The probability of a randomly selected adult in one country being infected with a certain virus is 0.005. In tests for the viru

myrzilka [38]

Answer:

The probability is 12.66%.

This is a low probability, so it is unlikely for such a combined sample to test positive.

Step-by-step explanation:

If the probability of being infected is 0.005, the probability of not being infected is 0.995.

Then, to find the probability of at least one of the 27 people being infected P(A), we can find the complementary case: all people are not infected: P(A').

$P(A') = 0.995^{27}$

$P(A') = 0.8734$

Then we can find P(A) using:

$P(A) + P(A') = 1$

$P(A) = 1 - 0.8734$

$P(A) = 0.1266 = 12.66\%$

This is a low probability, so it is unlikely for such a combined sample to test positive.

8. a. If A is 5 x 5 matrix and det(A) = 3 then det(2A) = --------- b. If A is 100 x 100 matrix and det( A) = m then det(-A) = --

cricket20 [7]

Answer:

a) det(A)=96; b) det(A)=m;

Step-by-step explanation:

If we have a $n \times n$ matrix A and a constant $t \in \mathbb{R}$ . It holds that $\det(tA)=t^n\det(A)$ , hence

(a) If A is a $5x5$ matrix and $\det(A)=3$ , then we have

$\det(2A)=2^5\cdot \det(A)= 32 \cdot 3=96$

(b) If A is $100 \times 100$ matrix and $\det(A)=m$ , then we have

$\det(-A)=(-1)^{100}\det(A)=(-1)^{100}\cdot m=1 \cdot m = m$

Select the correct answer.

malfutka [58]

Answer:

C. $x=7$

Step-by-step explanation:

So we know that a vertical line is represented by $x=$ so we can already rule out two of the options. We also know that since the line runs vertically, all points will start with the same $x$ coordinate. This means that the correct answer is $x=7$
