What is the solution to the problem expressed to the correct number of significant figures? 15. 11 (142 × 16. 5) = ? A. 2,358 B.

olchik [2.2K]

The solution to the problem expressed 2358.

<h3>What is the meaning of significant figure?</h3>

Significant figure It is defined as the minimum number of digit us needed to express a number in scientific notation.

Therefore we get,

$15.11+(142\times16.5)$

First we have to multiply the given digits as per rule.

$=15.11+2343$

Now we will add both the digits, we get

$=2358.11$

As per given expression, we conclude that the number of significant figure is 4.

So, the answer will be, 2358.

Therefore, the correct option is, 2358.

12 yellow balls and 9 red balls are placed in an urn. Two balls are then drawn in succession without replacement. What is the pr

denis23 [38]

Answer:

$\frac{9}{35}$

Step-by-step explanation:

When the first draw is done there are 9 red balls in a sample size of 21. So there probability of drawing a red ball will be $\frac{9}{21}$

When the second draw is done, there will be 12 yellow balls in a sample size of 20 since the first ball will not have been replaced into the bag. So the chance of someone drawing the second ball in the second draw is $\frac{12}{20}$

The probability of them happening in this order is the product of both probabilities:

$\frac{9}{21} * \frac{12}{20} = \frac{9}{35}$

Translate the sentence into an equation using n as the unknown number. Then solve the equation for n

Gelneren [198K]

Answer:

$5+\frac{n}{2}=11$

$n=12$

Step-by-step explanation:

<u><em>The correct question is</em></u>

Translate the sentence into an equation using n as the unknown number. Then solve the equation for n.

5 increased by half a number is 11

Let

n ----> the unknown number

we know that

The linear equation that represent this situation is

$5+\frac{n}{2}=11$

solve for n

Multiply by 2 both sides

$10+n=22$

subtract 10 both sides

$n=22-10$

$n=12$

1. Define the following: Odds ratio Relative risk 2. Describe how to calculate the Odds ratio and provde the formula. 3. Describ

igor_vitrenko [27]

Answer and Explanation:

Odds ratio is the odds that an outcome would happen given a level of exposure in comparison to the occurrence of that outcome without exposure. Odds ratio is calculated by dividing odds of event occurring with exposure(the first group) by odds of event(usually disease) occurring without exposure. Odds is different from probability(denoted p/1-p). While probability is the number of favorable events divided by total number of events, odds is number of favorable events/number of unfavorable events.

Relative risk, also measuring relationship between exposure and outcome, is the ratio of the probability that an outcome would occur without exposure and probability that an outcome would occur with exposure.
