Step-by-step explanation:
The probability that the result of the test is positive, given that the sample doesn't contain the bacteria = 0.03
What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
The formula of the probability of an event A is:P(A) = n(A) / n(S)
, where n(A) is the number of favorable outcomes and is the total number of events in the sample space.
For given example,
Let event A : the number of result of the test is positive, given that the sample doesn't contain the bacteria
⇒ (n(A)) = 58
the total number of sample n(S) = 2000
Therefore, the probability that the result of the test is positive, given that the sample doesn't contain the bacteria would be,
⇒ P(A) = n(A)/n(S)
⇒ P(A) = 58/2000
⇒ P(A) = 29/1000
⇒ P(A) = 0.029
⇒ P(A) = 0.03
Therefore, the correct answer is option (A) 0.03

Please Help!!! I will mark the brainiest and 70 points!
Answer:
darkest shaded- 0.8 times 0.7= 0.56
In the middle- 0.8 times 0.3= 0.24 times 0.2 times 0.7= 0.14 0.24 + 0.14= 0.38
Light- 0.2 times 0.3= 0.06
0.38 + 0.06=0.44
0.56 times 0.44= 0.2464

Devante buys 1/1/4 pounds of cashews 7 ounces of almonds and 3/4 pounds of pecans how much do the nuts weight in
Answer: [tex]39\ \text{Ounces}[/tex]
Step-by-step explanation:
Given
The amount of cashews is [tex]1\frac{1}{4}\ \text{Pounds}[/tex]
Amount of almonds [tex]7\ \text{ounces}[/tex]
The amount of pecans is [tex]\frac{3}{4}\ \text{Pounds}[/tex]
We know, [tex]1\ \text{Pound}=16\ \text{Ounces}[/tex]
Converting pounds to ounces and adding them
[tex]\Rightarrow 1\dfrac{1}{4}\times 16+7+\dfrac{3}{4}\times 16\\\\\Rightarrow \dfrac{5}{4}\times 16+7+3\times 4\\\\\Rightarrow 20+7+12=39\ \text{ounces}\ or\ \dfrac{39}{16}\ \text{Pounds}[/tex]
Thus, the nuts weigh [tex]39\ \text{Ounces}[/tex]

Can I please have some help with this I am stumped
9514 1404 393
Answer:
29 in²
Step-by-step explanation:
No need to be stumped. The dashed lines divide the figure into three recognizable forms, for which you have area formulas.
The area of a rectangle or parallelogram is given by the formula ...
A = bh . . . . . where b represents the base, and h represents the height.
__
The top part of the figure is a square. That is, it is a rectangle with its base equal to its height. In this figure, both are labeled 2 in.
A = (2 in)(2 in) = 4 in² . . . . . . area of top square
The middle part of the figure is a parallelogram. Its base is the same as the base of the rectangle below it. Its height is labeled 3 in.
A = (5 in)(3 in) = 15 in² . . . . . . area of middle parallelogram
The bottom part of the figure is a rectangle with a height of 2 in. Its base is the same length we used for the parallelogram: 5 in.
A = (5 in)(2 in) = 10 in²
The area of the figure is the sum of the areas of its parts:
figure area = 4 in² + 15 in² + 10 in² = 29 in²
The area of the figure is 29 in².

Anderson won $10000 in a Lotto competition.
He banked, then he gave his wife 60% of the remainder.
He then shared what was left between his two sons Jimmy and Prince, giving Jimmy three
times as much as Prince. Calculate Jimmy's share.
Answer:
jimmy got 30,000
Step-by-step explanation:
10,000
the wife got 60% = 60,000
jimmy got 3x prince = 30,000
prince = 10,000

Find the circumference and area of a circle the radius is 7 meters
Answer: 43.9823
Step-by-step explanation:
The equation to find the circumference is c=2πr. By the “r” in the equation represents the radius. The question says the radius is 7 so you just input the 7 where the “r” is. So 2·π·7=43.9823.
C=2πr=2·π·7≈43.9823

Answer:
A=3, B=4, C=-5
Step-by-step explanation:
So A represents the amplitude, which is the distance between the midline (C), the middle of the graph, and the maximum (or minimum). B is the distance of the period of the graph. In this case, we see that the midline is C=-5 because that is the halfway point of the sine function. We also see that the period distance is B=5-1=4, so our period would be 2π/4 or π/2. Our amplitude would be A=3 because |a|=|-5-(-2)|=|-5+2|=|-3|=3. Observe the graph to see this visually.
For the following right triangle, find the side length .
Answer:
x = 25
Step-by-step explanation:
Using the formula a²+b²=c², you can easily find out the hypotenuse of the triangle (which is the long side of it, and is the x in this problem.)
If we substitute the side lengths for the question in a²+b²=c², you'll get
20²+15²=x²
Simplifying the numbers and squaring them, you get
400+225=625²
Since you want the value of the x side, you'll need to root 625.
√625=25
Therefore, x = 25
Answer:
x = 25
Step-by-step explanation:
To find the side lengths of a right triangle, we can use the Pythagorean Theorem, a² + b² = c². a and b are the legs, and c is the hypotenuse, the longest side. In this figure, x is the hypotenuse, c.
Plug in our values for a and b and solve for x.
[tex]a^2+b^2=c^2[/tex]
[tex]20^2+15^2=c^2[/tex]
[tex]400+225=c^2[/tex]
[tex]625=c^2[/tex]
[tex]\sqrt{625}[/tex] = [tex]\sqrt{c^2}[/tex]
[tex]25=c[/tex]
c, or x is equal to 25. The missing sidelength is 25 units.
Good luck ^^

Find the value of x.
101 x +29
Answer:
x = 50
Step-by-step explanation:
101 + (x + 29) = 180
130 + x = 180
x = 180 - 130
x = 50
Answer:
50°
Step-by-step explanation:
in order ro find x you would need to solve for 101° ( x + 29) = 180° if you replace x with 50 then you equation would be true!
