(4, 5)remain constant and increaseg(x) exceeds the value of f(x)What is Slope and curve?a) The slope of the curve g(x) roughly matches that of f(x) at about x=4. Above that point, the curve g(x) is steeper than f(x), so its average rate of change will exceed that of f(x). An appropriate choice of interval is (4, 5).
b) As x increases, the slope of f(x) remains constant (equal to 4). The slope of g(x) keeps increasing as x increases. An appropriate choice of rate of change descriptors is (remain constant and increase).
c) The curves are not shown in the problem statement for x = 8. The graph below shows that g(x) has already exceeded f(x) by x=7. It remains higher than f(x) for all values of x more than that. We can also evaluate the functions to see which is greater:
f(8) = 4·8 +3 = 35
g(8) = (5/3)^8 ≈ 59.54 . . . . this is greater than 35
g(8) > f(8)
d) Realizing that an exponential function with a base greater than 1 will have increasing slope throughout its domain, it seems reasonable to speculate that it will always eventually exceed any linear function (or any polynomial function, for that matter).

What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The total number of people who were surveyed are:
Total Number of people = 82 + 94 +18 + 46 + 48 + 91 = 379
Also, it is mentioned in the table that the number of females who prefers suspense movies is 18. Therefore, the probability that a person will be a female and prefer suspense movies will be,
[tex]\rm Probability = \dfrac{\text{Number of females who prefers suspense movies}}{\text{Total Number of people}}\\\\Probability = \dfrac{18}{379} = 0.047[/tex]

g True or false: For continuous random variables, the probability of being less than some value, x, IS NOT the same as the probability of being less than or equal to the same value, x. Group of answer choices True False
===========================================================
Explanation:
The given statement is claiming something like [tex]P(X < 2)[/tex] produces a different result compared to [tex]P(X \le 2)[/tex]. The subtle difference of course is the "or equal to".
When talking about continuous random variables, the two values are the same. Why? Because probability of selecting *exactly* X = 2 is going to be zero. Think of a very very thin strip of height P(X = 2) and the width is approaching zero. The width is doing this because we're trying to pinpoint X = 2 itself. As you can see, this skinny rectangle will have its area approach 0. Ultimately, whether we compute [tex]P(X < 2)[/tex] or [tex]P(X \le 2)[/tex], it doesn't matter. They both produce the same result.
If you are a visual learner, consider the standard normal distribution. Now consider the task if shading to the left of z = 2. This area describes both probabiltiies mentioned above.
If X is a continuous random variable, then [tex]P(X < 2) = P(X \le 2)[/tex] and we can change the "2" to any number we want to have the same outcome.
Therefore, the original claim is false.
-------------------------
Extra info:
Now if X was discrete (say from the binomial distribution), then the two probabilities would be different. This is because
[tex]P(X < 2) = P(0) + P(1)\\\\P(X \le 2) = P(0) + P(1) + P(2)\\\\P(X < 2) \ne P(X \le 2) \ \text{only if X is discrete}[/tex]
We can see in this case that the second line has P(2) while the first one does not.
So the original claim would be true if we changed "continuous" to "discrete".

After a heavy rainstorm, Barbara's dog left muddy paw prints all over her back patio. She decided to rent an electric
pressure washer to clean up the mess. The piecewise function below shows the rental charges for the pressure

$15.00
O $41.00

$61.00
Answer:
$15.00
Step-by-step explanation:
Just did the quiz
By evaluating the piecewise function, we will see that the brother owes $15.
How much does her brother owe her?
The piecewise function is:
y = 26, if 0 < h < 4
y = 26 + 5*(h - 4), if 4 < h < 8
y = 60, if 8 < h
Barbara uses it for 3 hours, so we only need to use the first part for her, so she needs to pay $26.
Then the brother uses it for 4 hours (and we need to add the 3 hours that Barbara used it, so we have h = 7).
Then for the 7 hours the two brothers need to pay:
y = $26 + $5*(7 - 4) = $41
If we subtract the part that Barbara needs to pay we get.
$41 - $26 = $15
This means that the correct option is $15.

Kyle competes in 100 m wheelchair races. Hel
calculates the information below using his last 4
race times.
His minimum race time was 19.8 s.
The range of his race times was 5.6 s.
The median of his race times was 23.8 s.
The mode of his race times was 25.4 s.
If Kyle includes a new race time of 25.7 s in his
calculations, how much will the mean change
by?
Answer:
0.5s
Step-by-step explanation:
His initial mean would be calculated by:
His minimum race time = 19.8s
The maximum race time = 19.8 + 5.6 = 25.4s
Since the mode is also 25.4, there are 2 25.4s races.
Since the median is 23.8s and the number of race times is even, the final race time can be calculated by:
25.4- 23.8s = 1.6s
23.8-1.6 = 22.2s
So the race times are 19.8s, 22.2s, 25.4s and 25.4s.
This means that his initial mean was (19.8+22.2+25.4+25.4)/4 = (42+50.8)/4= 92.8 /4 = 23.2s
With the new race time, the equation will change to (92.8+25.7)/(4+1)= 118.5/5= 23.7s
So the mean change would be 23.7 - 23.2 = 0.5 s.
Hope this helps!
Solve x: -7y=2x+xy+10y
Answer:

Anna ordered a large pizza with 2 toppings. What was the total cost of her pizza? Show your equation and the total cost.
Answer: $15.49.
Step-by-step explanation: So far, her pizza already costs $13.99 because she chose large. However, she also ordered two toppings for $0.75 each, which is $1.50. We need to add $13.99 and $1.50 to find out the total cost of her custom pizza.
$13.99 + $1.50 = $15.49.
Therefore, the total cost of her pizza is $15.49.

Answer:

Step-by-step explanation:
[tex](-1 (\frac{2}{3} - 4)) / (5/6)[/tex]
Let's solve for the numerator first:
PEMDAS says parenthesis first so...
2/3 - 4, we'll turn 4 into an improper fraction so it's easier
2/3 - 12/3 = -10/3
-1(-10/3) = (+)10/3
Now, we replace this as the numerator:
(10/3) / (5/6)
To divide, we multiply the first fraction by the reciprocal of the second:
(10/3) * (6/5) = 60/15
now simplify.....
60/15 = 4 or in other words, {15 * 4 = 60}
So, the answer is 4!

The line of best fit shows that Luther can expect the speed to be 51 miles/hour when he throws 80 pitches and 64 miles/hour when he throws 54 pitches.
How to calculate the speed?The average speed of Luther's pitches when he throws 80 pitches will be:
y = -0.511x + 91.636
= -0.511(80) + 91.636
= 50.756
= 51
Also, the number of pitches that Luther can throw when the speed is 64 miles per hour will be:
y = -0.511x + 91.638
64 = -0.511x + 91.638
0.511x = 91.638 - 64
0.511x = 27.636
x = 54
