Answer:

  y ≥ 1/4x + 2

Step-by-step explanation:

The line is solid, and the shading is above it, so the inequality will have a form similar to ...

  y ≥ [the boundary line]

The y-intercept is y = 2, and the slope is 1 unit up for 4 units right, so 1/4. In slope-intercept form, the equation of the boundary line is ...

  y = mx + b . . . . . . for slope m and y-intercept b

This boundary line has equation ...

  y = 1/4x + 2

So, the inequality is ...

  y ≥ 1/4x + 2

1 7/10 x 2/3 what is the product
Ludmilka [50]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{1 \frac{2}{15}}}}}}

Step-by-step explanation:

\sf{1 \frac{7}{10}  \times  \frac{2}{3} }

Convert the mixed number into improper fraction

\longrightarrow{ \sf{ \frac{10 \times 1 + 7}{10}  \times  \frac{2}{3}}}

\longrightarrow{ \sf{ \frac{17}{10}  \times  \frac{2}{3}}}

To multiply one fraction by another, multiply the numerators for the numerator, and multiply the denominator for its denominator and reduce the fraction obtained after multiplication into lowest term

\longrightarrow{ \sf{ \frac{17 \times 2}{10 \times 3}}}

\longrightarrow{ \sf{ \frac{34}{30}}}

\longrightarrow{ \sf{ \frac{17}{15} }}

Convert the improper fraction into mixed number

\longrightarrow{ \sf{1 \frac{2}{15} }}

Hope I helped!

Best regards! :D

What is the probability of choosing a 12-person jury with 7 or 8 women? In other words, calculate P(7 or 8 women).
Yanka [14]

Answer:

1/6 chance

Step-by-step explanation:

There are 12 possible outcomes, so 12 goes in the denominator.

There are 12 vacant spots in the jury, and the outcomes are only favorable if 7 or 8 of them are taken by women.

To find a probability, it is favorable outcomes/total outcomes. In this case, it is a 2/12 probability because there are two favorable outcomes, 7 and 8, and 12 total outcomes. Simplify 2/12 into 1/6, and that's your answer.
