The probability of drawing a blue card is 5/11 what is the probability of NOT drawing a blue card?

2 answers:

8 0

To get the probability of not drawing a blue card, you have to subtract 5 from 11 which is 6. So, the probability of not drawing a blue card is 6/11.

Solve for x. Round to the nearest tenth, if necessary. 1.8 & x

Valentin [98]

Answer:

x ≈ 1.4

Step-by-step explanation:

Using the sine ratio in the right triangle

sin50° = $\frac{opposite}{hypotenuse}$ = $\frac{RS}{RT}$ = $\frac{x}{1.8}$ ( multiply both sides by 1.8 )

1.8 × sin50° = x , then

x ≈ 1.4 ( to the nearest tenth )

What is the equation of the following line written in slope-intercept form?

dolphi86 [110]

Answer:

Option (2)

Step-by-step explanation:

Let the equation of the line is,

y - y' = m(x - x')

where (x', y') is a point lying on the given line.

And m = slope of the line = $\frac{y_2-y_1}{x_2-x_1}$

Line given in the graph passes through two points (-5, -1) and (-2, -3).

Slope of the line 'm' = $\frac{-3+1}{-2+5}$

= $-\frac{2}{3}$

Therefore, equation of the line passing through(-5, -1) and slope of the line = $-\frac{2}{3}$ will be,

y - (-1) = $-\frac{2}{3}[x-(-5)]$

$y+1=-\frac{2}{3}(x+5)$

$y=-\frac{2}{3}x-\frac{10}{3}-1$

$y=-\frac{2}{3}x-\frac{13}{3}$

Option (2) will be the answer.

Mr. Rives' rotating sprinkler waters his lawn up to a radius of 7 feet. What is the maximum number of square feet of lawn mr. Ri

zaharov [31]

Answer:

Step-by-step explanation:

Mr. Rives' rotating sprinkler waters his lawn up to a radius of 7 feet. The formula for determining the area of a circle is expressed as

Area = πr²

Where

π is a constant whose value is 3.14.

r represents the radius if the circle.

The area covered by one of Mr. Rives' rotating sprinkler would be

3.14 × 7² = 3.14 × 49 = 153.86ft²

Therefore, the maximum area of lawn that two sprinklers can cover would be

153.86 × 2 = 307.72 ft²

Find the radius of a circle with an area of 380 in².

Likurg_2 [28]

Answer:

11 inches

Step-by-step explanation:

The area of a circle can be found using:

$a=\pi r^{2}$

We already know that the area is 380, so we can substitute 380 in for a.

380= $\pi r^2$

Now, we need to find the radius. To do this, we need to get r by itself

First, divide both sides by pi

$380/\pi =\pi r^2/\pi$

120.95775675=r^2

Since r is being squared, we need to take the square root of both sides

$\sqrt{120.95775675}=\sqrt{r^2}$

10.9980796846=r

If we round to nearest whole number, our radius is 11 inches
