Suppose Mike’s exponential model is the best fit for a sample of two-variable data collected from a population of 30 voters. His model has the following values for a and b. a = 4039.22 b = 0.1719 How does Mike project Y from a value of X in the voter population? Mike uses the greatest value of a or b Mike projects y using the model y = 4039.22 x + 0.1719 Mike multiplies a and b Mike uses the values of a and b in the equation
5x + 3y = 9
4x - 2y = -6
Write as a ordered pair
Answer:
(0,3)
Step-by-step explanation:
Solving Simultaneously, 4(5x + 3y = 9)
-5(4x - 2y = -6)
then, 20x + 12y = 36
-20x + 10y = 30
adding the two equations we get,
22y=66, hence y= 3
then substituting y in one of the equations
5x + 3(3) = 9 hence x = 0

Which statement correctly compares the two functions shown?
Function 1 has a smaller y-intercept and greater slope than Function 2.
Function 1 has a smaller y-intercept and the same slope as Function 2
Function 1 has the same y-intercept and greater slope than Function 2.
Function 1 has the same y-intercept and slope as Function 2.
Answer:
C.
Step-by-step explanation:
For Function 2
x=1 y=8
x=2 y=11
8=m+b
11=2m+b
11-8=2m-m
m=3
8=3+b
b=5
y=3x+5
Function 1
y=4x+5
Function 2
y=3x+5
....................
Function 1 has the same y-intercept and greater slope than Function 2.
These expressions below represent four numbers. The value of the median of these expressions is 12.
x 2x 6x 11x
Work out the value of the mean of these expressions
Answer:
The mean is 15
Explanation:
The x value that would get a median of 12 is three, which when taken the mean of the numbers when x is three, you get 15
The mean value of the given expressions with a median of 12 is: 7.
What is the Mean and Median of a Data Set?Mean = average of the data set.
Median = center value or average of the center values.
Given that the median for x, 2x, 6x, 11x is 12, therefore:
12 = (6x + 11x)/2
2(12) = 17x
24 = 17x
x ≈ 1.4
Mean = (x + 2x + 6x + 11x)/4 = 20x/4
Plug in the value of x
Mean = 20(1.4)/4
Mean = 7

A. $0.32
B. $0.54
C. $0.89
D. $2.88
If Alfonso has a $10 bill. At the grocery store, he buys a loaf of whole wheat bread for $1.99 and 9 bananas. He gets $5.13 in change. The price of one banana is $0.32
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Alfonso has a $10 bill.
At the grocery store, he buys a loaf of whole wheat bread for $1.99 and 9 bananas
So $10.00-$1.99= $8.01
We need to find price of one banana.
He gets $5.13 in change.
$8.01-$5.13=$2.88
He used $2.88 to buy nine bananas
The price of each banana we will calculate by dividing $2.88 by 9.
$2.88/9=$0.32
The price of each banana is $0.32, Option A is correct.

Which value of b makes the equation b4=12 true? A.48 B.16 C.8 D.3
The value of b that makes the equation b * 4 = 12 true is b = 3. Thus, the correct answer is option (D).
Let's apply each option and see which value of b makes the equation b * 4 = 12 true:
A) b = 48
48 * 4 = 192 (not equal to 12)
B) b = 16
16 * 4 = 64 (not equal to 12)
C) b = 8
8 * 4 = 32 (not equal to 12)
D) b = 3
3 * 4 = 12 (equal to 12)
Therefore, the value of b that makes the equation b * 4 = 12 true is b = 3.

The pattern rule for a sequence is "Start at 10, double the number before this one,
and subtract 1." Write the first five numbers in the sequence.
The first five numbers in the sequence are 10, 19, 37, 73 and 145.
What are sequences?Sequences are a list of elements (numbers, most of the time) in which the order of elements matters.
Given that, The pattern rule for a sequence is "Start at 10, double the number before this one, and subtract 1."
Forming the equation according to question, we get,
(2n-1)
The first number is 10
2nd = 10x2-1 = 19
