Step-by-step explanation:
If events A and B are independent, P(A) = 0.62, and P(
BA) = 0.93, what is P(B)?
O 0.41
O 0.93
O None of the other answers are correct
O 0.58
O 0.67
Answer:
Step-by-step explanation:
you’re given A=0.62 and B/A=0.93
you’re solving for B
substitute your A value of 0.62
B/0.62=0.93
same as B/0.62=0.93/1
now cross multiply
B= 0.62x0.93
B=0.5766
B=0.58
if p (n,3)=1320what is n
Answer:
n=12
Step-by-step explanation:
lol we meet again
just use the permutation formula for this one.
n!/(n-3)!=1320
[n×(n-1)×(n-2)×(n-3)!]/(n-3)!=1320
n(n-1)(n-2)=1320
(n²-n)(n-2)=1320
n³-3n²+2n-1320=0
n=12

Step-by-step explanation:
use pythageran theorem
c=square root of a2+b2
but we are solving angle b
so
b2=c2-a2
b2=225-196
b2=29
b approximately = 5.39 Rounded up
Answer:
5.4
Step-by-step explanation:
c² = a² + b²
15² = 14² + b²
225 = 196 + b²
b² = 225 - 196
b² = 29
b = 5.4

ALSO ITS NOT A
Answer:
I believe it's C
Step-by-step explanation:
The surface area of the bottom is 64 because it's 8 times 8.
All of the sides are 8 times 12.
8 times 12 is 96.
96 times 4 (for all four sides) is 384.
So the sides (384) plus the bottom (64) is 448, or C
does a triangle with side lengths 10, 49.5, and 50.5 form a right triangle ?
Answer:
yes
Step-by-step explanation:
Use Pythagorean Theorem:
10² + 49.5² = 50.5² ??
100 + 2450.25 = 2550.25
2550.25 = 2500.25

Which function represents transforming ƒ(x) = 3x with a reflection over the x-axis and a vertical shift of 4 units?
A) h(x) = 3x + 4
B) h(x) = -3x + 4
C) h(x) = 3x-4
D) h(x) = -3x+4
Answer:
B. h(x) = -3x + 4.
Step-by-step explanation:
I am assuming that the vertical shift is upwards,
A refection in the x axis gives -3x
Vertical shift upwards of 4 gives -3x + 4.
A room measures 15 ft by 20 ft by 10 ft. If a basketball has a diameter of 9.6 inches, approximately how many basketballs will be needed to fill the room?
Answer:
10344.827586 basketballs
Step-by-step explanation:
A room measures 15 ft by 20 ft by 10 ft. If a basketball has a diameter of 9.6 inches, approximately how many basketballs will be needed to fill the room?
Step 1
We find the volume of the room
The room is rectangular in shape
Volume = Length × Width × Height
= 15ft × 20ft × 10ft
= 3000ft³
Step 2
Basket ball is spherical in shape
Volume of a sphere = 4/3πr³
Diameter = 9.6 inches
Radius = Diameter/2 = 9.6 /2 = 4.8 inches
Convert Radius from inches to ft
= 4.8inches/12
= 0.408333 feet
Volume of a sphere = 4/3 × π × 0.408333³
= 0.29 ft³
Step 3
3000 ÷ 0.29

A climber is ascending the face of a 500-foot high vertical cliff at 5 feet per minute. Her climbing partner is observing from 150 feet away. Find the function that describes the amount of time climbing as a function of the angle of elevation of the observer’s line-of-sight to the climber. Does the viewing angle ever reach 75 degrees?
Answer:
a) t (α) = 30 * tan α
b) α = 75 ° is not possible because
Step-by-step explanation:
The vertical cliff (y), the observing partner ( 150 ft ) from the point o ( the common point for the cliff and the ground ) between the cliff, and the line of sight from the observer and the climber, shape a right triangle. Hypothenuse is the distance between the partners, the cliff, and distance of the observer to the cliff are the legs.
Then
α is the elevation angle
tan α = y / 150 (1)
y(t) = elevation of the climber
y(t) = speed * time
y(t) = 5 * t
tan α = 5 *t / 150
tan α = t / 30
t (α) = 30 * tan α
b) α = 75 ° is not possible because:
tan α = y / 150 tan 75° = 3.73
Then y = 3.73 * 150 = 559 ft and the cliff is only 500 ft

Use a formula to find the amount of wrapping paper you need to wrap a gift in the cylindrical box shown. You need to cover the top, bottom, and all the way around the box. Use 3.14 for .
Answer:
Total wrapping paper need = 960.84 inch²
Step-by-step explanation:
Given:
Height of cylinder box = 8 inch
Radius of cylinder box = 9 inch
Find:
Total wrapping paper need
Computation:
Total wrapping paper need = Total surface area of cylinder
Total surface area of cylinder = 2πr(h + r)
Total wrapping paper need = 2[3.14][9][8+9]
Total wrapping paper need = 2[3.14][9][17]
Total wrapping paper need = [6.28][9][17]
Total wrapping paper need = [56.52][17]
Total wrapping paper need = 960.84 inch²
Find the area of the figure. Sides meet at right angles NO LINKS
Answer:
105 m²
Step-by-step explanation:
Dividing the figure into 3 rectangle will be easier to find its area.
The area of the larger rectangle
= (10-5) × 13
= 65 m²
The total area of the 2 smaller rectangles
= 2 × (4×5)
= 40 m²
The area of the figure
= 65 + 40
= 105 m²

Answer:
1
Step-by-step explanation:
BD = BC + CD = (7 + 17x)
BE = BA + AE = (8 + 13x)
By intersecting secants theorem:
[tex] BC\times BD = BA\times BE[/tex]
[tex] 7(7+17x) = 8(8+13x)[/tex]
[tex] 49+119x = 64+104x[/tex]
[tex]119x -104x = 64-49[/tex]
[tex]15x = 15[/tex]
[tex]x = \frac{15}{15}[/tex]
[tex]x =1[/tex]

Find the area of the regular polygon.
The perimeter of 14 and radius of 2.5
Answer:
The area of the regular polygon is 17.5.
Step-by-step explanation:
To find the area of the regular polygon with a perimeter of 14 and radius of 2.5, the following calculation must be performed, knowing that the area of a regular polygon arises from multiplying the perimeter by the apothem divided by two:
(14 x 2.5) / 2 = X
35/2 = X
17.5 = X
Therefore, the area of the regular polygon is 17.5.

Find the quotient of 7/8 divided by 1/4 by using the procedure. Write your answer as a proper fraction, whole number or mixed number
Answer:
7/8 x 4/1
make 1/4 a reciprocal (basically just turning the fraction upside down)
then turn the division sign into a multiplication sign and multiply across:
7/8 x 4/1 = 28/8 = 3 4/8 = 3 1/2
