<h3>
Total 73 times we can expect white or gray marbles.</h3>
Step-by-step explanation:
Total number of marbles = 33
Number of white marbles = 6
Number of gray marbles = 5
Now, as we need to pick white or gray marbles, so favorable outcomes
= 6+ 5 = 11 marbles
Now, P(Picking out 1 white or gray marble) = 
Here, the same experiment is repeated 220 times.
So, the Combined Prediction
= Probability at first attempt x Number of repetitions

⇒The combined prediction after 220 attempts = 73
Hence, total 73 times we can expect white or gray marbles.
Answer:
y = -5x + 8
Step-by-step explanation:
Equation of a line: y = mx + b
x = slope
b = y-intercept or starting point
Slope = y^2 - y^2/x^2 - x^1
Slope = -12 - 43/4 - (-7)
Slope = -55/11
Slope = -5
b = y - y^1 = m(x - x^1)
b = y - 43 = -5(x - (-7))
b = y - 43 = -5x - 35
Add 43 to both sides
y = -5x + 8
Answer:
solution :
in the given figure AB=10.2cm, AC=14cm, AD=DC and AD perpendicular to BC.
now ,
in rt angle tirangle ADC,
angleACD=45 degree, angle DAC=45 degree now,
in triangle ABD,
angle BAD+angleABD+angleADB=180 DEGREE (sum of the sngle of triangle)
angle BAD+75+30=180
angle BAD=180-165 therefore,angle BAD=15
angle BAC =15+45=60
Area of triangle ABC=1/2×AB×AC×SIN 60
=1/2×10.2×14×√3/2
=61.83cm³ ans
Answer:
8x³y³
Step-by-step explanation:
When the number is in parentheses, it means the exponent goes to all of the variables and numbers inside. So 2 squared is 8 and x squared and y squared are just written like that. I hope this helps clear things up...
