Alenkasestr [34]

Answer:

inequality- 1.29m <20

maximum number of songs- 15 songs

Step-by-step explanation:

For the inequality, you see that she only has $20 so whatever she buys has to be below that so use the less than sign. You also see that each song is worth $1.29 so 1.29m. For the maximum number of songs, you divide 20 by 1.29 and just ignore the remainder.

1a. [1 mark] The price per kilogram of tomatoes, in euros, sold in various markets in a city is found to be normally distributed

andrey2020 [161]

Answer:

The price that is two standard deviations above the mean price is 4.90.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 3.22 and a standard deviation of 0.84.

This means that $\mu = 3.22, \sigma = 0.84$

Find the price that is two standard deviations above the mean price.

This is X when Z = 2. So

$Z = \frac{X - \mu}{\sigma}$

$2 = \frac{X - 3.22}{0.84}$

$X - 3.22 = 2*0.84$

$X = 4.9$

The price that is two standard deviations above the mean price is 4.90.

Find the area of the shaded region

Luba_88 [7]

The answer is 40

Way to solve 1:
You notice that the rectangle is split into half. Find the area of the rectangle first
10x8=80

Since that is half the rectangle, you then divide it by half.
80/2=40

Way to solve 2:
You can also see it as a triangle. The length is 10 and the height is 8. The formula for solving area for triangles is below

A=hw/2
(H is height and w is width.)

Because of order of operations, we do height times width first. In this case, that is 8x10

8x10=80

Then, you have to divide that by 2.

80/2=40
