Mutually exclusive events are events that cannot occur at the same time. So the answer is yes because the two events can happen at the same time. In the first event, it is random - it can be female or male and in the second event it is the only male.

X and y vary inversely and x=50 when y=5 find y when x=10 what is k?

Kisachek [45]

Answer:

Part A)

1) $k=250$

2) $y=25$

Part B)

1) $k=7$

2) $y=84$

Step-by-step explanation:

Part 1) x and y vary inversely and x=50 when y=5 find y when x=10 what is k?

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

step 1

<u>Find the value of k</u>

x=50 when y=5

substitute the values

$y*x=k$ ------> $5*50=k$ -----> $k=250$

The equation is equal to

$y*x=250$ or $y=250/x$

step 2

<u>Find y when x=10</u>

substitute the value of x in the equation and solve for y

$y*(10)=250$

$y=250/10=25$

Part B) x and y vary directly and x=6 when y=42 find k what is y when x=12

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

step 1

<u>Find the value of k</u>

x=6 when y=42

substitute the values

$y/x=k$ ------> $42/6=k$ -----> $k=7$

The equation is equal to

$y/x=7$ or $y=7x$

step 2

<u>Find y when x=12</u>

substitute the value of x in the equation and solve for y

$y=7(12)=84$

9. Find the volume of the triangular pyramid. (2pts)-10 mI9 m16 m

Makovka662 [10]

Answer:

240 m³

Explanation:

The volume of a pyramid is equal to:

$V=\frac{1}{3}\times B\times H$

Where B is the area of the base and H is the height of the pyramid.

Then, the base of the pyramid is a triangle, so the area of a triangle is equal to:

$B=\frac{b\times h}{2}$

Where b is the base of the triangle and h is the height of the triangle. So, replacing b by 16 m and h by 9 m, we get:

$B=\frac{16\times9}{2}=\frac{144}{2}=72m^2$

Finally, replacing B by 72 m² and H by 10 m, we get that the volume of the pyramid is equal to:

$V=\frac{1}{3}\times72\times10=\frac{1}{3}\times720=240m^3$

Therefore, the volume is 240 m³
