The answer is 105 because 180-75=105
P(roll a 4) = 8/40. It is 8/40 because you rolled the a 4 eight times out of the forty tries. Hope this helps!
Answer:
C. 12m
Explanation:
Let the length of the shorter arm = x
Since the length of the longer arm is equal to twice the length of the shorter arm;
• The length of the longer arm = 2x
• The area of triangle ABD = 18√3 m².
Given a triangle with two sides and the included angle, the area of the triangle is calculated using the formula below:
Therefore:
We solve for x.
Multiply x by 2 to get the length of the longer arm:
The length of the longer arm is 12m.
C is the correct option.
Answer:
x=−8+√86 or x=−8−√86
or
344
Step-by-step explanation:
Let's solve your equation step-by-step.
x2+16x=22
Answer:
The required probability is 0.034.
Step-by-step explanation:
Consider the provided information.
An urn contains seven red marbles, four white marbles, and five blue marbles.
Red marbles = 7
White marbles = 4
Blue marble = 5
Total number of marbles = 7+4+5 = 16
Three marbles are drawn in succession.
Probability that the first marble is red, the second is white, and the third is blue is:
Hence, the required probability is 0.034.
