We can see the ratio of a side big figure and small figure is 60:15 or 60/15 = 1/4.

In decimal form we can write 1/4 as 0.25.

Therefore, scale factor is 0.25.

So, second option is applicable. Please check second option :

<h3>The scale factor is 0.25.</h3>

Now, let us find the side A by multiplying by scale factor 0.25 of the big figure.

The corresponding side of A is 35.

Therefore, A is 0.25 × 35 = 8.75 cm.

Therefore, other applicable option is 3rd option.

<h3>The length of side A is 8.75 cm.</h3>

IRISSAK [1]

Answer:

27° = no answer or stays the same (not to sure on this one)

20' = 0.3°

58" = 0.0161°

Step-by-step explanation:

A minute = 1/60

A second = 1/3600

0 + 0 x 1/60 + 58 x 1/3600

A system has two components: A and B. The operating times until failure of the two components are independent and exponentially

LuckyWell [14K]

Answer:

$E(x) = \frac{1}{2}$ -- Component A

$E(x) = \frac{1}{3}$ -- Component B

Step-by-step explanation:

Given

Distribution = Exponential

$\lambda = 2$ --- Component A

$\lambda = 3$ --- Component B

Solving (a): The mean time of A

The mean of an exponential distribution is:

$E(x) = \frac{1}{\lambda}$

We have:

$\lambda = 2$ --- Component A

$E(x) = \frac{1}{2}$

Solving (b): The mean time of B

The mean of an exponential distribution is:

$E(x) = \frac{1}{\lambda}$

We have:

$\lambda = 3$ --- Component B

$E(x) = \frac{1}{3}$

Mr. And Mrs. Doran have a genetic history such that the probability that a child being born to them with a certain trait is 0.14

poizon [28]

Answer:

0.938

Step-by-step explanation:

From the question :

p = 0.14

Number of children, n = 7

P(x ≤ 2) = P(2) + P(1) + P(0)

Using binomial probability :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

We could also use the binomial probability calculator :

P(x ≤ 2) = 0.3479 + 0.3965 + 0.1936

P(x ≤ 2) = 0.938

X squared divided by -10 =2<br> what is

lesya [120]

Hey there!

The answer to your question is ± 12

To solve the equation x²/-10 = 2, first multiply 10 to both sides:

x² = 20

Then, take the square root from both sides:

x = ± 20
