Answer:

Even if a person doesn't show symptoms, they can still have it.

Step-by-step explanation:

That's the problem.

Even if you think everyone isn't sick, they very well could be, and because there is no vaccine and it spreads so quickly, there's a chance that all the people in that group could get it.

Answer:

Option B) is a continuous probability distribution

Step-by-step explanation:

Properties of a normal probability distribution:

The mean, mode and median of the data is same.
It is a continuous probability distribution.
The area under the curve is 1.
The probability that any random variable X at a particular value is zero.

Thus, from the properties of normal distribution, the correct answer is:

Option B) is a continuous probability distribution

How many triangles can be constructed with angles measuring 120°, 40°, and 10°? one more than one none

FrozenT [24]

I might be wrong but i believe you can make more than one with those 3 angles. the 120 and 40 can make one and if angled right can make 2 and the 10 deg on one of the other angles lines would give you a 3rd.

Can someone help me with this? Ava uses 8⁄9 gallonsof water every time she waters her lemon tree. If she waters her lemon tree 1

Nataly_w [17]

If Ava waters her lemon tree 12 times, then she has used 10.667 gallons of water.

Solution:

Given that , Ava uses $\frac{8}{9}$ gallons of water every time she waters her lemon tree.

If she waters her lemon tree 12 times, we have to find how much water will she use

Total water used = water used for 1 time $\times$ number of time water used for plants

Here water used for one time = $\frac{8}{9} gallons$

Number of time watered = 12

$\text { Total water used }=\frac{8}{9} \text { gallons } \times 12 \text { times }$

$\text { Total water used }=\frac{8}{9} \times 12=\frac{8}{3} \times 4=\frac{32}{3}=10.667$

Hence, Ava used 10.667 gallons of water.

In proof testing of circuit boards, the probability that any particular diode will fail is 0.01. Suppose a circuit board contain

castortr0y [4]

Answer: a) 2 b) 1.407

Step-by-step explanation:

Given : The probability that any particular diode will fail : p=0.01

The number of diodes in a circuit : n= 200

The number of diodes expected to fail will be :-

$\mu= np=(200)(0.01)=2$

Hence, the number of diodes expected to fail =2

The standard deviation of the number that are expected to fail will be :-

$\sigma=\sqrt{np(1-p)}\\\\\Rightarrow\sigma=\sqrt{200(0.01)(1-0.01)}\\\\=1.40712472795\approx1.407$ [Rounded to three decimal places.]

Hence, the standard deviation of the number that are expected to fail= 1.407
