What is the mode? -5 0 -9 0 0 -9
The mode for this question is 0
ModeIn a set of numbers, the mode is the number that occurs most often. In other words, it measures how frequently a particular number occurs within a set of numbers. It is a type of average, like its counterparts, the median and mean.
To find the mode of a set of numbers,
List the set of numbers in ascending or descending order, including any duplicatesCount the number of times each number in the set of numbers occurs. The number that occurs the highest number of times is the mode of the set of dataA point located at (-5, -6) is reflected over the x-axis
(-5,6)
Step-by-step explanation:When a point is reflection a new, prime point (x') is created.
Formula
Whenever a point is reflected over the x-axis it follows a specific rule. The point goes from (x,y) to (x,-y). So, since the point is (-5, -6) we need to switch the sign of the y-value. This creates the new point (-5, 6).
Why?
Another way to remember this formula is to understand where it comes from. When reflecting over the y-axis, a point goes from the top 2 quadrants to the bottom 2 or vice versa. This means that the value is moving vertically. During vertical shifts, there is a change in the y-value. Additionally, because the x-axis is the seperation between negative and positive y-values, the y-value changes signs.

The angles in a quadrilateral are 4y - 10°, y + 40°, 3y + 20° and 2y + 10° in order as you go around the quadrilateral.
a) Set up and solve an equation, to find the value of y.
b) Hence work out the value of each angle.
c) What type of quadrilateral is this?
Answer:
see explanation
Step-by-step explanation:
the sum of the interior angles of a quadrilateral = 360°
sum the 4 angles and equate to 360
4y - 10 + y + 40 + 3y + 20 + 2y + 10 = 360 , that is
10y + 60 = 360 ( subtract 60 from both sides )
10y = 300 ( divide both sides by 10 )
y = 30
then 4 angles are
4y - 10 = 4(30) - 10 = 120 - 10 = 110°
y + 40 = 30 + 40 = 70°
3y + 20 = 3(30) + 20 = 90 + 20 = 110°
2y + 10 = 2(30) + 10 = 60 + 10 = 70°
Since the angles measures are in order around the quadrilateral, then
the opposite angles are congruent, thus quadrilateral is a parallelogram

∘
∘
. How tall is the tree if the point on the ground is 53 feet from the tree? Round your answer to the nearest hundredth of a foot if necessary.
Answer:60.97
Step-by-step explanation: tan 49 = opposite/adjacent = x/53
tan 49 = x/53
tan 49/1 = x/53
53 tan 49 = x
x = 60.969
x = 60.97
The height of tree is 60.97 feet tall on the ground is 53 feet from the tree.
What is a trigonometric function?Trigonometry uses the first six fundamental trigonometric functions. Trigonometric proportions are these functions. The six fundamental trigonometric functions are the sin function, cosine function, secant function, and so on.
As per the data given in the question,
tan 49° = opposite/adjacent
tan 49° = x/53
tan 49/1 = x/53
x = 53 tan 49°
x = 60.969 or,
x = 60.97 feet. (rounding off value)

(a) How many miles did Chloe travel from time t = 0 to time t = 2 ?
Do not write beyond this border.
Do not write beyond this border.
Answer:
Step-by-step explanation:
a) ∫from 0 to 2 of te^(4-t^2) dt. Let u = 4-t^2. du= -2dt. And, tdt= -dy/2.
If x=0, u= 4 and if x=2, u=0.
Therefore our new integral will be, -(1/2) ∫ from 0 to 4 of e^u du.
= -(1/2)(e^u) | 0 to 4
= -(1/2)(e^0 - e^4)
= -(1/2) + (1/2)e^4
= (1/2)(e^4 -1) miles
Therefore, from t=0 to t=2, Chloe has travelled a distance of (1/2)(e^4-1) miles.
b) At t=3, C(t)=12-3t-t^2
C(t) is already a function of velocity so simply plug in C(3), which is -6 miles/hour.
We also need to know acceleration.
C'(t)= -3 - 2t
C(3)= - 9 miles/hour squared.
Therefore, since velocity and acceleration are both negative, Chloes speed is increasing at t =3 hours.

Determine whether F(x)=4x^2-16x+6 has a maximum or a minimum value and find that value
Answer:
f(x) has a minimum value of -10.
Step-by-step explanation:
It will have a minimum value because the coefficient of x^2 is positive.
To find its value we convert to vertex form:
f(x) = 4x^2 - 16x + 6
= 4(x^2 - 4x) + 6
= 4[(x - 2)^2 - 4] + 6
= 4(x - 2)^2 - 16 + 6
= 4(x - 2)^2 - 10.
So the minimum value is -10.

A two-sided test of H0: μ=0, α=0.05 (two sided), yields a p-value of 0.19. Will the 95% confidence interval for μ include 0?
Group of answer choices
No
Unknown
Yes
Explanation
Rule: if the p-value is smaller than alpha, then we reject the null.
We're given a p-value of 0.19 and alpha = 0.05
Based on that rule, it means we fail to reject the null (i.e. "accept" the null), since the p-value is not smaller than alpha.
Therefore, we conclude that mu = 0 must be the case, which means this value is in the confidence interval.
If mu = 0 was outside the confidence interval, then we would reject the null.

Graph B represents j(x).
From the question, we have the following parameters:
h(x) = f(x) + g(x)
j(x) = f(x) * g(x)
As, we don't have function of the graphs.
So, all the functions are linear functions, then the slopes of the sum of functions f(x) and g(x) could be greater than the slopes of h(x) and j(x).
