What’s the answer to 14?
vfiekz [6]

Answer:

  • |t -(-5)| = 1.5
  • [-6.5, -3.5] = [minimum, maximum]

Step-by-step explanation:

The magnitude of the difference between the temperature (t) and -5 will be 1.5 at the limits:

  |t -(-5)| = 1.5

This is equivalent to two equations:

  • t +5 = -1.5
  • t +5 = 1.5

In each case, the equation is solved by subtracting 5 from both sides:

  • t = -6.5 . . . . minimum allowed temperature
  • t = -3.5 . . . . maximum allowed temperature

A recent survey of
Serga [27]

Answer:

The total number of students in a survey is 300.

Let the number of junior male(JM) be x and the number of senior males(SM) be y.

Let the number of junior female(JF) be p and the number of senior males(SF) be q.

It is given that there are 160 males, 80 junior females, 130 seniors.

Since number of males are 160. So the number of females are,

300-160=140

Since number of junior females is 80.

JF+SF=140\\80+SF=140\\SF=60

Since number of seniors are 130.

SM+SF=130\\SM+60=130\\SM=70

Since number of males is 160.

JM+SM=160\\JM+70=160\\JM=90

Therefore, the table and venn diagram is shown below.

Natalka [10]

Answer:

The answer to your question is 12.5 %

Step-by-step explanation:

Data

Total points = 168

Points scored in the regular season = 147

Percent of points scored in the playoff game = ?

Process

1.- Calculate the points scored in the playoff game

  Points in playoff game = 168 - 147

                                          = 21

2.- Calculate the percent of points scored in the playoff game using proportions

                      168 points -------------------- 100%

                        21 points --------------------- x

                        x = (21 x 100) / 168

                        x = 2100 / 168

                        x = 12.5 %
