tigry1 [53]

Answer: 31,365

Step-by-step explanation:

Given : The number of horror films = 15

The number of comedies = 18

Then , the number of different combinations of 4 movies can he rent if he wants at least two comedies is given by :-

$^{18}C_2\times ^{15}C_2+^{18}C_3\times ^{15}C_1+^{18}C_4\times ^{15}C_0\\\\=\dfrac{18!}{2!(18-2)!}\times\dfrac{15!}{2!(15-2)!}+\dfrac{18!}{3!(18-3)!}\times\dfrac{15!}{1!(15-1)!}+\dfrac{18!}{4!(18-4)!}\times\dfrac{15!}{0!(15-0)!}\\\\=16065+12240+3060=31365$

Hence, the number of different combinations of 4 movies can he rent if he wants at least two comedies = 31,365

Step-by-step explanation:

$m \angle DBE = \frac{1}{2} \{m (arc\: AC) + m (arc\: DE) \} \\ \\ = \frac{1}{2} (130 \degree + 40 \degree) \\ \\ = \frac{1}{2} \times 170 \degree \\ \\ \huge \purple{ \boxed{\therefore m \angle DBE = 85\degree}}$

Hence, option A 85° is the correct answer.

First you find how much the shape has dilated. To d ok that you divide the size of the size already given to you from the bigger shape from the same did if the smaller shape. So 58÷6=9.7. The shape grew by 9.7. To find x you use the similar side of the other shape again and multiy that size by 9.7. So 9.7×3=29.1

x=29.1
