Question 7 options: A raffle sells 1000 tickets for $35 each to win a new car. What is the probability of winning the car
Answer:
it would be 1/1000 assuming only 1 ticket sold to 1 person each; if a person bought more than 1 ticket then there odds of winning increase
Step-by-step explanation:
The probability of winning the car is 0.001.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
Given that, a raffle sells 1000 tickets for $35 each to win a new car.
Here, we know that there is a total of 1000 tickets. If there is only one car, then definitely only one wins the raffle. The probability of winning is also dependent on the number of tickets one will purchase. But for this problem, we are going to assume that only one raffle can be bought by one person. Thus, the probability of winning a new car is simply
P(E)= Number of raffle tickets one can buy/Total number of raffle tickets
= 1/1000
= 0.001
Therefore, the probability of winning the car is 0.001.

The length of a rectangular swimming pool is 20 feet greater than the width. The surface area of the pool is 1,500 square feet. What are the length and width of the pool?
Answer:
750
Step-by-step explanation:
The length and width of the swimming pool is 50feet and 30 feet respectively.
What is surface area ?The amount of space covering the outside of a three dimensional space is called surface area.
Formula for the surface area of rectangular swimming poolsurface area = length × breadth
According to the given question
The length of the rectangular swimming pool is 20 feet greater than the width.
and, the surface area of the pool is 1,500 square feet.
Let the width of the rectangular pool be x.
⇒ length of the pool = 20+x
therefore,
surface area of pool = length × breadth
⇒1500 = x×(20+x)
⇒[tex]1500= 20x+x^{2}[/tex]
⇒[tex]x^{2} +20x-1500=0[/tex]
⇒[tex]x^{2} +50x-30x-1500=0[/tex]
⇒[tex]x(x+50)-30(x+50)=0[/tex]
⇒[tex](x-30)(x+50)=0[/tex]
⇒x=30 and -50(not possible)
⇒x=30 feet
so, the width of the pool is 30 feet.
⇒ length of the pool = x+20 = 30+20 = 50 feet.
Hence, the length of the pool is 50 feet and width of the pool is 30 feet.

Ricardo wants to install two security cameras at point A so the parking lot from side AE to side AB of the building can be monitored. Can he use two cameras, both with a field of view of 110°, installed at point A? Explain. If not, what is the minimum field of view that each camera should have?
Step-by-step explanation:
The two cameras will have total view of:
110° + 110° = 220°The angle to be viewed is:
270° - 15° = 255°This is not sufficient to cover the needed area as 220° < 255°

A. 7W + 12d
B. 84W + 24d
C. 168W + 24d
D. 168W + 60d
The expression represents the number of hours in w weeks and d days is 168 W + 24 d.
The correct option is (C).
What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
We know the number days in a week = 7
and, the number of hour in a day = 24
So, number of hour in a week = 24 x 7 = 168
Then, the expression number of hours
= 168 W + 24 d
where W is the weeks and d is days.

A person borrowef Rs 16000 from a bank at 12.5% pet annum simple intrest and lent the whole amount to shopkeeper at the sam rate of compound interest.How much will he gain in 2 years?
Answer:
The amount he gains in 2 years is Rs. 250
Step-by-step explanation:
The parameters of the amount borrowed from the bank are;
The amount borrowed, P = Rs. 16,000
The interest rate of the amount borrowed, R = 12.5%
The number of years, T = 2 years
The simple interest, I = (P × R × T)/100 = (Rs. 16,000 × 12.5 × 2)/100 = Rs. 4,000
The total amount the person is to pay bank to the bank = P + I = Rs. 16,000 + Rs. 4,000 = Rs. 20,000
The parameters of the amount lent to the shopkeeper are;
The amount lent, P = Rs. 16,000
The compound interest rate of the amount lent, R = 12.5%
The number of years, T = 2 years
The amount he receives from the shopkeeper after 2 years, A = P·(1 + R/n)^(n × T) = Rs. 16,000 × (1 + 0.125/1)^(1 × 2) = Rs. 20,250
The amount he gains in 2 years = The amount he receives from the shop keeper - The amount he gives to the bank = Rs. 20,250 - Rs. 20,000 = Rs. 250
The amount he gains in 2 years = Rs. 250.

Bananas cost 3abunchandapplescost0.50 each. If b represents the number of bunches of bananas and a represents the number of apples, which of the following expressions represents the total cost?
Considering the definition of an equation, the total cost is 0.50a + 3b.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.
The members of an equation are each of the expressions that appear on both sides of the equal sign while the terms of an equation are the addends that form the members of an equation.
Total costBeing
"a" the number of apples."b" the number of bunches of bananas.and knowing that:
Bananas cost $3 a bunch.Apples cost $0.50 each.the equation that represents the total cost is:
total cost= 0.50a + 3b

Complete each statement given w = 2(cos(90o) + i sin (90o)) and z = StartRoot 2 EndRoot (cos(225o) + i sin(225o)). In rectangular form, w = 0 + i. In rectangular form, z = – 1i. In rectangular form, w + z = –1 + i. In polar form w + z = StartRoot 2 EndRoot (cos(o) + i sin(o)
This question is based on the concept of polar form.Therefore, the expression in polar form is [tex]\bold {z = \sqrt{10(cos108.43\; + \; i \; sin108.43)}}[/tex]
Given the following complex numbers in:
w = 2(cos(90°) + i sin (90°))
As we know that,
sin 90 degree = 1
cos 90 degree = 0
Put these values in given equation,
We get,
w = 2(0+i(1))
w = 2(0)+2i
w = 0+2i
Hence the value of w in rectangular form is 0+2i .
Now solving for z:
z =√2(cos(225°) + i sin(225°))
z = √2(-1/√2+ i (-1/√2))
z = -√2/√2 - √2(-1/√2)i
z = -1 + 1i
Therefore, the value of z in rectangular coordinate is -1+ 1i.
Now solving for w + z:
w + z = 0+2i + (-1+1i)
w+z = 0+2i-1+i
w+z = -1+3i
Write w+z in polar form,
Get the modulus
|w+z| = √(-1)²+3²
|w+z| = √1+9
|w+z| = √10
Get the modulus
= tan^-1(-3)
= -71.56
[tex]\Theta[/tex] = 180 - 71.56
[tex]\Theta[/tex] = 108.43
Therefore, the expression in polar form is,[tex]\bold{z = \sqrt{10(cos108.43\; + \; i \; sin108.43)}}[/tex]

The function formula is given as
f(x) = 4(1 – x)
To find the f(-10) we will substitute into the function formula, then we have
f(-10)= 4[1-(-10)]
