Answer:
Standardized score is -0.22
Step-by-step explanation:
Here, we want to calculate z-score
z-score = (x - mean)/SD
z-score = (163.2-166.3)/14 = -0.22
Solve for x.
-3/5x = 15
A. -25
B. -9
C. -6
D. 9
Answer: If the question is formed as (- 3/5) x = 15
then A is correct
X=-25

The ratio of girls to boys in a a chess club was 4 : 4. There were 24 boys. How many total members were there in the club?
Answer:
48 members
Step-by-step explanation:
Add the numbers in the ratio: 4+4=8
Divide: 24boys/4=6
Multiply: 6*8=48
Now we know there are 48 people. Take it a step forward..how many girls?
EASY!
4*6=24 girls
We know this works because 24+24=48
*Note: the 4's come from the ratio*
Three baseball players are playing catch. Herman is 6 meters south of Luca and 8 meters west of valentina. How far does Luca need to throw the ball to get it to Valentina
Answer:
Luca needs to throw the ball 10 meters to get to Valentina.
Step-by-step explanation:
Distance Between two Points in the Plane
Let's assume Luca is at the origin of coordinates (0,0).
Since Herman is 6 meters south of Luca, he is located at (0,-8).
We also know Herman is 8 meters west of Valentina, or equivalently, Valentina is 8 meters east of Herman. This locates Valentina at (6,-8).
If Luca wanted to throw the ball to Valentina, he would need to cover the distance between them.
Thus the problem reduces to find the distance between (0,0) and (6,-8).
Given two points A(x,y) and B(w,z), the distance between them is:
[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]
Applying the formula:
[tex]d=\sqrt{(-8-0)^2+(6-0)^2}[/tex]
[tex]d=\sqrt{(-8)^2+(6)^2}[/tex]
[tex]d=\sqrt{64+36}=\sqrt{100}=10[/tex]
d=10 m
Luca needs to throw the ball 10 meters to get to Valentina.

The theorem that justifies why the two larger triangles are congruent to each other is: Hypotenuse-leg Congruence Theorem (HL).
What is the Hypotenuse-Leg Congruence Theorem?The Hypotenuse-leg Congruence Theorem (HL) states that if one leg and hypotenuse of a right triangle are congruent to one corresponding leg and hypotenuse of another, both right triangles are congruent.
The two right triangles have a pair of congruent legs and a pair of congruent hypotenuse.
Therefore, the theorem that justifies why the two larger triangles are congruent to each other is: Hypotenuse-leg Congruence Theorem (HL).

Ellen wants to purchase a book that is regularly priced at $18. The book is discounted 15%. She also needs to pay a 6% sales tax on the discounted price.
What is the total amount Ellen will pay for the book?
Answer:
Ellen will pay $16.22 for the book.
Step-by-step explanation:
Part 1:
We know that the book Ellen wants to buy has a normal price of $18. However, there is a 15% discount. So, let's calculate 15% of $18.
18 x 0.15 = $2.70
This lets us know that there is a $2.70 discount.
Now, let's subtract the discount from the regular price.
18 - 2.70 = $15.30
So, now we know the discounted price is $15.30
Part 2:
We also know that Ellen has to pay 6% sales tax. The discounted price is 100% of the price, plus 6% is 106%. Let's calculate the tax to figure out the total amount.
15.30 x 1.06 = $16.22 when rounded to the nearest cent.
Therefore, Ellen will pay the total amount of $16.22.
Answer:
$16.22
Step-by-step explanation:
marked price = $18 = 100%
discount = $? = 15%
selling price/ = $? = 85%
discounted price- this price is lower than the marked price as they have given you a DISCOUNT- an amount of money DEDUCTED.(a.k.a selling price)
selling price = 85% x $18 = $15.3= discounted price
100%
sales tax=6%
= 6 x 15.3 = 0.918 = $0.92=sales tax
100
total amount = discounted price + sales tax
= 15.3 + 0.92
= $16.22

A hurricane was detected in the Atlantic around 5 a.m. The National Weather Service determined that it will make landfall at a location described by a vector with components [3, 7]. Around 6 a.m. on the same path, the hurricane is 1/10 the total distance from where it was detected initially to where it will make landfall.
If the hurricane is traveling on a straight path, what are the characteristics of the vector representing the path of the hurricane at 6 a.m.?
A) components: [0.30, 0.70], magnitude: 0.76
B) components: [0.30, 0.70], magnitude: 76
C) components: [30,70], magnitude: 0.76
D) components: [30,70], magnitude: 76
Answer:
The correct option is;
A) Components: [0.30, 0.70], magnitude: 0.76
Step-by-step explanation:
The given parameters are;
The path of the of the airplane at 5 a.m. given by The National Weather Service = [3, 7]
The location of the hurricane at 6 a.m. = 1/10 of the total distance between the point where it was detected to the point where it is predicted to make land fall
Therefore;
The components of the vector at 6.00 a.m. = 1/10 × [3, 7] = [0.3, 0.7]
The magnitude of the vector at 6.00 a. m. = √(0.3² + 0.7²) ≈ 0.76.
Jay O'Brian bought two magazines. One cost $3.50 more than the other. The total cost was $17.00.
Which amount did Jay pay for the lower priced magazine?
A.20.50
B.13.50
C.10.25
D.8.25
E. 6.75
Answer:
E. $6.75
Step-by-step explanation:
Answer:
E
Step-by-step explanation:
We would have to subtract the total cost to the cost that is $3.50 more than the other
We do $17.00 - $3.50, would give us $13.50,
We divide the answer by two as O'Brian bought two magazine,
this will leave us with the answer 13.50/2 = 6.75

Leading term of -20(x - 2)^15 (4-x)^11
9514 1404 393
Answer:
20x^26
Step-by-step explanation:
The leading term is the one with the highest degree.
In the expansion of (x-2)^15, that will be x^15.
In the expansion of (4-x)^11, that will be (-x)^11 = -x^11.
So, the leading term of the product is ...
(-20)(x^15)(-x^11) = 20x^26
__
In the attached, terms are listed in order of increasing degree, so the "leading" term appears last.
============================================
Work Shown:
The leading term for (x-2)^15 is x^15
The leading term for (4-x)^11 is -x^11
Multiply the outer value -20 with each of those leading terms to get
-20*x^15*(-x^11)
20x^(15+11)
20x^26
which is the leading term of -20(x - 2)^15 (4-x)^11

Which statements describe the domain and range of g(x)? Select two options. The function g(x) is defined for all real numbers x. The maximum value of the range is 4. The maximum value of the domain is 3. The range of g(x) is {y| –1 < y ≤ 4}. The domain of g(x) is {x| –4 < x ≤ 3}.
Answer:
The correct two options are:
The maximum value of the range is 4.
The range of g(x) is {y| –1 < y ≤ 4}.
Step-by-step explanation:
The missing diagram is attached in the image below:
It is pertinent to understand that the domain is the set of all possible mathematical points where a given function is defined. In the diagram attached below, the domain relates to all possible values of x.
The range relates to all possible values of y.
From the graphical diagram;
The domain is (-4 ≤ x ≤ -1 and 0 ≤ x < 3); &
The range is -1 < y ≤ 4.
We could see from the graph as well that, the maximum value of the range extends from -1 to 4 which indicates that the largest possible value is 4.

Answer:
$14Step-by-step explanation:
Step one:
given data
we are told that the discounted price is $7
and the applied discount is 50%
so if 50% of the original price is $7
Step two:
let the original price be x
50/100*x=7
0.5x=7
divide both sides by 0.5
x=7/0.5
x=$14
These means that the original price is $14

A person receives a paycheck of d dollars. The person spends 18% of the
paycheck on rent, 15% of the paycheck on insurance, and 22% of the paycheck
on food and puts the remainder of the paycheck into savings.
If the amount the person puts into savings can be
represented by the
expression d - 0.18d - 0.15d - 0.22d, which expression also represents the
amount the person puts into savings?
O 0.45d
O 0.550
O 1.450
O 1.550
Answer:
0.45d
Step-by-step explanation:
Given that :
Amount of paycheck = d
Amount spent on rent = 18%
Amount spent on insurance = 15%
Amount spent on food = 22%
Amount put into savings = d - 0.18d - 0.15d - 0.22d
Amount put into savings = d - ( 0.18d + 0.15d + 0.22d)
d - 0.55d
Amount put into savings = 0.45d
