The population size after 6 years and after 8 years are 147 and 169 population respectively
<h3>Exponential functions</h3>
The standard exponential function is expressed as y = ab^x
where
a is the base
x is the exponent
Given the function that represents the population size P (t) of the species as shown;

For the population size after 6 years

For the population after 8 years

Hence the population size after 6 years and after 8 years are 147 and 169 population respectively

Answer:
x= -674
Step-by-step explanation:
Solve for x and check: x + 5 = 3
Solution
Solve for x and check: - 3x = 12
Dividing each side by -3, we obtain
Another way of solving the equation
3x - 4 = 7x + 8
would be to first subtract 3x from both sides obtaining
-4 = 4x + 8,
then subtract 8 from both sides and get
-12 = 4x.
Now divide both sides by 4 obtaining
- 3 = x or x = - 3
Solve for c: 3(x + c) - 4y = 2x - 5c
First remove parentheses.
Remember, abx is the same as 1abx.
We divide by the coefficient of x, which in this case is ab.
Answer:
The value of P-value is 0.0472.
Step-by-step explanation:
We are given that you take a simple random sample of 12 apartments in town A and calculate the average price of these apartments. You repeat this for 15 apartments in town B.
Let
= <u><em>true average price of apartments in town A</em></u>
= <u><em>true average price of apartments in town B</em></u>
So, Null Hypothesis,
:
Alternate Hypothesis,
:
The test statistics that have been used here is <u>two-sample t-test statistics</u>, i.e;
The test statistics given to us is 2.1
Now, the P-value of the test statistics is given by the following formula;
P-value = P(
> 2.1)
= P(
> 2.1) = 0.0236
In two-tailed test, P-value is calculated as = 2
0.0236 = <u>0.0472</u>
Hence, the value of the p-value is 0.0472.
Answer:
66+12x

6+60+12x
66+12x
White paint = 2/3 * 17 = 11.33 liters , 11.33*2.10 = $23.8
blue paint = 1/3 * 17 = 5.66 liters, 5.66*1.50 = $8.5
Total cost = 23.8+8.5 = 32.30 euros
