Anna35 [415]

Answer: 0.00102%

Step-by-step explanation:

Given : Human body temperatures are normally distributed with a mean of $\mu=98^{\circ}F$ and a standard deviation of $s=0.61^{\circ}F$

A hospital uses $100.6^{\circ}F$ as the lowest temperature considered to be a fever.

Let x be the random variable that represents the human body temperatures.

$z=\dfrac{x-\mu}{s}$

For x= 100.6, $z=\dfrac{100.6-98}{0.61}=4.26229508197\approx4.26$

Using normal distribution table for z-values for right-tailed area ,

P(x>100.6)= $P(Z>4.26)=0.0000102=0.00102\%$

Hence, the required probability = 0.00102%

Answer:

4) reflexive property of congruence

5) SAS theorem

6) property of Congruent triangles

Step-by-step explanation:

Given:

In ΔXYZ, line YW ⊥ XZ

Also XW≅ZW

Now

4) by reflexive property of congruence that states that any line,object or figure is congruent to itself

hence YW≅YW

5) By SAS theorem that states that if the two corresponding sides and the angle between those sides of two triangles are congruent then the two triangles are said to be congruent.

Hence ΔWXY≅ΔWZY

6) By property of Congruent triangles that states that if two triangles are congruent then their corresponding sides are also congruent.

Hence XY≅ZY !

The scale on a trail map is 0.5 cm : 1 km. The straight distance between 2 huts on the trail is 16.9 cm. What is the actual dist

sesenic [268]

We have been given that the scale on a trail map is 0.5 cm : 1 km. The straight distance between 2 huts on the trail is 16.9 cm. We are asked to find the actual distance between 2 huts.

We will use proportions to solve our given problem.

$\frac{\text{Actual length}}{\text{Scale length}}=\frac{\text{1 km}}{\text{0.5 cm}}$

$\frac{\text{Actual length}}{\text{16.9 cm}}=\frac{\text{1 km}}{\text{0.5 cm}}$

$\frac{\text{Actual length}}{\text{16.9 cm}}\times \text{16.9 cm}=\frac{\text{1 km}}{\text{0.5 cm}}\times \text{16.9 cm}$

$\text{Actual length}=\frac{\text{1 km}}{\text{0.5}}\times \text{16.9}$

$\text{Actual length}=33.8\text{ km}$

Therefore, the actual distance between both huts is 33.8 km.

Someone please help me answer Number 14, PLEASE!

Answer:

b=240

Step-by-step explanation:

We need to find b. In order to this, we must isolate b.

$-17+\frac{b}{8}=13$

Add 17 to both sides

$\frac{b}{8}=30$

Multiply both sides by 8 to remove the fraction

$b=240$
