Answer:

The width of the window should be $7.6\ ft$ and the height of the window should be $3.8\ ft$

Step-by-step explanation:

we know that

The circumference of a semicircle (window) is equal to

$C=\pi r$

we have that

$C=12\ ft$

$\pi=3.14$

substitute and solve for r

$12=(3.14)r$

$r=12/3.14=3.8\ ft$

the width of the window is equal to the diameter of the semicircle

The width of the window should be $3.8*2=7.6\ ft$ and the height of the window should be $3.8\ ft$

lora16 [44]

Answer:

small boxes= 15

large boxes = 5

Step-by-step explanation:

let the number of large boxes be denoted as

Then the number of small boxes is 3 time that of large boxes, i.e.

If the total volume of all boxes is 235 cubic feet,

Then, we can form the following relationship (equation)

17*x+10*(3x)=235

x=5

Therefore the number of large boxes is 5

and that of small boxes is

3*5=15

In each turn of a game you toss two coins. if 2 heads come up, you win 2 points and if 1 head comes up you win 1 point. if no he

Blizzard [7]

The expected value of the number of points for each turn is 0.25

<h3>What is expected value?</h3>

Expected value describes the long term average level of a random variable based on its probabilty distribution.

Now, Probability that 2 heads come up is

P(2 is H) = 1/4

Probability that 1 heads come up is

P(1 is H) = 2/4

⇒P(1 is H) = 1/2

Probability that no head will come up

P(no H's) = 1/4

Hence, the expected value for winning of 2points, 1point and lose of3 points is given as-

Expected value = 2 * P(2 is H) + 1 * P(1 is H) - 3 * P(no H's)

⇒Expected value = 2 * 1/4 + 1 * 1/2 - 3 * 1/4

= 0.5 + 0.5 - 0.75

⇒Expected value = 0.25

What’s the x and y intercept of 8x+5y=-48

Anuta_ua [19.1K]

Step-by-step explanation:

$8x + 5y = - 48 \\ \\ at \: x = 0 \\ \\ 8 \times 0 + 5y = - 48 \\ \\ \therefore \: 5y = - 48 \\ \\ \therefore \: y = \frac{ - 48}{5} \\ \\ \therefore \: y - intercept = - 9.6 \\ \\ at \: y = 0 \\ \\ 8 x + 5 \times 0 = - 48 \\ \\ \therefore \:8x = - 48 \\ \\ \therefore \: x = \frac{ - 48}{8} \\ \\ \therefore \: x - intercept = -6 \\ \\$
