Answer:
473/570
Step-by-step explanation:
No. of male = 365
No. of female = 570-365 = 205
No. of male with brown hair = 260
No. of female with brown hair = 108
the probability that a person was male or had brown hair = 365/570+108/570 = 473/570 [ for or case we add probabilities]
Answer:
Around 83% 473/ 570
Step-by-step explanation:
365 males + 108 females with brown hair = 473
Divide the number of outcomes desired by the total number of outcomes 473/570 = 0.829824....... = 82.98.....%

10. The dimensions of a triangular prism are shown in the diagram. 10 cm 10 cm www 8 cm 34 cm -12 cm What is the volume of the triangular prism in cubic centimeters?
Answer:
I dont understand, what does www mean?
Step-by-step explanation:
Uhm I would appreciate the length and height so I can solve.
Remember formula of a triangle is:
BH x 1/2
OK so 8 x 12 = 96
96 divided by 23 = 32
Your answer is 32 I am pretty sure if that's the following formula of a PRISM. Please wait for more responses if needed, thank you.
Without division:
8 x 12 = 96
Solve by factoring

Don't mind the ones in the negative when plotting just keep them in mind and use the bigger numbers, since the scale is big
Step-by-step explanation:
When putting a negate power you just inverse the equation while keeping the power the same and only changing the sign
i.e: 4^(-3)=1/4³

Step-by-step explanation:
5x + 7y = 25
5x - 2y = -65
solve using elimination
(step by step please)
5x+7y=25
5x-2y=-65
subtract both of the equations
5x-5x=0
7y--2y= 7y+2y=9y
25--65=25+65=90
0+9y=90
9y=90
divide both sides by 9 to get y by itself
9y/9=90/9
cross out 9 and 9 which becomes 1*1*y=y
90/9=10
y=10
find x by using the substitution method
5x+7y=25
5x+7(10)=25
5x+70=25
move +70 to the other side
sign changes from +70 to -70
5x+70-70=25-70
5x=-45
divide both sides by 5 to get x by itself
5x/5=-45/5
cross out 5 and 5 then becomes 1*1*x=x
-45/5=-9
x=-9
answer:
(-9,10)

Kyle held a balloon 8ft off the ground above his head and Ava is standing 15 feet directly to g the right of Kyle how far is Ava from the balloon
Answer:
17
Step-by-step explanation:
Pythagorean theory baby! Okay so the Pythagorean theory is a² + b² = c² so lets draw a triangle and label our sides. So we know 8² + 15² = c² so I'm going to find the square root of all of our numbers. We get 64 + 225 = c² so then add 64 + 225 = 289 then I take the square root of 289 which equals 17 . This answer also makes sense because out hypotenuse should always be bigger then the legs.
I'm pretty sure thats right, Hope this helps.
