Answers

Answer 1

Answer:

Number of boys = 12

Number of girls = 36

Step-by-step explanation:

Number of boys = x

Number of girls = 3*x = 3x

Total students = 48

x + 3x = 48

   4x = 48

    x = 48/4

    x = 12

Number of boys = 12

Number of girls = 3*12 = 36

9. Bianca is hosting a dinner party for 10 people. The main course's recipe states
that 400 g of sausage and 500 g of dry pasta is enough for four people.
a) How much sausage will she need?
b) How much pasta will she need?​

Answers

Answer:

a) 1000 grams

b) 1250 grams

Step-by-step explanation:

Find out how much grams of sausage and dry pasta she needs for each person.

4 people = 400 g

1 person = 400 ÷ 4 = 100 g (sausage)

4 people = 500 g

1 person = 500 ÷ 4 = 125 g (dry pasta)

Find out how much grams of sausage and dry pasta is needed for 10 people.

10 person = 100 x 10 = 1000g (sausage)

10 person = 125 x 10 = 1250g (dry pasta)

A figure has vertices A = (0, 0), B = (1, 3), C = (0, 4), and D = (-1, 1).

The distance between AB is given as,

AB = √[(1 - 0)² + (3 - 0)²]

AB = √10 units

The distance between AD is given as,

AD = √[(-1 - 0)² + (1 - 0)²]

AD = √2 units

The measure of the adjacent sides is not equal. Then the MOST precise classification for figure ABCD will be a parallelogram.

Parking at a large university has become a very big problem. University administrators are interested in determining the average parking time (e.g. the time it takes a student to find a parking spot) of its students. An administrator inconspicuously followed 250 students and carefully recorded their parking times. The university is interested in using the information from the sample of 250 students collected to learn information about the entire student parking population. Would this be an application of descriptive or inferential statistics

Answers

Answer:

Inferential statistic

Step-by-step explanation:

The art of making deductions or data driven predictions from statistical data refers to an aspect of statistics called Inferential statistics. Inferential statistics differs from descriptive statistics which is another aspect which focuses on presenting characteristics of data. Here, we make statistical deductions about the entire population from the results obtained about the sample statistic. In the scenario above, the statistic derived from the sample data will be used to make deductions about the general population of students who park in the university. Therefore, from the statistic obstaied from the sample, we infer about the population.
