Oliva picked 256 strawberries from the orchard fields. She divided strawberries evenly to 6 baskets. How many strawberries are in each basket? How many are leftover?

Answer:

0.4 - 0.40 - 4/10 -

Step-by-step explanation:

Answer: -5, 6

Step-by-step explanation:

Answer:

357 mi²

Step-by-step explanation:

The shape is made of a triangle and a half-square

we will calculate the area of each one

• The half square:

let A1 be the area of the half-circle:

A1= (10²*π)/2 = 50π mi²

• The rectangle:

Let A2 be the area of the triangle:

A2= 10*20=200 mi²

• The whole shape:

let At be the total area:

At =A1+A2= 200+50π =357.07≈ 357 mi²

Answer:

The probability that there will be less than 45.1% questions of general facts that Siri answers correctly is 0.5636.

Step-by-step explanation:

Let X = number of times Siri is known to answer general facts correctly.

The probability of random variable X is, P (X) = p = 0.4452.

The sample selected is of size, n = 181.

The random variable

As the sample size is large, i.e. n > 30 and the [probability of success is closer to 0.50, i.e.p is close to 0.50, then the binomial distribution can be approximated by the normal distribution.

Also if np ≥ 10 and n (1 - p) ≥ 10 then binomial distribution can be approximated by normal distribution.

Check the conditions as follows:

• n = 181 > 30
• p = 0.4452 is closer to 0.50
• np = 181 × 0.4452 = 80.5812 > 10
• n (1 - p) = 181 × (1 - 0.4452) = 100.4188 > 10

All the conditions are satisfied.

Then the sample proportion () follows a Normal distribution.

Mean =

Standard deviation =

Compute the probability that there will be less than 45.1% questions of general facts that Siri answers is correct as follows:

**Use the z-table for probability.

Thus, the probability that there will be less than 45.1% questions of general facts that Siri answers correctly is 0.5636.
