Suppose that 2% of a population carries antibodies to a virus. For a research project, you need 30 people
with antibodies to the virus. How many people should you test so that the expected number of people with
the antibodies is 30?
Answer:
1500
Step-by-step explanation:
p = number of people who should be tested
.02p = 30
p = 30/.02
p = 1500

Which of the binomials below is a factor of this trinomial? 6X squared minus 7X -5
Answer:
C. 2x + 1
Step-by-step explanation:
Factorize 6x² - 7x - 5
6x² + 3x - 10x - 5
3x(2x + 1) - 5(2x + 1)
(3x - 5)(2x + 1)
Therefore, 2x + 1 is a binomial factor of 6x² - 7x - 5.

Is it possible to construct a triangle with side lengths of 35,120, and 125 units?
If the sum of the two smallest sides of a triangle are less than the third side, then the triangle cannot be constructed, since the sides would not be able to touch. However, since 35+120 is greater 125, this triangle can be formed
how many seconds are there in 8 minutes 12seconds
Answer:
1 minute has 60 seconds
therefore 8 minutes will have 60 × 8 seconds = 480 seconds
480 + 12 = 492
hence 8 minutes 12 seconds will have 492 seconds
Answer: 492 seconds
Step-by-step explanation:
1min = 60sec
therefore, 8min 12sec = [8 x 60] + 12
= 480 + 12
= 492 sec

The sum of two numbers is 90. The larger
number is 14 more than 3 times the smaller
number. Find the numbers.
First complete the equations below. where x stands for
the larger number and y stands for the smaller numben
x+y = [?]; x =[]+[ ]y
Enter
Answer:
x=71 and y=19
Step-by-step explanation:
First, we write out the first sentence as an equation. This is x+y=90. We also know that x=3y+14 because of the second sentence. Using this, we can substitute x in the first equation with what it is (3y+14). This makes the new equation 3y+14+y=90. Then, we collect like terms by adding the 'y's together - making 4y+14=90. We need to make the letters on one side and the numbers on the other. To do this, we subtract 14 from each side, making 4y=76. We want to find out what 'y' is by itself (not multiplied by four) so we divide each side by 4. This means that we have found out that y=19 because 76÷4=19. Now, it is time to solve x. Using our new knowledge that y=19, we can replace y in the equation x+y=90 with 19 so now we have x+19=90. This is the same as 90-19=x and we know that 90-19=71, so x must be 71. In conclusion, x=71 and y=19.
I hope this helps, have a great day!

Line DCE is parallel to line AB
a) Find the size of angle ABC
b) Find the size of angle DCA
c) Calculate the size of angle ACB
Answer:
Angle DCA = Angle CAB. (Alternate Interior Angle)
Angle DCA = 68°
Angles(DCA + ACB + BCE) = 180°. (Linear Pair)
Angle ACB + 68° + 33° = 180°
Angle ACB = 79°
Therefore,
Angle ABC = 33°. (Alternate Interior Angle)

2.
The mode of the data in dot plot 1 is less
than the mode of the data in dot plot 2.
Answer:
the answer is b. The mode of the data in dot plot 1 is less than the mode of the data in dot plot 2.
Step-by-step explanation:
In the dot plots 1 and 2, the statement which is true is that the mean of the data in dot plot 1 is greater than the mean of the data in data plot 2.
What is dot plot?The dot plot is the way oif representation of the data. This data is plooted in the form of points or dots over an x-y axis. The dot polt is also known as the strip plot.
Dot plot 1 is the top plot. The value of it are as,
2,3,4,5,5,6,6,6,6,7,7,7,8,8,9,10
Dot plot 2 is the bottom plot. The value of it are as,
1,2,2,3,3,4,4,4,5,5,5,6,6,7,8,9
The options given in the problem are,
The range of the data in dot plot 1 is less than the range of the data in dot plot 2-Range is difference between the highest and lowest value. The range of the first dot plot is,
[tex]r_1=10-2=8[/tex]
The range of the Second dot plot is,
[tex]r_2=9-1=8[/tex]
Range of dot plots are equal.
The mean of the data in dot plot 1 is greater than the mean of the data in data plot 2.Mean of the dot plot one is 6.1875 and mean of the dot plot second is 4.625.
The median of the data in dot plot 1 is equal to the median of the data in dot plotThe median of the data in dot plot 1 is 6 and the median of the data in dot plot is 4.5. Thus they are not equal.
The mode of the data in dot plot 1 is less than the mode of the data in dot plot 2.The mode of the data in dot plot 1 is 6 and the mode of the data in dot plot 2 is 4 and 5. Thus this is not correct option.
Hence, in the dot plots 1 and 2, the statement which is true is that the mean of the data in dot plot 1 is greater than the mean of the data in data plot 2.

Restaurants often slip takeout menus under Rosa's apartment
door. So far, Rosa has collected 15 menus, including 5 for
Indian food. Considering this data, how many of the next 18
menus slipped under Rosa's door should you expect to be
from Indian restaurants?
Answer:
6.
Step-by-step explanation:
Since restaurants often slip takeout menus under Rosa's apartment door, and so far, Rosa has collected 15 menus, including 5 for Indian food, to determine, considering this data, how many of the next 18 menus slipped under Rosa's door should be expected to be from Indian restaurants the following calculation and logical reasoning must be performed:
5/15 = 0.333333
Thus, 1/3 of the restaurant ads correspond to Indian restaurants. Therefore, since 18 x 1/3 equals 6, the number of Indian restaurant menus that could be expected to be slid under Rosa's door is 6.

Answer:
(x+5) and (x-7).
Step-by-step explanation:
The given equation is :
[tex]x^2-2x-35[/tex]
We need to write it in factored form.
We have to find two number such that their sum is 2 and product is 35.
We know that,
7×5 = 35 and 7+(-5) = 2
So,
[tex]x^2-2x-35=x^2-7x+5x-35\\\\=x(x-7)+5(x-7)\\\\=(x+5)(x-7)[/tex]
Hence, the required factors are (x+5) and (x-7).
