In a shipment of 62 vials, only 14 do not have hairline cracks. if you randomly select 3 vials from the shipment, what is the probability that all 3 of the selected vials have hairline cracks?
The probability that all three of the selected vials have hairline cracks = 0.096
Total number of vials in the shipment = 62
Number of vials with hairline cracks = 14
Number of vials without hairline cracks = 48
Three from 62 vials are selected.
So total outcomes = 62C3
Number of possible outcomes for all 3 of selected vials have hairline cracks = 14C3, which is the number of favorable outcomes
Probability that all three of the selected vials have hairline cracks = Number of favorable outcomes/Total outcomes = 14C3/62C3 = 0.096

9) The True Distance is 209 ft
10) The True Distance is; 66.5 ft
11) The True Height is; 57 ft
How to Interpret the Scale of a Map?We are given that the scale of the map is 1 in : 38 ft
This means that 1 inch represents 38 ft
9) Now, we want to find the true distance of 5.5 inches from the map. Thus;
True distance = (5.5 * 38)/1
True Distance = 209 ft
10) Now, we want to find the true distance of 1.75 inches from the map. Thus;
True distance = (1.75 * 38)/1
True Distance = 66.5 ft
11) We are given the scale is 1 in : 85 ft.
Thus, the true height of 1.5 inches is;

(2x-1)+4x+(12x+5)=114
Answer: Answer is 6.11
Step-by-step explanation:
Lets solve this equation (2x-1)+4x+(12x+5)=114
step 1: we first add x variables
ie. 2x + 4x + 12x = 18x
step 2: we add numbers
ie. -1 + 5 = 4
step 3: now we arrange LHS part
ie. 18x + 4 = 114
step 4: now move this 4 to right hand side and simplify them
ie. 18x = 114 - 4 = 110
step 5: now we divide 110 by 18 to get the value of x
ie. x = 110/18 = 6.11

A coordinate plane with a straight line with a negative slope. The line passes through (negative 2, 2) and (2, 1).

A two-column table with five rows. The first column, x, has the entries, negative 12, negative 11, negative 10, and negative 9. The second column, y, has the entries, 7, 11, 14, and 17.
Answer:
(A) is correct.
Step-by-step explanation:
As we know,
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
From the first graph:
The line goes through the points:
(-2, 2) and (2, 1)
y - 1 = (1-2)/(2+2)[x -2]
y - 1 = (-1/4)[x -2]
y = -x/4 + 1/2 + 1
y = -x/4 + 3/2
The constant additive rate of change = -1/4
Thus, the function shown in graph (A) has a constant additive rate of change is -1/4 option (A) is correct.

A man drove 14 mi directly east from his home, made a left turn at an intersection, and then traveled 9 mi north to his place of work. if a road was made directly from his home to his place of work, what would its distance be to the nearest tenth of a mile?
If a road was made directly from his home to his place of work, its distance will be 16.6 mi.
If a man drives east from his home, makes a left turn at an intersection, and then travels north to his place of work, then the path he travels resembles the sides of a right triangle (see attached photo).
if a road was made directly from his home to his place of work, then this path will be the hypotenuse of the triangular path.
Using Pythagorean theorem, we can solve for the distance of the road.
c^2 = a^2 + b^2
where c is the distance of the road
a is the distance he travels to the east
b is the distance he travels up north
c^2 = a^2 + b^2
c^2 = (14 mi)^2 + (9 mi)^2
c^2 = (196 + 81) mi^2
c^2 = 277 mi^2
c = 16.64331698 mi
distance of the road = c = 16.64331698 mi

f + 129° = 180° ( being the angle in linear pair )
Again ,
d + 90° = 180° ( being the angle in linear pair )

Answer:
d = 90° , e = 129° , f = 51°
Step-by-step explanation:
d and 90° are a linear pair and sum to 180° , that is
d + 90° = 180° ( subtract 90° from both sides )
d = 90°
e and 129° are vertically opposite angles and are congruent , then
e = 129°
f and 129° are a linear pair and sum to 180° , that is
f + 129° = 180° ( subtract 129° from both sides )

ZA and ZB are vertical angles. If mA = (5x +24)° and m/B= (6x - 5)°,
then find the measure of ZB.
The measure of ∠B = 189°
Here it is given that
∠A = (5x + 24)° and ∠B = (6x - 5)°
∠A and ∠B are vertical angles
Since vertical angles are always equal so
∠A = ∠B
5x + 24 = 6x - 5
add +5 on both sides, we get
5x + 24 + 5 = 6x - 5 + 5
5x + 29 = 6x
add -5x on both side, we get
5x - 5x + 29 = 6x - 5x
x = 29
Now put the value of x in 6x - 5
6 × 29 - 5 = 189
The measure of ∠B = 189°
