The growth of a certain organism can be modeled by C(t)=10(1.029)^24t, where C(t) is the total number of cells after t hours. Which function is approximately equivalent to C(t)?
1. C(t) =240(0.083)^24t
2. C(t)=10(.083)^t
3. C(t)=10(1.986)^t
4. C(t)= 240(1.986)^t/24
Given:
The function is:
[tex]C(t)=10(1.029)^{24t}[/tex]
Where, C(t) is the total number of cells after t hours.
To find:
The function that is approximately equivalent to C(t).
Solution:
We have,
[tex]C(t)=10(1.029)^{24t}[/tex]
It can be rewritten as:
[tex]C(t)=10(1.029^{24})^{t}[/tex] [tex][\because (a^m)^n=a^{mn}][/tex]
[tex]C(t)\approx 10(1.986)^{t}[/tex] [tex][\because 1.029^{24}\approx 1.986][/tex]
The function [tex]C(t)=10(1.986)^{t}[/tex] is approximately equivalent to C(t).
Therefore, the correct option is 3.

Step-by-step explanation:
the easiest thing to do is to make the half squares which you have 4 into 2 whole squares then base times height
4x3=12
Answer:
26cm²
Step-by-step explanation:
Alrighty, let's go count squares:
On the top row, there's 4 (adding the halves together), on the second row there's 5, and on the bottom row there's also 4, so we add that all together to get:
4 + 5 + 4 = 13
But, because each square is 2 cm, we have to multiply:
13 x 2 = 26
So, the area of the shaded section is 26cm²

Yellow = 6
A. 3/5
B. 11/15
C. 2/5
D. 4/15
Answer:
Probability(Not red) = 11 / 15
Step-by-step explanation:
Given:
Outcomes;
Red = 8
Blue = 7
Green = 9
Yellow = 6
Find:
Probability(Not red)
Computation:
Probability(Not red) = 1 - Probability(red)
Probability(Not red) = 1 - [Number of red/ Total]
Probability(Not red) = 1 - [8/(8+7+9+6)]
Probability(Not red) = 1 - [8/30]
Probability(Not red) = 1 - [4/15]
By taking LCM
Probability(Not red) = (15 - 4) / 15
Probability(Not red) = 11 / 15

At a plant that manufactures bars of steel, a machine is used to cut the bars to specific lengths. The machine has a dial that sets the length of the bars to be cut. However, the dial is currently out of alignment and the plant manager is collecting data to assess the situation. The following table shows 8 trials at different dial settings along with the actual output length of the bars that were cut. All measurements are in millimeters.
(a) Use the following grid to construct a scatterplot in which dial setting is the explanatory variable and output length is the response variable. Based on your graph, does a linear model seem appropriate? Justify your answer.
(b) Use the data to construct a least-squares regression line to predict output length from dial setting.
(c) Assume that all conditions for inference are met. Indicate the hypotheses appropriate to test whether there is a linear relationship between output length and dial setting
(d) The test statistic for the appropriate test is t=9.018. Do the data provide convincing statistical evidence that there is a linear relationship between output length and dial setting?
Check Attached Photos. Sorry, it didn't let me submit it through text because of "inappropriate language," despite me not having any in my answer.
For the plant which manufactures bars of steel, the conclusions are as follows;
A. The scatter graph is shown.
B. The equation is y = 2.204 + 1.007x
C. Null hypotheses (H₀); β = 0
Alternative hypotheses (Hₐ); β ≠ 0
D. P-value (0.0001) is less than the significance level (α = 0.05).
What are null hypotheses and alternative hypotheses?In null hypotheses, there is no relationship between the two phenomenons under the assumption or it is not associated with the group. And in alternative hypotheses, there is a relationship between the two chosen unknowns.

A. The scatter plot is shown below.
Based on the scatter plot, a linear model seems appropriate to the model relationships between the dial setting of the machine and the output length of the steel bar.
The scatter plot shows the strong (r = 0.965), positive, linear association. There do not appear to be any outliners.
B. From the data to construct a least-squares regression line to predict output length from dial setting. Then
y = (a + bx)
Let x be the dial setting machine and y be the output length of steel bars (in mm).
y = 2.204 + 1.007 x
C. All conditions for inference are met. Indicate the hypotheses appropriate to test whether there is a linear relationship between output length and dial setting.
Let β be the true slope of the population regression line relating the dial setting of the machine (x) and the output length of the steel bars (y) at the manufacturing plant.
Null hypotheses (H₀) ; β = 0
Alternative hypotheses (Hₐ) ; β ≠ 0
Appropriate test = slope of regression line t-test.
D. The test statistic for the appropriate test is t = 9.018 with 6 degrees of freedom (7 - 1)
The normal curve is shown;
Using calculator command t-CDF, with the alternative hypotheses as β≠0, then P-value = 0.0001.
In probability notation;
P(b≥0.017) = P(t≥9.018) = 0.00005
P-value = (2) × (0.00005) = 0.0001
P-value = 0.0001
Assume α = 0.05
Since our P-value (0.0001) is less than the significance level (α = 0.05), we do not convince statistical evidence that there is a linear relationship between output length and dial setting.
As the dial setting (x) increases, the output length of the steel bar (y) increases as well.

Raul uses a credit card to take out a 3-year loan of $4500 at a rate of 15% to purchase
carpeting for his house. What will be the total amount he will repay for this loan?
Answer:
Amount of loan pay = $6.840 (Approx.)
Step-by-step explanation:
Given:
Amount of loan borrow = $4,500
Rate of interest = 15% = 0.15
Number of year = 3 year
Find:
Amount of loan pay
Computation:
Future value = Present value[1+r]ⁿ
Amount of loan pay = Amount of loan borrow[1+r]ⁿ
Amount of loan pay = 4,500[1+0.15]³
Amount of loan pay = 4,500[1.15]³
Amount of loan pay = 4,500[1.52]
Amount of loan pay = $6.840 (Approx.)

Malik bought a pack of erasers for $3.50 and some pencils for $0.99 each. He paid a total of $10.43. Which equation can be used to find the number of pencils Andrew bought? \
Answer:
The equation that can be used to find the number of pencils Andrew bought is:
x=(c-3.50)/0.99
Step-by-step explanation:
With the information provided, you can say that the total amount paid would be equal to the price of the pack of erasers plus the price per pencil for the number of pencils purchased, which can be expressed as:
c=3.50+0.99x, where:
c is the total cost
x is he number of pencils purchased
Now, you can solve for x in order to find the equation to calculate the number of pencils Andrew bought:
c-3.50=0.99x
x=(c-3.50)/0.99
According to this, the answer is that the equation that can be used to find the number of pencils Andrew bought is:
x=(c-3.50)/0.99

The equation is A = - ( 1/2) [ x - 12 ]
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A
Now , the value of A is A = - ( 1/2 )x + 6
Now , on factorizing the given expression , we get
On taking the common term as - ( 1/2 )
A = - ( 1/2 )x + 6
A = - ( 1/2 ) [x - ( 2 x 6 ) ]
On simplifying the equation , we get
A = - ( 1/2 ) [ x - 12 ]
Therefore , the value of A is A = - ( 1/2 ) [ x - 12 ]
Hence ,The equation is A = - ( 1/2) [ x - 12 ]
