What is the degree-measure of an angle travelled by the minute hand from 3:05pm to 3:50pm?
maria [59]

Answer:

270°

Step-by-step explanation:

We know that a full circle is 360°, the shape of a clock, and that the clock is divided into 12 different sections.

Our equation would be: 360 ÷ 12 = 30

3:05 is at the 1 hand and 3:50 is at the 10 hand. Subtract 1 from 10 and you get 9.

9 · 30 = 270, so our angle is 270°

I hope this helped, please mark Brainliest, thank you!

Solve the inequality: 3p - 16 < 20
Alekssandra [29.7K]

Isolate the p. First, add 16 to both sides

3p - 16 (+16) < 20 (+16)

3p < 36

Next, isolate the p. Divide 3 from both sides

3p/3 <36/3

p < 12

p < 12 is your answer

hope this helps

Answer:

67.20\%

Step-by-step explanation:

Given

n =2430 --- sample

r = 16.72\% --- degeneration rate

From the findings, we have:

p = 377 --- tested positive

t =561 --- total test

Required

The positive predicted value (PPV)

This is calculated using:

PPV=\frac{Positive}{Total}

i.e.

PPV = \frac{377}{561}

PPV = 0.6720

Express as percentage

PPV = 0.6720 * 100\%

PPV = 67.20
