Answer:
1/16
Step-by-step explanation:
There is a 1/2 chance to flip a heads.
So, in this case, we would multiply 1/2 four times in reference to the coins being flipped a total of 4 times to find its probability.
1/2 x 1/2 x 1/2 x 1/2 = 1/16
Thus, there is a 1/16 chance that you'd get heads four times in a row.
given a set of numbers (0,1,2,3,4,5,6) if one of the set is chosen at random, find the
probability that the number is a solution of 3x-4 < 11
Answer:
This probability is 5/7
Step-by-step explanation:
Rewriting this problem may make it appear to be more manageable.
The probability that the number is a solution of 3x-4 < 1 simplies to "x < 5".
This probability is 5/7, since {0, 1, 2, 3, 4} are all less than 5.
Think of 5 positive integers that have a mode of 2, a median of 5, a mean of 6 and a range of 10.
Step-by-step explanation:
2 2 5 9 and 12
mode= 2
median = 5
Range : 12- 2 =10
Mean: 2+2+ 5+ 9+ 12=30
30÷ 5 = 6
1) If the perimeter of triangle STU is 125 cm, and segments TW, VW, and VT measure 21 cm, 30 cm, and 24 cm, respectively, what is the length of segment SU?
GIVEN: The perimeter of triangle STU is 125.
The segments TW=21 cm
VW=30 cm
VT=24 cm
TO FIND: The length of the segment SU.
SOLUTION:
As corresponding sides must be same. so we have,
[tex]\frac{TV}{TS}=\frac{TW}{TU}\\\\ \frac{24}{TS}=\frac{21}{TU}\\\frac{TU}{TS}=\frac{7}{8}=k(say)\\[/tex]
Then, TU=7k and TS=8k
[tex]\frac{TV}{TS}=\frac{VW}{SU}\\\\ \frac{24}{TS}=\frac{30}{SU}\\\frac{24}{8k}=\frac{30}{SU}\\SU=10k[/tex]
As the perimeter of triangle STU is 125.
so,
8·k+7·k+10·k=125
⇒25.k=125
⇒k=5
Therefore, SU=10×5=50

FG intersects HI at point E. What is the value of x, in degrees?
Answer:
6x-36=120
6x=120+36
6x=156
x=26
Answer:
X is equal to 26
Step-by-step explanation:
this is becasue 6x-36 is equal to 120 there for you can move the 36 over to make 156 so now you have 6x=156 now you just divide by 6 leaving you with x=26

Which of the following expressions will produce an answer with three significant figures? Check all that apply. A. 101 - 83.4 B. 121 - 1.75 O C. 7.23 + 12.6 D. 17. 1.5
Answer: option A and D results in 3 significant figures.
Step-by-step explanation:
A. [tex]101 - 83.4 =17.6[/tex]
The number 17.6 has three significant figures.
B. [tex]121 - 1.75 =119.25[/tex]
The number 119.25 has 5 significant figures
C. [tex]7.23 + 12.6=19.83[/tex]
The number of 19.83 has 4 significant figures.
D. [tex]17\cdot 1.5=25.5[/tex]
The number of 25.5 has 3 significant figures.
Hence, option A and D results in 3 significant figures.
The variables x, y, and z vary jointly.
1. If x = 4, y = 3, and z = 24, what is the constant of variation, k?
2. Now find z when x = -3 and y = 4.
k=
When x = -3 and y = 4, z =
Answer:
k = 18
when x = 4, y = 3, z = -24
Step-by-step explanation:
x = k * y * z
Find k when x = 4, y = 3, and z = 24
4 = k * 3 * 24
4 = k * 72
4 = 72k
k = 72/4
k = 18
find z when x = -3 and y = 4
x = k * y * z
-3 = 18 * 4 * z
-3 = 72 * z
-3 = 72z
z = 72/-3
z = -24

The diameter of Jacob's circular tabletop is 6 feet. What is the area, in square feet, of Jacob's tabletop? A 6 B. 9 С. 12 D 36
Answer:
B. 9
Step-by-step explanation:
the area = π × 3² = 9π ft²
Area of a circle = pi x R^2
R is the radius which is 1/2 the diameter.
R = 6/2 = 3 feet
Area = pi x3^2
Area = 9pi
The answer is B

round 4.776 to the nearest hundred
The round off of 4.776 to the nearest hundred results in 4.800.
To round 4.776 to the nearest hundred
Focus at the digit in the hundredth's place, which is the second decimal place.
In this case, the digit in the hundredth's place is 7.
Since 7 is greater than or equal to 5, we round up the previous digit, which is 7.
Therefore, rounding 4.776 to the nearest hundred results in 4.800.

PLs, help me with this question
Answer:
See below.
Step-by-step explanation:
Perimeter: use the Distance Formula [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Distance from (-3, 4) to (4, 5) is
[tex]\sqrt{(5-4)^2+(4-(-3))^2}=\sqrt{1+49}=\sqrt{50}=5\sqrt{2}[/tex]
Distance from (4, 5) to (2, -3) is
[tex]\sqrt{(2-4)^2+(-3-5)^2}=\sqrt{4+64}=\sqrt{68}=2\sqrt{17}[/tex]
Distance from (2, -3) to (-4, 4) is
[tex]\sqrt{(-4-2)^2+(-4-(-3))}=\sqrt{36+1}=\sqrt{37}[/tex]
Distance from (-4, 4) to (-3, 4) is
[tex]\sqrt{(-4-(-3))^2+(4-(-4))^2}=\sqrt{1+64}=\sqrt{65}[/tex]
The perimeter is the sum of all these distances.
Area:
To find the area of the figure, one method is to draw a rectangle around the entire figure, then add line segments that cut up the unwanted area into rectangles and triangles, add those areas together, then subtract the total from the area of the surrounding rectangle. See the attached figure.
The surrounding rectangle has area 8 x 9 = 72 square units.
The unwanted areas (green rectangles and four triangles). Remember, the area of a triangle is (1/2)(length)(width).
Rectangle A: 1 x 1 = 1 square unit
Triangle B: (1/2)(7)(1) = 3.5 square units
Triangle C: (1/2)(8)(1) = 4 square units
Triangle D: (1/2)(8)(2) = 8 square units
Triangle E: (1/2)(6)(1) = 3 square units
Rectangle F: 2 x 1 = 2 square units
Total of unwanted area: 1 + 3.5 + 4 + 8 + 3 + 2 = 21.5 square units
Subtract this total from the surrounding rectangle's area to get
72 - 21.5 = 50.5 square units

Find the values of x and y in the picture. Express answers in simplest radical form. (square root form)
Answers:
x = 8
y = 15*sqrt(2)
===========================================================
Explanation:
This is a 45-45-90 triangle. The right triangle is isosceles.
This means the two legs 3x-9 and x+7 are the same length
3x-9 = x+7
3x-x = 7+9
2x = 16
x = 16/2
x = 8
If x = 8, then each leg is...
3x-9 = 3(8)-9 = 24-9 = 15
x+7 = 8+7 = 15
Each leg is 15 units long to help confirm we have the correct x value.
---------------
The hypotenuse y is exactly sqrt(2) times that of the leg length.
Therefore, y = 15*sqrt(2) since earlier we found each leg is 15 units long.
15*sqrt(2) = 21.213 approximately
