Answer:
There are 123,410 ways
Step-by-step explanation:
The number of ways or combinations in which we can select k elements from a group of n elements is given by:
![\frac{n!}{k!(n-k)!}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%21%7D%7Bk%21%28n-k%29%21%7D)
In this case, we can replace n by 43 and k by 4, because we are going to select 4 light bulbs from a batch of 43 light bulbs.
So, the number of combinations is calculated as:
![\frac{43!}{4!(43-4)!}=123,140](https://tex.z-dn.net/?f=%5Cfrac%7B43%21%7D%7B4%21%2843-4%29%21%7D%3D123%2C140)
It means that there 123,410 ways to select 4 light bulbs from a batch of 43 lights bulbs to be tested for defects

it is B
Step-by-step explanation: 25 goes in 1 hundred 4 times And that gets us to 24
Answer:
m<ABC=94°
m<BCD=25°
m<ACB=43°
Step-by-step explanation:
To find <mBCD
m<ABD=133°, so m<CBD=133° too.
A triangle is equal to 180°.
22°+133°=155°
80°-155°=25°
To find <mACB
You first need to know triangle ACD measurements.
m<ADC=44° (22°+22°)
Then you take the two 25 and add them.
25°+25°=50°
50°+44°=94°
180°-94°=86°
86°÷2=43°
To find m<ABC
43°+43°=86°
180°-86°=94°
1,995,298 rounded to the nearest 10,000 is 2,000,000
