Answer: A. I only

Step-by-step explanation:

Most of the observations are on the lower end, so the distribution is skewed right. The interquartile range is indicated by the length of the box, about 14. The median is indicated by the vertical line running through the box, about 13

3) Find the value of FD. bited F 12 12 13x - 16 E 4x+11 D

vlada-n [284]

The Length of FD = 26 cm

According to the given information

FE = FC = 12cm

As FE, FC both are radius of circle

The tangent segments to a circle from a external point are equal

Hence

CD = ED

13x - 16 = 4x + 11

13x - 4x = 11 + 16

9x = 27

x = 27/9

x = 3

CD = 13x - 16

= 13 × 3 - 16

= 23 cm

ED = 4x + 11

= 4 × 3 + 11

= 23 cm

In Triangle FED

FE is perpendicular to ED

According to Pythagoras Theorem

$FD^{2}= FE^{2}+ED^{2}$

= $12^{2}+ 23^{2}$

= 673

FD = 26 cm approx.

The Length of FD = 26 cm

If 26.97 ÷ 6.3 is written in long division form as so that the divisor is written as a whole number, where should the decimal po

Soloha48 [4]

<h2>Answer:</h2>

The decimal point should be placed between digits 9 and 7 in the dividend. i.e the dividend becomes 269.7

<h2>Step-by-step explanation:</h2>

Dividend = 26.97 [numerator]

Divisor = 6.3 [denominator]

If 26.97 ÷ 6.3 is written in long division form so that the divisor is written as a whole number, we have the following;

(i)First convert the divisor to a whole number by multiplying by 10 i.e

6.3 x 10 = 63

(ii) Since the divisor (denominator) has been multiplied by 10, to make sure the division expression stays the same, we need to multiply the dividend(numerator) too by 10. i.e

26.97 x 10 = 269.7

(iii) The division expression then becomes;

269.7 ÷ 63

Therefore, the decimal point should be placed between digits 9 and 7 in the dividend.

In a semiconductor manufacturing process, three wafers from a lot are tested. Each wafer is classified as pass or fail. Assume t

Angelina_Jolie [31]

Answer:

$P(X = 0) = 0.027$

$P(X = 1) = 0.189$

$P(X = 2) = 0.441$

$P(X = 3)= 0.343$

Step-by-step explanation:

The probability mass function P(X = x) is the probability that X happens x times.

When n trials happen, for each $x \leq n$ , the probability mass function is given by:

$P(X = x) = pe_{n,x}.p^{x}.(1-p)^{n-x}$

In which p is the probability that the event happens.

$pe_{n,x},$ is the permutation of n elements with x repetitions(when there are multiple events happening(like one passes and two not passing)). It can be calculated by the following formula:
