The answer is 50,000. It is 50,000 because 450 times 1000 equals 450,000. And 500,000 minus 450,000 equals 50,000

Or 450 x 1000= 450,000

500,000 - 450,000= 50,000

A bag contains 33 red marbles, 6 white marbles, and 5 gray marbles. You randomly pick out a marble, record its color, and put it

Ksju [112]

<h3>Total 73 times we can expect white or gray marbles.</h3>

Step-by-step explanation:

Total number of marbles = 33

Number of white marbles = 6

Number of gray marbles = 5

Now, as we need to pick white or gray marbles, so favorable outcomes

= 6+ 5 = 11 marbles

Now, P(Picking out 1 white or gray marble) = $\frac{\textrm{Total Favorable outcomes}}{\textrm{Total Outcomes}} = \frac{11}{33} = (\frac{1}{3})$

Here, the same experiment is repeated 220 times.

So, the Combined Prediction

= Probability at first attempt x Number of repetitions

$= (\frac{1}{3} ) \times 220 = \frac{220}{3} = 73.33 \approx 73$

⇒The combined prediction after 220 attempts = 73

Hence, total 73 times we can expect white or gray marbles.

What is the risk of going into a group of more than 20 or more people at this time from coronavirus?

olga55 [171]

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.

KiRa [710]

Answer:

Null Hypothesis, $H_0$ : $\mu$ = 1,100 square feet

Alternate Hypothesis, $H_A$ : $\mu$ < 1,100 square feet

Step-by-step explanation:

We are given that the mean area of several thousand apartments in a new development is advertised to be 1,100 square feet.

A consumer advocate has received numerous complaints that the apartments are smaller than advertised.

Let $\mu$ = mean area of several apartments.

So, Null Hypothesis, $H_0$ : $\mu$ = 1,100 square feet

Alternate Hypothesis, $H_A$ : $\mu$ < 1,100 square feet

Here, null hypothesis states that the mean area of apartments are same as advertised.

On the other hand, alternate hypothesis states that the mean area of apartments are smaller than advertised.

So, this would be the appropriate null and the alternative hypothesis to test this claim.
