In a New York Times/CBS News Poll, respondents were asked if it should be legal or illegal to send a text message while driving.

AnnZ [28]

Answer: $\dfrac2{201}$

Step-by-step explanation:

Number of persons said it is legal to text while driving = 8

Number of persons said it is illegal to text while driving = 804

Total persons sampled = 804+8 = 812

Since probability = $\dfrac{\text{favorable outcomes}}{\text{Total outcomes}}$

The probability of randomly selecting someone who believes it should be legal to text while driving = $\dfrac{8}{804}=\dfrac2{201}$

Required probability = $\dfrac2{201}$

Find the width of a rectangle 25 feet and the perimeter is 80

lukranit [14]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - a rectangle with length 25 feet and perimeter 80 feet

To calculate - width of the rectangle

We know that ,

$\bold{Perimeter \: of \: rectangle = 2(l + b)} \\$

where b = width / breadth of rectangle

‎ ‎ ‎

substituting the values in the formula stated above ,

$\bold{80 = 2(25 + b)} \\ \\\bold{ \implies \: 25 + b = \cancel \frac{80}{2} } \\ \\ \bold{\implies \: 25 + b = 40 }\\ \\ \bold{\implies \: b = 40 - 25 }\\ \\\bold{ \implies \: b = 15 \: feet}$

0.037 in scientific notation

Sedaia [141]

$\huge\boxed{3.7\ \times\ 10^{-2}}$

First, you need to find where you can move the decimal point to so that there is only one non-zero digit to the left of it.

Move the decimal point, and that is the first part done.

Add " $\times\ 10$ ".

For the last part - the power, you need to find how many decimal places you moved the decimal point. In this case, we moved it to the right 2 places, so the power is $^{-2}$ .

If, for example, we had moved the decimal point three places to the left, the power would be $^{3}$ .
