It takes 10.9 hours.

We set the equation equal to 1792000:

1792000=3600(2)^{\frac{t}{73}}

Divide both sides by 3600:
\frac{1792000}{3600}=\frac{3600(2)^{\frac{t}{73}}}{3600}
\\
\\\frac{4480}{9}=2^{\frac{t}{73}}

We will use logarithms to solve this:
\log_2{\frac{4480}{9}}=\frac{t}{73}

Multiply both sides by 73:
73\log_2{\frac{4480}{9}}=t
\\
\\654.03=t

This is in minutes; to convert to hours, divide by 60:
654.03/60 = 10.9

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
