Answer:
[tex]y = 18*4^x[/tex]
Step-by-step explanation:
We want an exponential equation in the following format:
[tex]y = ab^x[/tex]
Point (0,18):
This means that when [tex]x = 0, y = 0[/tex]. So
[tex]y = ab^x[/tex]
[tex]18 = ab^0[/tex]
[tex]a = 18[/tex]
So
[tex]y = 18b^x[/tex]
Point (2,288):
This means that when [tex]x = 2, y = 288[/tex]. So
[tex]y = 18b^x[/tex]
[tex]18b^2 = 288[/tex]
[tex]b^2 = \frac{288}{18}[/tex]
[tex]b^2 = 16[/tex]
[tex]b = 4[/tex].
So
[tex]y = 18*4^x[/tex]

All skelts have an odd number of sides. (false, one have 6 sides, which is an even number)
Suppose that a population parameter is 0.7 and many samples are taken from the population. If the size of each sample is 100, what is the standard error of the distribution of sample proportions?
Answer: .046
Step-by-step explanation: I just had this question
The statement : "for a sample size of n = 26 and a population parameter of p = 0.6, a normal curve can be used to approximate the sampling distribution" is true.
What is normal curve?Normal curve is used to represent the class shapes in the statistical probability. Mathematically, we can describe the normal curve as -
[tex]$f(x)= {\frac{1}{\sigma\sqrt{2\pi}}}e^{- {\frac {1}{2}} (\frac {x-\mu}{\sigma})^2}[/tex]
where -
f(x) = probability density function
σ = standard deviation
μ = mean
Given is that for a sample size of n = 26 and a population parameter of
p = 0.6, a normal curve can be used to approximate the sampling
distribution.
It is asked to identify whether the given statement regarding the normal curve is true or false. The given statement is - "for a sample size of n = 26 and a population parameter of p = 0.6, a normal curve can be used to approximate the sampling distribution". The given statement is true.
Therefore, the statement : "for a sample size of n = 26 and a population parameter of p = 0.6, a normal curve can be used to approximate the sampling distribution" is true.

What is the multiplicative rate of change of the function???
The multiplicative rate of change of the function will be 2/3. Then the correct option is B.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as,
y = a(b)ˣ
At (1, 6), then we have
6 = a(b)¹
6 = ab ...1
At (2, 4), then we have
4 = a(b)²
4 = ab ...2
Divide equation 2 by equation 1, then we have
ab² / ab = 4 / 6
b = 2 / 3
The multiplicative rate of change of the function will be 2/3. Then the correct option is B.

Kelly works in a grocery store stocking shelves. The graph below shows the money Kelly earns stocking shelves.
Write an equation to represent the money Kelly earns in relationship to the hours she works. Let m represent the money she earns, and let h represent the number of hours she works.
Answer: m=1/8h
Step-by-step explanation:
When writing a linear equation, the slope is always rise over run. When it rises (goes up) 1, it runs (goes to the side 8. So the slope is 1/8. There is no y intercept because the line passes through (0, 0). The equation is m= because the amount of money earned equals 1/8h.

what is the x intercept of the graph of y=4x-36
Answer:
36
Step-by-step explanation:
My explanation to this is that if you look at the problem it will show you 36.
Answer:
9
Step-by-step explanation:
To find the x-intercept, set y = 0
0 = 4x-36
Add 36 to both sides:
0+36 = 4x-36+36
36 = 4x
Divide by 4 on both sides:
36/4 = 4x/4
9 = x
The x-intercept is 9

Answer:
x = 10
MB = 16
CM = 16
CB = 32
Step-by-step explanation:
Since it's the mispoint
2x - 4 = x + 6
Subtract x from both sides
x - 4 = 6
Add 4 to both sides
x = 10
MB = 2x - 4
MB = 20 - 4
MB = 16
CM = x + 6
CM = 16
CB = 16 + 16
CB = 32
The product of a number and 16 is equal to the sum of the number and 14
Step-by-step explanation:
let number be x
16x = 14 + x
16x - x = 14
15x = 14
x = 14 ÷ 15
x = 0.9
8 Mangoes = 30 bananas
5 banana= 2 oranges
15 oranges=? mangoes
Answer:
it would only be 8, unless you need to go down to the decimal point then it would be 8.25
Step-by-step explanation:
it would be 8 because if you need to find how many bananas you have, to do this you would divide 15 by 2 and get 7.5 then you multiply those by 5 to get the number of bananas which would be 37.5, and then if 8 mangos = 30 bananas you only have 8 mangos.

What is the area of a circle with a radius of 13 millimeters? (use 3.14 for pi)
===============================================
Work Shown:
A = pi*r^2
A = 3.14*13^2
A = 3.14*169
A = 530.66 square millimeters
We can abbreviate "square millimeters" into "square mm" or into "mm^2".
This value is approximate because pi = 3.14 is approximate.

45°
&2
86°
Enter
Answer:
[tex] \displaystyle \angle2 = {49}^{ \circ} [/tex]
Step-by-step explanation:
remember that,
if a side of a triangle is extended then exterior angle so formed equal to the sum of the two opposite interior angles
thus our equation is
[tex] \displaystyle \angle2 + {86}^{ \circ} = {135}^{ \circ} [/tex]
cancel out 86° from both sides:
[tex] \displaystyle \angle2 = {49}^{ \circ} [/tex]
hence,
the measure of the missing angle is 49°
Answer:
Solution given'
<2+45+86=180°[sum of interior angle of a triangle]
<2=180-131
<2=49°
