/0.8 = 1.25
Answer:
12
Step-by-step explanation: 12:3=4, 4 x 2= 8
If we plot the data on the graph, we can see that the
data is skewed to the right (positive skew) and there is an outlier. In skewed
data and presence of outlier, the median is most commonly used measure of
central tendency. This is because a positive skew would result in a positive
bias to the mean. Meaning that it would be a lot larger than the median and not
really representing the actual central tendency. The median however is less
affected by the skew and outliers.
Answer: Median, because the data are skewed and there is
an outlier

Y= -3/5x - 2 Add -3/5x to both sides
3/5x +y= -2 Multiply both sides by 5 because 5 is the denominator.
By multiplying by 5 you can cancel out and make it a real number.
5(3/5x +y) = -2(5)
3x + 5y= -10 is the answer.
