Answer:
8624
Step-by-step explanation:
let's write four blanks to represent the number _ _ _ _
by rule #10 we can fill in one digit
_ 6 _ _
using rule 4 we can wee that the ones digit is 4
_ 6 _ 4
We know that the thousand's digit has to be an even number greater than 7 (which leaves 8 only)
8 6 _ 4
using rule 5 we can see that the tens digit is 2

If a fair coin is tossed 8 times, what is the probability, to the nearest thousandth, of getting exactly 2 tails?
Answer:
0.109
Step-by-step explanation:
Probability is expressed by the number of desirable outcomes over the total outcomes. The total outcomes would be 2^8 because there are two possibilities in each flip, and using the fundamental counting principle, you get 2^8 total outcomes. Next, to find the amount of situations where you only flip two tails, you use 8 choose 2 because we are looking for the amount of ways you can choose 2 out of the 8 to be tails. 8 choose 2 is the same as:
8! / (6! x 2!) - 28
So, the probability is:
28 / 2^8 or 28/256
As a decimal, this is: 0.109375
And rounded to the nearest thousandth it's 0.109
Amplitude and Period
What is the period of the sine function y = sin (4x) ?
a. /pi
b. 2
c. /pi/2
d. /pi/4
Please select the best answer from the choices provided
Answer:
c. /pi/2
Step-by-step explanation:
[tex]y = \sin(4x) \\ y = 2\pi \omega[/tex]
Option C , pi/2 is the period of the sine function y = sin (4x)
What is Amplitude ?The amplitude of a periodic variable is a measure of its change in a single period.
The amplitude of a non-periodic signal is its magnitude compared with a reference value.
sin4x=sin(4x+4h)
sin(θ+2π)=sinθ , we have 4h=2π , h=π/2
or it can be also understood as
The amplitude and period of y = a sin (bx + c ) are a and 2π/b
Here, a = 1 and b = 4.
This sine wave oscillates between the crests at y = 1 and the lowest points at y= -1 periodically, with period π/2 for one full wave.
period of sin(4x) is (1/4)x(period of sin(x))
= (1/4)x(2pi)
= (pi/2) .

Find the area of the circle. Round your answer the nearest whole number, if necessary.
area: about
in.2
Answer:
Area = 314 in.²
Step-by-step explanation:
Radius of the circle = 10 in.
Formula for area of a circle = πr²
Radius (r) = 10 in.
Plug in the value of r into the formula
Area = π*10²
Area = π*100
Area = 314.159
Area = 314 in.² (nearest whole number)
Answer:
The area of circle is 314 in².
Step-by-step explanation:
Given :
Radius of circle = 10 in.To Find :
Area of circleUsing Formula :
[tex]\star{\small{\underline{\boxed{\sf{\red{Area_{(Circle)} = \pi{r}^{2}}}}}}}[/tex]
π = 3.14 r = radiusSolution :
Finding the area of circle by substituting the values in the formula :
[tex] \begin{gathered} \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = \pi{r}^{2}}}} \\ \\ \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = 3.14 \times {(10)}^{2}}}} \\ \\ \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = 3.14 \times {(10 \times 10)}}}} \\ \\ \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = 3.14 \times {(100)}}}} \\ \\ \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = 3.14 \times 100}}} \\ \\ \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = \dfrac{314}{100} \times 100}}} \\ \\\qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = \dfrac{314}{\cancel{100}} \times \cancel{100}}}} \\ \\ \qquad\dashrightarrow{\small{\sf{Area_{(Circle)} = 314 \: {in}^{2}}}} \\ \\ \qquad\star{\small{\underline{\boxed{\sf{\pink{Area_{(Circle)} = 314 \: {in}^{2}}}}}}}\end{gathered}[/tex]
Hence, the area of circle is 314 cm².

Step-by-step explanation:
Given
[tex]y = 3x - 5[/tex]
Solving (a): Make a table
Considering the values of x from 0 to 5, we have:
When [tex]x = 0[/tex]
[tex]y = 3x - 5 \to 3 * 0 - 5 = -5[/tex]
When [tex]x = 1[/tex]
[tex]y = 3x - 5 \to 3 * 1 - 5 = -2[/tex]
When [tex]x = 2[/tex]
[tex]y = 3x - 5 \to 3 * 2 - 5 = 1[/tex]
When [tex]x = 3[/tex]
[tex]y = 3x - 5 \to 3 * 9 - 5 = 4[/tex]
When [tex]x = 4[/tex]
[tex]y = 3x - 5 \to 3 * 4 - 5 = 7[/tex]
When [tex]x = 5[/tex]
[tex]y = 3x - 5 \to 3 * 5 - 5 = 10[/tex]
So, we have:

Answer:
x=13
y=32
Step-by-step explanation:
x+y=45
x+19=y
45-y+19=y
2y=64
y=32
x=13
Answer: The other number is 19 more than that number represented by x + 19
Equation: x + (x + 19) = 45
The numbers are 13 and 32
Step-by-step explanation:
So we know that the sum is 45, and that one of the numbers in the equation is 19 more than the other. We can call one of the numbers "x". The instructions tell us that the second number is 19 more than x, so the second number can be written as this equation: x+19
Equation: x + (x + 19) = 45
2x + 19 = 45
2x = 26
x = 13
Plug x back into the equation to find the second number (x + 19)
x + 19
13 + 19 = 32

Find point Z that partitions the directed line segment XY in the ratio of 3:2 where X(-4, -2) and Y(6, 3).
Answer:
(2 , 1)
Step-by-step explanation:
point Z (x, y)
x = 3/5 × (6+4) + (-4)
= 3/5×10 -4
= 6-4
= 2
y = 3/5 ×(3+2) + (-2)
= 3/5 ×5 -2
= 3-2
= 1
so, point Z => (2 , 1)

Two sides of a parallelogram are 9.5 feet and 4.9 feet. The measure of the angle between these sides is 96°. Find the area of the parallelogram to the nearest 10th of a square foot
Answer:
The area of the parallelogram is of 46.3 square feet.
Step-by-step explanation:
Area of a parallelogram:
The area of a parallelogram, given two sides a and b and the angle C between them, is given by:
[tex]A = ab\sin{C}[/tex]
In this question:
[tex]a = 9.5, b = 4.9, C = 96º[/tex]
Sides in feet, so area in square feet.
Area
[tex]A = ab\sin{C} = 9.5*4.9\sin{96º} = 46.3[/tex]
The area of the parallelogram is of 46.3 square feet.

Question for 1 B)
Answer:
x = 117
Step-by-step explanation:
Given
11 - [tex]\sqrt{x+4}[/tex] = 0 ( subtract 11 from both sides )
- [tex]\sqrt{x+4}[/tex] = - 11 ( square both sides )
(- [tex]\sqrt{x+4}[/tex] )² = (- 11)²
x + 4 = 121 ( subtract 4 from both sides )
x = 117
Three postal workers can sort a stack of mail 10 minutes , 35 minutes, and 70 minutes respectively. find how long it takes them to sort the mail if all three work together
9514 1404 393
Answer:
7 minutes
Step-by-step explanation:
The total of stacks per minute is ...
1/10 +1/35 +1/70 = (7+2+1)/70 = 1/7 . . . . stacks per minute
The rate in minutes per stack is the reciprocal of this.
Working together, the workers can sort a stack of mail in 7 minutes.

help with the Triangle sum theorem
Answer:
180
Step-by-step explanation:
If you add 60 +60 + 60, or 60 + 50 + 70, both would add up to 180, since x = 60. This is why both triangles, have a complete of 180.
Answer:
A triangle has 3 sides in every triangle all the three sides should sum up to 180°.
In the 1st figure,
70+50+x=180 (being sum of triangle)
now 120+x=180
x=180-120
=60
Step-by-step explanation:
In the 2nd figure
x is 60
60+60+60=180,
