Answer:
37.5
Step-by-step explanation:
Answer: x = 75/2 = 37.5
Step by Step:
Solve for x:
2 x - 16 = 59
Hint: | Isolate terms with x to the left hand side.
Add 16 to both sides:
2 x + (16 - 16) = 16 + 59
Hint: | Look for the difference of two identical terms.
16 - 16 = 0:
2 x = 59 + 16
Hint: | Evaluate 59 + 16.
59 + 16 = 75:
2 x = 75
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 2 x = 75 by 2:
(2 x)/2 = 75/2
Hint: | Any nonzero number divided by itself is one.
2/2 = 1:
Answer: x = 75/2 = 37.5

Gina is training for a marathon. She ran 4.6 miles on Friday and 6.75 miles on Saturday. On Sunday, she ran 13 miles. How much farther did she run on Sunday than she did on Friday and Saturday combined?
Answer:
1.65
Step-by-step explanation:
First you need to find the sun of 4.6 and 6.75, you should do this because it is asking for the two numbers combined. When you add these two numbers, you get 11.35
Now you need to subtract 13 and 11.35 because it wants to know how much father she ran on Saturday than friday, signaling subtraction. When you subtract 13-11.35 you should get 1.65

What is the quadratic regression equation that fits these data
Answer: The objective of this problem is to have you use a calculator and enter the data in to separate lists: one containing the x-values, and the other the correspondent y-values (following the same order). Once the data is entered, you need to access the regression tool and request a quadratic form of regression. You should get and image and resulting function as shown in the attached image.

4x- (3x+2)= 7x-2
What’s the answer?
Answer:
first remove the parrenteses
so from this 4x- (3x+2)= 7x-2
to this 4x- 3x+2= 7x-2
then change the + to a -
so 4x- 3x- 2= 7x-2
then cancel equal terms on both sides of the equation so
4x- 3x= 7x
then collect like terms x =7x
then move the variable to the left hand side and change the sign
x- 7x = 0
next collect like terms
-6x =0
then divide both sides of the eqution by -6
so the awnse is x=0

Rachel rents three DVDs from Watchflicks and two DVDs from Bluechest. The probability that a DVD is faulty is 4% for Watchflicks and 5% for Bluechest. All DVD rentals being faulty or otherwise are independent of each other. Calculate the probability that exactly
Answer:
0.017
Step-by-step explanation:
The probability that exactly some number of DVDs are faulty is approximately 0.9884 or 98.84%.
To calculate the probability that exactly a certain number of DVDs are faulty, we need to use the binomial probability formula. The binomial probability formula is given by: [tex]P(X = k) = C(n, k) * p^k * q^{n-k}[/tex]
- P(X = k) is the probability of getting exactly k successes (in this case, exactly k faulty DVDs).
- C(n, k) is the number of combinations of n items taken k at a time, also known as the binomial coefficient. It is calculated as [tex]C(n, k) = n! / (k! * (n - k)!).[/tex]
- p is the probability of success (getting a faulty DVD from Watchflicks or Bluechest).
- q is the probability of failure (getting a non-faulty DVD), which is equal to 1 - p.
- n is the total number of trials (in this case, the total number of DVDs rented).
Let's calculate the probability that exactly "x" DVDs are faulty (where x can be 0, 1, 2, 3, or 4).
Probability of getting a faulty DVD from Watchflicks (p1) = 4%
= 0.04
Probability of getting a faulty DVD from Bluechest (p2) = 5%
= 0.05
Total number of DVDs rented from Watchflicks (n1) = 3
Total number of DVDs rented from Bluechest (n2) = 2
Total number of DVDs rented (n) = n1 + n2
= 3 + 2
= 5
Let's calculate the probabilities for each value of x:
1. Probability that exactly 0 DVDs are faulty (x = 0):
[tex]P(X = 0) = C(5, 0) * (0.04)^0 * (1 - 0.04)^5 \\= 1 * 1 * 0.961^5 \\\approx 0.8145[/tex]
2. Probability that exactly 1 DVD is faulty (x = 1):
[tex]P(X = 1) = C(5, 1) * (0.04)^1 * (1 - 0.04)^4 \\= 5 * 0.04 * 0.960^4 \\\approx 0.1641[/tex]
3. Probability that exactly 2 DVDs are faulty (x = 2):
[tex]P(X = 2) = C(5, 2) * (0.04)^2 * (1 - 0.04)^3 \\= 10 * 0.0016 * 0.941^3 \\\approx0.0084[/tex]
4. Probability that exactly 3 DVDs are faulty (x = 3):
[tex]P(X = 3) = C(5, 3) * (0.04)^3 * (1 - 0.04)^2 \\= 10 * 0.000064 * 0.922^2\\ \approx0.0014[/tex]
5. Probability that exactly 4 DVDs are faulty (x = 4):
[tex]P(X = 4) = C(5, 4) * (0.04)^4 * (1 - 0.04)^1 \\= 5 * 0.00000256 * 0.960 \\\approx 0.0000024[/tex]
Now, to find the probability that "exactly" (all DVDs being accounted for) a certain number of DVDs are faulty, we simply add up the individual probabilities: P(exactly 0 DVDs faulty) + P(exactly 1 DVD faulty) + P(exactly 2 DVDs faulty) + P(exactly 3 DVDs faulty) + P(exactly 4 DVDs faulty) ≈ 0.8145 + 0.1641 + 0.0084 + 0.0014 + 0.0000024
≈ 0.9884

Given h(x)=-5x+1, solve for a when h(x) = - 4 .
Answer:
x = 1
Step-by-step explanation:
h(x) = - 5x + 1, h(x) = - 4
- 4 = - 5x + 1
- 5 = - 5x
x = 1
If we solve for the value of x in function h(x) = -5x + 1 where , h(x) = -4 , then it will be equal to 1.
What is a function ?
A function is a relationship between inputs and outputs where each input has precisely one output and the output can be linked to its input.
It is given that the function h(x) is given by :
h(x) = -5x + 1
We have to solve to get the value of x , if the value of h(x) is equal to -4.
So , let's solve the given function to get the value of x :
h(x) = -5x + 1
or
-4 = -5x + 1
reordering the like terms :
-5 = -5x
dividing by 5 on both sides :
-1 = -x
multiplying by -1 on both sides :
x = 1
Therefore , if we solve for the value of x in function h(x) = -5x + 1 where , h(x) = -4 , then it will be equal to 1.

Answer:
Step-by-step explanation:
The formula for the area of a rectangle is [tex]area=w*l[/tex] , where w is the width of the rectangle and l is the length of the rectangle.
The question tells us that the length is four times it width. This means that [tex]l=4w[/tex] . Since we are given the length, 4w, and the area, 256, we can plug in these values into our formula for area of a rectangle and solve for the width:
[tex]256=w*4w[/tex]
[tex]w^2=\frac{256}{4}[/tex]
[tex]w=\sqrt{64} =8[/tex]
The width of the rectangle is 8 centimeters.
Now that we have the width of the rectangle, we can plug that value into our original equation again to solve for the width:
[tex]256 = 8 * l[/tex]
[tex]l=32[/tex]
The length of the rectangle is 32 centimeters.
If you bought a stock last year for a price of $59, and it has risen 13% since then, how much is the stock worth now, to the nearest cent?
Answer:
It will be 66.67 but if we estimate to the nearest tenth It will be 66.7
The stock is currently worth $66.67.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To find the current value of the stock, we need to multiply its original price by the percentage increase:
Current value = Original price x (1 + Percentage increase)
Percentage increase.
= 13%
= 0.13 (since percentages are decimals)
Original price = $59
So,
The current value of the stock is:
Current value.
= $59 x (1 + 0.13)
= $59 x 1.13
= $66.67 (rounded to the nearest cent)
Therefore,
The stock is currently worth $66.67.
