Step-by-step explanation:
After examining a child at his 2-year checkup, the boy's pediatrician said that the z-score for his height relative to other 2-year-olds in the country was 1.59. The pediatrician explains to the parents that the most extreme 5% of cases often require special treatment or attention. a) Does this child fall into that group? b) What do you need to assume about the heights of 2-year-olds to find your answer to part a? a) The child _______into this group because he is___________than_______ standard deviation from the mean.b) Choose al that apply. A. the distribution of heights is skewed B. the heights are independent C. the distribution of heights is symmetric D. the number of heights is very large E. the distribution of heights is unimodal
a)The child falls into the most extreme 5% group, we need to compare the z-score of 1.59 to the critical value for the 5th percentile.
b)The information to make assumptions about the skewness, symmetry, or the number of heights is not provided.
A z-score of 1.59 means that the child's height is 1.59 standard deviations above the mean height for 2-year-olds. To decide if the child falls into the most extreme 5% group, we need to find the critical value for the 5th percentile. The critical value corresponds to the z-score that separates the lowest 5% of the distribution from the rest.
b) To find the answer to part a we need to assume certain properties about the heights of 2-year-olds:
A. The distribution of heights is skewed - Skewness is not mentioned in the problem, so we cannot assume the distribution is skewed or not skewed based on the given information.
B. The heights are independent - The heights of 2-year-olds are independent in the sense that one child's height does not influence or depend on another child's height. This is a reasonable assumption in most cases.
C. The distribution of heights is symmetric - The given z-score doesn't tell us directly about the symmetry of the distribution, so we cannot assume the distribution is symmetric based on this information alone.
D. The number of heights is very large - The information about the size of the population is not provided, so we cannot assume that the number of heights is very large.
E. The distribution of heights is unimodal - We do not have information about the number of modes (peaks) in the height distribution. The z-score doesn't give us any insight into whether the distribution is unimodal or multimodal.
Thus, the result of the following questions will be:
a) The child falls into the most extreme 5% group, we need to compare the z-score of 1.59 to the critical value for the 5th percentile.
b)The information to make assumptions about the skewness, symmetry, or the number of heights is not provided.

Answer:
Step-by-step explanation:
Given the order of operations A set of three scores to consists of the values 6, 3, and 2, we are to evaluate the following
1) Σ2X – 2
= 2(6)+2(3)+2(2) – 2
= 12+6+4–2
= 22–2
= 20
2) Σ(2X)² = (2×6)²+(2×3)²+(2×2)²
Σ(2X)² = 12²+6²+4²
Σ(2X)² = 144+36+16
Σ(2X)² = 144+52
Σ(2X)² = 196
The results of the order of operations are: [tex]\sum 2x -2 = 16[/tex] and [tex]\sum (2x)^2 =196[/tex]
The scores are given as:
x = 6, 3 and 2
(a) The first set of operationThis is represented as:
[tex]\sum 2x -2[/tex]
So, we have:
[tex]\sum 2x -2 = 2 \times 6 - 2 + 2 \times 3 - 2 + 2 \times 2 - 2[/tex]
Evaluate the products
[tex]\sum 2x -2 = 12 - 2 + 6 - 2 + 4- 2[/tex]
[tex]\sum 2x -2 = 16[/tex]
(a) The second set of operationThis is represented as:
[tex]\sum (2x)^2[/tex]
So, we have:
[tex]\sum (2x)^2 =(2 \times 6)^2 + (2 \times 3)^2 + (2 \times 2)^2[/tex]
Evaluate the products
[tex]\sum (2x)^2 =12^2 + 6^2 + 4^2[/tex]
Evaluate the squares
[tex]\sum (2x)^2 =144 + 36 + 16[/tex]
[tex]\sum (2x)^2 =196[/tex]
Hence, the results of the order of operations are:
[tex]\sum 2x -2 = 16[/tex] and [tex]\sum (2x)^2 =196[/tex]

Why does the problem of finding the zeros (i.e. the inputs where a function assumes the value zero) receive such disproportionate attention in algebra?A. Because the problem of finding where a function f assumes the value c, i.e. solving f(x) = c, is equivalent to finding where the function f(x)-c assumes the value zero; and c = O is the only number for which f(x) = c can be solved by factoring f(x). B. It's because usually you want to know where a function crosses the x-axis. Crossing a different axis parallel to that is just not that interesting. C. It's because knowing the zeros allows you to determine the end behavior of the function, and the vertical and horizontal asymptotes. D. Because O is the lowest value (i.e. the minimum) that a function can assume. In many math applications, we need to know the minimum value of a quantity.
Answer:
The answer is C
Step-by-step explanation:
Why does the problem of finding the "zeros" (the inputs where a function assumes the value of zero OR the value inputs for which the function is equal to zero) of a function receive such disproportionate attention in ALGEBRA?
(D) is wrong because zero is not the minimum value that a function can assume. A function could assume or be equal to a negative number or term and negative figures are less than zero.
The answer is (C) because knowing the zeros of a function allows you to determine the end behaviour of the function and the vertical & horizontal asymptotes on a graph/cartesian plane.

three angles are adjacent to each other and form 140.the largest angle is twice the smaller angle and the angle which is middle size is 24 more than the smallest. find the angles
Answer:
Smallest: 29, Middle: 53, Largest: 58
Step-by-step explanation:
We can represent the angles in this problem using an equation.
We'll use x to represent the smallest angle, and work out other ways to represent the others.
As the largest angle is twice that of the smaller angle, we can represent the largest angle as 2x as 2x is two times x.
The middle angle is 24 more than the smallest, so we can represent that one as x + 24, since it is 24 more than the smallest.
Now we have our angles all represented with x:
Smallest angle = x
Middle = x+24
Largest = 2x
We know that they all add together to 140 so our equation is:
x+2x+(x+24) = 140
Now we can solve for x!
We can remove the brackets (addition does not change the terms) and combine the terms:
x+2x+x+24=140
4x+24=140
Next we move the 24 to the other side so we can solve for x:
4x + 24 - 24 = 140 - 24
4x = 116
Finally we divide both sides by 4:
x=29
The smallest angle is 29!
Now we can use our representations to find the other angles:
Middle angle = x+24, therefore it is 29+24 = 53
Largest angle = 2x therefore it is 2*29 = 58
58+53+29=140 so we have successfully worked out our angles!
Hope this helped!

The Sports Brand Company is making a new shoe that has a wholesale price of $40, and it wishes to advertise a retail price of $89.99. What is the markup percentage? Give answer to nearest whole percent. (hint: change decimal to percent, % will not be typed)
Answer:
Markup Percentage = 125%
Step-by-step explanation:
The wholesale price is $40, the "selling price" is $89.99.
90-40=50 (Profit)
Now that we know the profit , we need to find the percentage.
To find this percentage we can use the formula: (M=Markup percent)
[tex]M=profit/cost*100%[/tex]
In this situation, we can insert PROFIT= 50, Cost=40
M=50/40*100
= 1.25*100
=125%

Step-by-step explanation:
The ratio is 9 : 7
The first number is 324
Let's build the proportion for it.
9 : 7 = 324 : x [We've to find x]
Product of Extremes = Product of Means=> 9 * x = 324 * 7
=> 9x = 2268
Dividing both sides by 9
=> x = 252
So, The other number is 252.

In this case, 100 is the only square number so only the square root of 100 will result in a rational number (10) or (10/1). The others are not square numbers so square rooting them will result in a long line of decimal points which cannot be expressed by a fraction.
