prohojiy [21]

As in each table can seat 8 people and the probability you need to find is about the first person you can ignore this data.

Probability that the first person to enter the room will be randomly seated at a maple table:

$P(maple)=\frac{#maple\text{ }tables}{#total\text{ }tables}$

#maple tables: 9

# total tables: 9 +10 +5 +7=31

$P(maple)=\frac{9}{31}$ Then, the probability that the first person to enter the room will be randomly seated at a maple table is 9/31

Answer:

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 90°

a point (x, y) → (- y, x)

A translation of 3 units up → + 3 in the y- direction, that is add 3 to the y- coordinate, hence

(x, y) → (- y, x) → (- y, x+ 3) → D

State the domain of d.

tester [92]

d(x) = { (x,y): y = sqrt(x) and y >=0 }

since sqrt function requires x to be >=0 so

x >= 0

The specifications for an electronic device state that it is to be operated in a room with relative humidity ℎ defined by |ℎ − 5

Nadya [2.5K]

Answer: $\Large\boxed{20 < h < 80}$

Step-by-step explanation:

Given inequality

$|h-50| < 30$

The goal of the question

To find the minimum and maximum of the relative humidities

For this question, we need to solve the inequality

Simplify the absolute value sign

$h-50 < 30$ or $h-50 > -30$

Add 50 on both sides

$h-50+50 < 30+50$ or $h-50+50 > -30+50$

$\Large\boxed{h < 80}$ or $\Large\boxed{h > 20}$

Hope this helps!! :)
