Answer: t=4.5x

Step-by-step explanation:

t=cups of tomatoes

x=batch(es) of pasta sauce

Example:

The chef wants to know how many tomatoes he needs to make 2 batches of pasta sauce.

x=2

So 4.5x2=9

Answer for the example is 9

Consider the probability that exactly 20 out of 309 people will get the flu this winter. Choose the best description of the area
noname [10]

Answer:

The distribution of proportion of people who will get the flu this winter is <em>N</em> (0.065, 0.014²).

Step-by-step explanation:

Let <em>X</em> = number of people who will get flu this year.

The sample selected is of size, <em>n</em> = 309.

The number of people who will get flu in this sample is, <em>x</em> = 20.

Compute the sample proportion of people who will get flu as follows:

p=\frac{x}{n}=\frac{20}{309}=0.065

The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> = 309 and <em>p</em> = 0.065.

The sample size is quite large, i.e. <em>n</em> = 309 > 30.

And the probability of success is low.

So the Normal approximation to Binomial can be used to approximate the distribution of sample proportion is:

  1. np ≥ 10
  2. n(1 - p) ≥ 10

Check whether the conditions are fulfilled or not as follows:

np=309\times 0.065=20.085>10\\n(1-p)=309\times (1-0.065)=288.915>10

Hence, the conditions are fulfilled.

The sampling distribution of sample proportion is:

p=N(p, \frac{p(1-p)}{n})

Compute the mean and variance as follows:

Mean=p=0.065\\Variance=\frac{p(1-p)}{n}=\frac{0.065(1-0.065)}{309}=0.014^{2}

Thus, the distribution of proportion of people who will get the flu this winter is <em>N</em> (0.065, 0.014²).

For what value of b is y = 4 a solution to the equation y + 2 = by +8
Aleksandr [31]

b = -0.5

4 + 2 = - 0.5 * 4 + 8

6 = -2 + 8

6 = 6

Which is true, Therefore the answer is -0.5

Plz helper I been ask this question about 3 times
barxatty [35]

The value of x is 35 degrees, as it is opposite to the other 35 degree angle. Now, to find y. We can see by the indicators that the measure of the y angles are equal. These angles, along with the 35 degree angle that is indicated are in a straight angle. This helps us. Form an equation.

2y+35=180

2y+35-35=180-35

2y=145

y=72.5

Therefore, the value of the x angle is 35 degrees and the value of the y angle is 72.5 degrees.

Hope this helps.
