Describe the graph of the solution to the inequality 8x + 17 ≥ 137
Answers
Answer:
Simplifying
8x + 17 = 137
Reorder the terms:
17 + 8x = 137
Solving
17 + 8x = 137
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-17' to each side of the equation.
17 + -17 + 8x = 137 + -17
Combine like terms: 17 + -17 = 0
0 + 8x = 137 + -17
8x = 137 + -17
Combine like terms: 137 + -17 = 120
8x = 120
Divide each side by '8'.
x = 15
Simplifying
x = 15

A quality-conscious disk manufacturer wishes to know the fraction of disks his company makes which are defective. Step 1 of 2: Suppose a sample of 542 floppy disks is drawn. Of these disks, 37 were defective. Using the data, estimate the proportion of disks which are defective. Enter your answer as a fraction or a decimal number rounded to three decimal places.
Answers
Answer:
0.068 or 6.826%
Step-by-step explanation:
In order to calculate the proportion of disks that are defective, we need to divide the number of defective disks by the total amount of disks that were chosen in the given sample. Using the data provided this would be the following calculation...
37 / 542 = 0.068
We can multiply this by 100 to get the percentage value
0.068 * 100 = 6.826%
Therefore, roughly 6.826% of the entire disk population would be defective.
6. The angle of elevation from a small boat to the top of a lighthouse is 25°. If the top of the lighthouse is 150
feet above sea level, find the distance from the boat to the base of the lighthouse.
Answers
Answer:
321.68feet
Step-by-step explanation:
Given the following
Top of the house above the sea level = 150feet = opposite
Angle of elevation = 25°
Required
Distance from the boat to the base of the house(adjacent)
Using the SOH CAH TOA identity
tan theta = opp/adj
tan 25 = 150/d
d = 150/tan25
d = 150/0.4663
d = 321.68
Hence the required distance is 321.68feet

Which shape of distribution would typically have the smallest standard deviation?
normal distribution
uniform distribution
skewed left distribution
skewed right distribution
Answers
Answer:
The shape that has the smallest standard deviation is;
Uniform distribution
Step-by-step explanation:
A uniform distribution is a probability distribution where the outcomes are equally likely such as the probability of landing any face of a die, or the probability of landing a head or a tail, or a perfect random number distribution
Therefore, the outcome of a uniform distribution are all the same and the standard deviation is zero (0)
Therefore, the uniform distribution has the smallest standard deviation.

What is the inverse of the function f(x) = x +3? 1 O h(x) = = x + 3 3 5x+3 = Oh(x) = rx - 3 3 Oh(x) = x-3 O h(x) = x + 3
Answers
Answer:
C
Step-by-step explanation:
the inverse of x+3 is x-3
The value of the inverse of the function f(x) = x +3 is,
⇒ h (x) = x - 3
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The function is,
⇒ f (x)= x + 3
Now, We can find the inverse function as;
⇒ f (x) = x + 3
⇒ y = x + 3
Solve for x;
⇒ x = y - 3
Substitute y = x and x = h (x);
⇒ h (x) = x - 3
Thus, The value of the inverse of the function f(x) = x +3 is,
⇒ h (x) = x - 3

A department store offers free samples of a 2-ounce
container of lotion with every fragrance purchase. Write a
rule to describe the number of ounces of product for each
purchase. Plot 3 points on the graph to show the pattern.
Use t for the total number of ounces and ffor the ounces
of fragrance.
Answers
Answer:
The situation you are describing can be written as y=2x, or in this case t=2f, for every fragrance purchased there are 2 ounces of lotion that are given. Since the ounces of fragrance are not shown in this question, we can only make the graph on the ounces of lotion for every fragarance purchased. The points of the graph represent that for every fragrance bought, there is twice the amount of that in ounces of lotion. In summary, the rule is t=2f where t would equal purchases of fragrance and f would equal the ounces of lotion.

A trapezoid has base lengths of 20 units and 28 units. The area of the trapezoid is 408 square units. What is the height of the trapezoid?
Answers
Answer:
h = 17 units
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the height and b₁ , b₂ the parallel bases
Here A = 408, b₁ = 20, b₂ = 28 , then
[tex]\frac{1}{2}[/tex] h (20 + 28) = 408 ( multiply both sides by 2 to clear the fraction )
48h = 816 ( divide both sides by 48 )
h = 17

The exponential function is given by f(x) = 7ˣ
Exponential Function
An exponential function is in the form:
y = abˣ
Where a is the initial value of y, b is the multiplier, y and x are variables.
Given the y-intercept is (0,1), hence:
1 = ab⁰
a = 1
Also f(2) = 49, hence:
49 = (1)(b)²
b = 7
The exponential function is given by f(x) = 7ˣ
