A team of biologists captured and tagged 65 deer in a forest. Two weeks later, the
biologists captured a sample of 30 deer from the same forest and found that 5 of
them were tagged. Which proportion could be used to estimate the number of deer in
the forest?
Answer:
1/6x= 65
Step-by-step explanation:
so we can assume that 5/10= 1/6 of the deer were tagged
lets call the total number of dear x
so 1/6x= 65
x= 380
The proportion that can be used to estimate the number of deer in the forest is 5/30 = 65/390
To estimate the number of deer in the forest, we can set up a proportion using the tagged deer in the sample as a representative of the entire population.
Let's denote the number of deer in the forest as 'x'.
We know that 65 deer were tagged out of the total population. In the sample of 30 deer, 5 were tagged.
Therefore, we can set up the following proportion:
Tagged deer in sample / Total deer in sample = Tagged deer in population / Total deer in population
5 / 30 = 65 / x
Now we can cross-multiply to solve for x:
5x = 65 * 30
5x = 1950
Dividing both sides by 5:
x = 1950 / 5
x = 390
Therefore, the proportion that can be used to estimate the number of deer in the forest is 5/30 = 65/390

A store manager buys binoculars for $45 each. He marks up the cost by 40% to get the store price. Then the store has a sale and the store price is reduced by 10%. What is the sale price of the binoculars?
Answer:
$56.70
Step-by-step explanation:
The cost plus markup is found by multiplying $45 by 1.40: $63.
With the 10% price reduction, the sale price is 0.90($63) = $56.70.
Regarding 1.40: the '1' results in the full price to the manager plus the '0.40' markup.

there are 18 black socks and 12 Navy socks in your drawer the room is dark and you cannot turn on the light what is the least number of socks that you have to take out of the drawer to be certain that you have a pair of the same color
Answer:
3/5
Step-by-step explanation:
To have the best chance of pulling a pair with the same color you should try to get a pair of black socks. There is a 3/5 chance of pulling a black sock so this means for every 5 socks you pull you get 3 black socks or 2 navy socks. Either way you will get a pair of socks with the same color. (Double check to make sure I'm correct)
The least number of socks that you have to take out of the drawer to be certain that you have a pair of the same color is 5 and the color is black and this can be determined by using the given data.
Given :
There are 18 black socks and 12 Navy socks in your drawer the room is dark and you cannot turn on the light.
The following steps can be used in order to determine the least number of socks that you have to take out of the drawer:
Step 1 - According to the given data, the total number of black socks is 18 and the total number of Navy socks is 12.
Step 2 - The probability that the socks come out is black socks is given below:
[tex]\rm P_b = \dfrac{18}{12+18}[/tex]
[tex]\rm P_b = \dfrac{18}{30}=\dfrac{3}{5}[/tex]
Step 3 - The probability that the socks come out is navy socks is given below:
[tex]\rm P_n = \dfrac{12}{12+18}[/tex]
[tex]\rm P_n=\dfrac{12}{30}=\dfrac{2}{5}[/tex]
Step 4 - Compare both the probability.
[tex]\rm P_b>P_n[/tex]
So, the least number of socks that you have to take out of the drawer to be certain that you have a pair of the same color is 5 and the color is black.

30.3°
Answer:
20.3
Step-by-step explanation:
Answer:
Step-by-step explanation:
u=6i-j
v=7i-4j
u.v=|6i-j||7i-4j| cos α,where α is the angle between u & v.
(6i-j).(7i-4j)=√(6²+(-1)²)√(7²+(-4)²) cos α
(6)(7)+(-1)(-4)=√37√65 cos α
42+4=√37√65 cos α
[tex]\cos \alpha =\frac{46}{\sqrt{37} \sqrt{65} } \\\alpha =\cos^{-1}\frac{46}{\sqrt{37} \sqrt{65} } \approx 20.28^\circ \approx 20.3^\circ[/tex]

Answer:
1. T = -5 2. X = 12 3. X = 60
Step-by-step explanation:
5t + 17 = 4(t + 3)
1. Distribute 4
5t + 17 = 4t + 12
2. Isolate the variable
t + 17 = 12
t = -5
1/2x + 1/3x = 10
1. Remove fractions by multiplying the equation by 6
3x + 2x = 60
2. Combine like terms
5x = 60
3. Divide by coefficient
x = 12
1/4x + 2/5x = 39
1. Remove fractions by multiplying by 20
5x + 8x = 780
2. Combine like terms
13x = 780
3. Divide by coefficient
x = 60
