7 x 5 = 35
35 x 12 =420
Answer:420
(1/2)x + 4 is the expression
First part, in quadrilateral WXYZ, WX is parallel to ZY because both sides are equal while the other parallel segments WZ and XY are equal but different side lengths.
The measure of angle Z is 78 because both of the pictures are the same, only rotated. and angle S and Z are acute.
Answer:
(2,4), (6,4), (2,-2), (6,-2)
Step-by-step explanation:
To dilate a figure multiply 2(x,y)
2(1,2) = (2,4)
2(3,2) = (6,4)
2(1,-1) = (2,-2)
2(3,-1) = (6,-2)
Hope this helps! Ξ
Answer:
0.0818.
Step-by-step explanation:
This question can be solved using the binomial theorem because the probability of success is fixed.
Total adults = n = 20
Required attempts = r = 12
Probability of success = p = 3/4 = 0.46
Binomial Theorem formula:
P(X=r) = nCr * p^r * (1-p)^(n-r).
Substituting the values:
P(X=12) = 20C12 * 0.46^12 * (1-0.46)^8
P(X=12) = 125970 * 0.46^12 * (0.54)^8 = 0.0818 (to the nearest 3 significant figures).
So the probability that exactly 12 people use their smart phones in meetings or classes out of 20 is 0.0818!!!
