Answer:
B. y = 10(2)^x
Step-by-step explanation:
y = ab^x
to find "b" divide the function at x = 3 by the function at x = 2
80 = ab^3
——————
40 = ab^2
This results in
2 = b
to find "a" plug pickany value of x
using x = 2
40 = a(2²)
40 = a(4)
a = 10
With a = 10 and b = 2 the exponential function y = ab^x is
y = 10(2)^x
Simplify the following exponential expressions:
1. 6y^3 x 5y^6
2. 8x^5 x 3x^2
3. 7m^4 x 3m x 5m^2
4. 10d^7 x 5d^0
Answer:
See below
Step-by-step explanation:
[tex]1. \: 6 {y}^{3} \times 5 {y}^{6} \\ = 6 \times 5 \times {y}^{3 + 6} \\ = 30 {y}^{9} \\ \\ 2. \: 8 {x}^{5} \times 3 {x}^{2} \\ = 8 \times 3 \times {x}^{5 + 2} \\ = 24 {x}^{7} \\ \\ 3. \: 7m^4 \times 3m \times 5m^2 \\ = 105 {m}^{4 + 1 + 2} \\ = 105 {m}^{7} \\ \\ 4. \: 10d^7 \times 5d^0 \\ = 10 \times 5 \times {d}^{7 + 0} \\ = 50 {d}^{7} [/tex]

The table below shows 10 data values:
125, 138, 132, 140, 136, 136, 126, 122, 135, 121
What values of minimum, Q1, median, Q3, and maximum should be used to make a box plot for this data?
A.) Minimum = 121, Q1 = 125, median = 133.5, Q3 = 136, maximum = 140
B.) Minimum = 121, Q1 =136, median = 133.5, Q3 = 125, maximum = 140
C.) Minimum = 125, Q1 = 130.25, median = 132.5, Q3 = 134.5, maximum = 138
D.) Minimum = 125, Q1 =134.5, median = 132.5, Q3 = 130.25, maximum = 138
Answer:
we have to put the numbers in order..
(121,122,125, 126,132),M,(135,136,136,138,140)
Step-by-step explanation:
minimum : (smallest number) = 121
Q1 : 125
Q2 (median) : (132 + 135) / 2 = 267/2 = 133.5
Q3 : 136
maximum : (largest number) = 140
I did this a long time ago so im not so sure
Answer:
Step-by-step explanation:
121 122 125 126 132 135 136 136 138 140
140 -121 =19 range
Min=121 max =140
Mean = 131.1
Median = 132+135=267/2=133.5

Answer:
[tex]m =13[/tex]
Step-by-step explanation:
Given
The attached dataset
Required
The mean absolute deviation
First, calculate the mean
[tex]\bar x = \frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{42+40+39+76+71+55+68+65}{8}[/tex]
[tex]\bar x = \frac{456}{8}[/tex]
[tex]\bar x = 57[/tex]
The mean absolute deviation (m) is:
[tex]m =\frac{1}{n} \sum|x - \bar x|[/tex]
So, we have:
[tex]m =\frac{1}{8} (|42 - 57| + |40 - 57| + |39 - 57| + |76 - 57| + |71 - 57| + |55 - 57| + |68 - 57| + |65 - 57|)[/tex]
Using a calculator, we have:
[tex]m =\frac{1}{8} (|-15| + |-17| + |-18| + |19| + |14| + |-2| + |11| + |8|)[/tex]
Remove absolute bracket
[tex]m =\frac{1}{8} (15 + 17 + 18 + 19 + 14 + 2 + 11 + 8)[/tex]
[tex]m =\frac{1}{8} *104[/tex]
[tex]m =13[/tex]
The mean absolute deviation is 13
You just opened a savings account and deposited $300 at 3% that u plan on withdrawing in 15 years. How much money will you have by then?
Answer:
$467.37
Step-by-step explanation:
Given data
Principal= $300
Rate= 3%
Time = 15 years
Applying the compound interest formula, we have
A=P(1+r)^t
A=300(1+0.03)^15
A=300(1.03)^15
A=300*1.5579
A=$467.37
Hence after 15years the balance will be $467.37
There are 20 pieces of candy in the box. If 15 of them are hard candies, what percentage of the candies in the box are hard candies?
Answer:percentage of the candies in the box that are hard candies=75%
Step-by-step explanation:
Total pieces of candy in the box=20
Number of candies that are hard =15
Percentage of candies that are hard =Number of candies that are hard / Total pieces of candy in the box x 100
= 15/20 x 100
=75%
What is the horizontal asymptote of j (x) = StartFraction 14 x cubed + 45 Over 2 x cubed + x + 9 EndFraction
Answer:
C. y=7
Step-by-step explanation:
guy above me was right
The horizontal asymptote of the given function [tex]f(x) = \dfrac{14x^{3} +45}{2x^{3}+x+9}[/tex] would be y = 7.
When do we get horizontal asymptote for a function?The line y = a is a horizontal asymptote if the function f(x) tends to 'a' from the upside of that line y = a, or from downside of that line.
The given function is
[tex]f(x) = \dfrac{14x^{3} +45}{2x^{3}+x+9}[/tex]
We need to determine the horizontal asymptote.
Horizontal asymptote;
From the given function, it is obvious that the denominator's degree is smaller than the numerator's degree.
Then, the horizontal asymptote is the y-axis.
Thus, the horizontal asymptote is y = 7.

Answer:
3rd option
Step-by-step explanation:
Consider the coordinates of A and A'

This represents a move of + 5 (0 → 5) units in the x- direction and a move of + 2 ( 0 → 2 ) units in the y- direction.
The figure is unchanged and must therefore be a translation with rule

Kate has a coin collection. She keeps 7 of the coins in a box which is only 5% of her entire collection.
Answer:
She has 140 coins in total.
Step-by-step explanation:
Since 7 coins is only 5% of the entire collection, 7 coins=5%. 100% is the total. So first you need to divide 100 by 5 which is 20 (100÷5=20). Next, you need to multiply 20 by 7 (20×7=140) to find out how much coins she has in total.
