Percentage Calculator: What is 20 percent of 16000.? = 3200.
Answer:
answer 3200 your welcome thats the answer
A school has 320 girls and 250 boys the probability of a girl being left handed is 0.2 the probability of a boy being left handed is 0.1 estimate the amount of left handed people there are in the school
320 girls & 250 boys
0.2 probability 0.1 probability
320 x 0.2 = 64
250 x 0.1 = 25
64 + 25 = 89
There are approximately 89 students in the school that are left-handed.
Answer
89% of the people are left handed
Step-by-Step Explanation
To find this you have to first do 320 x 0.2
320 x 0.2= 64
To find it for boys you have to do 250 x 0.1.
250 x 0.1= 25
SO, the answer is 89%. 64% of girls and 25% of boys

Answer:
y + 1 = 4/3(x - 9)
Step-by-step explanation:
Point-slope form: y - y₁ = m(x - x₁)
Substitute the numbers into the equation:
y - (-1) = 4/3(x - 9)
y + 1 = 4/3(x - 9)

Answer:
UW = EW+UE=2×EW because, EW=UE
7x-2=2×6= 12
7x=14
x=14/7
x=2
2 is the right answer.x + 80 = 180 - (64 + 36)
x + 80 = 180 - 100
x + 80 = 80
x = 0
0 is the right answer.does anyone know how to solve this using the sine rule?
Answer:
Step-by-step explanation:
According to sine law of trigonometric functions,
sin(α)/a =sin(β)/b
hence using this
sin(18)/y = sin(x)/2y
sin(x)=2*sin(18)
sin(x)=2*0.309
sin(x)= 0.618
x=sin-1(0.618) ( sin-1 is sine inverse)
x=38.17 °
please help, i’m not smart enough for this.
the missing length needs to be found.
it’s pythagorean theorem
Answer:
[tex]\sqrt{260}[/tex]
Step-by-step explanation:
a^2 +b^2 = c^2. Since 18 would be c in this equation, you just do 18 squared minus 8 squared.
Answer:
17.89 m
Step-by-step explanation:
A^2+B^2=C^2
8squared=64
18squared=256
64+256=320
320 (radical)
17.89 m
11. If 9m - 3 = -318, then 14m = ?
a. -28
b. -504
c. -329
d. -584
e. -490
Answer:
e. -490
Step-by-step explanation:
-318+3= -315
-315/9= -35
So that would mean m= -35
-35*14= -490
