Answer:
54
Step-by-step explanation:
45,776 is exactly 1,000 times bigger than 45.776, as you can move the decimal point in 45.776 three places to the right to match the value of 45,776.
To determine how many times bigger 45,776 is than 45.776, we simply divide the larger number by the smaller number:
First, write down the two numbers: 45,776 and 45.776.Convert 45.776 to the same form as 45,776 by multiplying by 1000 (to move the decimal point three places to the right).The calculation will look like this: 45,776 / (45.776 x 1000) = 45,776 / 45,776 = 1,000.45,776 is 1,000 times bigger than 45.776.

Final answer:
The Quadratic formula will give us the coordinates of the points of intersection of a line and a quadratic only when the value of the discriminant is positive or zero.
Explanation:
The Quadratic formula will give us the coordinates of the points of intersection of a line and a quadratic only when the value of the discriminant is positive or zero.
The quadratic formula is:
x = (-b ± √(b² -4ac)) / 2a
Where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0.
The quadratic formula will give us the coordinates of the points of intersection of a line and a quadratic only when the value of the discriminant is positive or zero. The quadratic formula is derived from the standard form of a quadratic equation, which is ax² + bx + c = 0. To find the points of intersection between a line and a quadratic, we would substitute the y-component (or x-component, depending on the variable used) of the line equation into the quadratic equation and solve for the remaining variable using the quadratic formula.

9. Find the vertex of f(x) = –2x2 - 4x – 8
a. Vertex: (-1,-6) b. Vertex: (-6,-1) C. Vertex: (2,1)
d. Vertex: (1,6)
e. Vertex: (1,-6)
Answer:
A is the answer, (-1,-6) is the vertex.
Step-by-step explanation:
With any quadratic, the formula for the x coordinate of the vertex is -b/2a.

Which of the following is true of the data represented by the box plot?
box plot with point at 15, min at 17, Q1 at 51, median at 65, Q3 at 74, max at 90
A) If the outlier is included in the data, the median would not significantly change.
B) If the outlier is included in the data, the mean would increase.
C) If the outlier is included in the data, the box plot would be significantly skewed.
D) If the outlier is included in the data, the length of the tails would change significantly.
Answer:
the outlier is the point at 15
the data is skewed to the bottom because the values below the median are far more spread out; there are more extreme values that are far below the median than above the median.
Step-by-step explanation:
A) If the outlier is included in the data, the median would not significantly change.
Box Plot is a pictorial way of denoting data's distribution on the basis of Quartile 1, Quartile 3, Minimum, Median and Maximum
Outliers are the data observations or points, lying at huge significant difference (distance) from other concentrated data observation points.
A data value below the Box Plot Minimum, or above the Box Plot Maximum is an Outlier.Median is a Positional average, the mid point of data. It divides the data into two equal halves, 50% below it & 50% above it.
Median is not effected by extreme values like Outliers. So, inclusion of outliers doesn't significantly change Median.Mean is an Arithmetic Average. It is effected by extreme values like outliers. However, in this case of presence of Lower Outlier, the mean would decrease rather than increasing.
Skewness or Tail in the data denotes concentration of values in either (lower or higher side). It is not related to outliers.

Find the surface area of the pyramid shown below. The base is a rectangle and the opposite
triangular faces are the same size and shape.
Answer:
SA = 397
Step-by-step explanation:
The area of the rectangle is L x W = 18 x 7 = 126
The area of the triangle[tex]\frac{1}{3}[/tex] face is
A = [tex]\frac{1}{2}[/tex]bh
A = [tex]\frac{1}{2}[/tex] 18 x 10
A = [tex]\frac{1}{2}[/tex] 180
A = 90
Since there are two triangles the same size we times by 2
90 x 2 = 180
The triangles on the left and right sides are two other sizes compared to the other two triangles
A = [tex]\frac{1}{2}[/tex]bh
A = [tex]\frac{1}{2}[/tex] 7 x 13
A = [tex]\frac{1}{2}[/tex] 91
A = 45.5
Since there are two triangles the same size we times by 2 again so it will be 91
Than we add them up
91 + 126 + 180 = 397

Step-by-step explanation:
Ahmed is riding the elevator in a building. The building has floors above and below ground level. Ahmed uses the expression below to describe his movement.
6 + (negative 8)
Which statement could describe Ahmed’s movement?
Final answer:
Ahmed's movement described by the expression 6 + (negative 8) suggests he moves from the sixth floor above ground level down to the second floor below ground level.
Explanation:
The expression Ahmed uses to describe his movement in the elevator is 6 + (negative 8). To understand this expression in the context of elevator movement, 6 could represent Ahmed starting on the sixth floor above ground level. The addition of negative 8 would signify moving 8 floors downward. Thus, the expression indicates that Ahmed moves from the sixth floor down to the second floor below ground level (since 6 - 8 equals -2). The negative result corresponds to floors below ground level. Therefore, the statement that could describe Ahmed's movement is: Ahmed moves from the sixth floor above ground level down to the second floor below ground level.

In a data set with a normal distribution, the mean is 59 and the standard deviation is 3.
Part A
About what percent of the data lie between 53 and 62?
A. 68%
B. 83.85%
C. 81.5%
D. 50%
Part B
Complete: About 95% of the data lie between
Answer:
a) [tex]P(53<X<62)=P(\frac{53-\mu}{\sigma}<\frac{X-\mu}{\sigma}<\frac{62-\mu}{\sigma})=P(\frac{53-59}{3}<Z<\frac{62-59}{3})=P(-2<z<2)[/tex]
[tex]P(-2<z<2)=P(z<2)-P(z<-2)[/tex]
[tex]P(-2<z<2)=P(z<2)-P(z<-2)=0.97725-0.02275=0.9545[/tex]
b) [tex]a=59 +1.96*3=64.88[/tex]
And for the other limit we have:
[tex]a=59 -1.96*3=53.12[/tex]
And we will have 95% of the values between (53.12, 64.88)
Step-by-step explanation:
Part a
Let X the random variable of interest of a population, and for this case we know the distribution for X is given by:
[tex]X \sim N(59,3)[/tex]
Where [tex]\mu=59[/tex] and [tex]\sigma=3[/tex]
We are interested on this probability :
[tex]P(53<X<62)[/tex]
And we can solve this using the z score:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
Using the last formula we got:
[tex]P(53<X<62)=P(\frac{53-\mu}{\sigma}<\frac{X-\mu}{\sigma}<\frac{62-\mu}{\sigma})=P(\frac{53-59}{3}<Z<\frac{62-59}{3})=P(-2<z<2)[/tex]
And we can find this probability with this difference:
[tex]P(-2<z<2)=P(z<2)-P(z<-2)[/tex]
And uing the normal standard distribution or excel we got:
[tex]P(-2<z<2)=P(z<2)-P(z<-2)=0.97725-0.02275=0.9545[/tex]
Part b
For this part we want to find a value a, such that we satisfy this condition:
[tex]P(X>a)=0.025[/tex] (a)
[tex]P(X<a)=0.975[/tex] (b)
As we can see on the figure attached the z value that satisfy the condition with 0.95 of the area on the left and 0.05 of the area on the right it's z=1.96.
If we use condition (b) from previous we have this:
[tex]P(X<a)=P(\frac{X-\mu}{\sigma}<\frac{a-\mu}{\sigma})=0.975[/tex]
[tex]P(z<\frac{a-\mu}{\sigma})=0.975[/tex]
But we know which value of z satisfy the previous equation so then we can do this:
[tex]z=1.96<\frac{a-59}{3}[/tex]
And if we solve for a we got
[tex]a=59 +1.96*3=64.88[/tex]
And for the other limit we have:
[tex]a=59 -1.96*3=53.12[/tex]
And we will have 95% of the values between (53.12, 64.88)
In a normal distribution with mean 59 and standard deviation 3, approximately 81.85% of the data lie between 53 and 62. And about 95% of the data lie between 53 and 65, which is two standard deviations from the mean.
Explanation:In a normal distribution, about 68% of the data lie within one standard deviation of the mean, about 95% lie within two standard deviations, and about 99.7% within three standard deviations.
Part A:
The range from 53 to 62 in this case is from -2 standard deviations from the mean (56) to +1 standard deviation (62). Looking at the empirical rule, we find that about 34.13% of data fall between the mean and -1 standard deviation, and 13.59% fall between -1 and -2 standard deviations. Similarly, about 34.13% of the data fall between the mean and +1 standard deviation. Therefore, the total percentage of data lying between 53 and 62 would be
34.13% + 13.59% + 34.13% = 81.85%, so option B is the closest.
Part B:
About 95% of the data lie between two standard deviations from the mean. Therefore, you would add and subtract two times the standard deviation from the mean, which would yield 59 - 2(3) = 53 and 59 + 2(3) = 65. Thus, about 95% of the data lie between 53 and 65.
