C and D are mutually exclusive events. Find P(C or D).<br> P(C)= 3/7= P(D)= 4/7<br> P(C or D)
IgorLugansk [536]

Answer:

P(C\ or\ D) = 1

Step-by-step explanation:

Given

P(C) = \frac{3}{7}

P(D) = \frac{4}{7}

Required

P(C\ or\ D)

Since the events are mutually exclusive, then:

P(C\ or\ D) = P(C) + P(D)

So, we have:

P(C\ or\ D) = \frac{3}{7} + \frac{4}{7}

Take LCM

P(C\ or\ D) = \frac{3+4}{7}

P(C\ or\ D) = \frac{7}{7}

P(C\ or\ D) = 1

April shoots an arrow upward at a speed of 80 ft/sec from a platform of 25 ft. High. The pathway of the arrow can be represented
soldi70 [24.7K]

Answer:

125feet

Step-by-step explanation:

Given the equation that modeled the height expressed as h = -16t^2 + 80t + 25, where h is the height and t is the time in seconds.

The arrow reaches the maximum height at dh/dt = 0

dh/dt = -32t + 80

0= -32t+80

32t = 80

t = 80/32

t = 2.5secs

substitute t = 2.5 into the formula;

h = -16t^2 + 80t + 25

h = -16(2.5)^2 + 80(2.5) + 25

h = -16(6.25)+225

h = -100+225

h = 125

Hence the maximum height the arrow reaches is 125feet

An online test of English spelling looked at how well people spelled difficult words. The bar graph to the right shows how many
sweet-ann [11.9K]

Answer:

60 ; 5220

Step-by-step explanation:

A) From the horizontal bar chart provided, it could be inferred that 85 people spell the word 'weird' correctly. The graph is scaled on a fixed interval of 10. Hence, the midpoint of 10 = 5

(80 + 5) = 85

B) In a group consisting of 8719 randomly selected people estimate how many more people can correctly spell weird than inoculate

From the graph :

85 per 100 could spell weird correctly while,

About 25 per 100 could spell inoculate correctly.

Difference In number per 100 people

(85 - 25) = 60 people per 100

We could round 8719 to the nearest 100 = 8700

Number of 100's in 8700 = 8700/100 = 87

(87 × 60) = 5,220 people
