Answer:

m<5= 75° Alternate angles are equal

m<6 = 180°-75°= 105 ° Angles on a straight line adds up to 180°

In a rectangle opposite sides are equal so AB= CD

2x+8= 3x+4

3x-2x=8-4 ( combine like terms, the signs will change since they are going over opposite sides)

x= 4

To solve for BC

AD= BC

x+17 ( we know that x=4)

4+17=21

Therefore BC= 21

A highly selective boarding school will only admit students who place at least 2.5 standard deviations above the mean on a stand

VladimirAG [237]

Answer:

The minimum score that an applicant must make on the test to be accepted is 360.

Step-by-step explanation:

Given : A highly selective boarding school will only admit students who place at least 2.5 standard deviations above the mean on a standardized test that has a mean of 300 and a standard deviation of 24.

To find : What is the minimum score that an applicant must make on the test to be accepted?

Solution :

We apply the z formula,

$z=\frac{x-\mu}{\sigma}$

Where, z value= 2.5

$\mu=300$ is the mean of the population

$\sigma=24$ is the standard deviation

x is the sample mean.

Substituting the values in the formula,

$2.5=\frac{x-300}{24}$

$2.5\times24=x-300$

$60=x-300$

$x=60+300$

$x=360$

Therefore, The minimum score that an applicant must make on the test to be accepted is 360.

Using the Law of Sines (sina/A=sinb/B=sincC for any triangle)

sinc/28=sin90/53 (sin90=1) multiply both sides by 28

sinc=28/53 take the inverse of sin (arcsin) of both sides

c=arcsin(28/53)°

c≈31.89° (to nearest hundredth of a degree)

So it is obvious that they rounded to nearest tenth of a degree

c≈31.9°
