7 of the sweets in the bag are strawberry. Since there are 20 sweets total in the bag, 20 - 7 = 13 sweets in the bag must be non-strawberry.

The probability that a sweet taken at random from the bag is not strawberry would thus be 13/20.

Answer:

See below

Step-by-step explanation:

The three angles inside of the triangle sum to 180

11x + 4 + 3x + 78 = 180

14x +82 =180

x = 7

then B = 11x + 4 = 11(7) + 4 = 81 degrees

C = 3x = 21 degrees

A population of values his normal distribution with men equal to 27.6 and standard deviation equal 39.4 do you intend to draw a

Alecsey [184]

Answer:

The mean of the distribution of sample means is 27.6

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 27.6

Standard Deviation, σ = 39.4

We are given that the population is a bell shaped distribution that is a normal distribution.

Sample size, n = 173.

We have to find the mean of the distribution of sample means.

Central Limit theorem:

It states that the distribution of the sample means approximate the normal distribution as the sample size increases.
The mean of all samples from the same population will be approximately equal to the mean of the population.

Thus, we can write:

$\mu_{\bar{x}} = \mu = 27.6$
