Answer:

0.6603 = 66.03% probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Sent by ABC Speedy Delivery Service.

Event B: Arrived on time.

The probability that any given parcel will be sent by the ABC Speedy Delivery Service is 0.71.

This means that [tex]P(A) = 0.71[/tex]

The probability that the parcel will arrive on time given the ABC Speedy Delivery Company was used is 0.93.

This means that [tex]P(B|A) = 0.93[/tex]

Find the probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.

This is [tex]P(A \cap B)[/tex]. So

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

[tex]P(A \cap B) = P(B|A)*P(A) = 0.93*0.71 = 0.6603[/tex]

0.6603 = 66.03% probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.

Answer:

Rate of the boat in still water 73 mi/hr

Rate of the current 18 mi/hr

Step-by-step explanation:

Calculation to determine the rate of the boat in still water and the rate of the current

Let B represent the speed of the boat in still water.

Let S represent the speed of the stream

Speed upstream = B-S.

Speed downstream = B+S.

Using the equation for distance

Distance=Rate * Time

Upstream

(B-S)7 = 385

(B+S)5= 455

Simplify first:

B-S=385/7

B-S = 55

B+S=455/5

B+S = 91

Solve by elimination. Add the two equations.

2B=55+91

2B = 146

B=146/2

B = 73 mi/hr

Substitute this into either equation and solve for S.

B+S = 91

73+S = 91

S=91-73

S = 18 mi/hr

Therefore the rate of the boat in still water is 73 mi/hr and the rate of the current is 18 mi/hr

Answer:

A 90% confidence interval for the mean number of letter sounds identified in one minute is: (30.84, 37.34).

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.9}{2} = 0.05[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.05 = 0.95[/tex], so Z = 1.645.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.645\frac{23.44}{\sqrt{141}}[/tex]

[tex]M = 3.25[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 34.09 - 3.25 = 30.84.

The upper end of the interval is the sample mean added to M. So it is 34.09 + 3.25 = 37.34.

A 90% confidence interval for the mean number of letter sounds identified in one minute is: (30.84, 37.34).

Probability the next chew will be orange or lime: 13/24

Answer:

4 or 5 ft

Step-by-step explanation:

Answer:

2.1 mmHg

Step-by-step explanation:

The confidence is given by:

Mean ± margin of error

Confidence interval = (110.7 ; 114.9)

Mean = 112.8

Lower boundary = 110.7

Taking the lower boundary :

Lower boundary = mean - margin of error

110.7 = 112.8 - margin of error

Margin of Error = 112.8 - 110.7

Margin of Error = 2.1

Hey! Sorry im too late lol but here-

Step-by-step explanation:

Example of tangent in the real world-

When a stone gets tied at one end of a string & the other end is rotated, then the stone will form a circle.

How you know the tangent and radius are perpendicular:

The radius is formed vertically and is completely straight, while the tangent is completely straight but horizontal. You can draw a right triangle angle between the radius and tangent line by adding a third line, and a right angle is 90 degrees. So, this forms a perpendicular line.

Hope this helped :))

Part A: The path of the ball in relation to the curved path of the thrower

Part A: The path the ball takes is perpendicular to the hand, bat or feet  at the point of last contact

Reason for the selection:

Part A

A real world example of tangents is the direction of a ball immediately it is released and the circular path of the motion, that provides the force input that is given to the ball to cause it to move in the required direction

The tangent is the path the ball takes immediately it is moving without contact to the bat, hand or feet that causes it to move

The circular path is the motion of the hand, leg, bat or feet that makes before the ball is released

The radius is the hand, leg, or bat that rotates in a circular path, so as to move the ball

Part B

How the radius is perpendicular to the tangent

The radius, such as the leg kicking a ball is perpendicular to the tangent of the which is the path of the ball because a kick to send the ball into air, the orientation of leg at the point the ball leaves is perpendicular to the angle of elevation with which the ball is launched

Answer:

A) 0.36 with a line over both 36 means as a decimal the 36 repeats, so it would look like 0.363636

as a fraction it would be 36/99, divide both numbers by 9 to get 4/11

B) 0.36 with the line over the 6 means just the 6 repeats so it would look like 0.3666

as a fraction that would be 33/90 , divide both by 3 to get 11/30

C) 0.36 would be 36/100, divide both numbers by 4 to get 9/25

Answer:

x=48

Step-by-step explanation:

You start with the values of 4 and 16. Figure out how many times 4 goes into 16, which is 4. (4*4=16)

Now, since 4 is multiplied by itself to reach the value of 16, 12 will also be multiplied by 4 to give you the value of x.

The perimeter is 26cm

Step-by-step explanation:

Given

See attachment for shape

Required

The perimeter

This implies that, we add up the length of all sides (see attachment 2 for complete lengths)

So, we have:

[tex]Perimeter = 6cm + 4cm + 2cm + 3cm + 4cm + 7cm[/tex]

[tex]Perimeter = 26cm\\[/tex]

Answer:

w = 4 and l = 9 or

l = 4 and w = 9

Step-by-step explanation:

let l = length

let w = width

2l + 2w = 26

lw = 36

l = 36/w

2(36/w) + 2w = 26

72/w + 2w = 26

(72 + 2w²) ÷ w = 26

cross-multiply:

2w² + 72 = 26w

2w² - 26w + 72 = 0

factor:

2(w² - 13w + 36) = 0

2(w - 4)(w - 9) = 0

w = 4 and l = 9 or vice versa
