Answer:
Step-by-step explanation:
P(g=1) is equal to
1-P(g=0)-P(g=2)
P(g=0)=(7/12)(6/11)
P(g=2)=(5/12)(4/11) so
P(g=1)=1-(42/132)-(20/132)
P(g=1)=(132-42-20)/132
P(g=1)=70/132
P(g=1)=35/66

Answer:
1. 1=18°, 2=90°
2. 1=85°
3. 1=97°
4. 2=83°
5. 3=49°
6. 1=94°
7. 4=45°
8. 3=65°
9. 2=79°
10. 5=73°
11. 6=147°
12. 1=26°
13. 2=32°
Step-by-step explanation:
1. all angles of a triangle equal 180. 2 is 90 degrees because you can look across to find the symbol. Then you subtract 180 by 72 and 90 to get 18.
2. do the same thing as last time, 180 minus 40 and 55.
3. In order to figure this out, you need to have the angle 2. One you have 83, angles like this, together will add up to 360 if you put 2 of them together. 83×2=166. 360-166=194. 194/2=97.
4. To figure this out, you find the angle across from it because those are always the same. Follow the same process to subtract 39 and 58 from 180 to get 83.
5.Now that you have the angle 2 you can figure this one out as well, again, follow the process of subtracting the two opposite angles from 180 to get 49.

Moe painted the lid of a barrel. The circumference of the lid is 32 inches. Which
measurement is closest to the area of the lid in square inches?
Answer:
A ≈ 81.487 in²
Step-by-step explanation:
We know that circumference is C = 2πr, where r is the radius.
So,
C = 2πr
32 = 2(3.14)r
[tex]r=\frac{32}{2(3.14)}[/tex]
r ≈ 5.093 in
We also know that the formula for the area of a circle is A = πr², so:
A = πr²
A = (3.14)(5.093)²
A ≈ 81.487 in²
If 0 < b ≤ 90 and cos(11b + 2) = sin(12b − 4), what is the value of b? b = 3 b = 4 b = 5 b = 6
Answer:
[tex]b = 6[/tex]
Step-by-step explanation:
Given
[tex]0<b\le 90[/tex]
[tex]\cos(11b + 2) = \sin(12b - 4)[/tex]
Required
Find b
To solve this, we make use of the following trigonometry rule:
If [tex]\cos(\alpha) = \sin(\beta)[/tex]
Then: [tex]\alpha + \beta = 90[/tex]
So:
[tex]11b + 2 = 12b - 4[/tex]
Collect like terms
[tex]11b - 12b = - 4 - 2[/tex]
[tex]-b = - 6[/tex]
Multiply both sides by -1
[tex]b = 6[/tex]

Answer:

log x + log y ⇔ log (xy )
log x - log y ⇔ log ([tex]\frac{x}{y}[/tex] )
Given
log[tex]\frac{14}{3}[/tex] + log[tex]\frac{11}{5}[/tex] - log[tex]\frac{22}{15}[/tex]

Find the lateral surface area of the triangular prism.
A) 420 cm2
B) 480 cm2
C) 540 cm2
D) 620 cm2
Answer:
620
Step-by-step explanation:
other dood is wrong lol i did the math and took the test AND got it right
The lateral surface area of the triangular prism is 480 square cm,
option (B) is correct.
It is given that the triangular prism has a 10 cm height and its sides are 16 cm, 12 cm, and 20 cm respectively.
It is required to find the lateral surface area.
What is the lateral surface area?It is defined as the surface area of an object excluding its top and base areas, it is different from the total area.
We know that,
The lateral surface area of triangular prism = perimeter of the
base×height
= (a + b + c ) × h
We have, a = 16, b = 20 cm, c = 12 cm, and h =10 cm.
Putting these values in the above formula, we get:
[tex]\rm = (16+20+12) \times10\\\\\rm = 48\times 10\\\\\rm = 480 \ cm^2[/tex]
Thus, the lateral surface area of the triangular prism is 480 square cm,
option (B) is correct.

Answer:
56.7
Step-by-step explanation:
Hello There!
Trigonometric Ratios
sin = opposite divided by hypotenuse
cos = adjacent divided by hypotenuse
tan = opposite divided by adjacent
we need to find x and we are given its opposite side length and the hypotenuse
so the trigonometric ratio we need to use is sin
knowing that sin = opposite side divided by hypotenuse we create an equation
[tex]sin(x)=\frac{51}{61}\\\frac{51}{61} = .8360655738\\arcsin(sinX)=x\\arcsin(.8360655738)=56.72695659[/tex]
our final step is to round to the nearest tenth of a degree
so we can conclude that the measure of angle A is 56.7
note: arcsin = inverse of sin
Answer:
56.7
Step-by-step explanation:
so opposite the angle we are working out is "o"And the longest side is the hypotunese but just remember it as "h"a is the remaining side but does not have a value and is blank therefore we need to worry about this sideWe have "o" and "h" which is the formula triangle with sin o/sin*hBut as we are working out the angle(sin) we change the formula so it is sin=0/hsin=51/61sin=0.8then you click the shift or 2nd function button on your calculator and the sin button and this is your answer 56.7so the angle is 56.7area of this question?

Answer:
C) 76 cm²
Step-by-step explanation:
area = (8 x 8 ) + (3 x 8 x 0.5) = 76 cm²
another way is:
area = 1/2(b1 + b2)(h)
area = 1/2(11 + 8)(8) = 76 cm²
Answer:
76
Step-by-step explanation:
Hello There!
The area can be found by using this formula
[tex]A=\frac{a+b}{2} h[/tex]
where a and b = bases and h = height
we need to find the height before we can find the area
the shape was split into a triangle and a square
because its a square and one of the side lengths is equal to 8cm the height will be equal to 8cm
now we plug in the known information into the formula
[tex]A=\frac{11+8}{2} 8\\11+8=19\\\frac{19}{2} =8.5\\8.5*8=76\\A=76[/tex]
so we can conclude that the area of the trapezoid is 76 square centimeters
