Choose all the expressions that are equal to 34. A. 815−511 B. 712+16 C. 56−112 D. 1+14 E. 1720−35
Answer:
A
Step-by-step explanation:
Given that you should Choose all the expressions that are equal to 304.
A. 815−511 = 304
B. 712+16 = 728
C. 56−112 = - 56
D. 1+14 = 15
E. 1720−35 = 1685
Among all these options, it's only option A that is 304.
Therefore, option A is the answer because it gives 304.

Find the area of the shape. Either enter an exact answer in terms of π or use 3.14 for π and enter your answer as a decimal. (ANSWER ASAP PLEASEE)
Please hellllp fasttttttt
Answer:
Step-by-step explanation:
Because lines [tex]m[/tex] and [tex]n[/tex] are parallel, angles 1, 3, 4, 6 are equivalent, and all remaining angles are also equivalent.
Knowing this, you can set up the following equation:
[tex]86 = 2x + 25[/tex]
[tex]86 - 25 = 2x[/tex]
[tex]61 = 2x[/tex]
[tex]x = 30.5[/tex]
Answer:
x = 30.5

Solve and graph y−5<7
Answer:
y < 12
Step-by-step explanation:
Add 5 on both sides since the opposite of subtraction is addition. Then cross it out where you will be left with y and 7 + 5 equals 12 so the answer is: y < 12
Solve for y. Go to attached image
Answer:
y=4Step-by-step explanation:
12(2y+1)-18y=36 <---- Distribute 12 into 2y+1
24y+12-18y=36 <----- Subtract 24y by 18y
6y+12=36 <---- Subtract 12 from 36
6y=24 <---- Divide 6 by 24
y=4

Answer:
The greatest common factor is 7
[tex]35 + 14 = 49[/tex]
Step-by-step explanation:
Given
[tex]35 + 14 =[/tex]
Required
Apply distributive property
Express 35 as 7 * 5 and 14 as 7 * 2
[tex]35 + 14 = 7 * 5 + 7 * 2[/tex]

Answer:
Please answer my question
Answer:
a = 15, b = - 14
Step-by-step explanation:
Given the 2 equations
[tex]\frac{a}{5}[/tex] - [tex]\frac{b}{2}[/tex] = 10 ( multiply through by 10 to clear the fractions )
2a - 5b = 100 → (1)
a - b = 29 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the a- term
- 2a + 2b = - 58 → (3)
Add (1) and (3) term by term to eliminate a
0 - 3b = 42
- 3b = 42 ( divide both sides by - 3 )
b = - 14
Substitute b = - 14 into (2) and evaluate for a
a - (- 14) = 29
a + 14 = 29 ( subtract 14 from both sides )
a = 15
Drow two different rectilinear shapes each with an area of 6 squares.
Answer:
We can draw a rectangle and a square.
First the square:
The area of a square of sidelength L is:
A = L^2
So if the area of this square must be 6 square units, we get:
6 square units = L^2
L = √(6 square units) = 2.45 units
Now for a rectangle, we know that for a rectangle of length L and width W, the area is:
A = L*W
Now let's give the width a value of 1 unit, then W = 1unit
A = L*1 unit
And we know that the area must be of 6 square units, then:
6 square units = L*1 unit
(6 square units)/(1 unit) = L
(6 units) = L

D −5.1+14.8d
Answer:
9.7d+4.1+5.1d-9.2
9.7d +5.1d+4.1-9.2 (take same element near)
d(9.7d +5.1) + 4.1-9.2

b. tan x
c. sin x
d. cos x
(cos2x+cos4x)/(sin2x-sin4x)=
a. cot x
b. -cot x
c. sin x
d. -tan x
Answer:
[tex](b)\\\tan x, \cot x[/tex]
Step-by-step explanation:
Given
trigonometric function is
[tex]\dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}[/tex]
Applying trigonometric formulae
[tex]\Rightarrow \cos C-\cos D=-\sin (\dfrac{C+D}{2})\sin (\dfrac{C-D}{2})\\\\\Rightarrow \sin C+\sin D=\sin (\dfrac{C+D}{2})\cos (\dfrac{C-D}{2})[/tex]
[tex]\Rightarrow \dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}=\dfrac{2\sin 3x\cdot \sin x}{2\sin 3x\cdot \cos x}\\\\\Rightarrow \dfrac{\sin x}{\cos x}=\tan x[/tex]
option (b) is correct
[tex]\Rightarrow \dfrac{\cos 2x+\cos 4x}{\sin 2x-\sin 4x}=\dfrac{2\cos 3x\cdot \cos x}{2\cos 3x\cdot \sin (-x)}=-\cot x[/tex]

Six jurors are to be selected from a pool of potential candidates to hear a civil case involving a lawsuit between two families. Unknown to the judge or any of the attorneys, of the prospective jurors are potentially prejudiced by being acquainted with one or more of the litigants. They will not disclose this during the jury selection process. If jurors are selected at random from this group of , find the probability that the number of potentially prejudiced jurors among the selected jurors is exactly .
Complete question :
Six jurors are to be selected from a pool of 20 potential candidates to hear a civil case involving a lawsuit between two families. Unknown to the judge or any of the attorneys, 2 of the 20 prospective jurors are potentially prejudiced by being acquainted with one or more of the litigants. They will not disclose this during the jury selection process. If 6 jurors are selected at random from this group of 20, find the probability that the number of potentially prejudiced jurors among the 6 selected jurors is ;
a. exactly 1
b. none
c. at most 2
Answer:
0.442 ; 0.479 ; 1
Step-by-step explanation:
Given:.
Total number of candidates = 20
Number of jurors to be selected = 6
Number of prejudiced jurors = 2
Required outcome / Total possible outcomes :
Using the combination formula :
nCr = n! ÷ (n-r)!r!
1.)
P(number of prejudiced jurors is exactly 1) :
[2C1 * 18C5] ÷ 20C6
(2*8568)÷ 38760
= 0.442
B.)
P(None of the jurors is prejudiced) :
[2C0 * 18C6] ÷ 20C6
(1 * 18564) ÷ 38760
= 0.479
C.)
P(at most 2 of the jurors are prejudiced)
P(x =0) + p(x = 1) + p(x = 2)
P(x = 2) :
[2C2 * 18C4] ÷ 20C6
(1 * 3060) ÷ 38760
= 0.079
P(x =0) + p(x = 1) + p(x = 2)
(0.479 + 0.442 + 0.079)
= 1
find the side length
Answer:
area of square=side²
36/49yd²=side²
(36/49yd²)²=side
6/7 yd=side
Answer:
s = [tex]\frac{6}{7}[/tex] yd
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the length of side )
Given A = [tex]\frac{36}{49}[/tex] , then
s² = [tex]\frac{36}{49}[/tex] ( take the square root of both sides )
s = [tex]\sqrt{\frac{36}{49} }[/tex] = [tex]\frac{\sqrt{36} }{\sqrt{49} }[/tex] = [tex]\frac{6}{7}[/tex]

Several million lottery tickets are sold, and 21% of the tickets are held by men. Suppose you select a random sample of people and let X represent the number of people in your sample for which are men with winning tickets. What type of random variable is X?
hypergeometric
Bernoulli
poisson
uniform
Answer:
hypergeometric
Step-by-step explanation:
For each winning ticket, there are only two possible outcomes. Either it is held by a men, or it is not.
There is a set number of X, and as the number of winning tickets decrease, the probability of a winning ticket being held by a men can decrease or increase. This is a characteristic of the hypergeometric distribution.

WILL GIVE BRAINLIEST!!!!!!! find the value of x. find the value of y.
Answer: x=20 y=20√2
Since this is a 45-90-45 right triangle, so sides are going to be the same. To solve for y, you have to use Pythagorean theorem. (a^2+b^2=c^2) So put in the a and b values, in this case, it's 20 and 20. (20^2+20^2=c^2) Then you can solve the exponents, (400+400=c^2) add them up (800=c^2), then square root everything which gives you y=20√2 or 28.28(rounded)
