Ben and Tom each take their driving test. The probability that ben and tom will pass is 0.8 and 0.7, respectively. Work out the probability that only one of them will pass their driving test.
Answer:
Pr(only one of them will pass the driving test) = 0.38
Step-by-step explanation:
The probability that Ben will pass = 0.8
Let Pr = pribability
Pr(Ben pass) = 0.8
Pr(Ben fail) = 1 - Pr(Ben pass) = 1-0.8
Pr(Ben fail) = 0.2
The probability that Tom will pass = 0.7
Pr (Tom pass) = 0.7
Pr (Tom fail) = 1 - Pr (Tom pass) = 1-0.7
Pr (Tom fail) = 0.3
Pr(only one pass) = Pr(Ben pass and Tom fail) + Pr (Tom pass and Ben fail)
Pr(only one pass) = (0.8 × 0.3) + (0.7 × 0.2)
Pr(only one pass) = 0.24 + 0.14
Pr(only one pass) = 0.38
Answer:0.38

Calvin builds a form for a new cement step. The form he builds is 35 1/2in. Long, 20 in. Deep, and 6 in. High. How much cementis needed to fll the form?
Answer:
231.78 lbs
Step-by-step explanation:
total amount of cementis needed= volume of form
volume of form in ft³= length × depth × height
= 35.5/12 × 20/12 × 6/12
= 2.465ft³
density of cement= 94.01651 lb/ft³
mass of cement= density × volume
= 2.465 × 94.01651
= 231.78lb
Find the center and radius of the circle described by the equation x2 + y2 + 6x - 4y - 27 = 0.
Answer:
Step-by-step explanation:
hello :
x²+ y² + 6x - 4y - 27 = 0 means : (x²+6x+9)-9+(y²-4y+4)-4-27 =0
(x+3)²+(y-2)² = 40....standard form when the center is (-3 , 2) and radius √40
The center is (-3, 2), and the radius root40.
We have given
x²+ y² + 6x - 4y - 27 = 0
It can be written as
(x²+6x+9)-9+(y²-4y+4)-4-27 =0
Write the given equation in standard form
What is the standard form of the circle?
(x-a)^2+(y-b)^2=r^2
Where (a,b) be the center and
r-is the radius of the circle
(x+3)²+(y-2)² = 40
Compare the above equation with the standard form of the equation
The center is (-3, 2), and the radius root40.

give that a load of mass 20kg is acted upon by a force of 60N calculate the acceleration of the load
Answer:
[tex]3m/s^2[/tex]
Step-by-step explanation:
the information that we have is:
mass: [tex]m=20kg[/tex]
force applied: [tex]F=60N[/tex]
since we need to find the acceleration, we can use Newton's second law of motion:
[tex]F=ma[/tex]
Where [tex]F[/tex] is the force applied to a mass [tex]m[/tex] which creates an acceleration [tex]a[/tex].
we solve this equation for the acceleration:
[tex]a=\frac{F}{m}[/tex]
and we substitute the known values:
[tex]a=\frac{60N}{20kg} \\\\a=3m/s^2[/tex]
the acceleration of the load is: [tex]3m/s^2[/tex]

The numbers $1,$ $2,$ $\dots,$ $10$ are to be entered into the 10 boxes shown below, so that each number is used exactly once: \[P = (\square + \square + \square + \square + \square)(\square + \square + \square + \square + \square).\]What is the maximum value of $P$? What is the minimum value of $P$?
Hint
If we define x to be the value of one of the factors, since 1 + 2 + 3 + 4 + 5 ... + 10 = 11(5) = 55, the value of the other factor has to be 55-x.
To maximize P, you'd like to make x as close as possible to the vertex you found. What if you want to minimize P? Remember x must be an integer.

What are domain and range?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.
Given data ,
Let the function be represented as A
Now , the value of A is
f ( x ) = ( x - 4 ) ( x - 2 ) be equation (1)
On simplifying , we get
f ( x ) = x ( x - 2 ) - 4 ( x - 2 )
f ( x ) = x² - 2x - 4x + 8
f ( x ) = x² - 6x + 8
Now , the range of the function is set of possible y values
The vertex of the parabola is at ( 3 , -1 )
So , the range of the function is f ( x ) ≥ -1 and the interval is [ -1 , ∝ ]
Hence , the range of the function is f ( x ) ≥ -1

What are the x-intercept and the y-intercept of the graph of 8x – 7y = -56?
Answer:

y=0
8x - 7(0)= -56
8x = -56
x = -7
(-7, 0)
y-intercept x= 0
8(0) -7y = -56
-7y = -56
y = 8
(0, 8)
Step-by-step explanation:
The x - intercept of the equation is, (- 7, 0)
The y - intercept of the equation is, (0, 8)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The equation is,
⇒ 8x - 7y = - 56
Now, We have to find the x - intercept as;
Substitute y = 0,
⇒ 8x - 7×0 = - 56
⇒ 8x = - 56
⇒ x = - 56/8
⇒ x = - 7
And, We have to find the y - intercept as;
Substitute x = 0,
⇒ 8x - 7y = - 56
⇒ 8×0 - 7y = - 56
⇒ - 7y = - 56
⇒ 7y = 56
⇒ y = 56 / 7
⇒ y = 8

in a class of 26 student, 15 of them like maths, 13 of them like english and 9 of them don't like maths or english.
Find the probability that a student chosen at random like english but not maths.
Answer:
2/26
Step-by-step explanation:
The total number of students = 26 students
Number of students that like maths = 15 students
Number of students that like English = 13 students
Number of students that does not like English or maths = 9
We have to find the number of students that likes both Maths and English.
Therefore,
Let x be the number of student that like both Maths and English subjects
15 - x + x + 13 - x + 9 = 26
-x + 37 = 26
-x = -11
x = 11
Number of student that offer english but not math
Number of students that like English but not Maths = Number of Students that like English - Number of students that like English and Maths
= 13 - 11 = 2
Therefore, probability that a student chosen at random like English but not Maths.
Probability = Number of events ÷ Number of possible outcomes
Number of events = Number of students that like English but not Maths= 2
Number of Possible outcomes = Total number of students = 26
The probability that a student chosen at random like English but not Maths.

Answer:
As the triangle is right angled ,
sinR = 17/63
Angle R = 15.7⁰
The closest value of the measure of ∠R is,
⇒ ∠R = 15.7°
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Right triangle RST is shown below with the dimensions given in feet.
Now, By trigonometric formula;
tan x = Opposite / Adjacent
Here, Opposite side of angle R = 17 ft
And, Adjacent side = 63 ft
Hence, We get;
tan x = Opposite / Adjacent
tan R = 17 / 63
tan R = 1/9
R = 15.7°
Thus, The closest value of the measure of ∠R is,

The perimeter of the quadrilateral is P = 8 3/4 cm
Given data:
The perimeter of a quadrilateral is the sum of the lengths of all its sides. A quadrilateral is a polygon with four sides. The formula for finding the perimeter of a quadrilateral depends on the specific type of quadrilateral.
So, the sides of the quadrilateral is represented as:
AB = 3 1/2 cm
BC = 2 cm
CD = 1 4/5 cm
DA = 1 9/20 cm
So, the perimeter is P = 3 1/2 cm + 2 cm + 1 4/5 cm + 1 9/20 cm
On simplifying ,
P = 3.5 cm + 2 cm + 1.8 cm + 1.45 cm
