Answer:
x = 4
Step-by-step explanation:
We are asked to find the value of x when [tex] \frac{7}{2} [/tex].
Note that [tex] f(x) [/tex] is also y.
What this means is, what is the value of x when y = 7/2 = 3.5.
On the graph given, trace where y = 3.5. check the x-value that corresponds with it on the point on the line.
Thus, at y = 3.5, x = 4.
Therefore,
x = 4, when [tex] \frac{7}{2} [/tex].

A weather forecaster claimed the chance of rain next week on Monday is 50% and the chance it rains on Tuesday is 80%. Is the probability that it rains next
Monday and Tuesday equal to 40%?
O Yes, because the chance of rain on Monday and the chance of rain on Tuesday are independent.
O No, because the chance of rain on Monday and the chance of rain on Tuesday are not independent.
O No, because the chance of rain Monday and the chance of rain Tuesday are not mutually exclusive.
O Yes, because the chance of rain on Monday and the chance of rain on Tuesday are mutually exclusive,
Answers
Answer:
A: Yes, because the chance of rain on Monday and the chance of rain on Tuesday are independent.
Step-by-step explanation:
We are given;
chance of rain next week on Monday is 50%. Thus;
P(rain next Monday) = 0.5
chance it rains on Tuesday is 80%. Thus;
P(rain next Tuesday) = 0.8
From independent events, we can say that;
P(A and B) = P(A) × P(B)
A and B are independent events because the probability of A doesn't affect B as is the case for rain on Monday and Tuesday given.
Thus;
P(rain on Monday & tuesday next week) = 0.5 × 0.8 = 0.4
This can also be written as 40%
Correct answer is option A since both events are independent

The weekly demand for an item in a retail store follows a uniform distribution over the range of 50 to 100. What would be the weekly demand if its corresponding computer-generated value is 0.4?a. 60b. 70c. 75d. 80
Answers
Answer: 70
Step-by-step explanation:
Given that :
Uniform range of distribution = 50 to 100
50 ≤ x ≤ 100
Difference between both values = 100 - 50 = 50
Range / difference = computer generated value
(Weekly demand - lower limit) / difference = computer generated value
(Weekly demand - 50) / 50 = 0.4
Weekly demand - 50 = 20
Weekly demand = 20 + 50
Weekly demand = 70
The weekly demand if the corresponding computer-generated value is 0.4 is given by: Option B: 70
What is the property of a uniformly distributed random variable?A uniformly distributed random variable's probability is distributed uniformly in the interval in which it is defined. Thus, if X ranges from a to b, and pertains uniform distribution, then its probability density function is given by;
[tex]f(x) = \dfrac{1}{b-a}; a < x < b\\\\f(x) = 0; x < a , b < x[/tex]
For the given case, the weekly demand(let it be tracked by random variable X) is in range 50 to 100.
The computer generated value shows:
[tex]\text{Computer generated value} = \dfrac{\text{Weekly demand} - \text{Lower limit}}{\text{difference between upper and lower limit}}[/tex]
(computer generated value is showing in range 0 to 1, the part occupied by the weekly value from starting, here as it is 0.4, so it means out of 50 values, it is 0.4 = 40% of (100 -50) = 20 (from start which is 50, thus, 50 + 20 = 70) )
As we've got:
Thus, the weekly demand is obtained as:
[tex]0.4 = \dfrac{\text{Weekly demand} - 50}{50}\\\\\text{Weekly demand} = 0.4 \times 50 + 50 = 70[/tex]
Thus, the weekly demand if the corresponding computer-generated value is 0.4 is given by: Option B: 70

Write 5^3 x √5 as a single power of 5
Answers
Multiplying two number with the same base has as result a number with the same base and the sum of the exponents so:
1/2 + 3 = 7/2
which means
5^3 x 5^(1/2) = 5^(7/2)
The expression [tex]5^{3} \times \sqrt{5}[/tex] written as a single power of 5 is [tex]5^{3\frac{1}{2} } \ OR \ 5^{\frac{7}{2} }[/tex]
To write the given expression 5^3 x √5, as a single power of 5,
First, we will write the expression properly.
[tex]5^{3} \times \sqrt{5}[/tex]
Now, to write the above expression as a single power of 5,
First, express [tex]\sqrt{5}[/tex] in index form
By law of indices [tex]\sqrt{x} = x^{\frac{1}{2} }[/tex]
∴ [tex]\sqrt{5} = 5^{\frac{1}{2} }[/tex]
Now, the expression becomes
[tex]5^{3} \times 5^{\frac{1}{2} }[/tex]
Also, by law of indices, [tex]x^{y} \times x^{z} = x^{y+z}[/tex]
∴ [tex]5^{3} \times 5^{\frac{1}{2} } = 5^{3+\frac{1}{2} }[/tex]
[tex]= 5^{3\frac{1}{2} } \ OR \ 5^{\frac{7}{2} }[/tex]
Hence, the expression [tex]5^{3} \times \sqrt{5}[/tex] written as a single power of 5 is [tex]5^{3\frac{1}{2} } \ OR \ 5^{\frac{7}{2} }[/tex]

Rotational Symmetry: What Is It?A form possesses rotational symmetry, often referred to as radial symmetry, when it maintains its appearance following a partial turn rotation.
The number of alternative orientations in which an object can seem exactly the same for each revolution is the degree of rotational symmetry of that object.
Because of rotational symmetry, the figure should maintain its original appearance even when rotated. So a rhombus is the shape that exhibits rotational symmetry. So, D is the right answer.

There are an equal number of pennies, nickels, dimes, and quarters in a bag. What is the probability that the combined value of the four coins randomly selected with replacement will be $.41? express your answer as a fraction in the simplest form.
Answers
The probability that the combined value of the four coins randomly selected with replacement will be $.41 is 3/32
In this question, there are an equal number of pennies, nickels, dimes, and quarters in a bag.
We need to find the probability that the combined value of the four coins randomly selected with replacement will be $.41
Out of 41 cents, 1 must be a penny.
And the remaining three (a nickel, dime, and a quarter) must add up to 40 cents.
The first coin must be penny so, its probability P1 = 1
The probability for the second coin would be,
P2 = 3/4
The probability for the third coin would be,
P3 = 2/4
P3 = 1/2
And the probability for the fourth coin would be,
P4 = 1/4
Since the events are independent, the resultant probability would be,
P = P1 × P2 × P3 × P4
P = 1 × 3/4 × 1/2 × 1/4
P = 3/16 × 1/2
P = 3/32
Therefore, the probability that the combined value of the four coins randomly selected with replacement will be $.41 is 3/32

Suppose there are two types of tickets to a show: advance and same-day. Advance tickets cost $40 and same-day tickets cost $30. For one performance, there were 65 tickets in all, and the total amount paid for them was $2200. How many tickets of each type were sold?
Answers
Advance tickets: represented by x
Same-day tickets: represented by y
you can model this using a system of equations
x + y = 65
40x + 30y = 2200
then you have to get either the x or y value equivalent in both equations
40(x + y = 65)
40x + 40y = 2600
so the new equations are 40x + 40y = 2600 and 40x + 30y = 2200
then you can solve by using elimination
40x + 40y = 2600
-(40x + 30y = 2200)
10y = 400
y = 40
substitute y back into the first equation
x + 40 = 65
x = 25

It is providing main span of Bridge A is at a 2700 feet and therefore the main span of Bridge B is at a 4300 feet.
Step 1: realize the distinction between the 2 numbers.
4300 - 2700 = 1600
Step 3: Take the magnitude relation of the distinction given by
1600 / 4300
Step 4: Multiply the fraction obtained by a hundred and modify your answer. 1600 / 4300 ×100
