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
For the equations given below, which statement is true? A. The equations do not have the same solution because the second equation can never be obtained when multiplying the first equation by any value. B. The equations have the same solution because the second equation can be obtained by multiplying both sides of the first equation by −3. C. The equations have the same solution because the second equation can be obtained by multiplying both sides of the first equation by 3. D. The equations have the same solution because the second equation can be obtained by multiplying both sides of the first equation by −4.
i want to fined out that
a^2+b^2
________is equal to?
a+b
Answer:
(a+b)²-2ab
Step-by-step explanation:
First we need to factorize (a+b)²
(a+b)² = a² + 2ab + b²
(a+b)² = a²+b²+2ab
Subtract 2ab from both sides
(a+b)² - 2ab = a²+b²+2ab - 2ab
(a+b)²-2ab = a²+b²
Swap;
a²+b² = (a+b)²-2ab
Hence the expression of a² + b² is (a+b)²-2ab

Answer: [tex]7,5.66,39^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]IJ=9\\\angle I=51^{\circ}[/tex]
from figure, we can write
[tex]\Rightarrow \sin 51^{\circ}=\dfrac{HJ}{9}\\\\\Rightarrow HJ=9\sin 51^{\circ}=6.99\approx 7[/tex]
[tex]\Rightarrow \cos 51^{\circ}=\dfrac{HI}{9}\\\Rightarrow HI=9\cos 51^{\circ}\\\Rightarrow HI=5.66[/tex]
In right angle trianle, the sum of the remaining two angles is [tex]90^{\circ}[/tex]
[tex]\therefore 51^{\circ}+\angle J=90^{\circ}\\\Rightarrow \angle J=90^{\circ}-51^{\circ}\\\Rightarrow \angle J=39^{\circ}[/tex]

if each box represents 1 miles, what is the shortest distance from the school to the skate park.
The shortest distance between two points is a straight line.
Use the distance formula for points.
In the diagram, we are given two points:
(4,2) and (-3,0).
Let d = distance between the two points.
d = sqrt{(-3 -4)^2 + (0-2)^2}
d = sqrt{(-7)^2 + (-2)^2}
d = sqrt{49 + 4}
d = sqrt{53}
d = 2.2360679775
d = 2.2 miles
In 1980, there were 1.2 million elephants living in Africa.

The sum of three numbers is 84, the second number is 2 times the 3rd , the first number is 8 more than the 3rd. What are the numbers
Answer:
a = 27
b = 38
c = 19
Step-by-step explanation:
a + b + c = 84
b = 2c
a = 8+c
8+c +2c+c = 84
4c + 8 = 84
4c = 76
c = 19
b = 2(19) = 38
a = 8 + 19 = 27

Answer:
27.6 is the area
Step-by-step explanation:
Area of the given triangle is equals to [tex]27.6 in^{2}[/tex](round to nearest tenth).
What is triangle?" Triangle is defined as two dimensional geometrical shape with three vertices, three sides and three angles enclosed in it."
Formula used
Pythagoras theorem
(Hypotenuse)² = (Base)² + (Height)²
Area of a right triangle = [tex]\frac{1}{2} \times b\times h[/tex]
[tex]b[/tex] represents the base of the triangle
[tex]h[/tex] represents the height of the triangle
According to the question,
In a given triangle,
Hypotenuse [tex]= 11in[/tex]
Height [tex]= 6in[/tex]
Substitute the value in Pythagoras theorem to get the measure of base,
[tex](11)^{2} = b^{2} + 6^{2}\\\\\implies b^{2}= 121 -36\\\\\implies b =\sqrt{85}[/tex]
Substitute the value in the formula to find area of a triangle,
Area of a triangle [tex]= \frac{1}{2}\times \sqrt{85} \times 6[/tex]
[tex]= \frac{1}{2} \times 9.22 \times 6\\\\= 9.22 \times 3\\\\= 27.66[/tex]
≈ [tex]27.6in^{2}[/tex] ( round to nearest tenth)
Hence, area of the given triangle is equals to [tex]27.6 in^{2}[/tex](round to nearest tenth).

Calculate the surface area of an open cylinder measuring 35cm in diameter and 60cm high.
Answer:
6598.2 in^2
Step-by-step explanation:
Given data
Diameter= 35in
Radius= d/2= 35/2= 17.5in
Height = 60cm
The expression for the curve surface area of a cylinder is
CSA=2πrh
substitute
CSA= 2*3.142*17.5*60
CSA= 6598.2 in^2
Hence the CSA is 6598.2 in^2
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
