based on the graphic, what can be inferred about the relationship between braking distance and tread depth of tires ?
Answer: A
Step-by-step explanation:
Consider the function.
f(x)=2 1/2 - 3 1/3
What is the x-intercept of f-1(x)?
o (-3 1/3,0)
o (-3/10,0)
o (3/4,0)
o (2 1/2,0)
Answer:
Option 4
Step-by-step explanation:
Given function is,
[tex]f(x)=2\frac{1}{2}-3\frac{1}{3}x[/tex]
Steps to get the inverse of the given function,
Step 1,
Convert the function into equation,
[tex]y=2\frac{1}{2}-3\frac{1}{3}x[/tex]
Step 2,
Interchange the variables 'x' and 'y',
[tex]x=2\frac{1}{2}-3\frac{1}{3}y[/tex]
Step 3,
Solve the equation for the value of y,
[tex]x-2\frac{1}{2}=-3\frac{1}{3}y[/tex]
[tex]x-\frac{5}{2}=-\frac{10}{3}y[/tex]
[tex]-x+\frac{5}{2}=\frac{10}{3}y[/tex]
[tex]-3x+\frac{15}{2}=10y[/tex]
[tex]-\frac{3}{10}x+\frac{15}{20}=y[/tex]
[tex]y=-\frac{3}{10}x+\frac{3}{4}[/tex]
Step 4,
Convert the equation into inverse function,
[tex]f^{-1}x=-\frac{3}{10}x+\frac{3}{4}[/tex]
For x-intercepts,
Substitute y = 0,
[tex]0=-\frac{3}{10}x+\frac{3}{4}[/tex]
[tex]\frac{3}{10}x=\frac{3}{4}[/tex]
[tex]x=\frac{10}{4}[/tex]
[tex]x=\frac{5}{2}[/tex]
[tex]x=2\frac{1}{2}[/tex]
Therefore, x-intercept of the inverse function is [tex](2\frac{1}{2},0)[/tex].
Option 4 will be the answer.
Please help i need the MAD what ever that means
Answer:
what is the MAD??????????
Step-by-step explanation:
Answer:
Answer depends on the data (not provided in your question)
Step-by-step explanation:
MAD stands for mean absolute deviation. The definition gives clues as to how to find it.
Deviation refers to how far a number is from the mean (average) of the data
Example: For the data -12, 4, 12, 16, the mean of the data is (-12+4+12+16)/4 = 5.
Data Absolute Deviation from mean
-12 |-12 - 5| = 17
4 |4 - 5| = 1
12 |12 - 5| = 7
16 |16 - 5| = 11
Mean Absolute Deviation (MAD)
(17 + 1 + 7 + 11) / 4 = 9

Step-by-step explanation:
When the absolute value is bigger with a (-) negative sign, it means that it is the smallest. Since -13.5 has the greatest absolute value with a negative sign, then -3.2 is smaller than 0, the answer is H.

Answer:
[tex]x[/tex] rounded to the nearest integer would be 12.
Step-by-step explanation:
In order to calculate the length of [tex]x[/tex], you can use the law of sines, a trigonometry rule used to solve the angles and sides of a right triangle. The law of sines states that the sine of an angle in a triangle divided by its opposite side is equivalent to all other angles taken to their sines and divided by their opposite sides. Using this rule, we can now calculate the length of [tex]x[/tex]. In this case, [tex]\frac{sin(90^{o})}{15} = \frac{sin(53^{o})}{x}[/tex] ⇒ [tex]\frac{15}{sin(90^{o})} = \frac{x}{sin(53^{o})}[/tex] ⇒ [tex]x=\frac{15*sin(53^{o})}{sin(90^{o})}[/tex] ⇒ [tex]x=15*sin(53^{o} )[/tex] ⇒ [tex]x[/tex] ≈ 12. So side [tex]x[/tex] rounded to the nearest integer would be 12.
The value of x in the given triangle is 12, Option C is correct.
The given triangle is a right angled triangle.
We need to find the value of x.
We know that cosx is adjacent side by hypotenuse.
Cos 37 = Adjacent side/ Hypotenuse

Identify the null and alternative hypothesis in the following scenario.
To determine if battery 1 lasts longer than battery 2, the mean lasting times, of the two competing batteries are compared. Twenty batteries of each type are randomly sampled and tested. Both populations have normal distributions with unknown standard deviations.
a. H0:μ1≥μ2; Ha:μ1<μ2
b. H0:μ1≤−μ2; Ha:μ1>−μ2
c. H0:μ1≥−μ2; Ha:μ1<−μ2
d. H0:μ1=μ2; Ha:μ1≠μ2
e. H0:μ1≤μ2; Ha:μ1>μ2
Answer:
H0 : u1 = u2 ; H1 : u1 ≠ u2 , or specifically u1 > u2
Step-by-step explanation:
Null Hypothesis is the neutral hypothesis , stating no difference from assumed value, (or in this case no difference between both batteries' mean life)
Alternate Hypothesis is the special case hypothesis, stating difference from assumed value , (or in this case states difference between both batteries' mean life)
Let mean life of battery 1 & battery be b = u1 & u2 , respectively.
Null Hypothesis [ H0 ] : u1 = u2
Alternate Hypothesis [ H1 ] : u1 ≠ u2 , or specifically u1 > u2 { To determine if battery 1 lasts longer than battery 2 }

Keri pours 6 glasses of juice. Each glass holds 34 cup. How many cups of juice does Keri pour?
Answer:
3/4x6=4.5
Step-by-step explanation:
If Keri pours 6 glasses that each contain 3/4 cups than If she where to pour all of them than It would be 3/4*6 to represent the amount of cups to glasses and then the answer would be 4.5 C.
In all glasses combined their will be 4.5 cups of water!
Fractions are written as a ratio of two integers. If Keri pours 6 glasses of juice, she must have poured 4.5 cups of juice
Ratio and proportions
Fractions are written as a ratio of two integers.
If Keri pours 6 glasses of juice and each glass contains 3/4 cup, hence the total cups of juice poured is expressed as:
Total cups of juice poured = 3/4 * 6
Total cups of juice poured = 4.5
Hence if Keri pours 6 glasses of juice, she must have poured 4.5 cups of juice

The number of hours, t, that bacteria spread 10-fold can be modeled by the equation B(t) = B0(10)4t. There are 50 bacteria present initially and a biologist wishes to find out how many hours will elapse until there are 10,000 bacteria present. What is the exact value for the number of hours elapsed, t, in the equation 10,000 = 50(10)4t?
Answer:
t = (log200)/4 hours
Step-by-step explanation:
10,000 = 50(10)^(4t)
Divide both sides by 50
200 = 10^(4t)
Take the log of both sides
log200 = 4t
Divide both sides by 4
(log200)/4 = t
t = (log200)/4 (exact answer)
t ≈ 0.575257498915995 (numeric approximation)

We are given the height (H) of the prism = 9 m
Let's find the base area using the figure of the base that is shown above with the dimensions:
Base area = ½*bh

h = 4 m
Base area = ½*14*4
= 28 m²

Your mother has a new cell phone. It comes with 18 apps already installed. She only uses 2/3 of those apps. She downloaded 12 more apps that she uses frequently. Write an equation to represent the total number apps your mom uses.
Answer:
Step-by-step explanation:
The cell phone comes with 18 apps already installed, but she only uses 2/3 of the apps. Therefore, we need to find 2/3 of 18 to find the number of apps she uses. 2/3 * 18 = 12 apps she uses frequently. Outside of that, she downloads 12 more frequently used apps, so you add 12 to 12 to get 24 total apps that she uses.
However, the question asks for the equation to find the answer. So, the equation would be like:
18(2/3) + 12 = x
where x is representing the number of apps she uses.

Quadratic Equations
A quadratic equation is one of the form ax2 + bx + c = 0, where a, b, and c are numbers, and a is not equal to 0.
Factoring
This approach to solving equations is based on the fact that if the product of two quantities is zero, then at least one of the quantities must be zero. In other words, if a*b = 0, then either a = 0, or b = 0, or both. For more on factoring polynomials, see the review section P.3 (p.26) of the text.

2x2 - 5x - 12 = 0.
(2x + 3)(x - 4) = 0.
2x + 3 = 0 or x - 4 = 0.
x = -3/2, or x = 4.

Question:
Two rectangular picture frames have the same area of 45 square inches but have different side lengths. Frame A has a length of 6 3/4 inches, and Frame B has a length of 7 1/2 inches.
Answer:
1. the longer frame (B) has the shorter width
2. the shorter width is 6 3/7 inches, area divided by length
Step-by-step explanation:
The relation between area, length, and width is ...
A = LW
Then the width is ...
W = A/L . . . . . inversely proportional to length
1. Since length and width are inversely proportional (when area is constant), the shorter width will be associated with the longer length. Frame B will have the shorter width.__
2. The width of frame B is ...
W = A/L = (45 in²)/(7 in) = 45/7 in = 6 3/7 in
