Efficient manufacturing: Efficiency experts study the processes used to manufacture items in order to make them as efficient as
possible. One of the steps used to manufacture a metal clamp involves the drilling of three holes. In a sample of 85 damps, the
mean time to complete this step was 50.5 seconds. Assume that the population standard deviation is 0 - 12 seconds. Round the
critical value to no less than three decimal places.

Answer:

XV = 4.75

Step-by-step explanation:

TV/WV = UV/XV (similarity theorem)

TW = 9

WV = 3

UV = 19

TV = 9 + 3 = 12

XV = ?

Plug in the values

12/3 = 19/XV

4 = 19/XV

XV × 4 = 19

XV = 19/4

XV = 4.75

Step-by-step explanation:

We already have the lengths of the given sides:

17+5=22

22+11=33

33+7=40

40+(5+11)=56

The measures of the angles in triangle UVW are shown in the diagram below:
A. 21
B. 39
C. 45
D. 126

Answers

Answer:

D. 126

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

30 + 24 + 3x - 9 = 180 add like terms

45 + 3x = 180 subtract 45 from both sides

3x = 135 divide both sides by 3

x = 45 and to find angle UVW replace x with 45

3*45 - 9 = 126

bricks having volume 500cm^3 each are selected to construct a compound wall of 200m×0.5m×1.5.If theprice of the brick is Rs.14,find the total price.​

Answers

Answer:

Rs. 4,200,000

Step-by-step explanation:

Given :

Volume of brick = 500cm³

Dimension of wall : 200m×0.5m×1.5m

Converting to cm

Volume of compound wall:

(200 * 100) * (0.5 * 100) * (1.5 * 100)

20000cm * 50cm * 150cm=

= 150000000cm³

Volume of compound wall / volume of brick

1500000000 cm³ / 500 cm³

= 300000

Price per brick = Rs. 14

Total price = 14 * 300000 = Rs. 4,200,000

Determine the number of different ways to draw two cards of the same rank when
drawing two cards from a 60-card deck (assume that there are 4 cards in each rank).

Answers

Answer:

Step-by-step explanation:

The number of different ways to draw two cards of the same rank will be 1/195.

What is probability?

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

A 60-card deck (assume that there are 4 cards in each rank).

Then the total number of events is given as,

Total event = ⁶⁰C₂

Total event = 60! / [(60 - 2)! x 2!]

Total event = (60 x 59) / 2

Total event = 1,170

The number of the favorable event will be given as,

Favorable event = ⁴C₂

Favorable event = 4! / [(4 - 2)! x 2!]

Favorable event = (4 x 3) / 2

Favorable event = 6

Then the probability is given as,

P = 6 / 1,170

P = 1/195

The product of (3 - 4i) and ____ is 25.

Answers

Answer:

( 3 + 4i )

Step-by-step explanation:

For this problem, we need to know that i^2 = -1. With this, let's solve the multiplication problem.

So to get rid of the i, we know it needs to be squared. The question is, for the sun of the products do we have a -4i or a +4i? So we will test both.

( 3 - 4i )^2 ?= 25

( 3 - 4i )( 3 - 4i ) ?= 25

9 - 12i - 12i - 16 ?= 25

We can stop here since we know that 24i will never equal 25.

So let's try the -4i

( 3 + 4i )( 3 - 4i ) ?= 25

9 + 12i - 12i + 16 ?= 25

9 + 16 ?= 25

25 == 25

Thus, our term for this to be true is ( 3 + 4i ).

Answer:

x = √7

Step-by-step explanation:

First find the missing angle of the triangle with the side as 5, and the hypotenuse as 6.

a² + b² = c²

5² + b² = 6²

25 + b² = 36

b² = 11

b = √11

So now we know that for the triangle with sides 2 and x, the hypotenuse is √11. Now use the Pythagorean Theorem to find x.

a² + b² = c²

2² + x² = (√11)²

4 + x² = 11

x² = 7

x = √7.
