It is true that in a word problem, instead of calling it the slope, we call it the starting point instead.
Although the two terms are interchangeable, in presenting the mathematical question, we need to use the term starting point so as to refer to the place where the slope starts, and not the whole slope.

SIZIF [17.4K]

Answer:

correct answer = 90%

Step-by-step explanation:

Let x be the percent of the question did she answer correctly.

Given:

An engineering student answered 81 questions correctly on a 90 question test.

Find the percent of the question did she answer correctly.

Solution:

Percentage formula is given below

% answer $=\frac{correct\ answer}{total\ questions}\times 100$

% answer $=\frac{81}{90}\times 100$

% answer $=\frac{81\times 100}{90}$

% answer $=\frac{81\times 10}{9}$

% answer $=9\times 10$

% answer $=90$

correct answer = 90%

Therefore, she answered 90% correctly.

Answer: $H_0:\mu=421$

$H_a : \mu\neq421$

Step-by-step explanation:

A null hypothesis is a type of hypothesis that is used in statistics that assumes there is no difference between particular characteristics of a population wheres the alternative hypothesis shows that there is a difference.

Given: A 37 bag sample had a mean of 421 grams.

Let $\mu$ be the population mean.

Then, the null hypothesis would be:

$H_0:\mu=421$

whereas the alternative hypothesis would be:

$H_a : \mu\neq421$

Answer:

The second bubble

Step-by-step explanation:

In a 30 60 90 triangle as shown here a is always 1/2 the hypotenuse (Which the hypotenuse is 6) and then just add $\sqrt{3}$ to the end of it to get b

<em>So, lets demonstrate</em>

a = 1/2 * 6 = 3

b = a* $\sqrt{3}$ = a $\sqrt{3}$ = 3 $\sqrt{3}$

So,

a = 3

b = 3 $\sqrt{3}$
