This question is actually fairly simple...I'll work it out for you.
P + MN
P= 4
M = 5
N = 3
Now you substitute or 'plug-in' the numbers.
4 + 5 x 3
The rule of P.E.M.D.A.S states multiplication comes before addition, so 5 x 3 = 15.
Add 4 to 15, you get 19.
<u>Answer</u> : 19.

Answer:
~15.55 is the mean.
Step-by-step explanation:
The class of frequency is given as 0-9, 10-19 and 20-29.
First of all, let us taken middle value of class:



Formula for mean:

where f is the frequency
and m is the mean value calculated in above step (4.5, 14.5 and 24.5)
The frequencies are given as:
4.5 - 24
14.5 - 20
24.5 - 32
Putting the values in above formula:

Please refer to the attached image that contains the table for calculation of mean.
So, mean = ~15.55
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°
Here is the work with the answer. Hope this helps. God bless
