Answer:
[tex]x=2.3\text{ only }[/tex]
Step-by-step explanation:
We are given the second derivative:
[tex]g^\prime^\prime(x)=0.1x^5-0.29x^4-0.694x^3+1.9136x^2[/tex]
And we want to find the values for -3 < x < 4 in which the graph of g has a point of inflection where the concavity changes from concave up to down.
First, recall that inflection points occur whenever g''(x) = 0 or is undefined.
And that:
g is concave up for an interval if g''(x) > 0 for that interval. g is concave down for an interval if g''(x) < 0 for that interval.Graphing the function (please refer below for the graph), we can see that g''(x) has an inflection point at x = -2.6, 0, 2.3, and 3.2.
If g''(x) changes from concave up to concave down, the values before and after that inflection point must be positive and then negative.
We can see that g''(x) is only positive for the values before the inflection points at x = 0 and x = 2.3.
However, for values after the inflection points, only x = 2.3 becomes negative.
Therefore, since at x = 2.3, the graph changes from positive to negative, this is where the graph of g changes from concave up to concave down.
Notes:
For the point x = 0, the graph stayed positive both before and after x = 0.
Therefore, g does not have an inflection point at x = 0.

The final margin of an NFL football game is approximately normally distributed, with a mean equal to the gambling point spread and a standard deviation of 14 points. Recall the great 2008 Super Bowl in which the Giants upset the Patriots. The Patriots had been favored by 12 points. What does that fact imply about the Giants' initial (i.e., pre-game) chances of winning
Answers
Answer:
The Giants had 0.1949 = 19.49% probability of winning initially.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean equal to the gambling point spread and a standard deviation of 14 points. The Patriots had been favored by 12 points.
This means that [tex]\mu = 12, \sigma = 14[/tex]
What does that fact imply about the Giants' initial (i.e., pre-game) chances of winning
P(X > 0): Probability of Patriots winning.
P(X < 0): Probability of Giants winning.
So we want to find P(X < 0), which is the pvalue of Z when X = 0. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0 - 12}{14}[/tex]
[tex]Z = -0.86[/tex]
[tex]Z = -0.86[/tex] has a pvalue of 0.1949
The Giants had 0.1949 = 19.49% probability of winning initially.

Answers
Answer:
A) -4
Step-by-step explanation:
There are two ways of solving this:
1.) Plugging in the answer choices
Since the equation needs to be equal to or less than 1 (this is due to the less than or equal to sign: ≤)
You will then set the equation: -2x-6 ≤ 1
You will then take each answer choice and plug it into the original equation.
Plug in -4: -2(-4)-6 ≤ 1 this will result in 2 ≤ 1
Plug in -3: -2(-3)-6 ≤ 1 this will result in 0 ≤ 1
Plug in -2: -2(-2)-6 ≤ 1 this will result in -2 ≤ 1
Plug in -1: -2(-1)-6 ≤ 1 this will result in -4≤ 1
The only one that is not true is when you plug in x=-4 into the equation -2x-6. This results in the equation being equal to 2. 2 is not less than 1, making the equation false.
Method 2: Solving the inequality
You can essentially solve for x like a normal inequality.
Instead of solving for -2x-6 = 1, we are doing -2x-6 ≤ 1.
First: Add 6 to the right side
-2x ≤ 1+6 --->>>> 2x ≤ 7
Second: Divid both sides by -2
***Note: When you divivde by a negative when solving an inequality, you must switch the sign. ***
x ≥ -3.5 (hence the sign swtiches from ≤ to ≥ since we divided by a negative value in the equation)
x ≥ -3.5 states that any number greater or equal to -3.5 will work. -4 is less than -3.5, thus it will not satisfy the inequality.
Oatmeal is made by mixing 15 cups of hot water to 6 cups of oats.
Answers
9514 1404 393
Answer:
2/5 cups oats per cup water2.5 cups water per cup oatsStep-by-step explanation:
The denominator of the fraction is the unit you want 1 of.
(6 cups oats)/(15 cups water) = (6/15) cups oats/(1 cup water)
= (2/5 cups oats)/(1 cup water)
1 cup of water would need 2/5 cups of oats.
__
Obviously, the other ratio is the reciprocal of this.
(1 cup water)/(2/5 cups oats) = (5/2 cups water)/(1 cup oats)
1 cup of oats would need 2.5 cups of water

In the year 2005, there were 100 rabbits in a particular region. Since then, the population has increased by 3.4% per year. Write an expression that represents the rabbit population in the year 2025, and solve it.
Answers
Answer:
Step-by-step explanation:
Your answer
Ok, lets do it systematically.
2005– 100 rabbits
3.4 % per year increasement.
So every year it increase 0.034 *100 = 3.4 per year
Total 2025-2005= 20 years
So expression is : 0.034*100*year(20)
Answer is : 3.4*20 = 68. So, in 2025, total rabbits will be 168

A statue of George Washington is also in Druids a 15 m away from the statue and places a mirror 12 m from the statue (3 m from her feet)she can see the top of the statue in the mirror. The girl's height is How tall is the statue(draw a diagram and solve)
Answers
Answer:

Let 'x' represent the height of the statue.
1 ft = 0.3048 m
5.5 ft = 5.5*0.3048 m
Using the similar triangles we can write:
x : 3 = 12 : (5.5*0.3048)
x = 21.47 m
The statue is 21.47 meters tall

The legs of the drafting table form vertical angles. Find the measures of ∠1, ∠2 and ∠3.
Answers
Answer:
m∡1 = 95°
m∡2 = 85°
m∡3 = 95°
Step-by-step explanation:
m∡1 + 85 = 180; m∡1 = 95°
m∡2 = 85° because it is vertical and congruent to the angle measured 85°
m∡3 = m∡1 = 95° because they are vertical and congruent
Answer:
1 = 95, 2 = 85, 3 = 95
Step-by-step explanation:
2 is an opposite angle of 85 degrees so 2 is 85 degrees
a line is always 180 degrees:
1 = 180 - 85 = 95 degrees
1 is an opposite angle of 3 so 3 is also 95 degrees
