Answer:
4.4 inches
Step-by-step explanation:
Here, we are interested in calculating the value of x.
Mathematically, a line that comes from the center of the circle and extends to a chord, divides the chord into two equal parts.
This means what we have is a right angled triangle with the radius being the hypotenuse, the half of the length of the chord as the other side of the triangle.
3.7 is half the length of the chord i.e 7.4/2
Thus;
using Pythagoras’ theorem
x^2 = 2.4^2 + 3.7^2
Pythagoras’ posited that the square of the hypotenuse is equal to the sum of the squares of the other two sides of the triangle.
Thus;
x^2 =5.76 + 13.69
x^2 = 19.45
x = √(19.45)
x = 4.41 inches which is 4.4 inches to the nearest tenth
Answer:
Central angle = 31 / 4 radians
=
Length of the arc = (3 1 / 4) (radius) = 45 in
=
=> radius = 45 in * 4 / (31) = 45 * 4 / (3 * 3.14) in
=
radius = 19.1 in
=
Answer: 19.1 in

Consider a game in which you draw playing cards from a standard 52-card deck, one at a time. If a player draws a face card (a jack, a queen, or a king), the player is awarded 10 points. Any other card drawn costs the player 3 points. What is the expected value of drawing a card in this game? A. 0 points B. 3 points C. 6.5 points D. 10 points
Answer: B
Step-by-step explanation: There are many less face cards in the deck than other cards, you would think youre getting 3 points each time rather than thinking 10 points each time

First, we think of two numbers such that
If we multiply them, we'll get 6
If we add them, we'll get -5
These numbers are -2 and -3.
Write them here:
(x-2)(x-3)
Now, how do we get (x-2)(x-3) from x(x-2)-3(x-2)?
Notice that (x-2) is the common term, so we factor it out:
(x-2)
And now, we write the other two terms that are left in the parentheses:
(And the terms left are x and -3)
(x-2)(x-3)
Notice that we ended up with the same answer.

A large tank is 120 meters long, 65 meters wide, and 48
meters high. Express the volume of the tank in cubic
meters using scientific notation.
Step-by-step explanation:
the volume of a rectangular block or tank is
length × width × height
so, it is like all regular 3D objects
base area × height.
so, we get
120 × 75 × 48 = 374,400 m³ = 3.744 × 10⁵ m³
why ?
374,400 = 374400 × 10⁰ = 37440 × 10¹ =
= 3744 × 10² = 374.4 × 10³ = 37.44 × 10⁴ =
= 3.744 × 10⁵

Patton is organizing his stamp collection into a book. He has 42 foreign stamps and 70 U.S. stamps. He wants every page to have the same number of foreign stamps and the same number of U.S. stamps. He also wants to put the greatest possible number of stamps on each page. How many pages will he use?
A) 2
B) 6
C) 10
D) 7
Answer:
D. 7
Step-by-step explanation:
42 + 70 = 112 stamps altogether.
112 can be divided by 2, 4, 7, 8, 14, 16, 28, 56
to be more simpler, since there are options, we can cross out the other numbers not shown in the options. then see that 6 and 10 are not divisible by 112, so cross them out. it will left with option A and option D.
option A is 2. if he uses two pages, then each page should have a total of 56 stamps. however, foreign stamps have an amount of 42 only, so it is quite impossible to fit in more than 42.
option D is 7. if he uses 7 pages, then each page could fit in 16 stamps.
so the answer will be option D.

Degree Male Female
Associate 245 433
Bachelors 598 858
Advanced 293 376
P(the recipient is male)= 40.5%
p(the degree is a bachelors) = 52%
p(the recipient is female, given that the degree is advanced) = 56.2%
p( the degree is not an associates, given that the recipient is male) = 78.4%
What are the probabilities?Probability determines the chances that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
P(the recipient is male) = total number of males / total number of recipients
1136/2803 = 40.5%
p(the degree is a bachelors) = total number of bachelors degree / total number of degree
= 1456 / 2803 = 52%
p(the recipient is female, given that the degree is advanced) = total number of females with advanced degree / total number of advanced dgree
376 / 669 = 56.2%
p( the degree is not an associates, given that the recipient is male) = number of males that that have degrees other than associates / total number of males
