Answer:
45158
Step-by-step explanation:
Since the colony grows at a rate of 12%, after 2 years there will be [tex]36000\cdot 1.12^2 = 45158.4[/tex] bacteria. Since you probably can't have part of a bacteria, you round to 45158.
Answer:
45158
Step-by-step explanation:
Since the colony grows at a rate of 12°/• , after 2 years there will be 36000.
1.12 power of 2 = 45158.4 bacteria.
And you cant have part of a bacteria
you round it to
45158.

After checking that conditions are met, you perform a significance test of 0:=1 versus :≠1 . You obtain a -value of 0.022.
Which of the following must be true?
A 95% confidence interval for will include the value 0.022.
A 99% confidence interval for will include the value 1.
None of these is necessarily true.
A 99% confidence interval for will include the value 0.022.
A 95% confidence interval for will include the value 1.
Answer:
A
Step-by-step explanation:
The true statement is
A 99% confidence interval for will include the value 1.
What is Confidence Interval?The range of values that we observe in our sample and for which we anticipate finding the value that accurately reflects the population is referred to as a confidence interval.
Given:
[tex]H_0: \mu = 1\\H_\alpha : \mu \neq 1[/tex]
P= 0.022
If the P- value is smaller than significance level, then the null hypothesis is rejected.
P< 0.05 - 5% Reject [tex]H_0[/tex]
P> 0.01 = 1% Fail to Reject [tex]H_0[/tex]
A 95% Confidence interval correspond with a significance test at the 5%
significance level.
A 99% Confidence interval correspond with a significance test at the 1%
significance level.
If the Significance test was Significant then the interval does not contain the value mentioned in the Hypothesis.
95% CI does not contains 1.
99% CI contains 1.

The perimeter of a square patio is (8x - 28). What is the length of one side?
Answer:
Length is 7, Permimeter is 28
Step-by-step explanation:
Perimeter=4×side
(8x-28)=4×x [let length be x]
8x-28=4x
8x-4x=28
4x=28
x=28÷4
x=7
Length = x = 7
Perimeter=(8x-28)
=(7×8)-28
=56-28
=28
A person whose eyes are 5 feet above the ground is standing on the runway of an airport 100 feet from the control tower. That person spots one of the air traffic controller at the window of the 132 foot tall tower. What is the angle of elevation to the nearest tenth of a degree?
Answer:
132-5 therefore the height from the eyes to the window is 127
100 feet away from the base of the tower
This forms two legs of a triangle
trying to find the degrees of this triangle.
Since its the two legs, you can use tanx which = to opposite side/adjacent side
Therefore, it is tanx = 127/100
But you are looking for x so arctan(1.27)
Must use calculator to find x.
Find the dimensions of the square or circle.
Complete question is;
Find the dimensions or, the square or circle. Area = 64π in²
Answer:
r = 8 inches
Step-by-step explanation:
We know that formula for area of a circle is; A = πr²
Where r is radius.
We are given Area as 64π in²
Thus;
πr² = 64π
π will cancel out to give;
r² = 64
r = √64
r = 8 inches
Lillian is going to invest in an account paying an interest rate of 5.7% compounded continuously. How much would Lillian need to invest, to the nearest ten dollars, for the value of the account to reach $7,600 in 7 years?
Answer:
The amount Lilian needs to invest is $5,160
Step-by-step explanation:
The parameters of the amount Lilian is going to invest in an account are;
The interest rate the account pays = 5.7%
The final amount the investment is expected to reach after the given time period = $7,600
The number of years of the investment = 7 years
The formula for compound interest is presented as follows;
[tex]A = P \cdot \left(1 + \dfrac{r}{n} \right)^{n\cdot t}[/tex]
Where;
A = The final amount = $7,600
P = The amount Lilian is to invest
r = The interest rate = 5.7% = 0.057
n = The number of times the interest is applied per time period = 1
t = The number of period that passes = 7 (years)
Therefore, we get;
[tex]7,600 = P \cdot \left(1 + 0.057 \right)^{7}[/tex]
∴ P = 7,600/(1 + 0.057)⁷ = 5,155.7123754
The amount Lilian needs to invest (rounded to the nearest ten dollars) for the value of the account to reach $7,600 in 7 years, P = $5,160

Find the mean absolute deviation (MAD) of the following data set. Round your answer to two decimal places.
3, 10, 6, 9, 7, 4
Answer:The mean absolute deviation (MAD) of the data set=2.17
Step-by-step explanation:
The mean absolute deviation (MAD) is also called the Mean deviation which tells us the variation and average distance of the mean and each data value in a data set.
Given the data set
3, 10, 6, 9, 7, 4
First find the mean
Mean =Sum of data set / Number of data set
=3+10+ 6 +9 + 7+ 4/ 6 =39/6 = 6.5
Next step is to subtract each data set from the mean and ignoring any negative sign accompanied to find the distance from the mean
Value distance from mean
3, 6.5 -3 3.5
10 6.5 -10 3.5
6, 6.5-6 0.5
9, 6.5 -9 2.5
7, 6.5 -7 0.5
4 6.5 -4 2. 5
Last step is to find the mean of the distances which is
Mean Deviation = (3.5+ 3.5+ 0.5+ 2.5+0.5+ 2.5) / 6
=13/6
=2.166666 rounded up to 2.17

Answer:
x = 5 or x = -5
Step-by-step explanation:
| a b |
| c d |
det = ad - bc
| x 4 |
| 3 x |
det = x * x - 4 * 3 = x^2 - 12
x^2 - 12 = 13
x^2 = 25
x^2 - 25 = 0
(x + 5)(x - 5) = 0

The Weston family spends a maximum of
$50.00 per month on entertainment. Write and
graph an inequality to represent this.
Answer:
y < 50x
Step-by-step explanation:
In order to graph this inequality, you first need to identify the important word(s) here to find the inequality sign; in this case, it would be "maximum of $50" a month. Since it's a maximum of $50 a month (or less than $50 a month), you can write it as:
Where m is months and c is total cost, c < 50m
If you need to graph this, you can write it as y < 50x. The cost is y since it's the output, and months is x since that's the input.
