Answer:
0.9648
Step-by-step explanation:
Given that:
p = 0.2
Sample size = Number of trials (n) = 15
Probability that atleast one person is infected.
This can be solved using the binomial probability function :
P(x = x) = nCx * p^x * (1 - p)^(n-x)
P(x ≥ 1) = p(1) + p(2) + p(3) +... + p(15)
The sum of the individual probabilities of p(1) up to p(15)
Therefore, to save computation time, we can use the binomial probability calculator :
P(x ≥ 1) = 0.9648

Solve the system of linear equations by substitution. Check your solution.
Answer:
X = -5
y = 1
Step-by-step explanation:
plug in -3x - 14 for y
x + 4 ( -3x - 14) = -1
x - 12x - 56 = -1
-11x = 55
x = -5
plug in for x
-3(-5) - 14 = y
15 - 14 = y
y = 1
plug in and it proves equal

Hi there.
The answer is C point.
Explanation:
[tex] - 4 + 3i + 6 - i \\ 2 + 2i[/tex]
Count the x-axis/Re 2 units from 0 then Im 2 units from 0 as we get C point.
The complex number (2 + 2i) is represented by letter C on the graph above.
What is a complex number?A complex number can be defined as any numerical quantity that comprises two main parts, which include a real number and an imaginary number.
In this exercise, you're required to add the given complex number as follows:
-4 + 3i + 6 - i
2 + 2i
Therefore, the complex number (2 + 2i) corresponds to point C on the graph.

A certain shade of paint is made by mixing 5 parts blue paint with 2 parts white paint. To get the same shade of paint how much white paint should be mixed with 8.5 quarts of blue paint?
Answer:
5 parts blue + 2 parts white = certain color
8.5 parts blue (= 5 /5 *8.5)
so we will need 2 /5 *8.5 = 3.4 parts white
Evaluate if m = –6 and n = –2.
2m ÷ n
–6
–4
4
6
Answer:
6
Step-by-step explanation:
Put the values of m and n into the equation.
2m ÷ n = 2(-6) ÷ -2
Evaluate.
2(-6) ÷ -2 = -12 ÷ -2
Further evaluate.
-12 ÷ -2 = 6
Answer:
the last option, 6
Step-by-step explanation:
substitute the given values into the expression:
2(-6)÷(-2)
simplify each part:
= -12÷(-2)
evaluate it: (negative divided by a negative is equal to a positive)
= 6

The initial size of the population is 300. After 1 day the population has grown to 800. Estimate the population after 6 days. (Round your answer to the nearest whole number.)
Solution :
Given initial population = 300
Final population after 1 day = 800
Number of days = 6
∴ [tex]$\frac{dP}{dt} =kt^{1/2} $[/tex]
P(0) = 300 P(1) = 300
We need to find P(8).
[tex]$dP = kt^{1/2} dt$[/tex]
[tex]$ \int 1 dP = \int kt^{1/2} dt$[/tex]
[tex]$P(t) = k \left(\frac{t^{3/2}}{3/2}\right)+c$[/tex]
[tex]$P(t)= \frac{2k}{3}t^{3/2} + c$[/tex]
When P(0) = 300
[tex]$300 = \frac{2k}{3} (0)^{3/2} + c$[/tex]
∴ c = 300
∴ [tex]$P(t)= \frac{2k}{3}t^{3/2} + 300$[/tex]
When P(1) = 800
[tex]$800 = \frac{2k}{3} (1)^{3/2} + 300$[/tex]
[tex]$500 = \frac{2k}{3}$[/tex]
∴ k = 750
[tex]$P(t)= 500t^{3/2} + 300$[/tex]
So, P(8) is
[tex]$P(t)= 500(8)^{3/2} + 300$[/tex]
= 11,614
So the population becomes 11,614 after 8 days.

if the ratio of areas of two equilateral is 25:36 then find ratio of height of the triangles
Answer:
5 : 6
Step-by-step explanation:
Given ratio of heights = a : b , then
ratio of areas = a² : b²
Here
ratio of areas = 25 : 36 , thus
ratio of heights = [tex]\sqrt{25}[/tex] : [tex]\sqrt{36}[/tex] = 5 : 6

In 2010, the average annual electricity consumption for a U.S. residential utility customer was 11,500 kWh, an average of nearly 960 kWh per month. If Plant Scherer were to supply 50% of its electricity to residential customers, how many residences could the plant supply with electricity if it were running at 60% average capacity for an entire year
Answer:
If Plant Scherer supplies 50% of its electricity to residential customers, it could supply 849,962 residential customers per year.
Step-by-step explanation:
Plant Scherer capacity = 930 megawatts * 4 plants = 3,720 MW
3,720 MW * 1,000 = 3,720,000 kW
At 60% production, it will produce 2,232,000 kW (3,720,000 * 60%)
50% for residential utility customers = 1,116,000 kW (2,232,000 * 50%)
Average annual consumption per residence = 11,500 kWh
Per hour consumption = 11,500/8,760 = 1.313 kW per residence
Therefore, the number of residential customers it could supply in a year
= 1,116,000/1.313
= 849,962 residential customers .
