A) 36 cm2
B) 48 cm2
C) 90 cm2
D) 102 cm2
Answer:
B) 48cm²
Step-by-step explanation:
find the area of the 2 rectangles
A = bh
A = 9×4
A = 36
A = bh
A = 6×2
A = 12
add them up you get 48cm²

An ordinary (fair) die is a cube with the numbers through on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment. Compute the probability of each of the following events. Event : The sum is greater than . Event : The sum is not divisible by .
Complete question :
Compute the probability of each of the following events.
Event : The sum is greater than 6
Event : The sum is not divisible by 2
Answer:
7/12 ; 1/2
Step-by-step explanation:
Sample space :
2, 3, 4, 5, 6, 7
3, 4, 5, 6, 7, 8
4, 5, 6, 7, 8, 9
5, 6, 7, 8, 9, 10
6, 7, 8, 9, 10, 11
7, 8, 9, 10, 11, 12
Probability that sum is greater than 6:
Number of outcomes greater Than 6 = required outcomes = (7,7,7,7,7,7,8,8,8,8,8,9,9,9,9,10,10,10,11,11,12) = 21
Total sample space = total possible outcomes = 36
Probability = required outcome / Total possible outcomes
P(sum is greater Than 6) = 21 / 36
2.)
Obtaining an even number :
Sum not divisible by 2 = required outcomes = (3, 5, 7, 3, 5, 7, 5, 7, 9, 5, 7, 9, 7, 9, 11, 7, 9, 11) = 18
Total sample space = total possible outcomes = 36
P(sum is not divisible by 2) = 18 / 36 = 1 / 2
The area of a rectangle is 48ft2. The length is 3 times the width. Which of the following equations can be used to solve for the width?
Answer:
Width of rectangle = 4 ft
Step-by-step explanation:
Given:
Area of rectangle = 48 ft²
Length of rectangle = 3[Width of rectangle]
Find:
Width of rectangle
Computation:
Assume;
Width of rectangle = a
So,
Length of rectangle = 3[Width of rectangle]
Length of rectangle = 3a
Area of rectangle = l x b
48 = 3a x a
3a² = 48
a² = 16
a = 4
Width of rectangle = 4 ft
Length of rectangle = 3[Width of rectangle]
Length of rectangle = 3[4]
Length of rectangle = 12 ft
In certain parts of the world tuberculosis (a very treatable and curable illness) is present in 25% of the people. If a simple chest X-ray can be used as a diagnostic tool with an accuracy of 99% detection of TB if it is present. Only in 0.5% of the cases, normal people get a positive diagnosis. 2 If a person is selected at random and the diagnosis is positive, what is the probability that the person is actually infected.
Answer:
0.9851 = 98.51% probability that the person is actually infected.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Positive test
Event B: Infected
Probability of a positive test:
99% of 25%(People have the disease).
0.5% of 100 - 25 = 75%(People do not have the disease). So
[tex]P(A) = 0.99*0.25 + 0.005*0.75 = 0.25125[/tex]
Probability of a positive test and being infected:
99% of 25%, so:
[tex]P(A \cap B) = 0.99*0.25 = 0.2475[/tex]
What is the probability that the person is actually infected?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.2475}{0.25125} = 0.9851[/tex]
0.9851 = 98.51% probability that the person is actually infected.

Answer:
the length of the opposite side (x), is 27.2
Step-by-step explanation:
For the given right triangle problem;
the opposite side of the given angle, opp. = 22
the hypothenuse side, hypo. = x
given angle of the triangle, θ = 54⁰
The length of the opposite side (x), is calculated as follows;
[tex]sin \ \theta = \frac{opp.}{hypo.} \\\\sin (54) = \frac{22}{x} \\\\x = \frac{22}{sin(54)} \\\\x = 27.2[/tex]
Therefore, the length of the opposite side (x), is 27.2
What is (8x + 4) added to (15x – 12)?
Answer:
23x-8
Step-by-step explanation:
8x + 15x = 23x
4 + (-12) = -8
Answer:
[tex] \boxed{23x \: – \: 8} [/tex]
Step-by-step explanation:
(8x + 4) added to (15x – 12) =
(8x + 4) + (15x – 12) =
[Group like terms]
(8x + 15x) + (4 – 12) =
[Simplify]
23x – 8
Jake bought 4.08 pounds of apples. He knows that 1.19 pounds are Gala apples and the rest are Cameo apples. How many pounds of Cameo apples did he buy? A 2.89 B 3.11 C 3.89 D5.27
Answer:
2.89
Step-by-step explanation:
4.08-1.19 = 2.89
you just do simple subtraction
Answer:
A. 2.89 pounds
Step-by-step explanation:
4.08 pounds of apples all together subtract the Gala apples 1.19 pounds and you'll get that Jake bought 2.89 pounds of Cameo apples.
4.08 - 1.19 = 2.89

Find the volume of the following figures with the given dimension
Answer:
[tex]V=192\ in^3[/tex]
Step-by-step explanation:
Given that,
The area of base, A = 24 in²
The height of the pyramid, h = 8 in
We need to find the volume of the following figure.
The volume of pyramid is given by :
[tex]V=A\times h[/tex]
Substitute all the values,
[tex]V=24\times 8\\\\=192\ in^3[/tex]
So, the volume of the pyramid is equal to [tex]192\ in^3[/tex].

A square has a diagonal measuring 19 centimeters in length.which of the following is closest to the length of each side of the square?
Answer:
13cm
Step-by-step explanation:
Let the length of each side be x;
Using the pythagoras theorem
l² = x² + x²
l is the length of the diagonal
l² = 2x²
19² = 2x²
361 = 2x²
x² = 361/2
x² = 180.5
x =√180.5
x = 13
hence the length of each side of the square is closest to 13cm
