Answer:
El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.
Step-by-step explanation:
Sabes que el número N(t) de animales vivos después de t años se predice mediante N(t) = 100*[tex]0.9^{t}[/tex]
Para estimar el número de animales vivos después de, por ejemplo, 1 año debes simplemente reemplazar el tiempo t por el tiempo correspondiente, en este caso 1 año:
N(1) = 100*[tex]0.9^{1}[/tex]
Resolviendo:
N(1) = 100*[tex]0.9^{1}[/tex]= 100*0.9= 90
De manera similar, podes estimar el número de animales vivos después de 5 y 10 años. Esto es, reemplazas t por 5 años:
N(5) = 100*[tex]0.9^{5}[/tex]= 100*0.59049= 59.049≅ 60
y t por 10 años:
N(10) = 100*[tex]0.9^{10}[/tex]= 100*0.3487= 34.86 ≅ 35
El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.

Neil has 3 partially full cans of white paint.They contain 1/3 gallon, 1/5, gallon, and 1/2, gallons of paint About how much paint dose Neil have in all?
Answer:
1 and 1/30 gallons
Step-by-step explanation:
First, convert all the fractions to a common denominator. I'm choosing 30.
1/3=10/30 1/5=6/30 1/2=15/30
Now, you can add them together to get 31/30, so a little more than a gallon
James is putting a brick border around his circlar Pool. The bricks are 1 foot in length. How many brick does need to buy to build the border. Use 3.14 for π
Answer:
Step-by-step explanation:
Using the formuka for calculating equation of a circumference
C = 2πr
r is the radius
Given
r = 1foot
C = 2π{1)
C = 2(3.14)
C = 6.28foot
Hence he needs about 6 bricks to build the border

Evaluating the function, f(x) = –2x² – 3x + 5 for x = -3, we would have: f(-3) = -4. (option B).
How do you Evaluate a Function?To evaluate a function, plug in the given value of the input (x) and simplify.
Thus:
f(x) = –2x² – 3x + 5
Substitute x = -3 into the function
f(-3) = –2(-3)² – 3(-3) + 5
f(-3) = -2(9) + 9 + 5
f(-3) = -4
Therefore, evaluating the function, f(x) = –2x² – 3x + 5 for x = -3, we would have: f(-3) = -4. (option B).

Question 2(Multiple Choice Worth 5 points) (04.01)The Boardman family walked two over five of a mile in two over seven of an hour. What is their unit rate in miles per hour?
Answer:
The unit rate in miles per hour = 1.4 miles/hr
Step-by-step explanation:
Given that:
Distance walked by Boardman family = Two over five of a mile = [tex]\frac{2}{5}\ miles[/tex]
Time taken by Boardman family = Two over seven of an hour = [tex]\frac{2}{7}\ hour[/tex]
To find:
The unit rate in the miles per hour = ?
Solution:
Formula for the rate or the speed can be given as:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Putting the values:
[tex]\Rightarrow \dfrac{\frac{2}5}{\frac{2}7}\\\Rightarrow \dfrac{7}{5}\\\Rightarrow \bold{1.4\ miles/hr}[/tex]
So, the unit rate in miles per hour = 1.4 miles/hr

Ms. Reyes buys three types of flowers. She buys 20 roses, 24 carnation, and 36 tulips. She plans to group the flowers into more than a bouquet. She wants to put the same number of each type of flower into each bouquet. What is the greatest number of bouquets Ms. Reyes can make?
Answer:
The greatest number of bouquets Ms. Reyes can make is 4 bouquets
Step-by-step explanation:
Ms. Reyes buys three types of flowers. She buys 20 roses, 24 carnation, and 36 tulips.
To find the greatest number of bouquets she can make, we solve using Greatest Common Factor method.
We find the factors of 20, 24 and 36
The factors of 20 are: 1, 2, 4, 5, 10, 20
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
Then the greatest common factor is 4.
Hence, the greatest number of bouquets Ms. Reyes can make is 4 bouquets

Zahra was given two data sets, one without an outlier and one with an outlier. Data without an outlier: 15, 19, 22, 26, 29 Data with an outlier: 15, 19, 22, 26, 29, 81 How is the median affected by the outlier? The outlier slightly affected the median. The outlier made the median much higher than all the other values. The outlier made the median much lower than all the other values. The median is the exact same number in both data sets.
Answer:
The outlier slightly affected the median.
Step-by-step explanation:
Given :
Data without an outlier: 15, 19, 22, 26, 29
Data with an outlier: 15, 19, 22, 26, 29, 81
The median :
Data without outlier :
0.5(n + 1) th term
n = 5
0.5(5 + 1) = 0.5(6) = 3rd term
3rd term = 22
Data with outlier :
0.5(n + 1) th term
n = 6
0.5(6 + 1) = 0.5(7) = 3.5th term
(3rd term + 4th term) /2
(22 + 26) / 2
48 / 2
= 24
From the result obtained ; The outlier slightly affected the median.
Answer:
A) The outlier slightly affected the median.
Step-by-step explanation:
Without the outlier, the median is 22, and with the outlier, the median is 24. So the outlier slightly affected the median.

The Jackson family borrowed $240,000 to purchase a house and, over thirty years they had to repay 250% of what they borrowed. What is the total amount of money the Jackson family paid for their loan? Brainly
Answer:
Step-by-step explanation:
Given
[tex]Loan = \$240,000[/tex]
[tex]Amount = 250\%[/tex]
Required
Determine the total amount
This is calculated by multiplying the loan amount by the percentage:
i.e.
[tex]Payment = Amount\% * Amount[/tex]
[tex]Payment = 250\% * \$200000[/tex]
[tex]Payment = \$500000[/tex]
Hence, the total payment is $500000
After releasing of radioactive material into.The atnosphere from.A nuclear.Powe plant in a country in 1988, the hay in that country was contaminayed by radioactive.Isotope remains, how long did the famers need to.Wait to use this hay
Answer:
the question is incomplete, so I looked for a similar one:
After the release of radioactive material into the atmosphere from a nuclear power plant, the hay was contaminated by iodine 131 ( half-life, 8 days). If it is all right to feed the hay to cows when 10% of the iodine 131 remains, how long did the farmers need to wait to use this hay?
iodine's half life (we are given x, we need to find b):
0.5A₀ = A₀eᵇˣ
x = 8 days
we eliminate A₀ from both sides
0.5 = eᵇ⁸
ln 0.5 = ln eᵇ⁸
-0.69315 = b8
b = -0.69315 / 8 = -0.08664
since the farmers need to wait until only 10% of the iodine remains (we already calculated b, now we need to find x):
0.1A₀ = A₀eᵇˣ
0.1 = eᵇˣ
ln 0.1 = bx
where b = -0.08664
x = ln 0.1 / -0.08664 = -2.302585 / -0.08664 = 26.58 days

Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
To find the slope of the graph, we use the expression below;
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
We pick two points; (-2, 1) and (4, 4)
x₁ = -2,
y₁ = 1
x₂ = 4
y₂ = 4
Now insert the parameters and solve;
Slope = [tex]\frac{4-1}{4- (-2)}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:
2^3 * 7 + 7^2
Step-by-step explanation:
1) divide 28 by 2 = 14
2) divide 14 by 2 = 7
3) this means that 2 * 2 * 7 = 28
4) you can then take those 2 twos and multiply them with the first 2 and make 2^3
5) the square root of 49 is 7 so that is just 7^2
6) plug in all these new values for the originals and you get the answer above
Answer:
first you gotta calculate 2 -28 +49
After getting the answer solve the expressions to see which one is equivalent to 2-28 +49 (I think)
