How do u do this??????
natali 33 [55]
F(x^2) = x^2 - 3

5f(x^2) = 5x^2 - 15 = 2x - 8

Placing all the terms on the left side, we get:

5x^2 - 2x - 7 = 0 which factorises to

(5x - 7)(x + 1) = 0

So, x = 7/5 or x = -1

But x is non-negative, so x = 7/5 = 1 2/5

C is the answer.

According to government​ data, the probability that an adult was never in a museum is​ 15%. in a random survey of 10​ adults, wh
CaHeK987 [17]
<span>Let p be the probability that an adult was never in a museum. Hence p = 0.15. Then q is the probability that an adult was in a museum is 1 - 0.15 = 0.75. We have a binomial expansion where the probability of k success in n trials is given by P_n(k) = (n, k) p^(k) q^(n -k) where (n, k) is the number of ways to select 10 objects from k things. At least two or fewer means we have P_10 (< or equal to 2) So we have P_10 (less than or equal to 2) = P_10 ( 0) + P_10 (1) + P_10 (2). So we have P _10 (0) = ( 10, 0) (0.15)^ (0) (0.75)^(0) = 0.196. For P_10(1), we have 0.3474 and for P_10(2), we have 0.2758. Adding these we have 0.1960 + 0.3474 + 0.2758 = 0.8192.</span>

<span>For this case, what you must do is find the area of the two rectangles shown in the figure.</span>

<span> We have then:</span>

<span> Rectangle 1:</span>

<span> A1 = (40) * (18)</span>

<span> A1 = 720</span>

<span> Rectangle 2:</span>

<span> A2 = (24-18) * (40-30)</span>

<span> A2 = (6) * (10)</span>

<span> A2 = 60</span>

<span> The area of the composite figure is:</span>

<span> A = A1 + A2</span>

<span> A = 720 + 60</span>

<span> A = 780 feet ^ 2</span>

<span> Answer:</span>

erma4kov [3.2K]

Answer: The 36th caller will be the first one to win both

Step-by-step explanation:

Given: A radio station is having a promotion in which every 12th caller receives a free concert ticket and every 9th caller receives a limo ride.

To find which caller would be the first one to win both, we will find the LCM.

Prime factorization of 9 and 12:

12 = 3x 2x 2

9 = 3x 3

LCM(12,9)=3\times2\times2\times3=36  [Where LCM=Least common multiple]

Therefore, the 36th caller will be the first one to win both.
