The average human body temperature is 98.6, write 98.6 as a mixed number

Delicious77 [7]

Multiply it by 100 to give you a fraction over 100 then see how many times the numerator (the top number) goes into the denominator (the bottom number) to get a mixed number

<h3>Given:</h3>

Trapezium

Length of BC
Value of "x"

<h3>Solution:</h3>

We can divide the given shape into a triangle and a rectangle.

We'll have to use Pythagoras Theorem.

$\large\boxed{Formula:{a}^{2}={b}^{2}+{c}^{2}}$

In this question we have to find the hypotenuse so we'll have to add.

Let's substitute the values according to the formula.

$BC= {6}^{2}+{7}^{2}$

$BC= 85$

$BC = \sqrt{ 85}$

$\boxed{BC=9.22 \: cm}$

Now, we can find the value of "x"

Adjacent= 7 cm
Opposite= 6 cm
Hypotenuse= 9.22 cm

We can use any one from SOHCAHTOA.

Here I'm using tan.

$\large\boxed{Formula: tan(a)= \frac{opp}{adj}}$

Let's substitute the values according to the formula.

$tan \: x= \frac{6}{7}$

We'll have to use tan inverse.

$x= {tan}^{-1}(\frac{6}{7})$

$\boxed{x=40.6°}$

Classify the equation as a conditional equation, an identity, or a contradiction.

Goryan [66]

Since the equation is a true one, then it is an identity.

<h3>How to illustrate the information?</h3>

It should be noted that the information given is represented as 9(a−4)+3(2a+5)=7(3a−4)−6a+7.

After using the distributive law, the value that will be gotten will be:

15a - 21 = 15a - 21.

Therefore since the equation is a true one, then it is an identity.

Information on a packet of seeds claims that the germination rate is 92%. The packet contains 160 seeds.

xenn [34]

Answer: a. N(0.92, 0.0215)

Step-by-step explanation:

For population proportion (p) and sample size n, the mean and standard deviation is given by :-

The sampling distribution model for p is given by :_

$N(\mu_p,\ \sigma_p)$

, where

$\mu_p=p \\ \sigma_p=\sqrt{\dfrac{p(1-p)}{n}$

We assume that the seeds are randomly selected.

Given : Information on a packet of seeds claims that the germination rate is 92%.

i.e. p= 0.92

The packet contains 160 seeds.

i.e. n= 160

Then , $\mu_p=0.92\\ \sigma_p=\sqrt{\dfrac{0.92(1-0.92)}{160}}\approx0.0215$

Hence, the sampling distribution model for p is:

$N(\mu_p,\sigma_p) = N(0.92, 0.0215)$
