Please help me with these, find the missing side. Thank yu only if you know

abruzzese [7]

Answer:

7.48m (3s.f.)

Step-by-step explanation:

Let the missing side be x m.

Applying Pythagoras' Theorem,

x² +5²= 9²

x² +25= 81

x²= 81 -25 (-25 on both sides)

x²= 56

$x = \sqrt{56}$

$x = 2 \sqrt{14}$

x= 7.48 (3 s.f.)

∴ The missing side is 7.48 m (3s.f.)

M is the midpoint of line segment AB. If the coordinates of M are (2, 6) and the coordinates of B are (5, 10), which of the foll

Nitella [24]

Answer:

The coordinates are A(-1,2)

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

In this problem we have

$M(2,6)\\A(x_1,y_1)$

$B(x_2,y_2) ---> B(5,10)$

substitute the given values

$(2,6)=(\frac{x_1+5}{2},\frac{y_1+10}{2})$

Solve for $x_1$

$2=(x_1+5)/2\\4=x_1+5\\x_1=4-5=-1$

Solve for $y_1$

$6=(y_1+10)/2\\12=y_1+10\\y_1=12-10=2$

therefore

The coordinates are A(-1,2)

The starting salaries of individuals with an MBA degree are normally distributed with a mean of $40,000 and a standard deviation

zalisa [80]

Answer:

C. Starting salaries

Step-by-step explanation:

The random variable is the variable that is being descripted by the distribution. In this case, it is the variable "Starting salaries of individuals with an MBA degree".

It can take any values, but its probability is defined by the distribution and its parameter (mean and standard deviation). In theory, it could take negative values, but they would not have any validity in the real world.
