Answer:
The perimeter is 110 cm.
Step-by-step explanation:
The length of a rectangle is 3x-5 and the width of the rectangle is 2x+7. Find the perimeter.
if we condense that
Perimeter = 2(Length) + 2(Width)
Now we can see how the answer forms. If we plug in our equations from above:
100 = 2(3x + 5) + 2(2x)
Distributing
100 = 6x + 10 + 4x
Answer:
C.)
Step-by-step explanation:
To simplify the expression, you need to:
1.) Rewrite
----->
2.) Distribute the exponents
-----> When an exponent is raised to another exponent, they should be multiplied
3.) Create common denominators
4.) Combine the variables
-----> When two variables with exponents are being multiplied, the exponents should be added
1.333
Step-by-step explanation:
slope =y2-y1
x2-x1.
slope =14-2
= 19-10
slope=12
=9
slope= 1.333
Answer:
0.164 = 16.4% probability that at least one color will be missing from the 10 selected balls.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Determine the probability that at least one color will be missing from the 10 selected balls.
Red missing:
Each time, there are 55 + 25 = 80 non-red balls, out of 100. So, in each of the 10 trials, 80% = 0.8 probability of not picking a red ball. The probability that no red ball is picked is given by:
(0.8)^10 = 0.1074
White missing:
55 + 20 = 75 non-white balls, out of 100, in each trial. The probability that no white ball is picked is given by:
(0.75)^10 = 0.0563
Blue missing:
45 non-blue balls, out of 100. The probability that no blue ball is picked is given by:
(0.45)^10 = 0.0003
Total:
0.1074 + 0.0563 + 0.0003 = 0.164
0.164 = 16.4% probability that at least one color will be missing from the 10 selected balls.
