Answer:
30 minutes after biker left
Step-by-step explanation:
Given that :
Speed of hiker = 3 mph
Speed of biker = (3 +6) = 9 mph
Present Distance of hiker when the biker set out ;
Present Distance of hiker = speed * time = (3 * 1) = 3 miles
Time taken to catchup equals :
Present distance + (distance when biker set out) = bikers distance
Let time taken = x
(3 + (3 * x)) = (9 *x)
(3 + 3x) = 9x
3 + 3x = 9x
3 = 9x - 3x
3 = 6x
x = 3/6
x = 1/2 hours
x = 30 minutes

Lynn, Jude, and Anne were given the function f (x) = -3x^2 + 12 and they were asked to find (2). Lynn's answer was 48, Jude's answer v correct? Show Your Work
Answer:
(2) is equal to 48 because you substitute x for 2 in the equation. F(2)= -3(2)^2 +12= -3 times 2 is -6 then you square it to get 36 and add 12 to get 48

Answer:
1 divided by 20 is equal to 0.05.
Step-by-step explanation:
In this problem, we need to find 1 divided by 20 is equal to what.
1 should be in the numerator and 20 should be in the denominator.
[tex]\dfrac{1}{20}=\dfrac{1}{2}\times \dfrac{1}{10}\\\\=0.5\times 0.1\\\\=0.05[/tex]
Hence, 1 divided by 20 is equal to 0.05.

If the outlier is not included, what will happen to the range and the IQR of this data set?
A.
The range will stay the same, but the IQR will change.
B.
The range and the IQR will both stay the same.
C.
The IQR will stay the same, but the range will change.
D.
The range and the IQR will both change.
Answer:
D.
The range and the IQR will both change.
Step-by-step explanation:
PLATO
The correct answer is C. The IQR will stay the same, but the range will change.
How to calculate the IQR?To determine what will happen to the range and the IQR of this data set if the outlier is not included, we first need to identify the outlier.
One way to identify an outlier is to use the 1.5 x IQR rule. According to this rule, any data point that is more than 1.5 times the IQR away from the first or third quartile is considered an outlier.
Using this rule, we can calculate the IQR of the data set:
Arrange the data set in order from smallest to largest:
26 28 29 31 33 33 34 35 36 37 38 39 41 43 60
Find the median, Q₂, of the data set. In this case, Q₂ = 36.
Divide the data set into two halves: the lower half, which includes all values less than or equal to Q₂, and the upper half, which includes all values greater than or equal to Q₂:
Lower half: 26 28 29 31 33 33 34 35
Upper half: 36 37 38 39 41 43 60
Find the median, Q₁, of the lower half. In this case, Q₁= 30.
Find the median, Q₃, of the upper half. In this case, Q₃ = 41.
Calculate the IQR as the difference between Q₃ and Q₁: IQR = Q₃ - Q₁ = 11.
Multiply the IQR by 1.5: 1.5 x 11 = 16.5.
Add 16.5 to Q₃ and subtract 16.5 from Q₁ to get the upper and lower bounds for outliers:
Upper bound: Q₃ + 16.5 = 57.5
Lower bound: Q₁ - 16.5 = 13.5
Any value outside this range is considered an outlier.
In this data set, the value 60 is greater than the upper bound of 57.5, so it is an outlier.
Therefore, the correct answer is C. The IQR will stay the same, but the range will change.

Describe how the graph of y= x2 can be transformed to the graph of the given equation.
y = (x + 14)^2 (5 points)
Shift the graph of y = x2 down 14 units.
Shift the graph of y = x2 right 14 units.
Shift the graph of y = x2 left 14 units.
Shift the graph of y = x2 up 14 units.
Step-by-step explanation:
For y = x², y = 0 when x = 0.
For y = (x + 14)², y = 0 when x = -14.
Notice that the zero of the function has went from 0 to -14, or 14 units to the left.
The answer is "Shift the graph of y = x² left 14 units.".
Answer:
We conclude that the graph y = x² can be transformed into the graph of the given equation y = (x + 14)² by shifting the graph of y = x² left 14 units.
Step-by-step explanation:
Please check the attached graph.
The blue graph is representing the graph of y = x². The red graph is representing the graph of y = (x + 14)².If we carefully analyze the given graph which is attached below, it is clear that the given graph y = (x + 14)² is the transformed image of form f(x+b) of parent graph y = x².
In this graph, the function y = x² has been moved over 14 units to the left.
In other words,
f(x+2) = f(x+14)² means the function f(x) is shifted 14 units to the left.
Therefore, the graph y = x² can be transformed into the graph of the given equation y = (x + 14)² by shifting the graph of y = x² left 14 units.
