Part of the population of 6,750 elk at a wildlife preserve is infected with a parasite. A random sample of 50 elk shows that 11 of them are infected. How many elk are likely to be infected?

Based on the sample, there will likely be
infected elk in the wildlife preserve.

Answers

Answer 1

Answer:

1485 are likely to be infected.

Based on the sample, the probability of an elk being infected is 11/50.  Multiply this by the number of elk:

11/50(6750) = 1485.

Answer 2
i’m sorry if this is wrong but 1485

Each row contains the degree measures of two complementary angles. Complete the table. 

Answers

Answer:

10

65

36

90 - x

Step-by-step explanation:

90 - 80 = 10

90 - 25 = 65

90 - 54 = 36

90 - x

The other angles of these complementary pairs are 10°, 65°, 36°,        (90-x)°.

What is complementary angle?

Two angles are Complementary when they add up to 90 degrees (a Right Angle). The two angles can be part of the same or different figures.

For the given situation,

The table shows the degree measures of two complementary angles.

We need to find the other angle, which when added sums up 90°.

1.  One angle = 80°

Another angle = [tex]90-80[/tex]

⇒ [tex]10[/tex]°

2. One angle = 25°

Another angle = [tex]90-25[/tex]

⇒ [tex]65[/tex]°

3. One angle = 54°

Another angle = [tex]90-54[/tex]

⇒ [tex]36[/tex]°

4. One angle = x°

Another angle = [tex]90-x[/tex]

⇒ [tex](90-x)[/tex]°

Hence we can conclude that the other angles of these complementary pairs are 10°, 65°, 36°, (90-x)°.

Jason has already used 4/12 cans of paint while painting furniture. He is painting chairs which each use 10/6 cans of paint.

What is the total number cans used if he paints 19 chairs?
Your final answer should be a decimal.

Answers

Answer:

Based off of the calculations I did, I got 32 as the answer.

Step-by-step explanation:

Jason uses 10/6 of the paint for each chair he paints and according to the question, there are 19 chairs.

So we multiply these two numbers to get the amount of paint used after painting all 19 chairs.

10/6 * 19 = 31.666...

Then we add the previous amount Jason used for painting the furniture to the total amount of paint used after painting the 19 chairs.

31.666... + 4/12 = 32.

Thus, Jason used 32 cans of paint in total.

How do I write the fraction? Please help! I will give brainliest if 2 or more people answer :)

Answers

Answer:

The unit fraction is 1/3 and the whole number is 4 2/3 however its a mixed fraction so I'm not positive about it so you could make just use the 4 as a whole number.

Step-by-step explanation:

The unit fraction is written using a numerator of 1 and keeping the original denominator. So it would be 1/3. 3 goes into 14 4 times so you get the four there. however there is still 2/3 as 3 cannot go into 2. however if you would like to you can convert 2 divided by 3 into a decimal or 0.666666667.

Okay I don't know much you need explained so I'm gonna explain pretty much everything. Starting off, you need to follow the PEMDAS rules. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. So when solving you have to do it in this order.

A-(5)(0.6)*7=21

B-(4/5)(15)+8=(0.8)(15)+8=20

C-4(8+2)/2=4(10)/2=40/2=20

3 would be 53. Since the lines are parallel the angles will be the same

4 would be 47 because of outer exterior angles

Answer:

so basically these angles in the first pictures would be the same so it would equal 53 degrees and in the second picture they would also be the same so 47 degrees. is the angles dont look the same then youd subtract the number you have from 180 and that would equal up too the next angle but if your angles look like the same they will be.
