Step-by-step explanation:

3- sin Z = opp/hyp

sin Z = 27/45

Z = sin-¹(27/45)

Z = 37

4- tan C = opp/adjacent

tanC = 24/32

C = tan -¹ ( 24/32)

C = 36.87 ( or 37)

5- cos X = adj/hyp

cos X= 36/45

X = cos-¹ (36/45)

X = 37

6- sin C = opp/hyp

sin C = 14/48

C = sin -¹ (14/48)

C= 17 (or 16.96)

Let’s assume that human body temperatures are normally distributed with a mean of 98.20° F and a standard deviation of 0.62° F.

uysha [10]

Answer: It is such a small percentage of the population that would be considered to have fever at that level.

So, it is not appropriate stringent standard.

Step-by-step explanation:

Since we have given that

Mean = 98.20°F

Standard deviation = 0.62°F

If Bellevue Hospital in New York City uses 100.6°F as the lowest temperature considered to be a fever.

So, $\bar{X}=100.6^\circ F$

So, using the normal distribution, we first find the value of z.

$z=\dfrac{\bar{x}-\mu}{\sigma}\\\\x=\dfrac{100.6-98.2}{0.62}\\\\z=3.87$

Since z = 3.87

So, p = 0.0001 =0.1%

So,It is such a small percentage of the population that would be considered to have fever at that level.

So, it is not appropriate stringent standard.

The sum of two numbers is -9. The difference of the two numbers is -41. What are the two numbers?

Nataly [62]

Answer:

the two numbers are 16 and -25

Step-by-step explanation:

Let the two numbers be x and y

x+y=-9

x-y=-41

By substitution

y=-9-x

x-(-9-x)=-41

x+9+x=-41

2x=-41-9

2x=-50

x=-25

y=-9-(-25)

y=16
